Stormwater Capture In The Built Watershed: Fostering Public Awareness Of Water Conservation Through A Parcel-Level Approach To Stormwater Management, Benjamin Rigby

Pitzer Senior Theses

As California contends with climate change and more extreme cycles of drought and deluge, water management agencies and conservation groups are looking towards solutions to the decreasing reliability of imported water supplies. Stormwater has historically been perceived as a threat to development but when captured properly, it presents a resource that can augment local water supplies. Solutions to water supply issues in California have traditionally employed technical and centrally controlled methods for importing water, but there is a growing understanding that parcel-level capture through vegetated swales presents an opportunity for reducing the impact that development has on California’s hydrology. Vegetated …

“It’S Not Easy Being Green”: Predictors Of Pro-Environmental Behaviors Among College Students, Morgan Laner

Honors Program Theses

This study looks at the different predictors of the pro-environmental behaviors of undergraduate college students at a small, urban, private liberal arts college in Florida. A total of 437 students reported their environmental attitudes, subjective norms, intentions, perceived behavioral control, and pro-environmental behaviors. Results shows that the sample population replicates the relationships of the theory of planned behavior framework. Attitudes were the strongest predictors of intentions, which in turn had a positive, moderately strong relationship with pro-environmental behavior. Men were found to have higher means for intentions and attitudes than women. Understanding the perceptions and behaviors of students can help …

The Sovereign Signifier: Agamben And The Nonhuman - Chapter, Paul Eisenstein

Faculty Books

This book initiates the discussion between psychoanalysis and recent humanist and social scientific interest in a fundamental contemporary topic – the nonhuman. The authors question where we situate the subject (as distinct from the human) in current critical investigations of a nonanthropoentric universe.

Climate Change, Cattle, And The Challenge Of Sustainability In A Telecoupled System In Africa, Tara S. Easter, Alexander K. Killion, Neil H. Carter

Ecology, Evolution, and Behavior

Information, energy, and materials are flowing over greater distances than in the past, changing the structure and feedbacks within and across coupled human and natural systems worldwide. The telecoupling framework was recently developed to understand the feedbacks and multidirectional flows characterizing social and environmental interactions between distant systems. We extend the application of the telecoupling framework to illustrate how flows in beef affect and are affected by social-ecological processes occurring between distant systems in Africa, and how those dynamics will likely change over the next few decades because of climate-induced shifts in a major bovine disease, trypanosomosis. The disease is …

Watered Down: The Challenges Of Managing Water Resources In Montana, Beau E. Baker

Graduate Student Theses, Dissertations, & Professional Papers

Like much of the American West, Montana sits in the cross hairs of climate change. State drought resiliency projects and cooperative watershed management are on the rise in the face of decreased snowpack, early runoff, precipitation variability and lower seasonal stream flows. Population growth, land use practices, recreation and tourism all contribute to pressures on state water supplies.

Montana is faced with the arrival of invasive species that threaten the ecological health of its lakes, rivers and streams. State budget constraints and depressed agency capacity are hurting our ability to fend off these threats. There’s a lack of public education …

Transitioning Montana To A Renewable Energy Future: The Social And Economic Impacts, Jacqueline O. Sussman

Montana is home to the second-largest coal-fired power plant in the West, the Colstrip Generating Station. The value and demand for coal both domestically and globally is quickly diminishing, while the renewable energy industries of wind and solar are booming. As utilities in the Northwest transition their investments from coal to renewable energy, Montana faces a critical decision on the future of its energy system that will impact the lives of generations of Montanans to come.

This five-part report aims to aid in the discussion and decision-making process by reviewing the most up-to-date economic data on renewable energy; discussing the …

Implementing Climate Change Research At Universities: Barriers, Potential And Actions, Walter Leal Filho, Edward A. Morgan, Eric S. Godoy, Ulisses M. Azeiteiro, Paula Bacelar-Nicolau, Lucas Veiga Ávila, Claudia Mac-Lean, Jean Hugé

Faculty Publications - Philosophy

Many universities around the world have been active centres of climate change research. However, there are a number of barriers to climate change research, stemming both from the nature of the research and the structure of institutions. This paper offers an overview of the barriers which hinder the handling of matters related to climate change at institutions of higher education (IHEs), and reports on an empirical study to investigate these barriers using a global survey of higher education institutions. It concludes by proposing some steps which could be followed with a view to making climate change more present and effective …

Indigenous-Led Resistance To Environmental Destruction: Methods Of Anishinaabe Land Defense Against Enbridge's Line 3, Charlotte Degener Hughes

Pitzer Senior Theses

Enbridge has proposed the Line 3 “Replacement” Project, a new pipeline project taking a new route strait through Anishinaabe treaty territory in what is known as northern Minnesota. In the middle of the regulation process, the future remains unclear of how the State of Minnesota will move forward with the permitting process, but Anishinaabe communities, a range of non-profit organizations, and local landowners remain firmly against the line. Rooted in varied frameworks of Native sovereignty, the land, and Indigenous feminism, Anishinaabe communities lead the resistance against a product of ongoing settler colonialism, racial capitalism, and environmental racism. This thesis contextualizes …

Waste Reduction In Public School Cafeterias Through Sorting And Diversion: An Analysis Of Three Southern Maine Schools, Jeremy P. Ravenelle

Honors Theses

Solid waste is a serious environmental problem in the modern world. School cafeterias are one source of food and packaging waste that must be dealt with. Reducing the amount of cafeteria waste disposed of as trash through source reduction, recycling, and composting can not only improve environmental outcomes but also teach students about sustainability and save schools money. Social practice theory provides some factors that may be helpful to examine school cafeteria waste reduction programs. Using these factors, this thesis first examines school waste reduction programs in articles from academic databases, and then in three case study elementary schools in …

The Identification And Application Of Generalizable Spatial Patterns Of Human-Wildlife Conflict, Vivian F. Hawkinson

Honors Theses

Many human-wildlife conflict studies focus on one location or one individual species or taxonomic group; fewer comparative studies analyze patterns of conflict across species and regions. As a result, numerous studies report similar conclusions across diverse cases of human-wildlife conflict. I found 133 scholarly articles published between 1975 and 2017 referencing distance from a protected area boundary as a variable associated with human-wildlife conflict. I identified three generalizable patterns of human-wildlife conflict that appear across taxonomic groups and geographic locations. The family Felidae had the highest maximum average conflict distance and furthest distance from a protected area that conflict was …

Closing The Loop: Exploring Ikea’S Transition To The Circular Economy, Alexandra Seidel

Pomona Senior Theses

Inspired by the way nature cycles waste in an ecosystem, the circular economy was developed as an alternative to the linear take-make-dispose model and designed to decouple economic growth from resource use. After developing a framework for what it means to be a business pursuing circularity, this thesis examines six different companies to explore the tension between the strategies and business models in theory and what business are implementing in practice today. This exploration continues with an in-depth analysis of the circular success of IKEA, finding that the gains from the circular economy for a large corporation are found within …

Effects Of Variable Density Thinning On Spatial Patterns Of Overstory Trees In Mt. Hood National Forest, Emma Huston

Environmental Science and Management Professional Master's Project Reports

Variable density thinning (VDT) is a method of restoration thinning that attempts to increase ecosystem resilience and spatial heterogeneity in forest stands to more closely resemble mosaic-like patterns characteristic of late-successional forests, which consist of clusters of multiple trees, individual trees, and gaps. This study examines the spatial patterning of overstory trees resulting from VDT of conifer forests in Mt. Hood National Forest in the western Cascade Mountains and compares these patterns with reference conditions. Stem maps were created from field surveys of study plots within one mature stand and six thinned stands designated as Late-Successional Reserve (LSR) with varying …

Long-Term Managed Flooding To Control Invasive Phalaris Arundinacea L. And Help Restore Native Vegetation In An Urban Palustrine Wetlands Ecosystem, Robert P. Lascheck

Environmental Science and Management Professional Master's Project Reports

We sought to determine the effects of 13 years of hydrologic management on the wetland plant community in Smith and Bybee Wetlands Natural Area (SBW), an 809 ha palustrine wetland complex in north Portland, Oregon. Previous management efforts resulted in an altered hydrologic regime; historically high water levels in spring and low water levels in fall were replaced by persistent water levels with minimal annual variations. A water control structure was installed in 2003 to better approximate historic seasonal hydrologic changes to reduce invasive Phalaris arundinacea (reed canarygrass) cover and promote native wetland vegetation growth. Vegetation monitoring has been carried …

Sustainability-Efficiency Paradox: The Efficacy Of State Energy Plans In Building A More Sustainable Energy Future, Austin Zimmerman

Pitzer Senior Theses

State energy plans are created at the request of a sitting governor or State Legislature in order to provide guidance set goals for the state’s energy sector. These plans will be critical indicators of energy trends such as the future market share of coal, natural gas, and renewables. If the future of energy in the United States is to be remotely sustainable, low-carbon policies must headline state plans. The strength of a state’s energy plan in terms of sustainability is directly related to that state’s willingness to prioritize and commit to incorporating energy sources that produce negligible carbon emissions. Questions …

Wine About It: How Climate Change Is Affecting International Wine Markets, Krysta Suzanne Gingue

Honors Theses and Capstones

The purpose of this study is to understand the social context surrounding wine and how consumers and producers will act within the existing market structures to physical changes to wine due to climate change. After defining the socially embedded structure of market values, this paper questions how they will survive with the visible and invisible changes being made to wines and wine regions. Through various case studies the paper uncovers climate events happening across the world and how they will potentially change the economic landscape of wine markets. The different lenses required to understand the market lead to competing conclusions. …

Assessing Effort Shifts And Familial Succession In Oregon’S Nearshore Fisheries, Bryn Ellen Hudson

Environmental Science and Management Professional Master's Project Reports

Since the industrial revolution, natural resource systems have rapidly modernized and globalized. Commercial fishing industries have expanded and optimized resource extraction but have often times exceeded sustainable levels of harvest. In the Pacific Northwestern United States, the commercial fishing industry is one of particular economic and cultural importance. Due to reduced yield of many native fish stocks, marine reserves have been implemented in Oregon’s nearshore waters in an effort to conserve biodiversity. While spatial closures of marine reserves seek to preserve and stabilize Oregon’s ocean ecosystems, adverse socioeconomic implications are inevitably created when profitable waters are set aside. A main …

Evaluating Long-Term Trends In Vegetation And Management Intensity, Tallgrass Prairie National Preserve 1995–2014, Sherry A. Leis, Lloyd W. Morrison

United States National Park Service: Publications

Abstract

Inventory and Monitoring Networks of the National Park Service are charged with collecting and reporting data related to the status and trends of key natural resources. We have analyzed a suite of grazing data from 1995- 2016, fire history data from 1998-2015, and vegetation community data from 2002-2014 to better understand trends as they relate to management strategies at the preserve over time. We found that cattle stocking rates declined and fires became less frequent over the latter half of the record. Similarly, bare ground declined, woody species increased slightly, and the floristic quality index was relatively stable with …

The Trade-Security Nexus And U.S. Policy Making In Critical Minerals, Yujia He

Patterson School of Diplomacy and International Commerce Faculty Publications

The United States increasingly relies on import to meet its demand for critical minerals. Using the case of rare earth elements (REEs), this paper analyzes the conditions and the strategies for the U.S. government to address import dependence. The paper finds that market factors, including the lack of comparable and sufficient substitutes and recycling, the high ratio of import relative to consumption, the high concentration of import supply by country, and regulations from the major supplier country, were insufficient to prompt intervention. Significant policy action only occurs when changing circumstances turn import dependence into perceived national security threats to the …

Using Contingent Valuation To Measure The Economic Impact Of Climate Change On Hiker Recreation During New England Peak Foliage, Marina J. Bowie

Honors Theses and Capstones

This paper seeks to define and develop an economic tool for measuring willingness to pay for hiking recreation in the face of climate change in New England during the peak foliage season. Potential climate change impacts to New England are defined, along with relevant economic tools for measuring the market value of non-marketed goods. Ultimately, contingent valuation is chosen as the most viable option, and a survey is developed, pretested, and ready for implementation at the trailhead of Mt. Major in New Hampshire.
