The Deep Roots Of Vietnamese Tea: Culture, Production And Prospects For Development, Robert Wenner Oct 2011

The Deep Roots Of Vietnamese Tea: Culture, Production And Prospects For Development, Robert Wenner

Independent Study Project (ISP) Collection

Vietnam is at a critical stage in its development. If policy is properly managed the country’s future is incredibly bright as the middle class grows and standards of living continue to rise throughout the country. Agriculture will play a key role in future development as nearly 70 percent of the population participates directly in agricultural work. Each crop that is produced and exported in Vietnam will play a different and integral part in development as the face of agriculture changes with Vietnam’s increased global presence. This research looks specifically at tea production in Vietnam through the lens of agricultural development. …

Animal Enrichment Strategies For Promoting Natural Behaviors In Captive Populations Of Tasmanian Devils (Sarcophilus Harrisii), Tierney O’Neal Oct 2011

Animal Enrichment Strategies For Promoting Natural Behaviors In Captive Populations Of Tasmanian Devils (Sarcophilus Harrisii), Tierney O’Neal

Independent Study Project (ISP) Collection

The population of Tasmanian devils (Sarcophilus harrisii) is in rapid decline due to Devil Facial Tumour Disease, and insurance populations have been created in captivity for potential future introduction into the wild. Many problems can arise within captive animal populations including loss of natural behaviors, and development of negative stereotypical (i.e. pacing) behaviors. These issues can decrease ecological fitness, potentially jeopardizing success of introductions of animals into the wild. By providing captive animals with enrichment, natural behaviors can be increased, and stereotypical behaviors can be decreased. Enrichment is defined as an activity or item that promotes the mental and physical …


Effects Of Coral Stressing On The Feeding Preferences Of The Coral Predator, Acanthaster Planci, Harriet Booth Oct 2011

Effects Of Coral Stressing On The Feeding Preferences Of The Coral Predator, Acanthaster Planci, Harriet Booth

Independent Study Project (ISP) Collection

Coral predators have always been a natural occurrence on coral reefs, but recent studies have begun to focus on the feeding preferences of these predators in relation to bleached and damaged corals. The recent mass bleaching events, mainly resulting from factors of climate change, have motivated researchers to study the effects of predation on the affected corals to determine the extent of harm these large-scale disturbances may be causing to reefs. This study examined how coral stressing affects the feeding preferences of Acanthaster planci, a coral-feeding starfish that has been known to cause widespread damage to coral reefs, especially during …


Presence Of The Dingo (Canis Lupus Dingo) On Risk Sensitive Foraging Of Small Mammals In Forest Ecosystems, Amanda Lu Oct 2011

Presence Of The Dingo (Canis Lupus Dingo) On Risk Sensitive Foraging Of Small Mammals In Forest Ecosystems, Amanda Lu

Independent Study Project (ISP) Collection

Trophic regulation of mesopredators through top order predators can have profound effects on ecosystem community and diversity. In the absence of top predators, invasive mesopredators exert strong selective pressures on native prey and can alter prey foraging behavior. When foraging in the presence of predators, prey must weigh predation risk against food gain. To examine the indirect impacts of dingo baiting on risk sensitive foraging in forests, we measured differences in giving up densities (GUDs) and surveyed local populations of mesopredators and mammals. We hypothesized that in baited areas, mesopredators would be more abundant and prey would perceive greater predation …


Reconstructing The Farm: Life Stories Of Dutch Female Farmers, Marisa Turesky Oct 2011

Reconstructing The Farm: Life Stories Of Dutch Female Farmers, Marisa Turesky

Independent Study Project (ISP) Collection

My research asks: what are the lived experiences of female farmers within the hegemonic construction of the Dutch farmer and how have their roles shifted through time? Popular culture has implanted stereotypes that most female farmers are uneducated, low-class individuals but the six women whom I interviewed present life stories that complicate this. How did these women come into their roles as farmers? Once they became such entrepreneurs, what were their challenges in a potentially male-dominated profession? While there has been extensive research on rural women’s historical roles in farming, I analyze the personal experiences of a small sample of …


“ Gimme Samoa That!”: The Changing Diet In Samoa, Dana Melby Oct 2011

“ Gimme Samoa That!”: The Changing Diet In Samoa, Dana Melby

Independent Study Project (ISP) Collection

With globalization and Samoa’s entrance into the global economy imported and processed foods, which are high in fat, sugar, and sodium, are increasingly available for consumption. Diet transition, the change in diet from one high in local and traditional foods to one high in imported processed foods, began in Samoa post-World War II, however, the rate of diet change has increased rapidly in the past three decades. The change in diet has led to increased prevalence of obesity, other risk factors, and non-communicable diseases. Non-communicable diseases (NCDs) include cardiovascular disease (CVD), diabetes, and cancer. This study looks at what factors …

The Cerro Hojas-Jaboncillo, located in Central Manabí, Ecuador, is a Patrimonial site that, in addition to containing the ruins of an ancient culture, is home to a species of mammal endemic to the tumbesian eco-region. Currently listed by the ‘LibroRojo de los mamíferos del Ecuador’ as vulnerable, the Sechuran Fox (Lycalopexsechurae) is a nocturnal and solitary animal, of a medium size, that is rarely seen due to its elusive behavior. This species is the focus of this investigation, which seeks to gain an understanding of the plants and animals that the Sechuran Fox requires for food, the home …


A Study Of Sponge Aquaculture In Jambiani: Is Shallow Farming Feasible?, Sarah Friday Oct 2011

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, …


The Influence Of Family Structure On Women’S Role In Agriculture In Two Distinct Societies Of Southwest China, Audrey Boochever Oct 2011

The Influence Of Family Structure On Women’S Role In Agriculture In Two Distinct Societies Of Southwest China, Audrey Boochever

Independent Study Project (ISP) Collection

A popular idiom in China is nángēngnǚzhì: men plow, women weave. This ubiquitous saying reflects traditional gender roles in agriculture throughout Chinese history, how men traditionally were in charge of the land, while women took care of tasks within the home, such as making clothes for the family. The cloth used to weave usually came from cotton.[1] In this regard, both men and women have always had roles to play in agriculture in China, but from different facets.

While recognizing that women and men have played different roles in Chinese agriculture, my field study examines the role of …

Independent Study Project (ISP) Collection

Through the recent years, the Cuenca-Molleturo-Naranjal highway that cuts through the Cajas national park has been the object of much environmental research. In particular, the effects of the highway on the territorial distribution of the local avifauna—that includes many endemic and endangered species—has been a very important subject of study for the conservationists and the park managers. The following study is supplementary to the work of the University of Azuay and the University of Stoneybrook in New York. Here, we analyze how the highway may influence the sex ratios of one of the most commonly found specie—Phrygilus unicolor. Using observations …


Exploring Marine Conservation Efforts In Tasmania: An Internship With Ocean Planet, Lauren Markram Oct 2011

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 …


What Is The Value Of A Sea Turtle?: A Case Study Of The Conservation Ethics Of Sea Turtle Fishermen In The Caribbean Coast Of Nicaragua, Alicia Conte Oct 2011

What Is The Value Of A Sea Turtle?: A Case Study Of The Conservation Ethics Of Sea Turtle Fishermen In The Caribbean Coast Of Nicaragua, Alicia Conte

Independent Study Project (ISP) Collection

The sea turtle populations on the Caribbean Coast of Nicaragua have dramatically decreased as a result of human use and consumption. All species of sea turtles are endangered and at risk of extinction. This is an environmental issue because if sea turtles go extinct, many other plants and animals in marine ecosystems will be negatively impacted by this loss, and the environment will be drastically altered. This is also problematic for locals who depend on this resource for food and as a source of income. Conservation efforts have been initiated by an international NGO, the Wildlife Conservation Society (WCS); however, …


Nomadic Knowledge Of The Yak: A Case Study In The Khangai Mountains, Mongolia, Jesse Geary Apr 2011

Nomadic Knowledge Of The Yak: A Case Study In The Khangai Mountains, Mongolia, Jesse Geary

Independent Study Project (ISP) Collection

It is extremely important to probe and preserve the knowledge of nomadic herders of Mongolia. There is no formal piece of literature that dictates how these clever humans survive. Their lifestyle requires a vast skill set spanning from construction knowledge, to navigational skills, to a deep understanding of their animals. One attains this knowledge through years of observation, listening, and attempting to mimic their parents. In this way, knowledge is passed on from one generation to the next. Investigating herder’s knowledge of the yak provides a window into the animal husbandry practices of Mongolian nomads. The herders in the central …

Growing Farmers’ Markets: Measuring The Competitiveness Of The Byron Farmers’ Market With Other Local Food Sources, Audrey Gross

Independent Study Project (ISP) Collection

Farmers’ markets are growing across the world at an exponential rate. However, there is little research that challenges the competitiveness of these farmers’ markets in competing with other food distribution locations, including supermarkets and local food stores. The following report focuses on using the principles of perfect competition to evaluate the competitiveness of the Byron Farmers’ Market with other local food sources in Byron Bay, NSW.

Data was collected through 120 consumer surveys (60 from the Farmers’ Market, 30 from Woolworths, and 30 from local food stores: Santos, Fundamentals, and Green Garage), 31 stallholder surveys from the Farmers’ Market, price …


Validating The Culture Of Agriculture: Farmers Groups And Organic Agriculture Mitigating Rural To Urban Migration In Bhutan, Emma Dosch Apr 2011

Validating The Culture Of Agriculture: Farmers Groups And Organic Agriculture Mitigating Rural To Urban Migration In Bhutan, Emma Dosch

Independent Study Project (ISP) Collection

Agricultural occupations make up the largest proportion of Bhutan’s workforce. Over the past two decades the occupation has shrunk from 90% to 65% of Bhutan’s employment. The younger generation of Bhutan’s rural population is seeking livelihood opportunities in urban areas, leaving farms with labor shortages. The movement may compromise the identity and sustainability of Bhutan’s rural population and undermine the nation’s goals of Gross National Happiness (GNH) directed policy. Initiatives to retain and legitimize agricultural livelihoods are emerging inside and outside of government policy. Existing efforts are models of ways to reconnect educated individuals with the needs and values of …

Predators Of Enashiva: A Survey Of Occurrence & Distribution, Adrienne Fisk Bowles

Independent Study Project (ISP) Collection

This study was conducted during a period of 16 days (April 10 to April 26, 2011) at the Enashiva Nature Refuge in Northern Tanzania. It was a modified repeat study, using the same methodologies of a mammal survey conducted in November 2009, however this study only focused on occurrence and distribution of predators in the highest trophic level and accounted for reptile and birds, in addition to mammals. Based upon the findings of the November 2009 study, it was hypothesized that the woodland would have the highest predator species richness. This hypothesis was supported by the data; the woodland habitat …


A Habitat And Abundance Study Of Octopus Cyanea In Southwest Madagascar, Michael Belazis Apr 2011

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 Apr 2011

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 …

The issue of food security is complex. By analyzing the relationship between international, national and local society, one can better contextualize food security issues. Using an embedded research design (with a qualitative leaning) supported by quantitative data, research is conducted via surveys, interviews and focus groups. This research design was chosen to offset limited sample sizes with quantitative data to strengthen findings. Research findings were cross analyzed to identify three emergent themes. The three cross-cutting themes identified and analyzed are: Thai citizenship, employment and chemical pesticide use (chemical pesticide use did not arise among Burmese refugees and is only applicable …


A Framework For Monitoring Local And Regional Food Systems, Heather Victoria Davis Jan 2011

A Framework For Monitoring Local And Regional Food Systems, Heather Victoria Davis

Capstone Collection

The US food system has been experiencing gradual, yet significant, changes in recent years - with many people recognizing that conventional approaches are not only unsustainable, but also detrimental. As an alternative paradigm, the development of local food systems has been flourishing because of the benefits they bring to us: more local control over our food; supporting the local economy and entrepreneurs; healthier food options; fewer “food miles” and the related benefits of lowered use of petroleum; stronger community bonds; job creation for our rural communities; more gentle on the environment; and a more secure food system overall. Monitoring the …
