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 …

Honors Papers

This research is a case-based comparative analysis between bottle bill campaigns and policies in four different U.S. states in order to analyze the determining and preventative variables in the passage of bottle bills. 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” …

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, …

An Introductory Examination Of Worldviews And Why They Matter For Environmental And Sustainability Studies, Loren B. Byrne

Arts & Sciences Faculty Publications

A worldview is a complex cognitive and affective lens through which a person sees and interprets the world, including human-environment relationships. Examining worldviews is relevant to environmental and sustainability studies, in part, because they influence a person’s environmentally related decisions and divergent worldviews create conflict about environmental problems and solutions. Using physical glasses that make an abstract concept more concrete, the activity described in this chapter introduces students to worldviews and their links to environmental and sustainability issues through informal, open-ended, exploratory dialogue, catalyzed by the examination of four individuals’ hypothetical worldviews as playful case studies. The activity’s goal is …
