The groundwater that supplies farms, homes, industries and cities is being depleted across the world. And in many cases, it’s happening at rates faster than in the past 40 years. That’s according to researchers whose work was published Wednesday in the journal Nature. Groundwater is one of the largest freshwater sources anywhere in the world, making the depletion of aquifers a significant concern.

They analyzed groundwater data from 170,000 wells from nearly 1,700 aquifers across more than 40 countries.
