Sponge City: Making Berlin Cooler

The video discusses the challenges urban spaces face with heat and water management, highlighting Berlin's innovative 'sponge city' strategy. This approach aims to mimic natural water cycles by using green roofs and urban wetlands to manage rainwater and heat. Romsburg in East Berlin serves as a practical example of this concept. Despite progress, challenges remain, as seen during the heavy rains of 2017. The city council now mandates stormwater management in new developments, adapting urban environments to work with nature amid climate change.
