This map shows the average exposure of water users in each country to baseline water stress, the ratio of total withdrawals to total renewable supply in a given area. A higher percentage means more water users are competing for limited water supplies.
Our analysis finds that 37 countries currently face "extremely high" levels of water stress, meaning that more than 80 percent of the water available to agricultural, domestic, and industrial users is withdrawn annually.
EDITOR'S NOTE: The working paper on this page has been updated. The previous version listed Northern Cyprus as a country. It has been removed from this version, as it is an internationally disputed territory. The description has been revised accordingly.
