Irrigation Investment and Disinvestment, 1975-77: A Report on a Landownership Follow-On Survey

摘要

An estimated 5.5 million acres were irrigated for the first time with an investment of $1.7 billion by more than 77,000 landowners during the period 1975-77. An estimated 1.2 million acres were removed from irrigation by more than 7,000 landowners during that period. Thus, irrigated acreage increased by about 4.3 million acres during the study period. About 1 million acres of the newly irrigated land came from non-cropland, thus adding to the cropland base. Only 23 percent of the land no longer irrigated was reported to be idle, 30 percent was in cropland, and 24 percent was used for pasture.
