Climate Change and Water Use Efficiency in Field Crops: Implications for Agricultural Adaptation in the U.S

No 358811, Miscellaneous Publications from United States Department of Agriculture, Economic Research Service

Abstract: Conclusions • Differential yield impacts across dryland and irrigated production: – Precipitation patterns, moisture stress, and irrigation requirements; – Temperature, biomass heat stress, and ET response; – CO2, water-use efficiency, and yield of C3 crops; • Irrigation demand declines beyond mid-century (relative to reference case), due in part to shifting water productivity in crop production. • Relative importance of climate impacts on irrigation varies regionally: – Surface-water shortages restrict irrigated area in PA, MN regions; – Relative profitability of irrigation the primary driver elsewhere. • Price and production impacts of surface-water supply reductions small relative to initial biophysical impacts of changing climate conditions.
