Current Vehicle Fleet Inventory And Future Implementation Of A Centralized Electric Fleet At Portland State University, Dane Kovaleski
Current Vehicle Fleet Inventory And Future Implementation Of A Centralized Electric Fleet At Portland State University, Dane Kovaleski
Environmental Science and Management Professional Master's Project Reports
As the effects of climate change continue to impact the world, many institutions have developed climate action goals to reduce their effects on the environment. Portland State University (PSU) has committed to an 80% reduction of greenhouse gas emissions by 2030 and carbon neutrality by 2040. A part of this commitment must include looking at the contributions of transportation on campus to reduce carbon emissions. According to a greenhouse gas emissions report done by the Campus Planning and Sustainability Office in 2016, transportation contributed to 12% of total greenhouse gas emissions on campus.
This project aims to evaluate the management …
Factors Affecting Community Rating System Participation In The National Flood Insurance Program: A Case Study Of Texas, Ryan David Eddings
Factors Affecting Community Rating System Participation In The National Flood Insurance Program: A Case Study Of Texas, Ryan David Eddings
Dissertations and Theses
Since the 1960s, the frequency and cost of floods have, on average, increased in the United States. Concurrent with this increase in flood losses has been an increase in flood insurance claims paid out by the National Flood Insurance Program (NFIP). The existing literature shows that participation in the NFIP's Community Rating System (CRS) program successfully lowered flood losses and NFIP insurance claims in the participating communities. In spite of these successes, community participation in the CRS is low and the NFIP is currently more than $20 billion in debt. By identifying factors predicting participation and related barriers to entry …
Spatial Validation Of Agent-Based Models, Kristoffer Wikstrom, Hal T. Nelson
Spatial Validation Of Agent-Based Models, Kristoffer Wikstrom, Hal T. Nelson
Public Administration Faculty Publications and Presentations
This paper adapts an existing techno–social agent-based model (ABM) in order to develop a new framework for spatially validating ABMs. The ABM simulates citizen opposition to locally unwanted land uses, using historical data from an energy infrastructure siting process in Southern California. Spatial theory, as well as the model’s design, suggest that adequate validation requires multiple tests rather than relying solely on a single test-statistic. A pattern-oriented modeling approach was employed that first mapped real and simulated citizen comments across the US Census tract. The suite of spatial tests included Global Moran’s I, complemented with bivariate correlations, as well as …
Current Stormwater Practices And Future Implementation At Portland State University With The Uncertainty Of Climate Change, Evan Suemori, Alexandra Vargas Quiñones
Current Stormwater Practices And Future Implementation At Portland State University With The Uncertainty Of Climate Change, Evan Suemori, Alexandra Vargas Quiñones
Environmental Science and Management Professional Master's Project Reports
Stormwater runoff is one of the most critical environmental issues in urban areas and is only expected to worsen as climate change persists (EPA, 2016). When precipitation events occur, stormwater travels across impervious surfaces collecting soils and pollutants which can negatively impact water quality in receiving waters. Additionally, stormwater has human health impacts, specifically through flooding and the contamination of drinking water. According to the Intergovernmental Panel on Climate Change (IPCC), it has been determined that climate change will increase the frequency, intensity, and/or number of precipitation events in some regions, including the Pacific Northwest, and decrease in others (IPCC, …
Determinants Of Green Purchase Intentions Of Saudi Consumers, Amani Mohammed Kaadoor
Determinants Of Green Purchase Intentions Of Saudi Consumers, Amani Mohammed Kaadoor
Dissertations and Theses
Much of the research on how and why consumers engage in pro-environmental consumption has occurred in the wealthy countries of the West, where green markets are increasingly well established. Research in other economic and cultural context is sparse and points to large regional differences that cause some researchers to call key theoretical foundations, such as the Theory of Planned Behavior, into question. In response, this study investigates the factors that predict green purchase intention for food and personal care products in Saudi Arabia, a wealthy country with a rapidly growing population, severe environmental challenges, and a nascent green consumer market …

Collaboration And Evaluation In Urban Sustainability And Resilience Transformations: The Keys To A Just Transition?, Liliana Elizabeth Caughman
Dissertations and Theses
Climate has changed and will continue changing; city populations are swelling as urbanization continues to accelerate; extreme environmental events like heat waves and floods are becoming more severe and more common; and the climate justice movement is rapidly gaining momentum. It in this context that municipal governments find themselves urgently seeking solutions to transition cities from extractive, vulnerable, and unjust to sustainable, resilient, and equitable. The task is complex and will require systemic transformations across interconnected social, environmental, and economic infrastructures. Emerging theories regarding how to govern such massive changes suggest Transition Management strategies and the values of a just …
Unpacking The Process And Outcomes Of Ethical Markets: A Focus On Certified B Corporations, Renée Bogin Curtis
Unpacking The Process And Outcomes Of Ethical Markets: A Focus On Certified B Corporations, Renée Bogin Curtis
Dissertations and Theses
The growth in conscious consumption presents an opportunity to 1) better understand the potential outcomes of ethical market practices as a community-advocacy tool and 2) to consider potential policy considerations. The marketplace has increasingly become an arena for social action. This leads to the question of how can markets facilitate ethical business practices and community benefits? The recent rise of social benefit corporations warrants an evaluation of the outcomes of ethically-driven markets. Using a comparative research design and qualitative interview methods, this study examines certified Benefit Corporations (B Corps) in two selected cities: Philadelphia and Portland. Through interviews with B …
Real-Time Evaluation Of City–University Partnerships For Sustainability And Resilience, Liliana Elizabeth Caughman, Lauren Withycombe Keeler, Fletcher Beaudoin
Real-Time Evaluation Of City–University Partnerships For Sustainability And Resilience, Liliana Elizabeth Caughman, Lauren Withycombe Keeler, Fletcher Beaudoin
Institute for Sustainable Solutions Publications and Presentations
Cities face many challenges in their efforts to create more sustainable and resilient urban environments for their residents. Among these challenges is the structure of city administrations themselves. Partnerships between cities and universities are one way that cities can address some of the internal structural barriers to transformation. However, city–university partnerships do not necessarily generate transformative outcomes, and relationships between cities and universities are complicated by history, politics, and the structures the partnerships are attempting to overcome. In this paper, focus groups and trial evaluations from five city–university partnerships in three countries are used to develop a formative evaluation tool …
Do Corporate Owned Adaptive Learning Platforms Perpetuate Banking Style Learning? Integrating Technology For Activism Into Transformational Sustainability Education, Tina M. Garner
Leadership for Sustainability Education Comprehensive Papers
We live in a world that tends to be controlled by corporations. The public school system should be wary of the problems that corporate control has on education. Even though public schools should not have corporate influence, the fact remains that they do, and this perpetuates Freire's banking style learning. Through time, the corporate influence in education was through educational materials such as book sales. Since the decline of the use of books and the growth of the use of technologies, corporations have followed suit through the sales of Adaptive Learning Platforms. Through leveraging the technology which students enjoy using, …

Recent evidence suggests that many densely populated areas of the world will be uninhabitable in the coming century due to the depletion of resources, climate change, and increasing urbanization. This poses serious questions regarding the actions that require immediate attention, and opportunities to stave off massive losses of infrastructure, populations, and financial investments. The present study utilizes microclimate modeling to examine the role of landscape features as they affect ambient temperatures in one of the fastest growing regions of the world: Doha, Qatar. By modeling three study sites around Doha—one highly urbanized, one newly urbanizing, and one coastal low-density urbanized—the …

Reorganizing School Lunch For A More Just And Sustainable Food System In The Us, Jennifer Gaddis, Amy K. Coplen
Reorganizing School Lunch For A More Just And Sustainable Food System In The Us, Jennifer Gaddis, Amy K. Coplen
Urban Studies and Planning Faculty Publications and Presentations
Public school lunch programs in the United States are contested political terrains shaped by government agencies, civil society activists, and agri-food companies. The particular organization of these programs has consequences for public health, social justice, and ecological sustainability. This contribution draws on political economy, critical food studies, and feminist economics to analyze the US National School Lunch Program, one of the world's oldest and largest government-sponsored school lunch programs. It makes visible the social and environmental costs of the "heat-and-serve" economy, where widely used metrics consider only the speed and volume of service as productive work. This study demonstrates that …
The Dispute Over The Commons: Seed And Food Sovereignty As Decommodification In Chiapas, Mexico, Carol Frances HernáNdez RodríGuez
The Dispute Over The Commons: Seed And Food Sovereignty As Decommodification In Chiapas, Mexico, Carol Frances HernáNdez RodríGuez
Dissertations and Theses
Seeds have become one of the most contested resources in our society. Control over seeds has intensified under neoliberalism, and today four large multinational corporations control approximately 70 percent of the global seed market. In response to this concentration of corporate power, an international social movement has emerged around the concept of seed sovereignty, which reclaims seeds and biodiversity as commons and public goods. This study examines the relationship between the global dynamics of commodification and enclosure of seeds, and the seed sovereignty countermovement for decommodification. I approach this analysis through an ethnographic case study of one local seed sovereignty …

Hedgerows, flowering strips, and natural areas that are adjacent to agricultural land have been shown to benefit crop production, via the provision of insect pollinators that pollinate crops. However, we do not yet know the extent to which bee habitat in the form of urban gardens might contribute to pollination services in surrounding crops. We explored whether gardens might provision pollinators to adjacent agricultural areas by sampling bees from gardens in the Portland, Oregon metropolitan area, and estimating typical foraging distances in the context of commercialand residential-scale pollination-dependent crops up to 1000 m from garden study sites. We estimate that …

Deconstruction In Portland: Summary Of Activity, Emma Willingham, Peter Hulseman, Mike Paruszkiewicz
Northwest Economic Research Center Publications and Reports
On October 31st, 2016, the City of Portland instituted an ordinance requiring the deconstruction of all residential homes and duplexes built prior to 1917 or possessing a historical designation. Deconstruction is a relatively new industry, and with this local regulatory encouragement, several new contractors became certified to participate in the expanded market. This report provides background on the industry, largely from the 2016 report researched and written by the Northwest Economic Research Center (NERC) in anticipation of the requirement, and an examination of what has occurred in the year following the ordinance’s passage, using deconstruction and demolition permit data and …

Building Planner Commitment: Are California’S Sb 375 And Oregon’S Sb 1059 Models For Climate-Change Mitigation?, Keith Bartholomew, David Proffitt
TREC Final Reports
California’s Sustainable Communities and Climate Protection Act (SB 375) and the Oregon Sustainable Transportation Initiative (SB 1059) have made them the first states in the nation to try and reduce greenhouse gas (GHG) emissions using the transportation-planning process. Evaluating how these pioneering laws have changed local planning processes – as well as plans themselves – in each state provides insight into the laws’ effectiveness at changing development patterns in a way that reduces GHG emissions, without waiting decades to see the effects in the built environment. Both states’ laws require metropolitan planning organizations (MPOs) and the municipalities that comprise them …

Indigenous peoples, local communities, and other groups can use counter-mapping to make land claims, identify areas of desired access, or convey cultural values that diverge from the dominant paradigm. While sometimes created independently, counter-maps also can be formulated during public participation mapping events sponsored by natural resource planning agencies. Public participation mapping elicits values, uses, and meanings of landscapes from diverse stakeholders, yet individuals and advocacy groups can use the mapping process as an opportunity to make visible strongly held values and viewpoints. We present three cases from the Olympic Peninsula in Washington State to illustrate how stakeholders intentionally used …
Trade-Offs: The Production Of Sustainability In Households, Kirstin Marie Elizabeth Munro
Trade-Offs: The Production Of Sustainability In Households, Kirstin Marie Elizabeth Munro
Dissertations and Theses
Over the past half-century, environmental problems have become increasingly serious and seemingly intractable, and a careless, clueless, or contemptuous consumer is often portrayed as the root cause of this environmental decline. This study takes a different approach to evaluating the demand for resources by households, assessing possible pro-environmental paths forward through a study of highly ecologically-conscious households. By modeling "green" households as producers of sustainability rather than consumers of environmental products, the sustainability work that takes place in households is brought into focus. An investigation of household sustainability production makes possible the evaluation of the trade-offs inherent in these pro-environmental …

Knowing Nature In The City: Comparative Analysis Of Knowledge Systems Challenges Along The 'Eco-Techno' Spectrum Of Green Infrastructure In Portland & Baltimore, Annie Marissa Matsler
Dissertations and Theses
Green infrastructure development is desired in many municipalities because of its potential to address pressing environmental and social issues. However, despite technical optimism, institutional challenges create significant barriers to effective green infrastructure design, implementation, and maintenance. Institutional challenges stem from the disparate scales and facility types that make up the concept of green infrastructure, which span from large-scale natural areas to small engineered bioswales. Across these disparate facilities 1) different performance metrics are used, 2) different institutions have jurisdiction, and, 3) facility types are differentially classified as assets, producing epistemological and ontological variegation across the spectrum of green infrastructure that …

Advancing Rationality With Sustainability: An Analysis Of Agent-Based Simulation, Osman Goktug Tanrikulu
Hatfield Graduate Journal of Public Affairs
Today, falling trends of species and ecosystem in the world due to overconsumption and destruction of natural resources are at critical levels. It is vital for humanity to operate with sustainable and resilient modes of production and consumption. In this regard, this paper examines the basic premise of rationality and introduces sustainability as an advancement to the theoretical concept of rationality. Thus, a rational mindset and a sustainable mindset are compared under depletion of environmental resources. The understanding of rationality in the analysis is based on Garett Hardin’s (1968) ‘the tragedy of the commons’ model, in which actors are self-interested …

Mapping Meaningful Places On Washington’S Olympic Peninsula: Toward A Deeper Understanding Of Landscape Values, Lee Cerveny, Kelly Biedenweg, Rebecca J. Mclain
Institute for Sustainable Solutions Publications and Presentations
Landscape values mapping has been widely employed as a form of public participation GIS (PPGIS) in natural resource planning and decision-making to capture the complex array of values, uses, and interactions between people and landscapes. A landscape values typology has been commonly employed in the mapping of social and environmental values in a variety of management settings and scales. We explore how people attribute meanings and assign values to special places on the Olympic Peninsula (Washington, USA) using both a landscape values typology and qualitative responses about residents’ placerelationships. Using geographically referenced social values data collected in community meetings (n …

Recent evidence suggests that urban forms and materials can help to mediate temporal variation of microclimates and that landscape modifications can potentially reduce temperatures and increase accessibility to outdoor environments. To understand the relationship between urban form and temperature moderation, we examined the spatial and temporal variation of air temperature throughout one desert city—Doha, Qatar—by conducting vehicle traverses using highly resolved temperature and GPS data logs to determine spatial differences in summertime air temperatures. To help explain near-surface air temperatures using land cover variables, we employed three statistical approaches: Ordinary Least Squares (OLS), Regression Tree Analysis (RTA), and Random Forest …
Integrating Freight Into Livable Communities, Kristine M. Williams, Alexandria Carroll
Integrating Freight Into Livable Communities, Kristine M. Williams, Alexandria Carroll
TREC Final Reports
Where livability is a goal of the planning process, freight runs the risk of not being considered except as an afterthought or as something to be excluded. Yet, freight is an integral part of local economic development. Because economic prosperity is a key characteristic of livable communities, freight must be incorporated into the planning process. This study explores the relationship between freight and livability through a comprehensive literature review and case study research. The final report includes a menu of strategies and case study perspectives that highlight the importance of transportation and land use integration, interagency coordination, and context-sensitivity in …

Herbicide Resistance: Challenges For Farmers And Implications For The Environment, George Frisvold, David E. Ervin
Economics Faculty Publications and Presentations
Genetically modified, herbicide resistant (HR) crops offer not only improved weed control, but also the potential to reduce soil erosion and fossil fuel use and to allow substitution toward less toxic or persistent herbicides. The widespread adoption of HR crops, however, has reduced the diversity of weed control tactics and increased ecological selection pressure for weeds resistant to dominant herbicides. This has led to a dramatic rise of HR weeds in many cropping systems. Resistant weeds threaten the sustainability of HR crops, pose environmental risks from alternative weed control practices, are altering public and private R&D programs, and necessitate new …
