Water Yield: The map shows the water yield obtained from the water accounting analysis.
The water yield is defined as water that is available after meeting landscape water
requirement (landscape ET).
This is the amount of water that
can be exploitable for human
needs. The map shows water
yield for administrative regions
within the basin. Some regions
shows negative values (shades
of red), which indicate that at
annual time scales there is not
water available. Other regions
show positive values (shades of
blue) which indicate that at
annual time scale, water
availability for human needs is
not a problem. Such information is important to understand spatial variability of water
availability within the basin. The blue areas are also called water towers of the basin are the
regions that provide most water to the river and where future activities such as irrigation
development or canals for diverting water can be constructed
3.2 Water Availability

Information on water availability in a river basin is crucial for understanding various aspects
of human, environmental, and economic well-being. Through this dashboard, water
availability in a river basin is summarized using indicators of water availability for a) humans
b) environment c) agriculture and d) other uses.

Water Availability Per Capita (m3/per capita): Water availability per capita refers to the
amount of freshwater resources available for each person in a specific region or country. It is
typically measured in cubic meters (m³) per person per year and is an important indicator of
a region's or country's ability to meet the water needs of its population while also supporting
economic and environmental demands. Calculating water availability per capita involves
dividing the total annual freshwater resources of a region or country by its population. Within
water accounting, we derive water availability per capita as

Water Availability Per Capita =
