In most regions of China, precipitation and annual mean temperature would increase over time, and this trend was more obvious in the RCP 8.5 scenario.
The ETc and yield of maize in the northern areas would be generally higher than those in the southern areas. The increase in temperature and CO2 concentration would contribute to a higher maize yield per unit area.
Deficit irrigation could result in high water use efficiency and increase the maize yield in Northwest China while more irrigation would greatly benefit the maize yield in arid and semi-arid areas.
Irrigation could alleviate the adverse effects of climate change on the water footprint of maize in arid regions, which also demonstrated regional differences.
