Description
It is widely recognized that, compared to others, minority and low-income populations are more exposed to environmental burdens and unwanted land uses like waste facilities. To prevent these injustices, cities and industry need to recognize these potential problems in the siting process and work to address them. I studied Phoenix, AZ, which has historically suffered from environmental justice issues. I examined whether Phoenix considered environmental justice concerns when siting their newest landfill (SR-85) and transfer station (North Gateway Transfer Station). Additionally, I assessed current views on sustainability from members of the Phoenix Transportation and Infrastructure Subcommittee and of decision-makers in the Public Works Department and Solid Waste Division. Using a mixed methods approach consisting of interviews, document analysis, and a demographic assessment of census tracts, I addressed two main research questions:
1. Do the distributions and siting processes of environmental burdens from SR-85 and North Gateway Transfer Station constitute a case of environmental injustice according to commonly held definitions?
2. Do current Solid Waste and council members on the Transportation and Infrastructure subcommittee consider environmental justice, defined as stakeholder engagement, to be a part of sustainability?
The results show that the distribution and siting processes of environmental burdens from these facilities may constitute a case of environmental injustice. While city officials do involve stakeholders in siting decisions, the effects of this involvement is unclear. An analysis of long-term demographic data, however, revealed no significant racial, ethnic, or economic effects due to the locations of the SR-85 and North Gateway Transfer Station.
Interviews with current members of the Transportation and Infrastructure Subcommittee, Public Works Department, and Solid Waste Division indicated that Phoenix’s decision-makers don’t consider environmental justice as part of sustainability. However, they seem to consider stakeholder engagement as important for decision-making.
To help mitigate future injustices, Phoenix needs buffer zone policies for waste facilities and stakeholder engagement policies for decision-making to ensure the public is engaged appropriately in all circumstances. Enacting these policies will help Phoenix become both a more sustainable city and one in which stakeholders have the opportunity to provide feedback and are given decision-making power.

Description
Humans have modified land systems for centuries in pursuit of a wide range of social and ecological benefits. Recent decades have seen an increase in the magnitude and scale of land system modification (e.g., the Anthropocene) but also a growing recognition and interest in generating land systems that balance environmental and human well-being. This dissertation focused on three case studies operating at distinctive spatial scales in which broad socio-economic or political-institutional drivers affected land systems, with consequences for the environmental conditions of that system. Employing a land system architecture (LSA) framework and using landscape metrics to quantify landscape composition and configuration from satellite imagery, each case linked these drivers to changes in LSA and environmental outcomes.
The first paper of this dissertation found that divergent design intentions lead to unique trajectories for LSA, the urban heat island effect, and bird community at two urban riparian sites in the Phoenix metropolitan area. The second paper examined institutional shifts that occurred during Cuba’s “special period in time of peace” and found that the resulting land tenure changes both modified and maintained the LSA of the country, changing cropland but preserving forest land. The third paper found that globalized forces may be contributing to the homogenizing urban form of large, populous cities in China, India, and the United States—especially for the ten largest cities in each country—with implications for surface urban heat island intensity. Expanding knowledge on social drivers of land system and environmental change provides insights on designing landscapes that optimize for a range of social and ecological trade-offs.
