Quantitative Reasoning And Sustainability, Corrine H. Taylor Jul 2012

Quantitative Reasoning And Sustainability, Corrine H. Taylor

Numeracy

Quantitative Reasoning and Sustainability have much in common. Both are complex, nuanced concepts with rather long definitions that have evolved over time. Both subjects are “everybody’s business” on college campuses, and must be approached in courses across the curriculum, not merely in one course on QR or in one course on Sustainability. The growing, wider presence of both QR and Sustainability on college campuses is due to their applicability in individuals’ personal, professional, and public lives. Moreover, QR and Sustainability support and enhance each other in and out of the classroom. Sustainability is an important, authentic, relevant context for lessons …

Ecosystem Services: The Economics Debate, Joshua Farley Jul 2012

Ecosystem Services: The Economics Debate, Joshua Farley

College of Agriculture and Life Sciences Faculty Publications

The goal of this paper is to illuminate the debate concerning the economics of ecosystem services. The sustainability debate focuses on whether or not ecosystem services are essential for human welfare and the existence of ecological thresholds. If ecosystem services are essential, then marginal analysis and monetary valuation are inappropriate tools in the vicinity of thresholds. The justice debate focuses on who is entitled to ecosystem services and the ecosystem structure that generates them. Answers to these questions have profound implications for the choice of suitable economic institutions. The efficiency debate concerns both the goals of economic activity and the …


Life Cycle Boundaries And Greenhouse Gas Emissions From Beef Cattle, Quentin M. Dudley Jul 2012

Life Cycle Boundaries And Greenhouse Gas Emissions From Beef Cattle, Quentin M. Dudley

Department of Biological Systems Engineering: Dissertations and Theses

Beef cattle are estimated to directly contribute 26% of U.S. agricultural greenhouse gas (GHG) emissions, and future climate change policy may target reducing these emissions. Life cycle assessment (LCA) of GHG emissions from U.S. feedlot beef cattle was conducted to compare methods of the U.S. Environmental Protection Agency (EPA) with a more complete evaluation of emissions. The inclusion of emissions from crop production for feed, associated land use change, and other minor factors nearly doubled GHG emissions associated with beef feedlots from the EPA Annual Inventory estimate of 1611 kgCO2e hd-1 yr-1 to 3182 ± 167 …


Effects Of Leadership And Trauma On Grassroots Community Development In Post-Conflict/Genocide Societies: A Rwandan Case Study, Bryna C. Ramsey Jul 2012

Effects Of Leadership And Trauma On Grassroots Community Development In Post-Conflict/Genocide Societies: A Rwandan Case Study, Bryna C. Ramsey

Capstone Collection

This research paper is an analysis of a grassroots, agricultural project carried out from 2010 to 2011 in Gitarama Cell, a rural community in Rwanda, East Africa, during my United States Peace Corps Volunteer service (2009-2011). The project began as the Twizere Agriculture Club at Gitarama Primary School. The goal of the club was to increase food security among community members through rabbit and chicken husbandry, and the study of such agriculture techniques as composting, double digging, and the establishment of microgardens.

Despite the acknowledged need for this club, the Twizere Agriculture Club project met multiple constraints that affected its …


Using Life Cycle Assessment Methods To Guide Architectural Decision-Making For Sustainable Prefabricated Modular Buildings, Jeremy Faludi, Michael Lepech, George Loisos Jul 2012

Using Life Cycle Assessment Methods To Guide Architectural Decision-Making For Sustainable Prefabricated Modular Buildings, Jeremy Faludi, Michael Lepech, George Loisos

Dartmouth Scholarship

Within this work, life cycle assessment modeling is used to determine top design priorities and quantitatively inform sustainable design decision-making for a prefabricated modular building. A case-study life-cycle assessment was performed for a 5,000 ft2 prefabricated commercial building constructed in San Francisco, California, and scenario analysis was run examining the life cycle environmental impacts of various energy and material design substitutions, and a structural design change. Results show that even for a highly energy-efficient modular building, the top design priority is still minimizing operational energy impacts, since this strongly dominates the building life cycle's environmental impacts. However, as an …

Genetic Patterns Of Domestication In Pigeonpea (Cajanus Cajan (L.) Millsp.) And Wild Cajanus Relatives, Mulualem T. Kassa, R. Varma Penmetsa, Noelia Carrasquilla-Garcia, Birinchi K. Sarma, Subhojit Datta, Hari D. Upadhyaya, Rajeev K. Varshney, Eric J.B. Von Wettberg, Douglas R. Cook

College of Agriculture and Life Sciences Faculty Publications

Pigeonpea (Cajanus cajan) is an annual or short-lived perennial food legume of acute regional importance, providing significant protein to the human diet in less developed regions of Asia and Africa. Due to its narrow genetic base, pigeonpea improvement is increasingly reliant on introgression of valuable traits from wild forms, a practice that would benefit from knowledge of its domestication history and relationships to wild species. Here we use 752 single nucleotide polymorphisms (SNPs) derived from 670 low copy orthologous genes to clarify the evolutionary history of pigeonpea (79 accessions) and its wild relatives (31 accessions). We identified three well-supported lineages …

Do Anthropogenic Dark Earths Occur In The Interior Of Borneo? Some Initial Observations From East Kalimantan, Douglas Sheil, Imam Basuki, Laura German, Thomas W. Kuyper, Godwin Limberg, Rajindra K. Puri, Bernard Sellato, Meine Van Noordwijk, Eva Wollenberg

Rubenstein School of Environment and Natural Resources Faculty Publications

Anthropogenic soils of the Amazon Basin (Terra Preta, Terra Mulata) reveal that pre-Colombian peoples made lasting improvements in the agricultural potential of nutrient-poor soils. Some have argued that applying similar techniques could improve agriculture over much of the humid tropics, enhancing local livelihoods and food security, while also sequestering large quantities of carbon to mitigate climate change. Here, we present preliminary evidence for Anthropogenic Dark Earths (ADEs) in tropical Asia. Our surveys in East Kalimantan (Indonesian Borneo) identified several sites where soils possess an anthropogenic development and context similar in several respects to the Amazon's ADEs. Similarities include riverside locations, …


Industrial Policy And Renewable Energy: Trade Conflicts, Robert J. Carbaugh, Max St. Brown Jun 2012

Industrial Policy And Renewable Energy: Trade Conflicts, Robert J. Carbaugh, Max St. Brown

All Faculty Scholarship for the College of Business

Governments use industrial policy to promote the development of new industries and the creation and adoption of new technologies. Such policy involves subsidies granted to producers and consumers, usually for the purpose of correcting a market failure. Concerning renewable energies such as wind energy and solar energy, China, the United States, and the European Union provide extensive support to producers and consumers. This support has resulted in trade frictions among these nations. This paper discusses the relationship between industrial policy and trade disputes in renewable energy.

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 …

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 …


System Dynamics Implementation Of A Model Of Population And Resource Dynamics With Adaptation, Takuro Uehara, Yoko Nagase, Wayne Wakeland Jun 2012

System Dynamics Implementation Of A Model Of Population And Resource Dynamics With Adaptation, Takuro Uehara, Yoko Nagase, Wayne Wakeland

Systems Science Faculty Publications and Presentations

We build and analyze a dynamic ecological economic model that incorporates endogenous innovation on input substitutability. The use of the system dynamics method allows us to depart from conventional equilibrium thinking and conduct an out-of-equilibrium (adaptation) analysis. Simulation results show that while improvement in input substitutability will expand an economy, this change alone may not improve sustainability measured by indicators such as utility-per-capita and natural resource stock. It could, however, be possible that in combination with other technological progress, improvement in input substitutability will contribute to sustainable development. Sensitivity analysis also indicates a possible complication with the use of exogenous …

Designing For Future Buildings: Adaptive Resuse As A Strategy For Carbon Neutral Cities, Sheila Conejos, Craig Langston, Jim Smith May 2012

Designing For Future Buildings: Adaptive Resuse As A Strategy For Carbon Neutral Cities, Sheila Conejos, Craig Langston, Jim Smith

Craig Langston

Adapting existing buildings is a viable alternative to demolition and replacement in order to mitigate climate change and global warming. Australian cities with inherent cultural heritage fabric, like Melbourne and Sydney, are actively promoting building adaptive reuse as a strategy that supports their programme for developing carbon-neutral cities. Thus, designing for future buildings with embedded adaptive reuse potential is a useful criterion for sustainability. Building adaptive reuse entails less energy and waste, protects the buildings’ heritage values- its socio-cultural and historic meanings; while giving them a new lease of life. This paper looks into urban conservation-- an interdisciplinary field that …
