Three climate change scenarios were considered: low emissions (RCP 2.6), medium emissions (RCP 4.5) and high emissions (RCP 8.5). Each scenario was projected using twelve different climate models, and the median result was taken as the value for the respective drought and flood indicators. Scenarios of no adaptation as well as low and high adaptation were taken into consideration. The greatest vulnerabilities are seen in areas of sub-Saharan Africa and South and South East Asia, where millions of people are likely to face greater risk of food insecurity as a result of climate change by the 2050s.
