Why some regions are winning the fight against groundwater depletion

For half the world’s population, the water in their drinking glasses comes from below them. Groundwater also supplies 40% of global irrigation projects.

Declining water tables leave entire regions vulnerable to drought, land subsidence or seawater intrusion while damaging ecosystems and reducing water access. Properly securing this resource is a matter of social, humanitarian and environmental security.
