Thousands of these filters have been distributed and are currently in use in developing countries around the world, helping to alleviate poor water quality conditions. Although these filters have been proven to improve water quality in terms of biological contaminants, there are still concerns over their ability to …


Virgil In Virginia: Eighteenth-Century Pastoralism And The Novus Ordo Seclorum, Alley Jordan Aug 2016

Virgil In Virginia: Eighteenth-Century Pastoralism And The Novus Ordo Seclorum, Alley Jordan

Theses

This work examines classical reception in early America. Specifically, it addresses the role of classical ideas on pastoralism in the thought of one of America’s founders, Thomas Jefferson. Jefferson is best known for his role in the forming of United States government, but he was also influential on developing the idea of “America.” As such, his political theory on agrarian republicanism has strong ties to how the classical poets, such as Virgil and Theocritus, likewise thought about the relationship between land and government.

The Life And Times Of Landfills, Joshua O. Reno Aug 2016

The Life And Times Of Landfills, Joshua O. Reno

Journal of Ecological Anthropology

American landfills are primarily understood as distinctly human and spatial creations, when in practice they are as much temporal as spatial and as much non-human as human. Based on a large landfill on the rural periphery of Detroit, this paper explores the emergent and polychronic forms of life fostered by controlled dumping. Landfill employees work with their ecological surroundings to satisfy regulatory directives and assemble ever-growing mountains of waste. The paper introduces the complex, practical negotiations that result by isolating and diagraming the distinct temporal scales at which nonhuman beings and powers aid in and disrupt the process of landfilling.


Kain V. Department Of Environmental Protection, Sarah M. Danno Aug 2016

Kain V. Department Of Environmental Protection, Sarah M. Danno

Public Land & Resources Law Review

Global climate change and its chronic frustrations generated passage of the Massachusetts Global Warming Solutions Act. The Massachusetts Legislature imposed time-bound implementation mandates on the Massachusetts Department of Environmental Protection with Massachusetts residents acting as compliance watchdogs. In Kain, the Supreme Judicial Court of Massachusetts interpreted the Act in favor of environmental integrity and strict agency compliance standards.

A Review Of The Welfare Impact On Pinnipeds Of Plastic Marine Debris, Andrew Butterworth Aug 2016

A Review Of The Welfare Impact On Pinnipeds Of Plastic Marine Debris, Andrew Butterworth

Reduction and Degradation of Habitat Collection

Uncounted, and usually unobserved, numbers of pinnipeds find themselves entangled in lost fishing gear, monofilament line, nets, rope, plastic packaging in the ocean or on the shoreline. These animals may carry debris wrapped around themselves for long periods, and often die as a result, sometimes from deep chronic wounds. The pinniped species most affected by this modern and manmade phenomenon are fur seals, monk seals, and California sea lions, and to a lesser extent gray, common, and monk seals. Entanglement rates described range up to 7.9% of local populations annually, and the common entangling materials; packing bands, fragments of lost …


Industrial Ecology Analysis Of The Potential For An Eastern Nebraska Industrial Symbiosis Network (Enisn): A Comparative Study, Bradley A. Behne Aug 2016

Industrial Ecology Analysis Of The Potential For An Eastern Nebraska Industrial Symbiosis Network (Enisn): A Comparative Study, Bradley A. Behne

School of Natural Resources: Dissertations, Theses, and Student Research

The area of Eastern Nebraska north of Omaha, including the municipality of Blair is host to a collection of unique companies and industries. These industries, driven by the agricultural and urban economy of the area, as well as the geographic proximity to each other, make it an advantageous area to study the potential for a network where individual entities utilize the concept of industrial symbiosis. This potential network is referred to as the Eastern Nebraska Industrial Symbiosis Network (ENISN). Industrial symbiosis, a sub-set of industrial ecology, engages separate industries in a collaborative and collective approach, concerning itself with the flow …


Coastal Louisiana: Adaptive Capacity In The Face Of Climate Change, Tara Lambeth Aug 2016

Coastal Louisiana: Adaptive Capacity In The Face Of Climate Change, Tara Lambeth

LSU New Orleans Theses and Dissertations

Extreme weather events can result in natural disasters, and climate change can cause these weather events to occur more often and with more intensity. Because of social and physical vulnerabilities, climate change and extreme weather often affect coastal communities. As climate change continues to be a factor for many coastal communities, and environmental hazards and vulnerability continue to increase, the need for adaptation may become a reality for many communities. However, very few studies have been done on the effect climate change and mitigation measures implemented in response to climate change have on a community’s adaptive capacity.

This single instrumental …


Hidden Costs And Deadweight Losses: Bundled Parking Andresidential Rents In The Metropolitan United States, C. J. Gabbe, Gregory Pierce Aug 2016

Hidden Costs And Deadweight Losses: Bundled Parking Andresidential Rents In The Metropolitan United States, C. J. Gabbe, Gregory Pierce

Environmental Studies and Sciences

There is a major housing affordability crisis in many American metropolitan areas, particularly for renters. Minimum parking requirements in municipal zoning codes drive up the price of housing, and thus represent an important potential for reform for local policymakers. The relationship between parking and housing prices, however, remains poorly understood. We use national American Housing Survey data and hedonic regression techniques to investigate this relationship. We find that the cost of garage parking to renter households is approximately $1,700 per year, or an additional 17% of a housing unit’s rent. In addition to the magnitude of this transport cost burden …

Growing The Green Energy Economy: Workforce Development And Cluster Growth In The Pioneer Valley Of Massachusetts, Nicholas B. Altonaga

Sustainability and Social Justice

Workforce development programs have a positive effect on the formation of a cluster. Incorporating these programs into cluster theory is essential to creating more robust and dynamic local growth in the emerging green energy sector. Studying programs in the green energy sector in the Pioneer Valley has shown an increase in collaboration, local and regional connectivity, and industry communication. These aspects reinforce the comparative advantage of organizations within the cluster, while downplaying their challenges . Applying this focus on workforce development is important for cementing the green energy cluster into an enduring force in the domestic economy in the 21 …


The Feasibility Of Using Drones To Count Songbirds, Andrew M. Wilson, Janine M. Barr, Megan E. Zagorski Aug 2016

The Feasibility Of Using Drones To Count Songbirds, Andrew M. Wilson, Janine M. Barr, Megan E. Zagorski

Environmental Studies Student Conference Presentations

Point and transect counts are the most common bird survey methods, but are subject to biases and accessibility issues. To eliminate some of these biases, we propose attaching a recorder to a consumer-grade quadcopter (Unmanned Aerial Vehicle, or UAV) to estimate songbird populations from audio recordings. We conducted a blind experiment using broadcast recordings to estimate the detection radius of a compact recorder attached to a UAV, and found that the detection radius did not vary significantly when the UAV was flown at elevations of 20, 40 and 60m. We field tested our system by comparing UAV-based bird counts with …

Influences On Off-Highway Vehicle (Ohv) Recreation Use Patterns Within A Complex Trail System In Southwest Idaho, Eric Charles Frey Aug 2016

Influences On Off-Highway Vehicle (Ohv) Recreation Use Patterns Within A Complex Trail System In Southwest Idaho, Eric Charles Frey

Boise State University Theses and Dissertations

Off-highway vehicle (OHV) recreation on public lands provides participants with the opportunity to experience positive connections with nature; however, like all outdoor recreation activity, OHV use can have impacts on the environment. In order to maintain the health of the landscape and wildlife while also providing recreational opportunities, managers must make decisions based on sound biological and social science data. We hope this research provides knowledge that may aid in the implementation of sound management strategies that are successful in fulfilling these goals.

In the first chapter, in order to gain knowledge on OHV recreationists and their distributions across a …


Are Countries In Environmental Cooperation Concerned About Relative Gains?, Vivian Chinua Olivia Ike Aug 2016

Are Countries In Environmental Cooperation Concerned About Relative Gains?, Vivian Chinua Olivia Ike

Master's Theses

A country’s decision to join or withdraw from environmental cooperation has been argued by interest based theories to be influenced by the economic cost of international agreements, national interest of countries and the free-rider problem. However, this thesis argues that relative gains is a more decisive factor that influences the decision of countries in international arrangements. It hypothesizes that countries in environmental cooperation are concerned about relative gains. A content analysis of the statements of fifteen countries in international climate change cooperation are analyzed. The countries include the United States, Russian Federation, Canada, Japan, Australia, China, Brazil, South Africa, India, …

Electronic Waste And Sustainability: Reflections On A Rising Global Challenge, Bipul Kumar, Kalyan Bhaskar Jul 2016

Electronic Waste And Sustainability: Reflections On A Rising Global Challenge, Bipul Kumar, Kalyan Bhaskar

Markets, Globalization & Development Review

Globalization, technological advancements, advent of the internet, near-universal availability of mobile phones and changing consumer preferences have led to a boom in the electrical and electronics industry. Such products are now available in almost all countries of the world. The increased availability and consumption of electronic products have also led to rapid rise in the volumes of electronic waste (e-waste) globally. Markets have traditionally not paid sufficient attention to post-consumption behavior for electronic products and hence safe disposal and management of e-waste has always remained a critical issue. There are significant sustainability issues related with e-waste at local as well …

Understanding Women's Needs For Weather And Climate Information In Agrarian Settings: The Case Of Ngetou Maleck, Senegal, Edward Carr, Grant Fleming, Tshibangu Kalala Jul 2016

Understanding Women's Needs For Weather And Climate Information In Agrarian Settings: The Case Of Ngetou Maleck, Senegal, Edward Carr, Grant Fleming, Tshibangu Kalala

Sustainability and Social Justice

While climate services have the potential to reduce precipitation- and temperature-related risks to agrarian livelihoods, such outcomes are possible only when they deliver information that is salient, legitimate, and credible to end users. This is particularly true of climate services intended to address the needs of women in agrarian contexts. The design of such gender-sensitive services is hampered by oversimplified framings of women as a group in both the adaptation and climate services literatures. This paper demonstrates that even at the village level, women have different climate and weather information needs, and differing abilities to act on that information. Therefore, …
