Evaluating Amphibian Vulnerability To Mercury Pollution From Artisanal And Small-Scale Gold Mining In Madre De Dios, Peru, Kate Markham

Sustainability and Social Justice

Environmental hazards commonly associated with gold mining include local pollution of the air, water, and soil. Specifically, mercury used to extract gold bioaccumulates in the environment, contaminating rivers and watersheds and posing a danger to wildlife in regards to its developmental, hormonal, and neurological effects. To conceal these typically illegal operations happening along rivers, artisanal and small-scale gold mining (ASGM) often occurs in remote areas with high faunal biodiversity. The Madre de Dios region of southern Peru is a global biodiversity hotspot and has been undergoing extensive ASGM for years. The impact of ASGM on biodiversity is largely unknown. This …

Territoriality, Narratives And Violence: Stories Of Eight Women Living In The Presence Of A Large-Scale Mine In Ecuador, Chelsea N. Viteri 7742622017

Sustainability and Social Justice

Women play a substantial role in communities that are affected by mining nevertheless, their role has not been well documented and their voices and experiences have not been centered in the debates around extraction. In Ecuador, local rural, campesina, and indigenous women bear much the cost of large scale development projects, as their bodies, families, homes, environments and economies are impacted. This paper emerges from eight semi-structured interviews with indigenous and campesina women from Tundayme, a small rural town which is in the middle of the first large scale mine in Ecuador. Using a feminist political ecology framework and storytelling, …

An Analysis Of Structural And Psychological Barriers To The Adoption Of Demand Response Smart Grid Technologies: Lessons Learned, John M. Richards

Sustainability and Social Justice

Over the past decade, America’s utility grid has undergone fundamental changes on a scale not seen during the past 100 years (Energetics Incorporated, 2014). These changes have largely been driven by the need to replace aging infrastructure, modernize the grid, incorporate new sources of energy, and better balance the supply and demand of energy. In order to address some of these changes, utilities have increasingly implemented smart grid programs that provide customers with consumer-focused demand response technologies that aim to reduce peak demand. This report examined the success these technologies have in reducing peak demand for smart grid programs by …

Urban Wind Generation: Comparing Horizontal And Vertical Axis Wind Turbines At Clark University In Worcester, Massachusetts, Andrew R. Winslow

Sustainability and Social Justice

Electricity production must shift towards carbon neutral sources such as wind power to mitigate the impacts of climate change. The wind resource in urban environments is challenging to predict but technologies, including computational fluid dynamics software, are making it possible. This software pinpoints suitable placement for wind turbines through models that show wind acceleration patterns over a building. Horizontal axis wind turbines (HAWTs) have dominated the wind industry but vertical axis wind turbines (VAWTs) offer potential to outperform HAWTs in urban environments. VAWTs can handle turbulent and unconventional wind and generate energy at slower speeds, which is beneficial for these …

Aquaponics: Redefining Education For Our Youth, Joshua Peal

Senior Theses

In America, we are seeing a lack of effectiveness with our K-12 schools. This costs the school districts and taxpayers money with very little return guaranteeing an ongoing investment into adulthood. Students finishing high school have very little if any applied learning and technical skills, and still need to accomplish at least four years of college or a trade school to be able to compete, even for a job not requiring a degree. Of those high school graduates, half and growing do not feel that they are prepared for college. Students also have little understanding of, or experience with, the …

Governing The Urban Water Commons : Essays On Collaborative Policy Networks In A Polycentric Ecology Of Urban Water Policy Games., Emmanuel Frimpong Boamah

Electronic Theses and Dissertations

Governing social-ecological systems, such as the urban water commons, is a multi-scale and multi-sector (polycentric) human-environment process. This dissertation interrogates this process by situating itself within the Ecology of Games Framework by Norton Long (and updated by Mark Lubell) and the literature on polycentric governance by the Bloomington School of Political Economy. The dissertation’s three essays 1) offer both theoretical and methodological means to enact polycentric public economies within the ecology of games framework, and 2) explicate the conditions under which interoganizational collaboration is fostered within a polycentric ecology of policy games in governing the Middle Rio Grande urban watershed. …

The Cost Of Direct And Indirect Potable Water Reuse In A Medium Sized Inland Community, Jason Glenn Herman

Water Resources Professional Project Reports

In the face of increasing population, development pressures, and climate change, many regions around the world face freshwater shortages. Planned potable water reuse can improve sustainability and reliability of water supplies by providing drinking water from wastewater. Most potable reuse research has focused on large coastal communities with relatively high mean household incomes. However, the US Department of Interior predicts that “hot spots” of conflict over water in the arid West are “highly likely” in numerous small-to-medium-sized inland communities with low-to-moderate household income levels. Potable reuse options may be different for larger, wealthier coastal communities as compared to small-to-medium-sized inland …

The Lebanese Trash Crisis, Araz Khajarian

ENV 334 Environmental Justice

Thinking about what it means to be a human being in the 21st century comes with many different aspects that one needs to take into consideration. Human Rights is becoming more complicated as life requires more in some areas and less in other as it proceeds. Clean air and water are one of those rights that every human being should have access to. When humans are denied access to those two, especially for political or class stratification reasons, a case of environmental injustice should be identified. Not everyone has equal access to all resources neither does everyone consume the same …

Micro Plastics And Their Implications For Human Health: An Environmental Justice Approach, Alexis Smith

ENV 334 Environmental Justice

Studies have shown microplastics are ubiquitous within global waterways. They have been found in waterways that supply drinking water to millions and they have also been found at various levels within the aquatic food chain. This implies that, not only are we eating microplastics, we are drinking them too. What does the reality that we are consuming plastic daily mean for humans as a species?
