Evaluating Columbus, Georgia, Tree Canopy Interactions With Air Pollutants Using High Spectral Imagery And Portable Pm Sensors, Kristin N. Youngquist

Theses and Dissertations

Trees provide environmental, economic, and social advantages in urban areas. Knowing the extent and location of tree canopy in a municipality is an important step in quantifying these benefits. Spatial and temporal tree canopy analysis was performed for the city of Columbus, Georgia, by categorizing the National Agriculture Imagery Program (NAIP) aerial imagery for 2005, 2010 and 2015 into tree versus non-tree land cover type using unsupervised classification procedures. Air pollution removal rates from the i-Tree program were applied to this evaluation providing an estimate of the city’s tree air quality benefits. The city’s canopy overall has remained steady at …

Nanotechnology has significant economic, health, and environmental benefits, including renewable energy and innovative environmental solutions. Manufactured nanoparticles have been incorporated into new materials and products because of their novel or enhanced properties. These very same properties also have prompted concerns about the potential environmental and human health hazard and risk posed by the manufactured nanomaterials. Appropriate risk management responses require the development of models capable of predicting the environmental and human health effects of the nanomaterials. Development of predictive models has been hampered by a lack of information concerning the environmental fate, behavior and effects of manufactured nanoparticles. The United …

Incentive Compatible Climate Change Mitigation: Moving Beyond The Pledge And Review Model, Gabriel Weil

William & Mary Environmental Law and Policy Review

Climate change represents a global commons problem, where individuals, businesses, and nation-states all lack sufficient incentives to reduce their greenhouse gas emissions to levels consistent with meeting their collectively agreed upon mitigation goals. The current “pledge and review” paradigm for global climate change mitigation, which many see as a major breakthrough, relies primarily on moral pressure, reputational incentives, and global public opinion to foster cooperation on mitigation efforts over and above those driven by maximization of narrow conceptions of national interests. Given the scale of the emissions reductions required to meet stated mitigation goals, the substantial economic costs of deep …

Independent Study Project (ISP) Collection

Plastic debris is a global threat to the natural environment. The accumulation of plastic debris has resulted in the destruction of marine habitat as well as a threat to marine wildlife. Single use plastics, including plastics associated with single use food and beverage containers are contributing to a considerable amount of debris and other litter in the world’s oceans. As awareness of this issue spreads, both large corporations and small businesses are beginning to transition to plastic alternatives for their single use beverage containers. In Byron Bay, Australia, an area of increasing environmental awareness, businesses are beginning to reduce single …

Policy Communication And The Influence Of Agricultural Communities On Karst Landscapes: A Case Study In Phong Nha-Kẻ Bàng National Park, Vietnam, Elizabeth Willenbrink

Masters Theses & Specialist Projects

Karst landscapes are vulnerable to human influence, especially agricultural practices. The interconnectedness between surface activities and subsurface environments make karst landscapes particularly susceptible to soil erosion and water contamination. The likelihood of these two phenomena happening increases when agricultural intensification, irrigation, or fertilizer application occurs. This situation arises frequently in Vietnam, where 18% of the country is karst terrain and 60% of the population depends on agriculture for their livelihoods (Farming First 2009). In order to mitigate the negative consequences of agriculture on karst landscapes, effective implementation of policy to regulate human activities and increased communication of these policies to …

Let’S Talk Takataka: Impacts Of Plastic In The Stone Town Harbor Area, Zanzibar, Cj O’Brien

Independent Study Project (ISP) Collection

Plastic pollution has become an anthropogenic crisis worldwide. In the Stone Town Harbor area in particular, consumerism, population growth, tourism and a deficient municipal waste management system contribute to alarming amounts of mismanaged plastic that enter the ocean. This is devastating for the diverse marine ecosystem that provides valuable resources to its flora and fauna and to it human inhabitants. In this study, micro-plastic at the sea surface as well as plastic on coastal beaches was quantified to determine the effects of plastic pollution in the area by use of a standard plankton net methodology. This study contributed to the …

A Disappearing Island: An Impact Assessment Of Coastal Erosion On The Mnemba Island House Reef, Zanzibar, Kat Grellman

Independent Study Project (ISP) Collection

Sedimentation is one of the greatest threats reefs face today due to climate changeinduced sea level rise. Mnemba Island has experienced rampant coastal erosion as a combined result of global processes and local anthropogenic impacts, which has in turn caused severe reef degradation. The house reef was surveyed over a 3-week period to determine the amount of sediment deposited on the reef and the impact of this sedimentation on coral reef health. Sediment traps were deployed to measure the sediment flux rate. The line-intercept transect method was used to measure the benthos cover of the reef and point-transect method was …

A Comparative Tree Survey Of Disturbed And Primary Forest Areas: Ngezi-Vumawimbi Nature Forest Reserve, Pemba Island, Skyler Smith

Independent Study Project (ISP) Collection

Off the coast of Tanzania, in East Africa, the island of Pemba was once covered in pristine forest despite having a small, agriculturally-based human population. Beginning around 1840, however, the island began to be deforested on a large scale for colonial plantations of cash crops such as cloves and rubber as well as for small-scale farms and firewood. Ngezi-Vumawimbi Nature Forest Reserve covers about 1,440 hectares and is all that remains of these once vast forests. The reserve was officially designated in 1957 but timber extraction and exploitation there continued until the late 1980s. In the early 1970s, a large …

Cuando La Vida Era Tranquila: Land Use And Livelihood Changes Following The Construction Of The Chan 75 Dam In Nance Del Risco, Bocas Del Toro, Patrick Mckenzie

Independent Study Project (ISP) Collection

The Ngobe are Panama’s most populous indigenous group. While the Ngobe that live in the comarca have land and resource rights, those that live immediately outside of it do not. This issue has been exacerbated by the creation of Palo Seco Forest Reserve which has removed all land rights from the Ngobe living within it. In order to meet its growing demand for energy, Panama is expanding its hydroelectric sector. One such hydroelectric dam built by AES is Chan 75. However, Chan 75 has had a controversial history, especially regarding its treatment of the Ngobe people of the corregimiento Nance …

Geography Faculty Publications and Presentations

For cities in sub-Saharan Africa a 1.5 °C increase in global temperature will bring forward the urgency of meeting basic needs in sanitation, drinking water and land-tenure, and underlying governance weaknesses. The challenges of climate sensitive management are exacerbated by rapid population growth, deep and persistent poverty, a trend for resolving risk through relocation (often forced), and emerging new risks, often multi-hazard, for example heat stroke made worse by air pollution. Orienting risk management towards a developmental agenda can help. Transition is constrained by fragmented governance, donor priorities and inadequate monitoring of hazards, vulnerability and impacts. Opportunities arise where data …

The Role Of Nutrition In Influencing Mechanisms Involved In Environmentally Mediated Diseases, Bernhard Hennig, Michael C. Petriello, Mary V. Gamble, Young-Joon Surh, Laura A. Kresty, Norbert Frank, Nuchanart Rangkadilok, Mathuros Ruchirawat, William A. Suk

Superfund Research Center Faculty Publications

Human exposure to environmental contaminants such as persistent chlorinated organics, heavy metals, pesticides, phthalates, flame retardants, electronic waste and airborne pollutants around the world, and especially in Southeast Asian regions, are significant and require urgent attention. Given this widespread contamination and abundance of such toxins as persistent organic pollutants (POPs) in the ecosystem, it is unlikely that remediation alone will be sufficient to address the health impacts associated with this exposure. Furthermore, we must assume that the impact on health of some of these contaminants results in populations with extraordinary vulnerabilities to disease risks. Further exacerbating risk; infectious diseases, poverty …

High-Resolution Water Footprints Of Production Of The United States

Daugherty Water for Food Global Institute: Faculty Publications

The United States is the largest producer of goods and services in the world. Rainfall, surface water supplies, and groundwater aquifers represent a fundamental input to economic production. Despite the importance of water resources to economic activity, we do not have consistent information on water use for specific locations and economic sectors. A national, spatially detailed database of water use by sector would provide insight into U.S. utilization and dependence on water resources for economic production. To this end, we calculate the water footprint of over 500 food, energy, mining, services, and manufacturing industries and goods produced in the United …

Reduction In Needlestick Injuries Using A Novel Package Of Interventions, Kamal Thakor Patel

USF Tampa Graduate Theses and Dissertations

In 2015 Dr. Pratiksha Vaghela started the “Stop Poking Me” campaign which was aimed at curbing the increase in the number of needlesticks at the James A. Haley Veteran Affairs Hospital (JAHVA). The data for needlesticks was collected by the Occupational Medicine Clinic (OMC) between Oct 2013 and Oct 2016. We then obtained the original data from Dr. Vaghela’s project and compared the data to assess whether the new implementations have truly decreased the number of needlesticks. There was a 23.6% reduction in the number of needlesticks between 2013 and 2016 and even more importantly a 60.1% reduction between 2015 …

Radiological Decontamination In The Urban Environment Utilizing An Irreversible Wash-Aid Recovery System, Keith A. Sanders

Theses and Dissertations

The radioactive fallout from the Fukushima Daiichi nuclear reactors accident and the ongoing threat of nuclear or radioactive terrorism have forced the need for urban radiological decontamination into the forefront. Many of the established decontamination techniques are not ideally suited for the urban milieu. One of the keys to maximize the effectiveness of long-term remediation and recovery in the urban environment is immediate mitigation within a few days of the incident and before a rain event. The Integrated Wash-Aid, Treatment, and Emergency Reuse System (IWATERS) provides a potentially safe and effective method for early responders and remediation teams to perform …

Sensitivity Analyses For Simulating Pesticide Impacts On Honey Bee Colonies, A. Carmen Kuan, Gloria Degrandi-Hoffman, Robert J. Curry, Kristina V. Garber, Andrew R. Kanarek, Marcia N. Snyder, Kurt L. Wolfe, S. Thomas Purucker

United States Environmental Protection Agency: Publications

We employ Monte Carlo simulation and sensitivity analysis techniques to describe the population dynamics of pesticide exposure to a honey bee colony using the VarroaPop+Pesticide model. Simulations are performed of hive population trajectories with and without pesticide exposure to determine the effects of weather, queen strength, foraging activity, colony resources, and Varroa populations on colony growth and survival. The daily resolution of the model allows us to conditionally identify sensitivity metrics. Simulations indicate queen strength and forager lifespan are consistent, critical inputs for colony dynamics in both the control and exposed conditions. Adult contact toxicity, application rate and nectar load …

Nutrient Export From A Proximal Intermittent Stream Draining Eku Meadowbrook Farm, Madison County, Kentucky, James Scott Winter, Walter S. Borowski, Jonathan M. Malzone

EKU Faculty and Staff Scholarship

Agricultural activities contribute significant amounts of nutrients that contaminate surface and subsurface water. Eastern Kentucky University (EKU) Meadowbrook Farm (Madison County, Kentucky) seeks to decrease its export of nutrients to Muddy Creek using sequestration techniques. The first step in the overall process is to determine nutrient export at present, before sequestration efforts take place. Here we estimate the export of phosphate, nitrate, and ammonium during Tropical Storm Cindy (July 22 to 24, 2017) from a proximal, intermittent stream, named the BRC. This stream drains a representative portion the Farm, receiving water from a dairy complex, pasture, and cropland.

Nutrient Contamination From An Agricultural Non-Point Source And Its Mitigation: A Case Study Of Eku Meadowbrook Farm, Madison County, Kentucky, Walter S. Borowski, Reid E. Buskirk, James Scott Winter, Jonathan Malzone Dr.

EKU Faculty and Staff Scholarship

Non-point sources are now responsible for most nutrient contamination in surface water and groundwater, leading to eutrophication and decreased water quality. Because of fertilizer use and animal husbandry, agricultural areas are prime sources for nutrient contamination. Consequently, it is advisable to mitigate entry of nutrients into watersheds from agricultural runoff and groundwater flow. Eastern Kentucky University (EKU) Meadowbrook Farm (Madison County, Kentucky) seeks to decrease its export of nutrients to Muddy Creek, which is tributary of the Kentucky River. To demonstrate the efficacy of any sequestration strategies, nutrient export must be measured both before and after sequestration efforts are implemented. …
