Using Gis-Based Land Use Strategies To Minimize The Impacts Of Urbanization On Agricultural Land And Forest Cover: Case Study Of The City Of Limbe, Cameroon, Lucy Ebude Deba Enomah

USF Tampa Graduate Theses and Dissertations

Urbanization is one of the most dominant phenomena of the 21st century; it is propelled by natural growth and rural-to-urban migration. This latter is typically a product of rural residents moving to urban centres in search of economic opportunities. This phenomenon is accompanied by immense land use and cover changes – predominantly agricultural and forest lands to urban land uses such as buildings and infrastructure. The goal of this research was to contribute to efforts to minimize the impacts of urbanization on agricultural land and forest cover in Limbe, Cameroon, and to develop GIS-based strategies to allocate suitable land for …

Many humans live in large, complex political centers, composed of multi-scalar communities including neighborhoods and districts. Both today and in the past, neighborhoods form a fundamental part of cities and are defined by their spatial, architectural, and material elements. Neighborhoods existed in ancient centers of various scales, and multiple methods have been employed to identify ancient neighborhoods in archaeological contexts. However, the use of different methods for neighborhood identification within the same spatiotemporal setting results in challenges for comparisons within and between ancient societies. Here, we focus on using a single method—combining Average Nearest Neighbor (ANN) and Kernel Density (KD) …

Modeling Airport Catchment Areas: Using Spatial Analysis Approach, Sitong Chen

Allen, Christopher Davis, Alexander Garnand, Heather Richter, Prachi P. Chaven, Leslie Hoglund, Jill Comess, Matthew Herman, Brian Martin, Cynthia Romero

Political Science & Geography Faculty Publications

Background: Food is not equitably available. Deficiencies and generalizations limit national datasets, food security assessments, and interventions. Additional neighborhood level studies are needed to develop a scalable and transferable process to complement national and internationally comparative data sets with timely, granular, nuanced data. Participatory geographic information systems (PGIS) offer a means to address these issues by digitizing local knowledge.

Methods: The objectives of this study were two-fold: (i) identify granular locations missing from food source and risk datasets and (ii) examine the relation between the spatial, socio-economic, and agency contributors to food security. Twenty-nine subject matter experts from three cities …

Shifting Geopolitics: Reimagining Globalization And Spatial Representation In The Post Covid-19 Era, Victoria H. Bergström

The Journal of International Relations, Peace Studies, and Development

Abstract: Since the emergence of the COVID-19 pandemic, the utilisation of maps has been at the forefront. Maps have informed policymakers, governments, and citizens of the distribution and spread of the disease. Although these maps have been used for various purposes, from border closures to curfews, there is an inherent danger in this widespread usage. Aside from the intricacy of these spatial representations, these widely distributed representations encourage isolationism and the reconception of borders in an increasingly globalised world. Furthermore, new connectivities through digital means have created a potential solution to international exchanges amidst physical limitations. Nevertheless, elitism prevents the …

Using these findings, an economic assessment was …

Multi-Decadal Analysis Of Remotely Sensed Vegetation Change In Berea College Forest - Seasonality Of Forest Patterns Using Remote Sensing, Jacob Foushee

The Cardinal Edge

Satellite imagery is a practical and valuable tool for monitoring vegetation condition in forests. The longevity of the USGS/NASA Landsat program along with its medium spatial resolution (30m) gives researchers the ability to make informed statements on land cover generally, and specifically on aspects such as forest conditions. The Landsat program’s nearly 50-year archive of imagery show how Earth’s surface has changed through modern development and how these developments have influenced forests. Google Earth Engine (GEE) is a cloud-based repository of satellite imagery dating as far back as the 1970s. This study utilizes Landsat 5-8 imagery from GEE to calculate …

Minimizing Surface Run-Off, Improving Underground Water Recharging, And On-Site Rain Harvesting In The Kathmandu Valley, Ambika P. Adhikari, Keshav Bhattarai

Himalayan Research Papers Archive

Nepal's political institutions and administrative units were thoroughly restructured in 2015 with the promulgation of the new Constitution. Several rural areas were combined to meet the definition of urban threshold criteria to classify rural areas into urban categories. Accordingly, over 3,900 local political and administrative units were amalgamated into 753 units, of which, 293 units are classified as urban. Within these newly defined urban areas, many natural environments have been converted into impervious surfaces such as paved roads, sidewalks, and building roofs. These impervious surfaces have drastically increased the amount of surface run-offs-often termed as "urban floods"--under increasing precipitation caused …

Context For Reproducibility And Replicability In Geospatial Unmanned Aircraft Systems, Cassandra Howe, Jason A. Tullis

Geosciences Faculty Publications and Presentations

Multiple scientific disciplines face a so-called crisis of reproducibility and replicability (R&R) in which the validity of methodologies is questioned due to an inability to confirm experimental results. Trust in information technology (IT)-intensive workflows within geographic information science (GIScience), remote sensing, and photogrammetry depends on solutions to R&R challenges affecting multiple computationally driven disciplines. To date, there have only been very limited efforts to overcome R&R-related issues in remote sensing workflows in general, let alone those tied to unmanned aircraft systems (UAS) as a disruptive technology. This review identifies key barriers to, and suggests best practices for, R&R in geospatial …

Centers Of Community: A Spatial Analysis Of The Mid-19th Century Populaton Residing On Beacon Hill, Boston, Ma, Justin Malcolm

Graduate Masters Theses

The first Black church constructed in Boston, and the oldest extant Black church building in America, the African Meeting House was located on the North Slope of Beacon Hill; the predominant residence of Boston’s Black population during the nineteenth century. The African Meeting House has been the subject of several important archaeological investigations. In 1840, a schism within the African Meeting House congregation resulted in the establishment of the Twelfth Baptist Church. Historical contexts suggest that this neighborhood was highly segregated. A geographic and statistical analysis of the unique 1850 Boston City Census, which was made to yield spatial contexts …

The field of health geographics is rapidly growing in its methods and epistemologies. This is a review of the open-source journal International Journal of Health Geographics, and the trends in disease surveillance over ten years (2009-2018). Drawing from research review methodologies, we wrote a Python script to quantify research trends within the field of geographic disease surveillance, finding many articles focusing on population health, techniques of GIS, qualitative techniques, and geospatial technology for health monitoring. This was foundational in conducting an in-depth qualitative lexical analysis of article content and epistemologies. Overall, we concluded that over the time period, the …

An Integrated Gis & Flood Vulnerability Index Approach To Evaluating Risk & Environmental Equity In Urban Karst Communities, Chloe Cooper

Masters Theses & Specialist Projects

This study examines how the usage of an integrated GIS (Geographic Information Systems), flood vulnerability assessment, and management approaches can aid in hazard response planning in karst groundwater systems, particularly in urban environments. In order to also better understand the impacts of flood events on socially vulnerable groups, this research was focused on historically excluded communities. Additionally, place-based vulnerabilities were primarily assessed based upon three main factors in the vulnerability framework and how these components intersect: social, environmental conditions, and economic. By understanding which areas of the City of Bowling Green, an iconic urban karst area, are most vulnerable and …

Changes Of Winter Severity In Arkansas During 1901-2100, Christian Garcia

Graduate Theses and Dissertations

The objective of this study was to quantify the winter severity in a way that was reproduceable and easy to understand. The Accumulated Winter Severity Seasonal Index (AWSSI) was chosen for this reason and was used to quantify winter severity by season across the state of Arkansas. The variables that go into the AWSSI calculation are maximum daily temperature, minimum daily temperature, daily snowfall, and daily snow depth. When the snowfall and snow depth were missing, they can be estimated using daily temperature and precipitation. Then the estimated snowfall and snow depth can be subsequently used to quantify the winter …

Crime Attractors In Sin City? A Pre/Post Test Of Crime Patterns And Police Enforcement Around Recreational Marijuana Facilities, Joshua Donnelly

UNLV Theses, Dissertations, Professional Papers, and Capstones

The federalist system in the United States has created criminal opportunities within jurisdictions that have approved recreational marijuana facilities (RMFs). These facilities have characteristics that are attractive for motivated offenders including marijuana and marijuana-related tangible goods. Through ArcGIS, this research examined the crime patterns and police enforcement patterns that occurred within a 288-meter street-network buffer around RMFs through a pre/post-test exploratory design in the Las Vegas area. The time periods examined were 2015 to 2016 (pre-legalization), and 2018 to 2019 (post-legalization). Calls for service data were used to demonstrate both crime and enforcement patterns. Furthermore, facilities were classified into “local …

Creating A Public Space For Georeferencing Sanborn Maps: A Louisiana Case Study, Adam Cox

LSU Master's Theses

As institutional archives digitize their historical map collections and make them publicly available online, new methods for engaging with these materials emerge. Georeferencing the maps transforms their content from static images to dynamic map overlays, and allows for the extraction of geographic data like building footprints or place name coordinates. Many organizations have turned to crowdsourcing to georeference their large holdings, and this thesis approaches crowdsourced georeferencing from the perspective of participatory heritage, taking much inspiration from the idea of the archival commons. To test these ideas, a new extension was created for GeoNode—an open source geospatial content management system—that …
