U.S. Irrigation Pushed Eastward By Drought and Financial Risks
U.S. Irrigation Pushed Eastward By Drought and Financial Risks
 

Dear *|FNAME|*,

Arkansas added two million acres of irrigated farmland in the last two decades and now is the third-largest irrigation state in the United States. But in growing acres of rice and cotton, farmers have depleted the state's primary aquifer by a quarter. Two canal projects, at a cost of $US 1.3 billion, will wean farmers from unsustainable groundwater pumping.

Arkansas is an extreme example, but the state embodies a national trend. Irrigation, long the domain of the U.S. West, is spreading eastward. This week Circle of Blue reports on the benefits and consequences of the irrigation shift.

A golden circle, this one near Edson, Kansas, is the tell-tale sign of an irrigated corn field ready for harvest. Farmers in the Great Plains produce some of the highest corn yields in the world thanks in part to abundant water supplies from the Ogallala Aquifer. The aquifer, however, is draining away because more water is pumped out than filters back in.

Hydro Resources, a well-drilling contractor, works around the clock to punch new holes in the Ogallala Aquifer in Kansas. The Ogallala, the primary water source in the Great Plains, is declining because billions of gallons are pumped out each year to irrigate corn, soybeans, wheat, and cotton.
