Sources Of Nutrient And Fecal Microbe Pollution In Otter Creek, Madison County, Kentucky, Kandice L. Smith, Walter S. Borowski
EKU Faculty and Staff Scholarship
We measured nutrient (nitrate, ammonium, phosphate) and fecal microbe concentrations in surface waters of the Otter Creek watershed, Madison County, Kentucky to access sources of these contaminants. The watershed is approximately 12.5 miles long covering ~169 km2 (41,832 acres). The watershed includes East Fork, West Fork, and Dreaming Creek, all tributaries to the main trunk of Otter Creek. The upper portion of the main trunk and Dreaming Creek drain urban areas of Richmond, but 85% of total watershed area is agricultural land, used mainly for grazing cattle. Rural residential areas and woodlands also occur.
The principle contaminants are nutrients …
Global Fossil Energy Markets And Climate Change Mitigation: An Analysis With Remind, Nico Bauer, Ioanna Mouratiadou, Gunnar Luderer, Lavinia Baumstark, Robert J. Brecha, Ottmar Edenhofer, Elmar Kriegler
Global Fossil Energy Markets And Climate Change Mitigation: An Analysis With Remind, Nico Bauer, Ioanna Mouratiadou, Gunnar Luderer, Lavinia Baumstark, Robert J. Brecha, Ottmar Edenhofer, Elmar Kriegler
Physics Faculty Publications
We analyze the dynamics of global fossil resource markets under different assumptions for the supply of fossil fuel resources, development pathways for energy demand, and climate policy settings. Resource markets, in particular the oil market, are characterized by a large discrepancy between costs of resource extraction and commodity prices on international markets. We explain this observation in terms of (a) the intertemporal scarcity rent, (b) regional price differentials arising from trade and transport costs, (c) heterogeneity and inertia in the extraction sector. These effects are captured by the REMIND model. We use the model to explore economic effects of changes …
Water Access And Security For Mongolian Peri-Urban Communities In The Face Of Climate Change And Development, Heather Cook
Water Access And Security For Mongolian Peri-Urban Communities In The Face Of Climate Change And Development, Heather Cook
Independent Study Project (ISP) Collection
The paper attempts to assess how water access and security in Mongolian ger districts is impacted by the competing forces of climate change and development. The development of Mongolia is, understandably, a priority of the government and much of the populace, as are the impacts of climate change, which are well documented and acknowledged. Furthermore, these processes both have potentially adverse impacts on the overall well being of communities. In the context of water access and security, the need to strike this balance becomes even more acute. These factors can all be seen playing out in the city of Sainshand, …

Mapping The Knowledge Economy Of Medicinal Plants In Northern Madagascar: Information And Resource Flow In Traditional Health Practices, Chanelle Adams
Independent Study Project (ISP) Collection
In the wake of pharmaceutical success with alkaloid compounds found in the Madagascar periwinkle (Catharanthus roseus), there has been increased attention towards identifying medicinal properties in the country’s rich flora. Both native and foreign companies seek profitable use of wild plant species found within Madagascar’s unique biodiversity. Many conservation organizations believe that the world’s forests in biological “hot spots” contain cures unknown to modern science and therefore, their preservation essential.
While the protection of these natural resources is important to Western medicine, it is even more vital for local people who depend on the forest as their primary …
Carbon Can’T Buy Happiness: An Analysis Of Ecological Footprints And Happiness Of University Students In The City Of David, Panama, Samantha Burlager
Carbon Can’T Buy Happiness: An Analysis Of Ecological Footprints And Happiness Of University Students In The City Of David, Panama, Samantha Burlager
Independent Study Project (ISP) Collection
Global climate change is perhaps the most pressing issue our world faces today. Greenhouse gas emissions reductions are urgently needed, however, there is currently a lack of action due to the fear that a reduction in the ecological footprint will lead to a reduction in GDP and happiness levels of a society. Increasing GDP and economic progress are equivocated with increasing happiness and overall well-being of society. However, based on the literature I discuss in this paper, instead of GDP, an objective measurement of happiness is a better indicator of success. In this paper, I investigate the ecological footprints (in …

Towards Respecting Indigenous Rights In Development Policy: The Case Of A Community-Based Forest Management Project In Panama, Benjamin Goodman
Benjamin Goodman
As Latin American countries reach new heights of development, perched on the shoulders of an increasingly globalized economy, their local indigenous communities continue to be the most marginalized and impoverished people in the world. Sustainable development initiatives present themselves as a way to contribute to global economic development, while at the same time, respecting the livelihoods of rural peoples and preserving natural resources for future generations. However, unsustainable exploitation of natural resources continues to threaten the livelihoods and identities of many rural indigenous communities. As the economic, legal and political marginalization of indigenous peoples persists, the inevitable result of these …

Biofouling : A Means Of Aquatic Species Transfer, Anne Bouyssou, Josefin Madjidian
NSBWO
Ships carry seawater in their ballast tanks when they are not fully loaded with cargo, in order to maintain adequate trim, draught and stability, adjust list and limit stresses on the hull. It is now well documented that the water pumped into the ship contains aquatic organisms – which can also sink to the sediments at the bottom of tanks – and that these organisms are thereby transferred from the port of origin to the destination. But it is seldom mentioned that aquatic organisms are also found on the outside of ships, attached on their hulls and appendages, as a …

Juxtaposing Nasa’S Aeronet Aod With Carb Pm Data Over The San Joaquin Valley To Facilitate Multi-Angle Imaging Spectroradiometer (Misr) Pm Pollution Research, John Kanemoto
STAR Program Research Presentations
Airborne particulate matter (PM) has been shown to increase the risk for asthma, chronic bronchitis, cardiopulmonary complications, and respiratory cell membrane damage/infection/leakage. PM levels are currently analyzed from two perspectives: stationary land-based monitoring (LBM) sites and total Aerosol Optical Depth (AOD) atmospheric column measurements. Both perspectives often leave miles of space between measuring locations and will have a continually increasing cost from introducing/maintaining sites. The Multi-angle Imaging SpectroRadiometer (MISR) satellite team hopes to begin investigating/archiving PM levels comprehensively via inputting MISR AOD measurements into a function/model which predicts the amount of ground level PM.
In the future, multivariable spatial correlations …

Surface Complexation Modeling Of Cr(Vi) Absorption On Mineral Assemblages, Ann M. Gilchrist
Surface Complexation Modeling Of Cr(Vi) Absorption On Mineral Assemblages, Ann M. Gilchrist
Masters Theses
Hexavalent chromium (Cr(VI)) is a waste product of many anthropogenic processes. Because it is highly mobile, the improper disposal of Cr(VI) has caused widespread contamination. Because reduction and adsorption reactions may reduce the bioavailability and mobility of Cr(VI) in environmental systems, a better understanding of Cr(VI) adsorption behavior will improve remediation efforts.
Subsurfaces and soils are heterogeneous, however most studies focus on single sorbate/sorbent interactions to develop surface complexation models (SCM) for prediction of heavy metal adsorption. Theoretically, combining the SCMsdeveloped for single sorbate/sorbent systems should yield accurate predictions of adsorption in more complex systems (i.e., the component additivity approach …
Evaluation Of Broiler Litter Heat Production During Windrowing & Nitrogen Based Gas Emission Mitigation Using Biofilter, Min Lei
Graduate Theses and Dissertations
Ammonia emission from animal feeding operations (AFOs) has negative effects on environment and animals' health. Thus measuring and mitigating ammonia emission from AFOs is important for environmental protection. In chapter I, different ammonia measurements were discussed and a mitigation technology- biofilter was represented.
In-house windrowing of built-up litter has been used by broiler producers to reduce pathogen loads and rejuvenate litter for the next flock. When litter is piled up for an extended period during downtime, heat generated by the litter pile can become a substantial heat source due to the metabolism of microorganisms. In chapter II, heat production rates …
Natural Area Stewardship Volunteers: Motivations, Attitudes, Behaviors, Corinne Handelman
Natural Area Stewardship Volunteers: Motivations, Attitudes, Behaviors, Corinne Handelman
Dissertations and Theses
To better understand the value of those who engage in environmental stewardship of natural areas, we studied volunteer steward's motivation to participate, their sustainable behaviors and attitudes toward stewardship-related constructs. Specifically, we designed and conducted a survey of volunteers who work as stewards in urban natural areas in Portland, Oregon. We hypothesize that as volunteer frequency increases: participants will be more motivated to participate for environmental reasons, volunteers will be more likely to feel a strong connection to the stewardship site, participants will be more likely to engage in public pro-environmental behaviors, and their level of environmental literacy will increase. …
