Urban Sprawl And Residential Carbon Emissions: Evidence From Indonesia And The Philippines, Yi Jiang, Taylor Lathrop, Alexander D. Rothenberg, Yao Wang

Center for Policy Research

This paper studies how neighborhood density affects residential carbon emissions, using detailed data from Indonesia and the Philippines. To address simultaneity, we instrument density with soil characteristics, and to address sorting, we control for community averages of observed characteristics. Unlike cities in developed countries, we find that density is positively correlated with residential energy use. After controlling for sorting, we find a precise null relationship between density and residential carbon emissions. Our results suggest that policies to control urban sprawl may not be successful in reducing residential carbon emissions in developing country cities.

When Words Flow Like Water: How The Enbridge Line 3 Pipeline Environmental Impact Statement Failed To Prevent Hydrogeologic Harm In Minnesota, Carly Gutzmann

Journal of Earth and Life Science

For the aquifers of Minnesota, the environmental impact statement (EIS) was a promise of protection that never left the page. An environmental impact statement is meant to be an aid in the decision making process in order to ensure that projects consider potential environmental harms that may occur. However, they are often used instead as another regulatory box to check, rather than as active considerations when planning. As such, a project plan can be flawed from the start—if project developers only consider environmental impacts after they have already put considerable time, effort, and funding into their project as-is, they may …

Localized Air Pollution Impacts From Data Centers In Northern Virginia, Damian Pitt, Ivan Suen, Ellie Plisko

Institute for Sustainable Energy and Environment Publications and Presentations

This report examins the extent of air pollution emissions resulting from the use of backup generators at data centers in Northern Virginia, including both actual current emissions and potential future emissions, and how those emissions totals compare to other sources of air pollution in the Northern Virginia region. It also examines how exposure to data center emissions correlates with demographic characteristics such as race, income, and education.

We while the air pollution emissions from individual data centers is minor, the collective impact from the 100+ such facilities in the Northern Virginia region is significant. Notably, the cumulative emissions exposure in …

Parks Under Pressure: Policy Threats And Advocacy Coalition Resistance In 2025, Rachel Supnick

CMC Senior Theses

This thesis examines the 2025 policy changes affecting the National Park Service (NPS) and their implications for the agency’s mission and advocacy coalition. Historically a bipartisan and widely trusted agency, the NPS has evolved from a conservation-focused mandate into a complex institution balancing environmental protection, recreation, scientific research, and cultural interpretation. Recent policy actions represent not only operational disruption but an unprecedented politicization of the Park Service, reflecting a shift toward centralized executive control. These changes have constrained the agency’s ability to fulfill its mission and placed it within broader ideological conflicts over land use, historical interpretation, and federal authority. …

The Evolution Of California Wildfire Governance Through State Bills, Regulations, And Executive Actions, Cassandra Dawn Blevins

History and Political Science | Senior Theses

California faces an escalating wildfire crisis, driven by climate change, drought, and development in fire-prone areas. Despite decades of scientific research on wildfire behavior and risk reduction, catastrophic fires since 2017 raise a critical question: to what extent have California state laws and policies kept up with the intensifying wildfire crisis? Existing scholarship provides extensive insight into wildfire ecology, land-use planning, fuel management, and community resilience, yet it lacks a comprehensive evaluation of whether California’s legislative, regulatory, and executive actions have adapted in a coordinated and evidence-informed manner. In particular, the literature offers limited analysis of how state laws integrate …

Public Perception Of Environmental Contamination And Its Implications For Fish And Community Health In West Bengal, India, Libia Hazra

Dissertations, Master's Theses and Master's Reports

In West Bengal, India, the highest fish-consuming state in the country, fish are woven into everyday life, including ceremonies of birth and marriage, prayers offered during harvesting and the cultural memory of communities whose identities are inseparable from aquatic life. However, the rivers, wetlands, and ponds that sustain these fish-human relationships are increasingly threatened by environmental contamination resulting from industrial discharge, agricultural runoff, and inadequate environmental management. Understanding how communities perceive these environmental changes is essential for developing effective conservation and public health strategies.

In collaboration between the Indian Institute of Technology (ITT) Kharagpur, India, and Michigan Technological University (USA), …

Good Food In The Neighborhood: Localizing Nutritious Food Access, Joseph Pool

Honors Program Theses

Given contemporary changes to federal budget priorities and recent challenges to federal food access funding, this research explores the potential benefits of entrusting state-level and municipal-level policymakers with food access policy. More specifically, this research suggests that “localizing” food access has the unique benefit of not just addressing the affordability of food, but the physical accessibility of it. As observed in the previous literature and expounded upon here, food provisioning requires consideration of nutrition, physical accessibility, and financial affordability. Programs that only address one of these priorities fail to adequately help people receive the food they need. Through policy analysis …

Educational Inequality In Health Insurance Coverage Before And After The Affordable Care Act, Madelaine R. Adamich

Journal of Earth and Life Science

Health insurance and health care accessibility have historically been ongoing issues within the United States. Two key factors associated with the likelihood of an individual being insured are educational attainment and income. The 2010 Affordable Care Act (ACA), which has been the largest overhaul of health care in the US to date, aimed to reduce disparities in health insurance coverage and health care accessibility. My research analyzes the extent to which the ACA succeeded in reducing disparities related to educational attainment. To examine the ACA’s effects, I utilize the US Census Bureau’s American Community Survey data from 2008 and 2015 …

Indigenous Land Seizure & Environmental Injustice: Impacts Of Settler Colonialism, Lydia Moorman

Journal of Earth and Life Science

The fields of conservation and environmentalism prioritize ecosystem health, yet both emerged from western frameworks that displaced and criminalized Indigenous land stewardship. The idealization of “pristine wilderness” narratives served to justify the removal of Indigenous peoples from their homelands and erased millennia of sustainable land stewardship that had maintained ecological balance long before western conservation existed. These narratives not only misrepresented Indigenous relationship with land but also constructed a false dichotomy between humans and nature that positioned Indigenous presence as a threat rather than a source of ecological knowledge. Simultaneously, anthropogenic expansion; such as pipelines, mining, railroads, and other extractive …

Powering The Machine, Draining The Planet: Whether U.S. Environmental Law Is Equipped To Regulate The Energy And Water Demands Of Ai Data Centers, Michael Marcu

Journal of Earth and Life Science

Artificial intelligence (AI) data centers have become one of the United States' fastest-growing and least-regulated sources of environmental stress. In 2024 alone, U.S. data centers consumed 183 terawatt-hours (TWh) of electricity more than the entire nation of Pakistan and consumed an estimated 17 billion gallons of water (IEA, 2025; Berkeley Lab, 2024). By 2030, electricity demand from these facilities is projected to reach 426 TWh, a 133% increase in six years (Pew Research Center, 2025). This paper examines whether the existing U.S. environmental regulatory framework put by the National Environmental Policy Act (NEPA), the Clean Water Act (CWA), and the …

Applying Transfer Learning For Street-Scale Nuisance Flood Forecasting In Coastal-Urban Environments, Binata Roy, Jonathan L. Goodall, Diana Mcspadden, Chetan Kumar, Steven Goldenberg, Yidi Wang, Malachi Schram

Data Science Faculty Publications

An important challenge with Machine Learning (ML) is its transferability; that is, whether an ML model trained on one set of data can be applied to a second set of data without requiring full retraining of the model. Transfer Learning (TL) addresses this challenge by transferring knowledge learned in the source domain (the data it was trained on) to the target domain (a second set of data that is statistically different but related, which the model was not trained on). This study investigates the use of TL for street-scale nuisance flood forecasting by exploring whether an ML model trained for …

Enhancing Coastal Vulnerability Assessments And Policy Impacts On Socioeconomic And Environmental Equity In Michigan's Great Lakes Communities, Esther N. Acheampong

Dissertations, Master's Theses and Master's Reports

Accelerating shoreline erosion, fluctuating lake levels, and climate-induced hazards are transforming the Great Lakes’ freshwater coasts, exposing the limitations of static and inequitable management frameworks. This dissertation investigates how Michigan’s coastal governance systems produce and manage vulnerability along the Lake Michigan shoreline by integrating geospatial modeling, institutional policy analysis, and environmental justice theory. It argues that both physical processes and institutional designs co-determine patterns of exposure, protection, and equity. The research begins by developing a refined Coastal Vulnerability Index (CVI) tailored for lacustrine environments, applying it to Muskegon County to assess how shoreline change, armoring, and seasonality influence localized risk. …

Envisioning The Role Of Community-Owned Stores & Aligning Federal Food Policies: A Participatory Approach To Food Security And Food Sovereignty In Sambaa K’E, Denendeh (Northwest Territories, Canada), Narayan Subramoniam

Theses and Dissertations (Comprehensive)

Northern Indigenous communities have relied on traditional food systems for meaningful, nutritious diets since time immemorial. But many Indigenous communities in remote northern regions of Canada still face disproportionately elevated levels of food insecurity due to climate change radically altering the availability for traditional foods, colonial food policies imposing Western diets, and the high costs of transporting store-bought foods. Extreme weather events such as wildfires further isolate fly-in remote communities increasing both the costs of transporting store-bought foods and the difficulties of harvesting traditional foods. There are many examples of community-based initiatives for supporting traditional and locally grown foods, however, …

“Land Back With Strings Attached”: Centering California Indian Perspectives On The Integration Of Traditional Ecological Knowledge Into California Environmental Policy, Lauren Crane

Undergraduate Honors Theses

In response to a changing climate and while reckoning with their treatment of California Indians, the State of California has embraced Traditional Ecological Knowledge (T.E.K.) and is working to integrate it into their environmental policies. While many scientists and policymakers view T.E.K. as an important resource for environmental management, how do the holders of this knowledge perceive its integration? This research centers the perspectives of California Indian tribes who engaged with the state in the 2024 Tribal Nature-Based Solutions program - an example of a State policy to integrate T.E.K. Their perspectives highlight the different concerns, priorities, and preferred methods …

Book Review: Ecologies Of Inequity. How Disaster Response Reconstitutes Race And Class Inequality, Abel Traslaviña-Arias

Critical Disaster Studies

In Ecologies of Inequity: How Disaster Response Reconstitutes Race and Class Inequality, Sancha Doxilly Medwinter gathered diverse stories about how various migrant communities had to overcome not only disaster but also the overlapping networks established by those who were supposed to support them in 2012 in New York City. Medwinter portrays this contested post-disaster landscape through a thorough data recording of 120 individuals affiliated with various groups: racialized migrants or locals, tenants or property owners, local or external helpers, and those from wealthy or impoverished backgrounds. Ecologies of Inequity refer to the spatialized networks of organizational and interpersonal relations …

We will first analyze the role of social media in shaping public discourse on climate change and critically evaluate the priorities of institutions that have the means to assist in wildlife conservation. Both speak to the current behaviors of humankind prioritizing their own entertainment over meaningful efforts to mitigate climate change and preserve biodiversity. We will then shift to exploring the profound impact of human population growth and its associated activities on other species and ecosystems. Finally, the thesis will …

Evaluating The Preparedness Of Local Zoning Regulations For Flood Risk Reduction In The Most Affected Local Jurisdictions In Nebraska, Md Asaduzzaman Noor

Community and Regional Planning Program: Theses

Flooding has profound social, economic, and environmental impacts on local communities, and zoning plays a critical role in mitigating these risks. The 2019 Nebraska floods, among the most severe in the state’s history, highlighted the urgent need to strengthen local preparedness and mitigation strategies. This study assesses the extent to which local zoning regulations in Nebraska’s most affected jurisdiction, including rural areas, address flood risk reduction. A systematic review of 117 zoning ordinances from counties, cities, towns, and villages, we applied a structured analytical framework encompassing regulatory and permitting policies, voluntary and incentive-based measures, and nature-based solutions. The results show …

Safety, Security, And… Beavers? An Engineer's Low-Tech Climate Strategy, Matt Mullins

University College: Environmental Policy and Management Capstones

Colorado’s headwaters are the source of drinking water to millions and are a key pillar of the state’s tourism industry. Consequently, they are some of the most vulnerable areas to natural disasters including wildfires, droughts and flooding. Climate change will increase the severity and frequency of these natural disasters. This project focuses on some of the most vulnerable areas from an economic and climate change perspective of Colorado’s headwaters including the Big Thompson River, and the Colorado River. These headwaters located in and around Estes Park, Grand Lake and Rocky Mountain National Park are currently severely impaired. Low-tech process-based restoration …

Public Support For New Agricultural Best Management Practices To Protect Florida Water Quality, Sadie Hundemer, Madison A. Dyment, Matthew Gold

Journal of Extension

Recent research finds that changes to land management practices in geographically vulnerable areas of Florida could substantially reduce groundwater contamination; however, water quality improvement comes with tradeoffs. A change in land use or the adoption of new agricultural best management practices (BMPs) would have economic and cultural implications for farmers, rural communities, taxpayers, and the state as a whole. In two studies, we examined Florida residents’ support for alternative land management policy options, the considerations contributing to their policy preferences, and how preferences and considerations vary across demographic characteristics.

Optimizing Fleet Management: Evaluating The Feasibility Of Electric Vehicles And Leasing Strategies At The Utrgv Police Department, Van Edward Slusser

Doctoral Dissertations and Projects

The purpose of this applied dissertation was to improve readiness and cost discipline in a campus public-safety fleet and to assess the feasibility of electrification and leasing. A qualitative case-study design triangulated semi-structured interviews with stakeholders, administrative records (maintenance, fuel, costs), and telematics from eight vehicles to characterize duty cycles and constraints. Key findings were: stakeholders endorsed a phased, evidence-gated approach that relies on vehicle- and role-level analytics and coaching-based idle management; cost analysis supported availability-weighted replacement paired with warranty-anchored leasing to stabilize maintenance exposure and smooth appropriations; and telematics revealed role-differentiated patterns—administrative vehicles converted engine-on time to distance efficiently …

Wine-Rs Or Losers: Assessing The Socio- Economic Impact Of Eu Regulations On Climate-Exacerbated Pests And Diseases In Northern Italian Viticulture, Kyley Fishman

Claremont-UC Undergraduate Research Conference on the European Union

As climate change creates extreme weather events, unprecedented disease and pest infestations, European farmers are challenged by these threats. Balancing sustainable and traditional practices while maintaining socio-economic stability under European Union agroregulations can be extremely difficult. An area of concern for the EU is viticulture, which is among the most climate-sensitive agricultural sectors. My study examines in what ways the EU’s regulations addressing climate-exacerbated pests and plant diseases influence the socioeconomics of different vineyard farms in Northern Italy. Three key socio-economic findings emerged from the analysis. First, top-down and research-driven management strategies can subvert local, place-based knowledge, which undermines traditional …

Understanding Rice Production Stagnation In The Philippines: Regional Evidence And Development Implications, Henry Bartelet, Alenn Jhulia D. Prodigalidad, Janelle S. Dy, Jan Gabriel N. Manzano

Quantitative Methods and Information Technology Faculty Publications

Despite decades of investment in agricultural research and rice development, the Philippines continues to face stagnation in domestic rice production. This persistent trend, occurring despite a sizable arable land base and large rural workforce, has contributed to the country’s growing reliance on rice imports to meet national food needs. In response, the government has implemented a tariff-based import system designed to fund domestic productivity improvements. While previous studies have explored the technical and environmental constraints affecting rice production, such as irrigation shortfalls, land degradation, and climate variability, few have examined recent national trends using regionally disaggregated data alongside qualitative insights. …
