The skin of the city shifts. Waves of residents come and go; meanings vanish. The longer I live here, the more I feel like I am a creature of many phantom limbs. Hungry, I walk to Jimmy’s hoping for fish and a chair to eat it in, but it is gone. In its place, a bodega expanded into a head...

July 24, 2016 What Do Rotterdammers Want in Green Infrastructure? We Asked Them
Marthe Derkzen, Amsterdam

Now that urban greening is increasingly seen as a climate adaptation strategy, the question is how to best provide the necessary green space. Where, at which scale, and what type of greenery? Which design is preferred? And how can municipalities increase public support for green adaptation measures? To find answers to these questions, we need to investigate local needs. This...

July 20, 2016 The Life Outside Gated Communities
Ragene Palma, Marikina City, Philippines

It’s a sunny morning and I leave the house, walking towards the gate of our subdivision. It’s just a few meters, downhill, around that pechay plantation, then uphill, typical of the sloping contour of Marikina Valley. In the two minutes and few meters, I see almost no one. Perhaps just Mr. Pechay, or so I call him, who’s busy tilling...

July 17, 2016 When Will We Start to Green the Roofs of Cities on a Massive Scale?
Andrew Clements, Corinth

The urban heat island is a well-known phenomenon that affects all cities around the world. It is the difference in temperature between a city and the surrounding suburban area. In countries such as Greece, the peak summertime temperature difference between a city such as Athens and its periphery can be as much as 10 degrees Centigrade. The causes of this...

July 12, 2016 The Forgotten Rurality: The Case for Participatory Management in Bogotá and its Surrounding Countryside
Diana Wiesner, Bogota

En español aquí. We often think of the city and the country as separate, and that development planning and urban sustainability and ends at the city boundary. But this isn’t true—in a planning and sustainability sense, the city and the surrounding rural areas are deeply linked. With this is mind, I would like to discuss a plan for the sustainable coexistence...

Urban schools—any public, private, or charter schools delivering formal primary or secondary education—are key institutions in the shaping of vibrant and sustainable cities. Imagining such cities depends on the assumptions and ideologies of those involved in the transformation of urban sites, and moving beyond perceiving urban schools as problematic institutions (Pink and Noblit, 2007). Globally, a steady process of urbanization...

December 12, 2012 The Invisible Urban Nature All Around Us: Beyond Green to Include the Built Infrastructure
Stephanie Pincetl,  Los Angeles

It is interesting that we think of nature in cities only as fauna and flora.  Mineral nature—the rocks and inert resources—is the stage on which living nature is set.  In cities, this means that the embedded nature all around us, that has been extracted from the Earth like the processed aggregate that we use to make concrete, or the oil...

In my first blog post for The Nature of Cities, I wrote about environmental justice as a bridge between traditional environmentalism and an increasingly urban global population. I suggested that we had work to do to makes environmental concerns salient to a new, ever-more urban generation. Since then, I have been working to test this hypothesis. To that end, I...
