Measuring Agricultural Adaptation Using Remote Sensing: A Study Of Pigeonpea In Malawi, Maria Gorret Nabuwembo

Graduate Theses and Dissertations

Drought, heatwaves, and flooding cause tremendous damage to agricultural production in Malawi, and the continuous production of maize has led to widespread soil degradation. Additionally, climate change is transforming the environment at a scale beyond historical records, posing significant challenges to social, political, and economic systems. To combat these issues, agricultural innovations have been implemented, such as the installation of irrigation systems and development of heat/drought resilient crop varieties. Pigeonpea is one of the prominent drought-tolerant and temperature resilient crops grown as a diversification strategy since it allows farmers to adapt to changes while maintaining subsistence needs. This research investigates …

School Choice And Spatial Equity: A Comparative Analysis Of Public And Private K-12 School Enrollment In Three American Metropolitan Areas, John A. Schumacher

College of Arts & Sciences Senior Theses

This thesis investigates the factors influencing school choice and enrollment patterns in three Metropolitan Statistical Areas (MSAs): Detroit-Warren-Dearborn, MI; Louisville-Jefferson County, KY-IN; and Atlanta-Sandy Springs-Roswell. It explores the role of socioeconomic and spatial variables, including income levels, racial composition, and educational attainment, political fragmentation, and urbanicity in shaping enrollment decisions across public and private schools. Using spatial analysis and multiple regression techniques, the study examines how these factors contribute to variations in school enrollment within the selected MSAs. The results reveal that income level and racial composition significantly affect enrollment patterns while other factors such as urbanicity had minimal impact. …

Comparison Of Airborne Lidar-Derived Elevation Data In Fayetteville, Arkansas, Usa, Angelica M. Otting

Graduate Theses and Dissertations

Light detection and ranging (lidar) laser scanners are prominent remote sensing tools to produce high resolution three-dimensional (3D) imagery of the Earth’s surface. These laser scanners combined with global navigation satellite systems (GNSS) and real-time kinematic (RTK) reference stations can generate some of the most accurate ground surface imagery and elevation data for terrain mapping and related applications. Lidar aerial survey is an important tool in industries such as architecture, civil engineering, forestry, geology, geography, and agriculture where digital terrain models (DTMs) can be used to examine the geographical landscape and urban industry. Currently, there are three different common laser …

Assessing Spatial And Temporal Variation In Photoprotective Responses Of Deciduous And Evergreen Tree Canopies With Leaf Spectroscopy, Alexander Piper

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

Environmental conditions frequently prevent carbon fixation by plants, leading to the absorption of excess light that can damage photosynthetic machinery if not dissipated. To do so, plants utilize several photoprotective mechanisms, some detectable remotely using Photochemical Reflectance Index (PRI). Two components of PRI correspond to the facultative engagement of the xanthophyll cycle (ΔPRI) and constitutive changes in xanthophyll pigment pool sizes (PRI0), representing distinct mechanisms regulating shorter and longer-term photoprotection, respectively. Our understanding of interspecific and intraspecific variation in these mechanisms is limited, primarily because PRI components are often not clearly distinguished. This study aimed to assess the variation in …

Radar Precursors To Severe Weather Reports In Left-Moving Supercells, Eric A. Carothers

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

While much research has examined dual-polarimetric signatures of right-moving supercells, very little has been done with left-moving supercells. Given that left-moving supercells are thought to be disproportionate producers of large hail, understanding their internal dynamics is vitally important. This study examines differences and trends in the dual-polarimetric signatures of left-moving supercells to identify precursors to severe weather reports. A dataset of left-moving supercells associated with severe weather reports was created. These storms are processed with an automated analysis algorithm that identifies and quantifies the polarimetric signatures in each storm. A method for analysis of differences and trends in their dual-polarization …

Immigration Policy In The Second Trump Administration: Restriction, Removal, And The Limits Of Maga Nativism, Caroline R. Nagel

Faculty Publications

Donald Trump's three presidential campaigns have centred on promises to stop unauthorised immigration, whether by ‘building the wall’ or by enacting the largest mass deportation in American history. To deliver on these promises, Trump has appointed Stephen Miller—an anti-immigration hardliner who was responsible for the first Trump administration's draconian border policies – to a key White House position. Trump is often described as breaking from liberal-democratic norms; but when it comes to immigration policy, he is following a well-worn path by hiring Miller. This brief commentary places the Trump/Miller brand of anti-immigration politics in historical context, showing how anxieties over …

Advancing Snow Cover Observations In Glacierized And Alpine Environments Using Optical Remote Sensing, Rainey Aberle

Boise State University Theses and Dissertations

Warming air temperatures in recent years have led to declines in seasonal snow pack across western North America. These changes have profoundly impacted communities that depend on seasonal snow melt for water resources, as well as glaciers that act as critical long-term reservoirs in the region. While global snow cover extent products are available, they often fail to reliably distinguish between snow, glacier ice, and clouds, which are prevalent in western North America. Additionally, water managers in the region typically rely on point-based observations of snow mass for decision-making, despite the pressing need for comprehensive, watershed-scale estimates. To address these …

Contesting The City Through Sustainability Discourse: A Joint Archival And Interview Analysis Of City Planning In Louisville, Kentucky., Calvin Grant

Electronic Theses and Dissertations

Sustainability is a part of a global discourse cast as a universal, technocratic solution to the climate crisis in need of a receptive public and active local adaptation. In many cases, language espousing sustainable development ideals and policy implementation promotes a perspective of scientific neutrality that overlooks socio-politically grounded discourses. This joint archival and interview-centered discourse analysis demonstrates that official sustainability discourse in Louisville’s Comprehensive Plan 2040 was produced through a carefully moderated consensus among planners and select stakeholders. Such consensus prioritizes the perspectives and agency of policy experts, business leaders, and others who have “recognized speech” of authority, while …

Belly Dance In Nebraska: Identity, Social Acceptance, And Perseverance, Alex R. Mohr

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Belly dance is an art form as well as an often-contested practice due to tensions over dress, terminology and cultural practices within the belly dance community because the dance originated outside the United States. Additionally, there is often a need to prove the legitimacy of the dance to those outside its sphere because it is often stigmatized due to the early association with exotic dancing. Belly dance is inherently geographic, as seen through its places of origin, music and movement styles, global spread, practitioners, and spaces of practice. However, it has not been well-represented in geography, and there is also …

Mapping The Underthing: Literary Geography And Geographic Education In The Slow Regard Of Silent Things, Colby Mcclain

Master's Theses

This thesis examines the imagined geography of Patrick Rothfuss’ The Slow Regard of Silent Things. Through textual analysis, it investigates how fictional spaces can be mapped, the significance of toponyms (i.e., place-names), and the broader implications for literary and geographic studies. Of the fifty-two (52) toponyms analyzed, thirty-eight (38) were meaningfully identified using the text and the Oxford English Dictionary (OED), revealing deliberate naming schemes associated with function, emotion, or symbolism. These findings provide insight into the main character’s world, and her unique relationship with space and place. This study demonstrates that even wholly imagined settings have an underlying …

Changing Climate, Changing Minds: Social Media's Role In Shifting Climate Change Beliefs, Rachel M. Clarke

All Graduate Theses and Dissertations, Fall 2023 to Present

This study explores how social media messages influence individual beliefs, attitudes and behaviors related to climate change. Despite widespread exposure to social media, there is concern about its effectiveness in shaping beliefs and actions regarding climate adaptation and mitigation. Research indicates that many people in the United States show limited concern for climate change, underscoring the need for targeted communication strategies. By designing and implementing a survey experiment with random participants within the United States, this study examines how sharing first- person experiences of climate-related hazards on social media affects opinions about climate change, in comparison to traditional third-person news …

Geospatial Modeling Of Winter-Related Property Damage In Arkansas, Braedyn Mcbroom

Graduate Theses and Dissertations

Storm Data, a monthly publication by the National Weather Service with records of weather events, reports on property damage caused by natural hazards. Since 1996, the database has included winter-related events. While the property damage data is considered incomplete, no other unique, public datasets report winter-related property damage at the county level. From 1996 to 2024, Arkansas ranked #1 in winter-related property damage. To understand the factors that are driving property damage and potentially reduce Arkansas’ vulnerability to it, three groups separated by temporal periods, i.e., “2000” (01/1996 - 06/2005), “2010” (07/2005 - 06/2015), and “2020” (07/2015 - 06/2024) …

Improving Nutrition Outcomes Through Enhanced Allocative Efficiency Of Investments In 24 High Risk Counties In Kenya: An Optima Nutrition Modelling Study, Morris Ogero, Nick Scott, Veronica Kirogo, Anthony Ngugi

Population Health, East Africa

Introduction ;Undernutrition remains a significant global challenge, severely impacting children’s development and growth. To address this, the Sustainable Development Goals target a substantial reduction in stunting and wasting by 2025. Achieving these goals requires scaling up evidence-based nutritional interventions; however, limited budgets pose challenges in funding all necessary programs. To assist policymakers in making informed decisions, the World Bank developed the Optima Nutrition Modelling tool, which optimizes the allocation of nutrition investments. Kenya, with its high prevalence of stunting, was the focus of this study. Using the Optima Nutrition model, we aimed to (1) assess the impact of scaling up …

Considerations And Techniques For Producing Urban Tree Canopy Maps Using Freely Available And Accessible Methods, Hugh Reed Ellerman

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Urban forests are valued as green infrastructure for the variety of benefits they provide across ecological, social, public health, and economic domains. To understand the distribution of trees, maps are required. Many methods of mapping tree cover use expensive and data-intensive datasets such as hyperspectral and LiDAR imagery, making these methods inaccessible to municipal forest managers. Variations in the modelling approaches of existing, freely available methods are not addressed in sufficient enough detail to understand the trade-offs implicit in these variations. Further, characteristics of urban tree canopy mapping (high spatial resolution imagery, heterogeneous urban environments, the importance of the tree …

Entangled Exclusions: Borders, Frontiers And Urban Geopolitics From Northeast India, Prerona Das, Gaurav Mittal, Jasnea Sarma

Research Collection College of Integrative Studies

An epicentre of ethnicity-based identity politics and exclusions, India's northeastern region has long been politically imagined as both a ‘frontier’ and ‘borderland’ for state control, territorialization, extractive economies and (re)developments by colonial and subsequent post-colonial regimes. In post-independence India, the region experienced many territorial assertions made on ethnic grounds. With the rise of religio-national and neoliberal politics, new urban ‘developments’ and connectivity projects in the region have deepened exclusions based on class, caste, ethnic and religious borders. These have, in turn, led to further displacement, enclavization, and ghettoization of minority communities who are deemed ‘non-native’ along ethnocentric lines. Taking two …

Infrastructuring Planetary Rural Geographies: A View From China’S Rural Construction Movement, Ningning Chen, Lily Kong, Yurui Li

Research Collection School of Social Sciences

This commentary responds to Wang et al.'s (2023) call for planetary rural geographies by attending to the neglected infrastructural dimensions. In so doing, we show how China's rural construction movement demonstrates Wang et al.'s (2023) three geographies of planetary rurality: as spaces of crisis, conflict, and hope. Simultaneously, we address how planetary rural thinking can foreground infrastructural geographies and their destabilization of urban-centered discourses, leading to a reconsideration of rural–urban relationality. We then identify new insights that critical infrastructural studies offer to planetary rural geographies. This includes an emphasis on the material grounds, hidden politics, and non-linear temporal patterns of …

Mapping Homes Of Georgia's Governors And Their Westward Shift (1776–2024), Andrew J. Bramlett

Symposium of Student Scholars

Since the start of the American Revolution, seventy-seven men have served as Governor of Georgia. Over time, the state expanded westward from the coast to become the largest state east of the Mississippi River. Although individual governors have been studied extensively (particularly in James F. Cook’s The Governors of Georgia), their residences remain underexplored as indicators of electoral power shifts. Based on the information of seventy-seven governors collected from Cook, the New Georgia Encyclopedia, and Georgia Historical Quarterly, this research visualizes the residences of governors at the time of their election by using ArcGIS and reveals the state’s electoral …

Territorio Anfibio Y Agroalimentario. La Ruralidad Cenagosa, Cristan Abad Restrepo

Educación

Las comunidades que habitan los ecosistemas cenagosos gestionan su vida en conjunto con el agua. Existe un espacio relacional donde todo es interacción, de allí que el bienestar de las poblaciones depende de la calidad del agua de las ciénagas, de la producción del pescado y de la biodiversidad. Sin estas condiciones, los territorios anfibios no pueden reproducir la vida. Cuando el río, el caño y la ciénaga no realiza el intercambio hídrico, las comunidades entran en crisis, porque materialmente depende de esta para sobrevivir. Gestionar esta relación es fundamental para garantizar la vida local. Esta cartografía social del corregimiento …
