TS.C.4.3 Projected changes in the water cycle will impact various ecosystem services . By 2050, environmentally critical streamflow is projected to be affected in 42% to 79% of the world's watersheds, causing negative impacts on freshwater ecosystems . Increased wildfire, combined with soil erosion due to deforestation, could degrade water supplies . Projected climate-driven water cycle changes, including increases in evapotranspiration, altered spatial patterns and amount of precipitation, and associated changes in groundwater recharge, runoff and streamflow, will impact terrestrial, freshwater, estuarine and coastal ecosystems and the transport of materials through the biogeochemical cycles, impacting humans and societal well-being . In Africa, 55-68% of commercially harvested inland fish species are vulnerable to extinction under 2.5°C global warming by 2071-2100. In Central and South America, disruption in water flows will significantly degrade ecosystems such as high-elevation wetlands .
