Sustainability: Water - 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 it. Scientist David Hyndman from Michigan State University is helping develop a plan to better manage this vital resource for sustainable farming. "Sustainability: Water" is produced in partnership with the National Science Foundation.
