   Water Challenges




 Declining water quantity & quality

 Growing global demand for food and feeds

 Global warming

 Increased pressure on agricultural lands

The Ogallala Aquifer

     Provides 30% of total withdrawals from all US
      aquifers

  Texas High Plains
   Over 95% of the water pumped
    is for irrigated agriculture

     Future Constraints:
         Government regulation
         Municipal uses
         Water quality
         Energy costs
