Changes in climate, demography and lifestyles increase imbalances between water availability and water needs for agriculture, energy, manufacturing, livestock, households and ecosystems. Resulting water scarcity increases competition for water resources between different sectors and nations.
Assessing future water-scarcity impacts worldwide requires quantifying the consequences of such trends. An integrated water assessment framework will be developed. This framework consists of models for hydrology, crop cultivation, electricity production, sectoral water demands and allocation. This framework will produce water scarcity maps and identify trade-offs and synergies within the water-food-energy nexus for different scenarios up to 2050, which help to develop better water management strategies.
