Water in Senegal
Water data, science and context for Senegal. Every figure carries its source and method, and Hydrionis states what it does not hold.

Where this number comes from
Source: World Bank — World Development Indicators, World Bank WDI indicator ER.H2O.INTR.K3. Licence: Open — attribution required (attribution required).
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. The World Bank publishes its datasets under CC BY 4.0, but relayed third-party material may carry the originator's own terms — verify with them before commercial reuse.

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. Originating body: FAO AQUASTAT and World Bank population estimates.

Method: Total annual freshwater withdrawn for agricultural, industrial and domestic use. Withdrawal is not consumption: much of what is withdrawn is returned to the source catchment.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

This is not a direct measurement. Output of a numerical or statistical model rather than a measurement.

Method: Population using an improved drinking water source that is accessible on premises, available when needed, and free from priority contamination — all three simultaneously. Modelled from household surveys and censuses, not counted. Originating body: WHO/UNICEF Joint Monitoring Programme.

How water is used
Sector shares are reported for varying reference years by country, and countries differ in whether thermoelectric cooling is counted as industrial withdrawal.
