Berlin's Sponge City Strategy: Building with Nature

TLDRBerlin is transforming itself into a Sponge City to deal with rainwater and heat by imitating nature. The strategy includes green roofs, urban wetlands, and road-side trenches that filter run-off and hold water, keeping the city cool. Despite challenges, Berlin is committed to managing stormwater on-site and adapting to climate change.
