Sponge city urban planning implementation
Overview
The ‘sponge city’ urban planning model is being utilized to address extreme weather fluctuations, such as heavy storms and severe droughts, in European and Chinese cities.
Developed in China by landscape architect Kongjian Yu, the model involves retrofitting urban areas with permeable surfaces, green spaces, wetlands, and ponds. These features aim to absorb rainwater to reduce pressure on drainage systems while providing water for irrigation and groundwater recharge during dry periods. The model also offers secondary benefits, including cooling streets during heatwaves and providing moisture to protect against wildfires.
In France, municipalities are adopting these concepts to combat flooding and heatwaves. In Illkirch-Graffenstaden, the local government has launched a ‘Green Book’ initiative to prepare for climate impacts by cooling public buildings, increasing tree canopy coverage, and protecting vulnerable populations. Meanwhile, China has set a goal to have 80 per cent of its built-up urban areas functioning as sponge cities by 2030.
