SUMMARY：

Climate change is felt most profoundly through water impacts, whether too much or too little. And while more and more people are living in cities, often located on rivers or on the coast, with longer periods of drought, massive subsidence due to groundwater extraction and heavy rains coupled with coastal geography， these cities become increasingly vulnerable to the impacts of climate change. Traditional projects and interventions cannot keep pace with the impact of climate change on global water supplies. A new approach is needed, by design.
