Water demand for irrigated agriculture is calculated in LPJmL, based on requirements for evapotranspiration for the crop types grown on irrigated land. For other sectors (households, manufacturing, electricity and livestock), water demand is calculated based on population, economic growth, industrial value added, and electricity production as projected with IMAGE-TIMER. | Water demand for irrigated agriculture is calculated in LPJmL, based on requirements for evapotranspiration for the crop types grown on irrigated land.

Example: Projected increases in agriculture, energy and industry production, and population lead to increased water demand. Climate change also impacts the water cycle. While overall climate change is projected to lead to more precipitation, geographical patterns show changes to drier and to wetter local climates. In addition, increasing temperature leads to more evapotranspiration. As a result, the water balance improves in some regions and deteriorates in other regions, and the pattern of these changes is very uncertain. In combination with increased demand, the areas confronted with crop production losses are projected to increase significantly as shown in | Example: Projected increases in agriculture, energy and industry production, and population lead to increased water demand.
