Nearly a quarter of the world’s population lives in 17 countries facing extremely high water stress, close to “day zero” conditions when the taps run dry, according to a report released Tuesday.

The World Resources Institute’s Aqueduct Water Risk Atlas ranked water stress, drought risk and riverine flood risk using a peer-reviewed methodology.

“Agriculture, industry, and municipalities are drinking up 80 percent of available surface and groundwater in an average year” in the 17 worst affected countries, WRI said.
