Water availability

Water availability in a grid cell is the sum of locally generated blue water and the blue water flowing in from upstream grid cells, which intrinsically accounts for upstream water use, minus an environmental flow requirement which amounts to 80% of the naturalized streamflow in the grid cell.

Water scarcity

Water scarcity in a grid cell is the ratio of the local consumptive water use to the total water availability in the grid cell.

Water stress

Water stress in a grid cell is the ratio of the local water withdrawals to the total water availability in the grid cell.
