Climate change impacts will increase the number of people at risk of hunger, in 2050 ranging from 8 million people under SSP1 to 80 million people under SSP3 scenarios , compared with a world with no climate change . Estimates also vary depending on the adaptation and mitigation assumptions . Geographically, nearly 80% of the population at risk of hunger are projected to reside in Africa and Asia . Projections of risk of hunger beyond 2050 are limited, but it will grow from the mid-century towards the end of the century, with more people at risk under RCP8.5 compared with RCP4.5 . Regional disparity is projected to increase, particularly under a high-emission scenario.
