Viola Has an Acorn in Her Pocket

Many voices. Greener cities. Better cities.

I live in Stockholm, Sweden. I enjoy talking walks in the autumn, inhaling the scent from degrading debris, kicking around dead leaves, and gazing at the vivid colors. This fall, my baby daughter has often followed me on my walks. Her name is Viola, and she is 4 years old.

Without critical discussion at Habitat III, could Smart City policies further disconnect children from experiences of nature?

Viola and I often walk to the grocery store to buy stuff missing for dinner. Farther on our path is a playground. Viola frequently stops and play for a while. Sometimes, we take a prolonged route through a forest grove on the way back to our apartment. It is not far away. In the forest, she often discovers tiny animals and plants, and asks me trillions of questions. I try to answer her every time. Sometimes, I do it in a mindful way, sharing her enthusiasm in the moment. But too often, I answer in an absentminded way, my mind unconsciously wandering to reflect on the experiences of today’s work and many other things.


Viola found an acorn on our path the other day: “What is this?” she asks. I point my finger towards an oak tree and answer her: “This is the seed of such a tree over there”. While gazing at the crown of the oak, she says: “It is amazing that a small acorn can transform into such a big tree”. Her comment surprises me and causes a warm sensation of affection in me as we share this moment of awe. But I just nod in a kind of stiff, Swedish way.

I tell her a story about the “forgetful Jay” that collect acorns for winter and then buries them into the ground. I tell her that the bird forgets most of them, and that this is how oak trees around here regenerate into new, big oak trees. I also tell her that an oak can live for a thousand years, and that there probably are many acorns in the ground around here that could grow into new oaks. She looks at the acorn for a short while, puts it in her pocket, and then we continue our walk back home. I ponder the experience we just had together. Someday, I will tell her that the Jay also need forests of pine for its needs, and about how different habitats are connected to form part of an ecological memory of the urban landscape we live in. I will teach her about the beauty of “slowness” in ecosystem dynamics.

As we continue our walk back home, my mind unconsciously wanders on. How interested will Viola actually be in learning about ecological memory, as narratives of what constitutes “a good life” increasingly might be shared on social media?

All this makes me think of Habitat III.

Habitat III

45,000 people supported by the UN met in Quito to discuss urban sustainability during the Habitat III conference. What’s new since the last conference, 20 years ago? The “Smart City” concept has entered the scene as a promising paradigm for a transition towards urban sustainability (HABITAT III, p. 10).

From a birds-eye perspective, the Smart City concept could perhaps simply be described by the words: rapid, digital, reflecting “the wired-in city”! It is the Internet of Things in the City! It is about increasing efficiency, which is important in terms of metabolic flows and regarding governance systems, as people attempt to cut costs and to decrease local and global pollutants.

There are naturally many positive aspects to wired-in infrastructures, some of which have been discussed before on The Nature of Cities. In 2012, Philip Silva wrote about cities as “cyborgs”, or hybrids between ecosystems and artificial systems, and that smart city solutions can and should work to clean and support local ecosystems. That blog made a lot of sense to me. But there are also critical voices of the Smart City movement. For instance, Sumetee Gajjar and Harini Nagendra raised questions regarding whether Smart City policies in India will include thinking about good governance and about local democracy, and whether such policies will blur the role that urban ecosystem services play in people’s well-being: wise words from India. Hollands (2008) questions whether the Smart City concept is for big business or for urban citizens.

Were such issues discussed in Quito?

Nowhere in the HABITAT III document is there any critical thinking addressing that the Internet of Things inevitably also means ever more screen time for people in their daily routines. It is noteworthy to mention here that increased screen time is discussed as a force driving kids to spend less time outdoors. In a recent paper, Soga et al., (2016) highlight examples where children in Japan spend much less time in natural environments compared to only 10 years ago, and that 12 percent of English kids have not visited a natural environment in the 12 months prior to the study.

Could Smart City policies unintentionally serve to further disconnect children from experiences of nature, perhaps inducing grand processes of social amnesia? Social-ecological memory (Barthel et al., 2010) involves the linking of social memory and ecological memory. Social memory refers to the accumulated collective experiences and knowledge of social groups or cultures, whereas ecological memory pertains to the remnants of biodiversity and spatial connectivity that persist in an area in the wake of a disturbance, such as a fire, flood, or construction of a road. As the ecosystem recovers from disturbance, ecological memory influences its reorganization. With a high degree of memory retention, the reorganized state of the system is more likely to resemble its former (i.e., pre-disturbance) state, but with low memory retention, the result of reorganization may be a fundamentally different, alternative stable state. Social-ecological memory is the collective memory of management practices that sustain ecological memory (Andersson & Barthel 2016).

How is social-ecological memory retained and eroded, and what might be the consequences of each? Integral to the production and persistence of memory are memory carriers—repositories and structures by which experiences and processes are transported in space and time (Ibid.).

Memory carriers may be ecological (e.g., gene pools, seed banks, and tree groves) or social (e.g., oral traditions, social norms, and media); improved understanding of how ecological and social memory carriers interact is hypothesized to be useful for fostering social-ecological memory and imagining new (or, perhaps, remembering old) avenues for place-based, sustainable living in the midst of rapidly unfolding global change. Alternatively, the loss of social-ecological memory may not only erode capacities for management of local ecosystems, but may also induce a broad societal shift in a psychological connection with nature.

In psychological literature, a connectedness with nature may be defined as an individual’s affective and experiential connection to nature (Mayer & Frantz, 2004, p. 504). As such, it can be viewed as a deep-seated attitude that forms an important part of predicting pro-environmental behavior (Ives et al., 2016). Of late, this perspective has also caught interest in sustainability science. An upcoming research group in Germany has identified a connectedness with nature as a “deep leverage point” for sustainability transformation (Abson et al., 2016).

Concerns are being raised about drivers that challenge people’s direct, sensory experience of nature and threaten to trigger baseline changes in people’s psychological connections with nature (Hartig and Kahn 2016). This is especially pressing from a children’s point of view. A deep-seated psychological connection with nature is most easily acquired during childhood (Giusti, et al., 2014; Cheng and Monroe, 2012; Chawla & Cushing, 2007) and persists unchanged through adulthood (Kaiser et al., 2014). To quote Miller (2005), “[if] people no longer value nature or see it as relevant to their lives, will they be willing to invest in its protection?”

Nearly home now…

We continue our walk home, dusk approaching, and the northern sky turning pink, my thoughts wandering mindlessly…Will our walks make any difference? Will they help instill Viola with a sense of care for nature? How will Smart City policies interfere with Viola’s experiences in the near future?…How is it possible that the voice of Nick Drake holds such sensitivity and wisdom despite that he passed away in his twenties? Probably I am just getting old…

Viola runs ahead of me towards our front door. We are home. Viola has an acorn in her pocket.

….“I never felt magic crazy as this…”

Stephan Barthel is at the Stockholm Resilience Centre and the University of Gävle, where he researches environmental issues in metropolitan landscapes, with focus on social features that have a bearing on the capacity to manage and design for urban biodiversity and ecosystem services. His publications are on historical land use and contemporary management, design and planning of green infrastructures in Stockholm and Berlin. Comparative studies on common property rights to urban nature are under construction including studies in Cape Town and the Randstand region in the Netherlands. He also works with archeologists and historians where we use a resilience lens on urban environmental histories on Constantinople and Cities of The Maya. Concepts he is part of developing with colleagues are: Social-Ecological Memory, Innovative Memory, Urban Anthropocene, Urban Green Commons, and Pockets of Social-Ecological Memory. He uses research methods from physical sciences as well as social sciences, combining qualitative and quantitative approaches, and integrates systems thinking with social theories and the humanities in an attempts to better understand emergent properties of complex social-ecological systems. Of late he is also interested in the relationship between the urban and the rural, focusing on food security and how urbanization interacts with the capacity to grow food. When discovering the importance of food and relations between the urban-rural it seems that the resilience function of interlinked bio-cultural diversity in landscapes of food production must be more fully understood, an issue he will try research with colleagues during 2013. Since 2012 he has coordinated the ’Urban Theme’ at SRC with Dr. Colding and Dr. Gren.

  1. I agree. from a psycological perpsective any such contact as feeding birds-is of crucial importance for instilling a connctedness with nature in kids. Good idea to put of signs…

  2. My grandchildren loved going to urban parks to feed ducks and migratory birds. Now the signs forbid this, in the supposed interest of the birds’ welfare, they have lost interest in going. Why not just signs up advising to avoid white bread, or selling small bags of suitable seeds?
