A brown bear's response to human activities varies …

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 …

Lights, Camera, Climate Action: Investigating Emotional Responses To Climate Change Trailers (Documentary, Television, & Narrative Film), Erik Daniel Schell Devore

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 …

The Use And Influence Of Health Indicators In Municipal Transportation Plans, Kelly Christine Rodgers

Dissertations and Theses

Transportation is an important social determinant of health that shapes the places where people "live, learn, work, and play" to the extent that an individual's zip code better predicts their health than their genetic code. Researchers and practitioners have called for the use of health indicators in transportation as one way to integrate public health concerns into transportation. The underlying hope is that new organizational routines, such as measuring and tracking indicators, can translate policy goals into policy practice. However, it is unclear how indicators are used and what impact they have on policy--the creation or modification of policies and …

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 …

Legal Geographies, Caroline Griffith, Sarah Klosterkamp, Alida Cantor, Austin Kocher

Geography Faculty Publications and Presentations

This encyclopedia entry defines and discusses legal geography. Legal geography is an interdisciplinary area of scholarship that focuses on the intersections and co-constitution between law and space and place: that is, how law and legal processes produce space/place, and how particular places in turn influence law. Rather than thinking of law as an abstract, universal, a-spatial set of rules, legal geography examines the ways in which law is situated in place, and how places are shaped by legal practices and processes.

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 …

Factors Influencing Terrestriality In Primates Of The Americas And Madagascar, Timothy M. Eppley, Selwyn Hoeks, Colin A. Chapman, Joerg U. Ganzhorn, Katie Hall, Megan A. Owen, Dara B. Adams, Néstor Allgas, Multiple Additional Authors

Anthropology Faculty Publications and Presentations

Among mammals, the order Primates is exceptional in having a high taxonomic richness in which the taxa are arboreal, semiterrestrial, or terrestrial. Although habitual terrestriality is pervasive among the apes and African and Asian monkeys (catarrhines), it is largely absent among monkeys of the Americas (platyrrhines), as well as galagos, lemurs, and lorises (strepsirrhines), which are mostly arboreal. Numerous ecological drivers and species-specific factors are suggested to set the conditions for an evolutionary shift from arboreality to terrestriality, and current environmental conditions may provide analogous scenarios to those transitional periods. Therefore, we investigated predominantly arboreal, diurnal primate genera from the …

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 …

Teaching Fisheries Bycatch: Exploring Economic And Behavioral Drivers Of Bycatch Through A Classroom Game, Mitch B. Priestley, J. Forrest Williams, Sahan Dissanayake

Economics Faculty Publications and Presentations

This paper presents a pedagogical exercise to explore the economics of price-based fisheries bycatch. In the exercise students experience the economic incentives that lead to bycatch due to highgrading; the discarding of low-value fish. We first discuss existing fisheries economics pedagogical activities and how our exercise is distinct. We then identify over forty economics, environmental studies, geography, management, and philosophy courses where the exercise could be played. Next, we describe the game and share results and student feedback. Finally, we provide discussion prompts and extensions to illustrate how incentives and policies can change fishing behavior to lead to sustainable fisheries.

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 …

A Pilot Study Considering Ecoroofs As Therapeutic Landscapes, Olyssa Starry, Arjun Viray, Brenna Park-Egan, Amber Terway, Timothy Oxendahl, Tina Dawn Lillian Burdsall

Sociology Faculty Publications and Presentations

The potential for urban open spaces to convey therapeutic benefits is increasingly substantiated. More work is needed to specifically consider how low impact designs to manage stormwater such as ecoroofs perform in this context. Here, we report on a pilot study addressing: (1) factors determining whether a hospital has an ecoroof, and (2) how ecoroofs might convey therapeutic benefits. We utilized a mixed methods approach which encompassed phone interviews of hospital ecoroof managers as well as analysis of national hospital databases. We also conducted a local case study which compared cortisol samples and stress indicators from patients, staff, and caregivers …

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 …

Can Diatom Motility Indices Reflect Excess Fine Sediment Condition In Streams?, Christine L. Weilhoefer, Yangdong Pan

Environmental Science and Management Faculty Publications and Presentations

The diatom motility trait is widely used in bioassessment studies, however, there is no strong consensus as to what environmental conditions diatom motility reflects. We used random forest models to explore the behavior of several diatom-based motility indices and examined whether stronger diatom motility-environmental relationships could be developed by controlling for environmental factors that influence natural sediment loads and factors that co-occur with anthropogenic sediment loading. Across the study area, median values of most stressors were low; streambed fine sediments ranged from 0 to 100% (median: 6.7%) and total phosphorus concentrations ranged from 0 to 2587 µg L−1 (median: 17 …

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, …

It provides context for Carpio Whiting's accomplishments as an elected official in Oregon by describing her childhood in Chicago and her formative years in California, particularly how growing up Filipino American shaped her as an adult. As such, this thesis engages themes of gender, race, and class in historical scholarship. The thesis focuses on Carpio Whiting's life in Oregon and explores the opportunities and challenges facing women as they …

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 …

“From The Beginning Of Time”: The Colonial Reconfiguration Of Native Habitats And Indigenous Resource Practices On The British Columbia Coast, Chief Adam Dick (Kwaxsistalla Wathl’Thla), Daisy Sewid-Smith (Mayanilth), Kim Recalma-Clutesi, Douglas Deur, N.J. Turner (Galitsimġa)

Anthropology Faculty Publications and Presentations

Indigenous Peoples’ lives, cultures, and values are defined largely by their long-term relationships with the lands, waters, and lifeforms of their territories. Their stories, names, ceremonies, and connections with the plants and animals on which they have depended over countless generations are cornerstones of their knowledge systems, systems of governance and decision-making, traditions of intergenerational knowledge transmission, and values and responsibilities associated with natural and human domains alike. For First Nations of North America’s Northwest Coast, as for many other Indigenous Peoples, the arrival of European newcomers disrupted both the natural world and associated cultural practices in interconnected ways. The …

Tradeoffs And Synergies Across Global Climate Change Adaptations In The Food‐Energy‐Water Nexus, Sarah Torhan, Caitlin A. Grady, Idowu Ajibade, Eranga K. Galappaththi, Rebecca R. Hernandez, Justice I. Musah‐Surugu, A. M. Nunbogu, A. C. Segnon, Multiple Additional Authors

Geography Faculty Publications and Presentations

Food-energy-water (FEW) systems are increasingly vulnerable to natural hazards and climate change risks, yet humans depend on these systems for their daily needs, wellbeing, and survival. We investigated how adaptations related to FEW vulnerabilities are occurring and what the global community can learn about the interactions across these adaptations. We conducted a global analysis of a data set derived from scientific literature to present the first large scale assessment (n = 1,204) of evidence-based FEW-related climate adaptations. We found that the most frequently reported adaptations to FEW vulnerabilities by continent occurred in Africa (n = 495) and Asia (n = …
