These crops account for 61% of the African crop production (kcal capita-1 day-1) and 62% of African harvested area (ha). Future scenarios of crop water footprintTo compute the water footprint of every crop for each scenario, the high-resolution crop water footprint model WaterCROP24 was used. Accordingly, we have adapted our methodology to include the non-linear linkage between crop yield and crop water use to obtain water footprint results mirroring the GAEZ attainable crop yields. Regarding climatic and yield data estimates, we use the ensemble obtained as the average of all the GCMs realizations available. 5, according to current extensification trends, while assuming the same total crop production as the hard-intensification scenario is achieved.
