World's Groundwater Supplies Draining Fast, NASA Study Says

Using a new approach, scientists reveal earth's fast-draining aquifers.

"Most of those aquifers are the ones that support the world's major food production," Jay Famiglietti, a senior water scientist at NASA’s Jet Propulsion Laboratory and co-author of the ground water study, told ABC News.

“Humanity has done a terrible job with groundwater stewardship,” Famiglietti said.

“Because of climate change, we will be seeing even less replenishment of those aquifers,” Famiglietti said.

“It really paints a compelling picture for the problems of the future,” Famiglietti said.
