Despite increased temperatures and much regional variation in production response, U.S. irrigated fieldcrop acreage and water used for irrigation are projected to decline with long-term climate change. Driving the decline in water use are changes in crop growth due to temperature stress, changes in growing-season precipitation, and shifts in surface-water supply availability.
