Researchers mapped surface water quality under three different visions of future climate and socio-economic development. Water forecastTo investigate the future effects of similar trends, researchers modelled water quality in 20-year chunks from 2005 to 2100, using existing models of global water quality. They considered three future climate scenarios used by the Intergovernmental Panel on Climate Change, known as SSP1-RCP2.6, SSP5-RCP8.5 and SSP3-RCP7.0. In this model, organic water pollution in sub-Saharan Africa more than quadruples by 2100, leaving 1.5 billion people exposed to unsafe water. Deterioration in water quality in South Asia, the Middle East and North Africa also leads to increased pollution exposure in those regions.
