Growing Agroecology: Two Case Studies From The U.S. Student Farm Movement, Amelia B. Armstrong

Graduate Student Theses, Dissertations, & Professional Papers

Scholars and activists identify agroecology as a crucial science, practice, and movement to move towards more just, equitable, and sustainable agriculture and food systems. Yet, the exploitative industrial food system, that deepens inequalities like food insecurity (Clapp et al., 2025), reduces farmer autonomy (Rotz, 2015), and contributes to increased carbon emissions (Lin et al., 2011) and biodiversity decline (Rotz, 2015), still dominates. Understanding and mobilizing the different spaces that teach agroecology, then, is a crucial step in challenging the dominant industrial food system. Agroecology education in university settings is an important domain to investigate as potential contributors to this movement, …

Heart Of Stone: Geomorphization Through Stone-Oriented Affects, Grace F. Foster

Graduate Student Theses, Dissertations, & Professional Papers

This thesis draws from the work of geologist Marcia Bjornerud to bring a scientific (specifically geologic) understanding of humanity’s relationship to our home planet to bear in a literary context. I employ Bjornerud’s term “geomorphization” to expand from inter-species kinship to inter-substance kinship and to establish stone as an active, lively subject without relying on anthropomorphization. Geomorphization as I define it refers to recognizing similarity between ourselves and stone/Earth on the basis of our stoniness rather than stone’s human-ness. Geomorphizing ourselves entails what Bjornerud calls “timefulness,” a geologic perspective on temporality that sees the past as continually acting in the …

Machine Learning For Predictive Energy And Emissions Modeling Of Vehicles And Power Grids In The United States, S M Tanvir Faysal Alam Chowdhoury

Dissertations

The environmental benefits of electric vehicle (EV) adoption depend on more than replacing internal combustion engine vehicles with electric powertrains. EV adoption reshapes electricity demand, interacts with regional generation mixes, and influences travel behavior and congestion, creating a coupled transportation-energy system in which vehicle and power-plant emissions must be evaluated together. This dissertation develops machine-learning frameworks for predicting energy consumption and emissions from vehicles and power grids under rising EV adoption. The first component forecasts grid emissions from EV charging. Using simulation data from NREL's Cambium database, a Prophet-based time-series framework predicts carbon dioxide, nitrous oxide, and methane emission rates …

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, …

At A Crossroads: Crisis, Vulnerability, And The Possibility Of Transformation Of Nature-Based Tourism In Canada, Brooklyn Rushton

Theses and Dissertations (Comprehensive)

We live in an era shaped by a global polycrisis, where climate change, pandemics, economic shocks, geopolitical tensions, and social inequities are converging to create complex, cascading, and compounding risks. For Canada’s nature-based tourism sector, situated at the nexus of social and ecological systems, the polycrisis both amplifies the vulnerabilities of tourism and highlights tourism’s role in perpetuating global risks. Recognizing this duality, this dissertation examines how crises amplify systemic vulnerabilities while also acting as leverage points for transformative change in Canada’s nature-based tourism sector, drawing on geography, systems thinking, resilience theory, regenerative tourism, and futures thinking scholarship.

What Are The Global Differences In Air Quality Due To The Covid-19 Pandemic?, Jude Spencer, Ian Mcgee, Brandon Solis-Martinez

Student Scholar Symposium

The COVID-19 pandemic led to unprecedented global disruptions, including significant changes in air quality due to lockdown measures, reduced industrial activity, and shifts in transportation patterns. Air pollution, primarily from nitrogen oxides (NOₓ), carbon dioxide (CO₂), and particulate matter (PM2.5), is a major environmental and public health concern. While some studies suggest temporary improvements in air quality during lockdowns, long-term impacts remain uncertain across different regions. To examine this, we investigated the research question: "What are the global differences in air quality due to the Covid-19 pandemic?" Using peer-reviewed studies from the Greenfile and ScienceDirect databases, along with EPA data, …

How Does Vertical Hydroponic Farming Compare To Traditional Soil Farming In Terms Of Crop Yield, Energy Efficiency, And Cost?, Grace Morgan, Grace Henry, Rebecca Meenach, Jeana Odom

Student Scholar Symposium

Vertical hydroponics (hydro “water;” ponics “labor”) is a method of year-round farming that uses water in place of soil and supplies vegetables’ nutrients in a space-efficient setting. It dates back to 500 BC when it was used in the Hanging Gardens of Babylon, a wonder of the ancient world. Thousands of years later, vertical hydroponics has expanded across the globe to supply leafy greens, herbs, and grains. It is typically implemented in dense urban environments where green space is hard to come by as a form of sustainable farming. Our research seeks to answer the question “How does vertical hydroponic …

Kalunga Crossings: Waterscapes Of Terror And "Teachment" In The African Atlantic World, Dianne M. Stewart, Tracey E. Hucks, Solimar Otero

Yale Journal of Music & Religion

In this article, we think alongside historian of religions Charles H. Long to analyze the relationship between water and empire, explore theoretical approaches to water and modernity, and probe the significance of water in Africana ecologies and spiritual cultures, highlighting its suggestive contributions to restorative epistemologies of ecological co-habitation. Our investigation advances an Africana religious framework of “waterscapes of terror and ‘teachment’” that centers diaspora bodies of water as loci for analyzing history, materiality, and ecological regard. Teachment is an anti-colonial linguistic irruption, an all-encompassing term for Africana pedagogies and epistemologies that defy antiblack and anti-African colonial instruction. Examining how …
