Piecemeal Reform Of Trade And Environmental Policy When Consumption Also Pollutes, Mark R. Metcalfe, John C. Beghin

Department of Agricultural Economics: Faculty Publications

We incorporate endogenous (price-responsive) consumption pollution into a dual trade model to assess welfare effects of coordinated trade and environmental piecemeal reform in a small, open and distorted economy. Pollution is generated by production and consumption. Producers control the level of pollution and face incentives to abate both types of pollution. We identify sufficient conditions for welfare-improving reforms of trade and environmental policies. An additional domestic environmental policy instrument must be imposed on exportables because of their supply response to foreign environmental taxes.

The Perceptions, Knowledge, Benefits And Barriers Of Hispanics Regarding The Dietary Guidelines For Americans, Luisyana De Amor Gamboa

Theses and Dissertations--Nutrition and Food Systems

Background: Hispanics are the largest minority group in the U.S. and by the year 2060 the number of Hispanics is projected to double. They are disproportionately affected by obesity and chronic diseases which translate into decreased quality of life, loss of work opportunities and perceptions of injustice for the Hispanic population. The Dietary Guidelines (DG) provide information to help Americans make healthy food and physical activity choices and if followed can be a means of reducing the health disparity gap. However, culturally relevant recommendations specific to Hispanics’ health and nutritional habits are often lacking. The purpose of this study was …

Abundance, Density, And Opinions About Columbian Black-Tailed Deer, Whidbey Island, Washington, Robert P. Wingard

Graduate Student Theses, Dissertations, & Professional Papers

Obtaining reliable knowledge is the first step towards properly managing wildlife species. Columbian black-tailed deer (Odocoileus hemionus columbianus) on Whidbey Island, Washington have not been the subject of study, and little is known about the population, or the opinion of resident’s of Whidbey Island towards the deer population. However, wildlife managers suggest deer on the island may be overabundant or over social carrying capacity. Given the lack of empirical knowledge about the deer population or human opinions towards deer on Whidbey Island, I designed research to determine the abundance and density of Columbian black-tailed deer on Whidbey Island, …

Off The Court, Onto The Farm, Arza E. Hammond

Graduate Student Theses, Dissertations, & Professional Papers

This work contains two separate but connected stories about developing a relationship with something larger than myself. Reaching the end of my basketball career forced me to examine my relationship with the great game of basketball and my role in it. After ending my hoops career, I spent a summer working and living on a small, organic farm. The lessons I learned from the game helped me to develop a meaningful relationship with the farm and to find a reciprocal role with the land I lived and worked on.

School Gardens: Cultivating A Child’S Nutritional Habits, Environmental Knowledge, And Sustainability Practices, Jeffrey Meltzer

Honors Theses

School gardens have existed since the late nineteenth century and today are becoming increasingly popular in many parts of the world, including where I studied in Maine and Australia (AUS). Multiple organizations support school gardens in Maine, including the Maine School Garden Network, which has over 125 registered school gardens. In AUS, the Stephanie Alexander Kitchen Garden Foundation primarily supports the school garden movement and has over 800 registered school gardens. While many researchers have studied school gardens, few have compared two countries, focused on environmental sustainability, or investigated Maine in particular. This thesis combines information from literature reviews, and …

A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz

Graduate Student Theses, Dissertations, & Professional Papers

Chile's state designated protected areas are reported to show representation bias and to be unable to meet conservation goals. Private protected areas are considered an important tool to resolve these issues, which has led to support for increasing the role of private protected areas in Chile and creating an integrated public-private protected area network. But the validity of the capacity of private protected areas to fix Chile's state protected area network bias, and the advantage of creating an integrated protected area network, have not been assessed. This study uses the most recent data on Chile's state, private, and international protected …

Behavioral Response Of Pacific Lamprey (Entosphenus Tridentatus) To Predator Odors, Laurie L. Porter

All Master's Theses

Pacific lamprey (Entosphenus tridentatus), a species facing serious threats to their existence, experience a number of challenges in reaching their desired spawning grounds during the adult migratory phase, and predators are suspected to be one of these challenges. Understanding if Pacific lamprey respond to predator odorants may provide a management tool for use in conjunction with attractants in guiding lamprey to suitable spawning habitat and deterring them from poor habitat. Previous research has failed to explore Pacific lamprey response to predator odorants, although much research exists on attractant odorants. In our study, we tested Pacific lamprey response to …

Provisioning And Its Effects On The Social Interactions Of Tibetan Macaques (Macaca Thibetana) At Mt. Huangshan, China, Brianna I. Schnepel

All Master's Theses

The dispersal patterns of food resources has a significant effect on the composition of primate groups and social interactions within those groups. Humans often alter the dispersal of food. Non-humans often use affiliative behaviors to elicit tolerance or support from other group members. I investigated whether provisioned food resources alter the social interactions and group dynamics of Macaca thibetana. All-occurrence sampling and scan sampling were used for data recorded by camera traps. Trail-cameras were placed at six locations that contain natural and human food resources and recorded 60-second videos. Social behavior and proximity of the monkeys were recorded. I …

Carbon Storage And Preservation In Seagrass Meadows, Mohammad Rozaimi Jamaludin

Theses: Doctorates and Masters

Seagrass meadows are important ‘Blue Carbon’ sinks but many questions remain unaddressed in regards to the organic carbon (OC) sequestration capacity and processes leading to retention and persistence of OC in seagrass sediments. The research summarised in this dissertation examined 37 sediment cores from twelve Australian seagrass meadows (Posidonia australis and Halophila ovalis) in order to improve our understanding of OC storage and preservation in seagrass sediments. The research: quantified the OC storage in seagrass meadows and the reduction in stores after ecosystem degradation; the rates of OC accumulation; the roles of species composition and the depositional nature …

A Basic Guide For Empirical Environmental Social Science, Michael Cox

Dartmouth Scholarship

In this paper, I address a gap in the literature on environmental social science by providing a basic rubric for the conduct of empirical research in this interdisciplinary field. Current literature displays a healthy diversity of methods and techniques, but this has also been accompanied by a lack of consistency in the way in which research in this area is done. In part this can be seen as resulting from a lack in supporting texts that would provide a basis for this consistency. Although relevant methods texts do exist, these are not written with this type of research explicitly in …

A Critical Examination Of Private Conservation Areas On Campesino Community Lands In Peru, Megan Barnhart

Graduate Student Theses, Dissertations, & Professional Papers

Community-owned private reserves are emerging around the world as an alternative to government-run resource management and as a way to more directly involve citizens as stewards of their local natural resources. Despite their recent proliferation globally, voluntary efforts by communities to include their land in protected area systems, and the motivations and expectations of their legal recognition remain largely unknown. This thesis examines community-owned private conservation areas in Northern Peru locally known as Áreas de Conservación Privadas (ACPs) which are voluntary and legally recognized by the Peruvian State. The study investigates the rationales and outcomes of the application of ACPs …

Approximation Of Fire-Return Intervals With Point Samples In The Southern Range Of The Coast Redwood Forest, California, Usa, Gregory Jones, Will Russell

Faculty Publications, Environmental Studies

A legacy of past fires is evident in the form of blackened basal hollows found throughout the southern range of the coast redwood (Sequoia sempervirens [D. Don] Endl.) forest.  A deeper look reveals cambial scars dating back centuries, telling a story of low- to moderate-intensity fires that burned periodically across California’s Central Coast bioregion.  While attempts have been made to reconstruct the fire history of this forest type, estimates of the fire-return interval vary widely, and the relationship of the fire-return interval to varying cultural influences is not fully understood.  We analyzed 373 fire scars from 70 cross-sections removed from …

Dispersal: A Multidisciplinary Investigation Of Plant Life, Alexandra E. Arzt

Theses and Dissertations

Using plants as a basis for exploring the interstices between the human and nonhuman, this thesis investigates ideas of awareness, intelligence, deep time, animism, and the fluctuating human perception of the agency of Nature. It outlines environmental art practices since the 1950s involving vegetal life. In addition, the paper provides a critical analysis of plant perception of Jakob von Uexküll’s work and theories of vital materialism and “critical plant studies” while noting recent studies in plant neurobiology. In my work, plants become active participants via their movement, seeding, and smell. This study takes the form of imitation, purposeful symbiosis, anthropomorphism, …

Expanding Eco-Visualization: Sculpting Corn Production, Jennifer E. Figg

Theses and Dissertations

This dissertation expands upon the definition of eco-visualization artwork. EV was originally defined in 2006 by Tiffany Holmes as a way to display the real time consumption statistics of key environmental resources for the goal of promoting ecological literacy. I assert that the final forms of EV artworks are not necessarily dependent on technology, and can differ in terms of media used, in that they can be sculptural, video-based, or static two-dimensional forms that communicate interpreted environmental information. There are two main categories of EV: one that is predominantly screen-based and another that employs a variety of modes of representation …

Weed Women, All Night Vigils, And The Secret Life Of Plants: Negotiated Epistemologies Of Ethnogynecological Plant Knowledge In American History, Claudia Jeanne Ford

Antioch University Dissertations & Theses

This dissertation critiques the discourse of traditional ecological knowledge described as embedded in indigenous peoples' longevity in location, for the purpose of understanding the embodiment of ecological knowledge in culture. The aim of this research is to examine the historical and epistemic complexity of traditional ecological knowledge that may be both established from the length of time people reside in a specific ecosystem and constitutive of negotiations between and among different cultures. I choose the specific case of the negotiation of plant knowledge for women's reproductive health among Native, African, and European groups as those negotiations unfolded on the American …

Ramapough/Ford The Impact And Survival Of An Indigenous Community In The Shadow Of Ford Motor Company’S Toxic Legacy, Chuck Stead

Antioch University Dissertations & Theses

The purpose of this study was to examine the history of the Ford Motor Company’s impact upon the Ramapo Watershed of New York and New Jersey, as well as upon the Ramapough Munsi Nation, an indigenous population living there. In a 25 year span the automaker produced a record number of vehicles and dumped a massive amount of lead paint, leaving behind a toxic legacy that continues to plaque the area and its residents. The Ramapough people are not unlike many native nations living in the United States who have experienced industrial excess. This study examines the mindset that allows …

Coastal Environmental Policies And Water: Environmental Values In Ghana And Senegal, Molly R. Loftus

CMC Senior Theses

This thesis provides a comparative analysis of the environmental values present in Ghana’s and Senegal’s coastal regions, and the implications that those have for the surrounding environment. The countries approaches to urban farming, mining and oil and gas extraction, fishing, marine debris and municipal waste management are assessed in order to reach a greater understanding of these environmental issues. In undertaking this thesis, I attempted to draw a correlation between the handling of these issues and how people perceive their environment. Through the comparison of environmental degradation and the level of effort to achieve a more sustainable developmental framework in …

River Health In Puyo, Ecuador The Use Of Macroinvertebrates As Bioindicators Of Water Quality And Alternatives To Chlorine For Whitening Clothes In The Puyo River Watershed, Allison Rowe

Independent Study Project (ISP) Collection

Fresh water is an important resource in Puyo, Ecuador, a city named after the Kichwa word for ‘cloudy’ in reference to its overcast weather. However, the Puyo River watershed is the most contaminated in all of Pastaza Province. The objective of this investigation was first to evaluate the health of the Puyo River using macroinvertebrate analyses and measurements of chlorine concentrations, temperature, pH, turbidity, velocity, and flow rate. The second objective was to learn about practices used to whiten clothes in Puyo and perceptions of water quality in order to understand the magnitude of bleach pollution and the population’s awareness …

Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht

United States National Park Service: Publications

Executive Summary

Agate Fossil Beds National Monument is a 3,057-acre park located in western Nebraska. The unit is comprised of northern mixed-grass prairie vegetation, typical of the Northern Great Plains. Weather, fire, and grazing are generally considered to be the ecological drivers of prairie ecosystems and critical for prairie health. However, grazing has essentially been absent since the 1960s. In 2014, a Department of the Interior report explicitly listed the park as a high priority for bison restoration. This report evaluates the feasibility, management options, benefits, and challenges of restoring bison to Agate Fossil Beds National Monument.

Effects Of Extreme Climate Events On Tea (Camellia Sinensis) Functional Quality Validate Indigenous Farmer Knowledge And Sensory Preferences In Tropical China, Selena Ahmed, John Richard Stepp, Colin M. Orians, Timothy S. Griffin, Corene Matyas, Albert Robbat, Sean Cash, Dayuan Xue, Chunlin Long, Uchenna Unachukwu, Sarabeth Buckley, Edward J. Kennelly

Publications and Research

Climate change is impacting agro-ecosystems, crops, and farmer livelihoods in communities worldwide. While it is well understood that more frequent and intense climate events in many areas are resulting in a decline in crop yields, the impact on crop quality is less acknowledged, yet it is critical for food systems that benefit both farmers and consumers through high-quality products. This study examines tea (Camellia sinensis; Theaceae), the world’s most widely consumed beverage after water, as a study system to measure effects of seasonal precipitation variability on crop functional quality and associated farmer knowledge, preferences, and livelihoods. Sampling was conducted in …

Regulatory Capture, The Chesapeake Bay, And Hampton Roads: What's On Your Plate, Ronnie David Gannon

Institute for the Humanities Theses

The Chesapeake Bay and its 64,000 square mile watershed are both severely impacted from excessive amounts of nutrient pollution, which contributes to a growing presence of dead zones in the Bay. What causes nutrient pollution? What are dead zones? In addition, many of the Bay's commercially valuable species of marine life have been/ are overexploited to the point of collapse / verge of collapse. Despite all of these facts, management agencies continue to weakly enforce regulations. Why?

Not to mention, much of the Bay's marine life is unsustainably caught in the contaminated waters of Hampton Roads. How, and for what? …

Indigenous Knowledge And Science Unite To Reveal Spatial And Temporal Dimensions Of Distributional Shift In Wildlife Of Conservation Concern, Christina N. Service, Megan S. Adams, Kyle A. Artelle, Paul C. Paquet, Laura V. Grant, Chris T. Darimont

Population Distribution and Habitat Collection

Range shifts among wildlife can occur rapidly and impose cascading ecological, economic, and cultural consequences. However, occurrence data used to define distributional limits derived from scientific approaches are often outdated for wide ranging and elusive species, especially in remote environments. Accordingly, our aim was to amalgamate indigenous and western scientific evidence of grizzly bear (Ursus arctos horribilis) records and detail a potential range shift on the central coast of British Columbia, Canada. In addition, we test the hypothesis that data from each method yield similar results, as well as illustrate the complementary nature of this coupled approach. Combining information from …

"Nature Is Pushing One Way And People Are Pushing The Other": A Political Ecology Of Forest Transitions In Western Montgomery County, Pa, Megan Elizabeth Maccaroni

Environment and Sustainability Honors Papers

Forests in Southeastern Pennsylvania have been shaped by a number of anthropocentric factors over the past century, with many areas experiencing a recent trend towards forest recovery. Studies on forest dynamics have shown that most developed regions exhibit a forest transition, which begins when land is cleared for natural resource extraction (e.g., agriculture, forestry) during an early development stage. Then as a population grows and food production needs are met, rural peoples begin to migrate to the city, and a feeling of scarcity of trees develops that may lead to changes in land management attitudes, and many formerly deforested areas …

The Influence Of Topographic And Dynamic Cyclic Variables On The Distribution Of Small Cetaceans In A Shallow Coastal System, Marijke N. De Boer, Mark P. Simmonds, Peter J.H. Reijnders, Geert Aarts

Ecology Collection

The influence of topographic and temporal variables on cetacean distribution at a fine-scale is still poorly understood. To study the spatial and temporal distribution of harbour porpoise Phocoena phocoena and the poorly known Risso’s dolphin Grampus griseus we carried out land-based observations from Bardsey Island (Wales, UK) in summer (2001–2007). Using Kernel analysis and Generalized Additive Models it was shown that porpoises and Risso’s appeared to be linked to topographic and dynamic cyclic variables with both species using different core areas (dolphins to the West and porpoises to the East off Bardsey). Depth, slope and aspect and a low variation …

Assessing Perceived And Documented Crop Damage In A Tanzanian Village Impacted By Human-Elephant Conflict (Hec), Rebekah R. Hoffmeier-Karimi, Bruce A. Schulte

Biology Faculty Publications

In sub-Saharan Africa human-wildlife conflict (HWC) is a growing conservation issue and human-elephant conflict (HEC) is of special concern. Crop loss to wildlife comprises a main component of HWC. Deterrent methods for crop loss are numerous and such schemes could be more effective by an improved understanding of how farmers’ perceptions align with actual causes of crop loss. Our objective was to compare the perception by farmers of the causes and extent of crop damage to the measured crop damage in fields of maize (Zea mays) using different deterrent methods. We interviewed agriculturalists in the farming village of Miti Mirefu …
