Irrigated acreage
has expanded across the Nation over
the decades
Over the past 140 years,
the number of acres irrigated has increased
steadily, with only three interruptions.
The last decline, in the later 1980s,
was due to drought and policy-imposed
land-idling requirements. Growth in
recent years has slowed, relative to
the longrun trend. Double-digit rates
of growth in Eastern irrigation—first
recorded in 1900 as “rice lands”—since
the mid-1980s have more than offset
recent declines in the West.
