Spatial Analysis Of Heavy Metal Leaching Threats From North Dakota Landfills To Drinking Water Aquifers, Leila Campbell May 2026

Spatial Analysis Of Heavy Metal Leaching Threats From North Dakota Landfills To Drinking Water Aquifers, Leila Campbell

Arts & Sciences Undergraduate Showcase

Groundwater is a primary fresh water source for most rural communities in North Dakota. The EPA acknowledges that landfill leakage is not a matter of if but when, and early detection can be extremely difficult. This project identifies which counties and aquifers face the greatest threat from landfill heavy-metal leaching based on proximity, waste types, and groundwater vulnerability, thereby indicating which landfills warrant the closest monitoring and regulatory compliance.   The methodology combines two indexes. The DRASTIC index identifies aquifer vulnerability to surface pollution based on hydrogeologic factors. These factors are weighted by their significance to produce a score that reflects …

The Queer Family Farm: Exploring Agrifood Justice And Management Philosophies Among Lgbtq+ And Family Farmers In Minnesota And Wisconsin, Julia I. Castellano

Geography Honors Projects

Agriculture in the US countryside has long been idolized as a symbol of traditional American values via the “family farm” while queerness has become associated with avant-gardism and urbanity. This study contributes to the nascent but growing scholarship at the convergence of these seemingly opposing propositions: queer farming. Specifically, I contextualize LGBTQ+ farmers in Minnesota and Wisconsin through historical and modern perspectives on the dominant heteronuclear family farm and industrial agricultural landscape to understand how they approach farming in the absence of traditional gender roles and as predominantly small, alternative farmers. The family farm as we imagine it today is …

Food Sovereignty In Post-Apartheid South Africa: A Case Study Among Gardeners And Non-Gardeners In Genadendal, Western Cape, Timothy P. Delventhal

Geography Honors Projects

In post-Apartheid South Africa, large-scale commercial farming is promoted by the state as the only viable agricultural development model, while small-scale agriculture is marginalized in development discourse and the national land reform program aimed at addressing historical wrongs. However, food sovereignty movements across the Global South, such as Via Campesina, have promoted small-scale gardening for communities to gain control over their food systems and prevent the distancing of food from the labor that produced it. The research question investigated is whether people in the Genadendal area who grow their own food from gardens have better dietary diversity outcomes and increased …

Creating A Gis-Based Site Suitability Index For A Major Sports Stadium In Kansas City, Theodore E. Blair May 2026

Creating A Gis-Based Site Suitability Index For A Major Sports Stadium In Kansas City, Theodore E. Blair

Political Science Undergraduate Honors Theses

There are many considerations taken when siting major sports stadiums. Most literature, though, has focused on the political and economic considerations, the negative outcomes of using public money for private projects. However, geographic considerations play a major part in deciding where to site a stadium. These considerations are wide-ranging and can change with the times. This thesis determines ten modern site suitability criteria, and with them, creates a site suitability index using GIS to determine and quantify more and less suitable areas for stadium development. It applies this index to the Kansas City area, as the city is currently in …

Modeling Bicycle Ridership In Northwest Arkansas, Nelofar Qulizada May 2026

Modeling Bicycle Ridership In Northwest Arkansas, Nelofar Qulizada

Graduate Theses and Dissertations

In a global comparison, the U.S. ranks second lowest in bicycle use for urban trips, surpassed only by Brazil. This underutilization signals missed opportunities to improve public health, environmental sustainability, and community connections. In Northwest Arkansas (NWA), a region actively investing in active transportation infrastructure, efforts were underway to reverse this trend. However, a key question remained: Were these investments effectively boosting bicycle ridership? To address this question, communities required reliable methods to measure cycling activity. Traditionally, this involved stationary counters placed at strategic locations to monitor ridership patterns. While accurate, these counters had limited spatial coverage. In contrast, emerging …

The Effects Of Impervious Land Cover And Red Tide (Karenia Brevis) On The Florida Manatee (Trichechus Manatus Latirostris) In The Gulf Coast Of Florida, Anna Compton May 2026

The Effects Of Impervious Land Cover And Red Tide (Karenia Brevis) On The Florida Manatee (Trichechus Manatus Latirostris) In The Gulf Coast Of Florida, Anna Compton

Honors College Theses

Red tide, caused by the dinoflagellate Karenia brevis, is an algal bloom event that occurs annually in the West Florida Continental Shelf. The algae releases brevetoxin, a toxin that can be fatal to wildlife in high concentrations. These algal bloom events are thought to be exacerbated by warming ocean temperatures and increased nutrient runoff from urbanization. Red tide is responsible for the mass mortality of various marine organisms like the Florida manatee (Trichechus manatus latirostris). This study analyzes the changes in nutrient runoff and sea surface temperatures, and how these factors affected red tide cell concentrations and Florida manatee mortalities …

The Personality Of Place: Physical Geography And The Shaping Of The Nineteenth-Century German Immigrant Ethnic Identity, Abigail Ward May 2026

The Personality Of Place: Physical Geography And The Shaping Of The Nineteenth-Century German Immigrant Ethnic Identity, Abigail Ward

Honors Theses

In the nineteenth century alone, approximately five million German-speaking immigrants arrived in America. However, the motivations of these individuals for moving to America, far from identical, were nearly as numerous as the individuals themselves. The German ethnic identity in America was not uniform, but the expression of many factors having to do with both the Vaterland and the new land. These factors ranged from the timing of emigration, which was largely influence by religious, political, and economic upheaval in Europe, to each German’s system of values, which dictated the kind of future he saw for himself and therefore where he …

From Guyana To Queens: The Formation Of The Indo-Guyanese Ethnoburb In New York City, 1970-1990, Lianne R. Persaud

Theses and Dissertations

Expanding on Li’s concept of ethnoburbs, this study examines Indo-Guyanese settlement in Little Guyana, Queens (1970–1990). I propose the Vertical Enclave Model, which suggests that multi-family homeownership and internal rental markets facilitated the residential permanence of working-class individuals. The IPUMS Census microdata corroborates this community’s reliance on metropolitan integration, thereby refuting traditional self-sufficient ethnic enclave theories.

Conventional Vs. Regenerative Apple Orchard Management In Michigan, Anthony Poynter May 2026

Conventional Vs. Regenerative Apple Orchard Management In Michigan, Anthony Poynter

Masters Theses

This study compares the variables and outcomes of a conventional apple orchard and a regenerative apple orchard production system in Kent County, Michigan. The premise is that conventional agriculture relies on high-input systems characterized by synthetic fertilizers, pesticides, herbicides, and fungicides, while regenerative agriculture focuses on long-term soil health, biodiversity, and ecological processes. These differences are important as soil degradation, nutrient loss, and environmental impacts are becoming too significant to ignore. Most research on alternative ways to farm, such as regenerative practices, is focused on annual crops, while perennial orchard systems, especially in the Great Lakes region, have gained limited …

Passive Microwave Remote Sensing Of Flash Drought Impacts On Vegetation, Quinton R. Deppert May 2026

Passive Microwave Remote Sensing Of Flash Drought Impacts On Vegetation, Quinton R. Deppert

School of Natural Resources: Dissertations, Theses, and Student Research

In 2002, Dr. Mark Svoboda characterized a new form of drought known as flash drought. Flash drought was defined as a rapid decline in vegetation health caused by severe heat and drought. In recent years, attempts to quantify the impacts of flash drought via precipitation, soil moisture, evapotranspiration, and temperature indicators have proliferated. What has rarely been quantified is what the rapid decline in vegetation health amid flash drought looks like through remote sensing. This is because vegetation health indices like the Normalized Difference Vegetation Index (NDVI) are derived from the visible and infrared regions of the electromagnetic spectrum and …
