Sponge cities use natural features to slow down, soak up and reuse flood water.
Yu Kongjian nearly drowned as a boy when his village flooded, but it inspired him to come up with the sponge city concept. It鈥檚 now being rolled out across China.

It comes as cities around the world are struggling to cope with more extreme weather caused by climate change.
