'Resiliency has risen to one of the top subjects that we talk about now in the sustainability world.'

By Maria Gallucci

American cities on the frontline of climate action are quietly but dramatically shifting their approach—from primarily trying to limit global warming to coping with its impacts. They're building forested buffers to shelter homes from wildfires, considering concrete sea walls to restrain ocean waters and developing software to conserve water during drought.

Now, a new global initiative aims to make nearly a dozen of those cities into models that can spur urban resiliency around the world.

The Rockefeller Foundation, which launched its 100 Resilient Cities Network earlier this month, said that cities' ability to "withstand and bounce back" from climate and other disasters is crucial as more people move to metropolitan areas and as urban economies become inextricably linked.

"What happens in one part of the world can shake the stability of another," said spokeswoman Carey Meyers.
