Method: Renewable internal freshwater resources: the long-term average annual flow of rivers and recharge of groundwater generated from precipitation within the country. Internal resources exclude inflow from upstream countries, so this is the measure of self-sufficiency rather than of total availability. Originating body: FAO AQUASTAT.

Method: Renewable internal freshwater resources divided by population. Because the population denominator updates annually while the resource figure is a long-term hydrological average, movement in this series is largely population change rather than hydrological change.

Method: Total annual freshwater withdrawn for agricultural, industrial and domestic use. Withdrawal is not consumption: much of what is withdrawn is returned to the source catchment.

Method: Industrial withdrawal as a percentage of total freshwater withdrawal. Countries differ in whether thermoelectric cooling is counted here, and where it is the share reflects cooling arrangements rather than manufacturing intensity. Originating body: FAO AQUASTAT.
