Fig. 3: The impact of climate change on soil moisture availability and the implication for food security.

a Average water stress condition in 2010 expressed by the water stress coefficient (ks); (b) variation of the average water stress coefficient by 2040, RCP6.0 compared to 2010; (c) country-average variation of water stress coefficient in 2040, RCP6.0, plotted against the prevalence of moderate or severe food insecurity in the population in 201939 (refer to Supplementary Table 1 for the complete country name associated to each code). The size of the bubble is proportional to the national rainfed harvested area and the color indicates the region.
