Ecological Marginalization And Hill Tribe Security In Northern Thailand, Richard A. Crooker
Ecological Marginalization And Hill Tribe Security In Northern Thailand, Richard A. Crooker
The Geographical Bulletin
In recent decades, Thai elites have ecologically marginalized hill tribe farmers in northern Thailand. A region-wide population boom has fueled a ‘land grab’ by the elites and forced hill tribe farmers to live on less land with few off-farm options. The marginalized farmers are less secure in their livelihoods, and as a result, there has been conflict over resources between them and governmental authorities and ethnic Thais. This paper analyzes the hill tribes’ marginalization in order to assess the risk of heightened social conflict in the region. I chose hill tribe villages in the Mae Sa Valley as a “best-case” …
Reel Racing: The Geography Of The United States Lawn Mower Racing Association, H. Jason Combs
Reel Racing: The Geography Of The United States Lawn Mower Racing Association, H. Jason Combs
The Geographical Bulletin
The United States Lawn Mower Racing Association (USLMRA) formed on April Fools’ Day 1992 and now has approximately 500 members and a national racing circuit. This paper examines the geography of the USLMRA as well as the reasons for its expansion. Professional lawn mower racing’s popularity is somewhat in response to NASCAR’s commercialization and nationalization efforts. Lawn mower racing is more affordable than stock car racing and provides an outlet for many adrenaline-enriched and mechanically inclined individuals. The national circuit runs through traditional stock car country—from Texas and Florida to Illinois, Wisconsin, and Ohio. The majority of USLMRA members and …

Environment And Security Conflicts: The U.S. Military In Okinawa, Jonathan Taylor
Environment And Security Conflicts: The U.S. Military In Okinawa, Jonathan Taylor
The Geographical Bulletin
This paper explores the effects of ongoing environmental issues related to U.S. military bases in Okinawa. Okinawa’s history, particularly the damage it suffered during World War II has led to an active anti-military movement on the island. The U.S. bases exist in a context of anti-military and environmental movements which seek to dislodge the bases from their current location. At the same time the U.S. military bases have had both direct and indirect effects upon Okinawa’s environment: some positive, though many negative. Some steps the U.S. military could take to lessen its environmental impacts upon Okinawa are suggested.

The Power Of Place: Geography, Destiny, And Globalization’S Rough Landscape, By Harm De Blij, James Lowry
The Power Of Place: Geography, Destiny, And Globalization’S Rough Landscape, By Harm De Blij, James Lowry
The Geographical Bulletin
I have come to expect a great deal from Harm de Blij over the years and he has always delivered. So, when I was presented the opportunity to review this new look at globalization from the de Blij perspective I jumped at the chance. The purpose of The Power of Place is to examine the many assertions of a flattening of the earth; of the globalization we are constantly being told is leading us to a loss of regional cultures. So how does de Blij accomplish this task considering the flattening of the earth has been widely recognized as gospel? …
Spring Valley, Washington Dc: Changing Land Use And Demographics From 1900-2000, Benefsheh D. Verell
Spring Valley, Washington Dc: Changing Land Use And Demographics From 1900-2000, Benefsheh D. Verell
The Geographical Bulletin
Spring Valley, located in northwest Washington D.C., has had a dynamic land use history, changing from farmland to military base to residential development during the span of one hundred years. The development and marketing of Spring Valley in the 1930s and 1940s reflects the changing socioeconomics and settlement patterns of D.C. The data suggest a “white flight” out of the inner-city neighborhoods to Spring Valley and the surrounding suburbs. Additionally, Spring Valley, as a Formerly Used Defense Site, presents environmental hazards to the current residential community. The Army’s response to this hazard demonstrates changes in military environmental policies from nonexistent …
Predicting Paths Of Atlantic Tropical Cyclones Using Monthly Surface Pressure Data, P. Grady Dixon, Michael E. Brown, W. Michael Carter, W. Scott Gunter, Kelsey N. Scheitlin
Predicting Paths Of Atlantic Tropical Cyclones Using Monthly Surface Pressure Data, P. Grady Dixon, Michael E. Brown, W. Michael Carter, W. Scott Gunter, Kelsey N. Scheitlin
The Geographical Bulletin
Previous research has had some success in predicting likely tracks of tropical cyclones in the Atlantic basin using North Atlantic Oscillation (NAO) anomalies (above or below average values) during preceding months. This paper expands on this research by incorporating other surface pressure values as independent variables as alluded to by some of the earliest NAO research. We examine monthly sea-level-pressure (SLP) data from Reykjavik (Iceland), Cape Hatteras (North Carolina), and Nassau (Bahamas), along with NAO index anomalies, to see if they can be used to predict future paths and landfall locations of Atlantic tropical cyclones during the period 1970–2005. Average …
Remote Sensing Quantification Of Wetland Habitat Change In South Carolina: Implications For Coastal Resource Policy, John All, Jenna Nelson
Remote Sensing Quantification Of Wetland Habitat Change In South Carolina: Implications For Coastal Resource Policy, John All, Jenna Nelson
The Geographical Bulletin
Increased urbanization of coastal areas has resulted in the pollution and destruction of wetland ecosystems worldwide. The effect of development on local wetland habitat was examined for Mount Pleasant, South Carolina, USA. Changes in the areal extent of wetlands in Mount Pleasant were determined through a quantification of changes in wetland margins from the 1970s to 1990s using Landsat data. The rate of wetland habitat loss accelerated from the 1980s to 1990s compared to the 1970s, even though coastal zone regulations had been strengthened and the rate of population increase was comparable for the decades selected for comparison. This paper …
Assessing A Small Summer Urban Heat Island In Rural South Central Pennsylvania, Danielle Doyle, Timothy W. Hawkins
Assessing A Small Summer Urban Heat Island In Rural South Central Pennsylvania, Danielle Doyle, Timothy W. Hawkins
The Geographical Bulletin
The development of cities potentially has a significant impact on climate. Buildings and infrastructure that replace natural vegetation often create new microclimates through changes in the energy balance associated with the built environment. The urban heat island effect, the phenomenon where air temperatures within an urban area are warmer than the surrounding rural areas, has been thoroughly examined for large urban areas. The purpose of this study is to determine the magnitude and extent of the urban heat island for a small urban area surrounded by agricultural land. Temperature data collected from several urban and rural locations over a four-month …

Biodiversity is essential for maintaining ecosystem balance and functionality, providing vital services such as climate regulation. The rapid decline in biodiversity, driven by habitat loss, habitat fragmentation, and climate change, poses significant threats to ecosystems. Climate change, in particular, is fundamentally altering habitats, leading to shifts in species distributions. However, existing research often lacks decomposed contribution analyses, particularly spatially, for a changing individual environmental attributes when modeling species distribution as an aggregate result of all factors and their interactions. Such analyses are crucial for identifying climate refugia and prioritizing conservation efforts. Taking endangered mammal species as an example, this study …
Statistical Downscaling Of Climate Datasets With Deep Generative Model And Bayesian Inference, Guiye Li, Guofeng Cao
Statistical Downscaling Of Climate Datasets With Deep Generative Model And Bayesian Inference, Guiye Li, Guofeng Cao
I-GUIDE Forum
Facing the challenges of global climate change, precise and high spatial resolution climate data are crucial and in pressing need for scientific research and analysis. However, most existing datasets are only available with very coarse spatial resolution and demand large-scale resolution enhancement. Meanwhile, climate datasets own much more intricate textures than natural images. Statistical downscaling or super-resolution (SR) with the deep-learning-based generative model might be a promising approach to address these challenges. It is worth noting that a learned Bayesian reconstruction with generative models (L-BRGM) method was proposed recently. The proposed Bayesian deep learning framework employs a single pre-trained generative …

Enhanced Lithological Mapping In Arid Crystalline Regions Using Explainable Ai And Multi-Spectral Remote Sensing Data, Hesham Morgan, Ali Elgendy, Amir Said, Mostafa Hashem, Wenzhao Li, Surendra Maharjan, Hesham El-Askary
Mathematics, Physics, and Computer Science Faculty Articles and Research
Lithological classification is essential for understanding the spatial distribution of rocks, especially in arid crystalline areas. Artificial intelligence (AI) recent advancements with multi-spectral satellite imagery have been utilized to enhance lithological mapping in these areas. Here we employed different AI models namely, Support Vector Machine (SVM), Random Forest Classification (RFC), Logistic Regression, XGBoost, and K-nearest neighbors (KNN) for lithological mapping. This was followed by the application of explainable AI (XAI) for lithological discrimination (LD) which is still not widely explored. Based on the highest accuracy and F1 score of the previously mentioned models, RFC model outperformed all of them, and …

Understanding Complex Socio-Environmental Systems With Spatial Agent-Based Models, Rebecca C. Vandewalle, Alexander Michels, Furqan Baig, Shaowen Wang
Understanding Complex Socio-Environmental Systems With Spatial Agent-Based Models, Rebecca C. Vandewalle, Alexander Michels, Furqan Baig, Shaowen Wang
I-GUIDE Forum
Our increasingly connected world is faced with complex socio-environmental problems (e.g., biodiversity loss, climate change, and food insecurity). Tackling these problems requires cross- disciplinary approaches that examine the problems based on synergistic spatial and system thinking. Spatial Agent-Based Models (SABMs) represent a powerful approach to understanding complex socio-environmental systems. However, research on SABMs and associated complex problem solving face grand challenges that must be overcome to effectively unleash the power of SABMs enabled by cyber-based geographic information science and systems (cyberGIS). This paper describes four such grand challenges —reproducibility, scalability, communication, and accessibility. Resolving these challenges will enable new spatial …
Communicating Uncertainty And Cataloging Bias In Spatial Data Science Education, Peter Kedron, Jiahua Chen
Communicating Uncertainty And Cataloging Bias In Spatial Data Science Education, Peter Kedron, Jiahua Chen
I-GUIDE Forum
Uncertainty is an unavoidable part of any spatial analysis, which makes quantifying and communicating uncertainty a requirement of any spatial data science study. However, current curricula leave students understanding the importance of uncertainty and concerned about potential bias, but without an actionable framework to improve their workflows or inferences. We propose a framework rooted in Bloom’s Taxonomy for introducing these concepts to spatial data science students.

Building Blocks For Geospatial Software Education Using The I-Guide Platform, Rebecca C. Vandewalle, Alexander Michels, Zhiyuan Li, Nattapon Jaroenchai, Shaowen Wang
I-GUIDE Forum
By combining advanced cyberinfrastructure with geospatial analysis capabilities and resources in an accessible online environment, the I-GUIDE Platform has great potential for geospatial computing focused education. However, learning occurs in different settings and contexts, both formal and informal. For I-GUIDE Platform to be successful, it should have the flexibility to support a variety of educational needs. In this paper, we argue for an expanded set of front-end building blocks to support diverse education and research use-cases, building on existing cyberGIS capabilities and Jupyter backend. We draw from experience working with the CyberGISX platform as an education tool in different learning …
Tradeoffs Of Generalization, Kyra M. Abrams, Peter T. Darch
Tradeoffs Of Generalization, Kyra M. Abrams, Peter T. Darch
I-GUIDE Forum
Models used in geospatial data science are often built and optimized for a specific local context, such as a particular location at a point in time. However, upon publication, these models may be generalized beyond this context, reused in research simulating or predicting other times and places. Without sufficient information or documentation, bias embedded in these models can in turn result in bias in the reuser’s research outputs. Drawing on a long-term qualitative case study of aging dams researchers and developers of models used by these researchers, we find significant documentation gaps. We combine a literature-based genealogy with interviews with …
Data-Intensive Convergence Science For Analyzing Place-Based Spatial Accessibility, Alexander C. Michels, Shaowen Wang
Data-Intensive Convergence Science For Analyzing Place-Based Spatial Accessibility, Alexander C. Michels, Shaowen Wang
I-GUIDE Forum
Place-based spatial accessibility is a critical tool for measuring the health, resilience, and sustainability of communities. Accessibility methods are employed by a wide range of fields to measure access to food, healthcare, infrastructure and other critical needs. While measures of access are relatively simple, they attempt to capture the complexities of human mobility and spatial decision-making to assess how well populations are served by the infrastructure, resources, and services at their disposal. This paper describes four key areas where data-intensive convergence science can revolutionize our understanding of place-based spatial accessibility by addressing issues of scale, spatial impedance, diversity, and accessibility. …

Spatial Patterns Of Methamphetamine In North Dakota, Alex Feidler, Roni Mayzer, Kevin Romig, Douglas Munski
The Geographical Bulletin
In the last decade, the methamphetamine situation has become critical in North Dakota, which has the third-highest rate of clandestine meth lab seizures in the country. This study addresses two questions: 1) What is the spatial pattern of meth–related arrests in North Dakota? and 2) What geographic factors account for the increased prevalence of meth use and production in the state? This study employs GIS overlay and multiple regression analysis to determine the spatiality of the phenomenon. The findings reveal that meth-related arrests tend to take place in the more urban southeast and central counties while meth lab seizures tend …
Displacement And Development: The Paradoxes Of India’S Tehri Dam, Jason Newton
Displacement And Development: The Paradoxes Of India’S Tehri Dam, Jason Newton
The Geographical Bulletin
The town of Old Tehri, India has been inundated by a lake created by the construction of the Tehri Hydroelectric Dam, one of the Indian government’s newest modernization and development projects. This dam is beset by a paradox: it attempts to bring modernization and development to the far reaches of the territory, while creating displacement conflicts which can change a relatively few people’s lives for the potential benefit of millions of others. A new city designed for the displaced residents, New Tehri, has been presented by the government as a solution for the displaced people. However, by conducting fieldwork onsite …
Growth-Liberating Technology Meets Fragmented Regulation: Decentralized Wastewater Systems In Wilson County, Tennessee, Kendrick J. Curtis
Growth-Liberating Technology Meets Fragmented Regulation: Decentralized Wastewater Systems In Wilson County, Tennessee, Kendrick J. Curtis
The Geographical Bulletin
Conventional sewage disposal technologies have long been a critical limiting factor of growth patterns. However, the advent of decentralized wastewater systems is weakening their influence. No longer constrained to areas where sewers can be economically extended or limited by the siting constraints of septic systems, developers are free to pursue projects wherever opportunities arise. In this paper, I examine what happened when this spatially liberating technology was introduced into an existing suite of regulations, jurisdictions, and actors involved in the development process. I found that while local governments are making rational decisions, they are doing so within limited spatial bounds. …
