The overarching aim of this dissertation is to evaluate Geodesign as a planning approach for American Indian communities in the American Southwest. There has been a call amongst indigenous planners for a planning approach that prioritizes indigenous and community values and traditions while incorporating Western planning techniques. Case studies from communities in the Navajo Nation and the Tohono O’odham Nation are used to evaluate Geodesign because they possess sovereign powers of self-government within their reservation boundaries and have historical and technical barriers that have limited land use planning efforts. This research aimed to increase the knowledge base of indigenous planning, participatory Geographic information systems (GIS), resiliency, and Geodesign in three ways. First, the research examines how Geodesign can incorporate indigenous values within a community-based land use plan. Results showed overwhelmingly that indigenous participants felt that the resulting plan reflected their traditions and values, that the community voice was heard, and that Geodesign would be a recommended planning approach for other indigenous communities. Second, the research examined the degree in which Geodesign could incorporate local knowledge in planning and build resiliency against natural hazards such as flooding. Participants identified local hazards, actively engaged in developing strategies to mitigate flood risk, and utilized spatial assessments to plan for a more flood resilient region. Finally, the research examined the role of the planner in conducting Geodesign planning efforts and how Geodesign can empower marginalized communities to engage in the planning process using Arnstein’s ladder as an evaluation tool. Results demonstrated that outside professional planners, scientists, and geospatial analysts needed to assume the role of a facilitator, decision making resource, and a capacity builder over traditional roles of being the plan maker. This research also showed that Geodesign came much closer to meeting American Indian community expectations for public participation in decision making than previous planning efforts. This research demonstrated that Geodesign planning approaches could be utilized by American Indian communities to assume control of the planning process according to local values, traditions, and culture while meeting rigorous Western planning standards.

Disparities in access to healthy food are a key public health concern in the United States (U.S.) Food access is considered as a critical element of food insecurity. Food insecurity can often be prevalent in a region due to lack of healthy food outlets as well as inequitable access to healthy food outlets. A large body of literature pertaining to access to healthy food has reported that conventional food outlets such as supermarkets and large grocery stores may not be equitably distributed across different neighborhoods in a region. There has been limited research on local food access patterns. Despite the few studies focused on access to individual types of local food outlets, such as farmers markets, little is known about whether such access varies among different types of local food outlets and how such access patterns compare with the uneven access to conventional food outlets. This study uses Maricopa County, one of the largest counties in Arizona, as a case study to examine the spatial patterns of access to conventional food markets (i.e. supermarkets or large grocery stores) and four different types of local food outlets, including farmers market, community garden, community supported agriculture (CSA) and mobile food markets. By analyzing the association between healthy food access and neighborhood characteristics, the study suggests that the local food system has a great potential in providing healthy food access to low-income and minority populations of the County than conventional food outlets. The study provides important insights into the way different types of local food outlets offer their availability in space and whether they are more equitable in serving underserved neighborhoods. The findings from this study can assist both government agencies and city planner formulate strategies to improve access to healthy food in disadvantaged neighborhoods.

The study presented in this article adds to the body of research on the socio-cultural dimension of sustainable cities by looking at the efforts of the City of Freiburg, Germany to create neighborhoods that acknowledge the importance of the social dimension of sustainable development. The research in this article is centered on evaluating the social responses of living in Freiburg’s two recognized sustainable neighborhoods Rieselfeld and Vauban. The study focuses on the motivational factors that prompted todays residents of the two neighborhoods to move there in the first place, their level of satisfaction living there now, and their perceived social interactions and level of community engagement. Result show that satisfaction with living in a place and reinforcing its assets through social resiliency or livability can result in long-term community staying power. In general, there were few differences in preferences ratings of physical and social assets between the two communities. The levels of importance of social factors contributing to place satisfaction and staying power were not significantly different in both neighbor-hoods. Having a “cluster” of social factors present that were important to residents contributed significantly to place satisfaction. In fact, survey results showed that it was these social factors that were seen as more important to place satisfaction than the physical attributes of sustainable developments.

This report describes the process by which I created a concise but comprehensive online source of information about best practices in sustainability for urban planners. The goal of the project was to provide accessible information that would help planners in ways that help them comprehend and implement sustainable solutions to common planning problems that are found throughout the United States. To create the website, I researched methods for communicating clearly to planners, took a graduate course in communicating about sustainability, and drew on information that I had compiled on sustainable solutions for transportation, economy, water, green space, and governance.
