Extended Data Fig. 1: Area equipped for irrigation and irrigation water withdrawal in four climate reference regions.
From: Irrigation-induced land water depletion aggravated by climate change
Varying evolution in area equipped for irrigation and irrigation water withdrawal in four regions. Area equipped for irrigation (AEI) in the region South Asia (a), Mediterranean (b), Central North America (c), and West Central Asia (d). Annual simulated irrigation water withdrawal (IWW) from seven Earth System Models in four regions of the experiment with (tranirr) and without irrigation expansion (1901irr) (e-h). Solid lines are the mean value of seven Earth System Models, and ranges indicate the maximum and minimum values. Curves indicating irrigation water withdrawal were smoothed using Savitzky-Golay filtering (order=2, window = 19)73.
