Left Out To Dry: Understanding The Social Experiences Of Ground Depletion In Washington State's Columbia River Basin, Alexis Lisandro Guizar-Diaz

Dissertations and Theses

Millions of water wells worldwide risk running dry due to overpumping, drought, and climate change. This study adopts a political ecology framework to investigate how economic structures and power dynamics shape the effects of groundwater depletion in a highly impacted region. It is based on qualitative fieldwork conducted in the Odessa Aquifer region of Washington State. This agriculturally productive region has experienced severe groundwater depletion, endangering communities and threatening water supplies for many, as agribusiness has intensively used deep water wells to irrigate high-value crops. This research addresses three key questions: 1) How do residents and households excluded from irrigation …

Wildfire Risk Governance From The Bottom Up: Linking Local Planning Processes In Fragmented Landscapes, Matthew Hamilton, Max Nielsen-Pincus, Cody Evers

Environmental Science and Management Faculty Publications and Presentations

The growing scale of natural hazards highlights the need for models of governance capable of addressing risk across administrative boundaries. However, risk governance systems are often fragmented, decentralized, and sustained by informal linkages among local-level risk mitigation planning processes. Improving resilience to the effects of environmental change requires a better understanding of factors that contribute to these linkages. Using data on the patterns of participation of 10,199 individual stakeholders in 837 community wildfire protection plans (CWPPs) within the western U.S., we document the emergence of a locally clustered but spatially extensive wildfire risk governance network. Our evaluation of factors that …

Changing The Paradigm For Pesticide Resistance Management, David R. Shaw, Amy Asmus, Jill Schroeder, David Ervin

Economics Faculty Publications and Presentations

Collaborative action on the part of all stakeholders in pest management is essential to effectively address the challenges of pesticide resistance. The US Environmental Protection Agency, through its Pesticide Program Dialogue Committee, recently posted a report on pesticide resistance management and the role the Agency can play in these efforts. In this perspectives piece, we commend the Agency for acknowledging these needs, and encourage implementation of the recommendations. We urge all stakeholders to follow the example set by EPA to engage openly, listen to other stakeholders, and determine their role as part of the broader community that is needed to …

Radical Urban Natures: Mitigating Urban Heat With Nature-Based Techniques In Portland, Oregon, Heather Day-Melgar

Dissertations and Theses

Anthropogenic rising heat associated with climatic changes in the built environment has become a serious global issue. The built environment is often comprised of impermeable, paved surfaces, lack of vegetation to make way for development, tree removal, and loss or alteration of urban waterways, which leads to a degraded ecosystem for humans and non-human life, and less of an ability for carbon capture, all of which contribute to higher urban temperatures. This alteration of the existing natural environment leads to populations often unable to conceptualize that a built environment is still an ecosystem, and restoration is possible and necessary for …

The Project‑Partnership Cycle: Managing City‑University Partnerships For Urban Sustainability And Resilience Transformations, Liliana Elizabeth Caughman, Fletcher Beaudoin, Lauren Withycombe Keeler

Institute for Sustainable Solutions Publications and Presentations

Cities across the globe are striving to produce viable solutions to pressing urban sustainability and resilience problems. Despite aspirations, municipal governments often need additional support in terms of knowledge, capacity, or resources to achieve transformations. Partnerships between cities and universities are one mechanism for co-producing knowledge and achieving sustained progress on complex challenges. When properly structured and effectively managed, city-university partnerships (CUPs) are purported to increase transformative capacity in city administrations and support actions which accelerate urban transformations; but these outcomes are not always achieved. As CUPs grow in numbers, there is a pressing need to identify which principles and …

An Integrated Analysis Of Urban Sustainability In Portland: Issues, Indicators, Stakeholders, And Geospatial Assessment, Arun Kumar Pallathadka

Dissertations and Theses

This dissertation presents three individual studies that collectively explore the concept of urban sustainability. The research is grounded in the recognition that many cities worldwide are striving to achieve sustainable development, yet existing sustainability frameworks often lack comprehensive definition and consideration. Moreover, the existing sustainability frameworks and methods are often not clearly structured to allow for their replication and adaptation to meet the unique needs of diverse local settings. To address this gap, the dissertation utilizes the Social-Ecological-Technological Framework, with particular emphasis on equity, to investigate key issues in urban sustainability, such as indicators, stakeholder engagement, tradeoffs, and assessment. The …

University Honors Theses

This research examined the emotional responses elicited by different genres of environmental visual media (VM) trailers. Six undergraduate Environmental Science and Management student participants self-selected to watch trailers from three different genres of VM: a documentary film, a television series, and a narrative film. The goal of this research was to understand the extent people become aware of various environmental VM topics, how VM elicits emotional responses, the effectiveness of VM in promoting action, and to gain a better understanding of how producers and directors can potentially modify VM to have a greater impact on changing participants' attitudes toward climate …

Homelessness, Water Access, And Environmental Justice In An Urban Environment, Alicia Gamble

Environmental Science and Management Professional Master's Project Reports

Only in recent years has houselessness been viewed as an environmental justice issue, and little is understood about the environmental injustices of water insecurity among unhoused individuals, especially during the COVID-19 pandemic. In order to understand the environmental injustices (i.e., distributive, procedural, and recognition) of the water insecurity process using the cause-response-effect theoretical model, unhoused participants living near services were interviewed in Portland, Oregon about their lived experiences gaining access to water, the barriers they encounter when trying to access water, and the impacts that result from these barriers. Results revealed that COVID-19 was a barrier to water access and …

Climate Change Proposal: Coupling Equity And Scientific Rigor In Facing Global Warming, Rebecca Mcnicholas

University Honors Theses

Global warming has detrimental effects on the health and population of our planet. For years, scientists have known that in order to preserve the earth for future generations, it is necessary to adopt more sustainable practices that reduce greenhouse gas (GHG) emissions and waste. Policy makers across the globe have attempted to address the issue but have received pushback from the general public, industry and politicians on the other side, alike. Controversy surrounding necessary changes encompasses issues from livelihood, to affordability, to health equity, to taxation. This multifaceted problem cannot be solved with a simple solution; rather, it requires consideration …

Unequal Trust: Bottled Water Consumption, Distrust In Tap Water, And Economic And Racial Inequality In The United States, Daniel Jaffee

Sociology Faculty Publications and Presentations

Reviewing public health, nutrition, and social science literature, this article examines how bottled water consumption and spending in the United States differ along lines of race, ethnicity, and income, how these consumption patterns have changed in recent years, and how those shifts map onto perceptions of the safety and trustworthiness of tap water supplies, both before and since the Flint water disaster. It also addresses the differential impact of bottled water spending on household income. The findings challenge the truism that bottled water consumption is positively correlated with income, instead showing a bimodal racial and class consumption pattern that reflects …

Warming Of The Willamette River, 1850–Present: The Effects Of Climate Change And Direct Human Interventions, Stefan Talke, David Jay, Heida Diefenderfer

Civil and Environmental Engineering Faculty Publications and Presentations

Using archival research methods, we found and combined data from multiple sources to produce a unique, 140 year record of daily water temperature (Tw) in the lower Willamette River, Oregon (1881–1890, 1941–present). Additional daily weather and river flow records from the 1850s onwards are used to develop and validate a statistical regression model of Tw for 1850–2020. The model simulates the time-lagged response of Tw to air temperature and river flow, and is calibrated for three distinct time periods: the late 19th, mid 20th, and early 21st centuries. Results show that Tw has trended upwards at ~1.1 °C …

Forest Carbon Incentive Programs For Non-Industrial Private Forests In Oregon (Usa): Impacts Of Program Design On Willingness To Enroll And Landscape-Scale Program Outcomes, Rose A. Graves, Max Nielsen-Pincus, Ryan D. Haugo, Andres Holz

Environmental Science and Management Faculty Publications and Presentations

Privately-owned forests in the Pacific Northwest (PNW) are important potential carbon sinks and play a large role in carbon sequestration and storage. Non-industrial private forest (NIPF) owners constitute a substantial portion of overall forest landownership in productive regions of the PNW; however, little is known about their preferences for non-market incentive programs aimed at increased carbon storage and sequestration, specifically by limiting timber harvest, and how those preferences might impact the outcome of forest carbon programs. We simulated landscape-scale outcomes of hypothetical forest carbon incentive programs in western Oregon (USA) by combining empirical models of NIPF owners' participation with spatially …

Framing The Green New Deal And Climate Change: A Content Analysis Of The New York Times And The Wall Street Journal, Danielle Elizabeth Duffy

Dissertations and Theses

The importance of climate change recognition and need for action cannot be overstated. Climate change has historically been a partisan issue with an almost hyper focus on the (un)certainty of science, the need for action within a particular timeframe, and the cost of tackling the issue. With the contemporary relevance and salience of climate change, this content analysis explores emerging framing patterns in coverage of the Green New Deal and subsequent climate change references within news articles from the New York Times and Wall Street Journal in 2019. Frame typology from O'Neill et al. (2015) is used to explore the …

Performance Of An Environmentally-Aligned, Low Maintenance Flood Alleviation Scheme On The Burn Of Mosset, Forres, Scotland, Matthew F. Johnson, Patrick Edwards, Rachael Todd, Janine M. Castro, Colin R. Thorne

Environmental Science and Management Faculty Publications and Presentations

Flooding of the town of Forres, Scotland prompted the implementation of a flood alleviation scheme (FAS) featuring a low earth-fill dam constructed upstream of the town to create a flood retention area, limiting peak discharges entering the urban area. Flow through the dam is controlled by a weir, and it was recognised that if coarse sediment, large wood, and/or debris collected at the weir this could adversely affect its performance. To ensure reliable operation of the weir, the “Burn Management Works” (BMW) were designed to reconnect the embanked, elevated river channel to its floodplain, naturally retaining coarse sediment, large wood, …

Combating The Climate Crisis: Deconstructing Western Anthropocentricity And The Value Of Indigenous Teachings, Jessica K. St. Michael

University Honors Theses

This thesis will analyze prevailing Western perceptions of the natural environment and the historical construction of these beliefs, in an attempt to discern the root problems contributing to the present-day climate crisis. The dominant historical narratives of the West (such as Greco-Roman, and Christian) will be examined so as to demonstrate the trajectory of Western thought in regard to perceptions of the natural environment. Prominent theories on combating climate change in the modern era, put forth by scholars with expertise in relevant fields, will be examined and discussed, with a specific focus on the established dichotomy between man and nature, …

The Legacy Of Redlining: A Geospatial Analysis Of Environmental Burdens In Portland, Oregon, Warren Louis Gunn, Meenakshi Rao

University Honors Theses

Historically-redlined neighborhoods across the metropolitan United States -- most often socioeconomically disadvantaged communities of color -- have been shown in multiple studies to be disproportionately affected by environmental burdens, having greater exposure to air, water, and ground pollution as well as being subject to the "urban heat island" effect, among other disparities. Studies into the continuing environmental inequity present in these communities in Portland, Oregon specifically have addressed this phenomenon, finding that these neighborhoods are 8 degrees Fahrenheit warmer on average than their wealthier and (mostly) whiter counterparts, in large part due to a lack of green spaces and tree …

Hemp-Lime Insulation: A Climate Friendly Building Material, Ginger Rose Jensen

Student Research Symposium

It is critical to reduce greenhouse gas from the atmosphere to reduce the impacts of climate change. Oregon’s Climate Action Plan has established goals to reduce emissions by developing ‘Clean Buildings’ and increasing the CO₂ sequestered by the state's ‘Natural and Working Lands’. Carbon negative construction materials like hemp-lime insulation could contribute to both goals.

Hemp-lime is a non-structural insulation material made from crushed hemp hurd, a lime-based binder, and water. It is non-toxic and versatile alternative to traditional insulation materials. Hemp-lime was submitted to be added to the International Residential Codes (IRC) index in 2022. IRC approval would …

Engagement In Local And Collaborative Wildfire Risk Mitigation Planning Across The Western U.S.—Evaluating Participation And Diversity In Community Wildfire Protection Plans, Emily Palsa, Cody Evers, Matt Hamilton, Max Nielsen-Pincus

Environmental Science and Management Faculty Publications and Presentations

Since their introduction two decades ago, Community Wildfire Protection Plans (CWPPs) have become a common planning tool for improving community preparedness and risk mitigation in fire-prone regions, and for strengthening coordination among federal and state land management agencies, local government, and residents. While CWPPs have been the focus of case studies, there are limited large-scale studies to understand the extent of, and factors responsible for, variation in stakeholder participation—a core element of the CWPP model. This article describes the scale and scope of participation in CWPPs across the western United States. We provide a detailed account of participants in over …

Never Ask For A Lighter Rain But A Stronger Umbrella, Anurag Pande, Melissa Haeffner, Günter Blöschl, Mohammad Faiz Alam, Cyndi Castro, Giuliano Di Baldassarre, Fanny Frick-Trzebitzky, Rick Hogeboom, Heidi Kreibich, Multiple Additional Authors

Environmental Science and Management Faculty Publications and Presentations

In a recent editorial in the journal Nature Sustainability, the editors raised the concern that journal submissions on water studies appear too similar. The gist of the editorial: “too many publications and not enough ideas.” In this response, we contest this notion, and point to the numerous new ideas that result from taking a broader view of the water science field. Drawing inspiration from a recently hosted conference geared at transcending traditional disciplinary silos and forging new paradigms for water research, we are, in fact, enthusiastic and optimistic about the ways scientists are investigating political, economic, historical, and cultural intersections …

The Silence Of The Clams: Forestry Registered Pesticides As Multiple Stressors On Soft-Shell Clams., Alexandra G. Tissot, Elise F. Granek, Anne W. Thompson, Michelle L. Hladik, Patrick W. Moran, Kaegan Scully-Engelmeyer

Environmental Science and Management Faculty Publications and Presentations

Contaminants are ubiquitous in the environment, often reaching aquatic systems. Combinations of forestry use pesticides have been detected in both water and aquatic organism tissue samples in coastal systems. Yet, most toxicological studies focus on the effects of these pesticides individually, at high doses, and over acute time periods, which, while key for establishing toxicity and safe limits, are rarely environmentally realistic. We examined chronic (90 days) exposure by the soft-shell clam, Mya arenaria, to environmentally relevant concentrations of four pesticides registered for use in forestry (atrazine, 5 μg/L; hexazinone, 0.3 μg/L; indaziflam, 5 μg/L; and bifenthrin, 1.5 μg/g organic …

Mapping The Publics: The Production Of Spatial Knowledge And Public Interest, Paul Thomas Manson

Dissertations and Theses

Over the past decades, calls for comprehensively managing and planning ocean resources have emerged internationally and within the United States. Central to these calls is a drive to expand coastal and marine spatial planning with a particular focus on technologically mediated public involvement. These new public involvement technologies aim, more quickly and thoroughly, to solicit and analyze public values and existing uses of the coastal and marine environments. One particular technological innovation is the use of participatory geographic information systems (PGIS). These new tools allow for stakeholders, members of the public, and planning entities to collect, visualize, and interact with …

Planning For Future Fire: Scenario Analysis Of An Accelerated Fuel Reduction Plan For The Western United States, Alan A. Ager, Cody Evers, Michelle A. Day, Fermin J. Alcasena, Rachel Houtman

Environmental Science and Management Faculty Publications and Presentations

Recent fire seasons brought a new fire reality to the western US, and motivated federal agencies to explore scenarios for augmenting current fuel management and forest restoration in areas where fires might threaten critical resources and developed areas. To support this effort, we modeled the scheduling of an accelerated forest and fuel management scenario on 76 western US national forests. Specifically, we modeled a 10-year ramp up of current forest and fuel management that targeted the source of wildfire exposure to developed areas and simulated treatment in areas that accounted for 77% of the predicted exposure. We used a sample …

Online Activism And Real Life Environmentalism, Emily Grace Anderson

Dissertations and Theses

Past and present human activities have created and accelerated an array of environmental catastrophes and various systems in the environment remain under threat as a result of human behavior. In hopes of mitigating environmental consequences, a social movement has arisen to encourage people to behave in ways that are more environmentally sustainable. Research shows that individual behavior choices impact the environment, and this influence can be used to positively affect the environment through engagement in pro-environmental behavior. Like with many other social movements, the internet has been a tool in spreading awareness of a cause and allowing people the opportunity …

A Collaborative Approach To Cultural Resource Risk Assessment, Preservation, And Prioritization: A Case Study From Sauvie Island, Oregon, Phillip James Daily

Dissertations and Theses

New and increasing threats to cultural heritage resources have pushed archaeologists, land managers, and Indigenous peoples to develop strategies to identify at-risk resources, determine condition, vulnerabilities, and value of said resources, and then provide mitigation and preservation prioritizations and recommendations for the future. One such strategy is the risk assessment approach. Typically, to guide ongoing and future management of vulnerable cultural resources, risk assessments consider preexisting archaeological data, alongside geomorphological and hydrological landform characteristics, to prioritize sites for preservation. While such assessments have been conducted around the globe, they have not been widely applied on the Lower Columbia of Oregon …

Representation Justice As A Research Agenda For Socio-Hydrology And Water Governance, Melissa Haeffner, Dana E. Hellman, Alida Cantor, Idowu Ajibade, Vinka Oyanedel-Craver, Maura Kelly, Laura Schifman, Lisa Weasel

Environmental Science and Management Faculty Publications and Presentations

We propose representation justice as a theoretical lens for socio-hydrology and water governance studies. An exploratory survey of 496 water sector employees in the United States revealed that self-identifying females felt more strongly discriminated against due to their gender and other social factors, compared to self-identifying males. Responses unveiled how macro- and microaggressions impede career pathways to leadership positions and, therefore, representation. We identify ways in which socio-hydrology can benefit from a representation justice lens by considering the following: (1) how power and politics shape the composition of the water sector and decision-making processes; (2) how available quantitative data do …

Participatory Gis Mapping Highlights Indirect Use And Existence Values Of Coastal Resources And Marine Conservation Areas, Kaegan M. Scully‐Engelmeyer, Elise F. Granek, Max Nielsen-Pincus, Greg Brown

Environmental Science and Management Faculty Publications and Presentations

Consideration of social and cultural dimensions in coastal and marine planning has increased and ecosystem services provide important framing to investigate values and priorities associated with these systems. Research efforts in coastal communities offer insights on social dimensions of ocean and coastal management decisions, but questions remain about how demographics and geographic residence affect perceptions of marine resources and management. We conducted and analyzed a public participation geographic information system (PPGIS) mapping survey of Oregon residents to capture uses and perceived values of coastal and marine areas. We measured coastal values, explored regional differences in those values, and identified a …
