Development And Disparity In Glasgow: The Desirability Of Urban Water Proximity, Brian Morgan

Theses and Dissertations

This study was conducted to examine the possibility that a spatial relationship exists between demographic trends considered to be indicative of gentrification, and ongoing regenerative activity taking place along an urban canal and the adjacent neighborhoods in a northern section of Glasgow, Scotland. Rates of demographic change between the 2001 and 2011 Scottish Census results for the study area were contrasted with the same variables citywide, using the census Output Area (OA) as the aggregate unit. Results were combined to produce an index of gentrification. Positive results towards gentrification were identified in many of the OAs for a significant number …

Geographic Trends Of Terrorist Attacks And Active Shooter Scenarios Perpetrated Inside U.S. Military Installations And Facilities, 1970-2019, Aaron James Ebbenga

All Graduate Theses, Dissertations, and Other Capstone Projects

In recent years, a variety of devastating terrorist attacks have been perpetrated against American military installations, spurring not only national outrage but also global public upheaval. Our public preconception of considering military bases as impenetrable to the dangers of active shooter scenarios and bomb threats has since become widely scrutinized by worldwide media sources. For this reason, the people of the U.S. have expressed concerns about the safety of the nation’s military personnel. The diverse nature of the attacks, committed both by domestic and foreign terrorist organizations, illustrates vulnerabilities of American military installations and support facilities. These types of attacks …

[In lieu of an abstract, the synopsis is presented] Nor Any Drop to Drink: Flint’s Water Crisis (2018) is a 124-minute-long documentary directed by Dr Cedric Taylor, a sociologist with expertise in environmental justice and racial health disparities, with cinematography by Daniel Bracken. Nor Any Drop to Drink examines the causes of the Flint water crisis and documents the crisis’s impacts on city residents years after the initial water contamination. The first half of the film analyses the political roots of the water crisis: the imposition of emergency management in Flint, a system of undemocratic rule in which the governor …

The Politics Of Owing: Accounting, Water Disconnection, And Austerity Urbanism In Detroit, Melissa Heil

Faculty Publications - Geography, Geology, and the Environment

With the rise of austerity urbanism, contemporary urban governance has been described as “rule by accountancy.” Yet the intricacies of accounting practice have been underexplored in the austerity urbanism literature. Drawing on insights from critical accounting studies, I interrogate accounting practices as political exercises that draw people and institutions into ties of obligation (accountability), shape social relations, and structure the conditions of urban life. Through this lens, practices of accounting can be understood not just as a technocratic tool of the financialized state, but as a contested terrain of urban political struggle. Examining the case of austerity-driven water service disconnections …

Bloodshed, Baptism, Beer: Racial Capitalism And Settler Colonialism On The Medieval Baltic, Nicholas Salvato

Geography Honors Projects

Scholarly and popular usage of the term “racial capitalism” has increased exponentially over the past decade, but the validity and implications of its use remain hotly contested. The late Cedric Robinson is the undisputed popularizer of this phrase and is referenced widely by both the slogan’s detractors and proponents. Despite this, little work has been done to engage with the core of his argument about racial capitalism: that capitalism is inalienably racial due to the racialism of the medieval European societies that spawned it. Debates over Robinson’s ideas have thus disregarded the substance of his deployment of the phrase and …

Perspectives On New Wilderness Area Designations In Michigan's Upper Peninsula, Olivia Joy D. Ghormley

Dissertations, Master's Theses and Master's Reports

The Wilderness Act of 1964 designated certain areas denoted as wilderness in the United States of America for the sake of preservation and conservation. In the state of Michigan, 16 designated wilderness areas currently exist, and the Environmental Law and Policy Center (ELPC) is advocating for the addition of four new wilderness designations. The addition of these areas would add about 51,000 acres of federally recognized wilderness areas to the Upper Peninsula of Michigan. This paper aims to understand public attitudes and political support or opposition to these new wilderness designations among residents and visitors of the Upper Peninsula of …

Arctic Greening: Characterizing Tundra Vegetation From In-Situ And Remotely Sensed Observations, Shira Ann Ellenson

Graduate Student Theses, Dissertations, & Professional Papers

As the Arctic has warmed at twice the rate of the global average, vegetation productivity has also been increasing. While satellite remote sensing is useful for summarizing Arctic-wide trends, changes in tundra species heights, densities, composition, and distribution can be missed at coarse resolution. Smaller, plot-scale studies are necessary to better understand vegetation dynamics at fine scales occurring on the ground.

In 1995, high-resolution traditional aerial photographs and in-situ measurements of vegetation characteristics were taken at a series of plots established on the Alaskan North Slope. Repeat field surveys in 2021 revealed increases in plant cover for deciduous shrubs and …

A Process-Model Perspective On Recent Changes In The Carbon Cycle Of North America, Guillermo Murray-Tortarolo, Benjamin Poulter, Rodrigo Vargas, Daniel Hayes, Anna M. Michalak, Christopher A.

Geography

Continental North America has been found to be a carbon (C) sink over recent decades by multiple studies employing a variety of estimation approaches. However, several key questions and uncertainties remain with these assessments. Here we used results from an ensemble of 19 state-of-the-art dynamic global vegetation models from the TRENDYv9 project to improve these estimates and study the drivers of its interannual variability. Our results show that North America has been a C sink with a magnitude of 0.37 ± 0.38 (mean and one standard deviation) PgC year−1 for the period 2000–2019 (0.31 and 0.44 PgC year−1 in each …

Chinese Neoglobalization In East Africa: Logics, Couplings And Impacts, Pádraig R. Carmody, James T. Murphy

Geography

The most significant case of transnational state capitalism today is China's Belt and Road Initiative (BRI) which seeks to expand/extend the country's geoeconomic and geopolitical integrations globally. We conceptualise the BRI as manifest principally through industrial offshoring, infrastructure investments and exports from China. These vectors articulate with particular places, forming transnational couplings that shape development outcomes. We examine the BRI's couplings and their development implications in the East African countries of Djibouti, Ethiopia and Kenya where China has engaged significantly. We demonstrate the contingent manner of BRI's variegations; its pragmatism, flexibility, and limitations as a hegemonic or developmental project.

Linking Tree Cover Change To Historical Management Practices In Urban Parks, Sabine Nix, Lara A. Roman, Marc Healy, John Rogan, Hamil Pearsall

Geography

Context: Urban tree canopy (UTC) in parks is shaped by complex interactions between social and ecological processes over decades. To understand UTC change in parks, it is critical to identify and characterize the unique set of social processes that drive long-term change. Objectives: We sought to uncover the feedbacks between social processes and long-term UTC changes in parks of a post-industrial city that experienced substantial population loss and park disinvestment. Methods: Our mixed-methods approach involved quantifying spatiotemporal UTC changes and connecting those changes to historical management practices for three parks in Philadelphia, PA (US). We delineated UTC using aerial imagery …

What Makes Wildfires Destructive In California?, Alexandra D. Syphard, Jon E. Keeley, Mike Gough, Mitchell Lazarz, John Rogan

Geography

As human impacts from wildfires mount, there is a pressing need to understand why structures are lost in destructive fires. Despite growing research on factors contributing to structure loss, fewer studies have focused on why some fires are destructive and others are not. We characterized overall differences between fires that resulted in structure loss (“destructive fires”) and those that did not (“non-destructive wildfires”) across three California regions. Then, we performed statistical analyses on large fires only (≥100 ha) to distinguish the primary differences between large destructive large fires and large non-destructive fires. Overall, destructive fires were at least an order …

Applying Landscape Fragmentation Analysis To Icescape Environments: Potential Impacts For The Pacific Walrus (Odobenus Rosmarus Divergens), Anthony Himmelberger, K E. Frey, Florencia Sangermano

Geography

Sea-ice cover across the Arctic has declined rapidly over the past several decades owing to amplified climate warming. The Pacific walrus (Odobenus rosmarus divergens) relies on sea-ice floes in the St. Lawrence Island (SLI) and Wainwright regions of the Bering and Chukchi seas surrounding Alaska as a platform for rest, feeding and reproduction. Lower concentrations of thick ice floes are generally associated with earlier seasonal fragmentation and shorter annual persistence of sea-ice cover, potentially affecting the life history of the Pacific walrus. In this study, 24 Landsat satellite images were classified into thick ice, thin ice or open water to …

Probabilistic Tracking Of Annual Cropland Changes Over Large, Complex Agricultural Landscapes Using Google Earth Engine, Sitian Xiong, Priscilla Baltezar, Morgan A. Crowley, Michael Cecil, Stefano C. Crema, Eli Baldwin, Jeffrey A. Cardille, Lyndon Estes

Geography

Cropland expansion is expected to increase across sub-Saharan African (SSA) countries in the next thirty years to meet growing food needs across the continent. These land transformations will have cascading social and ecological impacts that can be monitored using novel Earth observation techniques that produce datasets complementary to national cropland surveys. In this study, we present a flexible Bayesian data synthesis workflow on Google Earth Engine (GEE) that can be used to fuse optical and synthetic aperture radar data and demonstrate its ability to track agricultural change at national scales. We adapted the previously developed Bayesian Updating of Land Cover …

New Political Ecologies Of Renewable Energy, Sarah Knuth, Ingrid Behrsin, Anthony Levenda, James Mccarthy

Geography

The critique of fossil fuel regimes has been a foundational concern for the field of political ecology, in its drives to expose the injustices and harms of energy extractivism and its early warnings of the climate crisis. However, it is increasingly evident that renewable energy sources and their infrastructures will carry their own costs and trade-offs, and that critique, resistance and alternative movement-building are needed to forge a truly just renewable energy transition. This theme issue underlines the many ways in which political ecology is well-positioned to lead critical and engaged scholarship in support of energy/climate justice. In this introduction …

Emerging Hot Spot Analysis To Indicate Forest Conservation Priorities And Efficacy On Regional To Continental Scales: A Study Of Forest Change In Selva Maya 2000-2020, Nicholas Cuba, Laura A. 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 …

Albedo Changes Caused By Future Urbanization Contribute To Global Warming, Zutao Ouyang, Pietro Sciusco, Tong Jiao, Sarah Feron, Cheyenne Lei, Fei Li, Ranjeet John, Peilei Fan, Xia Li, Christopher A. Williams, Guangzhao Chen, Chenghao Wang, Jiquan Chen

Geography

The replacement of natural lands with urban structures has multiple environmental consequences, yet little is known about the magnitude and extent of albedo-induced warming contributions from urbanization at the global scale in the past and future. Here, we apply an empirical approach to quantify the climate effects of past urbanization and future urbanization projected under different shared socioeconomic pathways (SSPs). We find an albedo-induced warming effect of urbanization for both the past and the projected futures under three illustrative scenarios. The albedo decease from urbanization in 2018 relative to 2001 has yielded a 100-year average annual global warming of 0.00014 …

A Modified Vegetation Photosynthesis And Respiration Model (Vprm) For The Eastern Usa And Canada, Evaluated With Comparison To Atmospheric Observations And Other Biospheric Models, Sharon M. Gourdji, Anna Karion, Israel Lopez-Coto, Subhomoy Ghosh, Kimberly L. Mueller, Yu Zhou, Christopher A. Williams, Ian T. Baker, Katharine D. Haynes, James R. Whetstone

Geography

Atmospheric CO2 measurements from a dense surface network can help to evaluate terrestrial biosphere model (TBM) simulations of Net Ecosystem Exchange (NEE) with two key benefits. First, gridded CO2 flux estimates can be evaluated over regional scales, not possible using flux tower observations at discrete locations for model evaluation. Second, TBM ability to explain atmospheric CO2 fluctuations due to the biosphere can be directly tested, an important objective for anthropogenic emissions monitoring using atmospheric observations. Here, we customize the Vegetation Photosynthesis and Respiration Model (VPRM) for an eastern North American domain with strong biological activity upwind of urban areas. Parameters …

Political Culture: An Unexplored Factor In Climate Change Diplomacy, Alexander Suen

Theses and Dissertations (Comprehensive)

As climate change continues to ravage the world, mitigation efforts continue to be insufficient to rise to the challenge. Inaction on climate change has been traditionally explained by economic incentives, but some of the variability in climate policies cannot be explained by economics alone. Some variations could be accounted for by the deeply rooted national political culture of Anglo-settler colonies. This political culture may inhibit the willingness of such states to cooperate on climate change. In this dissertation, I describe the political philosophy of the Anglo-settler colony, and the histories of domination of its white settlers over the indigenous peoples …

"Ethnic" Some Days, White The Rest: Whittier, Ca As A Case Study In Mexican-American Racialization And Assimilation In Los Angeles County, Maria Gutierrez-Vera

CMC Senior Theses

Per the U.S. Census Bureau, the Latino population in the United States stands at 60.5 million. This thesis tells the story of a few hundred-thousand Mexican-Americans in Southeast Los Angeles County’s suburbs, who live in a region nicknamed the “Mexican Beverly Hills.” This is a unique site of middle-class ethnic affluence, but also a place where questions of “Hispanic” racial identity, assimilation, and belonging are played out. The Mexican Beverly Hills promises residents the fulfillment of their own (Mexican-) American Dream, but also plays into tropes of model minorities, demands assimilation and ethnic betrayal from its residents, and is the …
