Prediction Of Traffic Congestion Using A Time-Series Model And Spatiotemporal Data: A Case Study Of The Atlanta Downtown Connector, Yunsik Kim

The Geographical Bulletin

Traffic congestion poses significant socio-economic challenges, and many urban commuters experience time and cost burdens due to traffic jams. Effectively managing and predicting traffic congestion is crucial for contemporary urban planning and operations. This study aims to predict congestion using time-series deep learning models, focusing on a chronically congested road section. The research area is the Atlanta Downtown Connector, a heavily trafficked route passing through the heart of the city of Atlanta. To address issues often associated with sensor and GPS-based data collection, traffic data was obtained from an open-source online map service, Google Maps. A multivariate time-lagged LSTM model …

A Remote Sensing Investigation Of The 2022 Invasion Of Eastern Ukraine On Agricultural Landcover, Michael S. Agbozo, Luke J. Marzen, Chandana Mitra

The Geographical Bulletin

Ukraine-Russian political relations over the years have alternatively experienced periods of tranquility and turmoil with violent conflicts since 1917, including the events of the 2014 annexation of Crimea and the 2022 Russian invasion of the entirety of Ukraine. These conflicts remain developmental threats and their assessment requires multi-perspective analysis. Understanding the spatial dimensions of such conflicts and their consequences on physical and social spaces at varying scales could provide credible scientific impetuses on which targeted post-conflict remediations could be built. This preliminary study therefore takes advantage of the capabilities of satellite remote sensing, to provide quick and effective spatiotemporal analysis …

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 …

Evaluating The Use Of Unpiloted Aerial Systems To Detect And Monitor Beech Bark Disease In New England Forests, Isabelle Lopez, Benjamin T. Fraser, Russell G. Congalton

The Geographical Bulletin

The American beech (Fagus grandifolia) plays a key role throughout eastern North American forests. However, beech bark disease (BBD) causes widespread mortality of beech trees. We investigated whether imagery collected using an unpiloted aerial system (UAS) could differentiate beech tree health. Reference data were collected from 140 beech trees in New Hampshire and were visually classified as having “no/trace damage,” “moderate damage,” or “heavy damage.” Multispectral imagery was collected from a UAS, and 44 image features were derived for each beech crown. We used machine learning to identify the importance of each feature in distinguishing between the three health classes …

High-Mountain Hazards In The Indian Himalaya: An Assessment Of The Causes And Effects Of The Chamoli Flood In 2021, Christina M. Salzmann, Sarah J. Halvorson, Anna E. Klene

The Geographical Bulletin

On 7 February 2021, a devastating flood severely impacted the Ronti Gad, Rishiganga, and Dhauliganga River Valleys in the northwestern District of Chamoli, India. The flood washed away two hydropower projects and caused more than 200 fatalities. This study assessed some of the causes and effects of this catastrophic flood event and aims to provide further documentation that the event was not caused by a glacial lake outburst flood, as many reports initially indicated. Analysis of high-resolution satellite imagery, digital elevation model (DEM) differencing, and precipitation and temperature data showed that an ice-rock avalanche was released as a result of …

The Meteorology And Impacts Of The September 2020 Western United States Extreme Weather Event, Emma N. Russell, Paul Loikith, Idowu Ajibade, James Done, Chris Lower

Geography Faculty Publications and Presentations

In September 2020, Western North America was impacted by a highly anomalous meteorological event. Over the Pacific Northwest, strong and dry easterly winds exceeded historically observed values for the time of year and contributed to the rapid spread of several large wildfires. Nine lives were lost and over 5000 homes and businesses were destroyed in Oregon. The smoke from the fires enveloped the region for nearly two weeks after the event. Concurrently, the same weather system brought record-breaking cold, dramatic 24-h temperature falls, and early-season snowfall to parts of the Rocky Mountains. Here we use synoptic analysis and air parcel …

Patterns Of Infringement, Risk, And Impact Driven By Coal Mining Permits In Indonesia, Tim T. Werner, Tessa Toumbourou, Victor Maus, Martin C. Lukas, Laura J. Sonter, Muhamad Muhdar, Rebecca K. Runting, Anthony J. Bebbington

Geography

Coal mining is known for its contributions to climate change, but its impacts on the environment and human lives near mine sites are less widely recognised. This study integrates remote sensing, GIS, stakeholder interviews and extensive review of provincial data and documents to identify patterns of infringement, risk and impact driven by coal mining expansion across East Kalimantan, Indonesia. Specifically, we map and analyse patterns of mining concessions, land clearing, water cover, human settlement, and safety risks, and link them with mining governance and regulatory infractions related to coal mining permits. We show that excessive, improper permit granting and insufficient …

Learning From Their Flocks: Analyses Of Power On Hudson River Valley Livestock Farms, Mark D. D'Alessandro

Dissertations, Theses, and Capstone Projects

Livestock farming in the Hudson River Valley, and selling meat in New York City farmers’ markets, are activities bounded by a region, and heavily influenced by place. Farming is represented in this project as a material linkage between urban and rural, both shaped by power relations, and the respective places of production and consumption. Interrupted by the COVID-19 pandemic, this study investigates placemaking and power dynamics on farms, their marketplaces, and spaces in between, during normal market conditions, and those which are anything but normal. The findings expose the reader to the representations of place in a local, niche market, …

Containerization Of Seafarers In The International Shipping Industry: Contemporary Seamanship, Maritime Social Infrastructures, And Mobility Politics Of Global Logistics, Liang Wu

Dissertations, Theses, and Capstone Projects

This dissertation discusses the mobility politics of container shipping and argues that technological development, political-economic order, and social infrastructure co-produce one another. Containerization, the use of standardized containers to carry cargo across modes of transportation that is said to have revolutionized and globalized international trade since the late 1950s, has served to expand and extend the power of international coalitions of states and corporations to control the movements of commodities (shipments) and labor (seafarers). The advent and development of containerization was driven by a sociotechnical imaginary and international social contract of seamless shipping and cargo flows. In practice, this liberal, …

Staying Power: The Struggle For Space And Place In Crown Heights, Brooklyn, Erin E. Lilli

Dissertations, Theses, and Capstone Projects

This dissertation looks at how gentrification touches down, at the neighborhood and individual scale, in Crown Heights and reproduces experiences of racial inequality in home and place. Taking an historical materialist approach and drawing on residential oral histories, this study frames these reproductions of racial inequality as always-in-tension with ongoing acts of resistance from Black homeowners, renters, and long-term residents. Specifically, the research explores the conditions under which Black residents of a predominantly Afro-Caribbean neighborhood acquire and maintain—and in some cases lose—their housing and sense of place and belonging. These residents resist the varied tactics of anti-Blackness such as landlord …

Low Elevation Coastal Zone (Lecz) Population Social Vulnerability And Risk: A Spatial Analysis Based On The 2015-16 National Family Health Survey (Nfhs-4) Of India, Paradorn Wongchanapai

Dissertations, Theses, and Capstone Projects

Background & Problem Statement:

This study assessed social vulnerability and risk to hydroclimate hazards of Indian urban and rural populations in the Low Elevation Coastal Zone (LECZ), a contiguous coastal area with elevations less than 10 meters. The LECZ is considered an at-risk area as hydroclimate hazards tend to be heightened. Moreover, being the most populous country in the world, any hydroclimate hazards that hit the LECZ would disproportionately impact a large number of Indian populations. Understanding the social vulnerability and risk of the LECZ populations can help mitigate and prevent potential adverse outcomes for the populations.

Importantly, this study …

Dissertations, Theses, and Capstone Projects

The ecological impacts of changes to land use are relevant to concerns about climate change, eutrophication of waterbodies, and reductions in biodiversity. As a foundational component of ecosystem functioning, changes to soil biogeochemistry have significant effects on overall ecosystem health. With cities continuing to grow and develop in extent, the impacts of urbanization and suburbanization on soils are of particular concern. Despite a wide range of natural climatic and geologic conditions, several factors have driven similar patterns of land transformation and management across the United States. In particular, federal initiatives including the Home Owners Loan Corporation, the Federal Housing Administration, …

Interviews And Perspectives Among Community Members Working With Undocumented Female Border Crossers In The States Along The United States-Mexico Border, Melissa M. Frasco

Dissertations, Theses, and Capstone Projects

In order to discuss immigration in the context of the United States, we must dispel the myth that immigration is monolithic. Therefore, when we discuss national identity, gender equality, policy, employment rates, and countless other ordinary topics, we are discussing immigration, as it is embedded in our history and our future. The goal of my research is to delineate the experiences of violence that female border crossers undergo in the process of crossing into the United States via the southernmost border. The data collection process involved four semi-structured interviews to collect oral histories from workers at community-based organizations. These organizations …

Tragedi Kebudayaan Dan Objektivasi Hubungan Manusia: Sebuah Refleksi Mengenai Pemikiran Georg Simmel, Kevin Nobel Kurniawan

Masyarakat: Jurnal Sosiologi

This article attempts to describe Simmel’s intellectual thoughts, particularly those related to the mode of human relationship. By applying a systematic literature review, this article demonstrates the uniqueness of Simmelian thought in comparison to other major classical sociological thinkers, like Emile Durkheim, Karl Marx, and Max Weber. For Simmel, a macro-level analysis on societal culture can be carried out by focusing on the micro dimension of the everyday life. In this context, Simmel speaks of the tragedy of culture that transpires through the process of objectification, where relationships become increasingly impersonal. At the end, this article provides a commentary on …

Digital Echoes: The Influence Of Internet And Social Media On The “Ideal” Conception Of Motherhood In Indonesian Stunting Programs, Sari Damar Ratri

Morphodynamic Diversity Of Alluvial River Systems In The Upper Yellow River Watershed, Qinghai-Tibet Plateau, Xiwei Guo

Dissertations - ALL

Alluvial rivers exhibit diverse forms and dynamic processes based on the physiographic configuration and in response to the interactions between water flow, sediment transport, and channel morphology. The current understanding of the formative and evolutionary processes controlling channel morphology and the dynamics remains incomplete, as it falls short of explaining and predicting a variety of channel forms and processes. Using data derived from remote sensing analysis and field measurement, this dissertation investigates the morphological characteristics, lateral adjustment, and channel-floodplain interactions of meandering and anabranching rivers in a pristine, high-altitude environment in the source watershed of the Yellow River, eastern Qinghai-Tibet …

Containment: Logistics, Environmental Conflict, And The Legal Geography Of Inland Ports, Jared Charles Whear

Dissertations - ALL

In 2020, as the COVID-19 pandemic disrupted the supply chain, people worldwide received a crash course in the importance of logistics when corporations like Amazon became a lifeline for many. Before this increased public attention, however, scholars in geography had shown logistics to be a highly political yet indispensable process in the operation of global capitalism. Much of this scholarship underscores how the logistics industry frequently operates at the expense of marginalized people, workers, and the environment. In this dissertation, I expand on this work by adding a legal geography and political ecology analysis—a legal political ecology approach—to examine the …
