The State Of Sachets: Ghana’S Private Sector Solution To A Public Infrastructure Problem,
2015
Pitzer College
The State Of Sachets: Ghana’S Private Sector Solution To A Public Infrastructure Problem, Robert J. Little
Pitzer Senior Theses
Known colloquially as “purewater”, sachet water has outcompeted all alternatives to Ghana’s unreliable government water infrastructure and serves as the cheap, portable, omnipresent solution for narrowing the safe water access gap. Each single-use sachet holds 500 ml of filtered potable water and is heat-sealed in a high-density polyethylene bag. Insufficient and often skeptical scholarship exists surrounding the state of sachet water in Ghana, and almost no research incorporates qualitative data into analysis and future recommendations. In the face of incomplete and decontextualized research on sachet water, this study aims to use qualitative data concerning Ghanaian viewpoints to showcase the …

Roots Versus Wells: Grassroots Activism Against Fracking In New York And California, Shannon J. Leap
Pitzer Senior Theses
The reliance upon and depletion of fossil fuels as an energy source puts pressure on individuals, communities, energy companies, and policy-makers. Hydraulic fracturing – known colloquially as fracking – as a method of drilling for oil and natural gas temporarily alleviates this pressure since it allows for the extraction previously inaccessible fossil fuels in shale rock deposits deep beneath the Earth’s surface. This has resulted in a nationwide “fracking boom,” which has come with its share of economic benefits. However, the process of fracking can be detrimental to human and environmental health. In reaction to the increasing development of this …
Insights Into Perspectives On Environmental Sustainability,

University of Kentucky
Insights Into Perspectives On Environmental Sustainability, Amber R. Shobe
Theses and Dissertations--Community & Leadership Development
As scientists become more aware of the imposing threats associated with climate change, university leaders are encouraged to become familiar with the principles of sustainability. Abundant research already supports the relevance of environmental sustainability in higher education; however, there exists a gap in the literature which investigates an understanding of environmental sustainability and the implementation of its practices. By examining colleges at the University of Kentucky, this study identifies organizational barriers to recognizing a thorough understanding of environmental sustainability at the departmental level. The results indicate that out of the eight colleges selected, two have no existing environmental sustainability programs …
The Use Of Improved Technology And Market-Based Incentives To Increase Forest Resource And Biodiversity Conservation In Rwanda,

University of Kentucky
The Use Of Improved Technology And Market-Based Incentives To Increase Forest Resource And Biodiversity Conservation In Rwanda, Kelly M. Rayens
Theses and Dissertations--Forestry and Natural Resources
This study evaluated the effectiveness of two distinct approaches to ecosystem conservation in Rwanda’s Nyungwe National Park: cookstove technology adoption and market-based policy instruments. A June 2014 survey of 250 households revealed that use of improved cookstove technology dramatically decreased fuelwood consumption for households in rural Rwanda, but that design, engineering and conflicting policy issues can hamper the widespread use of energy-efficient cooking technology. The second component of this research used the analytic hierarchy process (AHP) within a multi-criteria analysis (MCA) framework to explore the options for designing and implementing market-based instruments around the country’s conservation targets, particularly the highly …
Significance Evaluation Of The Forgotten Creek Site,

Central Washington University
Significance Evaluation Of The Forgotten Creek Site, Joy D. Ferry
All Master's Theses
Archaeological research has recognized the importance of montane environments in the subsistence and settlement strategies of pre-contact peoples. Yet little is understood about variation in the manner in which pre-contact peoples were using upland environments. In order to ascertain whether there is functional and/or technological variation between montane sites in comparable environmental settings, four lithic assemblages (45PI406, 45PI408, 45PI429, and 45PI438) from sites in the upper maritime forest and subalpine zone of Mount Rainier were compared. An evolutionary archaeology model was applied to define and measure variables relevant to stone tool manufacture and use. Statistically significant non-random associations were contextualized …

Edith Cowan University
An Appraisal Of Experiences Of Climate Change And Adaptive Response To Heat Stress By Farmers In Rural Ghana, Kwasi Frimpong
Theses: Doctorates and Masters
With the increase in average global temperatures, heat-related illnesses and deaths have unfolded as occupational and health issues. Periods of high to extreme temperatures are becoming more common and are a leading cause of weather-related deaths in many countries. In agricultural settings of African countries, heat stress is a major concern as many smallholder farmers work outdoors with limited access to cooling systems even in their resting and living environments. This study, conducted in the Bawku East part of Northern-East Ghana in 2013, examines, in the context of climate change, the trends and impacts of heat stress on smallholder farmers, …

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 …

Central Washington University
The Economic Impacts Of Forest Pathogens In Washington State: A Hedonic Approach, Logan Blair
All Master's Theses
An increase in the incidence of forest pathogens in the Western US has created new resource management issues. In this research I employ a dataset of 170,141 housing transactions in twelve Western Washington counties to quantify the impacts of parasitic forest damage on the proxy real estate market. Specifically, I estimate a set of hedonic fixed effects models to control for omitted variable bias and spatial autocorrelation. Results show statistically significant impacts on property values in the presence of species specific and aggregate defoliation, suggesting new information for forestry management and policy.
Behavioral Response Of Pacific Lamprey (Entosphenus Tridentatus) To Predator Odors,

Central Washington University
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 …
The Action Cycle/Structural Context Framework: A Fisheries Application,

Dartmouth College
The Action Cycle/Structural Context Framework: A Fisheries Application, D. G. Webster
Dartmouth Scholarship
There is a growing consensus that environmental governance is a wicked problem that requires understanding of the many linkages and feedbacks between human and natural systems. Here, I propose an action cycle/structural context (AC/SC) framework that is based on the concept of responsive governance, in which individuals and decision makers respond to problems rather than working to prevent them. By linking agency and structure, the AC/SC framework points out two key problems in the realm of environmental governance: the profit disconnect, whereby economic signals of environmental harm are dampened by endogenous or exogenous forces, and the power disconnect, whereby those …
A Basic Guide For Empirical Environmental Social Science,

Dartmouth College
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 …

Eco-Design Integration Into New Product Development Processes: Comparison Between Lca Software And Cad-Integrated Tools, Maria I. Hernandez Dalmau
Purdue Polytechnic Masters Theses
The constant growth of environmental concerns and in order to satisfy the increasing population demands, designers have started to integrate eco-design parameters in early design stages. The technological development that happened in the last decade has started to integrate LCA methods within CAD tools, allowing non-geometric data to be integrated in a typical geometrical model. The main research interest of this thesis is focused on the evaluation of the use of these emerging CAD tools, as tools capable to evaluate the futures environmental impacts of products and processes. This thesis studies through three comparative case studies if SolidWorks Sustainability as …

The Effects Of Insecticide Dose And Herbivore Density On Tri-Trophic Effects Of Thiamethoxam In A System Involving Wheat, Aphids, And Ladybeetles, Michael M. Bredeson, R Neil Reese, Jonathan G. Lundgren
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
We assess how herbivore density and insecticide dose affects the tri-trophic interactions among thiamethoxam-treated wheat (Triticum sp.), Rhophalosiphum padi and the predatory Coleomegilla maculata DeGeer. In the first experiment 2nd and 4th instar C. maculata were fed aphids reared for 24 h on wheat plants treated with sub-lethal thiamethoxam soil drenches to assess the effect of insecticidal dose on the predator. In the second experiment a constant, sub-lethal thiamethoxam soil drench was used on wheat plants, but the plants were infested with different densities of aphids. Aphids from each density treatment were then fed to C. maculata 2nd instars. Insecticide …
The Effect Of Corruption On Carbon Dioxide Emissions In The Mena Region,

The Effect Of Corruption On Carbon Dioxide Emissions In The Mena Region, Hoda Hassaballa
Economics
Corruption has always been accused of having adverse effects on growth. This is because it decreases productivity, leads to accumulation of additional costs and discourages investment. Recently, high concerns are raised about the impact of corruption on the environment. Corruption plays a substantial role in increasing pollution emissions level. In spite of this, empirical investigation of such an issue is still incomplete. For that, this research work represents a step forward in understanding the relationship between corruption and the environment in general and in filling the gap present in the literature in analyzing this relationship in the Middle East and …

The Damaging Effects Of Climate Change Denial, Richard Snow, Mary Snow
Publications
It has been said that those who are denying climate change are like the ostrich that sticks her head in the sand, but is this analogy entirely accurate? By hiding from the threat, does the ostrich make the threat go away, mitigate it, or make it greater? Probably, she does not. However, denying the existence of climate change does exacerbate the problem and exponentially so. As the renowned British economist Nicholas Stern reports, the longer world leaders wait to take serious action to curtail climate change, the more it will cost. As the Chair of the Grantham Research Institute on …

May You Walk In Beauty: The Decline Of Navajo Land And Culture, Jocelyn Catterson
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The Navajo homeland, Dinetah, is bordered by four mountains that are sacred to the Navajo people: two in Colorado, one in New Mexico, and one in Arizona. Historically, Navajo medicine men have traveled to these mountains to renew prayers and collect medicinal herbs. Today, the mountains, which exist outside of the reservation boundaries, are used for resource extraction and various recreational pursuits. While many Navajo are fighting for the protection of these sacred lands and their traditional culture, others are disinterested. Traditional practices and beliefs are slowly disappearing within the Navajo Nation. The land-use issues associated with these sacred mountains …

Crop Swap Missoula: Food Waste And The Sharing Solution, Cathryn Raan
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Rachel Botsman coined the term “collaborative consumption” to describe an economic model based on sharing, swapping, trading, or renting products and services, and enabling access rather than ownership1. Also referred to as the sharing economy, the mesh economy, or the peer-to-peer economy, collaborative consumption models offer a more efficient use of unused, or underutilized resources. Whereas previously peer-to-peer exchanges were only practical within small networks of friends, family, and neighbors, the Internet and mobile technology have allowed us to share almost anything at any time. While there are countless examples of community exchange platforms, and more springing up …
