Is There Value In The Valuation Of Environmental Regulations?, Gage B. Hornung

CMC Senior Theses

Cost-benefit analysis has become one of the principal components in the review process of environmental regulation. However, the valuation of environmental regulation poses a unique challenge, as the benefits of the rules issued by the Environmental Protection Agency are often non-monetized, whereas the costs are more readily monetized. To give weight to the very real but non-monetized benefits of environmental regulation, methodologies have been developed to mark the price of the non-marketable. Still, many would claim that certain benefits of environmental regulations are not captured in cost-benefit analysis or are undervalued by the practice. Hence, while the practice is promoted …

The Past And Future Of Migration, Poverty, And Small-Scale Agriculture In Mexico, Kimberly Zamora Delgado

CMC Senior Theses

The conflated pattern between poverty, rurality, and indigeneity in Mexico signifies drastic inequality between populations. Poor, rural communities often do not receive as much public services, infrastructure improvements, and employment opportunities as urban areas, which causes out-migration into the cities. Some of the few jobs available in rural areas are in the agriculture sector, either through small-scale subsistence farming or seasonal employment on a large-scale farm. Historically, certain wealthy states such as Sinaloa, Michoacán, and Sonora received greater support to up-scale into modernized agriculture, which made them into the largest agro-exporters. On the other hand, poor states with greater indigenous …

A Hot Conflict Growing Ever Hotter: How Climate Change Provokes Instances Of Violence In South Sudan, Madison Menard

CMC Senior Theses

In South Sudan, people are not engaging in violent altercations because of climate change. People are not deciding to kill other people because the average temperature of the world has risen 1 degree celsius, or harming their neighbor because of irregular rain patterns. Alas the link from climate change to violence is not as direct as that. Rather, climate change has played a non-direct role in the South Sudanese conflict. Within the political marketplace it has subtly altered conditions which later spark or intensify outbreaks of violence. Climate change in this sense should be viewed as a stressor of sorts …

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

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 …

Community Development Supporting Ecological Conversion, As Identified In Laudato Si’: On Care For Our Common Home, Anne Jennings

Theses

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 …

Voices Of The Often Unheard: The Environmental Impacts Of Catastrophic Wildfire Events On Individuals With Developmental Disabilities, Mary Madison Mckenzie

Graduate Student Theses, Dissertations, & Professional Papers

The Thomas Fire for a time was the largest wildfire in California history, burning 281,893 acres and destroying 1,063 structures. Within three years, the August Complex Fire, at 1,032,649 acres, almost quadrupled that record. Climate related disasters such as these have impelled social science researchers to heed calls for a paradigm shift in understanding the risks climate change poses to the social world, in particular, disaster risks for vulnerable groups. Existing research tends to focus on disasters such as hurricanes, featuring risks for vulnerable populations by race, class, and/or individuals with disabilities in general, but not for individuals with developmental …

Keeping What You Sow: Intellectual Property Rights For Plant Breeders And Seed Growers, Paulina B. Jenney

Graduate Student Theses, Dissertations, & Professional Papers

Over the last 150 years, the food system in the present-day United States has undergone a transformational restructuring, from a diversified, decentralized, network of farmers and seed growers, to one in which the majority of crop production is controlled by a few industrial corporations. The consolidation of power has been under-girded by the application of intellectual property rights (IPR)—especially utility patents—to plant varieties and genetic traits, which are leveraged to exclude small-scale seed growers from accessing quality germplasm. Patents and restrictive licensing agreements recapitulate colonial structures by appropriating common and traditionally community-held resources for profit, and by creating reliance on …

Settler Colonialism And White Environmentalism In The 'Uba, Aleena Church

Cal Poly Humboldt theses and projects

Settler colonialism continues to shape present injustices of Indigenous Peoples. The settlers of Nevada County do not recognize the historical past of colonialism and how it has changed the Nisenan Tribes relationship to these lands/waters. Or how colonization still thrives in Nevada County through settler relationships with these lands/waters. Settler colonialism is ongoing, it is not an event that happened during the gold rush. I use the South 'Uba River (South Yuba River) as an example for how settler colonialism continues to perpetuate violence and genocide amongst the Nisenan Peoples. As we, settlers, occupy these lands and waters we must …

Puffins, The Charismatic Clowns Of The Sea: Examining The Relationship Between Community Identity And The Social Construction Of Animals, Megan Henry Tuennerman

Senior Independent Study Theses

This study analyzes the factors, internal and external, that affect the relationship between community identity and the social construction of animals, and the ways in which that social construction impacts the environment. Studied through the lens of the relationship between Atlantic Puffins and the human communities they live near, these questions situate our understanding of human societies as within, as opposed to above, the environment. Without this perspective, enacting environmental protections across the globe is ineffective. The study was conducted using ethnographic methods, including 11 formal interviews with community members and experts, along with observations in Iceland and Canada. Results …
