In east and southern Africa and the Sahel, malaria vector hotspots and prevalence are projected to increase under RCP4.5 and RCP8.5 by 2030   , becoming more pronounced later in the century  . Under RCP4.5, 50.6-62.1 million people in east and southern Africa will be at risk of malaria by the 2030s , and 196-198 million by the 2080s  . Northern Angola, southern DRC, western Tanzania and central Uganda are predicted to be worst impacted in 2030, extending to western Angola, upper Zambezi River basin, northeastern Zambia and the east African Highlands by 2080 . Under rising temperatures, by the 2050s, the greatest shifts in suitability for malaria transmission will be seen in east, southern and central Africa  .
