Our fractured metropolitan regions are the big problem in creating sustainable solutions for climate challenges. High-towered, dense city living is only a small part of the solution, which is to develop “ecological urbanisms.”

Australia circa 2050, population 35 million, climate change induced rising sea levels have flooded the Gold Coast resort region, apartment blocks are now used to grow food and people commute in monorail pods above the sea.

Merging complex systems science and ecology, resilience scientists have broken new ground on understanding—and preserving—natural ecosystems. Now, as more and more people move into urban hubs, they are bringing this novel science to the city.

The world is going through a massive urbanization, overturning the traditional demographic order and challenging two millennia of literary and cultural concepts of the urban. In this last post, I want to return to the ecological impacts of that urbanization…and what conservationists can do to mitigate it.

The Hatoyama government’s ambitious carbon reduction goals position Japan for leadership in the postindustrial global economy. Less discussed is Tokyo’s remarkable energy efficiency, urban ecology innovations, and its potential for playing a leading role in the next decade’s biggest environmental challenge: creating sustainable cities with human and environmental benefits.

CityLAB, an urban design think tank at the University of California, Los Angeles, took on the challenge of design-inspired infrastructure earlier this year with the creation of WPA 2.0: Working Public Architecture. [3] Inspired by the Works Projects Administration of the 1930s — the largest and most effective of the agencies created by the Roosevelt administration — WPA 2.0 has so far included a global design competition, a multidisciplinary symposium and (coming in February) a web exhibition.

A finalist in the WPA 2.0 competition sponsored by UCLA Citylab, Nicholas de Monchaux and collaborators have provided a case study showing the impacts of the “spaces between places,” spaces owned by the city but unused and still maintained. Monchaux’s group, using geospatial analysis identify thousands of these publicly owned, abandoned spaces and quantify their transition into a network of urban greens.

It’s clear in retrospect that the fracture-critical structures of the 1950s and ’60s reflected the larger culture — this was when John Kenneth Galbraith famously critiqued the United States as a nation of private affluence and public squalor. In an era when America could have afforded the best infrastructure in the world, we began instead to channel wealth into private hands and to impoverish the public realm.

By requiring car drivers to pay a fee to drive in a city at peak hours, congestion pricing reduces traffic and raises money that can be used to support public transit—both worthy goals.
Yet congestion pricing has dubious environmental value. Traffic jams, if they’re managed well, can actually be good for the environment. They maintain a level of frustration that turns drivers into subway riders or pedestrians.
