Port Cities and Nature: The Experience of Brest Métropole Océane and the Maritime Innovative Territories International Network

Many voices. Greener cities. Better cities.

Just as human activities change the face of our planet, the habits of maritime and port city residents have a disproportionate influence on the fate of coastal and marine biodiversity.

We already know that what happens to life on Earth will depend on how people live in cities, but for ports, two factors further leverage their impact. First, they are the most significant global trade and transportation hubs, meaning they can influence and regulate key processes with huge implications on biodiversity. Second, given ongoing urbanization in coastal regions, their urban areas host an increasing population. Thus, their dense populations and high resource consumption patterns can cause offshore and onshore pollution in sensitive ecosystems, but their sustainable governance offers immense opportunities for reducing footprints and set best practices.

It is also clear that local authorities in port cities, as managers, mediators, regulators and stewards of their natural capital at the closest level to citizens, can make an enormous difference for the sustainable management of biodiversity and ecosystem services. The successful transfer and adaptation of their different experiences through decentralized cooperation is challenging but critical for the conservation and sustainable use of marine and coastal resources. In this context, the urban community of Brest, France, set up an international network of around 20 coastal territories, local authorities and their scientific partners, in North and Latin America, Europe and Asia, called the Maritime Innovative Territories International Network (MITIN), dedicated to promote and develop “blue growth”, the sustainable economic use of coastal and marine resources, through effective collaboration and exchanges.

What can port authorities do?

The mandates and best practices of city governments with regards to biodiversity have been extensively detailed in this blog and in the groundbreaking “Cities and Biodiversity Outlook”, launched at the recent Conference of the Parties of the Convention in Hyderabad, India in October 2012

Decision makers in port city governments, however, can further promote awareness on biodiversity-related issues, and can ensure cost-effective freshwater supply and security through the wise use of wetlands and, increasingly, desalination of sea water (with potential impacts on groundwater salinity and energy consumption). Port city governments can enhance food security by supporting sustainable urban and peri-urban agriculture and aquaculture (which will also reduce coastal and marine pollution), and control urban expansion on sensitive coastal habitats via land-use zoning. They can also protect their cities from the impacts of sea level rise and storm surges by preserving the ecosystems which provide resilience to those coasts (such as estuaries, mangroves and coral reefs), can stimulate development in areas less subjected to these risks, and can participate in early warning systems that minimize actual damage by giving residents and officials time to prepare at critical times.

By applying the right combination of economic incentives and attracting green investments, port cities can ultimately promote the wise use of their natural marine and coastal resources, while also addressing poverty eradication and the economic development of their citizens. Working with retailers and advertisers, as well as with civil society, and implementing sustainable public procurement guidelines, coastal local authorities can promote sustainable consumption. Fish stocks and fisheries are managed and regulated mostly through subnational and local authorities – even when guidelines and quotas are defined by national governments, the enforcement of no-fishing zones and the monitoring of activities and volumes rely heavily of local agencies and authorities.

Port cities also play a crucial role in the prevention, control and eradication of invasive alien species. Shipping can disturb coastal ecosystems by introducing these species through exchange of ballast water and fouling. By establishing treatment protocols for ballast water and ship containers, as well as by introducing biosafety measures, port cities limit the contamination of coastal environment by invasive alien species. Their choices of technologies for urban infrastructure define the ultimate ecological footprint of their cities, their use of regulatory policy tools and voluntary economic incentives can bring greener businesses, and the quality of the urban environment they offer will attract, or not, discriminating citizens to settle, get engaged and pay taxes.

Finally, local authorities in ports will contribute in decisive ways to expand global networks of coastal and marine parks — the 193 Parties to the Convention on Biological Diversity agreed to protect 10 per cent of all coastal and marine areas by 2020 through integrated systems of protected areas and other conservation measures as part of Aichi target 11 — we’re at around 6 per cent now and we’ve barely got another 8 years to reach the deadline!

Brest Métropole Océane and the development of the MITIN network

The urban community of Brest is ranked in the world‘s top-10 for science and maritime techonologies, with more than 1,800 researchers currently developing cutting edge work. As France’s main harbour for the Navy’s fleet maintenance and civilian ship repair, the community owns 5 ports, with different functions (military, scientific research, fishing, trade, leisure), and hosts many centres of excellence in scientific and technological research and education, such as IFREMER and Oceanopolis. As such, the local authority of Brest is involved in different European networks, such as the Conference of Peripheral Port Cities and the Conference of Atlantic Arc Cities, promoting maritime issues including marine and coastal biodiversity.

At the international level, Brest métropole océane supported the creation of a new network, the Maritime Innovative Territories International Network (MITIN). Officially launched on July 13th 2012, MITIN is an initiative of Brest Science Park (Technopôle Brest Iroise), supported by Brest métropole océane and several international partners of the local authority. Today, MITIN gathers 20 maritime territories represented by their technology poles, development and scientific agencies, and local authorities, including the US (San Diego), Mexico (Veracruz), China (Qingdao, Shangaï), Argentina (province du Chubut), Vietnam (Haiphong), Italy (Tarente), UK (Southampton), Portugal (Porto), Spain (Vigo), and Quebec (Rimouski). The network aims at promoting sustainable “blue“ growth and addresses the sustainable use of marine bio-resources, transportation, maritime safety and security, renewable marine sources of energy, marine instrumentation and information technologies.

A web portal has been created to provide virtual spaces for working groups, practical actions and technology transfer. As president of the local authority of Brest, Mayor François Cuillandre also represents port cities in the Sustainable Ocean Initiative, a platform in the Convention dedicated to information sharing on best practices for the achievement of Aichi Targets 6, 10 and 11 related to marine and coastal biodiversity.

What works and what doesn’t

While MITIN is work in progress, we can draw some lessons from its past experience, also to guide future activities. The International Meeting on marine and coastal biodiversity, organised by Brest métropole océane in November 2012, represented an excellent opportunity for Brest partner networks, including MITIN, to reflect on some characteristics of effective decentralized cooperation:

Problems are the same for port cities across the world, but cultural and institutional circumstances are different and the transfer of experiences requires equal efforts from the two sides

The needs of each participating city are different, as are the level of expertise, available materials and suppliers of goods and services. One of the most effective ways to address this is the actual exchange of partners, allowing hosts and suppliers to benefit from a different perspective and further building the capacity of all experts involved, who are then able to work in the context of both cities and institutions. Thus, MITIN identifies priorities, including sustainable uses of marine resources, gathers partners and experts on common issues, offers an information-sharing platform and engages practitioners in the exchange of “know-how”. The network can rely on the Summer University, with training sessions suggested by local scientific stakeholders in Brest and supported by Brest métropole océane.

Proposals need to be systematically action-oriented and relevant to each partner

MITIN focuses its cooperation on the concept of Blue Economy, adjusting its context to the needs of each stakeholder group and economic actor to facilitate engagements and commitments. For instance, the implementation of marine protected areas taking into account local economic activities has proved to be an efficient mean to protect and restore marine stocks and habitats. In this context, Integrated Coastal Zone Management and Marine Spatial Planning are well-tested policy tools for public authorities to manage the growth of maritime activities, taking into account fragile or rich marine ecosystems.

More flexible international or multilateral funding mechanisms need to be put in place to support decentralized cooperation

Very few funding mechanisms exist in this domain, limiting the scope and effect of those productive partnerships to the capacity of participating local authorities. In Europe, the Committee of the Regions promotes the role of local actors to develop regions and all around the world some local initiatives are implemented. The involvement of Brest’s international partners through MITIN reveals the interest and capacity of action of local actors in issues that have been considered mostly from a national point of view for a long time.

But, to be fully efficient, decentralized cooperation would benefit from the development of international or multilateral funding. We therefore plead in favor of the establishment of more mechanisms, either financed by States or international organizations, for instance based on the model of the European Committee of Regions, not only to promote implementation but also to coordinate the funding and technical efforts of various subnational and local authorities.

Scale up lessons learned at a global level

Regarding new partnerships, it is essential to scale up lessons learned at global level, and to keep doors open for the further engagement of different networks and possible partners. In the case of MITIN, further collaboration between Brest métropole océane, its partner networks and ICLEI – Local Governments for Sustainability, an experienced international network gathering local authorities on sustainable development in urban areas issues, is being examined.

Plans and expectations

To expand its objectives, Brest métropole océane has initiated a partnership with the Secretariat of the Convention on Biological Diversity for technical cooperation and dissemination of experiences to CBD Parties and their subnational and local authorities. This partnership implies both the involvement of local stakeholders (main organizations working on biodiversity) and the invitation to its international and European networks to commit.

As such, this initiative is a model for thematic and regional networks of local authorities supported by the Secretariat and ICLEI within the Global Partnership on Subnational and Local Action on Biodiversity, which also includes the Mediterranean network MediverCities supported by Montpellier. Similarly, this partnership will benefit from the technical support of ICLEI and its pioneering Local Action on Biodiversity programme as a global source of expertise in local governance of biodiversity.

Two events, initiated by MITIN members, and supported by Brest métropole océane, will take place this year: a specific workshop organized by the State of Veracruz dedicated to environmental issues in the Gulf of Mexico in September 2013 and, at the end of October, the city of Qingdao (China) will host a Conference on “Blue Economy”, an innovative approach to the management of human production and consumption patterns and the efficient use of natural resources and energy through the use of nature-inspired technologies and solutions that are environmentally beneficial and have wider financial and social benefits. In 2013, Brest métropole océane will also offer to its partners the possibility to attend a summer school university on site.

Finally, Brest and the Secretariat of the Convention on Biological Diversity plan to cooperate on the production of a more detailed study on the role of port cities on marine and coastal biodiversity, building on the recently published Cities and Biodiversity Outlook.

Les Villes Portuaires et la Nature: L’expérience de Brest Métropole Océane et le Réseau International des Territoires Maritimes Innovants

Tout comme les activités humaines modifient le profil de la planète, le comportement des habitants des villes portuaires et côtières a une influence disproportionnée sur le sort de la biodiversité marine et côtière.

Nous savons déjà que ce qui arrive à la vie sur terre dépendra de la manière dont les populations vivent en ville, mais pour les villes portuaires, deux facteurs augmentent leur impact : d’abord, elles sont des plaques tournantes incontournables du transport maritime et du commerce international (ce qui signifie qu’elles peuvent influencer et réguler les principaux processus qui ont d’immenses implications sur la biodiversité) ; ensuite, du fait d’une urbanisation croissante dans les régions côtières, leurs zones urbaines doivent faire face à une population grandissante. Ainsi leurs populations denses et leur modèle de consommation élevée de ressources est une cause de pollution marine et terrestre pour les écosystèmes sensibles des zones littorales, mais leur gestion durable offre d’immenses opportunités pour réduire leur empreinte et mettre en place de bonnes pratiques.

Il est certain que les autorités locales des villes portuaires, en tant que gestionnaires, médiateurs, régulateurs de leur capital naturel, au plus proche des citoyens, peuvent faire une énorme différence pour une gestion durable de la biodiversité et pour les services écosystémiques. La réussite du transfert et de l’adaptation de leurs différentes expériences à travers la coopération décentralisée est un défi ambitieux pour la conservation et l’utilisation durable des ressources marines et côtières. Dans ce contexte, la Communauté Urbaine de Brest, en France, a mis en place un réseau international regroupant une vingtaine de territoires côtiers, d’autorités locales ainsi que leurs partenaires scientifiques, d’Amérique du Nord et du Sud, d’Europe, d’Asie, appelé Réseau International des Territoires Maritime Innovants (RITMI). Ce réseau est dédié à la promotion et au développement de « l’économie bleue », l’utilisation et exploitation durable des ressources marines et côtières, au travers d’une collaboration et d’échanges de bonnes pratiques.

Que peuvent faire des autorites portuarires? 

Les compétences et les bonnes pratiques des autorités locales en ce qui concerne la biodiversité ont été largement détaillées sur ce blog et dans le programme innovant « Les villes et les perspectives de la biodiversité (VPB) », lancé lors de la dernière Conférence des Etats Parties de la Convention qui s’est tenu à Hyderabad, en Inde en octobre 2012.

Cependant, les élus de villes portuaires peuvent promouvoir davantage la sensibilisation sur les enjeux de biodiversité et peuvent assurer l’approvisionnement en eau douce et sa sécurisation via une utilisation raisonnée et rationalisée (coût-efficacité) des zones humides et le recours de plus en plus fréquent au dessalement de l’eau de mer (avec des impacts potentiels sur la salinité des eaux souterraines et la consommation d’énergie). Les villes portuaires peuvent garantir la sécurité alimentaire en soutenant une agriculture et une aquaculture urbaines et périurbaines (ce qui réduira également la pollution marine et côtière) et contrôler l’étalement urbain dans les zones sensibles d’habitats côtiers via des plans d’occupation des sols (Plan Local d’Urbanisme en France). Elles peuvent également protéger leurs territoires des impacts de l’élévation du niveau de la mer et de l’augmentation des tempêtes en préservant les écosystèmes qui apportent la résilience nécessaire à ces côtes (telles que les estuaires, les mangroves et les récifs coralliens). Elles peuvent favoriser le développement de zones moins sensibles à ces risques et peuvent participer à la mise en place de systèmes d’alerte préventifs qui permettent de minimiser les dégâts en donnant aux habitants et aux élus le temps de se préparer.

En développant un bon équilibre entre incitations économiques et en attirant les investissements durables, les villes portuaires peuvent promouvoir l’utilisation raisonnée des ressources marines et côtières, tout en apportant des solutions pour réduire la pauvreté et favoriser le développement économique local. En travaillant avec les commerçants,les publicitaires et la société civile, et en mettant en œuvre des mesures de développement durable dans le cadre des marchés publics, les autorités côtières peuvent promouvoir un mode de consommation durable. Les stocks de poissons sont principalement gérés et régulés par les autorités infranationales et locales – même lorsque les orientations et quotas sont définis par les gouvernements nationaux, l’application plus stricte des zones interdites à la pêche et la gestion des activités et des volumes dépendent fortement des autorités locales.

Les villes portuaires ont également joué un rôle essentiel dans la prévention, le contrôle et l’éradication des espèces invasives. Le transport maritime peut perturber les écosystèmes côtiers en introduisant ces espèces lors du déversement des eaux de ballast et des salissures. En établissant des procédures de traitement des eaux de ballast et des containers des navires, en introduisant également des mesures de sécurité biologique, les villes portuaires limitent la pollution de l’environnement côtier par les espèces invasives. Leurs choix de technologies pour les infrastructures urbaines définissent l’empreinte écologique finale de leur territoire, le recours à des outils d’aide à la décision et des mesures d’incitations économiques, peuvent favoriser des économies plus durables, et la qualité de l’environnement urbain qu’elles offriront sera susceptible d’attirer une partie de la population prête à s’engager et à contribuer à l’effort commun.

Au final, les autorités locales portuaires contribueront de manière décisive à étendre les réseaux internationaux de parcs marins et réserves littorales – les 193 Etats Parties de la Convention sur la Diversité Biologique se sont entendus pour protéger 10 % de l’ensemble des zones côtières et marines d’ici 2020 par l’instauration de zones protégées et autres mesures de protection précisées par l’objectif 11 d’Aïchi – la barre des 6 % est à peine franchie et il ne reste que 8 années pour atteindre cet objectif !

La Communauté urbaine de Brest figure parmi les 10 premières places mondiales en sciences et technologies de la mer, comptant plus de 1 800 chercheurs menant des travaux d’excellence. En tant que principal port français de réparation navale civile et militaire, le territoire est doté de 5 ports aux fonctions différentes (militaires, recherche scientifique, pêche, commerce, plaisance), et héberge de nombreux centres d’excellence dans le domaine de l’éducation et de la recherche scientifique et technologique, tels qu’Océanopolis ou IFREMER. L’autorité locale de Brest est partenaire de différents réseaux Européens, comme la Conférence des Villes Portuaires Périphérique (CVPP), la Conférence des Villes de l’Arc Atlantique (CVAA), pour promouvoir les enjeux maritimes y compris la biodiversité marine et côtière.

Au niveau international, Brest métropole océane a soutenu la création d’un nouveau réseau, le Réseau International des Territoires Maritime Innovants (RITMI). Officiellement lancé le 13 juillet 2012, RITMI est une initiative du Technopôle Brest Iroise, avec l’appui de Brest métropole océane et de plusieurs territoires internationaux partenaires. Aujourd’hui, RITMI rassemble 20 territoires maritimes représentés par leur technopôle, agence de développement, organismes scientifiques et autorités locales. Il comprend : les Etats-Unis (San Diego), le Mexique (Veracruz), la Chine (Qingdao, Shangaï), l‘Argentine (province du Chubut), le Vietnam (Haiphong), l‘Italie (Tarente), la Grande-bretagne (Southampton), le Portugal (Porto), l‘Espagne (Vigo), et le Quebec (Rimouski). Le Réseau a pour objectif de promouvoir une « croissance bleue » durable et aborde l’utilisation raisonnée des bio-ressources marines, du transport maritime, de la sécurité et sûreté maritimes, des énergies marines renouvelables, de l’instrumentation marine et des technologies de l’information.

Un portail Internet a été créé pour mettre à disposition différents espaces virtuels pour les groupes de travail du Réseau, et pour faciliter le développement d‘actions concrètes et le transfert de technologies. En tant que Président de Brest métropole océane, le Maire de Brest François Cuillandre représente également les villes portuaires au sein de l’Initiative pour un Océan Durable, plateforme de la Convention sur la Diversité Biologique dédiée au partage de l’information sur les bonnes pratiques permettant d’atteindre les objectifs d’Aïchi 6, 10 et 11 en lien avec la biodiversité marine et côtière.

Ce qui fonctionne et ce qui ne fonctionne pas

Alors que RITMI vient d’être créé, on peut d’ores-et déjà tirer quelques leçons de son expérience passée, permettant de mieux orienter les activités futures. Les Rencontres Internationales sur la biodiversité marine et côtière, organisées par Brest métropole océane en novembre 2012, a représenté une excellente opportunité pour les réseaux partenaires de Brest, y compris RITMI, présentant les principales caractéristiques d’une coopération décentralisée efficace.

A travers le monde, les villes portuaires doivent faire face à des problématiques similaires, cependant, le contexte culturel et institutionnel varie, c’est pourquoi l’échange d’expérience nécessite une implication égale des deux parties. Les besoins de chaque territoire impliqué sont différents, tout comme le sont le niveau d’expertise, l’équipement disponible et les fournisseurs de biens et services. Une des façons les plus efficaces d’aborder cela est un échange effectif entre les partenaires, permettant aux fournisseurs et aux bénéficiaires de tirer profit d’une perspective nouvelle et d’augmenter ainsi la capacité de tous les experts impliqués, qui sont alors capables de travailler dans le champ des deux villes et institutions. Ainsi, RITMI identifie des priorités, incluant une exploitation durable des ressources marines, rassemble des partenaires et des experts sur des problématiques communes, offre une plateforme d’échange d’information et permet l’engagement des professionnels à échanger les savoir-faire. Le réseau peut s’appuyer sur une Université d’été, avec des sessions de formation suggérées par les acteurs locaux scientifiques de Brest et soutenues par Brest métropole océane.

Des propositions qui doivent systématiquement être orientées vers l’action et doivent être pertinentes pour chaque partenaire. RITMI concentre ses coopérations sur le concept de l’« économie bleue », adaptant son contexte aux besoins de chaque groupe d’acteurs locaux afin de faciliter son engagement. Par exemple, la mise en œuvre de zones marines protégées prenant en compte les activités économiques locales a prouvé son efficacité pour protéger et restaurer les habitats et les réserves marines. Dans ce contexte, la gestion intégrée des zones côtières et l’aménagement de l’espace marin sont des outils testés au service des autorités locales pour gérer le développement des activités maritimes, en prenant en compte les écosystèmes marins riches ou fragiles.

La mise en place de mécanismes de financement international/multilatéral et plus flexible au service de la coopération décentralisée. Très peu de mécanismes de financement existent dans ce domaine, limitant l’étendue et les effets de ces partenariats productifs à la capacité des organisations impliquées. En Europe, le Comité des Régions vise à promouvoir le rôle des acteurs locaux pour développer les régions et des initiatives locales sont mises en œuvre à travers le monde. L’implication des partenaires internationaux de Brest via RITMI révèle l’intérêt et la capacité de l’action des acteurs locaux sur des problématiques qui ont presque uniquement été envisagée d’un point de vue national pendant de nombreuses années. Mais, afin d’être toujours plus efficace, la coopération décentralisée, devrait bénéficier du développement des financements internationaux ou multilatéraux. C’est pourquoi, nous plaidons pour la création de plus de mécanismes, financés soit par les Etats, soit par les organisations internationales, basés, par exemple, sur le modèle du Comité des Régions, non seulement pour promouvoir la mise en œuvre mais également pour coordonner les efforts techniques et financiers d’autorités infranationales et locales.

En ce qui concerne la perspective de nouveaux partenariats, il est essentiel de faire remonter au niveau international les expériences locales et de garder la porte ouverte à l’engagement de différents réseaux et partenaires. En ce qui concerne RITMI, la possibilité d’une plus grande collaboration entre Brest métropole océane, ses réseaux partenaires et ICLEI – Les Gouvernements Locaux pour le Développement Durable, un réseau international expérimenté rassemblant des autorités locales sur la problématique du développement durable des zones urbaines – est actuellement étudiée.

Poursuites et attentes

Afin d’étendre ses objectifs, Brest métropole océane a initié un partenariat avec le Secrétariat de la Convention sur la Diversité Biologique pour une coopération technique et une diffusion des expériences aux Etats Parties de la CDB et de leurs autorités infranationales et locales. Ce partenariat prévoit, à la fois, l’implication des acteurs locaux (principales organisations abordant la biodiversité) et une invitation à ses réseaux européens et internationaux à s’engager.

Ainsi, cette initiative constitue un modèle de réseau thématique et régional d’autorités locales, soutenu par le Secrétariat et ICLEI, dans le cadre du Partenariat mondial sur l’action infranationale et locale sur la biodiversité, qui inclut également le réseau méditerranéen MediverCities, soutenu par Montpellier. De même, ce partenariat bénéficiera du soutien technique d’ICLEI – Les Gouvernements Locaux pour le Développement Durable  et de son programme innovant « Action Locale pour la Biodiversité », comme source mondiale d’expertise dans la gestion locale de la biodiversité.

Deux événements, initiés par les membres de RITMI, et soutenus par Brest métropole océane, se dérouleront cette année : un atelier organisé par l’Etat de Veracruz et portant sur les problématiques environnementales du Golfe du Mexique en septembre 2013 et, à la fin du mois d’octobre, la ville de Qingdao (Chine) accueillera une conférence sur « l’économie bleue », une approche innovante pour la gestion de la production humaine,des habitudes de consommation, une utilisation efficace des ressources naturelles et de l’énergie par le développement de technologies inspirées de la nature et des solutions aux nombreux bénéfices sur le plan environnemental, économique et social. En 2013, Brest métropole océane offrira également à ses partenaires la possibilité de participer à une université d’été.

Enfin, Brest et le Secrétariat de la Convention sur la Diversité Biologique projettent de coopérer pour produire une étude détaillée sur le rôle des villes portuaires sur la biodiversité marine et côtière, basée sur la récente publication « Les villes et les perspectives de la biodiversité».

Positive Visions for Sustainable, Resilient, and Equitable Cities

Many voices. Greener cities. Better cities.

Societies need spaces for radical thinking to confront not only the climate-change challenges of the future, but also the present-day conditions that create, reinforce, and reproduce vulnerability.

It is beginning to feel like the anticipated future under climate change is even closer than we once thought. After a particularly harsh hurricane season in North America and following another year of record high global temperatures in 2017, many people recognize that we are entering a new climate reality. Current and projected trends in extreme weather events highlight the need for fundamental and transformative change, to improve living conditions for urban residents.

It seems increasingly clear that urbanization pressures and climate change are on a collision course in cities all over the world. Cities are influenced directly by climate change as they deal with increased extreme weather events such as tropical storms, hurricanes, flooding, heat waves, and prolonged droughts. Therefore, the need for adaptation takes on a particular urgency when it comes to municipal policy. Indeed, municipal governments might be best placed to mobilize resources in the face of sluggish international government agreements and the inaction of their federal counterparts. From coast to coast, municipalities big and small are developing ambitious climate action plans. For example, New York City famously vowed to divest billions of dollars for their pension funds from companies in the fossil fuel industry; San Diego is planning to be 100 percent renewable by 2035; San Francisco announced its plan to honor the Paris Agreement through a combination of strategies to reduce waste, increase sustainable transportation, switch to renewable energy, and improve urban tree canopy; meanwhile, Miami is elevating roads, upgrading stormwater infrastructure, and building sea walls in exposed areas.

Out of this need emerged the Urban Resilience to Extreme Events Sustainability Research Network (UREx SRN), formed in 2015 with funding from the US National Science Foundation. Bringing together over 100 researchers and practitioners in ten Latin American and North American cities, the UREx SRN’s mission is to build sustainable, resilient, and equitable futures. Working with communities and residents to develop positive visions of the future is a critical component of resilience and sustainability planning, providing an opportunity to step outside the dominant dystopian narratives of our futures and to develop pathways from the present to a good Anthropocene. A keystone of the UREx SRN approach is a series of workshops in each of the network cities, in which scenarios are co-developed. The “movers and shakers” of municipal decision-making are invited, thus bringing together municipal officials, a broad spectrum of civil society groups, community leaders, and sometimes residents. Developing the workshops in partnership with municipal actors who have a pulse on the city allows us to ensure that the scenarios support ongoing processes and future planning. For instance, if a city is extending a light-rail line, we may choose to create a scenario dealing with transit and connectivity to explore the impact of alternative policies. Workshops yield rich data in a variety of formats —maps, timelines, transcripts, narratives, vignettes—from which representations of the future emerge.

We have already completed scenario workshops in San Juan (Puerto Rico), Valdivia (Chile), Harlem (New York), and Hermosillo (Mexico), where a wide variety of positive visions emerged. For example, in San Juan participants envisioned a future of food and energy self-sufficiency for the island; in Harlem residents thought of a future in which their community was resilient to increasingly severe heat waves; in Valdivia participants imagined a new paradigm of “living with water” where people embraced their wetland ecosystems. In the next two years, we will conduct additional workshops with the cities of Phoenix (Arizona), Baltimore (Maryland), Syracuse (New York), Portland (Oregon), and Miami (Florida). Being at the halfway point, it seems fitting to offer some reflection on what we have experienced and learned thus far.

Figure 2: Participants in San Juan (Puerto Rico) working through different activities during a scenario workshop in 2016. Photo: Authors.

We have learned a lot about workshop design. By now, we have formalized our workflow even though we constantly adjust our activities based on feedback from facilitators. Our day starts with an exploration of historical trends and vulnerability from social, ecological, and technological perspectives. For instance, in our workshop in Hermosillo, we mapped together indicators of social vulnerability, alongside topographical analyses to identify low-lying areas, and information about the size and age of the water pipe infrastructure to show the parts of Hermosillo most vulnerable to urban flooding. Participants are assigned to tables that represent specific city imaginaries that we modify with our local team of city practitioners to make them relevant to their context. For example, the ever-popular green city imaginary might turn into the golden city imaginary for South Phoenix to reflect its desert environment and culture. The day is structured to go from formulating broad aspirations to identifying concrete strategies to developing rich narratives. Activities alternate between formal analytical and informal creative approaches to elicit different kinds of knowledge and information. Our outputs are multidimensional and complex. Building upon the participants’ stated goals and aspirations for their vision, during the workshop participants identify specific strategies to fulfill those goals, they construct timelines to determine when and how strategies will be deployed, draw maps of where they would implement strategies, outline governance actors who will be responsible or affected by the strategies, and finish up the day by creating a narrative about the future of that vision. Following the workshop, dynamic models capture the biophysical dimensions of the changes that stakeholders wish to see in their city. However, models are just one output, other products such as design renderings, vignettes, and qualitative analyses are used to explore the alternative scenario visions.

Our workshops are participatory and, by design, we invite a diverse group of municipal stakeholders to the table. This is our strength and our challenge. It is our strength in that we get a picture of the future that reflects truly interdisciplinary, rich, and nuanced points of view. However, it also presents a challenge. It is our challenge because participants do not have equal footing in the political landscape of their cities and these dynamics carry into our workshops, even when efforts are made to amplify marginalized voices. Furthermore, we recognize our privilege as researchers. Our positionality with respect to these stakeholder groups is sometimes uncomfortable as we find ourselves both confronting and participating in reproducing historical patterns of inequality. Even the very act of thinking about the long-term future can be seen as a privilege of those who have their immediate needs covered. We are also cognizant that the benefits of the workshop and the visioning exercise are likely to be unequally distributed among stakeholders in the room.

Thinking about transformational change is challenging. In our workshops, we have scenarios that are meant to address immediate challenges that cities face—e.g., flooding—and some scenarios that are intended to explore more utopian futures—e.g., a socially just city. We refer to the former as “adaptive scenarios” and the latter as “transformative scenarios”. However, even among the transformative visions, we encounter a lot of shorter-term thinking that fails to challenge the status quo. Myriad factors might explain the lack of more innovative ideas. For example, to push thinking outside of the box, people have to dare to suggest unusual things. It is indeed daring to say unusual things in front of a very diverse group of actors who may or may not know or trust one another. Having more homogenous groups can help participants feel more at ease and reduce fears of ridicule. Yet, the second ingredient of innovation has to do with the idea of “bricolage”, that is, the combining in creative ways things (methods, perspectives, problems, and interventions) that do not often go together. Finding the right mix is very much a work in progress.

So, why do we create these positive visions of the future? Fernando Birri’s[1] words on the need for utopia resonate with our purpose:

“Utopia is something that sits on the horizon. Every time you get ten steps closer, utopia seems to move ten steps further. No matter how much you walk, utopia will always be out of reach. So what’s the point of chasing utopias? Precisely that, it keeps you walking.”

We believe that societies need spaces for radical thinking to confront not only the climate-change challenges of the future but also the present-day conditions that create, reinforce, and reproduce vulnerability. While we feel that our scenario workshops can and should push the boundaries further, they nevertheless serve as spaces to produce complex, richly-described, world-building visions of a future that are full of nuance and tradeoffs. That is, we offer a model to open up the physical and mental spaces to imagine alternatives and to create a solution space where we can question critically the path that we are on. Visualizing positive futures is meant to inspire—but more importantly, it is meant to guide action and forge the necessary alliances to push for change.

Positive Youth Development in Urban Environmental Education

Many voices. Greener cities. Better cities.

Environmental education is often associated with environmental learning and pro-environmental behaviors. Some approaches to environmental education, however, also enable young people’s personal growth through the development of confidence, self-efficacy, and other assets that support an individual’s well-being. This chapter explores the intersection of urban environmental education and positive youth development. It can inform teachers, environmental educators, science educators, youth workers, and others who want to advance environmental learning and a positive developmental trajectory for young people in varied educational settings, such as school classrooms, after-school programs, community organizations, youth development organizations, churches, camps, nature centers, science centers, museums, and gardens.

Positive youth development is an assets-based approach for cultivating competencies essential to personal well-being.

We begin by defining positive youth development and applying it to environmental education. We then describe three programs from the U.S. and Australia to illustrate different pedagogies for integrating positive youth development in environmental education aimed at urban sustainability. By “youth,” we refer to the transitional period between childhood and adulthood, which varies across cultures. The United Nations defines youth as individuals age 15-24; however, others include children younger than 15 or young adults older than 24 in their definitions. The programs we describe also included some children younger than 15.

A paradigm shift in the youth development field has occurred from a focus on reducing specific problems like unintended pregnancy or drug use to “positive youth development,” which builds upon young people’s strengths to develop competencies essential to well-being. Among multiple frameworks describing positive youth development, one of the most comprehensive describes four categories personal assets promoting well-being: physical (e.g., good health habits); intellectual (e.g., critical thinking, good decision-making); psychological (e.g., positive self-regard, emotional self-regulation); and social (e.g., connectedness, commitment to civic engagement) (Eccles and Gootman, 2002). In addition to its emphasis on strengthening assets, positive youth development acknowledges that developmental experiences do not occur as isolated events, but throughout young people’s daily lives as they interact with peers, family, and non-familial adults in schools, after-school programs, and their broader communities.

Settings that promote positive youth development in the U.S. have been found to share similar characteristics (Eccles and Gootman, 2002):

  • Physical and psychological safety (e.g., safe facilities, safe peer interactions);
  • Appropriate structure (e.g., clear and consistent expectations);
  • Supportive relationships (e.g., good communication);
  • Opportunities to belong (e.g., meaningful inclusion);
  • Positive social norms (e.g., rules of behavior, values and morals);
  • Support for efficacy and mattering (e.g., responsibility granting, meaningful challenge);
  • Opportunities for skill building; and
  • Integration of family, school, and community efforts.

The more of these features within an urban environmental education program, the more likely that positive youth development outcomes will result. However, all features need not be present and some might require adaptation to be culturally relevant in other countries.

Youths’ physical and psychosocial development is also influenced by the quality of the urban environment, such as environmental toxins, noise, indoor air quality, and access to green space (Evans, 2006). Urban environmental education can enable young people to play a role in ameliorating environmental conditions that negatively impact well-being. Around the globe, youth have demonstrated their capacity to assess and act to improve environmental conditions in cities (Hart, 1997, Chawla, 2002). When youth have genuine opportunity to address environmental concerns, they can develop valuable personal assets and also increase their own and others’ well-being by enhancing urban environments (Figure 1). In short, urban environmental education can promote positive youth development and youth, in turn, can positively contribute to urban sustainability and resilience.

Figure 1. Urban environmental education that encompasses young people’s participation in improving urban environments can also build assets promoting their well-being, while also changing environmental conditions that impact youth development.

Studies suggest that when youth participate in programs where they act positively for the environment, they themselves grow positively in various ways (Schusler and Krasny, 2010). For example, Hawaiian students working together to select, investigate, and act on a local environmental issue improved their critical thinking; reading, writing, and oral communication skills; familiarity with technology; self-confidence; and citizenship competence (Volk and Cheak, 2003). A food justice education program in New York City proved a valuable developmental experience for youth because it offered somewhere to belong, be pushed toward developing one’s potential, grapple with complexity, practice leadership, and become oneself (Delia, 2014). The evaluators of two environmental service-learning programs in East Africa, Roots & Shoots and Wildlife Clubs of Uganda, found that youth in both programs most valued forming relationships with club members, leaders, and community members as an outcome of environmental education (Johnson-Pynn and Johnson, 2010).

While more research is needed into the opportunities and barriers of integrating positive youth development with urban environmental education, the two can be synergistic when programs are intentionally designed with both in mind. To illustrate the synergy that arises between urban environmental education and positive youth development when youth are offered genuine opportunity to effect environmental change, we describe three programs below. The first involves young people in participatory action research through a child-framed approach. The second develops young people’s leadership capacities as peer educators. And the third facilitates youth civic engagement through local environmental action. In each urban environmental education example, young people were given the opportunity to understand and effect change in urban environments and, as a result, also developed assets promoting their own well-being (Figure 1).

Youth as co-researchers

Children and young people are experts on their own lives, yet research involving children is often conceived of and led by adults. Barratt Hacking, Cutter-Mackenzie and Barratt (2013) call for including children as researchers rather than objects of investigation. To that end, the project “Is ‘Nature’ Diminishing in Childhood? Implications for Children’s Lives” engaged young people in Australia in research about childhood and nature from their own perspectives. The project used a child-framed methodology incorporating qualitative and quantitative research in five distinct stages. It involved 10 children ages 9-14 as co-researchers in each of two sites, one urban and the other an urban fringe suburb.

When environmental education enables children and youth to contribute to improving urban environments, it can not only increase cities’ sustainability and resilience but also foster young people’s personal growth.

Stage 1 involved training sessions where the children and youth learned about qualitative research, specifically ethnography (participant observation, semi-structured interviews) and arts-based methods (photography, video, mapping), which enabled the children to study themselves and local culture (Cutter-Mackenzie, Edwards and Widdop Quinton, 2015). One child’s description of this experience was typical: “I am excited about being able to voice my opinion…There are lots of young people who are passionate to be heard, but this is the only project I have heard of or taken part in that allows them to do so.” Such opportunity to be heard may contribute to positive developmental assets, such as self-efficacy and a sense of social integration.

In Stage 2, children and youth conducted research over two months examining nature-deficit disorder within their own cultural settings. The children received a device with Wi-Fi and GPS for mapping everyday experiences, appropriate research protocols, and a secure dropbox for uploading data. The latter encouraged children and youth not only to take responsibility for their data but also begin preliminary analysis (Barratt Hacking et al., 2013). Stage 3 involved children analyzing their data during research think tanks completed over one intensive session. Participants presented, discussed, mapped, and analyzed their findings. Focus group interviews with the children co-researchers and their parents or guardians also served to triangulate the research findings.

Stage 4 incorporated an online survey that the children co-researchers co-developed with researcher Cutter-Mackenzie. Finally, Stage 5 centered on disseminating the young people’s research to academics, practitioners, and other children. The young people prepared ways to communicate their findings including a documentary and photomontage (Figure 2).

Together the stages of this child-framed methodology highlight how youth can genuinely engage as research collaborators. Through such experiences, children may develop positive developmental assets, such as self-efficacy, connectedness, and research, critical thinking, and communication skills. The results of children’s research also may enhance understanding of children’s experiences of nature in ways that can inform design and management of urban environments (Figure 1).

Youth as peer leaders

Peer education involves people with similar characteristics or experiences learning from each other. Used successfully in the health field, it also can be effective in other arenas, including environmental issues (de Vreede, Warner and Pitter, 2014). Evidence suggests that educating teens to facilitate learning experiences for younger youth can have positive developmental impacts for both younger program recipients and “teens as teachers” (Lee and Murdock, 2001). This strategy provides teens with ownership over the direction of program activities, leading to investment in the outcome of their work (Larson, Walker and Pearce, 2005).

A peer education or “teens as teachers” strategy was piloted in a 4-H environmental education initiative in New York City during the summer of 2015. 4-H is the youth development component of the Cooperative Extension System at many US public universities. Twenty New York City 4-H teens attended the 4-H Career Exploration Conference at Cornell University, where they participated in science and leadership mini-courses led by faculty and staff. During the closing assembly, New York City 4-Hers engaged over 400 peers and adult volunteers in creating “Pollinator Seed Bombs” as part of the National Pollinator Initiative, a US presidential directive to conserve pollinators and thus protect the nation’s food supply. Seed bombs are compressed bundles of clay, compost, and/or soil containing seeds that can be tossed into a bare patch of land to grow new plant life (kidsgardening.org). The 4-H teens and adult volunteers pledged to share their new knowledge and seed bombs with friends and 4-H clubs in their respective communities. One New York City 4-H Peer Educator reflected, “I could see action being taken to improve the world and I was proud to have been a part of it!” This illustrates how participating as an environmental peer educator contributed to this teen leader’s self-efficacy and feelings of mattering, which are positive developmental assets.

When they returned home, the New York City 4-H teens also served as “teen teachers” for the 4-H Exploring Your Urban Environment summer day camp program (Figure 3). The teens were trained to implement a 5-week program with younger youth in eight community agencies in New York City. The teen leaders connected 392 youth to their communities through service-learning opportunities that promoted environmental stewardship and community beautification. In a survey assessing program impacts, all 35 teen teachers agreed or strongly agreed with the statement: “I can make a difference in my community through community service;” commitment to community service is a social asset for positive youth development. Teens’ psychological assets were also enhanced as reflected by their agreement or strong agreement with the statement, “I am more confident in helping others.” These results align with our conceptual framework (Figure 1), highlighting the positive impact that connecting youth to their environment in meaningful ways can have for the youth as well as their environment and communities.

Youth as civic actors

Youth civic engagement refers to young people developing their civic capacities by actively collaborating with others to shape society. One form of youth civic engagement is environmental action, whereby learners collectively analyze a problem and act to solve it. Environmental action can involve directly improving the environment, such as planting native vegetation to restore habitat in a city park, or can indirectly influence others to act through education or policy advocacy. Critical to environmental action is shared decision-making; participants collaborate in defining a problem and then envision and enact solutions (Jensen and Schnack, 1997; Hart, 1997). Adults can experience tensions in sharing decision-making power; navigating these tensions is essential to ensuring genuine opportunity for youths’ participation and positive development (Schusler, Krasny and Decker, 2016).

A youth development specialist and an environmental educator collaborated in an after-school program to facilitate a project in which seven middle school students produced a documentary about “Green Homes” in the City of Ithaca and surrounding towns in upstate New York. The adult leaders chose the project focus, i.e., producing a video about green building, and invited youth to participate. Youth then made decisions with educators’ guidance throughout all facets of video production over seven months, from planning to filming, editing, and debuting to area residents their 18-minute documentary. The role of the adult leader and youth participants in decision-making in this project reflects results of a study on youth environmental action programs, in which educators spoke about striking a balance between providing needed guidance as well as opportunities for youth to assume decision-making and leadership (Schusler et al., 2016).

The students’ video featured three local homes demonstrating building with natural materials, recycled materials, and renewable energy. It also included a “green home” for dogs and cats at the Tompkins County Society for the Prevention of Cruelty to Animals. The “pet home” highlighted the use of recycled materials, natural lighting, a geo-exchange heating and cooling system, and native landscaping.

Participatory action research, peer education, and youth civic engagement can lead to positive change for both urban environments and youth living within them.

Youth reported gaining knowledge about green building and being motivated to do more. As one youth said, “it’s really inspired me to look more at our environment and what I can do to help.” They also spoke of developing skills in video production, problem-solving, communication, teamwork, interacting with adults, persisting to complete a long-term project, and being patient. They valued the opportunity to contribute to their community. As one reflected, “This is going to have an impact on how people build their homes. People that see [the video], at least they’re going to do some of the minor things talked about. And maybe when they see that kids have done something like this, people will give the kids much more respect in the community.” This form of indirect environmental action—youth acted to try to influence residents to make environmentally friendly choices—demonstrates one way that young people develop assets while educating others towards increased urban sustainability (Figure 1).

Conclusion

Participatory action research, peer education, and youth civic engagement are three approaches that have been used in urban environmental education to advance sustainability and foster positive youth development. These three approaches are not mutually exclusive; for example, youth environmental action often involves young people as researchers to understand a situation before proceeding in collective action to change it for the better, and thus integrates participatory action research and civic engagement. All three approaches value young people’s capabilities, build upon their strengths, and offer opportunity for genuine, meaningful participation with the potential for impact on the environment and their communities. They also require adult leaders who provide a caring environment, as well as appropriate levels of guidance, expectations, and freedom for youth to take on leadership and other responsibilities. Through such experiences, young people can contribute to creating more sustainable and resilient cities while developing valuable physical, intellectual, psychological, and social assets that enhance personal well-being.

Practical Advice for the Design of Greenways

Many voices. Greener cities. Better cities.

A review of Designing Greenways: Sustainable Landscapes for Nature and People (Second Edition), edited by Paul Cawood Hellmund and Daniel Somers Smith. 2006. ISBN 1-55963-325-5. Island Press, Washington. 270 pages. 

Greenways (GW)—from  wide wild areas to narrow urban trails—are linear bands of land and water designed and managed for multiple purposes such as nature conservation, flood water management, water quality protection, recreation and many other social functions. Revalued since the middle of last century, when ecology became prominent in planning and design, and strengthened by a solid theoretical framework (island biogeography and landscape ecology) and by analysis tools such as GIS and remote sensing, GW have a  renewed popularity through their significant social and ecological functions, performing many services at the same time.

DesigningGreenwaysCoverIn this collaborative manual editors Paul Cawood Hellmund and Daniel Somers Smith explain the biophysical natural and social ecological functions of GW, and how they can help to solve fragmentation, conservation and functional problems of the landscape in a changing world adding value to ecosystems and people alike.

Paul C. Hellmund is an educator, landscape planner + designer, director of the Conway School of Landscape Design in western Massachusetts, North America. His co-author, Daniel Somers Smith has a background in forest science and is an educator in environmental studies. Other chapters that complete the work are due to R.F. Noss, M.W Binford, R. J. Karty and L. Fisman. In their contributions all authors emphasize the imperative to find a balance between nature and people being creative and critical as a key factor in building sustainable landscapes through collaborative and adaptive design.

WP_20141226_001Designing Greenways belongs to a series books with mentors such as Design with Nature (McHarg 1969), The Granite Garden: Urban Nature And Human Design, (A. W. Spirn 1985), and more recent books such as Green Infrastructure: Linking Landscapes and Communities (M.A. Benedict and E.T. McMahon, 2006), Sustainable Infrastructure: The Guide to Green Engineering and Design (S. Bry Sarte 2010), Green Infrastructure: A Landscape Approach (D.C. Rouse and I. F. Bunster-Ossa 2013), just to mention a few. All these works have a common theme: the aim to broadcast the benefits of green infrastructure taking advantage of the natural landscape as mitigation efforts in a world of social and ecological fragmentation.

The six chapters Designing Greenways, including a special chapter on riparian GW (Chapter 4) present definitions, conceptual theoretical and practical frameworks, scientific knowledge based on an abundant bibliography and case studies, describing the multidimensional GW functions and various human activities that impact corridors. Chapter 5 gives a framework to understand the connections and relationships between Society and Nature.

The key chapter in this book (chapter 6) provides a useful method in five stages to guide the conceptualization and planning of GW projects. This tool, of great use for applications in design, integrates concepts and technical outfits from previous chapters.

Although the book seems to be directed at the American readers—most of the examples noted are U.S. based—the content has a global scope, giving readers most of what they need to know about these issues. To me, here is the only weakness shown in this book.  In a global world there are many enriching GW examples in other parts of the world. These would have been interesting to mention.

Authors describe the evolution of GW in the USA from parkways in the 1860s, when mentor Olmsted recognised the great potential of linear greenspace to connect neighbourhoods providing access to city parks. No reference is given to influences of Olmsted’s travels in China and Europe, which were definitely inspirational sources linking also to a predilection for the pastoral picturesque architecture of the English countryside, a model that has lasted until the present day. Early English influences can be also found in the green belt policy, a restriction of building around cities that can be traced back to the ancient times. Leaving aside this, Designing Greenways can be considered a masterpiece, being comprehensive from different theoretical perspectives and practices of the multiple disciplines involved in a GW design and implementation.

The book succeeds posing the significance to work in achieving landscape integrity without forgetting that GW are not a conservation panacea. The features that strengthen the corridors—such as linearity, connectivity, accessibility, multitasking—represent at the same time many weaknesses. For example, the high ratio of edge to interior make the ecology of GW very vulnerable to human pressure, predation and biological invasions.

GW projects are nowadays popular because of their multiple benefits. A disadvantage of this popularity is that they are associated with the wrong assumption that they are relatively easy to implement. They are not, and along the pages the authors confront us with the reality of the real world. They warn readers not to be dazzled by the many attractive benefits, calling us to reflect that designed GW projects, in order to succeed, should be integrated in the landscape. They recommend that designers must firstly understand the structures and functions of the system they want to restore. Secondly, they should move to the project stages by answering a series of strategic questions through spatial (local to global) and temporal scales, being aware of possible risks and failures that can result from oversimplification or wrong assumptions.

This book presents scientific information in a way that may be accessible to non-specialists integrating scientific principles into a comprehensive design method. Easy to read from start to finish, it can be used in several ways: as a unit, with a focus on some chapters following personal interests, or as a guide.

Although eight years have passed since its publication Designing Greenways remains valid as a great contribution and provides a practical guide for planners, landscape architects, educators, students, citizen groups and conservationists to move from theory to action.

I strongly recommend this book.

Practicing Community Environmental Education in Urban Settings

Many voices. Greener cities. Better cities.

Community environmental education prioritizes community wellness, and uses learning in and about the environment as a means towards community wellness and healing. It draws from place-based, youth and community development, participatory, and resilience approaches in environmental education. Recognizing that community environmental education is an emerging field lacking a clear definition (Aguilar, in revision, Aguilar, Price and Krasny, 2015), here we use a definition developed in the U.S. urban context (Price, Simmons and Krasny, 2014): “Community environmental education aims to enhance a community’s wellness through thoughtful environmental action. It fosters collaborative learning and action, taking into account the social, cultural, economic, and environmental conditions of a community.”

Community environmental education uses environmental learning and action to foster community wellness in cities and other settings.

The term community also has multiple definitions, including those built around a common location, social connections or belonging, cultural identity, and interests (Delanty, 2003). Our use of the term integrates local (e.g., a neighborhood), common interests (e.g., youth development, organic food production), and relational or belonging aspects of community, which is consistent with our focus on community wellness. We define community wellness as social, environmental, and economic conditions that support health and quality of life, including the presence of healthy green spaces, food, and water, and opportunities to engage in healthy activities with others. Although environmental education focusing on community wellness can occur anywhere, much of our understanding of community environmental education comes from work in cities.

Because building connections among people is important to achieving community wellness, a learning theory that emphasizes how learning occurs through interaction with others is useful in elucidating the learning process and outcomes of community environmental education. Social learning encompasses a group of theories that have in common a focus on learning through interactions with others and with the environment (Wals, 2007).

Two social learning theories used in understanding environmental education include communities of practice and cultural historical activity theory. For example, Aguilar and Krasny (2011) applied communities of practice theory to understanding how learning occurs in environmental after-school programs in small cities in Texas, and Krasny and Roth (2010) applied cultural historical activity theory to watershed programs occurring near Victoria, British Columbia. Importantly, these two theories privilege not just the knowledge and perspectives of professionals, but also of community members and of youth participants in environmental education programs. For the urban environmental educator, these theories enable understanding of how learning occurs in programs designed to foster individual and organizational transformations leading to community wellness.

Communities of practice

Originally developed to understand how people learn a craft or skill through interactions with more skilled craftsmen, communities of practice theory examines individual and group identity formation and transformation as a learning process. According to Wenger (1998), a community of practice is a place where people with a common interest or concern engage and become members, agree on and pursue a particular enterprise (e.g., community wellness), and cultivate a common repertoire (e.g., cultural values). The framework considers learning as a social process that occurs as individuals participate in groups associated with a specific physical, historical, and cultural context, often in an apprenticeship manner around a common interest or concern (Lave and Wenger, 1991). Researchers have used this framework to identify apprenticeship-like approaches to learning, while others have examined individual identity and power differentials as a result of participation in communities of practice.

Water Watchers: an environmental education community of practice in Austin, Texas

Water Watchers (organization name has been changed to protect participants’ privacy) is an environmental education program that engages low-income youth in Austin, Texas, whose mission is to: “advance personal and academic achievement through environmental monitoring, education, and adventure.” It provides an example of how program staff’s attention to multiple elements of a community of practice fosters youth engagement. During the academic year after the school-day ends, program staff transport students to test water quality at various sites, and then to program headquarters where students socialize, share food, and do homework with peers who tested a different site. During the summer, staff transport students to their water monitoring sites, after which they go swimming or on a field trip. Through this process, Water Watchers has developed a community of practice, including membership, common enterprise, and shared culture (Aguilar, in press).

A community of practice relies on consistent membership with multiple entry points for joining. Water Watchers offers meetings through the year, provides transportation and a stipend (thus encouraging attendance), offers multiple activities and volunteer opportunities, and brings in speakers and community members. This allows students to participate for different reasons: they like science, they want to be with friends, their teacher recommended them, or they simply want something to do after school.

The program common enterprise revolves around youth development—including academic achievement, social support, agency and empowerment—and around environmental stewardship, both of which foster community wellness. While students often identify the program enterprise as one of water-quality monitoring and socializing, they also acknowledge the program has given them a voice and feelings of respect and acceptance. The program leaders feel students should leave the program “prepared to create a life for themselves that will be better,” and thus ask students to develop goals not only for program participation, but also for their school and family lives. Students work as mentees until they pass a test to become mentors. Mentors in turn develop confidence in their skills as they help newcomers with water testing procedures. Students also apply their water quality knowledge in new arenas, like canoeing and service-learning. Finally, the community of practice includes trajectories that enable members to expand their academic and social skills and bridge with other communities of practice.

Water Watchers also projects a shared culture of respect for each participant and of helping each other. This culture is reinforced when students depend on one another for a successful water test, and through overnight camping and trips to learn about colleges. For example, an African American male who had recently opened up about his homosexuality on an all-boys overnight trip found acceptance rather than ridicule in the Water Watchers community. Another student admitted that high school was a difficult place to feel accepted, but Water Watchers made it easier for her to find a sense of belonging.

Social learning encompasses a diversity of learning theories, all of which focus on learning through interaction with others.

In addition to consistent membership, common enterprise, and shared culture, Water Watchers provides for needs like food, financial assistance in the form of a stipend, and a base for homework and recreation. These services result in a “safe space” and enable a “sense of belonging” for students, many of whom come from unstable homes. In short, Water Watchers empowers participants by improving their social and educational skills, and fosters community wellness through these youth development outcomes and monitoring water quality.

Cultural historical activity theory

Cultural historical activity theory is based on the idea that humans change or learn when they engage in productive activity within a particular cultural and historical context and environment, and in doing so, they change that environment. Productive activity occurs within an activity system, which is comprised of a goal or outcome for the activity, tools, rules, object, subjects, community, and division of labor, as well as the interaction of these elements (Engeström, 1987). Learning occurs through interaction of the learner with other components of this system.

Learning also occurs when contradictions between different elements of the activity system generate conflicts; for example, when rules specifying how to conduct an activity are not consistent with project goals. This can lead to transformations or expanding the activity to include new rules, tools, or goals. Further, one activity system may produce outcomes that are used by another activity system, such as when knowledge produced through a water monitoring activity system is used by policy makers in a legislative activity system. In short, a learning activity system is dynamic and has multiple interactions among its elements and with other activity systems, which can lead to transformation of the activity system and related learning.

By applying cultural historical activity theory to two cases in South Africa—one involving organic agriculture, and the other medical wastes—we expand North American notions of community and urban environmental education that have focused largely on youth audiences. The lessons drawn from the two cases about identifying and resolving contradictions through interactions among academic, professional, and practical knowledge holders, leading to transformations and outcomes consistent with community wellness, are relevant to community environmental education more broadly.

In 2008, Rhodes University, which has cultural knowledge that functions as activity system “tools,” and the South African Qualifications Authority, which makes educational policies and standards and thus provides “rules,” began implementing the Researching Work and Learning program in environmental education. The Isidore Organic Network and its marketing arm Earth Mother Organic, constituted one research site (Mukute, 2010). In trying to address growing demand for organic produce in Durban, these organizations faced challenges meeting organic standards, getting certified as organic producers, and becoming profitable. Cultural historical activity theory, in particular its focus on collaborative learning, transformations of current practice, and contradictions, is useful in understanding how the organic farmer group and its stakeholders sought to overcome obstacles.

Through collaboration with Rhodes University researchers, members of the organic agriculture organizations used a series of steps to contribute to expansive social learning at the local level, and potentially to education nationally. They analyzed Isidore and Earth Mother Organic agriculture and agribusiness practices, which surfaced key challenges and their underlying causes (contradictions). Then they collectively developed and implemented a solution to address the contradictions.

Over 20 organic farmers, trainers, and marketers jointly defined key challenges, surfaced their causes, and developed solutions in an expansive learning process. They identified the goal of their collaborative learning as human health, wealth, and environmental sustainability—which could only be enabled by a qualitatively new practice. The research participants decided to work on the contradiction between organic regulations (rules) and local social-ecological conditions (community). They concluded that this contradiction was caused by lack of collaborative linkages in the organic sector, which in turn was explained by: difficulties in making a profit, part of which would be used for collective learning and innovation; historically constructed cultural barriers among organic value chain actors and associated low levels of trust; strong culture of individualism fostered by past failures of cooperatives; and inadequate infrastructure to support the organic farming movement, including collection centers, training, inspection, and certification.

Responding to this contradiction, the project conducted a workshop which led to formation of a Green Growers Association consisting of organic farmers, trainers, marketers, certifiers, and the municipality, with the goal of linking and coordinating learning and actions of the Durban area organic farming community. The project also identified 11 stakeholder groups and accompanying activity systems that it needed to intentionally engage, including agro-processors, suppliers of agricultural tools, consumer groups, funding partners, research organizations, universities, and colleges (see the Figure). The second model solution was the identification and adoption of the International Federation for Organic Agriculture Movements’ Participatory Guarantee System, which would enable the local organic farming community to set, implement, monitor, and certify local organic production using agreed-upon criteria. The Green Growers Association recruited organic inspectors and an information technologies specialist to adapt international organic farming standards, communication, and marketing.

While the above process helped the Durban organic agriculture community learn jointly and generate solutions to agricultural challenges, it also revealed that organic trainers and mentors needed higher order skills to perform their tasks. In addition, the study concluded that agricultural cognition comprised not just the knowledge of trainers, but also of farmers, farmworkers, inspectors, and marketers, which should be drawn on and developed (Mukute, 2010). Finally, it recommended the formation of local, lasting collective learning, innovation, and action structures. These insights were shared with the South African Qualifications Authority and Rhodes University, which influence education policy in South Africa. The insights and recommendations demonstrate a link between local and national level learning processes, which could strengthen environmental education impacts across multiple scales.

Knowledge-sharing practices in community home-based care, South Africa

Community home-based care in South Africa is in high demand due to the HIV/AIDS pandemic and related diseases, resulting in waste that poses a public health risk if not disposed of correctly. Typically, healthcare waste includes swabs, adult diapers, and used dressings, needles, and surgical gloves. Young children have been seen playing with surgical gloves found dumped on a vacant plot, inflating them, filling them with water, and drinking out of them.

Different community players contribute toward achieving sustainable healthcare waste management. Some partners enforce waste management regulations, some produce healthcare waste, while others sort, manage, and dispose of it. Cultural historical activity theory sees these players as interacting in activity systems that are dynamic and multi-voiced, and as individuals whose ideas and practices can be transformed through ongoing dialogue in expansive learning processes.

Research revealed that problematic waste management practices in home-based care facilities were linked to limited knowledge and knowledge-sharing (Masilela, 2015). It became clear that environmental education processes were needed to strengthen environmental management practices. For example, healthcare waste is commonly disposed of in domestic waste bins or illegally burned, but environmental health officers lack knowledge about such practices. Similarly, community home-based caregivers, despite extensive experience in nursing and palliative care, did not know how to dispose of waste generated outside of a clinic. Although senior managers seem to hold more detailed knowledge about healthcare waste management, channels to disseminate this knowledge to environmental health officers or community home-based caregivers were non-existent. The result: impoverished waste-pickers rummaging through piles of domestic garbage in search of items to recycle or resell faced risks of encountering healthcare waste.

Three workshops provided the basic framework for an expansive learning process in which the managers of home-based care facilities, environmental health officers, and waste inspectors identified their strengths and weaknesses and collaborated to seek long-term solutions. The voices of waste-pickers and caregivers were brought into the workshops through interview transcripts and photographs, enabling stakeholders to develop a richer perspective on the complexity and contestation of the problem. The workshops created opportunities for people with diverse skills and backgrounds to build common knowledge and develop new practices around a shared outcome (i.e., improving waste management). Participants learned about daily practices related to healthcare waste management (“who does what”); gained insight into tensions and contradictions; and asked “why,” “how,” “where,” and “what” questions to clarify misconceptions.

The healthcare waste management activity system suggests lessons for community environmental education more broadly. Environmental sustainability challenges in urban settings require collaboration among multiple players who need access to contextually relevant knowledge. Processes that stimulate dialogue and the production, circulation, and reflexive critique of knowledge within and across activity systems, such as the workshops addressing healthcare waste management, create opportunities for expansive learning leading to sustainability innovations.

Conclusion

The communities of practice framework allows us to examine social learning that occurs through participation in a community focused on a common enterprise. Cultural historical activity theory enables us to see how activities expand through encountering challenges or contradictions, resulting in learning at higher levels.

Communities of practice and cultural historical activity theory are two social learning frameworks useful in understanding community environmental education.

A focus on learning through interactions also suggests equitable knowledge sharing, which is important to urban environmental education. It reveals a subtle change in perspective from expanding existing outreach programs to be more inclusive of non-traditional audiences, such as low-income youth, farmers, or community healthcare workers. Instead, youth, farmers, and healthcare workers, alongside university scientists and professional environmental educators, all have knowledge to bring to the table. Recognizing and honoring each actor’s assets not only uncovers ideas potentially useful in addressing sustainability issues, but also empowers less powerful community members. For these reasons, it is a critical component of social learning and of urban environmental education that seeks to foster community wellness.

Preserving Urban Nature, No Silver Bullets

Many voices. Greener cities. Better cities.
Any urban greenspace without a “friends group” and cadre of stewards faces an uncertain future. Guerrilla action may be necessary.
There is seldom a “silver bullet”, single pathway to success when it comes to protecting urban greenspaces. Multiple strategies, often modified, sometimes abandoned, are typically the only way grassroots-based urban conservation efforts succeed in the face of bureaucratic resistance. Efforts to preserve and restore a 160-acre wetland in the Willamette River floodplain near downtown Portland, Oregon is a classic case study of a “by any means necessary”, decades-long campaign to protect what would become Portland’s first official urban wildlife refuge.

In the fall of 1970 I was sitting in a mammalogy seminar at Portland State University where I was a teaching assistant in the university’s biology department when Al Miller, a gangly, be-spectacled volunteer with the local Audubon chapter walked into the room hoping rope some naïve young biologists in the running battle between the city parks department and local conservationists to protect a neighborhood wetland.

Soon thereafter I found myself sitting in stuffy, cramped Audubon library hammering out letters to the city on an old Underwood manual typewriter, the sort where keys stick together every few strokes. That I had never set foot in Oaks Bottom was irrelevant. Our recruiter’s passionate pitch, combined with the fact that he had worked for the state fish and wildlife agency and was an Audubon emissary, was good enough for me. Trust among co-conspirators is an essential ingredient for success.

Twelve years as Audubon’s Urban Naturalist my first assignment was a resurrection of the campaign to save Oaks Bottom. The challenge by then was more about benign neglect than by earlier plans to fill the wetland for a motocross course, children’s museum, and “walk of heroes.” City parks were still resistant to designating the wetlands as a wildlife refuge, something for which the local neighborhood association, Audubon, Sierra Club, The Nature Conservancy, and local outdoor writer had long lobbied.

It’s a Sign!

Such sustained recalcitrance demanded new, more direct action tactics. If the city would not act, we would. A sympathetic state fish and wildlife biologist was an early ally in what would be a prolonged campaign to secure the wetland’s permanent protection. Joe, the biologist, supplied us with official “wildlife refuge” signs. They were intensely bright, highly visible yellow plastic signs that would be visible from great distances. To avoid implicating the biologist, I sheared off the reference to the agency, created a stencil and spray painted “City Park”, creating a passably official looking sign that read, Wildlife Refuge, City Park.

With forty brilliantly lettered signs in tow my side-kick Jimbo Beckmann (image 6) and I toted a twelve-foot ladder, hammer, nails and, armed with a bottle of Jim Beam bourbon proceeded to nail up the signs around the wetland perimeter, thereby establishing, by fiat, that we unilaterally declared the city’s first urban wildlife refuge. Amazingly, in a short two weeks our local newspaper, The Oregonian, ran an unrelated story that a deceased person that had been found in…Oaks Bottom Wildlife Refuge. Not the publicity we sought, but the first-ever public recognition of the wetland’s new, guerrilla-ordained status was fine with us. From that point onward the media routinely referred to the wetland, which formerly it had derisively labeled a “bottomland swamp”, as Oaks Bottom Wildlife Refuge. Progress.

Rewriting history

If you want to change public policy, sometimes hearing it from officialdom is the surest, quickest route. Later that same year a city official was to give a speech commemorating the dedication of Audubon’s new Wildlife Care Center. Having worked with city staff I for some time I was on friendly enough terms that I was shown the prepared text. I asked if it would be possible to alter the text…just a tad….to insert an insignificant reference to “Oaks Bottom Wildlife Refuge.” The staffer, seeing no harm in making such a small change, agreed. Later that morning came the first formal reference to the wetland’s refuge status from a prominent elected official. Progress.

Any urban greenspace without a “friends group” and cadre of stewards faces an uncertain future. What can be done today can be undone tomorrow, through neglect or development pressure. We needed to create a movement of grassroots activists. I went to Martha Gannett, a graphic artist and Audubon volunteer, who created colorful Bottom Watchers t-shirts (image 8) with two colorful kingfishers keeping watch over the bottoms. Voila, we launched the Bottom Watchers and Friends of Oaks Bottom. With an organized group of volunteers, we reached out to the park’s volunteer coordinator and started annual clean-ups and trail maintenance crews. The Youth Conservation Corps had created an unpaved, two-mile loop trail in the early 1970s which was soon overrun with a prickly, impenetrable wall of Himalayan blackberry. The bottoms has also become a favored location for pickups to lose tons of household garbage, construction debris, and decaying animal carcasses. An annual garbage haul was instituted and signage…official this time…helped staunch the flow of garbage into the bottoms.

Getting formal

By the late 1980s, the time had come to (mainly) drop the guerrilla tactics and get more formal status from city bureaucrats. Formalization came by way of writing a wetland management plan. Working with Portland Parks and Recreation’s natural resource staff and the local Soil and Water Conservation District two other advocates, one an EPA wetland ecologist the other a local high school science teacher and I drafted an Oaks Bottom Wildlife Refuge Management Plan, which was promptly adopted by City Council. This came eighteen years after Al Miller’s recruiting gambit and going on thirty years earlier game, but ultimately unsuccessful, efforts. It’s no wonder I adopted another conservations motto of endless pressure, endlessly applied as my own. That mantra speaks to one of the most frequent paths to success…dogged determination.

Once the Master Plan was adopted, we were on the road to permanent protection of the wetland as the city’s first official urban wildlife refuge. However, we quickly learned a plan without funding is a hollow victory. Next came intense battles over the bureau’s natural area budget, which was perennially underfunded even though eighty-five percent of the city’s 10,000-acre portfolio were habitat parks. Once we secured additional park funding and engaged another bureau with a more robust ecological staff, the city initiated ongoing restoration efforts to manage the bottoms with an emphasis on ecological function. Public access was controlled by retention of an unpaved perimeter path while a new “rails with trails” regional path provided unfettered access on the wetland’s western edge.

Over the past twenty years, professional ecologists with Portland Parks and the city’s Bureau of Environmental Services have removed blackberry, English ivy, and other invasive species and replanted with native species. Formal interpretive signs have replaced the now disintegrated signs Jimbo and I posted over three decades ago. A massive habitat restoration plan is in the works which will re-connect the bottoms’ floodplain with the adjacent Willamette River to enhance salmonid habitat.

Art and nature

My most recent, and probably last major effort to focus public attention on the importance of Oaks Bottom to the city’s commitment to protecting urban biodiversity and providing nature nearby was the creation of what I believe is the largest hand-painted wall mural on a building in the country. This effort grew from a 1986 project with our then mayor, Bud Clark and local muralist Mark Bennett of ArtFX. Bud and I worked to declare the Great Blue Heron Portland’s official city bird, and Mark created a huge heron mural on a building overlooking Oaks Bottom. Twenty years later Mark called me and asked when we were going to finish off the entire building, the Portland Memorial Mausoleum.

The result is 55,000 square foot mosaic depicting birds and other wetland denizens. The mural is visible from across the Willamette River, more than a mile distant. Just another way to celebrate nature in the city and draw the attention of thousands of cyclists, walker, and joggers who use the regional greenway trail at the wetland’s western edge.

While Oaks Bottom is a singular story capturing the need to engage in a “by any means necessary” approach to urban conservation, there are myriad other stories, locally, nationally and internationally, all spearheaded by creative urban greenspace advocates each providing inspiring tales of preserving nature in the city, thereby contributing to the nature of cities. The Nature of Cities is dedicated to telling those stories.

Proposals for the Environment and the Future of Cities

Many voices. Greener cities. Better cities.
While the suburban mega city is largely the product of unbridled real estate speculation, their existence establishes a new starting point for urban design—hopefully one that produces cities by nature.
A Brief History of Climate Change

Issued in November of 2018 by a collection of 13 government agencies known as the U.S. Global Change Research Program, the environmental assessments of The Fourth National Climate Assessment (NCA4) present a deeply disturbing forecast and polarizing confrontation to most anyone reading the report.

“Disturbing”, given the grave assessments and the magnitude and nature of the anticipated climate events and their impact to the human condition and natural life of the earth. “Polarizing”, in that the report confronts virtually every individual who reads the 500-some page document, especially those in design-related disciplines, and environmental fields, to make a fundamental choice.  One, change how one personally lives, works and the content and expertise they advocate through their work. Or two, ignore the report and go on with one’s life and business.

The environmental forecast is dire.

Sea levels are already about a foot higher around US continental shores. Heat waves are increasing and more are predicted. Unusually long droughts are already happening and more of these are predicted and expected to unfold at accelerating rates. The same is forecasted for wildfires. The last three consecutive years have been the warmest years on the measurable record for the globe. The last five consecutive years have been the warmest ever recorded at the polar ice caps.

When first encountered by explorers in 1850, Glacier National Park had 150 distinct glaciers. Today, only 26 remain. Experts are already suggesting that Miami will become “unlivable in the future” not only because of low-level flooding, but also due to salt contamination of the Okeechobee fresh water lake where it draws water.

While I unfortunately can’t claim to possess fantastical abilities to tell the future or conjure  a crystal ball for a topic that is unquestionably overwhelming and comprehensive, the following article offers a set of realistic proposals to embolden the work of landscape architects, architects, designers, policy-makers and environmentalists. In response to the ever-present question, “What can I do as an individual?” each topic was selected because of the potential it offers to individuals to make a difference. 

Topic One:  Vitamin N

Health should always be the number one priority and objective that guides city planning, building orientation and their design, to paraphrase the Roman architect Vitruvius in his multi-volume treatise on architecture, “De Architectura” written in the 1stcentury AD. It’s challenging, if not difficult to comprehend how advice taken from a 2,000-year-old document, could be relevant today, given the extraordinary advances in technology and human population.  However, a simple diagram puts the challenge and issue of health into a new kind of perspective and unlocks a new awareness about health and the status quo.

The diagram above illustrates the 2.5 million years that encompass the evolution of humanity. The thin magenta line on the right is more than ample thickness to represent the entire amount of time where the physical backdrop to life that has shaped  the human condition has been life spent living in organized settlements, villages and cities. The 150-year era of  anthropogenic climate change would fit into an even thinner, microscopic slice of the same line.

It might seem like this diagram is a graphic trick to arouse alarm about the rapidity of climate change and how, if it persists to become a more measurable width on this diagram, it would probably mean the end of human civilization. However, the actual point of the diagram is to call attention to the time and the entire area to the left of the right edge, and a particular realization it unlocks about health and human development.

As the legendary biologist Dr. E.O Wilson of Harvard characterizes, for approximately two and half million years, “Humanity was a biological species living in a biological environment.”  While most everyone loves the cold medicine and indoor plumbing of the modern world, thirty-some years of credible, peer-reviewed research by individuals such as Dr. Wilson and Dr. Ming ( Frances ) Kuo of the University of Illinois, along with other colleagues of a like-mind, are revealing that human contact with nature produces extraordinary health and human welfare benefits, as follows.

According to studies taken from the Chicago Police and Crime reports, individuals living in public housing projects, where the “housing projects” were cookie cut buildings, people living in the buildings that were surrounded by more trees and nature – “greener in other words” – produced fewer violent crimes and fights. In the greener buildings, when altercations and disputes arose they were less likely to be settled with violence.

Further studies with children who suffer from ADHD and depression, revealed that, when in a controlled test group, children experienced a daily twenty minute walk in a park, another group a residential street with no trees, and a third group in an urban downtown, the children who experienced the park saw a reduction of their symptoms and a higher ability to concentrate than the other two groups whose symptoms were actually amplified by the nature-deficient environments.

Physical, biological and cardiovascular health is also measurably affected by contact with nature. Controlled studies of individuals who were instructed to take “a walk in the woods” developed a healthier cardiovascular blood profile than those who did not. Blood pressure lowered and, astonishingly, blood chemistry altered toward a healthier biochemistry.  The health benefits continue.

Individuals who lived in greener neighborhoods also demonstrated a higher ability to survive a stroke, if one happens. As Dr. Kuo has come to summarize, “Nature appears to be a new kind of vitamin” that cultivates cardiovascular health and cardiovascular resilience in humans.

Even a basic question of how much “nature” does one need before measurable benefits appear, reveals that even shorter, periodic “doses of nature” during just a three day weekend trip to a natural area, elevates the production of antibodies and blood chemistry that is beneficial to fighting the advent of cancer cells, an astonishing 50 percent. One month after the three-day weekend with nature, blood tests of the same individuals reveal that blood chemistry is still 28% above where it was before the trip.

The old saying to “stop and smell the roses” portended that actually doing so can improve your health. Thirty-year long studies show that smelling roses (and other flowers that are fragrant to humans) reduces the release of stress and obesity-producing cortisol.

Taken together, along with many other studies with similar results, that  “green nature-focused neighborhoods” (and buildings by logical extension) reduce the number of preventable deaths from cardiovascular disease and diabetes, by one half.

Considering that cardiovascular disease cost the US Health Care System over

$500 billion dollars in 2016, and the costs of diabetes related to cardiovascular disease cost were $245 billion dollars, a new Health Imperative for architecture, landscape architecture and environmental design may be coming of age and toward a new purpose with unassailable and measurable results.

To extend the original axiom from Vitruvius, “health” can apply not only to buildings and arranging cities and a physical environment that is healthy to humans, but also how the cities and buildings we arrange reverberate health and healing to a planet that is groaning with the symptoms of Climate Change.

This leads to ReWILDING, which is the next topic. 

Topic Two: REWILDING

ReWILDING is a process and an approach to landscape and environmental development that begins by constructing an inventory of the species and natural life that the landscape can shelter, that is also appropriate to the place. Architects, who typically design buildings that are tailored to a similar inventory of occupants, refer to this formative activity as “the program” of a building.

What is known as ReWILDing began some thirty years ago as environmental reconstruction that was intended to rebalance ecosystems through the re-introduction of species, largely alpha predators such as the grey wolf project in Yellowstone and also species that repopulated African preserves and the surrounding savannahs.

The idea that ReWILDING can apply to virtually any landscape project, at any scale as a new programmatic imperative for the landscape of any project or building program, is sweeping the world.  The key to understanding the application of ReWILDING as a design activity, is to recognize that all projects and sites are not appropriate environments for all the possible species a region might offer for consideration.

For example, where the left-over landscape around a suburban motor bank isn’t possible to ReWILD for coyotes, red fox and the bobcats that freely roam the watershed corridors in Dallas Fort Worth, a small landscape project like this still can, successfully ReWILD for native bees, pollinators, migratory songbirds and, if storm detention is involved, aquatic plants and the amphibians and species they support.

Egrets in Dallas

With ReWILDING, almost every new project, site renovation or construction can, to some degree, also be an act of environmental recovery. Once the program of natural species is established, plant communities and arrangements take place accordingly.

The final step in the process is to reintroduce human activity into the ReWILDED landscape, carefully with design, so the two conditions can co-exist.

Topic Three: City by Nature

Cities that flourished in the mid to late twentieth century such as Phoenix, Dallas / Fort Worth, Houston, Austin and Atlanta, all materialized as thinly arrayed patterns that were enabled by the motor car, cheap energy and an environmentally unbridled and unconstrained culture.  While pre-twentieth century cities largely formed around densely urban, colonial cores that generated cultural densities (between 30 persons per acre in San Francisco to over one hundred persons per acre in Manhattan), the endless landscape of the suburban megacities average around one person per acre.

An unintended effect of suburban megacities is the appearance of wildlife inside city limits that thrive in an abundant geography of open areas and the ribbons of trees and nature that exist along metropolitan creeks, rivers and ravines of a cities watershed network. While cities have always had “pests” such as rats, fleas, lice and other vermin, the appearance of coyotes, red foxes, turkey flocks, bobcats and nesting eagles are all species that are presently thriving within the Dallas Fort Worth Metroplex, where my private practice works and studies. DFW is a textbook demonstration of solutions and possibilities that can transfer and apply to cities with similar problems and opportunities.

Downtown Dallas Trinity River Corridor

Settled on the gently rolling topography of the North Texas Blackland Prairie, Dallas Fort Worth (DFW ) is traversed by a vast, web-like watershed network of small rivers, creeks, ravines, tree belts and man-made ponds and reservoirs, that some experts might refer to as the Green Infrastructure of the city.  Areas such as the luxurious Turtle Creek corridor in Highland Park, Dallas and the historic White Rock Lake reservoir demonstrate how urban planning can leverage a cultural affinity for nature to form neighborhoods of exceptional economic and cultural value around the nature of these kind of resources.

The DFW Branch Waters Network is an emerging planning initiative to make the ad hoc process of development that is forming along the green corridors of the watershed network a more deliberate process with predictable results.

Vitruvian Park Drone View

Such an initiative is reinforced by the health benefits of nature, the cultural affinity for nature which attracts density patterns, the connectivity of the watershed nature for recreation and transportation and all the attendant economic benefits and value that could arise, that taken together, could compel suburban mega cities to restructure in potentially, the same number of decades it took to originally produce the unsustainable, endless and sprawling form.

While the suburban mega city is largely the product of unbridled real estate speculation, their existence establishes a new starting point for urban design.

Intersecting these needs with a cultural affinity for nature offers the potential to eventually produce cities by nature, that offer health for the human condition and the environment of the planet, delight and a new kind of prosperity that will not be at the expense of the earth and ourselves.

SUMMARY: Energy, The Common Denominator 

According to the 2005 bestselling book “The Tree” by Colin Tudge, wood will be the building material of the future. Tudge’s assertion is not based on his affinity for wood, but rather, an assertion that is entirely based on energy. Wood requires the least amount of energy for its production, given that natural energy of the sun. Depending on how it will be harvested and milled, it is a material that has the lower latent energy that is possible. Finally, wood naturally recycles into the earth through biodegradation.

Spain Metropol Parasol

Imagine how the professional design awards would change if criteria principals weren’t only aesthetics, concepts and artistic conceits, but rather were based on a new set of criteria:

  • Energy use – what projects use the least amount of energy to construct, operate, and sustain and/or to eventually demolish.
  • Human health – the health benefits the building or project engenders in the inhabitants through contact with vitamin N – or nature.
  • Ecological conservation – the depth and magnitude of the non-human species a building or a new project site and landscape accommodates and the amount of domestic water use the project preserves.

Given the clear-eyed and disturbing picture painted by the recent The Fourth National Climate Assessment,the path forward demands that the look and style of something may not be as important as the impact it makes and the healing it offers to the environment and human condition.

Where popular culture has many issues and layers that perhaps separate individuals from truly comprehending the gravitas of the situation, landscape architects and the environmental sciences are on the front lines and ready to take action.  We are in a unique position to make an immediate and measurable difference.

Art BioFarm

“Form follows performance” may replace the industrial preoccupation of the twentieth century and its priority for “function” that is damaging to the environment. It will take the effort of many, if not everyone’s, hands to get a grip on all the solutions that are needed. It is a purpose and priority on which all should agree.

The work of any and every landscape architect can contribute the next granular improvement to the environment, and that improvement will aggregate with the other granular good works of others to eventually accumulate results.

As one example, in Dallas Fort Worth, if one in every ten households installed a 5 x 5 ReWILDED pocket prairie in their back yard, 1,000 acres of the original Blackland Prairie could be recovered. Even for most commissions that stipulate a cultivated landscape design, edges and fringes always exist in most situations to introduce concentrations of native species that could give respites to migrating pollinators and songbirds.

Potentially of equal or greater importance, is for landscape architects to become advocates and explicators of the environment through writing, speaking and producing videos shorts. Landscape architects are one of the very few professional groups that exist, uniquely educated to understand, predict the consequences, and propose realistic solutions for the climate crisis.

Local newspapers, reeling under the impact of blogs and the Internet, are in need for volunteer writers and ideas and topics worth circulating. Reach out and ask to become a voice in your community newspapers and write for the environment. Community, school and church groups frequently struggle to convene interesting programs for their membership. Reach out and volunteer to give a lively and memorable presentation on the virtues of the landscape architecture you love and the profound ability it has, if redirected in purpose, to affect them individually and the climate crisis positively, and with beauty.

Moreover, landscape architects should learn and then be unhesitant about developing their skills in persuasion, of linking the good intentions of ReWILDING with the superior economic advantages that it often produces.  While it’s desirable to bring a larger culture along to a more informed environmental position, in the day-to-day activities, gaining approval of a good idea, even if the basis for preference is cheaper cost and a better bottom line, is the real objective. The environment that needs the solutions and the wild life in search of habitat has little awareness for how their needs are met.

Activities and opportunities like this will often go uncompensated, although not unrecognized. Return on the effort and time it takes to prepare often materializes as another invitation for commissions that align with a landscape architects interest.

In imprecating artists to be leaders, the late sculptor Isamu Noguchi offered remarks that should embolden most landscape architects and planners to act. To paraphrase, “No one is going to pay you in the beginning. Instead, convince yourself and then go out and convince the world what it needs by leading with your unassailable and good intentions, and then, they will know how and why they need to hire you for what’s next.”

On The Nature of Cities

Prospective Urbanism—Using Science and Fiction to Imagine a New Way for Urban Nature

Many voices. Greener cities. Better cities.

Une version en français apparaît immédiatement après la version portugaise.

Designing nature is a challenging task in an urban environment. For example, how can a 38 years old individual (myself) safely edit a 3.8 billion years old system (Nature)? It is quite a test for creative confidence. An arrogance, really.

I remember when I began studying landscape architecture and struggled with the blank page. Twenty years later there is no longer a blank page. Instead, I am challenged by a world of millions of individuals and trillions of interrelations; a never ending border between our knowledge and the regenerative possibilities of nature.

Scales of time, nature and culture

Biodiversity is the greatest value a territory can offer to a human community. Most cities ignore biodiversity.

Why do we create cities this way?

What were the dreams of the generation that drew our cities in this way?

What city do we want?

In what kind of city can we live today?

In what kind of city can we dream?

These are a lot of questions! And in our era of certainty, we may need more questions than answers. I used to work with technical and aesthetic solutions to improve social and ecological performances of territories and ecosystems. However, I think that cultural change in a society can have higher and quicker positive impact than transforming land use or land cover. We may need to change our culture to change the way we develop and conserve our earth and its cities.

This blog is aimed to be a provocation, a utopian design to promote a debate about the place of nature in cities. I used to say that when you ask something for nature you should ask for twice as much, since our society is a fierce negotiator. The proposal is about creating new and audacious layers for the city, building aerial cores of biodiversity and link them to create new usage of the aerial space what is actually the space that is remaining for nature in the middle of the city, something high (including different meanings of the term).

Not writing but reading

In this essay I will try to give a personal and not definitive answer to a few of the questions above. So, first of all, I will to do more of the same—mais do mesmo, a Brazilian expression for when you are not doing something new. It is the way nature works: more and the same, but improved.

I will keep the idea of doing something local, even more local in fact. I will stand at my bedroom window, and start to take a look at my city’s nature and just keep watching. Let us read nature.

It looks like a great occupation.

I am looking at a public nature. It is the eastern part of Tijuca National Park, and it is actually bigger than public: it is a world heritage cultural landscape. It is the first time an urban landscape has been included in this list and I understand it as an appeal for more protection and conservation of this scenic landscape of tropical Atlantic rainforest, granitic hills …and a lot of concrete occupying most of the lowlands.

Personally, I have my doubts if God is Brazilian as many say, but I am sure that Biodiversity is Brazilian. It lives here, and this country is its temple. There is proof of it. It can be found in biodiversity indices about Brazilian Biomes and species, making Brazil not only a soccer world champion but also a biodiversity world champion.

The neighborhood we are watching in the above picture is called Humaitá. According to the etymologist Machado, the meaning is derived from the Tupi “mbaitá”, meaning a small parrot. Today we place this bird, smaller than a parrot, in the family Psittacidae, and the common name is maitaca or maritaca. You can see pictures and its typical song here. They used to fly through the city at the beginning and at the end of the day, in small groups, making during the flight a typical sound of the city. So as the name of the district says Humaitá: the place of the maitacas.

Is reading an inventory?

When Carolus Linnaeus denominated and “taxonomized” our species as Homo sapiens in 1758 in Systema Naturae, we were in the middle of the Siècle de Lumières, the major scientific revolution that occurred in the human history.

Science, art and design were at this time integrated, in part because it used to be more common for people to practice ALL THREE at once. Now they have become separate, and urban design has weakened because of it. And urban nature is abused because of it. How can they be reintegrated for the good of urban spaces, both as places of nature and as human settlements?

Let’s look outside and see what nature teaches us, what she shows us that Works (and doesn’t work).

Let’s learn from this to design better.

So, how should we read nature, especially in the context of reintegrating science with design? Nature is movement, nature is dynamic, so we may use dynamic tool to read it. I am fascinated by time lapse photography, a visual sequencing through a fixed frame rate permitting to see natural movements by changing our vision, our dimension of the fourth dimension of time.

This observation absolutely inspires this proposal, as the dynamic movement of this aerial cloud dance here suggests directly to use the aerial space of the city. It is important to watch this video of around one minute to understand better the origin of the proposal.

Think in four dimensions

When we talk about space we commonly use four dimension parameters. In computer aided design (CAD) software, the X and Y axis are quite similar and define planarity and are the most used dimensions in design and representation of our planet, our communities and our habitats. Z, the vertical axis is the axis of the gravity, it is one of the factor that has shaped and continues shaping the forms of our species and environment, most cycles use its force to promote movements and changes.

Time is the fourth dimension, the dimensional system of actions, interactions and results. Each dimension should have the same importance as the others when analyzing and planning spaces and places.

Fight for space

Spatial competition is an ecological interaction between species in the environment since life exists. Today the “best” competitor for space is the human species, with a massive territorial sprawling of agriculture, deforestation, reforestation, mining, cities and their many infrastructures, which generate not only land cover change but also chemical and thermal change of our environments (Living Planet Report 2012).

We have succeeded to giving our name to the next geological era, the Anthropocene. The world is ours, and in a bad way. The proposal drawn for Humaitá, the maitaca´s district is conceptually based on principle of equal rights: equal rights for plants, insects, animals and humans (Michael Marder, The time is ripe for plant rights). Rights for space and place are included in the proposal and offer the nutrient for the utopia of designing a nature for the city.

Thinking about more nature, or places for more nature in a city where there are not even places for people to walk in the street is very difficult. Potential areas are shrinking quickly — selling public areas to the private real estate sector is common in Rio. The district is a mix of old villas, old houses, some mansions, and new 10 to 20 story residential buildings popping on top of the other categories.

The official site of urban data of the city hall about the district reveals an astonishing number about vegetation in public parks (2001): 0%. There must be an explanation for why we have zero-tree public parks in the city, but it gives the taste of the environment many experience in the urbanized area of the city of Rio de Janeiro.

Change culture like ecological succession

Ecological restoration is based on a range of concepts, one of them is ecological succession, the process by which the species of an ecosystem change over time and the restorative efforts that may required for the creation of environmental conditions for natural successional processes to be activated. But the concept of this essay is to think about a cultural succession, a way to imagine the city. Our city nowadays is not so far from the vision of the Fritz Lang’s ‘Metropolis’ or Ridley Scott’s ‘Blade Runner’ in terms of overanthropized spaces. Science Fiction is a great philosophical device to discuss new forms of nature for urban environment. And it may save many human habitats in Humaitá if we really think of equal rights for space.

Natural structures: cores and flows

Island biogeography is one of the main theories of landscape ecology and is a tool for debate in reserve design and other discussions about nature conservancy and design. Here I intend to promote “nature science fiction”, so it will slip a little bit from plausibility and deviate from literal technical and feasibility “details” (purists forgive me, please). And it will draw a utopian proposal for nature in the Humaitá neighborhood, thinking about core and flows as a framework for design.

The idea of creating a radical biodiversity island is not new, Gilles Clément, has done it in its île Derborence in the Parc Matisse, in Lille, France, creating an untouchable part of nature in the middle of an urban planning: 3500 square meters of native mixed stratus of vegetation, 7 meters higher than the common level. The design is a direct reference to one of the few primary forests in Europe located in the Valais (Switzerland).

The main idea of the proposal for Humaitá is to create a new layer above the city in its aerial space, with different types of connections for adventurous fauna, flora and people.

Between clouds and rivers

Water is a fascinating dynamic compound of nature and it is vital for all forms of life. The time lapse observation of the forest creating clouds and receiving rain show us a natural beauty that you cannot see when you are walking in the middle of a polluted flooded street during rush hour. Rain is a true beauty, a source of life and our cities succeed to transform these moments in an urban nightmare. Like every form of life, we are part of the water system, but now there are major negative impacts in the different scales of the water environment of our blue planet. Should offsetting water cycle from human relation be safest for it? For sure it is a polemical idea, but given that we have succeeded to change the chemistry of most of the water on the surface of earth, it is not so radical. Using gravity we can make water pass through suspended gardens and so may think about suspended wetlands to stock water and create habitats for avifauna in the sky.

Social scale, ecology and dynamics

In my opinion, the positive scales for the Human species are the individual and the community scales. Cities in a certain way change the scale of our communities to landscape scale, regional scale and macro scale. If we look at our neighborhood and the social tissues of it through landscape ecology methodologies we might find fragmentations, edge effects and so much more ecological phenomena. Ecological Thinking may be the new holistic approach into all disciplines, not only for biology and earth science.

When you live in Rio de Janeiro, moving from one place to another is a concern — the city has grown but the streets do not get larger. The last brilliant idea of the government was to promote individual motorized transport: the car. So as transport is both a relationship and a flow, the proposal creates suspended pathways and zip-lines between the hills to connect buildings, public spaces, public equipment, schools, slums and natural areas. I think this system creates a richer environment not only for nature, but also for humans.

Utopia and reality considerations

I hope this proposal will generate debates and instigate more utopias. For sure many points have not been deeply developed and there is some considerations about integrity of ecosystems, but this proposal is meant to be provocative and novel, creating new communities around new relationships.

Everybody may be concerned by plants falling on the top of their head, but as we already throw a lot of concrete on top of swamps, rivers and forest it is a hard lex talionis logic, an eye for an eye. For safety, don’t try to do this at home, but please dream of new forms of nature for our cities

Urbanismo Prospectivo—Usando a Ciência e a Ficção para Imaginar uma Nova Natureza Urbana

Escalas da natureza, tempo e cultura

Projetar a natureza é uma tarefa difícil em um ambiente urbano. Por exemplo, como um indivíduo de 38 anos (eu) pode de maneira segura editar um sistema de 3,8 bilhões de anos (Natureza)? É um bom teste para a confiança criativa, uma arrogância, na verdade.

Eu me lembro quando eu comecei a estudar a arquitetura da paisagem, lutando com a página em branco e passando dificuldades com ela. Vinte anos depois, não há mais nenhuma página em branco, agora eu sou desafiado por um mundo de milhões de indivíduos e trilhões de inter-relações, uma borda sem fim entre o nosso conhecimento e as possibilidades de regeneração da natureza.

A biodiversidade é o maior valor que um território pode oferecer a uma comunidade humana. A maioria das cidades ignoram a biodiversidade.

Por que criamos as cidades dessa maneira?

Qual eram os sonhos da geração que desenhou nossas cidades dessa maneira?

Que cidade queremos?

Em que tipo de cidade podemos viver hoje?

Que tipo de cidade podemos sonhar?

Quantas perguntas! Na nossa era de certezas talvez precisamos mais de perguntas do que respostas? Eu uso no meu ofício de paisagista soluções técnicas e estéticas para melhorar as performances sociais e ecológicas de territórios e ecossistemas, mas percebo que a mudança cultural de uma sociedade pode ter um impacto maior e mais rápido do que a positiva transformação do uso ou da cobertura do solo. Talvez seja necessário mudar a nossa cultura para mudar a forma como desenvolver e conservar as nossas terras e as suas cidades. A proposta ora apresentada é uma provocação, um projeto utópico para promover um debate sobre o lugar da natureza nas cidades. Costumo dizer que quando você pede algo para a natureza, você deve pedir em dobro já que a nossa sociedade é muito dura nas suas negociações com ela. A proposta consiste em criar novas e audaciosas camadas para a cidade, pela construção de núcleos aéreos de biodiversidade e ligar eles criando um novo uso do espaço aéreo, que é realmente o espaço que resta para a natureza no meio da cidade, algo alto (incluindo os diferentes significados do termo).

Ler e não escrever

Vou tentar dar uma resposta pessoal e não definitiva para algumas dessas perguntas nesse blog. Então, antes de tudo, eu decidi fazer “mais do mesmo” (artigo anterior). É a maneira que a natureza trabalha, mais e melhor.

Vou manter a idéia de fazer algo local, e dessa vez ainda mais local. Vou ficar na janela do meu quarto, e vou começar a olhar a natureza da minha cidade, vou ler a natureza. Parece uma excelente ocupação.

Estou olhando para uma natureza pública. E a parte mais oriental da Parque Nacional da Tijuca, e na verdade ela é mais do que pública: é um patrimônio mundial da humanidade. É a primeira vez que uma paisagem urbana foi incluída nessa lista e eu entendo isso como um apelo para uma maior proteção e conservação desta paisagem de mata atlântica, morros de granitos … e um monte de concreto ocupando a maior parte das terras baixas. Pessoalmente, tenho minhas dúvidas se Deus é brasileiro, como muitos o dizem, mas tenho certeza de que a biodiversidade é Brasileira. Ela mora aqui, e este país é o seu templo. Há provas disso e elas estão nos índices de biodiversidade dos Biomas Brasileiros, fazendo do Brasil não só um campeão mundial de futebol, mas também o campeão mundial da biodiversidade.

Esse bairro que estamos vendo na foto acima é chamado de Humaitá.  De acordo com o etimologista Machado, o significado poderia ser derivado do tupi “mbaitá”, significando um papagaio pequeno. Hoje damos a esse pássaro, da família dos psitacídeos, o nome comum de maitaca ou maritaca. Você pode ver fotos dele e seu canto típico aqui. Eles costumam voar pela cidade no início e no final do dia, em pequenos grupos, fazendo deste vôo um som típico da cidade. Assim como o nome do bairro Humaitá diz: é o lugar das maitacas.

Ler significa inventoriar?

Quando Carolus Linnaeus denomina e “taxonomiza” a nossa espécie como Homo sapiens em 1758 no Systema Naturae, estávamos no meio do Siècle de Lumières, a maior revolução científica ocorrida na história humana. Ciência, arte e design eram integrados neste momento, em parte porque a pratica DOS TRÊS ao mesmo tempo era mais comum. Agora eles se tornaram separados, principalmente no que se remete a projeto urbano. E a natureza urbana sofre com isso. Como eles podem ser reintegrados para o bem dos espaços urbanos, tanto como locais de natureza, tanto como assentamentos humanos?

Vamos olhar para fora e ver o que a natureza nos ensina, ela nos mostrará o que funciona (e não funciona).

Vamos aprender com isso para projetar melhor.

Então, como devemos ler a natureza, especialmente no contexto de reintegração da ciência com design? A natureza é movimento, a natureza é dinâmica, portanto deveríamos usar uma ferramenta dinâmica para lê-la. Sou fascinado pela fotografia Time Lapse (intervalo de tempo), um sequenciamento visual através de uma freqüência fixa de fotos permitindo ver movimentos naturais, alterando nossa visão, nossa dimensão da quarta dimensão, o tempo. Técnica que muitos tem chamado de realidade aumentada. Esta observação dinâmica inspirou esta proposta, com o movimento dinâmico da dança das nuvens sugere diretamente para usar o espaço aéreo da nossa cidade. É importante assistir esse vídeo de um minuto para entender o resto da proposta.

Quatro dimensões

Quando falamos sobre o espaço geralmente usamos quatro parâmetros de dimensão. Em softwares ditos CAD, os eixos X e Y são bastante semelhantes e definem o plano, atualmente são as dimensões mais utilizadas no projeto e na representação do nosso planeta, das nossas comunidades e dos nossos habitats. O eixo Z, a verticalidade é o eixo da gravidade, é um dos fatores que formou e continua esculpindo as formas de nossa espécie e do nosso ambiente, a maioria dos ciclos usam sua força para promover movimentos e mudanças. O tempo é a quarta dimensão, o sistema dimensional das ações, interações e resultados. Cada dimensão deve ter a mesma importância que os outros quando analisamos e planejamos espaços e lugares.

A luta por espaço

A competição por espaço é uma interação ecológica entre as espécies no ambiente, que acontece desde que a vida existe. Hoje, o “melhor” concorrente para o espaço é a espécie humana com um enorme alastro territorial pela agricultura, desmatamento, reflorestamento, mineração, as cidades e suas infra-estruturas que geram não apenas mudanças na cobertura da terra, mas também mudanças químicas e térmicas dos nossos ambientes (Living Planet Report 2012). Conseguimos dar o nosso nome para a próxima era geológica, o Antropoceno, o mundo é nosso, e não é no bom sentido do termo. A proposta elaborada para Humaitá, o bairro das maitacas é conceitualmente baseada no princípio da igualdade de direitos. Igualdade de direitos entre as plantas, insetos, animais e seres humanos (Michael Marder. O momento é propício para os direitos das plantas). Direitos ao espaço e a um local de existência estão incluídos nessa proposta e oferece o nutriente para a utopia de se conceber uma natureza para a cidade.

Pensando re-introduzir mais natureza ou mais locais para a natureza numa cidade onde não há sequer lugar para pessoas caminhar na rua é muito difícil se for pensar de maneira tradicional. As áreas potenciais estão encolhendo rapidamente, já que a venda de áreas públicas para o setor imobiliário privado é comum para a prefeitura e o estado do Rio de Janeiro. O bairro hoje é uma mistura de casas antigas, algumas mansões, órgãos públicos e edifícios de 7 a 20 andares surgindo por cima das outras categorias. Os dados oficiais da prefeitura sobre o bairro confessam-nos surpreendentes números sobre vegetação em parques públicos (2001): 0,00%. Deve haver motivos burocráticos para explicar por que vivemos num bairro sem arvores nos parques públicos, mas dá o tom sobre o ambiente nas situações de pequena escala na área urbanizada da cidade do Rio de Janeiro.

Sucessões ecológicas de um ambiente cultural

A restauração ecológica é baseada em uma série de conceitos, um deles é a sucessão ecológica, o processo pelo qual as espécies de um ecossistema mudam ao longo do tempo e os esforços de restauração que podem ser exigidos para a criação de condições ambientais favoráveis para os processos de sucessão natural. Mas o conceito desta proposta é pensar em uma sucessão CULTURAL, uma mudança na forma de imaginar a cidade. Nossas cidades hoje em dia não estão tão longe da visão do Fritz Lang em ‘Metropolis’ ou de Ridley Scott em ‘Blade Runner’ em termos de espaços hiperantropizados. A ficção científica é um excelente dispositivo filosófico para discutir novas formas da natureza para o ambiente urbano. E vai permitir conservar habitats humanos nessa proposta aqui em Humaitá se realmente formos aplicar direitos iguais para o espaço. Dessa maneira, poderemos ocupar um lugar que não existe hoje, pelo menos de forma sólida.

Estruturas naturais: Núcleos e fluxos

A Biogeografia de Ilhas é uma das principais teorias da ecologia da paisagem e é uma ferramenta para o debate nos projetos de reservas e outras discussões sobre a conservação e o projeto da natureza. A proposta aqui pretende promover uma obra de “ficção científica natural”, um projeto cultural, por isso nos afastaremos de alguns critérios de plausibilidade e questões de viabilidade técnica (puristas, por favor, me perdoem) e será desenhada uma proposta utópica para a natureza do Humaitá pensando em núcleos e fluxos como estrutura de design numa forma literal. A idéia de criar ilhas de biodiversidade em meio urbano não é nova, Gilles Clément, tem executado uma na sua île Derborence no Parc Matisse, em Lille na França, criando um núcleo intocável de natureza no meio de um planejamento urbano, 3.500 metros quadrado de estratos mistos de vegetação nativa situados 7 metros acima do nível de uso comum. Esse projeto é uma referência direta a uma das poucas florestas primárias da Europa localizada no Valais (Suíça). A idéia principal da proposta para o Humaitá é de criar uma nova camada acima da cidade em seu espaço aéreo, com diferentes tipos de conexões para pessoas aventureiras ou não, fauna, flora, sendo que essas conexões podem ser separadas ou não. A legislação urbana do Rio considera que acima de 60m a ocupação é reduzida e, acima de 100m mais ainda, a proposta irá ocupar esses espaços aéreos.

Entre nuvens e rios

A água é um componente fascinante na dinâmica da natureza e é vital para todas as formas de vida. A observação por meio de Time Lapse da floresta criando nuvens e recebendo chuva nos mostra uma beleza natural que você não consegue ver andando no meio de uma rua inundada e poluída na hora do rush. A chuva é maravilhosa e a cidade transforma esse evento vital num transtorno de grandes proporções. Como todas as formas de vida fazemos parte do ciclo da água, mas agora estamos nos mesmo propiciando os principais impactos negativos em variadas escalas sobre ambiente do nosso planeta azul. Será que separar parte do ciclo da água dos ambientes urbanos seria mais seguro para a vitalidade dos nossos corpos hídricos? Com ​​certeza é uma idéia polêmica, mas pensando que conseguimos mudar a química da maior parte da água na superfície da Terra não é tão polêmico numa visão de igualdade de direitos para as diferentes formas de vida. Utilizando a gravidade pode se fazer a água passar pelos jardins suspensos e porque não pensar em zonas úmidas suspensas para estoque e filtração criando habitats para a avifauna no meio do céu?

Escala social, ecologia e dinâmicas

Na minha opinião, as escalas positivas da espécie humana são a escala individual e a escala comunitária. As cidades, de certa maneira, alteraram a escala de nossas comunidades para a escala da paisagem, a escala regional e macro escala. Se olhar para o nosso bairro e os tecidos sociais usando metodologias de ecologia da paisagem poderá se encontrar fragmentações, efeitos de borda e outros fenômenos típicos da ecologia. O Pensamento Ecológico pode ser uma nova abordagem holística em todas as disciplinas, e não apenas para a biologia e as ciências da terra.

Quando você vive no Rio de Janeiro, se deslocar é um problema cotidiano, a cidade cresceu verticalmente, mas as ruas não ficaram maiores. E a última idéia brilhante do governo é de promover o transporte motorizado individual: o carro, piorando o cenário urbano a curto e longo prazo. Assim como o transporte é uma relação e um fluxo, a proposta cria caminhos suspensos e tirolesas entre os morros para conectar edifícios, espaços públicos, equipamentos públicos, escolas, favelas e áreas naturais. Pensando o sistema das nuvens de biodiversidade como um lugar, não só para a natureza, mas também para o uso humano.

Utopia e considerações sobre realidade

Eu espero que esta proposta irá gerar debates e instigar outras utopias. Com certeza há algumas considerações sobre a integridade desses ecossistemas suspensos, entre outras questões. A proposta se insere num pensamento pós-ecossistemas antropizados, criando novas comunidades em torno de novos relacionamentos, um tipo de novela urbano-natural.

Todo mundo deve estar preocupado com a idéia de que uma arvore caia em cima de sua cabeça, mas como já jogaram um monte de concreto em cima de brejos, rios e florestas é uma lógica de lei do Talião, “olho por olho”. Por obvias razões de segurança não tentem fazer isso em casa, ou pelo menos pedem a ajuda de um especialista motivado, mas por favor não deixe de sonhar novas formas de natureza para as nossas cidades.

Urbanisme Prospectif – Science et Fiction pour imaginer une nouvelle Nature en Ville

Concevoir la nature est une tâche difficile dans un environnement urbain. Par exemple, comment un individu âgé de 38 ans (moi-même) peut éditer un système vieux de 3,8 milliards d’années (la Nature)? C’est un bon test pour la confiance créative, c’est presque une arrogance à la rigueur.

Je me souviens encore de mes combats avec la page blanche quand je commençais à étudier le paysage, vingt ans plus tard, il n’y a plus de page blanche. Au lieu de cela, je suis défié de manière permanente par un monde constitué de millions d’individus et de milliards d’interactions, un bord sans fin entre notre savoir et les capacités régénératives de la Nature.

Échelles de temps, nature et culture

La biodiversité est le patrimoine majeur qu’un territoire puisse offrir à une communauté humaine et la plupart de nos villes ignorent cette biodiversité.

Pourquoi avons-nous créé les villes de cette façon?

Quels étaient les rêves de la génération qui a projeté nos villes de cette façon?

Quelle ville voulons-nous?

Quel genre de ville pouvons-nous vivre aujourd’hui?

Quel genre de ville pouvons-nous rêver?

Ce sont beaucoup de questions! Et en nos temps jonchés de certitudes nous avons peut-être davantage besoin de questions que de réponses? J’ai l’habitude de travailler avec des solutions techniques et esthétiques pour améliorer les performances sociales et écologiques des territoires et des écosystèmes, mais je pense que le changement culturel d’une société peut avoir un impact plus large et plus rapide que la transformation positive de l’utilisation ou de la couverture des sols. Nous avons peut-être besoin de changer notre culture de manière à changer la façon dont nous développons et conservons notre terre et ses villes. Ce blog est destiné à être une provocation, une conception utopique pour promouvoir un débat sur la place de la nature dans les villes. J’ai l’habitude de dire que lorsque vous demandez quelque chose pour la nature, il faut en demander deux fois plus, puisque notre société est une féroce négociatrice. La proposition vise à créer de nouvelles et audacieuses couches sur la ville, en construisant des noyaux aériens de biodiversité et de les relier entre eux pour créer de nouveaux usages de l’espace aérien, ce qui aujourd’hui est réellement l’espace subsistant pour la nature au sein de la ville construite de Rio, quelque chose qui vole haut (dans tous les sens du terme).

Pas d’écriture, mais de la lecture

Dans ce court essai, je vais essayer de donner une réponse personnelle et non définitive à quelques-unes des questions ci-dessus. Alors, tout d’abord, je vais faire « mais do mesmo », une expression Brésilienne qui signifie que vous ne faites pas quelque chose de nouveau. C’est la façon dont fonctionne la nature: en faisant la même chose, sauf qu’en mieux, toujours un peu mieux.

Je vais garder l’idée de faire quelque chose de local (article antérieur), encore plus local, en fait. Je vais me pencher à la fenêtre de ma chambre, et  juste regarder. Lisons le paysage, cela semble être une bonne occupation.

C’est une Nature publique. Il s’agit de la partie la plus orientale du parc national de Tijuca, et c’est en fait plus que public: c’est un patrimoine culturel mondial. C’est la première fois qu’un paysage urbain a été classé dans cette liste et je le comprends comme un appel à une plus grande protection et conservation de ce paysage pittoresque de forêt Atlantique, de collines granitiques … et d’accumulation de béton occupant la plus grande partie des plaines côtières.

Personnellement, j’ai des doutes si Dieu est brésilien comme beaucoup le disent, mais je suis sûr que la biodiversité est brésilienne. Elle vit ici et ce pays est son temple, il ya des preuves de cela et peuvent être trouvés dans les indices de biodiversité des biomes Brésiliens et de ses espèces, faisant du Brésil non seulement un champion du monde de football, mais surtout champion du monde de la biodiversité, un patrimoine un peu plus utile.

Le quartier que nous observons dans l’image ci-dessus est appelé Humaitá. Selon l’étymologiste Machado, le sens est dérivé du Tupi “mbaitá”, qui signifie petit perroquet. Aujourd’hui, nous plaçons cet oiseau, plus petit qu’un perroquet, dans la famille des psittacidés, et son nom commun est ‘maitaca’ ou ‘maritaca’. Vous pouvez voir des photos de cette espèce et connaitre son chant typique ici. Ils ont l’habitude de voler à travers la ville en début et fin de  journée, en petits groupes, ce qui fait de leur vol un son typique de la ville. Ainsi le nom du quartier Humaitá signifie le lieu des maitacas. Une bien belle toponymie dont peu de gens connaissent l’origine.

Est-ce que la lecture est un inventaire?

Lorsque Carolus Linnaeus étiquette et « taxonomise » notre espèce comme Homo sapiens en 1758 dans son ouvrage Systema Naturae, nous étions au milieu du Siècle des Lumières, la plus grande révolution scientifique de l’histoire de l’humanité.

À l’époque la Science, l’Art et le design été intégrés, en partie parce qu’il était plus fréquent pour les personnes qui les pratiquaient de les pratiquer ensemble. Aujourd’hui, ils sont séparés et c’est un des points faibles majeur du projet de Ville, ce qui fait que la nature en milieu urbain est souvent malmenée à cause de cela. Comment ces domaines théoriques peuvent-ils être réintégrés pour le bien de l’espace urbain, à la fois comme lieu de Nature et lieu d’Humanité?

Regardons vers l’extérieur et voyons ce que la nature nous enseigne, elle nous montre déjà ce qui fonctionne (et ne fonctionne pas). Apprenons avec elle à mieux concevoir.

Alors, comment devrions-nous lire la nature, en particulier dans le contexte de la réinsertion des sciences dans la conception? La nature est mouvement, la nature est dynamique, il serait intéressant d’utiliser un outil dynamique pour la lire. Je suis fasciné par la photographie time lapse, un séquençage visuel à un taux fixe qui permet de voir les mouvements naturels en changeant notre vision, notre dimension de la quatrième dimension, le temps. Cet outil est la base de l’inspiration via le mouvement dynamique de cette danse aérienne des nuages qui suggère ici directement l’usage de l’espace aérien de cette ville tropicale si humide. Il est important de regarder cette vidéo d’environ une minute afin de mieux comprendre l’origine de la proposition.

Penser en quatre dimensions

Lorsque nous parlons de l’espace nous utilisons couramment quatre paramètres de dimensions. Dans un logiciel de CAO, les axes X et Y sont assez semblables et définisse la planéité, ce sont les dimensions les plus utilisées dans la conception et la représentation de notre planète, de nos communautés et de nos habitats. Z, l’axe vertical est l’axe de la gravité, il est l’un des facteurs qui ont façonné et continue de façonner les formes de notre espèce et de l’environnement, la plupart des cycles utilisent sa force pour favoriser les mouvements et les changements. Le temps est la quatrième dimension, le système dimensionnel des actions, des interactions et des résultats. Chaque dimension doit avoir la même importance que les autres lors de l’analyse et de la planification des espaces et des lieux.

La lutte pour l’espace

La compétition spatiale est une interaction écologique entre les espèces dans l’environnement depuis que la vie existe. Aujourd’hui, le “meilleur” compétiteur pour l’espace est l’espèce humaine, avec une expansion territoriale considérable via l’agriculture, la déforestation, le reboisement, l’exploitation minière, les villes et leurs infrastructures, qui génèrent beaucoup d’impacts non seulement sur la couverture terrestre, mais provoque aussi le changement chimique et thermique de nos environnements (Rapport Planète Vivante 2012).

Nous avons réussi à donner notre nom à la prochaine ère géologique, l’anthropocène. Le monde est à nous, dans le mauvais sens du terme. La proposition élaborée pour Humaitá, le quartier des ‘maitacas’ est conceptuellement basé sur le principe de l’égalité des droits: des droits égaux pour les plantes, les insectes, les animaux et les humains (Michael Marder. Le moment est opportun pour les droits des plantes). Droits à l’espace et à l’existence sont inclus dans la proposition et offrent l’engrais essentiel pour l’utopie de la conception d’une nature dans la ville.

Penser à plus de nature ou plus de lieux pour la nature dans une ville où il n’y a pas même d’endroits pour que les gens marchent dans la rue est très difficile. Les espaces potentiels se réduisent rapidement vu que la vente d’espaces publics au secteur immobilier est de plus en plus commune à Rio. Le quartier est aujourd’hui un mélange de vieilles villas, de maisons anciennes ou d’hotels particuliers et de nouveaux bâtiments  résidentiels de 7 à 20 étages qui surgissent sur les autres catégories.

Le site officiel des données urbaines de la Mairie révèle pour le quartier un nombre étonnant pour la végétation dans les parcs publics (2001): 0%. Il doit y avoir une explication bureaucratique pour avoir aucun arbre dans les parcs publics de la ville, mais cela donne le ton des espaces urbains à l’intérieur de la zone construite de la ville de Rio de Janeiro.

Successions écologiques d’un environnement culturel

La restauration écologique est basée sur un ensemble de concepts, l’un d’entre eux est la succession écologique, le processus par lequel les espèces d’un écosystème changent au fil du temps ainsi que les efforts de restauration pouvant être nécessaires à la création des conditions environnementales naturelles pour les processus de succession à favoriser. Mais le concept de cet essai est de penser à une succession culturelle écologique, une autre manière d’imaginer la ville. Notre ville aujourd’hui n’est pas si loin de la vision de “Metropolis”  de Fritz Lang ou de “Blade Runner” de Ridley Scott en matière d’espaces superanthropisés. La science-fiction est un excellent outil philosophique pour discuter de nouvelles formes de nature pour notre environnement urbain. Et il peut sauver de nombreux habitats humains dans Humaitá si l’on pense vraiment à appliquer l’égalité des droits pour l’espace.

Structures naturelles: noyaux et flux

La biogéographie insulaire est l’une des principales théories de l’écologie du paysage et est un outil de débat dans la conception de réserves naturelles et autres discussions sur protection de la nature et de sa conception. Ici, j’ai l’intention de promouvoir «la science-fiction naturelle”, avec donc des écarts par rapport à la plausibilité à la faisabilité des “détails” techniques (que les puristes me pardonnent), et la formulation d’une proposition utopique de la nature dans le quartier Humaitá, en pensant aux noyaux et aux flux en tant que charpente littérale de conception.

L’idée de créer une biodiversité insulaire radicale en ville n’est pas nouvelle, Gilles Clément l’a fait dans son île Derborence au Parc Matisse, à Lille, en créant un espace inaccessible de nature au milieu d’un plan urbanisme: 3.500,00 mètres carrés de végétation native en strates mixtes, à 7 mètres de hauteur du niveau d’usage commun. Le projet est une référence directe à l’une des rares forêts primaires en Europe situé dans le Valais (Suisse).

L’idée principale de la proposition pour Humaitá est de créer une nouvelle couche au-dessus de la ville dans l’espace aérien, avec différents types de connexions pour la faune, la flore et les aventureux.

Entre nuages ​​et rivières

L’eau est un composant fascinant de la dynamique naturelle et elle est vitale pour toutes les formes de vie. L’observation via Time Lapse de la forêt créant des nuages ​​ nous montre une beauté naturelle que vous ne pouvez plus voir quand nous marchons au milieu d’une rue inondée et polluée en  pleine heure de pointe. Comme toute forme de vie, nous faisons partie du cycle hydrologique, mais maintenant des impacts négatifs majeurs sont présents à différentes échelles de l’environnement de l’eau et de notre planète bleue. Séparer les cycles de l’eau de l’action humaine serait plus prudent pour notre patrimoine hydrologique? C’est une idée polémique, mais étant donné que nous avons réussi à changer la composition chimique de l’eau sur la surface de la terre, ce n’est pas si radicale. En utilisant la gravité, il serait possible de faire passer l’eau à travers jardins et zones humides suspendus, filtrant et stockant l’eau et créant des habitats pour l’avifaune.

Échelle sociale, écologie et dynamiques

À mon avis, les échelles positives pour l’établissement et la saine pérrénité de l’espèce humaine sont celles de l’individu et de la communauté. Les villes d’une certaine manière ont changé l’échelle de nos communautés à l’échelle du paysage, à l’échelle régionale et à l’échelle macro. Si nous regardons notre quartier et les tissus sociaux de celui-ci à travers des méthodologies d’écologie du paysage nous pourrions y trouver des fragmentations, des effets de bord et bien d’autres phénomènes écologiques. La pensée écologique, au sens scientifique de l’écologie du paysage, peut-être la nouvelle approche holistique dans toutes les disciplines, et non seulement en biologie et sciences de la terre.

Quand vous vivez à Rio de Janeiro, se déplacer d’un endroit à un autre est un sujet de soucis, la ville a augmenté, mais les rues ne se sont pas élargies. La dernière idée géniale du gouvernement brésilien fût de promouvoir le transport motorisé individuel: la voiture. Comme le transport est à la fois une relation et un flux, le projet crée des voies suspendues et des tyroliennes entre les collines pour relier les bâtiments, les espaces publics, équipements, écoles, favelas et zones naturelles. Permettant de créer un environnement plus riche et efficient non seulement pour la nature, mais aussi pour les humains.

Utopie et considérations sur la réalité

J’espère que cette proposition générera des débats et suscitera l’envie d’autres utopies. Bien sûr de nombreux points n’ont pas été profondément développés et il ya quelques considérations sur l’intégrité des écosystèmes, mais cette proposition se veut provocante et novatrice autour de l’idée de la création de nouvelles communautés autour de nouvelles relations.

Tout le monde peut être préoccupé que des plantes nous tombe sur la tête, mais comme nous avons déjà jeté beaucoup de béton sur les marais, rivières et forêts, ce ne serait que le début de la facture dans la dure logique de la loi du talion, un oeil pour un oeil. Par mesure de sécurité, ne tentez pas de faire à la maison sans l’aide d’un spécialiste motivé, mais s’il vous plaît rêvez de nouvelles formes de nature pour nos villes.

Protecting More with Less: More Nature in Cities with the Science of Strategic Conservation

Many voices. Greener cities. Better cities.

By combining the benefits of structured decision-making with optimization, harnessing the power of markets, and the nuances of human behavior, we can achieve more nature in cities.

Not long ago, cities and nature were usually seen as two separate things. Thankfully nature and cities are now being acknowledged as inextricably linked, and an exciting and expanding movement is emerging to invest in green infrastructure that helps make cities sustainable, resilient, and livable.

Billions are spent annually around the world to support nature in cities. One investment strategy is to protect nature next to cities—creating defined edges or transition zones between developed areas and their surrounding natural areas and working landscapes. Another investment strategy is to integrate nature into cities—purposefully protecting and restoring green infrastructure inside urban areas, including the reuse of vacant and underutilized lands.

Despite the countless opportunities to implement each approach, very little attention has been paid to how cost-effective these investments are and whether governments and communities are getting the most “bang for their buck”. For over 10 years, Dr. Kent Messer (Unidel Howard Cosgrove Chair for the Environment at the University of Delaware and Codirector of the USDA-funded national Center for Behavioral and Experimental Agri-Environmental Research) and I have been on a journey to apply promising approaches that are commonly used in the business world, scientific inquiry, and policymaking areas outside conservation that help ensure more strategic and cost-effective outcomes. We are committed to bridging the “implementation gap” between academia and the conservation profession to use the best available tools from economics, operations research, behavioral science, decision analysis, and computer science to support cost-effective conservation and environmental stewardship of natural resources. We have successfully applied these tools in a variety of project contexts, leading to more strategic conservation, more acres protected, and shrewd use of available financial resources. Now we have completed our new book, The Science of Strategic Conservation: Protecting More with Less, as an effort to help publicize these efforts and scale the core principles of strategic conservation.

Significant advancements have been made in the theory and practice of conservation science to strategically identify the most important urban lands for biodiversity, ecosystem services, and other conservation objectives. Landscape ecology, conservation biology, and land use planning are some of the fundamental disciplines of strategic conservation planning that have been effectively applied to help achieve on-the-ground successes. We have attempted to harness these tools through the development of optimization decision support tools and applied projects that demonstrate how the comprehensive integration of these scientific disciplines into strategic conservation can help ensure the best conservation outcomes at a given level of financial investment—or, how specific conservation goals can be achieved at the lowest possible cost.

As a conservation planner, I am engaged in advancing structured decision-making tools able to quantify the benefits of potential conservation investments that result in better project selection and implementation. As a behavioral economist, Kent is engaged in cutting-edge research and outreach efforts related to efficient and effective environmental conservation. Our book highlights many of these advances in integrating these techniques into a variety of conservation contexts.

We provide examples in the book on how nature can be incorporated both “next to” and “into” cities. For instance, we showcase the development of regional forest conservation and restoration models for the Mid America Regional Council (MARC). MARC is the Metropolitan Planning Organization for the Kansas City region, so it oversees investments in transportation infrastructure. MARC was interested in forest conservation and restoration opportunities to avoid and minimize potential impacts to forested lands and to identify strategic mitigation opportunities when impacts were unavoidable. We built a GIS model that quantified the benefits of forest conservation and restoration within four categories: clean water (quality and quantity), clean air (carbon storage, pollution), quality of life (recreation, protected lands), and wildlife habitat (green infrastructure network). The resulting maps provided a spatially explicit framework for MARC and other partner organizations to optimize their investments in forest conservation and restoration projects.

We also showcase how the Upper Neuse Clean Water Initiative in North Carolina is using strategic conservation to creatively protect land parcels that support clean drinking water for the region’s municipalities. The Upper Neuse Clean Water Initiative is a collaboration by The Conservation Fund, Ellerbe Creek Watershed Association, Eno River Association, Tar River Land Conservancy, Triangle Greenways Council, Triangle Land Conservancy, local governments, and state agencies and is coordinated by the Conservation Trust for North Carolina. Together with willing landowners, these partners protect natural areas that are critical to the long-term health of drinking water from the Upper Neuse River basin by either purchasing parcels or establishing conservation easements on them. In its first 10 years, the initiative acquired ownership or an easement for 88 properties, protecting 84 miles of stream bank across 7,658 acres. In 2015, the initiative set a goal of protecting 30,000 acres over the next 30 years. We built a GIS model that examined every potential parcel in the watershed using multiple criteria and ultimately identified more than 17,000 parcels totaling more than 260,000 acres that would support the protection goal.

To protect more nature in cities using the science of strategic conservation and cost-effective conservation approaches, it is important to take a multiple benefits approach. For example, urban tree planting programs provide an array of human and natural benefits, including their value in ensuring clean air and clean water as well as providing habitat for wildlife. These ecosystem service benefits can be quantified using a variety of techniques and structured decision-making methodologies. The book illustrates numerous examples of quantifying the value of green infrastructure, including using decentralized stormwater management tools that can capture and absorb rain where it falls, thereby reducing stormwater runoff and improving the health of surrounding waterways.

More nature in cities can be accomplished on the ground by combining the benefits of structured decision making with optimization and the harnessing of the power of markets and the nuances of human behavior. By effectively developing, organizing, and prioritizing decision-making criteria in a structured and consistent way, cost-effective conservation tools can then be applied to get the most “bang for your buck” in an array of nature-based investments.

9. cruz-forman1. A just city repositions inequality

The conversation about justice and the city must begin with directly confronting social and economic inequality and prioritizing them as the main issue around which institutions must be reorganized. Contemporary architectural and urban practices must engage this political project head-on. We must question the neoliberal hegemony that has been imposed on the city in recent decades, which has exerted a violent blow to our collective economic, social and natural resources, producing an anti-public agenda whose ultimate consequence is an ever-widening gap between rich and poor. 

If we are interested in the Just City, we must begin by confronting the political machinery that endorses uneven urban development.
Today’s urban crisis is exponentially complex, as the consolidation of exclusionary power is both economic and political in nature, driven by one of the largest corporate lobbying machines in history. In the name of freedom, this machine has deregulated and privatized the public assets of our cities, subordinating collective responsibility to serve individual interest. Though the term “crisis” has become ubiquitous, we have become institutionally paralyzed in the context of these unprecedented shifts, silently witnessing the consolidation of the most blatant politics of exclusion, the shrinkage of social and public institutions and their role in the construction of the city. In that way, our crisis can’t be written off as a purely economic or environmental emergency. Rather, it is one of culture—a crisis of institutions unable to rethink unjust and unsustainable urban growth. 

If we are interested in the Just City, we must begin by confronting the political machinery that endorses uneven urban development. In other words, we must possess critical knowledge of the conditions that produced our urban crisis.  Without altering the exclusionary policies that have decimated our public culture today, urban design and planning will remain decorative enterprises camouflaging the greedy politics and economics of urban development that have eroded the primacy of public infrastructure worldwide.

In this context, the most relevant new urban practices and projects promoting social and economic inclusion are emerging not from sites of economic power but from sites of scarcity and zones of conflict, where citizens themselves, pressed by socioeconomic injustice, are pushed to imagine alternative possibilities. It is from the sense of urgency that a new political agenda is emerging, one in which urban design and architecture will take a more critical stance against the discriminatory policies and economics that produced inequality and marginalization. At this moment, it is not buildings but the fundamental reorganization of social and economic relations that is the essential for the expansion of democracy and justice in the city. 

2. A just city reengages the public

Since the early 1980s, with the ascendance of neoliberal economic policies based on the deregulation and privatization of public resources, an unchecked culture of individual and corporate greed has resulted in dramatic income inequality and social disparity. This new period of institutional unaccountability and illegality has been framed politically by the erroneous idea that liberty is the “right to be left alone,” a private dream devoid of social responsibility. But the mythology in which free-market “trickle down economics,” assures that we all benefit when we forgive the wealthy their taxes, has been proven wrong by political economists Saez and Piketty. They have exposed that both great economic upheavals in 20th century America—the crashes of 1929 and 2008— were also periods of the largest socioeconomic inequality and the lowest marginal taxation of the wealthy. The deepening of inequality in America is a direct result of the polarization of public and private resources, and this has had dramatic implications for the erosion of public institutions, and the uneven growth of the contemporary city, with its dramatic increase of territories of poverty.

However, these trends are not inevitable. Broad, structural political and social changes are still possible. Such changes have occurred at certain moments in history, when the instruments of urban development were primarily driven by an investment in the public. For example, there was the New Deal in the U.S. after the 1929 crisis, when a multi-sector institutional momentum took place that re-engaged public priorities by investing in public infrastructure, housing and education to re-energize the economy. Or the post-war Social Democratic urban politics in Europe, that framed the urban and economic growth of the European city by investing in public goods, such as Mitterrand’s Grand Project for Paris. How do we reinvigorate public investment? And how do we ignite new forms of civic participation, to demand these investments? 

A “just city” needs progressive public governance, driven by an ethical assertion that the good of the individual depends on the health of the collective, and an imperative to recalibrate the relations between individuals, collectives and institutions. At a time when the extreme right and the extreme left on the political spectrum share a distrust of government, we urgently need to reclaim the role of government to prioritize public interests, and enact the protection systems—social and economic—that can stem the trend toward radical inequality. We need a new political leadership that engages the marginalized sectors of our societies, committed to efficient, transparent, inclusive and collaborative forms of local governance.

3. A just city redistributes knowledge

Social Justice today is not only about the redistribution of resources; it should also promote the redistribution of knowledges. The polarization of public and private interests in the city has produced a rupture between institutions and publics. At the University of California San Diego, where we lead the Cross-Border Initiative, we have been pursuing new strategies of “knowledge exchange” between the top-down and the bottom-up. In one direction, we examine how specific, bottom-up urban activism can trickle upward to transform top-down institutional policy and practice; and, in the other direction, we investigate how top-down resources can reach sites of marginalization and support bottom up intelligence. This journey from the bottom-up to the top-down is urgent today to rethink urban justice, and it requires new forms of institutional representation and urban education that can translate and facilitate the everyday practices and needs of marginalized communities into new development logics for inclusive urbanization. 

Our campus is barely thirty minutes away from the most trafficked border in the world, occupying one of the most contested and uneven trans-national global regions, where urbanizations of wealth and poverty collide and overlap daily. In the context of such social and economic disparity, many underserved neighborhoods in our region have constructed alternative models of urban sustainability, resilience and adaptation to redefine urban growth. We claim that learning from these bottom-up forms of local socio-economic production is essential to rethinking urban density through new strategies of urban coexistence and interdependence. 

We created the Cross-Border Community Stations Project as a platform for these exchanges, linking the specialized knowledge of the university with the community-based knowledge embedded in marginal neighborhoods on both sides of the border. This two-way flow, as universities engage communities but also communities enter into the universities, suggests the need for new forms of teaching and learning that can expand pedagogical processes beyond the classroom and embed them in the everyday social life of communities. 

This encounter between formal and informal knowledge requires new conceptions of public space, as a space of education and knowledge production. This involves the transformation of empty spaces into active civic classrooms, spaces of knowledge, research production and local economy. The University of California, San Diego refers to these field-based laboratories as “Community Stations,” new public spaces where research, teaching and community activism are co-curated collaboratively and where a new environmental literacy and cultural action can stimulate political agency at the scale of communities. 

In particular, this collaborative urban pedagogical model between research universities and local community-based agencies emphasizes that marginalized communities and major universities can be meaningful partners with knowledge and resources to contribute, in the search for solutions to deep social and economic challenges, to improve the quality of life across these underserved, demographically diverse neighborhoods.  

4. A just city rethinks beautification

A Just City will move the idea of beautification from aesthetics for aesthetics’ sake into an expanded, more complex idea of beauty. As cities become increasingly defined by architecture that only serves to camouflage and deepen exclusionary politics and economics, it is urgent that we challenge the steady march of decorative revitalization. 

Beautification has long been an excuse for the displacement of communities. Yet today, the issue seems more relevant than ever, given the way it has been leveraged for exclusionary ends by seemingly progressive urban agendas such as New Urbanism and the Creative Class movements. It is not enough for New Urbanism, with its obsession with form-based code and stylistic historicism, to retrofit suburbia with a “prettier” themed façade, if the ownership models that define such infill developments remain mono-cultural, aesthetically homogeneous and unaffordable. These neoconservative urban trends have been adopted by many municipalities across the U.S., and have done nothing to rethink existing models of property by redefining affordability and the value of social participation, enhancing the role of communities in coproducing housing, or enabling a more inclusive idea of ownership.

Equally, the Creative Class agenda has only capitalized on the aesthetics of cosmopolitan hipster enclaves that are supposedly driven by artists and cultural producers, without providing truly affordable rents for artists and accessible infrastructures for fabrication and cultural production that are necessary to incentivize local economic growth in and for neighborhoods. With their facades of beautification and innovation, both agendas pave the way to gentrification and fail to advance social or economic justice in the city.

The Just City requires a more experiential dimension of beauty, less based on a visual quality and more on a sort of subliminal drama and vibrancy, a process of encountering and co-existing with the “other;” an aesthetic quality that embraces contradictions. It is about the construction of a sense of aesthetics that requires risk. In other words, it is an idea of beauty that does not smother and suppress contradictions or conceal conflict, but emerges out of  socio-economic and political inclusion. A city is beautiful to the extent that it is inclusive, and one whose public spaces are not merely catalysts for architectures of privatization, but are generative of urbanizations of social justice.

5. A just city reimagines citizenship

Antanas Mockus, former Mayor of Bogota, Colombia, insisted that before transforming the city physically, we need to transform social norms. To Mockus, urban transformation is as much about changing patterns of public trust and social cooperation from the bottom-up as it is about changing urban, public health and environmental policy from the top-down. Mockus enacted a distinctive kind of egalitarian political leadership, declaring emphatically the moral norms that should regulate our relations: that human life is sacred, that radical inequality is unjust, that adequate education and health are human rights and that gender violence is intolerable. He reorganized public policy by nurturing a new citizenship culture, grounded in a moral claim that human beings—regardless of formal legal citizenship, regardless of race—have dignity, and deserve equal respect and basic quality of life. 

In rethinking urban justice, Mockus developed a corresponding urban pedagogy of distinctive performative interventions to demonstrate precisely what he meant, inspiring generations of civic actors, urbanists and artists across Latin America and the world to think more creatively about engaging social behavior. Meeting urban violence with stricter penalties will not work. Law and order solutions don’t interiorize new values among the public.

For example, he believed in modeling desired behavior by, for example, showering on public television to demonstrate how one turns off the water when soaping up. One famous example of urban pedagogy is that early in his administration, Mockus replaced the corrupt downtown traffic police force with a troupe of 500 street mimes who stood on street corners and shamed traffic violators by blowing whistles, and pointing, and holding up signs of disapproval: “incorrecto!” To many it looked like a circus, and Mockus drew criticism; but in this act of public shaming, the mimes were instituting a new social norm of compliance with traffic signs; and it worked. Their antics became a citywide sensation; every one was watching on television, and traffic fatalities declined by 50% in Mockus’ first administration. Additionally, Mockus distributed placards across the city, one with a thumbs up sign, the other with a thumbs down; and he encouraged citizens to use these placards to communicate approval and disapproval to one another. The changes were palpable: people began to look at each other and recognize each other. In a very short period of time, a new sense of civic responsibility began to emerge in a city that had fallen into complete dysfunction and violence. At the same time, a new trust in government began to take hold as Mockus won the hearts of citizens, and he accompanied this bottom-up normative change with massive top-down municipal investment in social service and public works, improving peoples lives in very tangible ways.  Naysayers could not deny the proof: During Mockus’ first administration, murders were reduced by 70 percent, traffic fatalities by 50 percent, tax collection nearly doubled, and water usage decreased by 40 percent while water and sewer services were extended to nearly all households.

What Mockus’ work demonstrates is that urban social norms can be reoriented through top-down municipal intervention through community processes. These are fundamental lessons that can be brought to the American city, primarily today when neighborhood violence has been exacerbated by the resurgence of racism and police brutality, but also by current anti-immigration ideology, which together with the exclusionary policies it engenders has deepened injustice in the city. 

From the vantage point of the border territory where we live and work, social norms here have incrementally hardened against immigrants and immigration, alongside the hardening of the legal, social, economic and physical walls between the United States and Mexico. Our borders have been militarized in tandem with legislation that erodes social institutions, barricades public space and divides communities. Such protectionist strategies, fueled by paranoia and greed, are defining a radically protectionist social agenda of exclusion that threatens to dominate public life for years to come. 

A community is always in dialogue with its immediate social and ecological environment: this is what defines its political nature. But when the productive capacity of a community is splintered by political borders, it must find ways to recuperate its social agency and entrepreneurial potential. This is why we have always been inspired by the poor, immigrant neighborhoods on both sides of the San Diego-Tijuana border, whose residents are redefining urban sustainability and pointing to new ways of constructing citizenship. A just city depends on a political leadership that recognizes our interdependence and reaches across borders to produce new strategies of coexistence. And it is precisely within the marginalized yet resilient immigrant communities flanking the border that such a conception of civic culture will emerge, one whose DNA is composed of empathy, collaboration and shared values. 

Isolationism is no longer an option in today’s world of global interconnectedness.  Ethically, we cannot ignore the negative impact that our decisions, choices and habits have on others near and far; nor can we impose our will on others by force. The problems of Mexico and Central America are ours. The fallout of climate change on the global poor, most of which the rich countries of the North have caused, is our responsibility. The dramatic injustices perpetrated against marginalized populations in Ferguson, MO and undoubtedly countless other cities across the U.S. cannot remain invisible, isolated from the halls of Washington. We cannot wish the problems of such places away with market solutions, or with guns and fences; instead we must listen to and cooperate with those most affected by our policies, globally and domestically.

At bottom, we need to recover a sense of collective commitment to the least well-off among us. Social justice must reassert itself at the center of today’s public discourse, and we must also recover a sense of cultural empathy, the sort emblazoned on the Statue of Liberty’s plaque:

A mighty woman with a torch, whose flame
Is the imprisoned lightning, and her name
Mother of Exiles. From her beacon-hand
Glows world-wide welcome; her mild eyes command
The air-bridged harbor that twin cities frame.
“Keep, ancient lands, your storied pomp!” cries she
With silent lips. “Give me your tired, your poor,
Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore.
Send these, the homeless, tempest-tossed to me,
I lift my lamp beside the golden door!

In a just city, economic and urban growth cannot come at the expense of social equality and inclusion. The drive to privatize must be tempered by an interventionist, disruptive commitment to public investment in infrastructure and general social welfare. The market will not solve our problems. Public and private interests must be harmonized. The public, particularly the poorest members of it, must take their cities back. Government must become transparent, efficient, and inclusive, with massive investment in new strategies of civic engagement to reignite a new public culture capable of making claims on its own behalf. Today, mistrust of government and hollow notions of progress and freedom for all have undermined the possibility of drawing upon the shared democratic values that unite us. Citizenship has become a polarizing concept, caught up in narratives about protecting “our” resources from “them.” In the just city, a more inclusive citizenship culture, based on shared values, commitments and common interests, rather than rigid jurisdictional categories that dehumanize the other, must be the foundation of a new public imagination.

Putting Nature Back Into the Natural Beauty of Rio de Janeiro

Many voices. Greener cities. Better cities.

It is an irony that despite the magnificent natural beauty of Rio de Janeiro, the city itself is largely devoid of functioning nature. It is now time for Rio to not only to host global events such as the World Cup and Olympics, but to host its primary nature, not outside the city, but in the middle of its streets, plazas and buildings. This blog discusses a case study – the greening of the Carioca River watershed that emerges from Tijuca National Park – as an example of what we could accomplish for the good of all Cariocas (which is what residents of Rio are called).

The presence of nature is decreasing in the daily life of Rio due to the expansion of the impervious area at many scales, from street to district scale, architectural models of arid constructions and street tree plantings that are getting old. Slowly the nature is being “expelled”, transforming the city in an hot and arid landscape.

Hot days are more frequent, transforming the city in an uncomfortable and stressing way. Credit: P. Martin.

The city of Rio de Janeiro has a semi-humid tropical climate, with hot and humid summers and mild and dry winters. Climate change forecasts in the medium to long-term for this region indicate more peaks of heat and rain, more drought, a rise in average temperature and larger drought periods (Megacidades, Vulnerabilidades e Mudanças Climáticas: Região Metropolitana do Rio de Janeiro). The future may be one of environmental imbalance, mainly because of alteration of quality and quantity of water and strong changes of the vegetation land cover, plus other alterations to natural systems and their co-relations.

What can Rio, its government, and its citizens do to face these new challenges? Urban design issues focused on nature efficiency can be a response. Here are some conceptual experiments and designs on the potential presence of nature into the city.

Case study: the Carioca River watershed

Rio de Janeiro will host the World Cup and the Olympic Games in the coming years but it will also host global changes like rising temperature and more extremes of humidity. We know that ecosystems can be effective regulators of the environment, especially at local scales (Millennium Ecosystem Assessment), so we will propose nature, in this speculative exercise, as a method of regulating heat and humidity for our urban environmental scenario in the medium term.

To illustrate Rio’s current conditions and create contemporary design proposals to reverse the lack of nature and its immediate consequences, we will study the Rio Carioca watershed for its iconic abiotic, biotic and social status. It is unfortunately not valued by the city or many of its residents, but it will at least illustrate problems the city is facing in its everyday life but not in its political decisions. (See also here.)

The watershed of Rio Carioca has been occupied by humans since the dawn of colonial occupation because of its fresh water, firstly by local farms, later by industries, and then finally by planned residential neighborhoods. The Carioca River was a source of fresh water for most of the settler population. In 1750 the river was diverted to supply the downtown Rio’s fountains and the arches of Lapa aqueduct, which conducted the water, remains today. The aqueduct is now a historical monument is used as a bridge and is the most iconic element of this neighborhood. However, only a very few remember what was its original purpose.

A city between hills and lowlands

The geology of the city mainly separates the territory in two main classes that are hills of granite or gneiss and lowlands constituted by silt, sands or landfills. During the 20th century many hills were used for landfill and wetlands filled to create more territory near the ocean and the bay. This territory has been highly transformed by built infrastructure, and even its national park, Parque Nacional da Tijuca, was reclaimed, at the end of the 19th century, after coffee plantations drained most of the rivers of the city. Major Archer was responsible for planting 100,000 trees and restored this forest with native plants.

Most of the watersheds pass through these geologies and the natural lowlands were occupied by marshes, lagoons and meandering rivers. Nowadays the city is concentrated in the lowlands and and the natural history has largely been removed from the urban landscape. The Carioca River watershed, even if it is not the worst environmental example in the city, has a clear and strong gradient: green in the hills, but very grey in the city.

Blue system, lost river

Today the Carioca River has disappeared from the city. It is covered by infrastructure soon after it enters the formal city and only reappears near Guanabara Bay in the middle of Flamengo Park, a masterpiece of landscape architecture by Burle Marx. Ironically, the river passes through a sewer treatment plant as it arrives in the park, revealing the true official recognition by the authorities that the Carioca River is no longer a river but a sewer system.

We cannot hide our problems under the rug (or concrete) and it is time to rethink the role of water resources in the city and recognize that the health of our environment must be measured against the health of our urban waters.

Green systems, fragmentation and anthropization

Rio de Janeiro recently won the title of UNESCO world heritage site and reasons for winning this award abound in this watershed. For example, Tijuca National Park, an approximately 4000 hectare conservation unit (CU) created in 1961, successfully protects Atlantic Rainforest biodiversity in the middle of the city, although it has always suffered influences from the actions of Man (As marcas do homem na floresta – História ambiental de um trecho urbano de mata atlântica). Nowadays the sum of all CUs in the municipality of Rio de Janeiro represents one third of its territory. However, most of these conservation parks are at the edges of the city with few entrances and distant from the central cores. On the one hand they provide excellent stages for conservation, but their remoteness means that most residents have little contact with nature except for distant views. Natural landscapes in Rio are more background than foreground.

Full city or empty nature?

To examine the watershed more closely we divided it into seven parts of equal length as a tool for interpretation and analysis – like botanists do in surveys of biodiversity – drawing grids and surveying parcels on the land. Summarizing, we can read on the landscape the following four main typologies.

  • The top of the hills with scenic views acting as natural belvederes and monuments, such as the Cristo Redentor statue – highly touristic sites but only suitable for short visits.
  • The border between the forest and the city, where there are expensive residences occupying big parcels and slums situated in between infrastructure and residual spaces.
  • Middle-class residential vertical neighborhoods and their infrastructure.
  • A large modernist park on landfill areas.

Reading this territory it is clear that the gradient of green to grey is also a gradient of population density in a city that has been emptied of nature. When I say nature I mean efficient ecosystems, not man made gardens with mainly esthetic purposes. So actually we have quite an empty city with a full nature only around the city at its edge.

The forest

Tijuca National Park does a really great job at interpretation for visitors, with all of its trails mapped and signage in place. It interacts actively through neighborhood meetings with all communities touching its border, but the two million+ visitors each year are mainly tourists who enter into a funicular in the middle of the city, jump out of it when arriving at the Corcovado statue (Cristo Redentor) and return after taking a few pictures of the city and its unique territory from above.

It is a missed opportunity that so many people from all over the world pass through the forest but do not have real contact with it or an understanding of its particular ecology. This is the point that should be better developed in one of the biggest urban forests of the world: connecting the forest and the touristic points with accessible and educational trails expanding the tourists’ knowledge of one of the best fragments of Atlantic Rainforest and its ecosystem services, such as biodiversity habitats, atmospheric and temperature regulation and water purification.

The border between the forest and city

This area is complex, with a mix of environmental, urban and historical restrictions and sometimes many public owners, such as the city, the state and the federal government. There is interpenetration of private and public spaces and some “nobody” places that are, for example, the buffer zones around energy and transportation infrastructure and  properties of undetermined ownership. This area needs to be activated ecologically, and given sustainable uses. For example, small scale slums have social and economic demand for natural land uses such as agroforestry. This border could be co-managed in a model of land use similar to the Satoyamas in Japan.

These borders experience significant pressure from ecological edge effects and invasive of species such as the jackfruit tree, Artocarpus heterophyllus Lam., which compete on the Forest floor with native species. An active and planned use with co-management of population and public entities will result in more security for the population and the ecosystems.

The city

In Rio our public spaces such as street and plazas suffer from deficient maintenance and no systemetic planning for urban trees and permeable surfaces (i.e., areas without concrete where water can be absorbed). The main activity of public agents in public spaces is just cleaning or tree pruning. There is still a culture of concrete as a symbol of modernity, which results in an urban environment that acts more like a bathtub than as a natural system normal water flow and biodiversity.

Our proposals look to increase vertical biodiversity as a response for the vertical city that occupies most of the watershed with urban territory that lacks trees, soil, and permeable surfaces. Our idea is to use the huge range of epiphytes of the Atlantic rainforest that can be used for vertical gardening that does not require irrigation or strong support structures. Complementing this action would be extensive natural green roofs that could restore native herbaceous ecosystems of this biome and also serve as habitat for birds.

The big park

This is for sure a polemical issue because Flamengo Park is a masterpiece of designer Roberto Burle Marx, and a landmark for the city, its citizens and their common history. We will not enter here into a discussion about the park’s esthetic or historical value. The issue here is mainly about ecology and environmental efficiency of this 1.2 million square meters of public space.

Actually the park is almost a giant lawn with a really diverse trees but virtually no shrubs or wet zones. You can see gardeners cutting its lawn all year long making a lot of air and noise pollution…not so efficient for maintenance.

The way the herbaceous layer is designed should be rethought so as to complement it with shrubs, native grasses with only one or two cuts a year. The first ecological renovation could be implemented as a test for social understanding: the Carioca River, after it is no longer used as a sewer line.

Conclusion

This proposal is clearly a meant as a provocative and reactive initiative but it is surely aligned to the importance of the Brazilian biodiversity and its main biodiverse biome: the Atlantic Rainforest. It is now in time for Rio de Janeiro not only to host global events but to host its main nature, not outside the city, but in the middle of its streets, plazas and buildings.

Putting Nature First: Driving Actions for Nature in Cities

Many voices. Greener cities. Better cities.
Cities need to put nature objectives in strategic agendas and then commit to achieving them through meaningful investment and means for accountability. Simply put: get nature on the agenda and act for it.
The COVID-19 pandemic revealed how important urban nature is for our physical and mental health. As urban strategists embark on ideas and think of pathways for recovery and “building back better” our societies and especially cities, it is paramount that the green recovery include nature in the mix of options that cities consider. Nature (varying from remnant ecosystems, novel ecosystems and various nature-based solutions) needs to be one of the highest priorities on the agenda for building resilient and thriving cities. With this thesis in mind, we bring three core messages to the global community of practice for urban nature: (1) cities play.a critical role in biodiversity conservation; (2) cities must put nature at the forefront of planning and action; and (3) cities must promote and enable inclusive governance for urban nature.

First, cities have a role to play in dealing with the extinction crisis and with protecting biodiversity and that means they need to act upon it (Oke et al., 2021). The first step is to recognize the potential of cities as places for biodiversity and as spaces where nature can be restored and protected (Ives et al 2016; Garrard et al 2018). Global reports for biodiversity and climate adaptation (e.g. United Nations Environment Program, 2021) document and provide evidence for the effectiveness of actions as well as for the opportunities that cities offer. Yet, simply being sites of opportunity, however, does not guarantee that the opportunities are seized nor materialized. Cities, and their multilevel governance partners, need to realize and act upon the opportunities they have in contributing to urban biodiversity finding solutions to the extinction crisis through connecting global perspectives with a local focus.

While cities may feel constrained by contested interests and a nexus of necessary institutional arrangements that need to be in place; however, many cities are showcasing that when there is a will there is a way. Across the globe, cities grappling with opportunities for making transformational changes with nature have paved the way for others to follow. In the mix of daring cities, we find Melbourne with a global first metropolitan-wide strategy for Urban Forests, connecting and coordinating multiple actions across 32 municipalities and setting an enabling (policy) context for more actions to emerge along the way (Fastrenrath et al 2020; The Nature Conservancy and Resilient Melbourne 2019).

In fact, many cities in Australia are motivated to take action by regenerating urban parks, making biodiversity plans at city level and responding to state-level targets on canopy cover with broader than simply ‘trees in parks’ strategies incorporating biodiversity and renaturing initiatives. The recent announcement by the city of Paris for making an urban green park in its iconic Champs-Élysées boulevard as a next step to its rolling out rooftop cover strategy also falls into this category. It is about realizing the important role that cities can play in dealing with biodiversity crisis and taking daring action to realize in full potential the role, and for this to be recognized by governance peers.

Second, cities need to put nature objectives in strategic agendas and then commit to achieving them through meaningful investment and means for accountability (Oke et al 2021). Simply, put nature on the agenda and act for it. Cities’ agendas drive action and are the institutional ‘signposts’ for committing political will or showing political commitment. Until now, guidance and research for designing and implementing city agendas for nature, is rather heavy on critique and light on constructive guidance, yet we recognize that science and research can play a critical role in co-shaping and informing city agendas.

For cities to put nature first in strategic urban agendas they need to:

  1. Employ a system’s approach to guide biodiversity agendas. Approach the full planning cycle with a system’s perspective, from objectives setting to developing implementation programs. This means looking at interactions, feedback loops, and co-benefits between solutions and interventions as well as between biodiversity and other strategic priorities. In this way, more opportunities and also institutional spaces for innovation can be enabled.
  2. Mainstream resilience principles in planning with and for nature-based solutions. With much knowledge and evidence from practice of how to achieve urban resilience through global city initiatives and city networks (e.g. 100 Resilient Cities now evolved into Global Resilience Network, as well as other city networks such as ICLEI-led Cities with Nature), a more daring step will be to adopt resilience principles as guiding or foundational principles for urban planning. Instead of spending resources and time to advocate for the need of an urban resilience approach, cities now have to leapfrog into mainstreaming them to support further the planning and implementation of nature-based solutions as critical for biodiversity and climate adaptation in cities (Race to Resilience: https://racetozero.unfccc.int/race-to-resilience/).
  3. Mainstream experimentation to enrich and strengthen in-house expertise in cities. Urban planners and urban strategists have deep knowledge and expertise on their thematic spheres. This is a resource to be tapped into when putting nature on the agenda as well as for designing plans and programs for it. The in-house expertise should to be woven with recent academic knowledge in ‘safe spaces’ through experimentation and co-creation. In addition, urban governments may benefit from building in-house ecological and scientific expertise where this is lacking. Experimentation requires commitment to monitoring and evaluating the outcomes of actions, and to identifying opportunities to turn ‘failure’ into new approaches and improved responses. We thus propose that many cities can mainstream experimentation as a way to extend and update and put learning into the ‘making of’ the city with nature (Frantzeskaki et al 2019, 2020).

Third, cities need to engage with diverse actors so as to plan and govern nature in cities inclusively (Oke et al 2021). Cities are connected landscapes: landscapes of nature and cultures. As such, every intervention or transformation in the fabric of urban landscapes needs to weave in and engage inclusively with multiple actors. For finding ‘whose nature it is’, there are different lenses and approaches to take on board, each one with benefits and blind spots. A common aspect in all cities is that globalization as an unstoppable driver creates multicultural cities and urban spaces that are always in flux.

For cities to govern nature (and nature-based solutions) inclusively they need to:

  1. Renature co-creatively with Indigenous communities. Bringing and/or sustaining nature in cities is an action for ecological, economic and social sustainability and responds to the quest for intergenerational justice. But thinking and caring for future generations comes hand in hand with respecting, understanding and caring for our history and predecessors. Here is where Indigenous communities and their care for nature, care for place and planet and specifically in Australia “Caring for Country” is of vital importance to lead urban renaturing.
  2. Give voice to cultural meanings of nature in cities. Alongside strategic narratives and business cases for nature in cities, cities should include cultural meanings of nature in the form of narratives, imaginaries, songlines, or images. Place-based understandings and narratives can provide a new form of understanding of how to better integrate or re-introduce nature in cities especially in places that are contested, under conflict or socially or ecologically vulnerable. Cities can foster and enable this weaving of cultural meanings through, for example, transforming existing (and often long-standing) city festivals to embrace multi-cultural meanings, to make the “invisible visible” and to represent diversity.
  3. Embrace citizen science to make inclusive urban nature programs. Citizen science offers an additional lens and means through which to shed light to people’s use of, preferences for and meanings of urban nature. It can complement traditional social science or marketing methods to unravel citizens’ needs and activate feelings of belonging and empowerment that are important both for embracing nature in cities and being active urban citizens.

Cities are critical places for tackling the global challenges of climate change, extinction crisis and pandemics. But to do so, we need to foreground biodiversity in actions for nature in cities. This implies a shift in the way urban priorities are set, a move from considering biodiversity and nature in cities as a luxurious after-thought or beneficial add-on to acknowledging them as a key starting point for planning and building inclusive, resilient cities of the future.

Quarantine Fatigue and the Power of Activating Public Lands as Social Infrastructure

Many voices. Greener cities. Better cities.

This essay is part three in a series. Since 13 March 2020, our team of social science researchers has been keeping a collective journal of our experiences of our New York City neighborhoods and public spaces during COVID-19. Read the essays from spring and summer here.

Our public landscapes have the capacity to absorb so much of our personal trials and our societal tribulations. But it is active stewardship that can, at its best, transcend politics and build trust between people. When we have trust in each other, we have hope. 
1. Winter is coming: Second wave and quarantine fatigue

In New York City, after a bit of respite this summer, infection rates are rising again as we are facing a second wave. Among our research team, we have friends and family who have gotten ill, a reminder that the virus is very much still present as a threat. In our communities, we observe that there is persistent need and acute risk of hunger—with municipal agencies, religious organizations, and mutual aid groups continuing to serve as frontline providers of food relief and social services to meet the needs of the most vulnerable. After just eight weeks of in-person schooling, NYC public schools moved to an all-virtual format on 19 November. Yet, indoor restaurant dining, gyms, and nail salons still remain open in December, raising ire among some parents and prompting multiple opinion pieces on the matter (see also this). This rollercoaster of openings and closings continued as the city announced a plan for resuming in-person learning in public schools starting in mid-December. No more than days after this announcement, plans for reopening changed again. Fatigue sets in from constantly having to recalibrate things like daily work-school-shop schedules and many routine activities. Everything is fluid—testing our own adaptive capacities.

We have all had to adapt, cancel, or move to virtual our planned family fall gatherings and holidays. The CDC issued official guidance encouraging Americans not to travel for Thanksgiving celebrations, which was amplified in the social media space through norming and shaming like the trending meme “I’d rather have a zoom Thanksgiving than an ICU Christmas.” Further, we navigated a patchwork quilt of COVID-related restrictions that varied by state and county, including everything from travel-related quarantines, to curfews, to business shutdown, to bans on outdoor socializing outside the household. We feel the weight of our own personal decisions and responsibilities as we navigate household variation in risk perception, and socio-cultural norms–which are not uniformly shared.

Excerpt from Laura’s journal, 21 September:

I wanted to share a few reflections from Rosh Hashanah this past weekend. On Friday I baked challah and cooked a big meal for my zoom family dinner. Since COVID has made many of our usual holiday traditions unsafe it felt important to focus on the things I could still do, like make an apple cake that filled my apartment with a familiar smell and connect virtually with family members who are normally too far away to see this time of year. Saturday my partner and I drove to Connecticut for an outdoor picnic lunch with my family and the tashlich service (where we throw bread into water to symbolically cast away our sins). My brother-in-law led a short and socially-distanced service in the parking lot of his Synagogue; every other parking space was filled by one family unit and they asked us not to sing along for COVID reasons, a reminder that the new year was starting in a very different context. But then we did tashlich in a nearby pond and the simple act of throwing breadcrumbs into water felt unchanged. Back in Brooklyn on Sunday I went to an outdoor “shofar across Brooklyn” service at Grand Army Plaza and reflected on the power of participating in ritual in a public space.

As we move into our tenth month of the COVID-19 pandemic, quarantine fatigue is real. Recognizing that there are axes of incredible difference based on social vulnerability that shape personal exposure to risk, we are all–in unique ways—experiencing the sustained impacts of this public health crisis, the cascading economic effects, and the transformations of our social worlds.

Excerpt from Lindsay’s journal, 30 October:

On the personal front, I think I’ve finally realized that I am entering a stage of fatigue. I’m working a ton, I’m home with Mia, Ricardo does almost all the cooking, but still I find myself with zero time—no exercise, not seeing friends. Time is just flying by. I miss the sum total of lived experience in the city. No, I don’t miss commuting, but as my friend Minna said, “I miss the randomness.” It’s all just starting to wear down—the sameness, being home all the time, connected only through the computer. I miss my SOCIAL WORLD. I keep thinking about Erika’s comments from Frank Snowden. So hard to put a finger on, to capture, and to see, but that erosion of our social bonds is real, personal, and deeply felt.

Yet, we have seen an amazing range of adaptations that allow us to sustain and continue our social and economic lives. Here in New York City, we have moved more of our lives outdoors—particularly in our parks and open spaces, which have become even more the lifeblood of the city, hosting outdoor fitness classes, classrooms, book clubs, birthday parties, playgroups, community dialogues and more. Municipally-enabled programs of Open Restaurants, Open Streets, and Open Storefronts transform and repurpose the public right-of-way for diverse uses. Yet, these programs cannot fully support or save whole sectors—arts and culture, retail—the economic impact is staggering. As of September, fewer than 10% of Manhattan office workers had returned, with cascading impacts on retail, restaurant, and service providers connected to those workers. For colleagues that work in these sectors, we have little to offer but sympathy and worry, mumbled apologies and distress.

Overall, many have expressed the feeling that the novelty of distanced socializing and outdoor dining is waning.  With shorter and colder days, comes a grim sense of preparing for a long winter. We are now all acting like amateur meteorologists (as well as amateur epidemiologists), keenly aware of sunrise, sunset, temperature gradients, and wind chill factors. Many people are getting serious about thermals, boots, jackets, and space heaters. But all the best gear and “can do” attitude doesn’t fully shake the feeling of dread and worry about what lies ahead over the next few months. Yet, with recent announcements on the development of vaccines, we can see a light at the end of the tunnel. With spring, summer, and vaccines ahead, we redouble our efforts to stay safe and sustain ourselves and our communities through this winter.

We cannot write about this fall without reflecting on the impact of the election. As federal employees and researchers, it is not our role to take a political stance. But as observers of our social worlds and cultural milieus, we can plainly see that once again our public spaces serve as crucial sites for contestation, celebration, and protest. We are reminded that there are few places other than public lands that have the capacity to absorb all of our strife and angst, our protest and peace. And sometimes, all of it can be expressed in one weekend and within a single public space.

2. The power of public lands and the possibilities of social infrastructure

Given all of these overwhelming divisions and chronic challenges, how can our public realm continue to offer social support? When and how can our shared public spaces at minimum meet a wide range of needs and, at best, help us to come together or transcend these differences?

First and foremost, the power and potential of public lands lies in the fact that they are just that—public and open to all. We have been conducting a series of interviews with city, state, and federal land managers across the northeast, asking them to reflect on the role of the forests and parks that they steward in light of the events of 2020—including both COVID-19 and the uprisings around racial injustice. A consistent theme we heard echoed again and again at every scale of government is that these lands are for everyone:

  • A New York City Parks administrator said, “[our park] is a place for people to come together and is welcoming of all people” and “We have this incredible open space resource. It’s an educational resource and a recreational resource, but we have to find out how we can best be of use to those [under served] communities.”
  • A New York State Parks official said, “public lands are for all.”
  • A National Forest representative said, “make people see that this forest, this public land is YOURS.”

Since the start of the COVID-19 pandemic, there has been a renewed attention to the importance of green space and nearby nature as a crucial resource that supports all dimensions of physical, mental, social, and emotional health and well-being. Going further, the pandemic has shined a light on pre-existing inequities in the distribution of, access to, and financing and programming of these greenspaces across landscapes and communities. As has been well-known in environmental justice circles for decades, access to parkland and tree canopy is uneven, including along dimensions of race and class (see, e.g., Grove et al., 2018; Heynen, 2003, Schwarz et al., 2015; Watkins & Gerrish, 2018).

The NYC City Council Parks and Recreation Committee held a hearing on 22 October on this very issue: “Improving the Equity of Green Space throughout the City in Light of the COVID Epidemic.”  Not only did the NYC Parks Commissioner, Mitchell Silver, offer testimony, but dozens of non-profit partners, advocacy groups, labor unions, community gardeners, park workers, and committed residents and stewards spoke out on the need for an equitable open space system, now more than ever.  As Forest Service researchers, we too offered testimony, reflecting in particular on the importance of civic groups and their role in activating these public spaces as social infrastructure. While it is important to focus on the physical resource of parks and open space, it is not enough. We also need to support people and organizations that care for these green spaces, so that they can truly function as equitable and inclusive social infrastructures. Community organizations play a pivotal, but often unseen role in supporting public open spaces and activating them as social infrastructure — leveraging significant person power, time, and resources (Landau et al. 2019).

During times of disturbance, these civic stewardship groups act as “green responders”. After a crisis, first responders help to stabilize life and property. As part of longer-term recovery and preparedness cycles, stewards can help to rebuild communities and landscapes through environmental action (Campbell et al. 2019; Svendsen and Campbell 2010). The act of caring for local places can transform not only the physical environment, but also our relationships to those places and to each other. In the wake of COVID-19 and the murder of George Floyd—two crises that co-occurred and intersected, we saw many stewardship groups spring into action to address new needs that came from the pandemic and the uprisings around racial injustice:

  • One group added a set of “recovery icons” to their open source digital mapping materials, so that stewards and activists around the world can map assets such as food banks, temporary housing, and hand-washing stations.
  • Another group that was impacted by loss of funding for the city’s public composting program responded by partnering with other compost groups to advocate for a partial restoration of the community compost budget.
  • A group in the Rockaways more than doubled their farm share program and offered free Thanksgiving dinners to support community members in need. In addition to their food justice work, their educational team also created a documentary reflecting the lives and stories of their youth participants during the pandemic.
  • A group in Flushing pivoted to providing online content – including a virtual environmental justice book club – to keep participants connected in conversation and community and fight “quarantine monotony”.
  • During the protests in the wake of the George Floyd murder, banners riffing off the NYC Parks official COVID social distancing signs appeared in some parks in Brooklyn. While they are not park of the parks’ official signage, they have been left up and serve as a reminder that public lands serve as sites of expression.

Civic engagement is critical to public space. In addition to providing labor and increasing capacity, it strengthens democracy via empathy, innovation, and fostering social trust. For example, a study of volunteer tree planters participating in the MillionTreesNYC found that–other than voting or attending religious services–tree planting was many participants’ first act of volunteerism; follow up interviews found that they went on to be more highly civically engaged in their communities in other ways. As such, we find that environmental stewardship can be an on-ramp to other forms of engagement (Fisher et al. 2015). Civic stewardship can increase community and cultural relevance by providing locally tailored and specific programming, events, and activities. Prior to the pandemic, one local friends-of park group in Queens organized nighttime dance parties, public health fairs, and arts activities for children to bring diverse residents together around issues they cared about–all with a fun and educational tone. And this summer, a group in Brownsville, Brooklyn responded to the shifting needs of their community members by building out a focus around mental health care and wellness. In addition to new needs that have emerged during the pandemic, groups have also continued annual events, like raking leaves, which can feel like rituals, grounding neighbors in time and place.

Excerpt from Lindsay’s journal, 26 October

This past weekend, I did some long-overdue stewardship on Pioneer Street, after having been dormant for a few seasons. Marisa (friend, neighbor, and garden steward at Pioneer Works) and I organized it and ALL the kids in our building came out to help. We created a new stone border on the empty tree pit outside our door, planted an indigo bush, moved a sumac from the planter, planted bulbs I had bought, and echinacea Marisa brought. We also replanted the planter with grasses and wildflowers. We made hand-made signs espousing our love for our human and plant neighbors, and took a tea break served off the back of a wagon. It was hard work and fun — and it was the first time since the pandemic that I had seen so many of my neighbors together. Now this tree pit that Ricardo and I had tended as a household in the past became truly a shared space, stewarded by our building and with our neighbors down the block.

Overall, we have an over-reliance on, but under-resourcing of civic stewardship groups in frontline communities. A “both/and” approach is needed to support an equitable system of stewardship across public, civic, and private sectors. The public sector provides crucial parks maintenance workers as paid jobs–and is currently facing devastating losses to this essential permanent and seasonal workforce in light of budget cuts.

Volunteerism and civic leadership also provide important sources of personal meaning, community contribution, and social ties, particularly in these times of high unemployment and underemployment. Vibrant urban public open spaces require government and NGO programs that enable and foster civic engagement at all times of year and in all neighborhoods.

Our public landscapes have the capacity to absorb so much of our personal trials and our societal tribulations. But it is active stewardship that can, at its best, transcend politics and build trust between people. When we have trust in each other, we have hope. Reflecting on the experience of everyday people during our nation’s hardest times in the 20th Century, NYC-born Studs Terkel once reminded us, “Hope springs up, it doesn’t trickle down.”

Rah! Rah! for Rail: Solving Transportation in Cities

Many voices. Greener cities. Better cities.

A review of Rail and the City: Shrinking Our Carbon Footprint While Reimaging Urban Space, by Roxanne Warren. 2014. ISBN: 9780262027809. MIT Press, Cambridge, MA. 336 pages.

rail and the city coverLike a dog with a bone, some of us just can’t let go of the notion of rail in cities. I’m certainly one of them. Since most cities dedicate more than 50 percent of their land area to transportation, and for 100 percent of contemporary cities, the majority of that space is dedicated to the almighty automobile, it is difficult to imagine how the nature of cities gets much better without dealing with the car. And it is easy to see electric rail systems as a compelling alternative, speeding us along green rights-of-way that lead to quiet, mixed-use, work/residential neighborhoods, with access to new spaces for playing and relaxing. One can see cities striving for these idyllic biophilic combinations in Europe and parts of South America, even in Asia, but the arguments put forth by numerous authors from diverse perspectives (myself included) have fallen on deaf ears for generations of Americans, who have found the combination of oil, cars, and suburbs more compelling still.

The most recent person to gnaw this particular femur is the New York City architect and light rail advocate, Roxanne Warren, in Rail and the City: Shrinking our Carbon Footprint While Reimagining Urban Space. Warren bites deep into what she calls the triple tyrannies: traffic congestion, dependency on petroleum, and paved environments. She shows that these three tyrants are mere henchmen at the beck and call of the American emperor pro temp: the automobile. Warren shuttles us through seven chapters that take on various aspects of why the car is bad (urban sprawl, pollution, space requirements, climate-changing pollution) and why trains are good (more space efficient, more energy efficient, better for healthy lifestyles, better for the disabled and elderly).

A long-time leader in “Vision42”, a fascinating proposal for a Manhattan light rail line extending across the island from river to river along 42nd Street (and possibly circling back via a loop along 34th Street), Warren knows well the pros and cons of what she writes. Reading her book, I feel like I can hear her in the offices of New York City politicians, or speaking before community groups, or honing the case with her rail friends at conferences, reinforcing her case emphatically and drawing the links between transportation and land use, land use and quality of life. The advantages for urban railways are manifold: less air pollution (including carbon dioxide, as suggested by the subtitle); more available space; less noise; complementarity with walking and bicycling; and the potential to encourage renewable energy. But still, most people don’t get it.

Warren argues that change is on its way, if incrementally, and we should not lose hope. She points out that streetcar mileage has actually been increasing in America over the last few decades (though not in New York City, where the rail du jour is the subway), and that there appears to be a shift in attitude as millennial Americans are opting for car-sharing schemes and urban lifestyles with greater appetite than previous generations. “Flexibility and mobility” [she quotes Richard Florida] “are key survival principles of the modern economy.” She sees what I see and what many others have seen before: that streetcars and light rail systems can provide exactly what’s required to maximize space and minimize energy consumption, as long as the cities around them are built with sufficient density and diversity to support rail travel.

Mixed use and density are not a problem in Warren’s New York. In fact, the main obstacle to light rail in cities, or indeed any form of shared transportation, is that Americans love their privacy and hate the additional governmental cost of public transportation. For all of us who appreciate the benefits of rail in cities, perhaps we need to adopt a new tactic that focuses on interests, not positions. Our interests are in shrinking our carbon footprint and making cities better, not the advocating for or against any one technology. In this light, the part of Warren’s book I found most thought-provoking was a short passage about autonomous cars.

Autonomous cars are not something I wrote about in Terra Nova: The New World Without Oil, Cars, and Suburbs (Abrams, 2013), which covers much the same ground as Warren’s book, nor something that Richard Gilbert and Anthony Perl wrote about in Transport Revolutions: Moving People and Freight Without Oil (New Society Publishers, 2010), another volume in this vein that I highly recommend. Warren dismisses self-driving cars as just the latest continuation of the space-hogging habits of the vehicles we drive ourselves, but I have begun to wonder if she, or the rest of us rail advocates, should be so hasty. If self-driving cars were electric, they would have the same benefits as light rail and other electrified rail systems, pushing the emissions out to the power plants where they could be replaced by renewable, non-polluting sources such as wind and solar. Warren points out, and autonomous car advocates are fond of telling, that most cars spend 96 percent of the time doing nothing, sitting around filling space that otherwise could be more profitably used. If urban Americans shifted from car ownership to car-sharing, on an “Uber” type model, with self-driving cars that we call up by app, then we would need many fewer cars (by some estimates 40 percent fewer). Fewer cars would mean fewer roads and parking lots and less traffic congestion. And if computers are doing the driving, autonomous cars could move closer together in platoons, perhaps even hitch together, without needing that psychological cushion space that human drivers require. Costs go down because there are no railways, just the streets we have today, and acceptance goes up because not only is it faster, quicker, quieter, cheaper (no car insurance required) and more fuel efficient, but also private.

In other words, is there a way to have all the benefits of rail in city without the rails? If so, then all of us who care about nature in the city should get ready for a ride.

Ramsar COP 13: What can Artists Contribute to Urban Wetland Restoration?

Many voices. Greener cities. Better cities.
Threats to wetlands include unsustainable urban development, pollution from cities, industry, agriculture, and invasive species, to name a few. But the biggest threat is one of perception.
The Ramsar Convention (also known as Convention on Wetlands) is the first of the major intergovernmental convention on biodiversity conservation and wise use. It was signed in 1971, in the City of Ramsar in Iran. This October, the 13th Ramsar Conference of the Parties (COP 13) will take place in Dubai, with a focus on “urban wetlands”.

The Convention has highlighted artists’ important roles in wetland conservation, having previously published Wetlands – an inspiration in art, literature, music and folklore. This document highlights a wide range of ways in which wetlands inspire artists, writers, poets, musicians and storytellers.

But why are artists involved? And what can they do?

In 1991, Artist Betsy Damon established Keepers of the Waters. Working with landscape architects and scientists in China (among other places) she helps us understand water as a living thing, building gardens that use a transparent, natural processes of purification. Participatory science methods underpin Brandon Ballengée’s studies of malformed amphibians in wetlands, resulting in peer reviewed papers and installations in galleries and museums. Artist Jan Mun works with bioremediation companies to grow mushroom fairy rings, absorbing oil industry pollution in New York.

These are three brief examples. There exist countless more, and ecoartscotland is out to find and highlight them. In support of upcoming Convention on urban wetlands, we will be using a hashtag #art4wetlands, to highlight a wide range of examples of artists working on conservation and wise use.

Art: changing wetland perceptions & instigating actions

Despite our scientific understanding of their critical roles both for humans and other species, wetlands are still among the most widely threatened habitats world-wide. Threats include unsustainable urban development, pollution from cities, industry, agriculture, and invasive species, to name a few.

But the biggest threat is one of perception.

Wetlands are, to quote the Wildfowl and Wetlands Trust, “…misunderstood and undervalued by people, leading to a desire to replace them with more ‘useful’ and ‘productive’ options such as housing developments and agricultural land.”

Changing such “perceptions of value” is one of the typical roles we expect of art. Indeed, this is an important role.

However, there are also other, perhaps more direct ways that artists are involved with wetland conservation. Artists across all disciplines are now actively involved using their creative skills in support of projects to preserve, restore, and interpret wetlands. At the heart of many artists’ projects is changing perceptions of wetlands, not just by representing them beautifully, but through on the ground action, often framed as ecoart (ecological art) or ecovention (ecological intervention).

Over the next few months, ecoartscotland will be publishing examples from all six of the Convention’s regions (Africa, Asia, Europe, Latin America & the Caribbean, North America, and Oceania), specifically those which have to do with the topics of wetland pollution, biodiversity loss, and inappropriate development.

We have assembled a programme highlighting artists working in different ways on issues such as habitat restoration, pollution and biodiversity loss. Below is a sampling of highlighted projects in these areas.

Pollution

Waterwash ABC is a project on the Bronx River led by artist Lillian Ball which created an intelligent buffer zone to absorb stormwater run-off from a parking lot. The project also restored native habitat, engaged local communities, opened up public space behind private businesses, and installed educational signage showing how the remediation works.

Jan Mun, mentioned in the opening of this article, worked within the Superfund site at Newtown Creek, a tributary of the East River and border between Brooklyn and Queens that has a legacy of industrial waste and pollution. Mun was supported to work with the Newtown Creek Alliance on the clean-up of oil industry pollution with a grant from the socially engaged arts foundation A Blade of Grass. Working with expert Paul Stamets, Mun used myco-remediation, mushrooms which absorb petroleum products and heavy metals. Artists have been effectively involved in various forms of remediation using plants since the artist Mel Chin—collaborating with Dr Rufus Cheney—was instrumental in the first field test Revival Field in 1991. Artists Georg Dietzler and Frances Whitehead have also done ground-breaking work on phyto- and myco-remediation.

Biodiversity loss

Also mentioned earlier in this article, Brandon Ballengée’s hybrid practice as a scientist and an artist underpins his Malamp project (1996-ongoing), documenting malformed amphibians and investigating the causes. This work involves participatory science through fieldwork in urban, suburban, and rural contexts across North America and Europe, resulting in peer reviewed papers in scientific journals as well as installations in art galleries. Ballengée’s eco-actions bring together groups comprising scientists and other interested individuals to participate in fieldwork collecting and documenting amphibians.

Urban development

As the largest threat to urban wetlands, you would clearly expect urban planners and architects to be at the forefront of protecting wetlands, but artists are also playing important roles from New York City, USA, to Chengdu, China.

The City as Living Laboratory programme has done extensive work on the potential for daylighting culverted urban waterways (including current proposals for Tibbett’s Brook). Many streams and rivers in urban landscapes have been closed over and now function as sewers and storm drains. Wetlands can absorb stormwater and slow it, reducing the likelihood of flooding where culverted watercourses once overwhelmed create more flooding problems.

Urban water is often polluted and opportunities to create urban wetlands to clean water are increasingly being taken as opportunities to also engage the public in a deeper understanding of water, pollution and their environment. The Living Water Garden (1998) in Chengdu, China, resulted from the artist Betsy Damon’s 40-year concern with water. The garden mimics a natural wetland process to clean a small proportion of the river water, and the process is clearly laid out through the sculptural forms so the city inhabitants come away with a deeper understanding of the function of wetlands. Damon’s work has been highlighted by Ramsar’s Culture Network.

Artists can bring together experts with communities in non-threatening ways, connecting up multiple ‘agendas’ including social justice and diversity with healthy water systems. Here, art plays a central role, engaging all sorts of people and demonstrating new and different ways of seeing and understanding our wetlands and our world.

#Art4Wetlands and Ramsar COP13

You can join the movement, by sharing your own examples of artists contributing to wetlands conservation and wise use with the hashtag #art4wetlands (If you are not on Twitter we are archiving the thread on Wakelet).

What should you tag? We are on the lookout for art in any artform that makes a difference, particularly new, perhaps little-known examples, particularly from Africa, Asia, Oceania, South America and the Caribbean.

The projects ecoartscotland is highlighting are changing perceptions on the ground, engaging experts and local inhabitants in practical and beautiful ways. They are contributing to our understanding of wetlands as well as to their health.

We look forward the stories, ideas, and inspirations that transpire over the coming months leading up to the COP13 urban wetlands conference!

Re-culturing an Urban Collective Ethos of Sustainability

Many voices. Greener cities. Better cities.
Dialogue focused on more sustainable and resilient futures, though necessary, is insufficient by itself. At its core, these movements must be driven by a new collective culture, shaped by normative ideals of equity, justice and sustainability.
In August 2017, I spent three days at the very stimulating Resilience 2017 conference, listening to conversations between nearly a thousand attendees—students, scholars, practitioners, musicians and artists—interested in understanding how we can craft a more resilient and sustainable earth system, one that keeps its people and its ecology in good health. The conversations at the conference were deeply thought provoking, and covered a range of issues—from using queer ecology to facilitate the blurring of the boundaries between science and policy, to ideas of how to link art and science in innovative ways for education. These topics, seemingly very diverse, had one common thread: the idea that our cultural connect with nature stands disrupted, and needs to be re-envisioned to shape a more resilient and sustainable future.

Nowhere is this more true than in cities. Cities contain incredibly dense combinations of people from very different social contexts, amalgamated in ways that they would never be in rural areas. This can produce cultural symphony, or cacophony! The breakdown of societal restraints on gender, caste and other artificial barriers, and the resultant opportunity to converse across boundaries, can stimulate great innovation and creativity. Indeed, many cities excel at this. But the unprecedented socio-economic heterogeneities and inequalities that we find in cities have also led to petty daily conflicts and riots, scenes of banal crime and horrific brutality. The often-lamented loss of urban connect between neighbours leads to a fragmentation of urban communities. Perhaps as a consequence, many cities have witnessed the rapid disappearance of urban ecosystems—with forests, wetlands, parks and lakes giving way to high rise apartments and garbage dumps. Provoked by the obvious deterioration, many cities are forging nascent efforts to develop new urban commons. In an urban context, this requires dialogue between communities and the State, as Sheila Foster’s recent research on the “Co-City” demonstrates. Yet dialogue, though necessary, is insufficient by itself. At its core, these movements must be driven by a new collective culture, shaped by normative ideals of equity, justice and sustainability.

This is particularly challenging in cities of the Global South—in countries such as India. In Mumbai, 10,000 families migrate into the city each month. By 2025, India may have the largest number of migrants in the world, of whom most will end up in cities. Some will be affluent, tech-sector workers. Many more will live in slums, often on very little. Yet across most sectors of society, levels of consumption are on the rise in India’s cities. This is clear by a casual look at the constitution of urban garbage in most cities for instance, choked with plastic—plastic that comes from the supermarkets and stores in the city that advertise and sell packaged toys, gadgets and even vegetables wrapped quite pointlessly in plastic film.

When a culture of conspicuous consumption overtakes cities, it subverts existing cultures. Many argue that India has had a “natural” affinity towards sustainability, with diverse faiths that consider nature as sacred. In cities such as Bangalore, sacred Ficus trees survive when other species are cut down to make way for infrastructure projects, for instance. But as urban settlements grow, so does the desire to convert a humble shrine under the canopy of a tree  into something larger. Thus many trees are enclosed within walls to build a small shrine, which slowly grows to prominence to become a large temple. The original tree, its branches trimmed and its roots enclosed, becomes weak and eventually gives way to the representation of sacredness in built form.

A sacred tree, with its branches heavily pruned, has given way in significance to the representation of sacredness in built form in the shrine below. Photo: Harini Nagendra

Urban water systems have also been subjected to this alteration in the nature of the sacred. Many religious festivals in India involve water. During the famous Durga puja season in Kolkata, tens of thousands of idols of Durga are purchased by individual homes and community associations, and later immersed in the city’s lakes and the sea. These were once small in size, made of clay taken from lake beds, painted with vegetable dyes, and then later returned to the same lake via immersion. Now, community associations compete to install larger and larger idols, which despite a ban are mostly made out of plaster of Paris, painted with toxic lead and mercury-based paints. When immersed, these idols pose a significant challenge to the same lakes that the Goddess is supposed to protect. Yet again, the normative core idea, of the worship of nature, has given way to a representation in very different form.

When I returned from Resilience 2017, in my home town of Bangalore, the Ganesha festival was just beginning. Worshipped as the Lord of Beginnings and the Remover of Obstacles, the Ganesha festival is an important one for many Indians. In Bangalore, as in Calcutta, the harmful environmental effects of submerging plaster of Paris Ganesha idols in the city’s already polluted lakes is well known. Yet despite a ban that has been in existence for the past 3 years, the streets continue to be lined with these idols. In recent years, there has been a growing citizen movement to encourage a return to “natural” materials—Ganesha idols made with wet clay, with grains and seeds, and other natural material. Many people that I know have now moved away from plaster of Paris idols to these natural materials, and indeed, they are becoming more visible on street fronts and in shops for sale, than in the years past. In my home, my daughter now uses the mud from our garden to make our Gauri (Ganesha’s mother) and Ganesha—we later immerse them in a bucket, and carefully pour the mud back into our garden, under the canopy of our mango tree. From earth to earth, this simple practice beautifully symbolises the cycle of life.

Yet overwhelmingly, the collective collection of plaster of Paris Ganeshas far outweighs those of natural materials—by a large amount. While many individuals have moved towards more sustainable practices, often motivated by conversations with like-minded friends, we continue to speak in silos. Most community associations prefer the artificial idols, being bigger, more colourful, and more conspicuous. And it turns out to be particularly difficult to have conversations with a motley urban collective, on seemingly waffly issues such as sustainability.

What does this tell us about the attempt to re-culture the urban commons, via a new collective movement? Changing culture is not easy—changing collective culture is particularly challenging. And yet this is the task we have at hand, if we are to engage in collective urban conversations about urban resilience and sustainability. Bangalore’s lakes, in which idols of Gauri and Ganesha have been immersed for centuries, now also host immersion of Durga idols, thanks to the city’s now substantial Bengali population—and act as sites for other festivals such as Chat puja as well, in response to migrants from other parts of the country. How does the city engage in conversations with each of these collective groups about sustainability? And yet—how can it not?

Informal settlements or slums provide a fascinating context within which to study the evolving culture of sustainability, for instance. As I describe in my book Nature in the City: Bengaluru in the Past, Present and Future many slums in Bangalore, though composed largely of migrants, have a high collective ethos of urban conservation, planting and carefully nurturing a wide diversity of species in cramped spaces, despite challenges of water availability. Indeed, the greatest proportion of native species we find in Bangalore is in its’ slums. The strong social ties between neighbours, and the high dependence on nature, seem to play a role in fostering this collective sense of sustainability. This may be more complex in wealthier residential communities, where many do not know their neighbours well.

The challenge of re-culturing a collective urban ethos of sustainability is profound, but essential, for urban resilience in the Global South. There are no easy answers. But equally, there is no escaping the need to make progress on this front.

On The Nature of Cities

Re-envisioning Cities Through Bottom Up Neighbourhood Planning, Not Top Down Master Planning

Many voices. Greener cities. Better cities.
A sustainable ecology of cities is possible when we successfully combine environmental and socio-economic dimensions equally in our plans and actions. In fact, it is the extent of their integration and inclusion that should form a criterion by which we evaluate our success.
If there is one thing that I have to state as being the most important learning from my living and working in Mumbai, it is the need for collective intervention to combat the current trend of exclusionary urban development with an objective of achieving social and environmental equity and justice for all. Also, as a necessary condition, each individual intervention should have to be linked to other larger democratic rights struggles, thereby building networks of interventions towards evolving an alternate vision of the city.

It is with this objective that I consider building relationships collectively between people and with nature as an important mission. This mission includes an understanding of such relationships and networks of interactions, particularly those that develop in the process of collective interventions by citizens on demands pertaining to social and environmental justice and how they contribute to the larger interest of sustainability of cities.

I would like to view cities from social and environmental perspective and understand how the two together constitute a necessary condition, and what their union means for the achievement of a higher state of sustainability. The two are inextricably entwined and neither is exclusive. Thus, a sustainable ecology of cities is possible when we can successfully combine environmental and socio-economic dimensions equally in the plans and actions that we pursue. As a matter of fact, it is the extent of their integration and inclusion that form a criterion by which we evaluate the value of our work and engagements.

Very often we find ourselves absorbed into zones of comfort and complacence, engaging in issues and places that have already been developed or achieved exclusivity. But to get out and engage with situations of instability and discomfort, dealing with the invisible yet perceived barriers across city landscapes, and their unification, is indeed challenging.

After all, what can be more equal between nations, influenced by neo-liberal globalisation, than the question of land mis-utilisation, exclusionary city planning, and the deplorable state of the environment in which vast numbers of people are discriminated and subject to climate change risk. It is for these reasons that the local struggles of the marginalised and discriminated people for equality and sustainability, across borders and nation states, are indeed global in their essence and spirit.

What we are deeply concerned about is the constant division of our cities into disparate fragments, both in social and spatial terms. Polarisation of people and communities in terms of their religion, race, caste, class, faith, gender, nationality is leading to social instability and tension. Indeed, our cities are producing and reproducing backyards of exclusion, discrimination, hatred, neglect and abuse; even natural habitats are being systematically destroyed leading to increasing levels of social intolerance and climate catastrophe, thus undermining the very idea of cities and their sustainability.

As these conflicts begin to dominate the city landscape, we are compelled to intervene, particularly on behalf of the excluded, discriminated, and much abused backyards of people and places that are, in most instances, situated in the borders, edges, peripheries, and margins.

Our discourses on cities have relied on the understanding of social relationships and how the modes of production have influenced their formation. In support this statement, I would like to refer to David Harvey and his book Social Justice and the City, when he quotes from Karl Marx: “The totality of these relationship of production constitutes the economic structure of society, the real foundation, on which arises a legal and political superstructure and to which correspond definite forms of social consciousness. The mode of production of material life, conditions the general process of social, political and intellectual life. In terms of Marxist terminology, the urban and the process of urbanization are simple superstructures of the mode of production (capitalist or socialist)”.

Further, in the same book, Harvey has analysed social relations, built form and environment and how each influences the other, but his reference to environment is restricted to built-environment and does not include the natural ecosystems. I quote: “Urbanism may be regarded as a particular form or patterning of the social process. This process unfolds in a spatially structured environment created by man. The city can, therefore, be regarded as a tangible, built-environment- an environment which is a social product.”

Interestingly, Pickett, Cadenasso and McGrath in their book, Resilience in Ecology and Urban Design, quoting McGranahan and Satterthwaite, present a much wider understanding of the environment. I quote: “A great deal of the urban sustainability literature tends to promote the so-called ‘brown agenda’ of environmentalism, which emphasizes the need to solve immediate needs of the billions of people who live in degraded, unsanitary conditions and grueling poverty, while the ‘green agenda’ emphasizes protection and enhancement of ecosystems to support future generations and other species. Reconciling green with brown agenda issues, however, is at the heart of more encompassing viewpoints on sustainability, recognizing that poverty and environment conservation are inextricably entwined (McGranahan and Satterthwaite 2002)”.

Such reconciliation is indeed the essence of the Irla movement, of which I am a part.

This phenomenon is realized in many world cities, more critically experienced in the cities of developing nations. While cities are expanding, public spaces are rapidly shrinking, in both physical and democratic terms. The democratic  “space” that ensures accountability and enables dissent is also shrinking—very subtly but surely. This means space for wider public participation and dialogue are shrinking. It is in these prevailing conditions that we are compelled to pursue the idea of public spaces as being the foundation of city planning. Public spaces ensure physical, social and democratic well-being of all. The city’s shrinking open spaces are of course the most visible manifestation, as they directly and adversely affect our very quality of life.

It is in this context, I consider our struggles to pursue the idea of unification of cities through architectural and design endeavors as being important; while engaging closely with social and environmental movements. Our priority has to be to establish close relationship between architecture and people, placing strong emphasis on participatory planning from the very beginning and at every stage.

A Mumbai example, with active participation of the author.

Through a neighbourhood-based development approach it is possible to decentralize and localize projects, thus breaking away from monolithic planning and design ideas that are disconnected from most people (and often serve the interests of the few, not the many). “Master Plans” for cities are generally top-down models, drafted by elite groups of designers, and fail to engage with citizens on their ideas.

 With localised projects, the planning of cities will hopefully become a bottom-up process with participation of all people providing opportunity for collective intervention. Importantly, neighbourhood-scale work is a more collaborative approach to the city and place-making. For citizens, such projects allow the immediate reclamation, redesign, and re-programming of public spaces within their localities.

Along with the promotion of neighbourhood plans it is necessary to develop city-scale sustainability ideas and plans and through that process evolve alternate vision for cities. Networking and unification of the various neighbourhood plans would be a good way forward.

It is neighbourhood plans that must form the basis of city planning. Such an effort requires a paradigm shift in the mindset of formal planning, obsessed with building barricaded mono blocks that divide and brutally fragment city landscapes, to include sustainable ecology and environment as the central aspect of city development plans, prepared with the objective of unification, with peoples participation right from its inception. It is for the fulfilment of this objective, not real-estate and construction turnover that constitute the predominant idea of successful development, that the rejuvenation and integration of the natural areas and open spaces with an idea of expanding public spaces ought to be set out as a mission. Intervention, integration and re-envisioning being a key strategy and effective instrument for bringing about the much needed socio-environmental change.

Re-naturing Cities: Theories, Strategies and Methodologies

Many voices. Greener cities. Better cities.
Although Brazilian cities have, historically, developed with a strong presence of nature, rapid and often uncontrolled growth poses serious risks to the environment and quality of life of urban dwellers.

There is strong interest in the theme of re-naturing cities, since “naturalizing” cities can help address multiple global societal challenges and generate benefits, such as the enhancement of health and well-being, sustainable urbanisation, the provision of ecosystems and their services, and resilience to climate change. But, what are the theories, strategies and methodologies that can be used to re-nature our cities? How can we plan with nature? What are the models and approaches that can be used to enhance the presence of high-quality green spaces in our urban areas? And how to move from theory to practice? These were essential questions debated in a four-day workshop organised in Goiânia, Brazil. Funded by the British Council and Fundação de Apoio à Pesquisa do Estado de Goiás (FAPEG), under the Newton Fund Researcher Links Programme, the workshop brought together policymakers and approximately 40 researchers from the UK and Brazil from a range of disciplines, such as urban ecology, town planning, biology, architecture, landscape planning and geography.

The workshop was a forum for transnational synthesis of knowledge on the topic and generated valuable insights into how academics, planners and policymakers could apply this knowledge to their cities and regions. All selected participants, coordinators and tutors presented their research. These included speeches by organisers Fabiano Lemes de Oliveira on his green wedges research and Pedro Britto’s on the social side of sustainability; as well as talks on urban agriculture by Silvio Caputo, the ecology of green roofs by Heather Rumble and the blue space planning of Goiânia by Karla Emmanuela. There were eight research sessions: Planning Greener Cities; Urban and Environmental policy; GIS, Building Information Modelling (BIM) and City Information Modelling (CIM) for Re-naturing; Blue Spaces; Ecology and Biodiversity; Climate Change and Resilience; Perceptions, Health and Wellbeing; and Between Formal and Informal.

Research sessions were complemented by development sessions on publishing and research methods, among others. Field trips informed participants of relevant case studies. A great strength of the workshop was the presence of representatives from the city of Goiânia and the different thematic groups prepared manifestos for re-naturing cities, which were then translated into spatial planning ideas for the city. Policymakers interacted and responded to the proposed strategies, which will inform the discussions for the revision of the Goiânia masterplan (Fig. 3). The following is a synthesis of each thematic group’s conclusions:

Planning greener cities

This session made manifest the need for considering urbanisation and nature together, the importance of proactive and positive planning, the definition of systems of interconnected green and blue spaces at multiple scales, the roles of communities in shaping their environment and the benefits of considering urban metabolism as a way to further embed the understanding of processes in spatial planning. A positive and systemic mode of planning has the capacity to integrate needs, potentialising the benefits derived from the different systems and resolving their pitfalls in an integrated manner. As such, Camila Sant’Anna called for a focus on hybrid landscapes, where the green-grey divide no longer exists. The overcoming of such dichotomy and the challenges of implementation were explored at the metropolitan scale by Julia Leite Rodrigues’ proposal for ecological corridors and green wedges for São Paulo, and at the city-scale by Karin Meneguetti in her application of landscape ecology principles to various cities in the south of Brazil. In order to move from planning theory to implementation, Ian Mell emphasised the importance of understanding the economic and social values of existing and proposed green infrastructure, as well as the assessment of policy. Daniela Perroti, in turn, explored how urban metabolism—understood as the sum of the technical and socio-economic processes that occur in cities, resulting in energy and material supply, growth, and elimination of waste—could present frameworks for the planning and designing of greener and more resilient cities. The session highlighted the need for a conjoined understanding of natural and man-made processes if we are ever to be successful in re-naturing our cities.

Urban and environmental policies

If we were to re-naturalise our living environments, understanding the different connotations of the term, local challenges and opportunities is crucial. How can re-naturalisation take place in an increasingly urbanised world? How can urban, rural and environmental policies be intertwined? José A. T. e Silva addressed these questions from the perspective of the Brazilian hyperurbanisation reality. He argued that, in a country where approximately 90 percent of people live in urban areas, the integration of different public policies needs to occur and be considered at varying scales for an effective improvement in the balance between urban and non-urban. From the legal perspective, Luciene Araujo highlighted that the relationship between city and the countryside ought to be considered in a systemic manner and that payment for ecosystem services and economic incentives for re-naturing ought to become mainstream practice. The session was marked by feeling that there is a problematic misalignment between Brazilian urban policies and the needs of re-naturalisation. Mariana Santos highlighted the frequent disconnect between planning and policy, in particular in regard to water resources. Glauco Cocozza closed the session speaking of the impact that policies and private land ownership can have on the fragmentation of urban green spaces and impoverishment of their ecosystem services, using Uberlândia as a case study. Final discussions centred on how economic and political actors, as well as effective public participation, could be interlinked and triggered to bridge the gap between reality and a greener future.

GIS, BIM and CIM for Re-naturing

An essential point of discussion in this session was how to employ computation and big data to deepen our knowledge of urban and natural spaces, as well as to better balance urbanisation and nature in our cities. Elena Cantarello, for instance, looked into quantifying the resilience of multiple ecosystem services and biodiversity in a temperate urban forest using Landis-II as a modelling tool, and also presented a cost–benefit analysis of ecological networks assessed through spatial analysis of ecosystem services using ArcGIS and Ilwis. Rômulo Ribeiro and Josiane Giesta called for the use of GIS as a way to enhance the precision of objective data collection for city planning and how the provision of BIM/ CIM training for planning officers can support the development of public policies locally. The theme of data collection and its use, but from a participatory, people-centred perspective was also discussed. Junia Borges proposed the use of crowdsourcing and Volunteer Geographic Information (VGI), leading to the creation of substantial databases that, in turn, would support decision-making processes. Combining objective and subjective data through a mixed-methods approach, Ying Li mapped people’s use of public spaces and their preferences in order to develop an assessment tool and design guidance.

It was evident that this is a growing field of research, with much potential to support evidence-based decision-making processes. The use of such tools for the construction of solid, openly available and retrievable knowledge about our cities and green spaces, if combined with a participatory, systemic and integrative planning approaches, could provide pathways for the construction of greener and more balanced cities.

Blue spaces

The planning of blue infrastructure has increasingly become a fundamental strategy to build resilient and sustainable cities. This session focused on water from four distinct perspectives: contemplative, memory, planning and technology. Deborah Cracknell looked into people’s psychological and physiological response to water landscapes, in particular aquariums, showing that these were at least as preferred and potentially restorative as green space. Mary Gearey explored how our connections to our intimate landscapes alter our perception of climate change impacts and our future lives together. She argued for the need to understand how local actors perceive and respond to changes in their local environment to help develop strategies and tools in support of sustainable futures. José Guilherme Schutzer called for drainage basins to be at the centre of regional planning. Lastly, Komali Kantamaneni focused on the role of technology in supporting resilient environments in face of extreme weather events. The multifaceted dimensions of blue spaces were central to the discussions held about the importance of further understanding the roles that blue spaces play for both the resilience of living beings and their environments.

Ecology and biodiversity

 Discussing contrasts between urban ecological research in the UK and Brazil, a biodiversity hotspot, was enlightening for all those involved in the Goiânia workshop. The city environment offers rich opportunities for ecologists; understanding the unique mix of organisms and how these can contribute to improving urban ecosystem functioning is key to renaturing. Recognition that cities can be a valuable habitat for many plants and animals is growing. It was quite apparent, however, that whilst some of the barriers and opportunities for urban colonisation were common between different geographical locations, some stark differences existed in terms of the perceptions of urban ecology and the mechanisms being adopted to promote biodiversity in cities.

Researchers from the UK capitalised on technology in cities, highlighting the potential of using green roofs, green walls, engineered soils and other green infrastructure to mitigate habitat loss. For example, designing green roofs and soft-landscaping using ecomimicry of locally important habitats was shown to generate improved remediation for habitat lost in brownfield development. Another theme was the need to frame urban ecological research in terms of the economic and societal benefits it can provide, the ‘ecosystem services’. In this context, brownfield sites were again, identified as a key urban habitat, given the potential of brownfield soils for capturing carbon through the formation of soil carbonates.

Our Brazilian counterpart, Fabio Angeoletto, described the challenges of urban ecology in Brazil, highlighting that nature is often thought of as occurring outside cities. The research being conducted in Brazil focused on collecting the detailed evidence needed to understand urban ecosystems and protect biodiversity, without applying an economic value. Fabio’s work spans from understanding the impact of domestic cats on city animals to trying to halt the reduction in nest sites for the blue and yellow macaw, Ara ararauna.

 We discussed that this latter approach, “reductionist” research, is often assumed to have been done in the UK, with pressure to produce more “emergent” research that is immediately applicable. But there is still much we don’t understand about urban ecosystems, limiting our ability to effectively apply ecological solutions. Thus, together, the approaches of UK and Brazilian ecologists, could provide effective strategies for renaturing, valuing nature as a tool to improve cities whilst capitalising on the inherent ability of nature to inspire us.

Climate change and resilience

The five presentations of this session covered a spectrum of approaches to climate change and urban resilience that ranged from technology-based solutions to enhanced stakeholder participation. Presentations focused on two particular aspects of climate change, namely, Urban Heat Island (UHI) and flooding.

The technology-based approaches to climate change and resilience include the use of modelling software, providing an accurate understanding of the physical factors triggering higher mean temperature, which was applied in a study on the area of Salford University campus. The same study presented several techniques for data collection, the equipment necessary for this collection and the appropriate scale of study. A second presentation focusing on the UHI, presented a case study in Leeds, which specifically examined the potential for mitigation of the greenery, demonstrating how trees are more effective than grassland. Finally, a presentation of an urban microclimate mapping project in Goiania demonstrated the value of developing long-term scenarios – through dedicated software – which can be used as tools to generate policies addressing negative impacts of the UHI.

Stakeholder engagement-based approaches included a study on a governance model of flood risk management, which puts at its heart local communities and the nurturing of people’s connectedness and risk awareness. Similarly, a case study looking at three South American border cities in spatial proximity, albeit each one in a different country, exposed the significance of cooperation and coordination across boundaries, which can lead to higher effectiveness of policies that are already, to some extent, addressing climate change locally.

The range of studies presented suggested that research in this area must integrate both approaches and explore solutions capable of merging engineered approaches with a deeper understanding of socio-political dynamics.

Perceptions, health & well-being

This session explored the influence on the level of urban well-being of several factors comprising the shape and characteristics of the built environment as well as the methodological approach to design interventions fit for purpose.

The connection between health and a fair built environment was illustrated in a study on some Brazilian cities. A fair city is one in which access to services, the provision of green areas and the quality of the built environment at large is available to all. The study demonstrated the connection between urban areas where equitable availability is lacking and threats to health, such as obesity.  The effect of the spatial configuration of places on people’s behaviour was clearly demonstrated in a study on three squares in Belo Horizonte, where the quality of walking was influenced by the design of such squares. The amplitude of open spaces, presence of water, biodiversity and climatic conditions were found to be key aspects that, in the perception of passers-by, improved the square’s attractiveness and urban value.

Other studies focused more on theories and approaches to enhance urban well-being. The first one emphasised the importance of embracing complexity to improve the well-being of communities. Interaction with green spaces, a recognised condition that can improve life quality, must be complemented with other factors such as physical activity and social interaction in order to yield multiple benefits. Embracing complexity also entails the hybridisation of theories and approaches on urban design well-being with those related to behavioural change and environment-behaviour. The second one reviewed theories that specifically connect nature with well-being such as biophilia, environmental psychology and ecological models of human health. It proceeded to review methodologies to ascertain this connection, based on statistics and ethnographic approaches. It finally presented a project focusing on the construction of an edible green wall in a school in Scotland, which put in practice some of the findings derived by the theories mentioned.

Between formal and informal

Although Brazilian cities have, historically, developed with a strong presence of nature, rapid and often uncontrolled growth poses serious risks to the environment and quality of life of urban dwellers. In this context, do formality, informality and in-between conditions lead to different pathways for re-naturing cities? How do such conditions forge our relationships with nature? What are the roles of policy and practice in situations where bottom-up meets top-down?

Veronica Donoso investigated social practices in social housing open spaces. Often in in-between conditions, these spaces were explored from their potential in redefining and being defined by people’s wishes, aspirations and relationship with the city in which they live. An historical perspective of the changing nature of what re-naturing meant for cities in the long run was brought about by Aline Silva, who presented an archaeology of historic gardens in Recife, João Pessoa and Fortaleza in Brazil. This was allied with a longitudinal study of tree species selection. As such, Silva correlated time-located ideological views of these landscapes with the choice of species. Fabiana Izaga explored the changing nature of informal landscapes in favelas in Rio de Janeiro. Large-scale events such as the World Cup and the Olympics impacted not only on the formal city, but also led to processes of transformation of favelas. Tourism has linked the visitors’ interest in the favelas themselves with their environment.

The often conflicting dimensions of places discussed in this session tend to point to conditions of varying hybridism, which must be understood for an effective, inclusive and positive transformation of cities.

Final remarks

The workshop culminated with the development of a manifesto for re-naturing cities and its application to the city of Goiânia. Given the collective nature and multidisciplinary ethos of the manifesto, the following key recommendations synthesise preoccupations and recommendations that can be applied to cities across the world:

  1. Efforts to re-nature cities must involve a proactive planning approach.
  2. The planning and implementation of networks of green and blue spaces must be systematically integrated into comprehensive planning frameworks.
  3. A shared understanding of the urban challenges and their potential solutions ought to be co-developed, alongside an inclusive approach to participation.
  4. We must take an evidence-based approach to re-naturing cities. This requires the collection of baseline data, monitoring and establishment of measurable targets that allow an actionable approach to urban biodiversity conservation, and ecosystem service provision.
  5. We must make the business case for the value of urban green and blue infrastructure by identifying and communicating the social, economic and environmental benefits at multiple scales to communities and decision-makers.
  6. The development of policy mechanisms to potentialise the re-naturing of cities needs to be developed and implemented in practice. This should include the definition of key baseline indicators and incentives for further re-naturing.
  7. Environmental justice for all must be an objective. This involves better understanding of how urban green infrastructure and biodiversity influence health and well-being, and policies aimed at overcoming inequalities regarding access to ecosystem services.
  8. Re-naturing is as much about a sustainable future as it is about a resilient one. Re-naturing strategies must aim at reducing cities’ environmental impact on the planet as well as offer mitigation strategies.
  9. New technologies and novel nature-based solutions for re-naturing cities need to be considered. This can range from the creation of scenarios using GIS that simulate the outcomes of proposals and policies, to the use of social media to garner public opinion and values, through to engineering soils to capture carbon and mitigate climate change impacts.

Re-Wilding: Cities by Nature

Many voices. Greener cities. Better cities.

The historic gardens of Western civilization typically include segments that were municipal areas, hunting grounds, or, on occasion, fragments of the region’s original forest. Many of the Italian, French, and English gardens that establish the history of landscape gardening were interventions added within or onto lands that, originally, were uncultivated royal reserves. While the architectural garden is typically what history records as advancing principles and concepts of landscape, architecture, and urban design, what is often overlooked is the importance of the uncultivated landscape that remained around the garden—or, in some instances, sections of it that were assimilated into Renaissance designs.

The idea advanced by re-wilding is the memory of a landscape type—a woodland, wetland, prairie—made manifest.

For example, what is typically known as the Villa Lante in Italy is a Renaissance garden set within a much larger natural preserve that was also owned by the founding Gambara family. Before political activities moved out of Paris to Versailles and it became a garden, the site served as a hunting lodge surrounded by an uncultivated forest. Likewise, King Henry the XIII originally acquired the area known today as Regent’s Park in London for hunting and leisure before historical circumstances began a process of transforming it from private lands into the public park that it is today.

The uncultivated areas of these gardens served as settings for hunting, horseback riding, and strolling with allies and adversaries—and as an intellectual counterpoint to the metaphors, abstractions, and narratives to the architectural gardens they supported. While the uncultivated segments may be less interesting to history and design students when compared with the architecturally elaborate gardens they complemented, the appearance of megacities and the intersection of their challenges with environmental issues provide reasons to reconsider a new purpose and potential for uncultivated landscapes.

“Re-wilding” is an emerging discourse within contemporary landscape design—an intriguing topic with possibilities and interesting issues. Where historic gardens made the natural reserves secondary and placed them in service to architectural gardens and their cultivated experiments, re-wilding offers the potential to make “wildness” the priority, putting the cultivated landscapes in service to UN-cultivation. What follows in this article is an overview of select terms, case studies, and examples related to the emerging topic of re-wilding.

Re-wilding: terms, definitions, and clarifications

Re-wilding describes a landscape design and construction approach that reestablishes and/or restores an area of land to an uncultivated state. It may also involve the reintroduction of species that have been driven out or exterminated by previous events; g enerally, however, re-wilding accepts that it is impractical, if not impossible to reestablish a textbook example of an “original” landscape and its ecology. Modifications to the reconstituted landscapes produce synthetic alternatives that avoid the trap and problem of ecologically achieving the original landscape.

All architecture—and landscape architecture, by extension—is fiction. Whether the fiction involves a narrative, metaphors, or abstractions, what separates shelter from architecture and landscapes from non-landscapes are ideas, shaped and constructed. The fiction advanced by re-wilding is the memory of an intended landscape type—a woodland, wetland, prairie—that is heightened by suppressing the appearance and evidence of human hands. Adding or including wildlife into the production, where possible and appropriate, further amplifies the design program and intention for re-wilding.

In any design work, appropriateness is an important parameter. Where contemporary landscape architecture enjoys the poetic potential that suggests metaphors of a wild landscape—such as wading grasses and native plants in an urban park—art is not the objective for re-wilding.

Re-wilding is a memory trope that drives establishment of a wild landscape, as close as the physical, urban, and ecological parameters will allow. In the same sense that an uncultivated environment performs multiple services, such as groundwater recharge, water quality improvements, and environmental cooling, the re-wilded landscape should offer the same potential. The addition and/or attraction of wildlife not only increases the ecological services that a re-wilded landscape can perform, it heightens and intensifies the intellectual presentation of the memory project.

Re-wilding also accepts that any such work is as constructed, engineered, and human-made as any other landscape trope that is concerned with the conventions of abstraction, transformation, ambiguity, and poetics. An encapsulation of the intellectual intent may best be explained through Simon Schama’s seminal work, Landscape and Memory.

Landscape & Memory—critical to understanding re-wilding

In his seminal book, Landscape & Memory, historian, documentary filmmaker, and writer Simon Schama introduced a compelling insight into the meaning and perceptions of landscape. “Before it can ever be repose for the senses, landscape is the work of the mind,” Schama wrote. “Its scenery is built up as much from strata of memory as from layers of rock.”

Landscape is a uniquely human phenomenon and activity. Its reality does not center on flora and/or fauna, but rather, in the associations that humans have tenaciously imprinted on nature and internalized in meanings, relationships, and emotions that are recalled through experience.

As a cultivated example, the fine lawn of an American front yard is the “memory” of an English garden and noble estate. In the example of an uncultivated landscape, the American Great Plains is a “landscape of venture” because American history and westward expansion imprinted and mythologized legends and events. To paraphrase Simon Schama: “The prairie has no awareness it represents progress and the future to American lore. But we do.”

A key to understanding re-wilding accurately is making clear that the objective is as much about memory as it is about reconstituting natural plant systems and animal species. Tapping into the memory and recall associated with a particular landscape type through a synthesis and adaptation of a “wild” landscape is the goal and intellectual intention.

The Sprint World Headquarters Campus: a case study for memory and re-wilding.

A significant 68-acre portion of the landscape architecture for the 212-acre Sprint World Headquarters Campus in suburban Kansas City was a first step towards what can be retroactively viewed as a re-wilded Konza prairie and wetland.

Surrounding a corporate campus of 21 mixed-use office buildings that are linked by seven elaborately designed garden quadrangles is a reconstituted landscape of Konza Prairie grasses and a 17-acre wetland that is located at the low-point of the campus topography. Because the interaction of 14,000 employees was to be concentrated within the habitable quadrangles, the seven landscapes are variations on garden metaphors. By contrast, the perimeter of the campus is a non-irrigated belt of prairie grasses and native plant materials that, after installation, have attracted coyotes, foxes, and several species of birds and waterfowl in the wetland and its preserved stand of timber.

Given that the corporate campus is situated within suburban Overland Park, Kansas —a southern suburban of Kansas City, Kansas—burning the installation twice a year to rejuvenate an academically authentic ecology wasn’t realistic or feasible. Memory and the “sense of prairie” became the actual goal and a workaround to the practical problems, which were solved by planting a modified mix of grass species that were adapted to mowing and to the invasive species that were present in the suburban context.

Applications for re-wilding and their benefits

Urban planning experts extol density, saying that “density offers hope”. However, suburban megacities are typically settled at exceptionally spare densities that make them virtually impossible to densify by conventional means. For example, the metropolitan area of Dallas-Fort Worth in the United States is settled at an average human density of one person per acre, as are other American cities, including Atlanta, Albuquerque, and Houston. Phoenix contains less than one person per acre. New York, Paris, and Hong Kong have densities well above 100 persons per acre. In some cases, during the workday, these cities reach densities of 500 to 1,000 persons per acre.

While the New Urbanism and urban planning examples of European cities provide potential planning methods that can apply to nodes, concentrations, and areas of greater agglomeration, they generally do not apply to the thin and diffuse geography of a suburban megacity. As a result, wildlife is beginning to emerge within suburban megacities, not merely as varmints and rodents, but rather as members of vertical food chains that include predators such as coyotes, red fox, bobcats, javelinas, and bald eagles.

Graduate programs in wildlife are establishing in suburban megacities such as Dallas-Fort Worth to study this new and expanding phenomenon. Taken together, the documentary evidence and the unassailable persistence of the emerging wildlife afford a new and originally unforeseen possibility to retroactively rationalize the low density geography of a suburban megacity as a new kind of phenomenon where civilization and wild life coexist.

In the formative history of the American suburb, the sparse density of suburban sprawl was conceived as a development pattern that could be rapidly proliferated. As a landscape character and image, the mowed lawns and clipped hedges of American suburbia merged dwelling with the nature of an Arcadian, English-like landscape. However, Arcadia requires cultivation: mowing, watering, and extensive resources for upkeep, which strain personal households and homeowners associations to sustain. Front yards, rights of way, and parks that were once seen as the fine lawns of a noble estate could begin to transform into a new and more practical landscape blending civilization and wildlife.

This is a profound and new way of reconceiving and restructuring suburban cities that also overturns the old urban paradigm juxtaposing cities with wilderness. The premodern paradigm is a two-dimensional construct that locates civilization, law, and culture inside a physical and psychological world that is protected from an uncivilized wilderness surrounding the city, outside. However, vague and blurred geographies of suburban megacities have allowed wild species the opportunity to take hold and even establish food chains. Whereas wilderness and nature were once a matter of “outside”, wild species are now rising as a new ecological layer within the city.

Using Google to search “Bobcat City” will link to a video produced by the Texas Parks and Wildlife Foundation that documents the study of urban wildcats (that is, bobcats) in the low-density geography of the Dallas-Fort Worth Metroplex. Related to this example and activity, The Dallas-Fort Worth Urban Wildlife Club and Face book page tracks and documents a daily record of other wildlife and species when they are spotted.

The shift from cultivated English landscapes, to the contemporary impulse for native plants and then, ultimately, carefully planned wild reserves within an incorporated city geography—a geography where birds, pollinators, predators, and others coexist with human civilization—affords an intriguing new way to live. That this possibility is materializing retroactively in suburban megacities, rather than as an intention that was part of the original suburban project, also holds the promise of shaping a sustainable future where children and generations grow up in a metaphorical “wild classroom,”cultivating an awareness and an immediate relationship with nature that could be a reminder about the human condition and its relationship to Earth.

The Dallas Trinity River project: a case study, re-wilded

Over the course of some 40 years, eight celebrated landscape architects and their firms have proposed design concepts to transform a half-mile wide, engineered floodway through downtown Dallas-Fort Worth into an urban park. Known as the Trinity River Project, the 7.5-mile long, 2,000 acre, treeless landscape formed by earthen levees of erosion-control grasses and pothole wetlands, teases the imagination with potential.

However, the floodway is also a hydrological bottleneck that concentrates stormwater runoff that is collected in several million urban acres upstream in Dallas-Fort Worth Metroplex. The practical demands generated by the floodway present a stupefying set of problems that no single design has yet to comprehensively solve.

When the expansive floodway is brimming from levee to levee with stormwater, the hydrostatic head and the flow velocity through the area has been measured at nine feet per second—a speed calculated by engineers as the frictional equivalent of a 177-mile per hour wind or Category Five hurricane scouring across the flat and treeless landscape surface. Other collateral effects compound the impact of the current and flooding.

Expansive silt bars are deposited with each flood event. The June 2015 flood, which resulted from monsoon-like rains that lasted for over one continuous month, deposited silt bars approximately 20 inches deep over jogging trails and walkways, as well as Trammell Crow Park, a small pond and respite built in the late 1980s. In addition to the silt bars, enormous trash snags tend to accumulate around and between the piers of several vehicular bridges that cross the floodway. The agglomerations of plastic bottles, driftwood, suburban toys, and other sharp objects brought into the floodway can grow to several acres in size. The debris presents a formidable problem for maintenance, upkeep, and the related costs to accomplish it. Recently, silt bars created by the June 2015 flood rendered the area’s trail system and its attendant parking lots unusable for over a year.

Beyond to observable debris, environmental experts point out that the incoming stormwater flow is rich in concentrated urban toxins that become incorporated within the silt layers. As an expert cleverly explained at a symposium on the Trinity River, the floodway is a clever “self-healing landfill” that safely encapsulates the toxins within countless layers of silt that naturally form after each rain event.

Setting the hefty demands of this landscape aside, what observers see today is a landscape that resembles a grassy marsh with wading birds, waterfowl, coyotes, red fox, and other wildlife drawn to the area by its ecology and the food sources it presently offers.

A concept known as the “Balanced Vision Plan” has been prepared for the landscape by WRT, a renowned Philadelphia-based landscape and planning firm; it has achieved federal approval by the U.S. Army Corps of Engineers. Founded by the legendary landscape architect Ian McHarg, over seven or so years of work, public meetings, and design, WRT developed a solution for Trinity Marsh that included naturalizing meadows; wetlands; active recreation fields organized by a chain of lakes and marshes; and a network of trails, paths, and accessible parking that ties it all together.

Thus far, WRT and their team of consultants and engineers have advanced the technical documentation and specifications for this project to a 35 percent point of completion. Sixty-five percent of the process remains to complete before the project can be publicly bid for construction.

As the project awaits authorization to proceed, a group of former City Council members, conscientious activists, and civic enthusiasts have come forward to laud the virtues of the Balanced Vision Plan and also to use the documentation work that remains to be done as an opportunity to heighten the naturalizing systems the BVP includes into a re-wilding project.

Recently, a second plan for Trinity Marsh has emerged through the support and backing of Dallas patrons. It is championed by Mayor Mike Rawlings and designed by the world-renowned New York firm Michael van Valkenburgh and Associates, or MVA. The MVVA plan concentrates on a 250-acre area in the immediate vicinity of two iconic bridges that were designed by another famous engineer and architect, Santiago Calatrava.

The MVVA scheme features a sophisticated work of landscape architecture that is purpose-designed and hardened to handle the formidable flooding demands of the Trinity. The proposal extends several other waterfront projects and accomplishments by MVVA in New York and the U.S. MVVA also designed the landscape architecture around the George W. Bush Presidential Center at Southern Methodist University in Dallas, designed by Robert A.M. Stern.

WILD DALLAS. Image: D Magazine.

Recently, D Magazine, a regional journal published monthly that covers cultural topics and is widely read by an educated business and corporate population, devoted an entire issue , “Wild Dallas”, to the topic of re-wilding the Balanced Vision Plan. The March 2017 journal included several articles by contributors to the design, renderings, and paintings of what the area would look like as a Nature Project. In coordination with the issue, D Magazine also sponsored a conference in uptown Dallas.

Conference experts included Dr. Robert Moon, renowned master gardener and caretaker of the venerated Nasher Sculpture Center Garden; Tanya Homayoun of the Trinity River Audubon Center; Becky Board, member of the Dallas Parks and Recreation Board; and myself. Former City Councilwoman, Angela Hunt, spearheaded the conference and the effort to implement the WRT Balanced Vision Plan as a re-wilded nature reserve that will be within walking distance of downtown Dallas.

Re-wilding as redefinition

As contemporary landscape architecture converges on ecological and environmental interests, re-wilding offers a new kind of expressive potential for design by redefining how the landscape will perform, and as what. The goal of re-wilding places equal emphasis on the accommodation of a wildlife program with the human condition that it will serve. The first step is to establish re-wilded, synthetic nature that is as close to the original as is practically possible. Then, design to put people into the re-wilded area in such a way that the two can coexist.

In this light re-wilding poses no threat to, nor is it a critique of, artful landscape experimentation. Paths, benches, and pavilions can easily fit into a re-wilded space and can designed with an artful hand. However, artful indulgence to stylize the embankments of a wetland levee, for example, would be an interference with the intended landscape character of a re-wilded wetland.

Given that any design hypothesis can be taken to an extreme, re-wilding should be viewed as a particular approach to naturalistic design that pushes beyond metaphors and abstractions to approach reality as closely possible. Metaphors, which can be powerful when skillfully employed in landscape architecture, exist only as aids—secondhand conditions for a real, factual reconstitution of an original landscape.

Re-wilding should be prudently considered and understood through the lens of two irreducible issues. One is appropriateness; the site, program, and location for where re-wilding might be considered. Secondly, re-wilding fundamentally requires considering the designing for a program of wildlife as equally important to designing the landscape as a place that can be inhabited by people.

With respect to appropriateness, for example, the prairie grass installation around the Sprint Campus in Kansas City establishes a landscape of memory that could attract wildlife—none were deliberately introduced into it. An academic reconstruction of the Konza prairie wasn’t practical, since the fire required to rejuvenate the original species, along with the invasive suburban species it would have been susceptible to, required an “adjusted” plant mix to be resilient and practical. After 15 years, thick stands of wading grasses have attracted coyotes and red fox. Several species of raptor are frequently seen plunging into the grasses for the shrews, field mice, and voles it also contains—an activity that only heightens the memory trope rising from within the campus: the original landscape.

Rather than conventional modalities, which are driven by theory, technology, or personal design style preferences, re-wilding offers an intensely performative landscape that takes the notion of naturalism to an extreme. Re-wilding is not a postmodern retrogression, receding from the future and the uncertainties it presents. Going forward, I am intrigued to observe and participate in re-wilding’s development and proliferation as an organizing concept in landscape architecture.

Introduction

We have assembled a list of 90 must-reads on cities from a diverse group of TNOC contributors—a nature of cities reader’s digest. The recommendations are as wide-ranging as the TNOC community, from many points of view and from around the world. They are a reflection of the breadth of thought that cities need. And, as my grandmother would have said: “This will keep you off the street and out of trouble”.

The prompt seems easy, but it turns out to be difficult to recommend the one thing everyone should read on cities, and what we have created here is a remarkable and diverse reading list. You will likely think of other essential works yourself, and when you do, leave them here as a comment. There is a rich conversation to experience simply by exchanging ideas on great books.

The list below could serve as a wonderful primer for courses or other gatherings. You can download the entire list as a PDF here.

Check out these titles at your local, corner bookstore. But if you choose to buy one of these titles online, please click here to go to Amazon. Some of the sales price will benefit TNOC.

The books are listed in a random order. Refresh your screen to see the list displayed in a different order.

Rambunctious Garden: Saving Nature in a Post-Wild World
by Emma Marris
2011, Bloomsbury USA

Touches critically on so many debates in ecology (well, in many quarters they are not debated). Re-wilding, novel ecosystems, are invasive aliens always bad, old conservation models … etc. Her writing feels effortless and then she gives you lots to kick back against. Rather like finding yourself eating an exotic flavour of ice cream (ice cream—yum, popcorn flavoured—gosh!).

Cities and Natural Process
by Michael Hough
1995, Routledge

Nobody concerned with urban habitat should miss this book, available in English and in Spanish, that reaffirms the role of nature in the city. In six easy to read chapters, landscape as a process is highlighted and understood as the link between nature, humans, and built environment. The author demonstrates that total control (of nature) is impossible and that in attempts to do it, the result is least diversity for the most effort.

Horizon 101 – Reflections and Paintings
by Jala Makhzoumi
2010, Dar Onboz

I strongly recomend Jala Makhzoumi’s “101 horizons”, for students and people involved in Landscape in cities as a fundamental reading to see a different point of view.
From a room with a view of the Mediterranean, in an artistic and emotional story, with poetry and illustrations, and also … blank spaces, Jala describes a Landscape where all Theories and Methodologies are surpassed by the day to day of a terrible and seemingly endless war. Despite all the fears, Jala paints, draws, dreams, wishes … expressing from her soul, so that we can understand the depth of this moment.

Efficiency and Harmony: Principles and methods of urban system regulation and control
by Rusong Wang
1988, Hunan Education Publisher

Rusong Wang is an internationally renowned urban system ecologist, whose work laid the foundation of urban ecology research in China, and influenced and contributed greatly to the theory and practice of eco-city development in China. Although not always highly cited in the English literature, some of the concepts and thoughts presented in this book—e.g., cities as complex social-economic-ecological systems—were inspirational in the 1980s and are cutting edge even today. Nominating this book is also a way to pay tribute to a fine urban scholar and his achievement—he passed away in 2014 at the age of 67.

The Death and Life of Great American Cities
by Jane Jacobs
1961, Random House

It opens up a view of the city as an ecosystem. It is a must read for anyone combating the “hot planning topic of densification”. Such an agenda builds, to some degree, on Jacobs’ thinking—but with a selective interpretation of it. She was one of the first describing how social capital is built in neighborhoods in large cities, and one of the first describing how the gentrification process works (but long before any of those terms were theorized). She lacked an understanding about the benefits humans obtain by interacting with natural environments, which is her drawback. But hey, no one is perfect. Great book, great humanist, and great systems thinker!

Hungry City
by Carolyn Steel
2008, Random House

Food fundamentally shapes our cities’ ecologies, economies, and social lives, but most people hardly ever consider how it reaches our plates in cities. Hungry City traces food from farm to fork and beyond. It will not only make you look at food in a new way, but will give you a new perspective on cities; as Steel herself says, “In order to understand cities properly, we need to look at them through food”.

The Works: Anatomy of a City
Kate Ascher
2007, Penguin Press

Kate Ascher introduces this portrait of urban infrastructure based on New York City with a wise observation: “Rarely does a resident of any of the world’s great metropolitan areas pause to consider the complexity of urban life or the myriad systems that operate around the clock to support it.” She then offers a richly illustrated compendium that explains five systems: transport of people and freight, power, communications, water, and sanitation. While slightly outdated due to the absence of a current description of today’s technology, it is an accessible and informative primer. The final chapter, “The Future,” lays out key concerns.

The Ecology of a City and its People: The Case of Hong Kong
by S. Boyden, S. Millar, K. Newcombe, and B. O’Neill
1981, Australian National University Press

This is a classic book in urban ecology that examines the city from an ecosystem perspective, with humans as a key and integral component of the ecosystem. In the 35 years since the book was published, Hong Kong has changed dramatically in many ways, including a 40 percent increase in population size and skyrocketing rates of consumption—this book provides a fascinating source of perspective in light of these changes. While some of the specific conclusions may well be unique to Hong Kong, the general patterns are largely applicable to growing cities worldwide.

Stories from the Sandstone: Quarantine Inscriptions from Australia’s Immigrant Past
Peter Hobbins, Ursula K Frederick and Anne Clarke
2016, Arbon Publishing

This newly published book is an archaeological-historical investigation of rock inscriptions at Sydney’s former Quarantine Station (1835 – 1979). It charts stories of new arrivals to Australia and the diseases that saw them held at this place for days, weeks, and months. I recommend it for its multiple narratives of the growth of Sydney as an urban, ethnically diverse, and spectacular city from immigration and medical perspectives.

Crabgrass Frontier
by Kenneth Jackson
1985, Oxford University Press

Because to understand the city, we have to understand the suburb. While conditions have changed since this 1985 book, Jackson investigates the role of multiple forces, including technology, transportation, federal policy, culture, and demographic shifts in shaping the suburban form of the United States. I read it as an undergrad in my first geography course, and this book sparked my interest in studying urban planning and later human geography.  Particularly insightful is his chapter on early federal policies—such as the Federal Highway Act, Home Owners Loan Corporation (origin of redlining), and the Federal Housing Act, showing the institutionalized roots of spatial unevenness and inequality in our urban and suburban form.

thecityinhistoryThe City in History: Its Origins, Its Transformations, and Its Prospects
by Lewis Mumford
1961, Houghton Mifflin Harcourt

There is no book like this in addressing how and why cities evolved, from the medieval villages to the modern post-industrial metropolis. Mumford was among the few able to grasp and communicate, through a clear and extraordinary narrative style, the very “nature” of cities, explaining the root causes of the processes which remain at the forefront of urban studies debates. His half century old insights explain most of the problem we’re still facing and about which any reader could deepen her knowledge with hundreds of books. But no other book could provide you the big picture, the bases for understanding “what is a city”.

Preludes
by T.S. Eliot
1911

Now more than 100 years old, this poem is a haunting look at a turn-of-the-century city, which—despite its description of a London where cab horses “steam and stamp” and lamps must still be manually lit—is shockingly modern. In a smoky, densely populated city, nature lingers, clinging uneasily, with “sparrows in the gutters” and vacant lots offering fuel for fires.

Banaras: Making of India’s Heritage City
by Rana P.B. Singh
2009, 
Cambridge Scholars Publishing

Based on more than three decades of intensive research and intimate acquaintance with the sacred geography and urban cultural history of India’s ancient living city, Professor Rana P.B. Singh, in this pioneering volume, provides an excellent narrative of the making of Banaras—also known as Kashi or Varanasi. This book is a lead reference for understanding the cultural landscape, sacred geometry and cosmogram, archetypal architecture, vivid ritualscapes, and magnificent riverfront heritagescapes of Banaras that portray and maintain the dignity of India’s rich history and culture. This splendid volume also serves as a role model for the multidisciplinary studies of urban cultural landscapes in South Asia and beyond.

Housing Without Houses: Participation, Flexibility, Enablement
by Nabeel Hamdi
1995, Practical Action

Hamdi focuses on participatory planning as an essential component of sustainable development, with local communities at the forefront leading discussions and contributing to the production of neighborhoods in cities. The failures of the state and market forces to provide housing have been demonstrated in numerous cases, and the book discusses how architects and designers along with citizens are responsible for building just cities. Hyper-local knowledge of local citizens is an incredible resource that architects can tap while making their cases for production of neighborhoods. The book also emphasizes how local bodies need to work in unison with state powers to promote equitable development, with a balance of new production and preservation of cultural aspects of daily living. The traditional roles of architects need to be challenged and evolved in order to develop strategies for development from the ground up in today’s context. This is a must read for all!

From Urbanization to Cities
by Murray Bookchin
Revised ed. 1996, Cassel & Co.

I think his reflections on cities and urbanization deserve much more attention that has been devoted to them so far. A few reasons:

1) Bookchin pioneered the analysis of urban ecology and political ecology from a critical viewpoint. His book Our Synthetic Environment (published under the penname “Lewis Herber”) was published a couple of months before Rachel Carson’s Silent Spring; probably due to the fact that his analysis is much more radical, Rachel’s book turned into a bestseller, while Bookchin’s book not…

2) Bookchin’s books The Limits of the City (1974), Post-Scarcity Anarchism (essays written between the mid-1960s and early 1970s) and, above all, Urbanization without Cities (1992) are as important or even more important than Lefebvre’s The Right to the City and The Urban Revolution—but everyone talks only about Lefebvre, who was in some regards not as profound or original as Bookchin.

3) Bookchin’s “social ecology” is a very important framework for the type of analysis we need in the 21st century.

Ecocity Berkeley: Building Cities for a Healthy Future
by Richard Register
1987, North Atlantic Books

The first book with “ecocity” in its title and perhaps the key text of the ecocity movement, this slim volume describes a vision of Berkeley (but it could be any city) as a place of wildness and life, dense with vegetation and people but empty of cars, with a narrative propelled by exuberant enthusiasm and a kind of wild-eyed joy that is rare in city literature. From buildings covered with trees and vegetation to precarious glass-bottomed walkways, recovered creeks, and cars converted into planter boxes, this is the book that let loose many of the memes that now populate city disourse and urban design. Neither conventionally academic nor stiflingly professional, Ecocity Berkeley is richly illustrated with naive and quirky drawings that help communicate sublime and sophisticated ideas about fitting a city within the full embrace of nature—read it alongside Murray Bookchin’s Limits of the City for a radical social and political analysis of urbanisation and the incomparable Lewis Mumford’s City in History for a comprehensive overview of cities that, like Ecocity Berkeley, remain absolutely pertinent to understanding that we cannot make a healthy future without balancing our cities with nature.

Cities for a Small Planet
by Richard Rogers
1998, Basic Books

In this book, Richard Rogers speaks to everyone: no matter the reader’s level of experience in urbanism and architecture, Roger reels in his readers, who in exchange are taken on a journey through the history of urbanism, urban decay, ecological design, and ultimately, humanity. This book is a potential classic in urban literature, and a fantastic entry point for beginners, or a recap for specialists, to contemplate the role of our cities and their potential for being a driving force for greater sustainability.

Global Cities: A Short History
by Greg Clark
2016, Brookings Institution Press

The book gives a very interesting overview of past waves of globalisation events and the formation of city networks going back 4,000 years, up to the patterns and processes underlying today’s globalisation and formation of large city networks.
The book ends with an analysis and discussion of the globalisation and cities of the future. Although there are vast differences between the networks of cities along the ancient Silk Roads and the 21st-century system of global value chains and competitive advantage, there are also striking parallels. The author argues that the leaders of today’s cities can learn much from how those in previous waves built and sustained their competitive attributes, and how to avoid becoming locked into unsustainable or unproductive cycles of development.

Sharing Cities: A Case for Truly Smart and Sustainable Cities
by Duncan McLaren and Julian Agyeman
2015, MIT Press

Everyone should read this book because it makes a case that the guiding purpose of the future city should be understanding the whole city as shared space, and acting to share it fairly. It brings together the notion of the city as a commons with a critical perspective on the sharing economy. Its compelling theory and a rich mix of city cases move the conventional smart city discourse from multinational companies driving city change, to technological innovation in the service of social innovation and well being for all urban dwellers.

Very easy to read for everyone, this book shows how real urban life takes place in the streets. A livable city is one that considers the human dimension and offers a friendly and safe environment. The book, available in English and in Spanish, gives many useful recommendations for planning and management.

Design With Nature
by Ian McHarg
1969, Natural History Press

Written in the 60s, it could be seen as very outdated—most of the ideologies are largely realized and the methods are practiced. However, it is still relevant for anyone who is interested in humans’ relationship with nature and how can we improve it.

L’anima dei luoghi: conversazione con Carlo Truppi
by James Hillman
RCS, Milano

L’anima dei luoghi (The Soul of the Place) is the transcript of a dialogue between the psychologist James Hilmann and the architect Carlo Truppi; it is aimed at understanding the profound identity between culture and nature. The nature of the place is rediscovered as a new subject of reference that has to establish new relations of meaning and to change human perceptions. To respect a “territory” by protecting it ecologically, instead of destroying it, means allowing its energy to live, to survive over time, and to come down to us. Hilmann’s perspective shows us how geographic coordinates can be seen as an expression of the soul of the place, and it also explains how in the same place, churches of different religions, and villages and cities of different ethnicities and culture, have given rise to a stratification of signs and memories. The book has not been translated to English.

Triumph of the City: How Our Greatest Invention Makes us Richer, Smarter, Greener, Healthier, and Happier
by Edward Glaeser
2011, Penguin Books

It is a well-written, comprehensive paean to cities of all kinds across the world. It is also full of insights and policy prescriptions which, whether one agrees with them or not (and there is much I disagree with), challenges assumptions about how and why some cities succeed and others falter. A terrific read for our urban era in which cities will play an outsized role in economic life, politics, and culture.

Greening the Red Zone
by Keith Tidball and Marianne Krasny
2013, Springer

I love this book. It shows how communities can take up greening actions as a means to regenerate their areas and reconnect communities with the past and the future. With case studies around the globe in cities that experience devastation because of natural disasters or wars and conflict, the book shows how nature in cities can restore identity and reignite hope for the future.

Swifts in a Tower
by David Lack
1956, Methuen

Everyone dealing with the ecology of cities should read this, wherever you are in the world. David Lack was a great ecologist and a great writer who produced a wonderful story about the swift, explaining the intricacies of its life in amazing detail and especially its adaptation to city life. His book is a classic in the literature of urban ecology. We all need to understand the detailed workings of urban ecology; there are so many mysteries. This book provides a way into that world that you won’t forget, and you will certainly look at swifts with new eyes.

The book is a good mix of research findings and narratives from locals about urban nature in an Indian city. It helps the reader to understand the various factors (colonial past, economics, poverty, development, etc.) that play a role in “what” and “how” urban nature is in the Indian sub-continent, and perhaps is applicable to many other cities in developing countries.

The Night Life of Trees
by Durga Bai, Bhajju Shyam, and Ram Singh Urveti

This is a hand printed, illustrated book that I turn to when thinking about trees in cities. It captures the luminous spirits of trees at night, as portrayed by the Gond tribe in central India, and communicates the intimate relationship between the people and the forest that goes well beyond simple functional dependency into a way of life and thought. It is a visual reference for how we can relink our imagination and culture with urban nature.

Al Muqaddimah
By Ibn Khaldoun
1377

In particular,  Chapter 4. Some modern thinkers view it as the first work dealing with the philosophy of history or the social sciences of sociology, regarding the evolution of cities. It is an attempt at critical thinking in 1377 AD; unfortunately, that AD-thinking is much needed in 2016 in our Middle East region, and perhaps even beyond. Of course, much of what it says is now not applicable, but the critical thinking methodology is remarkable for its time. Buy the book.

The Manhattan Project: Theory of a City
by David Kishik
2015, Stanford University Press

This book is the elaboration of a “hypothesis” that Walter Benjamin did not commit suicide at Portbou, but in fact faked his own suicide and successfully fled Nazi Germany. In the book, The Manhattan Project is his manuscript, discovered in the NY Public Library (after his actual death), which articulates a theory of a place and the ways in which the form of the city shapes us in situated ways. New York is seen as an urban implosion, deriving its power from increased density and diversity—the economic, artistic, environmental, and equity dimensions of this urbanist movement are explored in relation to works and worldviews of Mumford, Jacobs, Arendt, and a slew of other important thinkers. It is a playful and thought-provoking work that experiments with place-based, fictional philosophy in the urban context.

The Practice of Everyday Life
by Michel de Certeau
1984, University of California Press

…and specifically the chapter on “Walking in the City” in which he offers an “operational concept” that attempts to subordinate urban growth to user needs. While one of the primary references for his 1984 work—the World Trade Center—no longer exists and has certainly been surpassed in terms of largesse, de Certeau reaches ahead and amply problematizes extreme edifice for cities “founded by utopian and urbanistic discourse.” He reminds of the “tactics” required to navigate the contemporary city, and equally reaches back to LeFebvre’s “demand [for] a transformed and renewed access to urban life.”

The Culture of Nature: The North American Landscape from Disney to the Exxon Valdez
by Alexander Wilson
1991, Between the Lines Press

The late Alexander Wilson (a Canadian landscape designer and cultural critic) pre-dates Cronon in exploring the hierarchical dualisms that underlie our perceptions of nature in an urbanizing world. Wilson asserts that the environmental crisis is a cultural crisis, beyond the confines of landscape, which itself is full of deeply conflicting ideas about the natural world—and these are manifest most powerfully in our cities and suburbs. (For those who can’t access this out-of-print Canadian volume, you might go to David Orr’s [2002] The Nature of Design: Ecology, Culture, and Human Intention [Oxford Press] for related reasons, but that would be a second recommendation, so…. there.)

Urban Environments in Africa: A Critical Analysis of Environmental Politics

2016, University of Chicago Press

This book analyses power and resultant cityscapes through the Situated Urban Political Ecology lenses. Drawing on various examples from Africa, it reflects on how power shapes urban environments, leading to different configurations. Myers argues that urban African environments go beyond just power versus counter power to a structure of feeling—that assessing urban physical environments merely as sites of risks misses seeing these cities as wellsprings of environmental opportunities.

Small is Beautiful: Economics as if People Mattered
by E.F. Schumacher
1973, Harper & Row

An economic text for those in search of an economy that works for people and the environment, Schumacher’s treatise has been called one of the most influential books published in the past century. Based in the kind of socially and ecologically connected thinking where the well-being of people and cities sprouts from something more basic than sheer economic and industrial growth, the writing offers invaluable philosophical and practical wisdom for those looking to achieve the trifecta of social, economic, and ecological sustainability. Regardless of the discipline, every successful sustainability plan is bound to find its roots tucked somewhere in the theories of Small is Beautiful.

Karachi: Ordered Disorder and the Struggle for the City
Laurent Gayer
2014, OUP & Hurst

We were lucky, oh so lucky, to have Laurent Gayer explode onto the scene in 2014. Laurent works at Centre National de la Recherche Scientifique in France, but came to Karachi for several years to do this book, after having learnt Urdu in India. I believe his ability to conduct his interviews in Urdu, often shocking his unsuspecting subject, was the secret to the success of this granular examination of the forces that shape Karachi. Karachi has a rep for being the most violent city in the world (never mind that Oakland and Ciudad Juarez also once had a higher homicide rate). The violence was inexplicable; sure, experts had their theories, but none of them satisfied me. (I was working as the head of the metropolitan pages during some of its most violent years). What Laurent has done is explain “us”. His brilliant theory is “ordered disorder” or managed chaos. He explains why Karachi continues to function while falling apart every day. Best of all, it is a riveting read because he approaches it almost like a journalist and tells the story. Ordered Disorder is essential reading also for anyone who wants to understand the history of modern Karachi, how certain factors have influenced its growth, decay, and resilience, and how we often work “through” violence.

City Trees: A Historical Geography from the Renaissance through the 19th Century
by Henry Lawrence
2008, University of Virginia Press

What is mind-blowing in this book is the painstaking reconstruction of tree cover and parks in major cities from the 16th century on. It really changes your perspective to learn, for instance, that the Dutch practice of having trees along canals spread to trees along streets in Amsterdam, and that the initial response of most observers from other countries was bewilderment (why in the world would you want trees in a city?!). The book provides the detailed historical evidence that how we have tried to use nature in cities has changed and expanded multiple times since the renaissance, and (optimistically) could expand again even in our current urban century.

I have found Cradle to Cradle seminal in my development. It makes the critically important distinction between eco-effective and eco-efficient design.

Landscapes of Urban Memory: The Sacred and the Civic in India’s High-Tech City
by Smriti Srinivas
2001, University of Minnesota Press and Orient Longman

My book is set in the southern hemisphere, a fascinating account of how traditional and modern cultures, ecologies, and visualisations of the sacred and the civic influence each other, in the backdrop of the globalising city of Bangalore. It focuses on an iconic sacred event, the annual Karaga performance. Conducted by a traditional community of gardeners, the Karaga is organised around a network of garden and lake sites. Many of these sites have now vanished from the city, but survive vividly in memory and imagination, while others are still physically extant, though substantially altered in form and function. Through the lens of the Karaga, Smriti Srinivas describes the complex, changing matrix of cultural, political, and social ties to nature in an Indian city where tradition and modernity are two sides of the same coin. The book provides a scholarly insight into social transformations in a modern Indian city, but at the same time takes you deep into the lives and imagination of people in the city, describing how they see and value nature, and how this has changed over time. It’s one of my favorite books, on my favorite city. Happy reading!

Unlike the global village, which in its attempt to homogenize is increasingly exclusive, we understand that holistic villages, like the Campus WU, are the places that celebrate diversity and inclusion. Our actions can give form to holistic societies. That is our hope and a dream we want to share with all those who we meet along our way and which on the Campus WU was the common denominator and the holistic fire that united us before the proposed challenge. And so it was that on the back cover of the book Campus WU: A Holistic History, I wrote: “It is about the making of places that seek a dialogue with creation, with the hope of encouraging the people who experience our spaces to unconsciously perceive them. The reality is showing me that something magical happened in Vienna and that thousands of people allow themselves to be seduced by this utopia that became reality.”

Why? Because it addresses boldly, if impractically, the total dysfunctionality of the global division of the world into so-called nations.

In a world ruled by cities, we can hopefully talk more about urbanism, nature, sewage, garbage, transportation, education, health, prosperity, and cultural diversity—and less about war and peace…

It links across all or most design themes—not just addressing low or zero carbon, or water sensitive urban design, and stopping there, but making the point that the sustainable city has to be truly green, vegetated, biodiverse, and biophilic, too. Architects need ecologists to design good cities.

Es necesario contemplar las acciones concretas de la Ciudadanía respecto al cuestionamiento del papel de la naturaleza en la ciudad. Los gobiernos locales subestiman el poder de la acción ciudadana. Uno de los potenciales más poderosos es la capacidad que puede tener una complicidad público privada para una gestión efectiva de la biodiversidad en la transformación positiva de las ciudades. Este libro se logró gracias a la participación de más de 80 casos en diversos lugares de Colombia.
