Description
South Mountain is the largest municipal park in the nation. It is a bundled amenity, providing a series of linked services to the surrounding communities. A dataset of 19,209 homes in 155 neighborhoods within three miles of the park was utilized in order to complete a hedonic estimation for two nearby urban villages, Ahwatukee Foothills and South Mountain Village. Measures of access include proximity to the park, trailhead access, and adjacency to the park. Two regressions were estimated, the first including lot characteristics and subdivision fixed effects and the second using the coefficients for each subdivision as the dependent variable. These estimates describe how the location of a house in a subdivision contributes to its conditional mean price. As a result they offer a direct basis for capturing amenities measured at the neighborhood scale on home values. Park proximity, trailhead access and adjacency were found to significantly influence the price of homes at the 5% confidence level in Ahwatukee, but not in South Mountain Village. The results of this study can be applied to issues of environmental justice and park access in determining which areas and attributes of the park are associated with a high premium. Though South Mountain was preserved some time ago, development and future preservation in the City of Phoenix can be informed by such studies.

Description
Water scarcity in the Western United States has been the focus of recent policy discussion. Researchers and policymakers agree that the implications of water scarcity are severe and widespread, and as such have stressed the importance of addressing water allocation in the short term and long term. However, this urgency has led to some short-term solutions, like rotational fallowing, being implemented without evaluation, or some long-term solutions, like re-structuring of rights, being suggested without precedent. This dissertation aims at reducing the gap between proposed solutions, existing data, and program evaluation by developing and analyzing two novel datasets useful for causal identification, evaluating both a long-term and short-term approach to water scarcity with these data, and finally demonstrating the ability of overlapping institutions to respond to increasing weather variability. Chapter 1 evaluates a short-term approach, rotational fallowing, and identifies the impact of this approach on water savings. Chapter 2 develops novel trade panel data and exploits the only share-based water market in the US: the Colorado-Big Thompson Project. This chapter compares trade and crop choice outside of the CBT, to those same outcomes within the CBT, and identifies the differences. Chapter 3 expands on crop choice within the CBT and identifies the extent to which overlapping institutions can mediate weather variability compared to prior appropriation.

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.
