In nearly a third of the world's largest cities, water demand may exceed surface water availability by 2050, based on RCP6.0 projections and the WaterGAP3 modelling framework . Under all SSPs, the global volume of domestic water withdrawal is projected to reach 700-1500 km3 yr-1 by 2050, indicating an increase of 50 to 250%, compared to the 2010 water use intensity  . Increasing water demand by cities is already spurring competition between cities and agricultural users for water, which is expected to continue  . By 2030, South and Southeast Asia are expected to have almost three quarters of the urban land under high-frequency flood risk . South Asia, South America and mid-latitudinal Africa are projected have the largest urban extents exposed to floods and droughts . An analysis of 571 European cities from the Urban Audit database
