Irrigated acreage has shifted East since 1997, though total U.S. irrigated acreage has remained flat
In the United States, 54.9 million acres were irrigated in 2022, down slightly from 56.3 million acres in 1997. This modest decline conceals significant regional changes in recent decades. California’s irrigated acreage decreased from 8.8 to 8.2 million acres between 1997 and 2022. … The decrease in irrigated area in the West—where a generally arid climate means most crops require irrigation—primarily reflects surface and groundwater shortages due to drought and groundwater depletion in the face of competing demands for water. In some areas, urbanization has also contributed to this shift.
