Who Takes Care of New York?
Lindsay Campbell,  New York

Civic leaders and community members regularly put time and energy into caring and advocating for the environment. We call these acts of care stewardship. Beyond improving green and blue spaces, stewardship can also lead to other types of civic action. Local stewardship groups can strengthen social trust within a neighborhood. People who come together around the shared love of a...


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

A Fractal Solution to Regional Complexity and Governance
Mathieu Hélie, Montréal

Could we construct a new image of what the political boundaries of an urban landscape could take shape as? Instead of the hierarchical approach that is commonplace, with cities governed by layers of neighborhood, urban, regional, and state-provincial levels through different electoral or appointed bodies, I propose to approach the problem geometrically, by using the principles of scaling and iteration...

Peleg Kremer, Princeton
Annegret Haase, Leipzig
Dagmar Haase, Berlin

Equity and Sustainability: a history of ideological convergence vs. practiced indifference The idea that equity is an important and indispensable part of sustainable development has been there from the early days. The intellectual basic for and actions taken towards sustainability are thought to be fundamentally fair and just—a world in which all have access and means to the resources needed...

And, Now What? Exploring what happens after a 16,000-kilometer walk across two continents
Jennifer Baljko, Barcelona

Those last few days in June, we could see Barcelona’s shape in the distance. The three chimneys from the old power plant. The slanted roof of the Forum. The towers from the Olympic village. The long stretch of beach reaching to the glass sail that is the W hotel. The blue of the Mediterranean that always stirs a “Come to...

Protecting More with Less: More Nature in Cities with the Science of Strategic Conservation
Will Allen,  Chapel Hill

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...


Unintended Consequences: When Environmental “Goods” Turn Bad
Francois Mancebo,  Paris

After a hectic start to 2015, I finally managed to slow down the pace. A few days ago, I attempted to catch up on some overdue readings—my way to keep in the loop. Among the many documents piling up on my computer desktop was this short podcast from TNOC: “Closing the Sustainability and Equity Gap: What does it mean to...


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...


A New Reconnection Agenda for People and Nature
