Too much, too little. With the impacts of climate change, water from being a precious resource can easily turn into an environmental disaster.
This is the case of the Chinese city of Zhengzhou, in the Henan region, which last year faced the heaviest rain ever and devastating floods that killed at least 300 people and displaced 1.24 million residents. It is evident that a rethinking of how we inhabit the planet is urgently needed and overturning how, for centuries, we have designed infrastructures in order to dominate and control nature, instead of creating a circular and virtuous relationship.
Master in doing this kind of operations is Kongjian Yu who, with his design studio Turenscape, carries out experimentation and evocative and important projects to set new design models. The basic idea of him? That we have the responsibility to make nature our teacher, because she has a lot to teach us.
In particular, the Sponge Cities approach teaches us that innovation can be based on local knowledge and territory, that indispensable piece in the motto 'think global, act locally'.
