For fossil aquifers?such as the vast U.S. Ogallala aquifer, the deep aquifer under the North China Plain, or the Saudi aquifer?depletion brings pumping to an end."

that's a good article, thanks, I wasn't aware that all of the world's vital agricultural regions were being impacted like this also.
Also, I think groundwater is another term for fossil water. The 63 trillion gallons gone from this region since 2013 are from the acquifer of this region, but i can't recall the name of it.
