Sponge Cities: Integrating Green and Gray Infrastructure to Build Climate Change Resilience in the People’s Republic of China
Publication | November 2022
This brief explains how the People’s Republic of China is developing so-called sponge cities that use nature-based solutions to help reduce disaster risks posed by urbanization and climate change.
Detailing how sponge cities absorb and then slowly release rainwater, it analyzes lessons from the PRC’s experience so far and explores how they can be applied for even greater impact in the PRC and more broadly in Asia and the Pacific. It underscores the need for governments to prioritize nature-based adaptation approaches integrated with risk-informed planning to retrofit cities and systematically plan new urban areas to reduce disaster risk and increase resilience.
