The Solid Waste Management System Of Jaipur: An Overview And Analysis, Laura Olivier

Independent Study Project (ISP) Collection

Jaipur’s rapid development has resulted in its infrastructure lagging behind population and industrial growth, which is especially evident in the unsightly and unsanitary piles of solid waste (garbage) on the roads. This project took a broad system approach to understand Jaipur’s solid waste management system. It investigated how the system is carried out, some obstacles to its success, and the role of Public Private Partnerships (PPPs). The findings indicate that there is a multiple-tiered hierarchical system. The system involves a formal sector comprised of female and male sweepers, permanent and impermanent workers, and an informal sector of ragpickers and door-todoor …

As Rivers Run Dry: A Study Of Global Freshwater Scarcity And Its Implications For Socio-Economic Development, Sophia Wenzlau

Independent Study Project (ISP) Collection

Water scarcity is a serious problem—without adequate supplies of clean freshwater, there cannot be life. The direct and indirect costs of water scarcity are huge, including poor public health, gender inequality, and acute restrictions for economic development. Currently, around 20 percent of the global population lacks access to safe drinking water and 2.4 billion people do not have access to adequate sanitation facilities (UNEP Brief, 1). About 1.8 million people—most of them children less than five years old—die every year due to water-borne diseases from fecal pollution—the equivalent of about 15 killer tsunamis each year or 12 Boeing 747 crashes …

“Mangra”- Exploring The Organization Of An Environmental Education Curriculum In A Village Equipped For Sustainable Development, Abigail Phillips Oct 2009

“Mangra”- Exploring The Organization Of An Environmental Education Curriculum In A Village Equipped For Sustainable Development, Abigail Phillips

Independent Study Project (ISP) Collection

The rapid growth of urban centers in the last century has resulted in obvious social stratification and neglect of the natural environment. Not only is the gap between rich and poor increasing, but the resources that supply urban consumption and community development are increasingly depleted without due recognition. These issues are successfully addressed in some communities by drawing example from more traditional practices of ecological management, such as water conservation and local food production. Environmental education could be utilized to aid in the relief of social issues and environmental degradation if the curriculum is specialized for each community’s circumstance. Children …

For a period of three weeks I spent my days wandering the streets of Maun, talking to lodge owners, restaurants, local bars, and private waste collectors investigating the ways in which beverage cans are reused, recycled, and disposed of in Maun. Ultimately I wanted to uncover the story of the beverage can in the village of Maun. Throughout my investigation I sought to answer three important questions: how, why and by who are beverage cans recycled, how do villagers reuse beverage cans, and what are the major barriers preventing more widespread reuse and recycling of beverage cans. I conducted my …


Environmental Conscience And Comportment Of Youth In Dakar, Elizabeth Van Brocklin Oct 2009

Environmental Conscience And Comportment Of Youth In Dakar, Elizabeth Van Brocklin

Independent Study Project (ISP) Collection

The natural environment is in a state of crisis in Dakar, in Senegal, in Africa and throughout the world. Humans are the primary contributors to environmental degradation, as their activities place stress on natural ecosystems, and this stress is often most acute in the urban setting. Dakar is one major West African city where inhabitants are particularly neglectful and disrespectful of their communal environment, illustrated by the oppressive presence of mismanaged waste that pollutes the public streets. Based on the hypothesis that the general population was either unaware or misinformed of the actual state of the environment, I aimed to …

Corallivorous Reef Fishes As Potential Vectors Of Coral Disease Based On A Study Of Dietary Preferences, Tanya Rogers Oct 2008

Corallivorous Reef Fishes As Potential Vectors Of Coral Disease Based On A Study Of Dietary Preferences, Tanya Rogers

Independent Study Project (ISP) Collection

The prevalence of coral disease appears to be increasing worldwide, although little is known about how these diseases are transmitted between coral colonies. To examine whether corallivorous fishes could potentially act as disease vectors, this study examined whether and which fish species feed on diseased coral, and whether these fishes actively target diseased coral sections. Branches of Acropora muricata with brown band disease were filmed in the field, and bites taken by fishes on different sections of the coral (live tissue, tissue margin, disease band, dead skeleton, and algae) were recorded. For each fish species, electivity indices were calculated for …

Desarrollo Turístico Y Sustentabilidad: Caso Villa Pehuenia Y La Comunidad Mapuche Puel, Sasha Shahidi

Independent Study Project (ISP) Collection

With limited resources and overpopulation on a global level, sustainable development is the only way that human beings will be able to survive on this earth. The problem is that the dominant model of development stresses the importance of economic profits in the short term and far too often exploits natural resources and less powerful cultural groups. This creates dangerous long-term affects as natural resources and indigenous cultures that depend on them continue to disappear with no plan, or possibility, to replace them. Sustainability seeks the least negative impacts possible on the natural environment and indigenous cultures in order to …

The role of mercury and cyanide in gold mining has become a hot topic in Mongolia in the past few years. In the past few months, the government has launched a crackdown on the illegal use of these chemicals in response to the contamination of Khongor soum’s drinking water which resulted from an illegal mining operation. However, there are many more sites throughout the country that are in need of cleaning as a result of the illegal use of these chemicals by small companies as well as individual miners.

This paper examines the role of a variety of different views …


Decision Modeling: Why Farmers Do Or Do Not Convert To Organic Farming, Ryan Locke Apr 2006

Decision Modeling: Why Farmers Do Or Do Not Convert To Organic Farming, Ryan Locke

Independent Study Project (ISP) Collection

This study examines why farmers in Northern New South Wales, Australia do or do not convert to organic farming from conventional farming practices. Organic agriculture provides a production alternative that may be environmentally and nutritionally beneficial. Because the structural settings of economy and society influence decision-making on an individual basis at the farm level, discussions of policy must consider why farmers do, or do not, convert to organic farming. Ultimately, the successfulness of a policy depends on the effectiveness of motivating individual action. A hierarchical decision tree was created using ethnographic decision tree modeling. Elimination criteria, motivational criteria, and constraints …

Environmental Sustainability And The Traditional Tibetan Home, Katherine Shrader

Independent Study Project (ISP) Collection

In Tibetan Buddhism, the srivatsa, or glorious endless knot, reminds one of the truth of reality. Six right-angled, intertwined strands flow endlessly together, each one connected to the other, each one giving form to the next. So flows reality. Looking past the illusion of isolation, the endless knot illustrates the interdependence and mutual cooperation that runs the world.

No event, no living being has the ability to stand by itself, completely unaffected and unaffecting. All phenomena are intertwined. Every human action, however big or small, impacts the world in some way. The endless knot unveils the truth of reality so …
