Fig. 3: Comparison between our predictions and the GMs estimations.

The black dots and the error bars show the median, the minimum and the maximum irrigation water withdrawal values predicted from the irrigated areas reported by the FAO-GMIA96 (Methods). The coloured dots show the irrigation water withdrawal estimates outputted by the GMs (DBHM, H08, LPJmL, MPI-HM, PCR-GLOBWB, VIC, CLM45, WaterGap) or reported by the FAO-based datasets (Aquastat, Liu et al.19). a Africa. b Americas.
