Fig. 2: Spatial pattern of irrigation expansion and simulated irrigation water withdrawal in different periods.
From: Impacts of irrigation expansion on moist-heat stress based on IRRMIP results
a Increase in irrigated fraction between 1901 and 2014, and the IPCC reference regions71 used in the analysis. b Irrigated fraction in the year 2014 (Irrigated fraction in the year 1901, 1941, and 1981 could be found in Fig. S3a–c). The grid resolution is the simulation resolution of CESM2, CESM2_gw, and NorESM (0.9° × 1.25°). c, d Multi-model mean simulated annual irrigation water withdrawal (IWW) with transient irrigation extent (tranirr) during the first 30 years (1901–1930: (c) and the last 30 years (1985–2014: (d). The figure showing results from all individual models can be found in Fig. S15. Multi-model mean simulated annual IWW with fixed irrigation extent (1901irr) during the two periods can be found in Fig. S3e, f.
