Singing in the Noise
Luis Sandoval,  San José, Costa Rica

Urbanization not only changes the landscape structure due to land cover change, fragmentation of natural habitats, and creation of artificial habitats, it also changes the physical patterns of the environment: temperature, wind currents, rain patterns, light levels, or noise levels. For example, urbanization increases average temperature by between 3°C and 5°C, in comparison to nearby rural or natural areas, because...

Thinking About the Concept of “Cultural Nature” while Walking the Gardens of Méréville
Louise Lezy-Bruno, Paris

The first time I visited the Méréville Estate and its Anglo-Chinese garden, created south of Paris at the end of the 18th century, I was struck by the interlinking of nature and culture in this amazing place. This National Heritage Site is the work of the Marquis de Laborde, who acquired the estate in 1784 and involved the greatest artists...

The Sustainability Challenge of Feeding Cities
Graciela Arosemena, Panama City

The food system is not as evident as other aspects of urban development. However, it involves many aspects of cities, such as mobility and transportation, commerce, land use, waste management, and, of course, food security. The food system refers to processes that begin with agricultural production and continues with the processing, packaging and transport that is the result of food...

Ecologies of Elsewhere: Giving Urban Weeds a “Third Glance”
Daniel Phillips, Bangalore

Volunteers. Exotics. Aliens. Weeds. Whatever happens to be your preferred nomenclature when describing the existence and behavior of spontaneous vegetation, it’s clear that many biases abound. We pluck, poison and mulch our landscapes to keep these decidedly untidy forces at bay. Yet have we also effectively mulched our mindsets?  Have we blunted our ability to see these ubiquitous features of our...

Re-culturing an Urban Collective Ethos of Sustainability
Harini Nagendra, Bangalore

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,...

Making Connections and Feeding Relationships: Reflections from a Biocultural Axiom of Aloha
Heather McMillen,  Honolulu & New York City

What if urban resource management and conservation reflected not just the politics and science of the day, but were rooted in creation stories, place-name stories, and personal stories about the relationships people have with place? This kind of thinking is at the heart of traditional ways of stewarding the environment in many remote and rural place-based communities around the globe,...

Intensiveness and Extensiveness in Our Urban Landscape
Andrew Rudd,  New York City

Much of urban history has emphasized density and centrality in city form. Though some environmentalists question the sustainability of such intensive land use, recent studies have shown that urban density correlates positively with resource efficiency and reduced emissions. At the same time, innovations in transport technology have historically allowed cities to extend their spatial edges. This tendency towards urban sprawl...
