Arsenic Contamination In Groundwater In Vietnam: An Overview And Analysis Of The Historical, Cultural, Economic, And Political Parameters In The Success Of Various Mitigation Options, Thuy M. Ly

Pomona Senior Theses

Although arsenic is naturally present in the environment, 99% of human exposure to arsenic is through ingestion. Throughout history, arsenic is known as “the king of poisons”; it is mutagenic, carcinogenic, and teratogenic. Even in smaller concentrations, it accumulates in the body and takes decades before any physical symptoms of arsenic poisoning shows. According to the World Health Organization (WHO), the safe concentration of arsenic in drinking water is 10 µg/L. However, this limit is often times ignored until it is decades too late and people begin showing symptoms of having been poisoned.

This is the current situation for Vietnam, …

Mathematical Modeling Of Fluid Spills In Hydraulically Fractured Well Sites, Oluwafemi Michael Taiwo

Graduate Theses and Dissertations

Improved drilling technology and favorable energy prices have contributed to the rapid pace at which the exploitation of unconventional natural gas is taking place across the United States. As a natural gas well is being drilled, reserve pits are constructed to hold the drilling fluids and other materials returned from the drilling process. These reserve pits can fail, and when they do, plant and animal life of the surrounding area may be adversely affected. This project develops a screening tool for a suitable location for a reserve pit. This work will be a critical piece of the Infrastructure Placement Analysis …

Fishermen, Politics, And Participation: An Ethnographic Examination Of Commercial Fisheries Management In St. Croix, U.S. Virgin Islands, Cynthia Grace-Mccaskey

USF Tampa Graduate Theses and Dissertations

Currently, there is widespread debate regarding the overall status of the world's fisheries, with some researchers projecting their total collapse in only a few decades, and others concluding the situation is not quite as bleak. Additional debates include what strategies should be used to manage fisheries at various scales, and further research is needed to determine which strategies are most appropriate for use in particular situations and locales, as context is critical.

Recently, prominent common pool resources scholars have expressed the need for ethnographic approaches to studying resource management institutions in order to move beyond the current focus of simply …

Assessing The Viability Of Desalination For Rural Water Supply In Chwaka, Zanzibar, Roy Yu, Daniele Packard

Independent Study Project (ISP) Collection

Zanzibar has been struggling with water scarcity issues over the last few decades due to an increase in consumption on the island and a deterioration of existing supply infrastructure. Poor distribution has affected rural communities most, due to their absence of tourism development, which has gone hand in hand with infrastructure establishment. Foreign aid has begun to address the issue by investing in alternative forms of water supply. On November 15, 2011, The Minister for Housing, Lands, and Water, Ali Juma Shamhuna inaugurated the Mörk desalin® RO 100 SW desalination machine, a solar and wind powered desalination unit in Chwaka …

A Meta-Analysis Of Alternative Water Sources, Katie Colton

Honors Projects in History and Social Sciences

Roughly one half of the Earth’s population suffers from shortage or lack of clean water. While many innovations and products have been created to address this Global Water Crisis, no comparisons have been done as to which innovations and products are the best overall choice for philanthropic investment. The crisis can be broken down into three specific crises including the transportation crisis, the access crisis, and the sanitation crisis. The study examined fifteen innovations and products, targeted to address the three crises to determine which innovation in each group is the overall smart investment. Pulse tool was used to create …

A Conceptual Model To Facilitate Amphibian Conservation In The Northern Great Plains, David M. Mushet, Ned H. Euliss Jr., Craig A. Stockwell

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

As pressures on agricultural landscapes to meet worldwide resource needs increase, amphibian populations face numerous threats including habitat destruction, chemical contaminants, disease outbreaks, wetland sedimentation, and synergistic effects of these perturbations. To facilitate conservation planning, we developed a conceptual model depicting elements critical for amphibian conservation in the northern Great Plains. First, we linked upland, wetland, and landscape features to specific ecological attributes. Ecological attributes included adult survival; reproduction and survival to metamorphosis; and successful dispersal and recolonization. Second, we linked ecosystem drivers, ecosystem stressors, and ecological effects of the region to each ecological attribute. Lastly, we summarized information on …

Water And Energy Balance Response Of A Riparian Wetland To The Removal Of Phragmites Australis, Phillip Mykleby

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Vegetation and climate both play integral roles in water availability, particularly for arid to semi-arid regions. Changes in these variables can lead to extreme shortages in water for regions that rely on water for crop irrigation (i.e., the Great Plains). The objective of this study is to evaluate the impacts of vegetation on water availability in the Republican River basin in central Nebraska. Decreases in streamflow have been observed in the river basin for many years and, as a result, an invasive riparian plant species (Phragmites australis) is being removed in an effort to reduce evapotranspiration and reclaim …

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 …

Organic Cacao Farming In Transamazônica: An Assessment Of Sustainable Livelihood Development, Stephanie Cesario

Independent Study Project (ISP) Collection

Cacao production is growing in the newly opened forest frontiers of the Trans- Amazonian Highway in central Pará, the second biggest producer region in Brazil. This region has recently witnessed the growth of some of the first organic cocoa cooperatives in the country, initially formed in 2006. Cacao presents a unique option for agricultural livelihoods, because grows well in its native habitat under the shade of Amazon forest species, and there is a growing market demand for cocoa. This study aims to assess the organic certification’s effects on tree diversity and cocoa production in this Amazon frontier, together indicating sustainable …

Régulations De L’Usage Et De La Possession De Terre: Exploration De L'Efficacité Des Règles Officielles Concernant La Gestion De Terre Et Perceptions Des Lois Par Les Habitants D’Andranomena Dans La Région Menabe, Ben Armstrong

Independent Study Project (ISP) Collection

Autour d’Andranomena, un village qui se trouve près de Morondava dans la Région Menabe, il y a encore des terres non cultivées couvertes d’herbes sauvages ou de forets. Mais avec l’accroissement de la population dû au taux de natalité et de l’immigration, il y a de plus en plus de pressions pour trouver de la terre nouvelle.

Cette recherche de terrain se passe avec deux processus parallèles: le premier est la demande de titres domaniaux auprès de l’Etat effectuée par l’intéressé et le second est la validation de la possession de terre avec la connaissance locale de la personne qui …

Fourteen Years Of Sustainable Charcoal: The Case Of Ankitsakalaninaomby, Dan Raudonis

Independent Study Project (ISP) Collection

All over the world, different sources of energy are harnessed by populations looking to fulfill their needs, be it electricity, heating, or cooking. In Madagascar, fuel wood and wood charcoal provide the bulk of daily energy needs – for over 85% of the population they are the only available sources of domestic energy (GREEN-Mad 6). These two sources provide a cheap alternative to other fuels such as natural gas, which can be more than three times as expensive as charcoal (GREEN-Mad 51). In an impoverished country such as Madagascar, where 90% of the population live on less than two US …

Implications For Old-Field Restoration: Diversity And Abundance Of Arbuscular Mycorrhizal Fungi In Soils Of Restored York Gum (Eucalyptus Loxophleba Subsp. Loxophleba) Sites Vs. Remnants., Jessica Wong

Independent Study Project (ISP) Collection

Arbuscular mycorrhizal fungi (AMF) may be critical to the restoration of ecosystem function in old-fields. Whether the diversity of the plant community is promoted by the AMF community or is the driving force of AMF diversity is unknown. We investigated two questions in the context of old-field restoration in southwestern Australia: 1) Does restoration of the plant community achieve the restoration of AMF and 2) Is AMF species diversity and abundance influenced by the plant species composition? Our study sites were located in the Ridgefield Experiment in the University of Western Australia’s “Future Farm”. Soil samples were collected from beneath …

The State Of Artisanal Fisheries In Southern Unguja: Governance, Conservation And Community, Nathanial Colbert-Sangree

Independent Study Project (ISP) Collection

Fifty-one fishermen in the coastal villages of Kizimkazi Dimbani and Jambiani were interviewed to discover the current state of fishing in these areas. Each area has its own Village Fishermen Committees and those committees were also a subject of interest, interviewing their members as well as Fishery Department Officials to gain an understanding of how the committees function and their success. Results of fishermen interviews revealed a large number of differences between Kizimkazi Dimbani and Jambiani. Village Fishermen Committees were well attended by participants in both villages and seem to function as strong institutions within the communities studied. Kizimkazi Dimbani …

New Approaches To The Green Revolution: Successes, Failures And New Rice For Africa, Maia S. Woluchem

Independent Study Project (ISP) Collection

The nature of worldwide food insecurity is staggering, with thirteen percent of the world’s population currently malnourished. The situation is particularly dire in Sub- Saharan Africa, where 265 million people face hunger daily, with 30 to 50 million dying yearly. Solutions to the problem are often unsustainable, save a select few. Once such attempt, coined the Green Revolution, garnered both praise and notoriety through its relatively successful transformation of Southeast Asia in the 1960’s. Aimed at increasing food production, the project focused on small-holder farmers and their acquisition of more productive inputs such as high-yield seeds, fertilizers and pesticides. African …

Control Biologico De La Broca Del Cafe (Hypothenemus Hampei) En La Valle De Vilcabamba, Loja, Ecuador. Una Comparacion De Huertas Usando El Hongo Beauveria Bassiana, María Mugnani

Independent Study Project (ISP) Collection

Today coffee has become one of the most popular beverages in the world and is cultivated in many countries. However, in recent years many areas of production, for example in the province of Loja, Ecuador in the valley of Vilcabamba, many are experiencing a threat in the form of a small Coleoptera species. Hypothenemus hampei, also known as la broca de café, passes the majority of its life cycle within the coffee berries and in the process of reproduction and colonization it destroys the bean that makes the beverage. This destruction of the bean no only affects the consumer, …

West Of Eden: Resource Wars And Nature-Cultures In The American West, Scout Calvert

University of Nebraska-Lincoln Libraries: Faculty Publications

The richness and variety of the western landscape is what is at stake in hot political contests for the resources of the West: much of this public land is available to economic activity, including for mining, grazing, logging, and recreation. These uses threaten to outpace the land’s ability to renew these resources along with others, like air and water. Now in the first decade of the millennium with a new environmental awareness emerging partly from media coverage of global warming and peak oil, The American West at Risk offers a wide-ranging look at the degradation of the environment in the …

Global Monthly Water Scarcity: Blue Water Footprints Versus Blue Water Availability, Arjen Y. Hoekstra, Mesfin Mekonnen, Ashok K. Chapagain, Ruth E. Mathews, Brian D. Richter

Daugherty Water for Food Global Institute: Faculty Publications

Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by considering monthly rather than annual values. We analyzed 405 river basins for the period 1996–2005. In 201 basins with 2.67 billion inhabitants there was severe water scarcity during at least one month of the year. The ecological and economic consequences of increasing …

The Water Footprint Of Humanity, Arjen Y. Hoekstra, Mesfin Mekonnen

Daugherty Water for Food Global Institute: Faculty Publications

This study quantifies and maps the water footprint (WF) of humanity at a high spatial resolution. It reports on consumptive use of rainwater (green WF) and ground and surface water (blue WF) and volumes of water polluted (gray WF). Water footprints are estimated per nation from both a production and consumption perspective. International virtual water flows are estimated based on trade in agricultural and industrial commodities. The global annual average WF in the period 1996–2005 was 9,087 Gm3 ∕y (74% green, 11% blue, 15% gray). Agricultural production contributes 92%. About one-fifth of the global WF relates to production for export. …

Ecosystem Services: The Making Of A Metaphor We Live (?) By, Richard B. Norgaard

Systems Science Friday Noon Seminar Series

What started as a humble metaphor to help us think about our relation to nature has become integral to how we are addressing the future of humanity and the course of biological evolution. The metaphor of nature as a stock that provides a flow of services is insufficient for the difficulties we are in or the task ahead. Indeed, combined with the mistaken presumption that we can analyze a global problem within a partial equilibrium economic framework and reach a new economy project-by-project without major institutional change, the simplicity of the stock-flow framework blinds us to the complexity of the …

The Steady-State Economy As A Solution To The World’S Problems: A Theoretical Examination Of The Greatest Environmental Problem Facing Human Society, Brianna L. Besch

The Macalester Review

This paper is a theoretical exploration of the questioning, if you were given a magic power to solve one, and only one, of the worlds problem outlined by a classic environmental author, which would you solve, and why? While the field of environmental studies is relatively new, since the publishing of Malthus’ An Essay on the Principles of Population environmental scholars have been debating what should be considered the greatest environmental problem facing humanity. This paper explains how the creation of a steady-state economy to replace our current economic system, as described by Herman Daly, offers a holistic solution to …

Agriculture Futures: Potential Rural Land Uses On The Palusplain, Rodney Safstrom, Nicolyn Short Dr

Resource management technical reports

The purpose of this project was to identify agricultural land use options and opportunities within the Serpentine–Jarrahdale and Murray Shires, with particular focus on the Palusplain wetland section. The report will contribute to the Department of Planning’s natural resource management plan for the region and guide development of regional and local planning strategies. Historically, the Palusplain was a slowly moving, interconnected, seasonal wetland system with areas of higher ground. Extensive clearing and drainage occurred in the late 1800s through to the mid-1900s to facilitate agriculture; however, agriculture has been found to be a major contributor of nutrients to the system. …

Scotts Bluff National Monument, Plant Community Resource Brief, Isabel Ashton, Mike Prowatzke

United States National Park Service: Publications

2011 Monitoring Status

Overview

In 2011, the first year of vegetation monitoring by the Northern Great Plains Network Inventory and Monitoring staff at Scotts Bluff National Monument, efforts resulted in the documentation of 79 plant species. This was the lowest number of species among parks sampled in 2011. Graminoid (grass and grass-like plant) species accounted for only 21 (27%) of the total species, but graminoid cover was much higher than that of any other plant type. Forbs were much more diverse, but did not provide as much foliar cover.

The 5 most abundant native non-graminoids were winterfat (Krascheninnikovia lanata …
