Abstract: | This study evaluates the theoretical impact of climate change on yields and water use of two crops with different responses
to increased CO2 and which represent contrasting agricultural systems in Spain. In all cases the simulated effects of a CO2-induced climate change depended on the counteracting effects between higher daily ET rates, shortening of crop growth duration
and changes in precipitation patterns as well as the simulated effects of CO2 on the water use efficiency of the crops. For summer irrigated crops such as maize, the yield reductions and the exacerbated
problems of irrigation water availability simulated with climate change may force the crop out of production in some regions.
For winter dryland crops such as wheat, productivity increased significantly in some regions, suggesting a northward shift
of area suitable for wheat production in future climates. The study considered strategies for improving the efficiency of
water use based on the optimization of crop management decisions in a CO2-driven warmer climate.
