Keith talks with Francisco Molinar, District Conservationist with the Natural Resources Conservation Service, U.S. Department of Agriculture.  Molinar is an agricultural engineer, and he talks about water conservation in the desert.  Some crops actually benefit from the hot, dry conditions in the Chihuahuan Desert, but specialized irrigation and  land-leveling techniques will be crucial in conserving water in the future.  Aired Jan. 27, 2013.
