In response to climate change, Berlin has adopted the ‘sponge city’ approach in new districts to manage rainwater effectively. The initiative aims to absorb, retain, and reuse rainwater to prevent flooding and drought. Local authorities have designed eco-friendly neighborhoods, such as the innovative Grünau district, where rainwater is captured and utilized without entering the sewage system. This sustainable urban design has proven effective, as these neighborhoods have not experienced flooding. The project emphasizes the importance of green spaces and artificial basins to maintain a microclimate in urban settings.
