As climate change intensifies and cities grapple with expansion pressures, natural habitats and biodiversity are under threat. Prioritizing urban rewilding offers a way to balance urban development with supporting biodiversity–while at the same time, tackling the climate crisis. 

Urban rewilding is the process of restoring natural habitats and their processes within urban spaces and working toward a state of human-nature symbiosis. Even within built-up areas, thoughtful approaches to urban rewilding can support healthy ecosystems and contribute to numerous climate action strategies, like heat mitigation and air quality. This report from C40 Cities and Arup offers guiding principles for urban rewilding, typologies of projects that can be implemented, and over 20 case studies of successful initiatives from around the world.
