In the United States, irrigation’s eastward spread

Fascinating piece by Brett Walton about the eastward spread of U.S. irrigation:

The canals, reservoirs, pumps, and pivoting sprinklers that transformed the American West in the 20th century from desert and grassland into the nation’s primary fruit and vegetable producing region are spreading eastward.

From the Deep South, the Mississippi River Delta, and across the Midwest, the basic equipment of modern irrigated agriculture is producing more reliable harvests, more productive use of scarce water supplies, and bigger paychecks. Just as in the West, eastern farmers also say irrigation is a tool for managing risk, providing insurance against erratic rainfall and rising temperatures brought by a warming world.

Significant implications, the entire thing is worth a click.
