Shifting Baselines Of Iconic Marine Species In The Caribbean, Samantha Lovell

Honors Theses

As the degradation of Caribbean coral reefs occurs, memory of past states is lost so the degraded status is used as a standard in management, a phenomenon known as “shifting baselines.” To set restoration targets, marine historical ecology studies are helpful to document baselines of species and understand the past productivity of ecosystems. In this study, I examine the historical ecology of the islands Barbuda, Curaçao, and Montserrat. I analyzed archival materials, including historical maps and other documents from the islands to identify previously abundant or iconic species and understand historical changes. From the archival resources I identified 30 places …

The Impact Of Endocrine-Disrupting Chemicals On Wildlife Conservation, Eda Reed

Honors Theses

Endocrine-disrupting chemicals (EDCs), such as those from plastics and pesticides, have been hypothesized to affect wildlife populations. According to the U.S. National Institute of Environmental Health Sciences, EDCs ‘are chemicals that may interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife.’ A growing number of studies suggest wildlife are being exposed to EDCs, but how EDCs affect wildlife health and wildlife conservation is less well-understood. Through scientific literature analysis and a survey of wildlife conservationists and practitioners, this study aims to determine the current state of knowledge and data …

The Influence Of Urban Development Dynamics On Community Resilience Practice In New York City After Superstorm Sandy: Experiences From The Lower East Side And The Rockaways, Leigh Graham, Wim Debucquoy, Isabelle Anguelovski

Publications and Research

While (urban) resilience has become an increasingly popular concept, especially in the areas of disaster risk reduction (DRR) and climate change adaptation (CCA), it is often still used as an abstract metaphor, with much debate centered on definitions, differences in approaches, and epistemological consider- ations. Empirical studies examining how community-based organizations (CBOs) “practice” resilience on the ground and what enables these CBOs to organize and mobilize around resilience are lacking. Moreover, in the growing context of competitive and entrepreneurial urbanism and conflicting priorities about urban (re)development, it is unclear how urban development dynamics influence community- based resilience actions. Through empirical …

Climate And Bark Beetle Effects On Forest Productivity — Linking Dendroecology With Forest Landscape Modeling, Alec M. Kretchun, E. Louise Loudermilk, Robert M. Scheller, Matthew Hurteau, Soumaya Belmecher

Environmental Science and Management Faculty Publications and Presentations

In forested systems throughout the world, climate influences tree growth and aboveground net primary productivity (ANPP). The effects of extreme climate events (i.e., drought) on ANPP can be compounded by biotic factors (e.g., insect outbreaks). Understanding the contribution of each of these influences on growth requires information at multiple spatial scales and is essential for understanding regional forest response to changing climate. The mixed conifer forests of the Lake Tahoe Basin, California and Nevada, provide an opportunity to analyze biotic and abiotic influences on ANPP. Our objective was to evaluate the influence of moisture stress (climatic water deficit, CWD) and …

Little Rebecca, Rebecca Collins

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Santiago de Compostela, a city in Galicia, Spain, has been said since the 8th century to hold the remains of St. James, an apostle and the patron saint of Spain. Old walking routes, still in use, fork all throughout the European continent toward this singular destination, with the collective label of the “Way of St. James,” (the Camino de Santiago in Spanish, Le Chemin du St. Jacques in French). For nine months of this past year, the Camino de Santiago and the study of pilgrimage was my singular destination as well. I studied the history of pilgrimage, European pilgrimage literature, …

As a result, understanding agricultural sustainability has become a global issue. Assessment is a first step in benchmarking and tracking agricultural sustainability and …

Corporate Social Responsibility/Sustainability Reporting Among The Fortune Global 250: Greenwashing Or Green Supply Chain?, John K. Lewis

Faculty and Staff - Articles & Papers

The sustainability reporting efforts of MNCs who are members of the Fortune Global 250 (FG250) was investigated. The focus was on sustainability reporting by MNCs of supply chain impacts. The reporting of FG250 MNCs was examined to determine if greenwashing was occurring or whether MNCs had committed to operating a green supply chain. A mixed methodology was used consisting of quantitative analysis of twenty-five MNC CSR/sustainability reports which were randomly selected from the FG250 listing. Qualitative analysis using content analysis was also conducted on the reports. Both methodologies concentrated on the sustainability reporting of the selected MNCs in regard to …

The Ethical Issues Of Dumping Electronic Waste In India, Krista E. Dawson

Augustana Center for the Study of Ethics Essay Contest

Electronic waste, also referred to as “e-waste,” is all waste made from electronic products such as computers, mobile phones, digital music players, refrigerators, washing machines, and TV’s (Pinto, 2008). There is e-waste produced in the manufacturing process as well as the final disposal of the product. Although developed countries consume most electronics, it is increasingly common for countries that are still developing to possess electronic goods (Larrdis, 2011). Use of technology and connection to worldwide networking is a huge step for the progress of these countries, but having gained a “part” of the developed world without the associated infrastructure to …

The Roles Of Introduced Eucalyptus In The Conservation And Expansion Of Ethiopian Orthodox Church Forests In The Northern Ethiopian Highlands, Janice Liang

Honors Theses

Species of the genus Eucalyptus (common name eucalyptus) are widely planted all across Ethiopia – including on large areas of land previously allocated to food production. In recent decades eucalyptus has also increasingly been planted on lands around and within “church forests,” sacred groves of old-aged Afromontane trees surrounding Ethiopian Orthodox Tewahido churches. These revered holy sites have long been recognized for their cultural values and also for their ecosystem services – including their potential to support species conservation and restoration, as church forests are some of the only remaining sanctuaries for many of Ethiopia’s indigenous and endemic plant and …

What A Waste: Segregation And Sanitation In Brooklyn, New York In The Post-Wwii Era, Amanda T. Chang

Pitzer Senior Theses

Through studying the intersections of sanitation and segregation in Brooklyn, New York in the post-WWII era, this thesis reveals a web of willful white negligence that constructed a narrative that supports continued environmental injustices towards black Americans. As a result of housing discrimination, the lack of sanitation, and the political and social climate of the 1950s, black neighborhoods in Brooklyn became dirtier with abandoned garbage. Institutional anti-black racism not only permitted and supported the degradation of black neighborhoods, but also created an association between black Americans and trash. In the present day, this narrative not only leads to the increased …

Contributions Of Glacier Melting To The Upper Watershed Of The Pita River, Ecuador, Teresa Munoz Martinez

Dissertations, Master's Theses and Master's Reports

Evidence suggests that a changing global climate is accelerating glacial retreat around the world. However, there are not many studies that help to understand the influence of climate change on glaciers in the tropical Andes. In many Andean countries, populations use the water that come from the high altitude mountains, especially mountains that are ice covered. Glacial reduction minimizes water resource availability. This report focuses on better understanding the relationship between glacier meltwater, surface water runoff, and the groundwater flowing into and under the Pita River upper watershed, which crosses the base of the northeast foothills of the Cotopaxi volcano. …

Crowded: Population Pressures In San Francisco Bay Area National Park Service Properties, Caroline R. Ebinger

Scripps Senior Theses

This paper hopes to analyze the intersection between diversity and numbers of visitors and landscape preservation in the National Park Service. Current scholarship addresses either diversity in the Park System or carrying capacity and human population pressures. However, both are critical issues facing the National Park Service in the 21^st century, and looking at the issues in isolation means missing a key interaction and potentially working to solve one problem that in turn amplifies another. Here, diversity of park-goers and preservation priorities will be addressed together, each as part of the other.

Shipbreaking In Bangladesh: Perspectives From Industrial Ecology, Political Ecology And Environmental Policy, S.M. Mizanur Rahman

Dissertations, Master's Theses and Master's Reports

The international shipbreaking industry connects developed and developing countries through the spatial and temporal flow of resources, both transported by the ships and by the recycling of the ships themselves. Much of the research on this industry to date focuses on a natural science perspective, particularly related to local pollution when the ships are recycled. However, many products for the public (such as documentaries and magazine articles) focus on the workers who dismantle these ships, often with minimal protection; the appalling images of shipbreaking yard workers and their polluted surrounds have garnered immense global attention and calls for better regulations. …

3d Tool Evaluation And Workflow For An Ecological Approach To Visualizing Ancient Socio-Environmental Landscapes: A Case Study From Copan, Honduras, Heather Richards-Rissetto, Shona Sanford-Long, Jack Kerby-Miller

Department of Anthropology: Faculty Publications

Architectural reconstructions are the centerpieces of ancient landscape visualization. When present, vegetation is relegated to the background, resulting in underutilized plant data—an integral data source for archaeological interpretation—thus limiting the capacity to take advantage of 3D visualization for studying ancient socio-environmental dynamics. Our long-term objective is to develop methods of 3D landscape visualization that have value for examining changes in land use and settlement patterns. To begin to work toward this objective, we have (1) identified 3D tools and techniques for vegetation modeling and landscape visualization, (2) evaluated the pros and cons of these tools, (3) investigated biological and ecological …

Additionally, this study compares what ways these types of legislation are ultimately effective or ineffective in meeting economic, environmental, and social goals under the framework of Triple Bottom Line Sustainability. These four case study states (OR, ME, MA, and WA) have been selected to exemplify several public, private, and mixed systems that display varying outcomes in participation in the program and impacts on litter and local economies. …

Life-Cycle Cost Analysis Of Nutrient Reduction Technologies Employed In Municipal Wastewater Treatment, Colin Barrett Brown

Honors Papers

Eutrophication presents a serious threat to America's aquatic ecosystems, negatively impacting both the aquatic life and the communities dependent on these bodies of water. Reducing nutrient inflow of nitrogen and phosphorus into waterways from point and non-point sources is critical in reversing the environmental degradation caused by eutrophication. Municipal wastewater treatment plants are one of the primary point sources of nutrient-rich effluent, and as such, implementing nutrient reduction strategies within the treatment process is an impactful step towards mitigating eutrophication. Grey infrastructure technologies that use mechanical or chemical treatment have historically been used for wastewater nutrient reduction. However, constructed wetlands …

Hiker Trash And Trail Dogs: An Ethnographic Inquiry Into Human Nature In The Trail Space, Jody A. Chinchen

All Master's Theses

In the face of declining trail maintenance budgets and increasing recreational use, we must develop a critical understanding of trail culture, including the motivations, perspectives, and experiences of various users and how they intersect with one another. Trail use on National Scenic Trails (NSTs) may represent a deeper symbolic yearning to seek out meaningful connections with nature, self, and community. This study seeks to understand: (1) How trails are built and paved with meaning, (2) how trails foster and sustain social, symbolic, and material landscapes, through performance of work and leisure; and (3) the relationship between the National Wilderness Preservation …

Sustainable Safari Practices: Proximity To Wildlife, Educational Intervention And The Quality Of Experience, Ryan Devine Tarver

All Master's Theses

This research examines the perceived quality of experience for safari tourists in relation to wildlife viewing proximities and the potential of educational interventions as a management strategy to mitigate adverse impacts of safari participant crowding. Crowding emanates from the safari tourist preferences to obtain close proximity to animals, particularly large mammals. Recognizing these preferences and associated impacts to animal behavior defined in previous research, we develop and deliver a survey instrument designed to measure the perceived quality of experience of the safari tourist while controlling for the viewing proximity variable. The survey instrument involves responding to stock photos selected to …

Identifying Plant Functional Traits To Assist Ecological Intervention In A Drying Landscape, Ana Luiza Muler

Theses: Doctorates and Masters

Mediterranean-type ecosystems (MTEs) are among the most vulnerable to land use and climate change and many attempts are in place to restore these ecosystems. Therefore, it is necessary to assess differences in plants’ ability to withstand water-stress, including biotic interactions. Such knowledge helps us understand community assembly, which is crucial for ecological intervention. This study involved: (1) reviewing the literature on traits that can differentiate functional types; (2) adapting the methodology to measure leaf water potential at turgor loss point (πtlp) for small-leaved species; (3) using these traits to quickly identify water-use strategies of adult …

A Sustainability-Based Project Selection Algorithm: Socio-Technical-Economic Project Selection (Steps) Algorithm, Bharathi Bhattu

Dissertations, Master's Theses and Master's Reports

Multi-dimensional aspects play a vital role in the task of project-decision making. Environmental effects are to be considered in addition to other technical and non-technical aspects in order to avoid undue environmental damage. This current work introduces a new decision-making algorithm (Socio-Technical-Economic Project Selection or STEPS) that is demonstrated with the use of RCA (recycled concrete aggregate) as riprap for slope stabilization and erosion control which leaches chemical arsenic when in contact with water. Arsenic has long been recognized for its lethal properties. The main intention of introducing this new algorithm is to use sustainability concepts of social, technical, and …

Disasters Are Not, They Become: An Understanding Of Social Vulnerability In The United States Gulf Coast With Respect To Hurricanes, Katherine Franklin

Scripps Senior Theses

Scientific literature is concerned with the impact that climate change will have on natural disasters in the near future. These events disrupt our daily lives and can cause damage that may never be repaired. Merging science and social science, the study of vulnerability looks at how human systems will be impacted by these natural disasters. In the United States, hurricanes in the Gulf Coast are projected to increase in intensity as well as have an increased capacity for damage with a rise in sea level. Therefore, it is important to understand who is systematically vulnerable to these impacts of natural …

The Philosophy Of Ecology In John Steinbeck's The Grapes Of Wrath, Stephanie A. Steinbrecher

Scripps Senior Theses

This thesis explores the possibilities for ecocritical study in fiction through John Steinbeck’s 1939 novel The Grapes of Wrath. Major ecocritical interpretation has yet to gain much traction in novels; by focusing on human nature, this form’s “anthropocentric” posture seems itself to be antithetical to ecocritical efforts, which aim to unseat humans as the center of the moral universe. However, by analyzing The Grapes of Wrath’s formal, narratorial, and thematic valences, I argue that principles of social justice concurrently imply environmental justice in the philosophical currents of the text. Tenets of deep ecology and Aldo Leopold’s “land ethic” …

Dismantling Structural Inequality In The Inland Empire: Rebuilding Community From The Ground Up At Huerta Del Valle Garden, Jennifer E. Reyff

Scripps Senior Theses

This thesis provides an analytical case study of Huerta del Valle Community Garden as a successful model of redefining social capital through not only providing healthy, affordable, high quality produce to a community subjected to the disproportionate consequences of systemic inequality, but also in incorporating a food justice education framework to underlie all development at the garden. Located in the city of Ontario, Southern California – the heart of the Inland Empire, known for its prominence within the nation’s goods movement industry and its landscape of sprawling warehouses – local residents face high rates of poverty, obesity, and a lack …

Increasing Energy Efficiency In Existing Residential Buildings: A Case Study Of The Community Home Energy Retrofit Project (Cherp), Jenna Perelman

Scripps Senior Theses

This thesis uses a case study of the Community Home Energy Retrofit Project (CHERP) and it analyzes the larger statewide effort in California to increase energy efficiency in existing residential buildings to reduce greenhouse gas emissions. CHERP’s primary strategy is to embed itself into a community, educate residents on the multiple benefits of energy efficiency, and inspire them to take energy-saving actions in their own homes. It then builds its own community by connecting like-minded individuals together and provides an opportunity for them to exercise their political agency. This thesis analyzes CHERP’s effort in the context of the political, social, …

Conservation Genetics On The Frontline, Kenneth W. Rand

Graduate Student Theses, Dissertations, & Professional Papers
