How "sponge cities" can prevent floods and droughts
As cities experience the effects of climate change, new designs are emerging to mitigate risks.“Sponge cities” can absorb, filter and store surface water, whilst also sanitising it. It's a sustainable water management solution for urban development, so the built environment can adapt to droughts and floods.Instead of impermeable asphalt roads and concrete playgrounds - that act as heat islands - sponge cities incorporate natural and green infrastructure that permits water to filter underground supported by surface flood plains built of earth, gravel, sand and grass. It's a protective above and below ground solution harnessing resources based on nature.
