Technical Description

The Global Water Stress Projected Risk products capture the projected risk of water stress and water depletion across the globe using a well established hydrology and water resources model. These risk maps reflect the future risk of water stress and depletion in global land areas for 2030, 2050, and 2080 for Shared Socioeconomic Pathway scenario SSP3-7.0.

This dataset contains the following fields:

  • water_stress_risk_score: The water stress risk score measures the projected ratio of total water demand to available renewable surface and groundwater supplies for each pixel location. Water demand includes domestic, industrial, irrigation, and livestock consumptive and nonconsumptive uses. Available renewable water supplies include the impact of upstream consumptive water users and large dams on downstream water availability. Higher values indicate more competition among users. Values range from 0-5 representing low (0-1), low-medium (1-2), medium high (2-3), high (3-4), and extremely high (4-5) water stress risk.
  • water_depletion_risk_score: The water depletion risk score measures the projected ratio of total water consumption to available blue water for each pixel location. Total water consumption includes domestic, industrial, irrigation, and livestock consumptive uses. Available renewable water supplies include the impact of upstream consumptive water users and large dams on downstream water availability. Higher values indicate larger impact on the local water supply and decreased water availability for downstream users. Values range from 0-5 representing low (0-1), low-medium (1-2), medium high (2-3), high (3-4), and extremely high (4-5) water depletion risk.
