Should We Tighten Our Belts?



The title of this post might indicate that it's about consuming fewer empty calories. It isn't. It's another rant about water.

Each summer we drive across western Kansas on our way to Dennis’s favorite fly-fishing spot in the Rocky Mountains. Along I-70 Highway we see grain elevators and church spires marking tiny towns.  Except for the city of Hayes, population 21,038, much of the landscape consists of dry cropland where center-pivot irrigation rigs make rainbows in the dry western air.

If not for the Ogallala Aquifer [1] one of the world’s largest natural water reservoirs, farming in this semi-arid area would be somewhere between difficult and impossible The Ogallala is a ”fossil aquifer,” [2] which underlies a deep layer of rock. It stretches from Nebraska to Texas. Water in the aquifer is ancient, much of it accumulated during the time when mastodons roamed these parts.

Our government's misguided push for farmers to produce more corn to make ethanol has encouraged western Kansas farmers to plant corn, the thirstiest of crops. Deep wells that tap the Ogallala Aquifer and powerful pumps enable them to cash in on the ethanol craze. If you have flown over the area, you may have observed the crop circles this irrigation creates.


But here’s the rub: the Ogallala Aquifer is being depleted and cannot be replaced in the foreseeable future. In several parts of Kansas, depletion is more than sixty percent. [3]

From Nebraska to Texas, the Ogallala Aquifer provides fresh water for twenty percent of the wheat, corn, cattle, and cotton produced in the United States. Moreover, 82 percent of the people in the area rely on the aquifer for their water. Obviously conservation is called for, but recently five western Kansas counties rejected a plan to conserve the Aquifer. [4] The plan would have reduced  their usage of the aquifer by twenty percent. [5]

Climate change predictions say that Kansas eventually will become a desert. In the meantime, western Kansa farmers are rapidly using up the only pristine water in the state. It seems important to remember that 82 percent of communities will have no water. Furthermore, let us remember that Kansas produces twenty percent of the wheat grown in the United States. How will failure of the Ogallala affect the price of the bead on our tables? We'd better tighten our belts.

‘Nuff said. I promise not to rant about water for at least another month.
