Conservation For Whom?: The Struggle For Indigenous Rights In Sagarmatha National Park, Jake Sivinski Oct 2015

Conservation For Whom?: The Struggle For Indigenous Rights In Sagarmatha National Park, Jake Sivinski

Independent Study Project (ISP) Collection

Since its creation in 1976 Sagarmatha National Park has been the subject of a great deal of internal scrutiny by the regions indigenous Sherpa Inhabitants. Since their arrival in the Khumbu valley some four centuries ago, the Sherpa people have held a deep respect for their land and have practiced a highly organized and effective form of environmental stewardship which they refer to as Yul-Tim. At its core Yul-Tim relies on the authority of certain village members to make and enforce rules within the community: a practice that has been greatly undermined by creation of SNP. While SNP has had …

An Avian Biological Gradient Across Tropical Dry Lowland Local Habitats At Playa Venao, Los Santos Province, Panama, Abigail Thomas

Independent Study Project (ISP) Collection

There are a myriad of forest types within Panama, varying by elevation, precipitation and other abiotic factors, which hosts a wide variety of native and migratory species in uniquely-structured avian communities. Panama has been well assessed for presence and distribution of its 987 collective avian species (Angehr, 2014). However most studies in Panama have been broad in scope, overlooking the highly specified habitats that are uniquely structured to host a certain range of avifauna communities. The distinctions in community structure of avifauna along a coastal to inland gradient were assessed among three specialized habitats: the Central Pacific coast, partially deforested …

An Analysis Of Biodiversity, Sustainability, And Ecotourism In The Vo.I.M.Ma Community Managed Forest, Andasibe, Madagascar, Catherine Knowlton, Charlotte Walton

Independent Study Project (ISP) Collection

The concept of eco-tourism as a culturally sensitive, ecologically beneficial alternative to traditional vacations is a fairly new idea. While on the surface it seems positive for everyone involved, there are complexities in the relationships between all parties. This study explores the ties between the community forest, the tourists, and biodiversity (specifically endemic lemur populations) in the VO.I.M.MA Community Managed Forest. This study found that the community forest model is sustainable, based on the criteria of protecting biodiversity and satisfying customers. To truly promote a sustainable business model in the future (ecologically as well as economically), the center could improve …


Impact Of Invasive Species Datura Arborea On Plant Species Richness In The West Usambara Mountains, Megan Foley Oct 2015

Impact Of Invasive Species Datura Arborea On Plant Species Richness In The West Usambara Mountains, Megan Foley

Independent Study Project (ISP) Collection

Invasive species have the potential to alter the evolutionary trajectory of ecosystems and native species; however, our understanding of the community level effects of invasive plants remains poor. The Eastern Arc Mountain Chain is listed as one of the top 25 biodiversity “hotspots” of the world, yet also as one of the 17 most threatened tropical forest ecosystems worldwide. The primary threat to biodiversity in the EAM is accredited to human encroachment; however, the impact of invasive species in the EAM, and across Tanzania, remains poorly understood. National biodiversity and resource management policy do not directly address invasive species, and …

Water Quality In The Río Pastaza Watershed A Comparative Study Of Ríos Topo, Zuñag, And Pastaza And The Impact Of The Topo Hydroelectric Project Using Macroinvertebrates As Bioindicators, Jesse Vega-Perkins

Independent Study Project (ISP) Collection

Ríos Zuñag, Pastaza, and Topo flow through one of the rainiest and water-rich places in Ecuador. Río Zuñag is a relatively small, pristine montane river and Río Pastaza is a relatively large, contaminated river that receives the untreated wastewater of many communities. Río Topo’s unique watershed and gradient allow it to be home to many plants that have adapted to its unique environment, including the hyperendemic liverwort Myriocolea irrorata. However, in recent years, all of the water of Río Topo has been sold by the state of Ecuador to be developed for hydroelectric projects (HEP). The first of these …


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 …

Working With Locals To Restore Biodiversity To A Rubber Dominated Landscape, Francis Commercon

Independent Study Project (ISP) Collection

Xishuangbanna, in Yunnan,China, contains the country’s highest concentration of biodiversity. Since the 1980s,rubber plantations have replaced a significant portion of the prefecture’s lowland Seasonal Tropical Rainforest, leading to wildlife habitat loss and other environmental issues.Monoculture farming practices also leave farmers economically vulnerable to market fluctuations. To learn the best solutions for increasing ecosystem services and income stability in rubber-dominated areas, the World Agroforestry Center (ICRAF) project Green Rubber engages smallholders directly in establishing and maintaining scientifically rigorous intercropping experiments in their villages.

Using Man’e village and the Green Rubber project as a case study, I asked to what degree and …


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 …

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 …


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 …
