In an era rocked by climate change and other disruptions, our cities must be resilient to survive and thrive. But what does that mean, exactly? How can we address the problems facing cities today—poverty, job loss, crumbling infrastructure, pollution—while preparing for an uncertain tomorrow? To help answer those questions, Island Press launched the Urban Resilience Project, with support from The Kresge Foundation and the JPB Foundation. We began by reaching out to a diverse group of thinkers—activists, academics, architects and many others. And we asked them to help envision the sustainable, equitable, resilient cities of the future. In 2015, those thinkers produced a wide-ranging series of articles, blogs and op-eds, which are collected in Resilience Matters: Forging a Greener, Fairer Future for All.
