Timely and accurate detection of burned areas is crucial for assessing fire damage and contributing to ecosystem recovery efforts. In this study, we propose a framework for detecting fire-affected vegetation anomalies on the basis of a ResNet deep learning (DL) algorithm by merging spectral and textural features (ResNet-IST) and the vegetation abnormal spectral texture index (VASTI). To train the ResNet-IST, a vegetation anomaly dataset was constructed on high-resolution 30 m fire-affected remote sensing images selected from the Global Fire Atlas (GFA) to extract the spectral and textural features. We tested the model to detect fire-affected vegetation in ten study areas …

Geographic Patterns Of Educational Achievement: A Methodological Case Study Of Regression Modeling Approaches, Leokadia Lipien
USF Tampa Graduate Theses and Dissertations
This methodological case study introduces a novel approach to investigate the impact of student, teacher, and geographic factors on the academic achievement of virtual school students in Florida. Traditional linear regression models, and even multilevel models, often overlook spatial dependencies, which can lead to biased estimates and incomplete inferences. This research addresses this limitation by comparing a cross-classified multilevel model (CCMM) with a novel cross-classified spatial model (CCSM) that incorporates coefficients from geographically weighted regression (GWR). Utilizing secondary data from a statewide virtual school, including student demographics, teacher characteristics, and standardized test scores, along with U.S. Census Bureau data, the …

Optimizing Future Cropland Allocation In A Biodiverse Savanna By Integrating Agricultural Benefits And Ecological Costs, Lei Song, Amy Frazier, Christopher L. Crawford, Anna B. Estes, Lyndon Estes
Geography
Context: Producing sufficient food to meet a growing population while minimizing the ecological impacts of agricultural expansion is a major global challenge, particularly in biodiverse regions where cropland development threatens ecological integrity. Tanzania exemplifies this tension, as efforts to meet food security goals often conflict with the conservation of its rich ecosystems. Objectives: We aimed to optimize the spatial allocation of future cropland to balance agricultural productivity with key ecological objectives. Additionally, we evaluated alternative strategies for meeting future food demands, such as increasing cropland usage intensity and expanding high-yield crops, to reduce pressure for further cropland expansion. Methods: We …

A Gis Method To Summarize Changes Among Classes During A Time Series With An Application To Land Cover In Western Bahia, Brazil, Robert Gilmore Pontius, Antonio Victor Galvão Da Fonseca
Geography
Petabytes of raster maps exist that show numerous classes across a series of many time points. Scientists need new methods to summarize the temporal changes so scientists can understand broad patterns and have guidance for how to look deeper into particular places, trajectories, classes, and time intervals. Our manuscript addresses this need by presenting an innovative method that summarizes the temporal changes in terms of a map of four trajectories and bar charts of five components: quantity, allocation exchange, allocation shift, alternation exchange, and alternation shift. An application illustrates the method using 16 land cover classes at 7 time points …

Seeing Beyond The State: Private Sector-Led Smart City Governance In Bsd City, Indonesia, Prerona Das, Orlando Woods, Lily Kong
Research Collection College of Integrative Studies
In recent decades new cities have sprung up at a rapid pace, aided by private sector funding (Hogan et al., 2012). Within the realm of smart city development, private sector influence over urban governance has substantially increased, particularly through Public-Private Partnerships (PPPs). However, in Indonesia, there is an emerging trend of the private sector exerting significant control over ‘independent’ greenfield smart cities beyond state-led frameworks. This paper develops the idea of seeing beyond the state which involves looking past conventional state-centered approaches to urban governance. It considers instead how power and control are exercised outside or beyond the usual boundaries …

Analyzing Sea Level Rise Scenarios Impact On The Mobility, Infrastructures, Environment Of Abu Dhabi And Defining Solutions By Creating A Digital Twin Using Gis And Game Engine, Justine Sylviane Lucie Sarrau
Thesis/ Dissertation Defenses
This dissertation is concerned with the potential impact of future sea level rise scenarios on the city of Abu Dhabi. With climate change, many coastal towns are at risk of experiencing this type of natural hazard. Currently, no precise scenario simulations have been developed, mainly related to the use of low spatial resolution elevation data. Additionally, the difficulty in understanding the real impacts persists when relying solely on traditional cartography and GIS methods. This dissertation mainly aims to take a further step by offering a new approach, which involves creating a real-time 3D simulation and dynamic flowing water. This is …

Toward A Feminist Geo-Legal Reading: Us Country-Of-Origin Information In Asylum Adjudication, Malene H. Jacobsen, Austin Crane, Elise Dosch
Faculty Publications
In this article, we offer what we call ‘a feminist geo-legal reading’ of documents used in spaces and practices of law. Legal cases and decisions are often based on different legal and non-legal documents, including laws, explanatory memorandums, testimonies, medical reports, and so forth. In contemporary asylum adjudication, country-of-origin information reports (COIs) have become a crucial source of authoritative evidence as asylum officers and immigration judges use these reports in their determination of a person's need for and right to protection. However, there is no straight line from COIs' substance to the prevailing authority that they command within asylum adjudication. …

Rewilding The Built Environment: Navigating Economic, Political, And Social Barriers To Urban Ecological Restoration, Carly E. Smith
PANDION: The Osprey Journal of Research and Ideas
Urban rewilding offers a nature-based approach to restoring ecological processes in cities while advancing climate resilience, biodiversity, and public well-being. Unlike conventional green infrastructure, rewilding allows ecosystems to develop with minimal intervention, emphasizing succession, complexity, and long-term adaptability. This paper examines the political, economic, and social factors that frame how rewilding is understood and implemented in urban planning. Governmental frameworks often prioritize order, predictability, and short-term results, making it difficult to accommodate the uncertainty and ecological complexity that rewilding requires. Economic models struggle to capture its long-term value, frequently overlooking ecosystem services or reconciling competing land uses. Social perceptions of …

Repairing Epistemic Injustice And Loss In The Era Of Climate Coloniality, Farhana Sultana
Geography and the Environment - All Scholarship
Climate change intensifies existing inequities, disproportionately impacting marginalised populations, particularly in the Global South and Indigenous communities. This is maintained through inequitable global climate governance, policies and solutions. The paper argues that climate coloniality, the complex entanglements of colonial legacies with contemporary climate and ecological changes, operates through systemic knowledge-based marginalisation or epistemic injustice, serving as a key mechanism in the uneven production and distribution of climate harms. Beyond the more commonly discussed material dimensions of loss and damage, epistemic injustices arise from silencing critical voices and devaluing knowledge systems. The paper extends the scope of loss and damage debates …

Despite decades of investment in agricultural research and rice development, the Philippines continues to face stagnation in domestic rice production. This persistent trend, occurring despite a sizable arable land base and large rural workforce, has contributed to the country’s growing reliance on rice imports to meet national food needs. In response, the government has implemented a tariff-based import system designed to fund domestic productivity improvements. While previous studies have explored the technical and environmental constraints affecting rice production, such as irrigation shortfalls, land degradation, and climate variability, few have examined recent national trends using regionally disaggregated data alongside qualitative insights. …

Individuals’ Perspectives On The Location Of Tornado Alley And Their Decision To Take Shelter, Sara R. Lippi, David A. Call, Nathan M. Hitchens
The Geographical Bulletin
This paper examines how individual’s views of their location relative to Tornado Alley affects their decision to shelter. Tornado Alley is a common term promoted by the media as an area of the United States thought to have the greatest tornado intensity and frequency. While this term is now considered anachronistic by meteorologists, it is a colloquial term that individuals might use to guide tornado safety-related decisions. For this study, an online survey was used to identify where respondents believed Tornado Alley to be and how their location relative to it affected their decision to take shelter. It was found …
