Groundwater pumping is drying up the Great Plains

❝ Farmers in the Great Plains of Nebraska, Colorado, Kansas and the panhandle of Texas produce about one-sixth of the world’s grain, and water for these crops comes from the High Plains Aquifer — often known as the Ogallala Aquifer — the single greatest source of groundwater in North America. A team of researchers, including Colorado State University and , a CSU alumnus and an assistant professor at the University of Alaska Fairbanks, have discovered that has led to long segments of rivers drying up and the collapse of large-stream fishes.

If pumping practices are not modified, scientists warn that these habitats will continue to shrink, and the fish populations along with them.

❝ The research team combined modeling from the past and future to assess changes in Great Plains streams and their fish populations associated with groundwater pumping from the High Plains Aquifer. The findings have implications for watersheds around the world, because irrigation accounts for 90 percent of human water use globally, and local and regional aquifers are drying up…

❝ Kurt Fausch described the situation as a “wicked problem,” one with no good solution. “More water is pumped out every year than trickles back down into the aquifer from rain and snow,” he said. “We are basically drying out the Great Plains.”

Any ideas? Know any conservative politicians with any useful ideas? RTFA for more details, more sad news.
