Short summary
The evolution of irrigation under climate change is analyzed between 1950 and 2100. Results indicate that the influence of irrigation on evapotranspiration in irrigated areas increases in the future (compared to an historical period). Also, the effect of irrigation on water resources is also higher in the future than in the historical period. Finally, we identify areas where future hydroclimate conditions can limit irrigation, or areas where irrigation can increase tensions around water use.
