Women In Conservation: A Study Of Effective Community-Based Conservation And The Empowerment Of Women In Tanzania, Ruby Krietzman

Independent Study Project (ISP) Collection

The subject of this study is women involved in Community-Based Conservation (CBC) from areas surrounding Lake Manyara National Park, Ngorongoro Conservation Area, and Mount Kilimanjaro National Park. CBC is a participatory process between people and organizations who have responsibilities affecting conservation. Communities surrounding protected conservation areas tend to experience high levels of poverty and marginalization due to exclusive conservation policies and the lack of co-management principles. Although tourism revenue is abundant in these locations, the benefits rarely impact local community members that disproportionately experience the effects of conservation. This is especially true for women who hold the responsibilities of collecting …

Small-Scale Farming Of Sandfish (Holothuria Scabra) At Unguja Ukuu, Zanzibar, Claire Hacker

Independent Study Project (ISP) Collection

The biological and social components of sandfish farming were studied at Unguja Ukuu, Zanzibar. Measurement of temperature and depth, along with quadrat sampling of substrate and sea cucumbers, led to recommendations for future management of depth, biomass per area, disease and crabs, and substrate. Interviews revealed the role and potential benefits of sea cucumber farming for communities. Several barriers to, and complications with, the expansion of sea cucumber farming were also identified. This study provided information for improvement of this farm and hoped to spread knowledge of sandfish farming to Zanzibaris, who may benefit economically from the practice.

Wildlife Underpasses: Frequency Of Use By Neotropic Mammals In Parque Natural Metropolitano, Panamá City, Panamá, Kelly Russo

Independent Study Project (ISP) Collection

In a world of ever increasing globalization and urbanization, roads present wildlife with a number of challenges. They fragment habitats, disrupt animal movements, impact reproductive success and the fitness of individuals and populations, alter population dynamics, and cause unnatural levels of mortality. Fortunately, the numerous detrimental effects of roads can be alleviated by the proper implementation of mitigation structures, such as underpasses, sky bridges and vegetated overpasses. These mitigation structures are an important source of genetic connectivity, especially in a peri-urban reserve setting. This study seeks to understand what species of mammal utilize the wildlife underpasses below Via La Amistad, …

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

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 …

Taming The Teesta: Exploring The Holistic Effects Of Hydroelectric Dam Development On The Teesta River Through Documentary Film, Taylor Graham

Independent Study Project (ISP) Collection

Since time immemorial, the Lepcha people have called the Himalayan region that makes up the modern state of Sikkim their home and have held sacred the rivers, mountains, and forests that make up the biologically diverse region. Over the past two decades, India’s rapid development has generated a powerful thirst for electricity, and the country has increasingly looked to the cold, powerful rivers thundering from the Himalayas to supply that desired power. Hydroelectric projects have been proposed and implemented throughout the Himalayan region. Nowhere, however, are the dams as numerous or their effects as acutely felt as in India’s northwestern …

The Optimal Foraging Of Equus Burchelli At Enashiva Nature Refuge, Edward Haubenreiser

Independent Study Project (ISP) Collection

Within the country of Tanzania lies a vast ecosystem known as the Serengeti. This unique landscape, primarily of grasslands and woodlands, shapes the seasonal feeding habits of the abundant wildlife that call the area home. While these feeding habits on a large spatial scale are well understood, such behavior within a specie’s specific environment remains of interest. With the theory of optimal foraging in mind, which considers how animals should look for and select food (Green, 1990), I studied the foraging habits of resident Burchell’s zebra (Equus burchelli) by observing if they move and forage among distinct resource …

Independent Study Project (ISP) Collection

National parks are created and used for a variety of purposes but are primarily important for the conservation of natural resources and use by visitors. While park use is meant to be non-destructive, human interaction causes changes in ecosystems, leading to conflicts between these goals. Here, I examine the causes of trail degradation and impacts on surrounding forests in Parque Internacional la Amistad (PILA), Panama. This park is a world heritage site with the primary goal of preserving some of the world’s most diverse ecosystems including rare and endangered species. However, the park entrance in Las Nubes, Cerro Punta receives …

Las Raíces De La Deforestación En El Departamento Pando, Jeremy Levine-Drizin

Independent Study Project (ISP) Collection

This research paper examines the phenomenon of the recent trend of deforestation in the Pando department in northwestern Bolivia. Historically, the economy of Pando has always been based primarily in agro-forestal extraction activities that provided income to communities without the need to destroy the surrounding forests. The most important of these agro-forestal products have been rubber (primarily during the beginning of the 20th century) and more recently Castaña (Brazilian Nut). Recently however, as the result of various forces, the inhabitants of Pando have begun to cut down there forests at an alarming rate. The most relevant causes of this phenomenon …

Birds were observed in two of the main habitats present on Uzi Island, intertidal/mangrove and coral-rag. Three transects were cut and laid through each of the two habitats and monitored in the morning and evening hours over the course of 20 days. A total of 1949 birds were recorded comprising 71 species (708 …

Comparison Study Of Fish Species Richness Of Two Mangrove Forests On Misali Island: Eastern (Extractive) V. Western (Core) Mangrove Forests, Spencer M. Mallette

Independent Study Project (ISP) Collection

The fish species richness of two mangrove forests adjacent to non-extractive and extractive zones, respectively, was investigated on Misali Island, Tanzania. Observations were done at each site for seven samplings, recording the different species observed upon each visit. A general list of species found in the intertidal area was also composed to get an idea of what species use this region as well. A total of twenty-four species were observed between the two sites, leading to a similarity index of 0.29, representing very little similarity between the two stands. Two different diversity indices (Shannon-Wiener and Simpson’s) also supported the hypothesis …

“Hariyo Ban Nepalko Dhan” (“Nepal’S Wealth Is The Green Forest”): The People’S Participation In Structuring Sustainable Development Through Community Forestry, Natasha Eulberg

Independent Study Project (ISP) Collection

Community forestry has a long history in Nepal, and despite the nationalization of the country’s forests in the mid-twentieth century, current legislation determines that rights and execution of community forest management lies largely with community forest user groups (CFUGs). This research questions to what extent CFUGs truly represent autonomous bodies with the full power and ability to manage and utilize community forests and forest resources. This research also seeks to determine the impact and distribution of CFUG operations and benefits on CFUG members, and the ways in which CFUG management practices have impacted how group members perceive and interact with …

Too Much Weed: Invasive Species In Chitwan National Park, Laura Nelson

Independent Study Project (ISP) Collection

Invasive plant species threaten jungle eco-systems in Chitwan National Park. Mikania micrantha is the most destructive invasive plant in the park and has been named one of the world’s 100 worst invaders. It is an exceptionally fastgrowing and aggressive perennial plant that is quickly spreading throughout Chitwan and ousting native plant species that comprise the diets of rhinos and other important wildlife species. M. micrantha poses both immediate ecological concerns to wildlife and threatens rural subsistence farming populations by destroying cropland.

Coarse Woody Debris In A Tropical Rainforest In North Queensland, Australia: Relationships With Stand Structure And Disturbance, Nadine Rea

Independent Study Project (ISP) Collection

Coarse woody debris (CWD) refers to the woody material on the forest floor, including fallen stems, large branches, coarse roots, wood pieces, and standing dead trees (snags) (Harmon et al. 1986). CWD is an essential but often overlooked aspect of ecosystems. It plays many key ecosystem roles and is instrumental in overall ecosystem functionality. While a piece of CWD decomposes, it provides key habitat for many different species, minimizes soil erosion, affects soil development, stores nutrients and water, and influences the global carbon cycle (Harmon and Hua 1991). In some forests, CWD can exist on the forest floor for hundreds …

A Study Of Sponge Aquaculture In Jambiani: Is Shallow Farming Feasible?, Sarah Friday

Independent Study Project (ISP) Collection

In the village of Jambiani, Unguja, a Swiss NGO called Marine Cultures has established an experimental sponge farming initiative to improve local employment and support economic development. Currently, the main farming site is only accessible through SCUBA diving. This is consistent with experimental farm sites in other oceanic regions, as most are located in depths of at least five meters with sponges suspended vertically to maximize water flow exposure. Farms located in shallower water may not be conducive to sponge growth due to highly variable environmental conditions; however, no conclusive research has been conducted on this matter (Duckworth 2009). Nonetheless, …

Exploring Marine Conservation Efforts In Tasmania: An Internship With Ocean Planet, Lauren Markram

Independent Study Project (ISP) Collection

I chose to conduct a dual internship with Environment Tasmania and Ocean Planet. Although I was located in the ET office and conducted participant observation within that environment, I specifically worked on the Ocean Planet campaign to promote marine conservation efforts throughout Tasmania. I was drawn to this internship because the oceans are often disregarded within the environmental movement despite the fact that they are the key to life on earth and are in a degraded state. Further, Tasmania’s marine environment is utterly unique, with ninety percent of its marine life found nowhere else on earth. Despite the magnificent biodiversity …

This study explores how Uganda’s agricultural sector can be developed in a way that improves the quality of life of smallholder farmers in Katente and Namuyenje parishes in Mukono district, Uganda. Ugandan agricultural production is starved of new sources of knowledge and technology, …

A Habitat And Abundance Study Of Octopus Cyanea In Southwest Madagascar, Michael Belazis

Independent Study Project (ISP) Collection

The increased demand for marine products has fueled a worldwide overexpansion of the fishing industry. Furthermore, the shift of lower-income countries, like Madagascar, from subsistence to market-based cash economies has led to increased fishing pressures on marine resources. Recent commercialization of fisheries in Southwest Madagascar has caused an over-exploitation of octopus in the Toliara region. In an effort to create sustainable octopus fisheries, Blue Ventures, a UK-based NGO, created the world’s first community run Marine Protected Area (MPA) for octopus near Andavadoaka called Velondriake.

Here, the results of an Octopus cyanea habitat study performed near Beheloke, a fishing village on …

Examining Trends In Taste Preferences, Market Demand, And Annual Catch In An Indigenous Marine Turtle Fishery In Southwest Madagascar, Kristin Jones

Independent Study Project (ISP) Collection

The worldwide exploitation of marine turtles has been common throughout human history, turtle products including carapaces for decoration and use, skin for leather, and eggs and meat for consumption. The hunting of marine turtles has long established economic importance among Madagascar's coastal inhabitants and is an activity traditionally associated with integral cultural and spiritual values. Due to overexploitation and a combination of relatively newer threats such as pollution, habitat loss, and incidental fisheries take, however, all marine turtle species in the Indian Ocean are considered to be endangered or critically endangered. Although Madagascar's marine turtles have been legally protected from …

In response to negative attitudes towards the existing biodiversity in the region of Puerto Lopez, Ecuador and as a follow-up of a study conducted in 2006 on the status of Burrowing Owl (Athene cunicularia) populations, through informal interviews and observation, this investigation focuses on how local sentiments towards nature have affected the current status of the Burrowing Owl populations and their habitat. The investigation revealed that in addition to the effects of legends and beliefs, there is an existing lack of knowledge, understanding, and appreciation for the extremely high biodiversity, which has created an evident fear instilled in the people. …

A Reassessment Of Avian Assemblages Along The Lakes Corridor In The Atherton Tablelands, North Queensland, Shaina N. Stewart

Independent Study Project (ISP) Collection

Forest fragmentation is the process by which large areas of continuous forest are replaced by foreign ecosystems that restrict native growth to isolated patches. Biota remaining within these fragmented environments often suffer consequences that stem from reduced forest area. Wildlife corridors—linear patches of habitat that connect remnant fragments—have frequently been proposed to alleviate fragmentation effects by facilitating biotic movement between forest patches. Initiated in 1998, the Lakes Corridor on the Atherton Tablelands in North Queensland, Australia, connects the two formerly isolated sections of Crater Lakes National Park with the goal of promoting wildlife dispersal between them. This study monitored avian …
