The Ogallala aquifer
Farmers in Kansas and other states that sit atop the Ogallala aquifer--the largest freshwater aquifer in North America--are pumping out water for crop irrigation far faster than natural seepage of rainwater can replenish the aquifer. Scientist David Hyndman from Michigan State University is helping develop a plan to better manage this vital resource for sustainable farming.
