Water Safe Cities: how flooding and drought will impact C40 cities by 2050

The following report explores how C40 cities are set to see an increase in the different types of flooding that occur in urban areas and what this means for people and public funds, and how cities are working hard to keep their populations water safe. Cities around the world are no strangers to riverine flooding.  Venice ,  São Paulo ,  Sydney  and  Kuala Lumpur  are just a few examples of cities that have experienced inundation that has brought them to a standstill over the past three years.

The five C40 cities with the largest amounts of riverine flooding are in South and South East Asia, but nearly all C40 cities are set to see a dramatic increase between now and 2050. Cities in Latin America see some of the most dramatic increases by 2050. What’s more, the impact on populations in Global South C40 cities will be 10 times that on populations in Global North cities.
