AbstractThe Arizona Groundwater Management Act (GMA) restricts the quantity of groundwater which farmers may use annually. The act also requires that a withdrawal fee be paid for each acre-foot of groundwater used. The impact of these policies on agricultural income and groundwater use in the Phoenix Active Management Area is estimated. A linear programming model is used to simulate the typical farm's response to GMA policy over the period from 1990 to 2025. The impacts of two possible revisions of GMA policy are also considered. One simulation estimates the impacts resulting from the elimination of urban conservation programs. A second scenario considers elimination of agricultural conservation measures. Results indicate that the GMA agricultural conservation program will generate only small changes in income and groundwater use.
