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

Where this number comes from
Source: World Bank — World Development Indicators, World Bank WDI indicator ER.H2O.INTR.PC. Licence: Open — attribution required (attribution required).
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. 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.

Where this number comes from
This is not a direct measurement. Output of a numerical or statistical model rather than a measurement.
Source: World Bank — World Development Indicators, World Bank WDI indicator SH.H2O.SMDW.ZS. Licence: Open — attribution required (attribution required).
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. 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.

In regional context
A national per-capita average conceals seasonal and regional distribution entirely.
