Chronic Inequities: Environmental & Structural Racism During Covid-19 And Hurricane Laura Disaster Recovery, Tomeka M. Robinson, Sabrina Singh

Critical Disaster Studies

The COVID-19 pandemic has amplified the realities of systemic health inequities within the United States. While the virus has severely impacted the entire country, people of color bear the brunt of this pandemic, from surges of COVID-19 cases in their communities to spikes in unemployment rates. Simultaneously, citizens are dealing with the impacts of natural disasters such as hurricanes along the Gulf Coast. The common denominator concerning these two stressors is that they can be exacerbated by institutional racism. This can be seen in the case of a small city in Southwest Louisiana, namely, Lake Charles, which has become a …

Book Review: The Shaming State: How The U.S. Treats Citizens In Need, Steve Matthewman

Critical Disaster Studies

Salman’s book centers two different constituencies, in two different locations, in the 2010s, who have been impacted by two different disasters. The first group are Iraqi refugees who have been resettled in Wayne County, Michigan. Trying to start again over half a world away, they are trapped in the transit lounge of life, never able to move on, never able to properly belong. They found a state in recession, the automobile industry collapsing, the city of Detroit bankrupt. Their particular county had higher unemployment than the state’s average and a poor median income as well. Economically speaking, ‘Michigan fared worse …

Caring For Creation: Catholics, Justice, And Socio-Ecologies In Appalachia, Dominic Wilkins

Dissertations - ALL

Geographers have long studied the challenge of achieving holistic justice. Rather than something found wholly within human relations, in recent years these analyses have increasingly understood justice as socio-ecological. The Catholic Church is a global institution with more than 1.3 billion adherents and millions of employees operating hundreds of thousands of parishes, schools, and other institutions across the world. The Church has long centered justice through both activism and intellectual theorizing. To date, however, geographers have not rigorously engaged this work or the ongoing environmental turn within the Catholic Church and its conceptions of justice. Scholars specializing in religions and …

No. 19: Covid-19, Food Insecurity And South Sudanese Urban Refugees In Nairobi And Nakuru, Kenya, Cherie Enns, Samuel Owuor, Abbey Lin, Natasha Knebelow, Jacqueline Fanta, Cobby Achieng, William Kolong, Kristin Swardh

Migration and Food Security (MiFOOD) Network

The challenges and struggles of refugees are well documented, mainly within refugee camps. However, more needs to be documented and understood about the exertions and hardships of urban refugees, including the experiences of young South Sudanese urban refugees living in Kenya. Although Kenya is one of the major countries that hosts refugees from South Sudan, it has adopted disparate policies for refugees in camp settings and those outside the camps. This divergent approach placed urban South Sudanese refugee youth in highly precarious circumstances during the COVID-19 pandemic. Rampant food insecurity for refugee youth was one of the key negative consequences. …

A semi-structured interview was then conducted with a local environmental justice activist to gain a better understanding of their experience and the barriers to environmental justice for the residents of West Louisville. This study improves our understanding of community needs and adds a …

What's In A Name? Plant Naming As Cultural Artifact And Story In The Midwestern United States, Sophie Wesseler

Undergraduate Theses

This project sought to collect and contextualize the historical and contemporary names given to plants by inhabitants of the Midwestern United States, understanding plant names as cultural artifacts that can offer insight into the communities in which they were created and evolved. Formatted as a series of entries, this collection gathered these names and contextualized them within other artifacts of cultural significance, such as art or poetry, and alongside historical research on their origins and cultural environments. Examining plant names through the fields of linguistics, semiology, anthropology, cultural studies, taxonomy, and ethnobotany, this work traces the names of various plants …

A Sensor-Based Simulation Method For Spatiotemporal Event Detection, Yuqin Jiang, Andrey A. Popov, Zhenlong Li, Michael E. Hodgson, Binghu Huang

Faculty Publications

Human movements in urban areas are essential to understand human–environment interactions. However, activities and associated movements are full of uncertainties due to the complexity of a city. In this paper, we propose a novel sensor-based approach for spatiotemporal event detection based on the Discrete Empirical Interpolation Method. Specifically, we first identify the key locations, defined as “sensors”, which have the strongest correlation with the whole dataset. We then simulate a regular uneventful scenario with the observation data points from those key locations. By comparing the simulated and observation scenarios, events are extracted both spatially and temporally. We apply this method …

Bay Water Level Influences On Inundation And Morphological Changes Of A Semi-Connected Barrier Island During A Hurricane, Sydney D. Goodman

Graduate Theses and Dissertations (2019 - present)

This research aims to identify flooding and erosion changes along a semi-connected barrier island system due to varying bay water levels during storm conditions. The numerical model XBeach is used to simulate Hurricane Michael conditions and the resulting inundation and morphological change near Tyndall Air Force Base (Tyndall AFB). The installation is located 12 miles southeast of Panama City Beach along the panhandle of Florida and is vulnerable to flooding due to its proximity to the Gulf of Mexico (GoM), Saint Andrew Sound and Saint Andrew Bay. A land bridge connects the barrier island to the mainland of Tyndall AFB …

Assessing Urban Tree Coverage Along The U.S.-Mexico Border: A Gis Analysis Of Paso Del Norte, Melanie Escobar

Open Access Theses & Dissertations

In recent years, researchers have extensively studied the spatial distribution of social demographics and urban tree canopy (UTC) in urban cities, but very few, to this date, address U.S.-Mexico border cities. To date, there is no research that assesses the distribution of urban tree canopy (UTC) in the city of El Paso, Texas, and Ciudad Juarez, Chihuahua, along the U.S.- Mexico border. Leveraging advanced mapping techniques and GIS tools, the study performs comparisons between countries (Juárez vs. El Paso urbanized areas and intra-country (within each country). It compares land cover classifications, assesses variations in UTC distribution across census tracts and …

Water Equity And Planning: Acid Mine Drainage In Deckers Creek Watershed, Brooke O. Waters, Lennon Jewell Auvil, Grace Dever

Undergraduate Scholarship

When mines close, they simply do not disappear. They cannot be buried or forgotten about. The implications of mining leave a lasting history and impact not only on our lands but on the people as well. Abandoned mine lands are areas of our community and environment that have been destroyed due to the extraction of coal and other minerals. Mining results in the destruction of landscapes, contamination of waterways, and the emission of harmful chemicals to our communities.
Acid Mine Drainage (AMD) is a resultant water pollutant that is derived from mining practices, active or abandoned. This pollutant forms from …

Community Conservation In Madagascar: Aligning Local Livelihoods And Biodiversity Protection, Jane Slentz-Kesler

Geography Honors Projects

The management of natural resources in developing countries is of utmost importance as both high levels of biodiversity and local livelihoods often hang in the balance. The debate in conservation spheres often centers on 'fortress' versus 'community-based' conservation approaches, one emphasizing nature preservation and the other emphasizing the needs and empowerment of local communities in resource management. This study evaluates the management approach of a rainforest in northeast Madagascar, asking: how effectively does the COMATSA Sud protected area management system both preserve critical forest cover and provide for the local community? This research employs a mixed-methods approach, using interviews and …

Net Fluxes Of Broadband Shortwave And Photosynthetically Active Radiation Complement Ndvi And Near Infrared Reflectance Of Vegetation To Explain Gross Photosynthesis Variability Across Ecosystems And Climate, Kanishka Mallick, Joseph Verfaillie, Tianxin Wang, Ariane Arias Ortiz, Daphne Szutu, Koong Yi, Yanghui Kang, Robert Shortt, Tian Hu, Mauro Sulis, Zoltan Szantoi, Gilles Boulet, Joshua B. Fisher, Dennis Baldocchi

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

A significant challenge in global change research is understanding how vegetation interacts with the environment to influence ecosystem gross primary productivity (GPP) through carbon assimilation. One emerging objective is to consistently predict GPP fluctuations worldwide by establishing a robust scaling relationship between GPP measured at flux towers and satellite spectral reflectance data. However, a major hurdle in achieving this goal is the discrepancy in spatial resolution between early satellite measurements and eddy flux measurements. By using a large set of growing season data covering 100 site-years in North and Central America, we explored the potential of transforming incident and reflected …

It is primarily a map of units in the area, but also contains other important geographic data such as schools, school districts, and chartered partners in Central Minnesota. The map was built in ArcGIS Pro in cooperation with Gerry Granum of the BSA.

Mapping Racial Covenants In Stearns County, Mn, Jonathan D. Carlson

Celebrating Scholarship and Creativity Day (2018-)

Over the past year, CSB and SJU Honors students uncovered previously unknown racial covenants included in property deeds in Stearns county. Racial covenants prevent people of certain races from owning or occupying property, thus creating segregated neighborhoods. The Great River Covenants Project (https://greatrivercovenants.org/) was created to educate the public about this work. Using Geographic Information Systems, I created maps to show the location of the covenants and when they appeared in neighborhoods through the decades of 1920 to 1960.

Family Medicine’S Role In Addressing The Intersections Of Redlining And Climate Change, Daryl O. Traylor, Eboni E. Anderson, Brianna Clark, Alex M. Smith, Cooper K. Allenbrand

Journal of Sustainable Social Impact

Redlining, the practice of discriminating against specific neighborhoods based on race and socioeconomic status, leads to persistent environmental hazards and socioeconomic inequalities that have lasting adverse health effects on their populations. Health disparities are further exacerbated through the concentration of environmental hazards, as well as the escalating impact of climate change, which poses an increased risk of respiratory illness, cardiovascular disease, mental health issues, heat-related illness, infectious diseases, food insecurity, and socioeconomic difficulties in redline neighborhoods.

This paper examines the interplay of redlining, climate change, and health disparities, with an emphasis on the enduring consequences for these marginalized communities. Through …

Human-Environment Interactions In Coastal Belize: Insights Into Sea-Level Rise And Ancient Maya Activities At The Paynes Creek Salt Works, Cheryl Mae Foster

LSU Doctoral Dissertations

Dissertation excavations were carried out in 2019 and 2022 at the underwater sites of Ta’ab Nuk Na and Ek Way Nal in Paynes Creek National Park, Belize. Sea-level rise submerged the sites in antiquity and preserved the artifact record in red mangrove (Rhizophora mangle) peat. Red mangrove peat can be used as a proxy for sea-level rise. The goals of the two excavations included: 1) excavating a 14m-long transect within and extending beyond building J at Ta’ab Nuk Na to determine the function of the building, 2) investigating the production of salt making pottery at Ta’ab Nuk Na; …

Positioning Disability In Wilderness Space, Rebecca Hobart

Geography ETDs

This thesis examines the social construction of the disabled body in recreational wilderness space. A political ecology framework guides the research questions: What are the actual or perceived barriers to participation for differently abled hikers in wilderness recreational spaces, and how do these challenges manifest in long-distance hiking spaces? In situating Foucault’s theories of the body as shaped by power relations, this thesis asserts wilderness spaces to be privileged based on power conceptualized in normative notions of ability. 44 participants who self-identified as wilderness recreationalists with a disability and/or chronic health illness completed this study’s mixed-method questionnaire. Themes around practices, …

Effects Of Social Media Use Disparities On Community Resilience To Disasters, Kejin Wang

LSU Doctoral Dissertations

With the rapid development of social media, many researchers chose to use social media data to conduct studies of disaster resilience. This dissertation addresses three fundamental challenges related to social media use and disaster resilience analysis including: how the spatial analysis scale affects the results of social media use disparity and its impacts on disaster resilience; how different vulnerability and resilience measurement methods can generate very different results; and how social media use disparity can be identified to help improve the fairness of AI-based emergency rescue model development. Therefore, the first part of the dissertation measured the relationships between disparities …

Design And Test The Effectiveness Of Interpretive Signs Using Eye Tracking And Biometric Data, Hadara Gordon, Wendy Miyazaki

Baker/Koob Endowments Awarded Projects

Recreational trails on forested lands should satisfy the needs of recreationists, safeguard important habitats, and maintain the natural environment (Kortenkamp et al., 2021). Appropriate management is critical because of the increasing number of visitors. Signs are a cost-effective method to reduce the negative impacts on visitors and enhance visitor experiences (Brown et al., 2010). This research aimed to investigate how visitors pay attention to signs, view the trail surrounded by trees and behave in a natural space.

Gis-Based Multi-Criteria Decision Analysis For Marine Energy Site Selection: A Case Study Comparison Between Puerto Rico And Hawaii, Sarah Hall

Environmental Studies Honors Papers

Geospatial information systems (GIS) enable easy visualization of geospatial data representing different criteria important for optimal siting of marine energy projects. Multi-Criteria Decision Analysis (MCDA) is a geospatial analysis method that facilitates the evaluation of multiple, usually overlapping, site criteria. While GIS-based MCDA has been used extensively for land-based renewable energy projects, limited research exists on its application to marine-based renewable energy projects. Similarly, most literature overlooks the integration of social or environmental justice data. This project applies GIS-based MCDA to conduct site selection analysis for two marine renewable energy (MRE) projects in Puerto Rico and Hawaii. The results for …

A Study Of Multimodal Accessibility Equity And Spatio-Temporal Relationships Between Transit, Job Density And Modal Split, Seyedsoheil Sharifiasl

Planning Dissertations - Archive

In North American cities, the land use and transportation systems are associated with low-density, suburban-type urban development, where the built environment contributes to a mobility pattern that is extremely reliant on automobiles. Several studies in the past decades have documented noticeable and concerning patterns of unjust and unsustainable transportation in this context. As a result, for those population groups with limited access to private transportation, this form of urban structure is equivalent to limited access to opportunities, leading to various environmental and social problems. These problems exacerbate inequities in access to transportation, disproportionately affecting marginalized communities. From a sustainable development …

Across the Northwest Territories (NWT), Canada, Indigenous populations are striving to achieve effective environmental protection, whilst navigating complex methods, policies, and research relationships within co-management contexts. This thesis seeks to identify how differing cultural systems, environmental change, and fractured partnerships may be unified to align with the needs of the Sambaa K’e First Nation (SKFN), a remote Dehcho Dene community. Indigenous methodologies guided co-development of research questions with SKFN leadership which yielded objectives a) develop a GIS-based method to manage, organize and mobilize cultural and environmental data; b) develop a new stewardship monitoring procedure so that users can apply the …

Beauty And The Anthropocene: On The Emancipatory Potential Of Experiences Of Beautiful Places In The Natural World, Matthew John

Theses and Dissertations--Geography

This dissertation investigates the proposition that beauty—specifically, experiences of beautiful places in the natural world—can contribute to the emancipation of modern persons (and thereby developed societies) from instrumental rationality, which is theorized as a major driver of contemporary socioecological crises of the Anthropocene. Buber’s concept of the I–Thou relation provides a framework for conceptualizing ideal non-instrumental relations. The project’s methodology, rooted in post-phenomenology, consisted of semi-structured remote interviews and four follow-up focus groups with 35 then current and recently former residents of Juneau, Alaska. Taken together, data confirm that experiences of beautiful places in the natural world can and do …

Thirty Years Of ‘Emergency’ Food Aid In The Us And Canada: Findings From Comparative Research To Inform Uk Efforts To Tackle Food Poverty And The Need For Foodbanks, Charlotte Spring

Geography and Environmental Studies Faculty Publications

Research observed how food providers in the United States and Canada have made changes during the decades of neoliberal policymaking that have seen foodbanking expand across North America and beyond. These changes, in part, reflect responses to critiques of foodbanking as an inadequate solution to food insecurity. Food charities have variously attempted to improve provision through healthier procurement, choice-based distribution models, diversified programming, and advocacy for policy solutions. Better foodbanking, however, does not negate the influence of corporate donors on food charities’ capacity to foster hunger-preventative change, such as the employment practices of those same donors. Meanwhile, grassroots organisers …

Climate Change And Critical Agrarian Studies, Ian Scoones, Saturnino M. Borras Jr., Amita Baviskar, Marc Edelman, Nancy Peluso, Wendy Wolford

Publications and Research

Climate change is perhaps the greatest threat to humanity today and plays out as a cruel engine of myriad forms of injustice, violence and destruction. The effects of climate change from human-made emissions of greenhouse gases are devastating and accelerating; yet are uncertain and uneven both in terms of geography and socio-economic impacts. Emerging from the dynamics of capitalism since the industrial revolution — as well as industrialisation under state-led socialism — the consequences of climate change are especially profound for the countryside and its inhabitants. The book interrogates the narratives and strategies that frame climate change and examines the …

Quantifying Structural Vegetation Change On Arctic Tundra: A Multi-Decadal Study Integrating Remotely Sensed Imagery And Traditional Field Measurements, Anna M. Moser

Graduate Student Theses, Dissertations, & Professional Papers

Arctic regions have experienced an amplified rate of climate warming in recent decades, contributing to well-documented increases in tundra vegetation productivity. Satellite remote sensing has historically played a crucial role in detecting and quantifying trends at regional and biome scales; however, coarse resolution imagery has proven insufficient for capturing fine-scale variability in vegetation response. Considering the spatial heterogeneity of tundra vegetation, high resolution, plot-scale remote sensing observations are necessary. This study couples traditional field measurements with high-resolution unmanned aerial vehicle (UAV) imagery and plane-based aerial photos to quantify changes in vegetation on the North Slope of Alaska over a 28-year …
