Urban Forests And Their Potential To Combat Food Insecurity: Analyzing Street Trees In Baltimore, Md For Their Edibility, Victoria Bearden

Environment and Sustainability Honors Papers

Food insecure environments, in which residents lack consistent access to nutritious food materials, can occur in urban settings. Literature on urban forests suggests that trees can provide a range of provisioning ecosystem services, including edible uses. We consider this to determine if street trees in Baltimore, Maryland have the potential to provide nutritious food materials to address food insecurity in Healthy Food Priority Areas (HFPA), designated by Johns Hopkins Center for a Livable Future. Our analysis utilizes the Plants For a Future database and the geospatial hotspot analysis tool in Esri’s ArcMap to determine the edible quality ratings (EQR) of …

A Street-Based Simulation Approach To Evaluating Crime Theories And Deterrence Efficacy In Baton Rouge, Louisiana, Shaun Edward Williams

LSU Doctoral Dissertations

Criminology of place and deterrence strategy evaluations share separate yet similar paths towards incorporating microgeographic units of analysis within deterrence strategies. These transitions have been underway since Weisburd’s 2015 criminology of place work and Kennedy’s 1997 Ceasefire publication for deterrence strategy evaluation. Rather than purely theoretical or practical challenges serving as agents of change, scale appropriateness can arguably be pinpointed as the foundation for change in both areas. Microplace offers improved insight into the study of crime and place dominated by areal designs. This status quo has hampered evaluation but has not slowed the flow of resources to support strategy …

History To Data: Converting Topographic Maps Into Digital Elevation Models, Briar Pierce, Eileen G. Ernenwein

Appalachian Student Research Forum

Studying past landscapes existing before the modern era (pre-1945) carries great difficulty. Historical maps can offer insight to researchers, but the two-dimensional cartographic features on these maps remain largely inaccessible for geospatial analyses. This study investigates the idea of unlocking the data within historical maps to be utilized by Geographic Information Systems (GIS). To realize this goal, the cartographic features must be extracted and converted into digital vector (line) and raster (grid) data. For the purposes of this study, we focus on the extraction of elevation contour lines in United States Geological Survey (USGS) historical topographic maps. These lines are …

Method one's objectives are to find an optimal location(s) for a potential Norfolk day service facility based on 1) proximity to social and health services, 2) proximity to a neighborhood that would most benefit from a day center, and …

The Role Of Physical Geographic Features In Video Games, Dexter Ferguson

Theses

This thesis examines how physical geographic features affect individuals when interacting with video game environments. There are very few studies on the geography of video games. I aim to bridge the gap between game studies and geography, a naturally occurring link. The observation of elements such as the geography of an area is critical when exploring an individual’s perception of a video game environment. Individuals interact with the geography of their location on a day-to-day basis, whether it be physical or human geography; how they can relate a video game’s geography to the real world dramatically affects their immersion. An …

Safe Water For All: A Multi-Modal Approach To North Alabama's Water Resources, Elijah Walker

Theses

Environmental degradation is a destructive force produced by the human disturbance of pollution. It is a phenomenon that gradually evolves landscapes over time resulting in irreversible outcomes. Environmental degradation physically affects spaces’ resources, objects, and inhabiting humans. This study observes the impacts of pollution beyond physical boundaries and how it affects human identity/sense of place through the utilization of geographic information systems. Specifically, it examines cultural identity developed through human experiences and connections to landscapes containing water resources. Following, pollution contaminates water resources disrupting experiences and connections thus causing the cultural identity to disappear. The case study applied to this …

Drivers And Distribution Of Solar Pv In New York State, Jessica Stretton

Theses and Dissertations

This paper investigates the drivers and distribution of solar photovoltaic (PV) installations in New York State using statistical analysis and GIS. Rooftop residential solar projects were found across the state but were most heavily concentrated around the cities of New York, Schenectady and Ithaca. Larger scale, ground-mounted projects were located upstate and the less densely populated areas of the Lower Hudson Valley. Although there were more projects and kW generation downstate, individual solar PV installations were more likely to be larger in size upstate.

Exploring The Relationship Between Historical Redlining And Place-Based Reproductive Health Inequities: A Qualitative Gis Approach, Kristi L. Roybal

Electronic Theses and Dissertations

Individual-level risk factors and characteristics do not fully explain racial, ethnic, and socioeconomic inequities in preterm birth in the United States, and evidence suggests that medical advancements, increased access to prenatal care, and high per-capita spending on health care have done little to reduce these inequities. Health inequities research has shifted its attention from individual-level factors that influence health outcomes to the social determinants of health. Neighborhoods, considered an important upstream social determinant of health, can influence health outcomes through their social, service, and physical environments, and have been consistently linked to birth outcomes. Despite increased attention to neighborhood influences …

Decolonizing The Map: Indigenous Maps And Gis, Henry Osborne Beimers

All Graduate Theses, Dissertations, and Other Capstone Projects

Indigenous mapping practices have yet to be widely considered by geographers outside of a historical context. In this paper I critique the geographic research paradigm through the lens of settler colonial and critical cartographic theory. I present evidence for the value of Indigenous mapping practices through a historical-critical GIS analysis of two Indigenous maps, and a creation of a story map to present those results. Finally, I suggest future routes to integrate digital mapping and Indigenous mapping practices, for pedagogy, and for preserving cultural resources, language, land, and traditional Indigenous knowledge.

Municipal Solutions To Climate Change ; A Case Study Of Stream Daylighting In Suffolk County, New York, Madison Hrysko

Legacy Theses & Dissertations (2009 - 2024)

During the 1950’s and 1960’s Suffolk County, New York experienced rapid urbanization and development. To pave way for infrastructure, hydrological modifications were made to the land including the burial of naturally flowing streams. Daylighting streams is the nature-based process of bringing buried streams back to the surface. In turn, restoring ecosystem services, increasing local resilience to climate change impacts, and expanding biodiversity. Minimal research has been done using GIS technology alongside a set of criteria to select best fit streams for daylighting. This thesis aims to fill that gap by identifying best and second-best fit streams for daylighting in Suffolk …

Sauls, Anthony J. Bebbington, Denise Humphreys Bebbington, Avecita Chicchon, Pilar Delpino Marimón, Oscar Diaz, Susanna Hecht, Susan Kandel, Tracey Osborne, Rebecca Ray, Madelyn Rivera, John Rogan, Viviana Zalles

Geography

Despite the importance of preserving contiguous tropical forest areas to maintain biodiversity and terrestrial carbon stocks, methodological challenges continue to hinder broad-scale analysis of threats to these forests. Emerging Hot Spot Analysis (EHSA) is a spatial-statistical method that conveys complex information about the temporal dynamics of deforestation across a range of moderate to coarse spatial scales. Using Global Forest Change (GFC) data as inputs, EHSA produces spatially comprehensive, gridded outputs that represent a standardized, reproduceable way to instantiate contiguous forest tracts as spatial objects. Doing so allows aggregation of other GFC-derived values and analysis of alternative geographic configurations besides sub-national …

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 …

Data-Driven Operational And Safety Analysis Of Emerging Shared Electric Scooter Systems, Qingyu Ma

Computational Modeling & Simulation Engineering Theses & Dissertations

The rapid rise of shared electric scooter (E-Scooter) systems offers many urban areas a new micro-mobility solution. The portable and flexible characteristics have made E-Scooters a competitive mode for short-distance trips. Compared to other modes such as bikes, E-Scooters allow riders to freely ride on different facilities such as streets, sidewalks, and bike lanes. However, sharing lanes with vehicles and other users tends to cause safety issues for riding E-Scooters. Conventional methods are often not applicable for analyzing such safety issues because well-archived historical crash records are not commonly available for emerging E-Scooters.

Perceiving the growth of such a micro-mobility …

Spatial-Temporal Modeling Of Agricultural Water Surface Features In Northeastern Arkansas., Daniel Dewayne Shults

Student Theses and Dissertations

The Mississippi River Valley Alluvial Aquifer (MRVA) has been the primary source of irrigation water in Northeastern Arkansas since the early 1900s. Over time the MRVA water level has declined due to over-pumping of farm wells and water restrictive geology. The aquifer is expected to continue declining but with water conservation strategies in place, this vital resource could be preserved for future farmers. This thesis investigated using remotely sensed data to assess landforms associated with agricultural water conservation across Northeastern Arkansas. The remotely sensed data proved to be useful at creating temporal assessments of pre-existing irrigation reservoirs, identifying new irrigation …

Examining The Effects Of Hydrology And Reclaimed Water Application On Nutrient Retention In Wetlaculture Mesocosms In Southwest Florida, Andrew Wilson

USF Tampa Graduate Theses and Dissertations

The substantial increase among agricultural and urban land use over the past century is widely regarded as the leading cause in a variety of negative environmental impacts, particularly regarding eutrophication of both salt and fresh surface waters. Usage of both synthetic and natural fertilizers on agricultural fields and residential lawns has increased significantly in order to achieve maximum crop yield and green lawns. The nitrogen and phosphorus in these fertilizers inevitably run off the landscape and into downstream surface waters. The geographic scale of this issue makes it a challenge to overcome, as targeting specific sources/polluters is nearly impossible. Landscape-scale …
