Dryness in the summer rainfall region is expected to increase at 1.5℃ and higher levels of global warming  and together with higher temperatures will enhance evaporation from the region's mega-dams and reduce soil-moisture content . Increases in drought frequency and duration are projected over large parts of southern Africa at GWL 1.5℃  and unprecedented extreme droughts  emerge at GWL 2°℃ . Meteorological drought duration is projected to increase from approximately 2 months during 1950-2014 to approximately 4 months in the mid-to-late-21st century future under RCP8.5 .
