Constraints and potentials of future irrigation water availability on agricultural production under climate change pub iis_cli iis_fag iis_mod iis_wat prog_esm prog_wat Adaptation; Agriculture; Hydrology; Uncertainty We compare ensembles of water supply and demand projections from 10 global hydrological models and six global gridded crop models. These are produced as part of the Inter-Sectoral Impacts Model Intercomparison Project, with coordination from the Agricultural Model Intercomparison and Improvement Project, and driven by outputs of general circulation models run under representative concentration pathway 8.5 as part of the Fifth Coupled Model Intercomparison Project. Models project that direct climate impacts to maize, soybean, wheat, and rice involve losses of 400-1,400 Pcal (8-24% of present-day total) when CO2 fertilization effects are accounted for or 1,400-2,600 Pcal (24-43%) otherwise. Freshwater limitations in some irrigated regions (western United States; China; and West, South, and Central Asia) could necessitate the reversion of 20-60 Mha of cropland from irrigated to rainfed management by end-of-century, and a further loss of 600-2,900 Pcal of food production. In other regions (northern/eastern United States, parts of South America, much of Europe, and South East Asia) surplus water supply could in principle support a net increase in irrigation, although substantial investments in irrigation infrastructure would be required. 2014-03 published National Academy of Sciences 10.1073/pnas.1222474110 XJ-14-070 PNAS; 111(9):3239-3244 (4 March 2014) (Published online 16 December 2013) [doi:10.1073/pnas.1222474110] Special Feature 2601 1855 92 151 1542 268 public Proceedings of the National Academy of Sciences 111 9 3239-3244 TRUE 1091-6490 Water futures and solutions initiative (WFaS) FALSE info:eu-repo/semantics/article
