Description
With the projected population growth, the need to produce higher agricultural yield to meet projected demand is hindered by water scarcity. Out of many the approaches that could be implemented to meet the water gap, intensification of agriculture through adoption of advanced agricultural irrigation techniques is the focus for this research. Current high water consumption by agricultural sector in Arizona is due to historical dominance in the state economy and established water rights. Efficiency gained in agricultural water use in Arizona has the most potential to reduce the overall water consumption. This research studies the agricultural sector and water management of several counties in Arizona (Maricopa, Pinal, and Yuma). Several research approaches are employed: modeling of agricultural technology adoption using replicator dynamics, interview with water managers and farmers, and Arizona water management law and history review. Using systems thinking, the components of the local farming environment are documented through socio-ecological system/robustness lenses. The replicator dynamics model is employed to evaluate possible conditions in which water efficient agricultural irrigation systems proliferate. The evaluation of conditions that promote the shift towards advanced irrigation technology is conducted through a combination of literature review, interview data, and model analysis. Systematic shift from the currently dominant flood irrigation toward a more water efficient irrigation technologies could be attributed to the followings: the increase in advanced irrigation technology yield efficiency; the reduction of advanced irrigation technology implementation and maintenance cost; the change in growing higher value crop; and the change in growing/harvesting time where there is less competition from other states. Insights learned will further the knowledge useful for this arid state's agricultural policy decision making that will both adhere to the water management goals and meet the projected food production and demand gap.

Description
Postwar suburban sprawl resulted in environmental consequences that engendered backlash from those concerned about the quality life in the places they lived, played, and worked. Few cities grew as rapidly as Phoenix and therefore the city offers an important case study to evaluate the success and limits of environmentalism in shaping urban growth in the postwar period.
Using three episodes looking at sanitation and public health, open space preservation, and urban transportation, I argue three factors played a critical role in determining the extent to which environmental values were incorporated into Phoenix's urban growth policy. First, the degree to which environmental values influenced urban policy depends on the degree to which they fit into the Southwestern suburban lifestyle. A desire for low-density development and quality of life amenities like outdoor recreation resulted in decisions to extend municipal sewers further into the desert, the creation of a mountain preserve system, and freeways as the primary mode of travel in the city. Second, federal policy and the availability of funds guided policies pursued by Phoenix officials to deal with the unintended environmental impacts of growth. For example, federal dollars provided one-third of the funds for the construction of a centralized sewage treatment plant, half the funds to save Camelback Mountain and ninety percent of the construction costs for the West Papago-Inner Loop. Lastly, policy alternatives needed broad and diverse public support, as the public played a critical role, through bond approvals and votes, as well as grassroots campaigning, in integrating environmental values into urban growth policy. Public advocacy campaigns played an important role in setting the policy agenda and framing the policy issues that shaped policy alternatives and the public's receptivity to those choices.
Urban policy decisions are part of a dynamic and ongoing process, where previous decisions result in new challenges that provide an opportunity for debate, and the incorporation of new social values into the decision-making process. While twenty-first century challenges require responses that reflect contemporary macroeconomic factors and social values, the postwar period demonstrates the need for inclusive, collaborative, and anticipatory decision-making.
