Cities worldwide are increasingly vulnerable to extreme weather events. Droughts are lasting longer, heatwaves are becoming more intense, and storms are bringing rainfall that existing infrastructure can no longer handle. Sponge cities offer a nature-based solution to these challenges by restoring natural water cycles. Through innovative urban design, sponge cities incorporate green infrastructure like green roofs, permeable pavements, and swales to absorb and manage rainfall, mitigate the urban heat island effect, and provide resilience against droughts. Originally developed in China, the sponge city concept has been adopted globally. As climate change continues to intensify, sponge cities provide an affordable, scalable solution for creating sustainable, climate-resilient urban environments.
