Combating Suburban Sprawl In The Capital District: An Outline For Regional Sustainable Development, Andrew J. Cahill Jun 2012

Combating Suburban Sprawl In The Capital District: An Outline For Regional Sustainable Development, Andrew J. Cahill

Honors Theses

Urban centers in America have commonly been plagued by high rates of pollution, decaying infrastructure, and the overall image of being undesirable places to live. Beginning in the second half of the twentieth century, masses of people vacated the cities that they called home, for literally greener pastures, settling in outlying, low-density living areas that became known as the suburbs. Suburbanization has particularly impacted the land use pattern in the Capital District of New York State, as countless suburbs developed away from the region’s urban centers of Albany, Schenectady and Troy. Recently people have moved back into the Capital District’s …


Modeling Biofuel Production In Southern Pine Forests: The Effects On Soil Properties, Brittany L. Oakes Jun 2012

Modeling Biofuel Production In Southern Pine Forests: The Effects On Soil Properties, Brittany L. Oakes

Honors Theses

From consuming energy alone in 2009, the United States ranked second as a carbon emitter at 5,425 million metric tons annually; China was the leader at 7,706 million metric tons and India placed third at 1,591 million metric tons (EIA, 2010). Yet in 2009, the U.S. consumed more electricity than both China and India and was the leading importer of electricity (EIA, 2010). Incorporating more domestic sources of renewable energy can simultaneously alleviate two issues: mitigating climate change catastrophes and significantly reduce our dependence on foreign markets for electricity and other forms of energy. Additionally, evidence of dwindling international oil …


The Politics Of Rsfs: An Antidote To Reversing The Resource Curse In Latin America?, Sarah Gagnon Jun 2012

The Politics Of Rsfs: An Antidote To Reversing The Resource Curse In Latin America?, Sarah Gagnon

Honors Theses

Over the past three decades, the world has become highly globalized. As such, most countries around the world depend on exports for a large portion of their national income. However, some countries’ dependency on exports is extreme, especially those that heavily rely on natural resource commodities. Despite the natural resource wealth that these commodities grant countries, due to the instability of global prices and the intensive focus of the resource extraction industry, scholars have theorized this type of dependency as a “resource curse.” The resource curse is a paradox where countries that are so rich in natural resources have not …

Environmental Risk Explored Through Oil Spills And Hydraulic Fracturing: Attempting Environmental Protection Through Policy, Samantha M. Guidon Jun 2012

Environmental Risk Explored Through Oil Spills And Hydraulic Fracturing: Attempting Environmental Protection Through Policy, Samantha M. Guidon

Honors Theses

History demonstrates the dangers of ignoring the environmental risks that correspond to resource extraction, especially in precarious locations. This project analyzed three cases: (1) the 1989 Exxon Valdez oil spill, (2) the 2010 Deepwater Horizon oil spill, and (3) the current question of hydraulic fracturing in New York’s Marcellus Shale. The case studies assessed whether policies for protecting the environment from the risks of human activity have improved and whether such policies can be made both economically efficient and environmentally less risky. While the Exxon Valdez case demonstrated the dangers of not planning for disaster, it did result in the …


Putting The Wind At Our Backs: Assessing U.S. Potential For 20% Wind Energy By 2030, Kevin T. Harnett Jun 2012

Putting The Wind At Our Backs: Assessing U.S. Potential For 20% Wind Energy By 2030, Kevin T. Harnett

Honors Theses

The discussion surrounding the future of energy, particularly in the United States, has gained significant momentum in recent years for an obvious reason — it’s daunting. Our dependence on fossil fuels has positioned our nation in an undesirable predicament with a questionable future. With the associated consequences, principally Climate Change, it is essential that energy be addressed as a primary national concern. Renewables need to flip the switch.

Documenting The Anthropogenic Impact On Ballston Lake New York From A Short Core Using Stable Isotopes Of Carbon And Nitrogen And Trace Metals, Taylor S. Labrecque

Honors Theses

Ballston Lake occupies a portion of an avulsed channel of the Mohawk River between Schenectady and Saratoga Springs, New York. The lake is about 5 km long, generally less than 200m wide, ~8-15m deep, dimictic, with a catchment basin area of ~22km2. Long cores (>8 m) indicate that the lake formed ~13,000 cal yr BP. This study was undertaken to document recent environmental change recorded in the upper portion of sediment in Ballston Lake. Three sediment cores ~40 cm long were acquired from ~8 m water depth at the north end of Ballston Lake (42°57.101’N, 73°51.066’W), and were analyzed …


Anti-Nuclear Activism And The Past, Present And Future Of United States Nuclear Energy Policy, Isabel C. Zellweger Jun 2012

Anti-Nuclear Activism And The Past, Present And Future Of United States Nuclear Energy Policy, Isabel C. Zellweger

Honors Theses

Nuclear power has had a long and controversial history leading people to have many different views on the topic. Even though nuclear power does provide the nation with a significant portion of its electricity, many still fear its risks, especially after the events at Fukushima last spring. This thesis explores how public opinion, current events, and anti-nuclear activism have shaped nuclear power in America today. After reviewing the literature on nuclear energy in the United States, I discuss the past and current state of United States nuclear energy policy, and then describe changing American attitudes toward nuclear power over time. …


Net Co2 Reduction Analysis For A Wind Farm, Darren Del Dotto Jun 2012

Net Co2 Reduction Analysis For A Wind Farm, Darren Del Dotto

Honors Theses

The purpose of this study was to determine the net CO2 reduction benefit that can be achieved by using wind instead of coal power. Coal power has a significantly higher rate of CO2 emissions than wind generation, but wind power generation has a significant amount of embodied energy. The goal of this study is to determine the net carbon reduction benefit that can be achieved using wind power after accounting for factors such as embodied energy in materials and construction.


The Effect Of Phosphite On Mycorrhiza Formation In American Chestnut (Castanea Dentata), Matthew T. Perkins May 2012

The Effect Of Phosphite On Mycorrhiza Formation In American Chestnut (Castanea Dentata), Matthew T. Perkins

Honors Theses

One of the primary hindrances to Castanea dentata restoration in the Southeast is the root rot disease caused by the fungus-like microorganism Phytophthora cinnamomi. Root rot can be combated by the application of mono- and di-potassium salts of phosphorous acid, which are marketed as phosphite fungicides. Despite its value in preventing infection by P. cinnamomi it is also thought that phosphite may impede root colonization by beneficial, ectomycorrhizal fungi. I hypothesized that plants given a routine application of phosphite will display fewer mycorrhizas in the root tips than those plants that were not treated with potassium phosphite. Therefore I attempted …


Evaluating Bucknell's Waste Stream, Hallie S. Kennan Apr 2012

Evaluating Bucknell's Waste Stream, Hallie S. Kennan

Honors Theses

This thesis examines three questions regarding the content of Bucknell University‟s waste stream and the contributors to campus recycling and solid waste disposal. The first asks, “What does Bucknell‟s waste stream consist of?” To answer this question, I designed a campus-wide waste audit procedure that sampled one dumpster from each of the eleven „activity‟ types on campus in order to better understand Bucknell‟s waste composition. The audit was implemented during the Fall semester of the 2011-2012 school year. The waste from each dumpster was sorted into several recyclable and non-recyclable categories and then weighed individually. Results showed the Bison and …


From Pond To Pump: Microalgae As A Feedstock For Biodiesel, Anna H. Leavitt Jan 2012

From Pond To Pump: Microalgae As A Feedstock For Biodiesel, Anna H. Leavitt

Honors Theses

The global reliance on fossil fuels is an unsustainable practice that has led to the depletion of finite resources and the accumulation of greenhouse gases in the atmosphere, leading to global climate change (Demirbas 2010). Transportation accounts for about a third of carbon dioxide (CO2) emissions in the United States. Demand for oil continues to increase and resources are becoming more uncertain. Increased production of renewable fuels such as biofuels can help ease the dependence on fossil fuels. Although interest and production in biofuels has been increasing in the past decade, current feedstocks do not meet efficiency needs and some …


Cameras, Satellites, And Surveys: A Multi-Platform Approach To Monitoring Lake Conservation Behavior, Daniel D. Homeier Jan 2012

Cameras, Satellites, And Surveys: A Multi-Platform Approach To Monitoring Lake Conservation Behavior, Daniel D. Homeier

Honors Theses

Shoreline buffers are essential to maintaining lake water quality and there are numerous methods for their assessment. There is uncertainty in the benefits and drawbacks of different shoreline buffer assessment methods. In this study I explore three methods of remotely assessing shoreline buffers in the Belgrade Lakes Region of Maine: household surveys, geotagged shoreline photos, and satellite imagery. By comparing these three methods I will evaluate their accuracy and applicable scale when used to assess the presence and quality of shoreline buffers.

I used both parametric and non-parametric analysis to (1) evaluate the relative accuracy of 154 household surveys in …
