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 Change

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 …

Open-Source Based Change Pattern Analysis Of Urban Green Spaces Using Landscape Metrics, Mohammad Anwar Alattar

The Geographical Bulletin

A growing number of studies have been conducted on urban green spaces (UGSs), given their essential role in mitigating urbanization externalities. The current available methods for acquiring and analyzing UGSs data suffer from several limitations. For example, free satellite imagery exhibits pixel distortion and fails to account for fine-grained structure such as accurate geometry or size. Moreover, official UGSs datasets are typically updated periodically, not continuously. This work provides a Python-derived open-source based analysis for acquiring, modeling and analyzing UGSs change patterns using landscape metrics. To demonstrate the feasibility of the proposed approach, it is applied on the New York …

People, Place, And Planet: Global Review Of Use-Inspired Research On Water-Related Ecosystem Services In Urban Wetlands, Jason Sauer, Heejun Chang

Geography Faculty Publications and Presentations

With climate change and urbanization, city planners and developers have increasing interest and practice in constructing, restoring, or incorporating wetlands as forms of green infrastructure to maintain water-related ecosystem services (WES). We reviewed studies that valued in functional or monetary units the water regulation and purification services of urban wetlands around the globe. We used the adaptive management cycle (AMC) as a heuristic to determine the step that a study would represent in the AMC, the connections between the cycle steps that were used or considered, and the stakeholders involved. Additionally, we identified the social, ecological, and/or technological dimension(s) of …

Climate Change, Site Formation, And Indigenous Use Of Coastlines In Barbuda, Isabel C. Rivera-Collazo, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

This article explores the landscape dynamics at the island of Barbuda in the context of changing climate to understand (1) the environmental setting of indigenous settlements; (2) the impacts of current coastal processes; and (3) the potential threats moving forward toward increasing pressure of climate change. Focusing on the site of Seaview, on the east coast of Barbuda, we use geoarchaeological methods to reconstruct the ancient geomorphological setting, investigate changes post-abandonment, and identify the hazards faced under future sea-level projections. Our study shows that (1) sea level stabilization after the Mid-Holocene allowed the formation of coral reefs, seagrass beds and …

Predicting Groundwater Spring Locations From Topographic And Climatic Data Using Maxent Modeling, Ayten Ece Koc

USF Tampa Graduate Theses and Dissertations

The World Resources Institute reveals that 17 countries face extremely high levels of water stress. Moreover, with increasing population and industrialization, the gap between water supply and demand increases day by day around the world. Groundwater is a key freshwater source, and springs are important resources as they enable to access groundwater. Therefore, it is crucial to monitor, protect, and manage groundwater springs. The first step in spring management is to recognize and define freshwater resources and to determine the locations of groundwater springs that serve as natural discharge points. Traditionally, field studies have been employed to determine the locations …

Projecting The Effects Of Climate Change And Urbanization On Longleaf Pine Stands In The Florida Flatwoods, Lilian Grace Hutchens

Theses and Dissertations

The southeastern United States once held millions of hectares of highly connected longleaf pine ecosystem. In a dramatic range reduction, longleaf pine now occupies less than 5% of its original extent, its remnant patches existing within a matrix of human-dominated land uses. Conservation planning for longleaf pine ecosystems is complicated given the ecosystem’s reliance on fire and the broad spatial and temporal scales at which longleaf pine management must operate. Planning timelines for longleaf pine management extend into the end of the 21st century, a period during which climate, fire regimes, and land cover are all expected to change, influencing …

Unsettling Participation By Foregrounding More-Than-Human Relations In Digital Forests, Michelle Westerlaken, Jennifer Gabrys, Danilo Urzedo, Max Ritts

Geography

The question of who participates in making forest environments usually refers to human stakeholders. Yet forests are constituted through the participation of many other entities. At the same time, digital technologies are increasingly used in participatory projects to measure and monitor forest environments globally. However, such participatory initiatives are often limited to human involvement and overlook how more-than-human entities and relations shape digital and forest processes. To disrupt conventional anthropocentric understandings of participation, this text travels through three different processes of "unsettling"to show how more-than-human entities and relations disrupt, rework, and transform digital participation in and with forests. First, forest …

Multisensory Experiences In Archaeological Landscapes—Sound, Vision, And Movement In Gis And Virtual Reality, Heather Richards-Rissetto, Kristy Primeau,, David E. E. Witt, Graham Goodwin

Department of Anthropology: Faculty Publications

Archaeologists are employing a variety of digital tools to develop new methodological frameworks that combine computational and experiential approaches which is leading to new multisensory research. In this article, we explore vision, sound, and movement at the ancient Maya city of Copan from a multisensory and multiscalar perspective bridging concepts and approaches from different archaeological paradigms. Our methods and interpretations employ theory-inspired variables from proxemics and semiotics to develop a methodological framework that combines computation with sensory perception. Using GIS, 3D, and acoustic tools we create multisensory experiences in VR with spatial sound using an immersive headset (Oculus Rift) and …

Using Extended Two-Step Floating Catchment Area To Map Children’S Level Of Access To Physical Books In West Virginia, Heather A. Maxey

Graduate Theses, Dissertations, and Problem Reports

The state of West Virginia lacked a comprehensive, in-depth analysis of the availability of physical books across the state. Access to reading material is vital to a child’s educational development as well as lifelong learning beyond childhood. To guide policy decisions and planning for outreach which addresses reading levels and beyond, I mapped levels of access stemming from socioeconomic barriers, spatial barriers, and an integrated index of both types of barriers. To map spatial access, I utilized a modified Extended Two-Step Floating Catchment Area model, deriving techniques from Hong et al’s 2023 article addressing access for health care in WV. …

Carnivore And Ungulate Occurrence In A Fire-Prone Region, Sara J. Moriarty-Graves

Cal Poly Humboldt theses and projects

Increasing fire size and severity in the western United States causes changes to ecosystems, species’ habitat use, and interspecific interactions. Wide-ranging carnivore and ungulate mammalian species and their interactions may be influenced by an increase in fire activity in northern California. Depending on the fire characteristics, ungulates may benefit from burned habitat due to an increase in forage availability, while carnivore species may be differentially impacted, but ultimately driven by bottom-up processes from a shift in prey availability. I used a three-step approach to estimate the single-species occupancy of four large mammal species: mountain lion (Puma concolor), coyote …

Comparison Of Water Column Properties Derived From An Autonomous Underwater Vehicle And Satellite Based Sources In Lake Michigan, David Bennion

Master's Theses and Doctoral Dissertations

Autonomous underwater vehicles (AUVs) are an emerging technology increasingly being employed in geoscience and ecosystem research in the Great Lakes, capitalizing on their ability to sample large areas fitted with a variety of sensors. Previous to AUV use, chlorophyll measurements were either collected at discrete locations accessed by boats or derived from satellite remote sensing data. An advantage of AUVs is the ability to detect the presence of subsurface formations such as a deep chlorophyll layer or directly measure features such as the extent of the photic zone, which provides the opportunity to compare these in situ measured features to …

A Gis Suitability Model Evaluating Habitat Characteristics Influencing Beaver (Castor Canadensis) Lodge Site Selection And Lodge Occupancy In Central Adirondacks, New York, Amanda K. Jacobs

Theses - ALL

The North American beaver (Castor canadensis) represents a quintessential example of an "ecosystem engineer." Yet the species' landscape-scale impacts on hydrology, geomorphology, and ecosystem ecology are not uniformly distributed through landscapes or time. Understanding beaver lodge site selection and lodge fidelity through time can help to predict where the greatest effects of beaver activity may occur. In this research project, I seek to understand the relationships between beaver habitat suitability, the habitat variables that currently define suitable areas, and lodge occupancy over time. Using Geographic Information Systems (GIS) to model habitat suitability, I use hydrologic, vegetative, and physiographic variables to …

Efficiency In The Upper Deschutes Basin: Understanding The Hydrosocial Implications Of Irrigation Canal Piping, Rebecca Anderson

Dissertations and Theses

In response to water scarcity, irrigation efficiency projects aim to conserve water for in-stream flow and agricultural use. Piping irrigation canals is a common irrigation efficiency method which reduces the loss of incidental recharge, resulting in trade-offs within a hydrosocial system. Few studies have focused on the consequences of canal piping and none have integrated a critical analysis of the social factors involved in deciding what constitutes 'efficient' water use. This study seeks to fill this gap by combining natural and social science to give attention to the scales and perspectives involved in irrigation efficiency canal piping and the material …

"We've Created Cheap Energy Off The Backs Of Salmon": Dam Removal Politics And Alliances In The Lower Snake River Basin, Krista Harrington

Dissertations and Theses

Dams, once considered by many to be good for water development in the Western U.S., might not be a part of a climate resilient future. Dams have come under increasing scrutiny due to undesirable ecological implications. Although dam removal proposals are growingly popular in recent decades, they are controversial since they impact different stakeholders in different ways. In the Pacific Northwest, the Lower four Snake River dams have long been criticized for their negative impacts on salmon. In February 2021, US Congressman Mike Simpson (R-Idaho) proposed a comprehensive framework to deconstruct the Lower four Snake River dams as an attempt …

Constructing The Eastern Coyote: A Temporal Analysis Of The Scientific And Social Production Of A Controversial Northeastern Canid, Kayleigh Moses

Senior Theses and Projects

Eastern coyotes (Canis latrans var) have confounded the scientific and social boundaries established by postcolonial United States. The first eastern coyote specimen on record comes from Otis, Massachusetts in 1957. At the time, this unknown and unnamed wolf-like creature sparked fear amongst human residents of the Northeastern United States. Threatened by the presence of this predator, Northeasterners launched coyote killing efforts similar to the eradication campaigns that had previously failed in the Western United States. Today, Massachusetts officials estimate that 11,500 eastern coyotes occupy the state, living amongst people and pets in every county. This abundance of eastern …

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

Fire incident has a great impact on the loss of lives and financial loss due to property damage. Areas with high population density, densely physical building conditions, and irregular building patterns commonly form congested residential slum areas are vulnerable to fire hazards. The capital city of Jakarta is the most populous city in Indonesia and the most densely populated city, with an average of 15,900 people per sq km. In 2019, there was 2,109 fire incident recorded, and nearly 20% of them occurred within the West Jakarta Municipality area. This study investigates the relationship of population density and building density, …

Lake Huron Shoreline Analysis, Shubham Satish Nandanwar

Theses and Dissertations (Comprehensive)

Lake Huron is a popular tourist destination and is home to several businesses and residents. Since the shoreline is dynamic and is subject to change over the years due to several factors such as a change in water level, soil type, human encroachment, etc., these locations tend to encounter floods due to increased water levels and wind speed. This causes erosion and loss to the properties along the shoreline.

This study is based on two areas of interest named Pinery Provincial Park and Sauble Beach which are located on the shoreline of Lake Huron where Pinery Provincial Park is a …

Seeding Resilience: An Examination Of The Impacts Of A Seed Saving Network In Western Montana, Christina Leas

Graduate Student Theses, Dissertations, & Professional Papers

Seed saving, a worldwide practice as old as agriculture, continues even in the context of an increasingly industrialized and globalized agricultural system. While some scholarship has focused on informal seed saving practices that continue to thrive in the global South, few studies have examined the dynamics of these practices in the global North, particularly in the American West. Informal seed saving systems have implications for the resilience of agroecosystems. The concept of resilience has become an important framework for conceptualizing agroecosystems as social-ecological systems, both in scholarship and in policy. However, operationalizing the concept of resilience, particularly in agroecology research, …

Modeling Environmental Factors Related To Drought-Induced Tree Mortality Based On Lidar And Hyperspectral Imagery, Lauren Nicole Sharwood

Dissertations and Theses

Climate change is projected to bring more frequent and prolonged droughts, causing widespread forest die-off. Identifying tree mortality over large spatial extents in response to the most recent California drought will help forest managers and conservationists understand where there may be a greater likelihood of future die-offs. In order to find more at-risk areas, this study evaluated how interacting site-specific topographic, climate, substrate, and stand characteristics mediated tree mortality in the Central Sierra Nevada during the 2012-2016 drought. The author used lidar and hyperspectral imagery provided by the National Ecological Observatory Network to identify individual dead trees using the Random …

Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan

Doctoral Dissertations

Carnivores are distributed widely and threatened by habitat loss, poaching, climate change, and disease. They are considered integral to ecosystem function through their direct and indirect interactions with species at different trophic levels. Given the importance of carnivores, it is of high conservation priority to understand the processes driving carnivore assemblages in different systems. It is thus essential to determine the abiotic and biotic drivers of carnivore community composition at different spatial scales and address the following questions: (i) What factors influence carnivore community composition and diversity? (ii) How do the factors influencing carnivore communities vary across spatial and temporal …

Weedy Relations: Narratives Of Invasion And Intimacy With Tamarisk In The Chihuahuan Desert, Shannon S. Pepper

Geography ETDs

Tamarix spp., also known as salt cedar or tamarisk, is a shrub that has garnered a notorious reputation in North America as an invasive plant, with widespread policy and research advocating for its eradication in the Southwest U.S. and Northern Mexico. This study examines both governmental conservation documents and news articles to investigate narrative trends on tamarisk in the Southwestern U.S. and Northern Mexico as a contiguous region (the Chihuahuan Desert), expanding on current research to include transborder effects on the perception and management of introduced species. This paper asks: In the last 25 years, how has the movement, …

Using Aeolian Depositional Lag Times To Relate Dune Vegetation And Topographic Change, Jacquelyn Brianna Ferguson

Theses and Dissertations

Sediment deposition impacts dune morphology and is a product of many environmental factors. Dune vegetation is related to post-storm dune recovery and morphology. Though it is widely agreed that vegetation impacts sediment deposition, this relationship has not yet been quantified in the field. This research was conducted at Isle of Palms, a meso-tidal barrier island in South Carolina, where we collected topographic and vegetation data over an incipient foredune. Vegetation data were classified by functional type (dune-builder or dune-stabilizer) or land cover (sand, wrack). We identified land cover changes resulting in greater surface roughness. To relate land cover change to …

Sheep Replace Pronghorn: An Environmental History Of The Mono Basin, Robert B. Marks

Eastern Sierra History Journal

This article examines the ways in which the hunting-gathering people of the Mono Basin lived before their way of life and environment was overturned by the nineteenth-century arrival of Euro-American settlers with vastly different ways of interacting with the environment. And it tracks some of these alterations by tracking when and how sheep replaced pronghorns.

Disrupted Identities And Forced Nomads: A Post-Disaster Legacy Of Neocolonialism In The Island Of Barbuda, Lesser Antilles, Sophia Perdikaris, Rebecca Boger, Edith Gonzalez, Emira Ibrahimpašić, Jennifer D. Adams

School of Global Integrative Studies: Faculty Publications

In the aftermath of the forced evacuation of the island of Barbuda due to Hurricane Irma, the Barbudan people have experienced an exile and return to a ‘new’ geographical, political, and economic context, albeit on the same island. With the specter of climate change and the potential impacts on island communities and nations, we use Barbuda, sister island of Antigua in the Lesser Antilles, to examine the trajectory of nomadic identities as they navigate changes that threaten contemporary land relationships and culture. Since its first permanent settlement in the 17th Century, the island geography of Barbuda has been fundamental to …

An Assessment Of Kentucky Birth Records, Focusing On Early-Onset Hypertensive Disorders Of Pregnancy, Environmental Metal Exposures, And Geocoding Precision, 2008-2017, Courtney J. Walker

Theses and Dissertations--Epidemiology and Biostatistics

Using live and stillbirth records from Kentucky (2008-2017), this dissertation assessed the county-level prevalence and geospatial patterns of early-onset hypertensive disorders of pregnancy (eHDP); examined the geocoding precision of addresses recorded on birth records, and evaluated the association between individual risk factors and environmental metal exposures on eHDP prevalence. After adjusting for maternal demographic factors and pre-existing health conditions, we observed that eHDP prevalence was 38% higher (aPR=1.38, 95%CI:1.16, 1.64) in counties with the highest prevalence of married women (> 53.8%) compared to lower prevalence areas (31.6%) had a 20% higher prevalence of eHDP(aPR=1.20, 95%CI:1.00, 1.44) compared to counties with …

The Sea Will Rise, Barbuda Will Survive: Environment And Time Consciousness, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

In this article, we examine the link between environmental consciousnesses and time consciousness. We argue that the way people think about time shapes their experience of climate change threats. We contrast western hegemonic concepts of time—the Gregorian Calendar, the Dooms Day Clock, linear time—with the way Barbudans of Antigua and Barbuda, an island nation in the Caribbean experience time—cyclical, through boom and bust cycles. We found that this boom and bust framework was indeed supported by climate change and weather experiences on the island—hurricanes, droughts, changes in the lagoons—as well as economic experiences—cargo boat delays bringing supplies, paycheck delays. By …

Using Soil Geospatial Properties And Environments To Explore Microbial Diversity, Sharon Faye Smith

Graduate Theses and Dissertations

Soil microorganisms help maintain nutrient cycling, control carbon sequestration, impact plant productivity, and influence several soil chemical and physical properties; yet, the processes that control the microbial composition of soil and how environmental changes may affect the composition and activity of these organisms at different scales remains a difficult and intriguing puzzle for soil scientists, ecologists, and modelers. Wetlands are endangered and important ecosystems that provide several services, which are directly linked to soil function. However, few wetland assessments consider the soil environment and microbial ecology. Linking soil microbial community composition and distribution patterns to soil physio-chemical properties would provide …
