Agricultural Carbon Markets: How Could They Work?, Andrew Havens Mar 2022

Agricultural Carbon Markets: How Could They Work?, Andrew Havens

Honors Program: Senior Projects (Public)

The resurgence of voluntary markets in which consumers can purchase carbon credits generated by agricultural carbon sequestration has brought up many questions for farmers looking to potentially enter the market. Past carbon markets, such as the Chicago Climate Exchange, ended when a recession hit, causing demand for credits to swiftly decline. How can modern voluntary markets face these challenges along with new ones and be successful? This research paper, completed as an undergraduate thesis project at the University of Nebraska-Lincoln, examines the economic and scientific factors behind soil carbon sequestration credits. An extended literature review combined with estimation of a …

Patience As A Predictor For Environmental Attitudes, Carolina Missura Mar 2022

Patience As A Predictor For Environmental Attitudes, Carolina Missura

Undergraduate Economic Review

This paper aims to show the relationship between an individual’s value of patience and the degree to which they exhibit pro-environmental attitudes. My hypothesis is that country-wide patience has a strong impact on an individual’s attitudes towards protecting the environment. I present two methods to address this relationship, each method employs a different variable used to measure environmental attitudes. Given some discrepancies in the results from the first method, the second was the one utilized to reach the conclusion. The paper concludes that there is a positive and significant correlation between patience and environmental attitudes.

Regenerative Tourism Model: Challenges Of Adapting Concepts From Natural Science To Tourism Industry, Asif Hussain, Marie Haley Feb 2022

Regenerative Tourism Model: Challenges Of Adapting Concepts From Natural Science To Tourism Industry, Asif Hussain, Marie Haley

Journal of Sustainability and Resilience

The study proposes a regenerative tourism model. The application of the natural science ideas of regeneration needs to be clarified before the tourism industry can adopt a regenerative tourism model. Without such clarification, there is a high risk of ‘green washing’ and inappropriate adaption of a regenerative model. The borrowing of natural science to industry and its application in social sciences confuse the essence of the true concept of regeneration. In a regenerative agriculture context restoring a holistic system that mimics nature and includes social and economic spheres contributes to improving the whole system. When a social system aims to …

The Rise Of Community-Based Natural Resource Management Strategies As Explained By Transaction Costs, Keely A. Fisher, Marc R. Donnelly, Collin Adams Jan 2022

The Rise Of Community-Based Natural Resource Management Strategies As Explained By Transaction Costs, Keely A. Fisher, Marc R. Donnelly, Collin Adams

Undergraduate Economic Review

Community-based natural resource management (CBNRM) is favored over its predecessor, the fortress approach, for common pool resource (CPR) management. We strive to identify variables associated with successful CBNRM programs, and analyze whether their presence transaction costs can explain the shift in favored conservation strategy. By examining nine case studies of large mammals in Africa, we found that out of eight variables, moderate monitoring and adequate program incentives were the most critical various factors in determining CBNRM program outcomes. Furthermore, these variables, as well as others, contributed to a decrease in transaction costs.

The Long-Term Problem With Electric Vehicle Batteries: A Policy Recommendation To Encourage Advancement For Scalable Recycling Practices, Lauren Fricke Jan 2022

The Long-Term Problem With Electric Vehicle Batteries: A Policy Recommendation To Encourage Advancement For Scalable Recycling Practices, Lauren Fricke

Seattle Journal of Technology, Environmental, & Innovation Law

With the growing popularity of electric vehicles, the demand for lithium ion (Li-ion) batteries, which are the dominant energy source for electric vehicles, are skyrocketing. By default, this means a growing demand for the raw materials needed to manufacture these complex batteries such as lithium, cobalt, and nickel. Economic, environmental, and political supply chain factors bring into question the sustainability of these batteries as a solution to the issues surrounding gasoline powered transportation, creating a need for large scale Li-ion battery recycling. By 2030, 140 million EVs are predicted to be on the road worldwide. In that time, eleven million …

Nanotechnology offers new opportunities for the development of novel materials and strategies that improve technology and industry. This applies especially to agriculture, and our previous field studies have indicated that zinc oxide nanoparticles provide promising nano-fertilizer dispersion in sustainable agriculture. However, little is known about the precise ZnO-NP effects on legumes. Herein, 1 mg·L−1 ZnO-NP spray was dispersed on lentil plants to establish the direct NP effects on lentil production, seed nutritional quality, and stress response under field conditions. Although ZnO-NP exposure positively affected yield, thousand-seed weight and the number of pods per plant, there was no statistically significant …

Blue Growth: A Transitions Approach To Developing Sustainable Pathways, Christina Kelly, Ben Mcateer, Frances Fahy, Liam Carr, Daniel Norton, Desiree Farrell, Rebecca Corless, Stephen Hynes, Zacharoula Kyriazi, Agnès Marhadour, Regis Kalaydjian, Wesley Flannery

Journal of Ocean and Coastal Economics

The sustainable management of Blue Growth is an urgent issue for coastal states. Marine industries have rapidly expanded over the last two decades and this is projected to continue with the European Green Deal and post-COVID economic recovery policies. The intensification of Blue Growth could have adverse socio-ecological implications and must, therefore, be managed in terms of sustainability, natural resource boundaries, and coastal community well-being. Managing Blue Growth in a sustainable manner however, is challenging due to the longstanding inefficiencies and inertia of existing marine governance regimes. Adopting a transitions approach has been advanced as a way of steering regime …

Riders On The Storm: Hurricane Risk And Coastal Insurance And Mitigation Decisions, Harrison Laird, Craig E. Landry, Scott Shonkwiler, Dan Petrolia Jan 2022

Riders On The Storm: Hurricane Risk And Coastal Insurance And Mitigation Decisions, Harrison Laird, Craig E. Landry, Scott Shonkwiler, Dan Petrolia

Journal of Ocean and Coastal Economics

This paper utilizes cross-sectional, household-level, survey data combined with data on subjective risk perceptions and experimentally derived risk preferences to analyze the decision to insure against hurricane losses. Our sample encompasses 670 individuals in five states of the United States Gulf Coast Region (Texas, Louisiana, Mississippi, Alabama, and Florida). This study represents one of the few papers to examine wind insurance empirically and the only study to examine flood insurance, wind insurance, and mitigation behavior contemporaneously. Because these decisions are closely related, we employ a mixed-process regression, which allows for correlated error terms across a random-effects bivariate probit model (flood/wind …

Invited Perspective - Nutritional Needs And Implications For Children In Subsistence Marketplaces, Nagendra Rangavajla Jan 2022

Invited Perspective - Nutritional Needs And Implications For Children In Subsistence Marketplaces, Nagendra Rangavajla

Subsistence Marketplaces

Today, while the number of stunted children is decreasing in all geographies, the progress is not consistent. Moreover, there is an increasing prevalence of overweight and obesity among children and adolescent. Globally, about half of all children under five do not receive essential nutrients, often unnoticed until too late. On the other end of the spectrum, the incidence of overweight and obesity in 5-19 year old has increased from 4% in 1975 to 18% in 2016 1. These trends reflect a ‘triple burden of malnutrition’, a burden that impacts the survival, growth, and development of children, and in turn, …

County Walkability And Small Business Receipts, Talia Perluss Jan 2022

County Walkability And Small Business Receipts, Talia Perluss

Scripps Senior Theses

This thesis explores the correlation between county walkability and small business receipts, as well as other possible demographic variables that could explain the success of small businesses, by using a fixed-effect panel regression model. Using county-level data in the years 2012 and 2017, this paper finds that there is a significant correlation between an increase in walkability and an increase in receipts. When running the fixed-effect regressions, this paper found that there is a moderately high positive correlation between walkability and per capita income, suggesting that the effects of an increase in walkability may also capture the effects of an …

Sustainability In The New England Ski Industry, Sydney E. Gendreau Jan 2022

Sustainability In The New England Ski Industry, Sydney E. Gendreau

Honors Theses and Capstones

The goal of this study is to explore the extent to which sustainable investments are worthwhile for the New England ski industry. Research has shown that the New England ski industry will be greatly impacted by the effects of climate change within the near future. Anthropogenic climate change over the next several decades will cause frequent low snow winters, increases in night time winter temperatures, and overall shorter winters. Detailed economic analysis has shown that low snow and warm winters result in roughly $54 million in lost revenue for the New Hampshire ski industry in the past (Burakowski, Magnusson, 2012). …

“The Real Cost Of Mining: How Digging For Rare Earth Metals Could Pose A Greater Cost Than Evs Can Save”, Brahim Khalil Yatim Jan 2022

“The Real Cost Of Mining: How Digging For Rare Earth Metals Could Pose A Greater Cost Than Evs Can Save”, Brahim Khalil Yatim

Honors Theses and Capstones

The Paris Climate Agreement proposes to have 20% of all road transport vehicles be electric by the year 2030. Implementation of this policy is critical to help obtain a 2 degrees Celsius reduction in the increase of global temperatures by 2030. This paper dives into the true costs of taking on a project that large scale. This study finds that though the benefits of this project would result in a 351,785,600 tons of GHG saved by the electric conversion there are significant environmental and human costs associated with the mining necessary to complete the agreement's goal. With current technologies and …

The Health Effects Of Anthropogenic Pm2.5 Emissions, Andrew Charles Meyer Jan 2022

The Health Effects Of Anthropogenic Pm2.5 Emissions, Andrew Charles Meyer

Honors Theses and Capstones

This study analyzes the health impacts of particulate matter 2.5 (PM2.5), a common anthropogenic pollutant resulting from vehicles, manufacturing, and wood burning. PM2.5 is an emission of particular concern given its small size of roughly 2.5 micrometers, allowing it to stay in the atmosphere for up to 10 days and penetrate the deepest area of the lungs, the alveoli. This penetration can lead to adverse respiratory and cardiovascular health outcomes, and ultimately lead to an increased mortality rate. This study utilizes data from 1,885 counties in the U.S. between 2001 and 2017, and included health outcome, PM2.5 , and demographic …

Climate Trailblazer Or Corporate Giveaway: An Economic And Political Evaluation Of Cap-And-Trade In California, Benjamin Reicher Jan 2022

Climate Trailblazer Or Corporate Giveaway: An Economic And Political Evaluation Of Cap-And-Trade In California, Benjamin Reicher

Pomona Senior Theses

In this thesis, I conduct an economic and political analysis of California’s cap-and-trade program, the leading national (and international) example of a market-based strategy to reduce climate-warming greenhouse gas emissions. I evaluate the program on several economic and political measures of success, especially as contrasted with the performance of various regulatory policies that California also relies on to meet its emissions reduction targets. These regulations exemplify a command and control approach to emissions mitigation as opposed to a market-based approach, and indeed tend to be favored by grassroots activists who may be skeptical about market-friendly policies; my thesis seeks to …

Integrating Carbon Pricing Approaches, Amay Shah Jan 2022

Integrating Carbon Pricing Approaches, Amay Shah

CMC Senior Theses

Concerns about global climate change and its effects have been steadily growing around the world in recent years. The Paris Agreement has laid out ambitious targets for countries to cut their emissions in order to limit global warming to 1.5 degrees and to achieve net zero emissions by 2050. Carbon pricing mechanisms are an inventive instrument that can help achieve these emissions reductions by placing a price on greenhouse gas emissions, creating incentives for organizations to reduce their emissions. These mechanisms can also help enable the transfers from wealthy nations to developing nations that will be essential for ensuring a …

In My Backyard: Bioregional Communities As A Climate Mitigation Strategy, Zoe Johnston Jan 2022

In My Backyard: Bioregional Communities As A Climate Mitigation Strategy, Zoe Johnston

Capstone Showcase

The urgency of the climate crisis requires an immediate revisioning of our society in order to mitigate the worst environmental consequences. This paper explores one possible climate mitigation strategy, bioregionalism, a theoretical vision of re-localizing economies and defining their reach by natural boundaries (Curtis 2003; Cato 2011). This idea of relocalization emerges from an understanding that globalized capitalism has exacerbated, if not engendered, the climate crisis. Local communities represent an alternative method of organizing in which people are more directly connected to the land that they live on. One major critique of bioregionalism, made by Albo (2007) and Hahnel (2007), …

The Nexus Of Climate Change, Biodiversity, And Food Security: A Brazil Case Study, Andrew M. Berger Jan 2022

The Nexus Of Climate Change, Biodiversity, And Food Security: A Brazil Case Study, Andrew M. Berger

Dissertations and Theses

What is referred to as climate change today is the rapid warming of the climate, largely from human actions, and the effects that come with that warming. One study published by the United States Department of Agriculture (USDA) in 2021 argues that, “human-induced emissions of greenhouse gases have caused increases in global average temperatures, changes in precipitation timing and intensity, rising sea levels, and many other changes.” A Food and Agriculture Organization (FAO) study found that when looking at the number of countries exposed to climate extremes in five year periods from 2000 to 2020, the number of countries “exposed …

Migration And The Quality Of American Cities, Chase Mendell Jan 2022

Migration And The Quality Of American Cities, Chase Mendell

CMC Senior Theses

Across the United States, cities are expanding. It is the role of the city leaders to promote policies that benefit both current and incoming residents. While these policies have intended results, the realized benefits and damages are challenging to define because they are the result of individual choices and the unique characteristics of the city. As a result, policymakers need to consider a complex web of factors such as employment, taxation, housing, mobility, and environmental quality. This thesis seeks to analyze these overlapping factors to discuss how policymakers can increase well-being while mitigating potential harms.

Rural Development In Papua New Guinea: Mining, Logging, Agriculture, And Alternatives, Tj Askew Jan 2022

Rural Development In Papua New Guinea: Mining, Logging, Agriculture, And Alternatives, Tj Askew

CMC Senior Theses

This thesis examines multiple approaches to providing rural, indigenous Papuans with improved social services and economic opportunities. Rural Papuans, who make up 80 percent of the population, face below average rates of nutrition, education, disease, crime, and other quality of life indicators. Due to location, land use rights, lack of infrastructure, and minimal access to economic markets, the PNG government has struggled to provide rural communities with basic social services. Historically, the development of resource extraction projects such as mining, logging, and agriculture have been the main strategies used to improve the livelihood of rural Papuans, with limited success. This …

Marx, Critical Theory, And The Treadmill Of Production Of Value: Why Environmental Sociology Needs A Critique Of Capital, Alex Stoner Jan 2022

Marx, Critical Theory, And The Treadmill Of Production Of Value: Why Environmental Sociology Needs A Critique Of Capital, Alex Stoner

Journal Articles

This chapter explores the domestication of Marx’s critique of political economy within Marxist-oriented environmental sociology, and treadmill of production (ToP) theory, in particular. The aim is to explicate the theoretical resources for a rigorous critique of capital-induced planetary degradation. Shortcomings of ToP theory pertaining to the conceptualization of capital and value are identified. The reasons for these shortcomings, including how they might be addressed, are elaborated by reconsidering key aspects of Marx’s critical theory of modern capitalist society. The chapter contributes to current discussions in both critical theory and environmental sociology by demonstrating the continued relevance of Marx’s critical theory …

Invited Perspective - Engaging Aspirations To Nurture Communities, Kentaro Toyama Jan 2022

Invited Perspective - Engaging Aspirations To Nurture Communities, Kentaro Toyama

Subsistence Marketplaces

For subsistence communities, the question is whether aspirations can be applied to motivate behavior that is, on the one hand consistent with people’s aspirations, but which might otherwise be difficult to elicit. Could poorer households be encouraged to save, to spend more on their children’s education, or to act against unhealthy social norms? A couple of examples suggest this is not only possible, but highly successful in contexts where other appeals fail.
