Net Zero Energy Dairy Production: Powering Minnesota Dairy Farms With Renewable Energy, Mckenzie Dice

Honors Capstone Projects

The goal of this project was to determine if the West Central Research and Outreach Center (WCROC) dairy production could achieve a net zero energy status, meaning that the dairy operation uses as much as energy on-site as the amount of energy that is produced on-site for the dairy operation. There are several ways to accomplish this goal, principally through energy conservation, by means of installing more energy efficient technologies, as well as the installation of on-site renewable energy. At the WCROC dairy, a new utility room has been installed to introduce energy efficient technologies to the dairy operation, as …

Regime Shifts And Panarchies In Regional Scale Social-Ecological Water Systems, Barbara Cosens

Articles

In this article we summarize histories of nonlinear, complex interactions among societal, legal, and ecosystem dynamics in six North American water basins, as they respond to changing climate. These case studies were chosen to explore the conditions for emergence of adaptive governance in heavily regulated and developed social-ecological systems nested within a hierarchical governmental system. We summarize resilience assessments conducted in each system to provide a synthesis and reference by the other articles in this special feature. We also present a general framework used to evaluate the interactions between society and ecosystem regimes and the governance regimes chosen to mediate …

White Privilege In Environmental Policy: An Analysis Of Hazardous Waste Management And Operations In Southeast Los Angeles, Lindsey Chen

Scripps Senior Theses

This thesis takes an unconventional approach to environmental racism. Through the lens of white privilege and racial capitalism, I analyze hazardous waste procedures, work site dynamics, and governmental enforcement. Southeast Los Angeles encompasses 26 neighborhoods and the communities racial demographic is 85.8% people of color. The region is home to an abundance of hazardous waste generators, and the area is disproportionately burdened by pollution compared to the rest of LA County. I chose white privilege as a framework because more often than not, discrimination in the workplace is unintentional and covert. White privilege manifests through hazardous waste management in four …

Indigenous Peoples Boxed In By Brazil’S Political Crisis, Manuela Carneiro Da Cunha, Ruben Caixeta, Jeremy M. Campbell

Arts & Sciences Faculty Publications

Agribusiness has unprecedented leverage over highly unpopular Brazilian president Michel Temer, who is faced with several corruption charges and is struggling for political survival. In a little over one year, the agribusiness lobby and its allies have managed to erode thirty years of human rights and conservation laws. Indigenous peoples and their territorial rights are among the main targets of such policies, and there is no resolution to the situation in sight. With the insight of several scholars, the following forum assesses the consequences of losing the protection the Citizens’ Constitution of 1988 once afforded indigenous peoples in Brazil.

United States National Park Service: Publications

Background

The Upper Columbia Basin Network I&M (Inventory and Monitoring) program and Craters of the Moon National Monument and Preserve are collaborating to monitor winter bat use in Arco Tunnel, which is a safely accessed cave in the northern portion of the monument that consistently has been found with the largest number of bats (~30/year) among the set of caves recently inventoried. The standard operating procedures documented here and the methods described in the associated protocol narrative will also be used to periodically inventory other caves within the monument and surrounding preserve as park resources and safety (winter environmental and …

Risk Mitigation Through Diversified Farm Production Strategies: The Case In Northern Mozambique, Olivia C. Caillouet, Lawton L. Nalley, Amy L. Farmer

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Mozambique, like many other parts of the low-income world, faces perennial challenges with food security. With a rapidly growing population and arable land on the decline, sustainable agriculture is vital to managing the already depleted natural resources of Sub-Saharan Africa more effectively while increasing food security. Food security issues for subsistence farmers in most low-income countries are a product of endogenous (crop yields) and exogenous (currency fluctuations as many agricultural inputs are imported) factors. In Mozambique the value of the local currency, meticals, has decreased by approximately 50% since January 2015 compared to the U.S. dollar. While this makes exporting …

Potential Of Using Surfactants To Enhance Ammonium And Nitrate Adsorption On Rice Husk And Its Biochar, Lada Mathurasa, Seelawut Damrongsiri

Applied Environmental Research

Inorganic nitrogen fertilizers are widely and heavily used in agriculture. Leaching of these fertilizers is a cause of eutrophication in water bodies. This study examines the use of rice husk and its biochar, their efficiency in adsorption of ammonium and nitrate and the potential of using surfactants, sodium dodecyl benzenesulfonate (SDBS) and cetyl trimethyl ammonium bromide (CTAB), to increase adsorption. Physical and chemical properties of adsorbents were examined through BET, SEM-EDX, and CEC value, respectively. The equilibrium batch adsorption was conducted. The result showed that rice husk was lower in surface area, total pore volume, pore diameter, silica and oxygen …

Driving fatigue was assessed by both subjective questionnaire (n = 99) and flicker fusion instrument (n = 88). The association between driving fatigue and related factors were analyzed by Pearson's correlation and Chi-square (?2). The results revealed that the prevalence of fatigue as assessed by critical flicker fusion analyzer, subjective fatigue question and either one of the instruments were 32.32 %, 16.16 % and 43.43 …

Manganese Removal From Aqueous Solution By Ozonation Process Designed By Box-Behken Design (Bbd), Sunisa Jongdee, Tinnakorn Kumsaen, Kitirote Wantala

Applied Environmental Research

The aim of this research was to investigate interactions in the removal of manganese from contaminated water by oxidation through an ozonation process. The manganese oxidation was used to oxidize manganese ions (Mn2+) in solution to manganese dioxide (MnO2) in its brown solid form, in order to reduce levels of manganese ions in the water to below the acceptable limit for drinking water (0.05 mg L-1). In this study, the independent effects such as the initial concentration of manganese (5, 10 and 15 mg L-1), initial pH of solutions (3, 4 and 5) and ozone concentrations (10.970, 21.945 and 32.920 …

Assessment Of Watershed Condition And Vulnerability To Forecasted Land-Use/Land-Cover Change In The Northwestern Great Plains Of Western South Dakota, Aaron Suehring

Electronic Theses and Dissertations

A projected increase in global population by mid-century will likely further intensify agricultural practices given future demand for food, increasing the strain on the nation’s aquatic resources. Extensive water quality monitoring will be important in agriculturally dominated regions. The main objectives of this effort were to develop an approach to assess watershed condition and watershed vulnerability to land-use/landcover (LULC) change under multiple scenarios of future development. We used U.S. EPA’s Analytical Tools Interface for Landscape Assessment (ATtILA) to analyze landscape spatial data to determine the condition of wadeable, perennial stream watersheds in the Northwestern Great Plains level III ecoregion of …

Democracy In The Dark: An Energy Democracy Model Centering Property And People, Feby Boediarto

Pitzer Senior Theses

The United States’ electric macro-grid provides electricity for all people to sustain our lifestyle. The current governing institutions that generate our electricity limit community representation, causing procedural injustice particularly to communities of color. This thesis is a contribution to the Energy Democracy literature, describing a community-based electricity model that includes two components: property and people. I argue to include an in-depth study of John Locke’s theories on property, in addition to Elinor Ostrom’s Institutional Analysis and Development Framework to promote local knowledge in understanding how physical space and governing bodies strengthen the Energy Democracy movement. In addition, I utilize the …

The Economic Impacts Of Cougars In Western Washington, Todd Stoothoff

All Master's Theses

The combination of increasing cougar populations and the rising human population in Wildland-Urban Interface (WUI) areas suggests that the number of human-cougar encounters will rise as well. The increase in human-cougar encounters creates potential issues in regard to public safety, public policy, and management of predators. For the purposes of this research, I employ a housing dataset for eleven counties in western Washington in order to quantify the impacts of a confirmed cougar sighting on the sale value of a home. Specifically, I employ the hedonic real estate price model. Results show statistically significant impacts on housing values in the …

Drowning In Rising Seas: Navigating Multiple Knowledge Systems And Responding To Climate Change In The Maldives, Rachel Hannah Spiegel

Pitzer Senior Theses

The threat of global climate change increasingly influences the actions of human society. As world leaders have negotiated adaptation strategies over the past couple of decades, a certain discourse has emerged that privileges Western conceptions of environmental degradation. I argue that this framing of climate change inhibits the successful implementation of adaptation strategies. This thesis focuses on a case study of the Maldives, an island nation deemed one of the most vulnerable locations to the impacts of rising sea levels. I apply a postcolonial theoretical framework to examine how differing knowledge systems can both complement and contradict one another. By …

Politics Below The Surface: A Political Ecology Of Mineral Rights And Land Tenure Struggles In Appalachia And The Andes, Lindsay Shade

Theses and Dissertations--Geography

This dissertation examines how confusion and lack of access to information about subsurface property rights facilitates the rapid acquisition of mineral rights by mining interests, leaving those who live 'above the surface' to contend with complicated corporate and bureaucratic apparatuses. The research focuses on the first proposed state-run large scale mining project in Ecuador, believed to contain copper ores, and on the natural gas hydrofracking industry in three counties in north central West Virginia. Qualitative and visual methods, including mapping, are employed to determine (i.) how the geography of subsurface ownership patterns is changing, (ii.) links between changes in subsurface …

From Disposable Culture To Disposable People: Teaching About The Unintended Consequences Of Plastics, Sasha Adkins

Antioch University Dissertations & Theses

Plastics, the epitome of disposable culture, pose both a toxicological and a spiritual problem. This dissertation examines plastics at a molecular level using the discourse of endocrine disruption, and at a sociological level using the discourses of eco-theology and environmental justice. Adding to the literature on the adsorption of toxicants to plastic marine debris, I demonstrate that certain types of plastic -- those containing mercaptans, such as styrene butadiene block copolymer -- efficiently concentrate methyl mercury from seawater. Further, samples of polycarbonate contributed mercury to seawater. I propose the term plastic-mediated magnification to describe the phenomenon that plastics, along with …
