Patagonia Con Poder: El Éxito De La Oposición Frente El Proyecto Hidroaysén, Nathaniel Korn Oct 2015

Patagonia Con Poder: El Éxito De La Oposición Frente El Proyecto Hidroaysén, Nathaniel Korn

Independent Study Project (ISP) Collection

This investigation analyzes the movement in opposition to the HidroAysén project in Southern Chile that is often referred to as and uses the slogan “Patagonia Sin Represas” (Patagonia Without Dams). The investigation is framed through collective action theory, the study of what incentives and other factors create the conditions for mobilization and group action. In the context of social movements it is usually argued that there needs to be a better cost-benefit scenario for each actor to be involved than there is to not be involved in the movement. Immediately following return of democracy to Chile in the 1990’s social …


The Environment And Civil War: Exploring The Relationship Between The Environmental Performance Index And Incidence Of Internal Armed Conflict, Katerina N. Krohn Oct 2015

The Environment And Civil War: Exploring The Relationship Between The Environmental Performance Index And Incidence Of Internal Armed Conflict, Katerina N. Krohn

Student Publications

The state of the environment is receiving increasing attention. Environmental quality’s possible relationship to violent conflict attracts both popular and academic interest. Prior research has found support for the idea that environmental scarcity is related to higher occurrences of civil war. There have been few comprehensive quantitative studies regarding this relationship. This study tests a more general argument that higher environmental quality can lead to fewer occurrences of internal armed conflict. The study utilizes an environmental performance index found in the Quality of Government Standard Dataset to test its hypothesis. The study finds that the higher the environmental performance index …


Assessing The Sustainability Of Selective Logging In Ankarabolava-Agnakatrika New Protected Area, Eileen Nakahata Oct 2015

Assessing The Sustainability Of Selective Logging In Ankarabolava-Agnakatrika New Protected Area, Eileen Nakahata

Independent Study Project (ISP) Collection

Over the past 50 years, more than 90% of dense low-altitude humid forest in the District of Vangaindrano has been lost to deforestation and the remaining fragments continue to be threatened by slash and burn agriculture and selective cutting by local populations. These activities are driven by widespread poverty, population growth, and lack of development, which have made subsistence increasingly difficult. This study investigates logging rates and the stock of five commercially valuable trees in the Ankarabolava-Agnakatrika New Protected Area. Fifteen 1000m2 transects were established systematically within the territory of the Matanga commune. Within each transect data was collected …


Landscape Values And Wind Generation In West Mayo, Ireland, Ken Boyle Sep 2015

Landscape Values And Wind Generation In West Mayo, Ireland, Ken Boyle

Conference Papers

The landscape of west Mayo, in North West Ireland, is dominated and shrouded by an extensive area, 3,539Km2, of blanket peat soils. The landscape and its habitats have multiple values associated with them including a source of peat for fuel, agriculture, forestry, conservation, tourism, biomass production, tourism, cultural and archaeological. Historically communities have relied on peat as a source of energy and in the 20th century the state harvested peat on an industrial scale to generate electricity. Biomass production using willow (Salix spp) on cutover blanket peat and extensive planting, on deep peat, of Picea sitchensis and Pinus contorta was …

Simulating And Animating The Spatial Dynamics Of Interacting Species Living On A Torus, Boyan Kostadinov

Publications and Research

The goal of this talk is to present a student research project in computational population biology, which aims at creating a computer simulation and animation of the spatial dynamics of interactions between two kinds of species living on a torus-shaped universe. The habitat for spatial interactions is modeled by a 2D lattice with periodic boundary conditions, which wrap the rectangular grid into a torus. The spatial interactions between the species have two components: 1. Population dynamics modeled by the classical Nicholson-Bailey two-parameter family of models for coupled interactions between species, extended to incorporate space and 2. Two-parameter migration dynamics, modeled …


The Price Of Snow: Albedo Valuation And A Case Study For Forest Management, David A. Lutz, Richard B. Howarth Jun 2015

The Price Of Snow: Albedo Valuation And A Case Study For Forest Management, David A. Lutz, Richard B. Howarth

Dartmouth Scholarship

Several climate frameworks have included the role of carbon storage in natural landscapes as a potential mechanism for climate change mitigation. This has resulted in an incentive to grow and maintain intact long-lived forest ecosystems. However, recent research has suggested that the influence of albedo-related radiative forcing can impart equal and in some cases greater magnitudes of climate mitigation compared to carbon storage in forests where snowfall is common and biomass is slow-growing. While several methodologies exist for relating albedo-associated radiative forcing to carbon storage for the analysis of the tradeoffs of these ecosystem services, they are varied, and they …


Using An Obcd Approach And Landsat Tm Data To Detect Harvesting On Nonindustrial Private Property In Upper Michigan, Riccardo Tortini, Audrey L. Mayer, Pieralberto Maianti Jun 2015

Using An Obcd Approach And Landsat Tm Data To Detect Harvesting On Nonindustrial Private Property In Upper Michigan, Riccardo Tortini, Audrey L. Mayer, Pieralberto Maianti

College of Forest Resources and Environmental Science Publications

Forest dynamics influence climate, biodiversity, and livelihoods at multiple scales, yet current resource policy addressing these dynamics is ineffective without reliable land use land cover change data. The collective impact of harvest decisions by many small forest owners can be substantial at the landscape scale, yet monitoring harvests and regrowth in these forests is challenging. Remote sensing is an obvious route to detect and monitor small-scale land use dynamics over large areas. Using an annual series of Landsat-5 Thematic Mapper (TM) images and a GIS shapefile of property boundaries, we identified units where harvests occurred from 2005 to 2011 using …

Environmental Social Activism In The San Diego-Tijuana Transborder Region, Christina M. Hirt May 2015

Environmental Social Activism In The San Diego-Tijuana Transborder Region, Christina M. Hirt

Undergraduate Honors Theses

This paper examines the obstacles and opportunities social activists face when attempting to fight environmental injustices in the San Diego-Tijuana transborder region. The study undertakes a case study of the Environmental Health Coalition (EHC) - the leading environmental justice organization in the region, which operates on both sides of the US-Mexico Border. The analyses conclude that despite a strong rhetoric of binationalism employed throughout border activists’ campaigns, the strategies that are utilized on the ground have been vastly local and short-term in focus. While activist organizations like the EHC demonstrate a keen awareness of the binational implications of environmental injustices …


Ecodistricts In San Francisco: The Implementation Of Neighborhood Regional Planning And Its Potential Effects On Environmental Resilience, Elizabeth M. Juvera May 2015

Ecodistricts In San Francisco: The Implementation Of Neighborhood Regional Planning And Its Potential Effects On Environmental Resilience, Elizabeth M. Juvera

Master's Projects and Capstones

Ecodistricts, or neighborhood-scale, community-driven areas of sustainable development, have emerged internationally and within the U.S. to create models of adaptive environmental design and advanced urban infrastructure. Central SoMa is the first ecodistrict to be planned and implemented in San Francisco, with the intention of revitalizing and greening this urbanized region of the city. At this time, the Central SoMa area has very low biodiversity levels, inefficient infrastructure, and poor water management capabilities. Through the implementation of ecodistricts in San Francisco, the city can integrate physical and behavioral sustainability measures from existing ecodistricts such as permeable surfaces, green roofs, stormwater management, …

Academic Incoherence: The State Of Sustainability Literature Today, Anthony Philip Stine May 2015

Academic Incoherence: The State Of Sustainability Literature Today, Anthony Philip Stine

Student Research Symposium

The traditional tools associated with researching and presenting findings in contemporary sustainability literature include very little representation on moral forms of discourse. In the context of social sustainability this is problematic due to the inherently normative nature of the discourse. A citation analysis reveals very little representation of Christian moral environmental claims in the sustainability literature today despite growing concern amongst Christians for the state of the environment today.

Estimating Stormwater Runoff For Community Gardens In New York City, Mara Gittleman

Theses and Dissertations

While much of the literature cites community gardens as providing urban ecosystem services, there is very little research quantifying these benefits. This thesis compares the stormwater runoff rates of urban vacant lots, community gardens, and residential developments in New York City and evaluates community gardens as green infrastructure.


Impacts Of Consumer Horticulture On Stormwater And Nutrient Management: Investigating Public Perception, Knowledge, And Practices In The Shenandoah River Watershed, Christopher P. Parker May 2015

Impacts Of Consumer Horticulture On Stormwater And Nutrient Management: Investigating Public Perception, Knowledge, And Practices In The Shenandoah River Watershed, Christopher P. Parker

Masters Theses, 2010-2019

The South Fork Shenandoah River is a tributary to the Chesapeake Bay that is a significant contributor to nitrogen and phosphorus that enter the Bay and leads to increased eutrophication. These nutrients also cause problems in the South Fork Shenandoah River. The United States Environmental Protection agency has implemented strict regulation to reduce nutrients entering the Bay by developing the Chesapeake Bay TMDL. While the TMDL has strict regulation on wastewater treatment, agriculture, and industry, there are still sources of nutrients entering the Bay through unregulated sources. Urban/suburban runoff is one of these sources, particularly runoff from home owner’s lawns. …


Shorebird Migratory Stopover Responses To Local And Regional Change: Habitat Decisions In A Vanishing Landscape, Caitlyn Gillespie May 2015

Shorebird Migratory Stopover Responses To Local And Regional Change: Habitat Decisions In A Vanishing Landscape, Caitlyn Gillespie

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

Understanding the consequences of anthropogenic change for migratory species is challenging because although they have evolved to cope with environmental uncertainty, migrants still rely on predictable relationships within and among habitats to make informed decisions. Calidris shorebirds rely on ephemeral wetlands during northward migration through mid-continental North America, where favorable habitat conditions are annually and regionally unpredictable and increasingly altered by land-use change. During spring 2013 and 2014, we assessed Calidris habitat use in the Rainwater Basin (RWB) and the Prairie Pothole Region (PPR) at both local and landscape scales. Although anthropogenic change has altered the wetland landscape in both …


Supplier Selection Criteria For Sustainable Supply Chains, Amy Terracciano Apr 2015

Supplier Selection Criteria For Sustainable Supply Chains, Amy Terracciano

Honors Projects in Management

In today’s global business environment, suppliers can have a significant impact on the buyer’s supply chain. Selecting the right supplier can be a critical decision for manufacturers and distributors, and to aid in the supplier selection decision making process a large number of selection criteria have been proposed in the literature. Supplier selection criteria have traditionally focused on metrics that impact the buyer’s costs. But due to increased business awareness of the importance of sustainability, supplier selection criteria have now come to include measures on environmental and social performance. While environmental metrics for supplier selection have received some attention in …

This study is a preliminary assessment of the ecological and social factors influencing project implementation. Information was collected using a variety of qualitative methods including meeting observation, surveys, interviews, photographs, and a review of previous …


The Himalayan Gold Rush The Untold Consequences Of Yartsa Gunbu In The Tarap Valley, Noah Stone Apr 2015

The Himalayan Gold Rush The Untold Consequences Of Yartsa Gunbu In The Tarap Valley, Noah Stone

Independent Study Project (ISP) Collection

Despite the fact that it has been used in tradition medicine for centuries, the caterpillar fungus known as yartsa gunbu (Othiocordyceps sinensis), has only become a popular medical supplement in the last fifteen years. Demand in China has driven what has been dubbed ‘the Himalayan gold rush’, a scramble for the fungus that has utterly transformed the agro-pastoral economies of the remote Himalayan regions where cordyceps is found. In many cases, the locals have prospered economically from the commodification of yartsa gunbu. In one such region of Nepal, the Tarap valley of the Dolpa district, while the villagers have benefitted …


Existential Avalanche The Lived Experience Of Climate Change In Dolpo And Mustang, Nepal, Keegan Mcchesney Apr 2015

Existential Avalanche The Lived Experience Of Climate Change In Dolpo And Mustang, Nepal, Keegan Mcchesney

Independent Study Project (ISP) Collection

Himalayan communities stand precariously in an era of phenomenological uncertainty. Climate change is merely a lens through which we may observe and begin to understand such localized modern complexities. The people of the Tarap Valley in Dolpo, Nepal have experienced an increase in avalanches, snow leopard attacks and unpredictable precipitation patterns in recent years. In upper Mustang, Nepal, people have endured the harshest winter in generations and suffered from reduced water access. Environmental, climatic and weather related changes in both Himalayan districts have severely impacted traditional livelihoods and led some to adopt modern means of adaptation. Despite the scientific evidence …

Looking Through The Lens Of Size: Land Use Regulations And Micro-Apartments Insan Francisco, C. J. Gabbe Jan 2015

Looking Through The Lens Of Size: Land Use Regulations And Micro-Apartments Insan Francisco, C. J. Gabbe

Environmental Studies and Sciences

Small studio apartments, or micro-apartments, represent a market response to high housing costs in several major American cities. San Francisco, California, is one of the nation’s most expensive housing markets and the location of an innovative pilot microapartment policy. The literature on regulatory barriers to affordable housing has yet to pay much attention to minimum unit-size requirements. This article uses two prototype buildings to illustrate regulatory barriers to smaller units, including minimum parking standards in some parts of the city, outdoor open-space and indoor common-space provisions, unit-mix stipulations, and inclusionary zoning requirements. I recommend that cities review their codes through …


When Wells Run Dry: Water And Tourism Along The Western Coast Of Nicaragua, Gary Thomas Lavanchy Jan 2015

When Wells Run Dry: Water And Tourism Along The Western Coast Of Nicaragua, Gary Thomas Lavanchy

Electronic Theses and Dissertations

This dissertation uses a political ecology approach to examine the relationship between tourism development and groundwater in southwest Nicaragua. Tourism in Nicaragua is a booming industry bolstered by ‘unspoiled’ natural beauty, low crime rates, and government incentives. This growth has led to increased infrastructure, revenue, and employment opportunities for many local communities along the Pacific coast. Not surprisingly, it has also brought concomitant issues of deeper poverty, widening gaps between rich and poor, and competition over natural resources. Adequate provisions of freshwater are necessary to sustain the production and reproduction of tourism; however, it remains uncertain if groundwater supplies can …
