A New Era for Irrigation
"Irrigated agriculture has played a critical role in the economic and social development of the United States--but it is also at the root of increasing controversy. How can irrigation best make the transition into an era of increasing water scarcity? In A New Era for Irrigation, experts draw important conclusions about whether irrigation can continue to be the nation's most significant water user, what role the federal government should play, and what the irrigation industry must do to adapt to the conditions of the future. A New Era for Irrigation provides data, examples, and insightful commentary on issues such as:
Growing competition for water resources. Developments in technology and science.
The role of federal subsidies for crops and water. Uncertainties related to American Indian water rights issues.
Concern about environmental problems. And more".

Irrigation in the American West Area, Water and Economic Activity
"Irrigation is the defining characteristic of crop production
in the American West. Irrigated agriculture uses the most
freshwater (90 percent) of any economic sector in the West.
Surface-water sources such as streams, rivers, and lakes provide
68 percent of withdrawals while the remaining 32 percent are
obtained from groundwater sources. According to the 1997 Census of
Agriculture, 43 million acres of agricultural land were irrigated
in the West, and these lands produced 72 percent of crop sales on
only 27 percent of the total harvested crop acreage".
