Worldwide, cities are challenged by water excess that can cause widespread floods. Fast-growing cities, of which many are in low lying deltas, are under pressure to accommodate changing societies and to protect their inhabitants, especially those in the global South. Moreover, urban drainage infrastructures increasingly have difficulties coping with the imminent higher rain intensities caused by climate change. So how can you make a city more resilient to flood problems, providing stakeholders with a secure environment to build up their livelihoods and sustain socio-economic growth? That’s what the case study Climate Resilient Cities is about.
