TS.C.4.6 Projected water cycle changes will impact agriculture, energy production and urban water uses . Agricultural water use will increase globally as a consequence of population increase and dietary changes, as well as increased water requirements due to climate change . Groundwater recharge in some semiarid regions are projected to increase, but worldwide depletion of non-renewable groundwater storage will continue due to increased groundwater demand . Increased floods and droughts, together with heat stress, will have an adverse impact on food availability and prices, resulting in increased undernourishment in South and Southeast Asia . In the Mediterranean and parts of Europe, potential reductions of hydropower of up to 40% are projected under 3°C warming, while declines below 10% and 5% are projected under 2ºC and 1.5ºC warming levels respectively. An additional 350 and 410 million people living in urban areas will be exposed to water scarcity from severe droughts at 1.5℃ and 2℃ respectively.
