Potential economic impacts of irrigation-water reductions estimated for Sacramento Valley.

摘要

In the Sacramento Valley, California, USA, irrigation water is vital to agriculture and agriculture is vital to local economies. This study investigates these relationships by asking: If surface irrigation water were cut by 25%, what would be the economic impacts on farmers and on communities?

In most regions and for most crops, a cut in irrigation water would cause a modest acreage reduction of up to 3%. Overall crop-revenue losses for core regions would total
