Arizona agriculture faces many changes in the near future. One of the most imminent changes will come from the enactment of the 1980 Arizona Groundwater Management Act. The 1980 AGWMA is designed ultimately to curtail the use of groundwater in Arizona. Agriculture will be affected since this sector used approximately 87 percent of all water in the State in 1980. This study reports on the possible effects that a proposed pump tax and water duty policy would have on agriculture within the Phoenix Active Management Area. The PAMA is one of four such areas in the State that have been identified as needing groundwater use management. The results of this study indicate that the proposed water duty is more effective in curbing groundwater use than the proposed pump tax. Investment in more water application efficient irrigation technologies is also important in this study. However, substantial amounts of capital investment funds will be needed to begin this investment.Type

Residential demand for water in the Phoenix metropolitan areaResidential demand for water is an important component in determining water consumption, water prices and water regulation. The objective of this thesis is to derive the residential demand for water in the Phoenix metropolitan area. The demand curves that will be measured can be used by research and industry to aid them in water pricing and water conservation.

Optimization of runoff agriculture on reclaimed mine landsOptimization of runoff agriculture involves the selection of a crop whose water requirements correspond to the precipitation patterns of the area; the selection of a runoff treatment which, when applied to the catchment area, produces the greatest amount of water at the lowest cost; and the establishment of the ratio of catchment area to crop area. A model is presented which utilizes linear programming and watershed cropland simulation to select the best suited crop and runoff treatment for the system being considered. The model is then modified to determine the optimum catchment area ratio to be used. The model was applied to the reclaimed coal mine lands on the Black Mesa of northern Arizona. Results show that maximum economic returns can be obtained for conventional irrigated agriculture by using a ratio of 55 acres of catchment area with no runoff treatment to one acre of cropland producing corn. The use of carry-over pond storage to allow for supplemental irrigation is prohibited due to high evaporation rates on the Black Mesa. By reducing the corn crop density from the conventional 20,000 plants per acre to 5,000 plants per acre, the catchment area ratio can be reduced to an apparent ratio of 13:1. Hopi Indian farmers on the Black Mesa use a density of 5,000 plants per acre for cultivating a highly adapted strain of Indian corn.
