Evolution Of Economic Geography’S Focus On Resource Studies: Historical Trajectory, Research Progress, And Emerging Trends, Yanxiang Fan, Canfei He

Bulletin of Chinese Academy of Sciences (Chinese Version)

Amid the intertwined contexts of global climate change, the reshaping of the geopolitical landscape, and China’s economic transformation, complex issues in the resource sector have increasingly come to the fore, highlighting the urgent need for systematic research from the perspective of economic geography. This study constructs an interactive analysis framework of core–extended dimensions to systematically review the developments and trends in resource research from an economic geography perspective. This study establishes a two-layer theoretical analysis framework of core and extended dimensions. The core dimension includes four aspects: resource elements in regional economic development, resource flows in global trade networks, resource …

Historical Redlining, Walkability, And Green Gentrification In Baltimore, Usa, Rafael B. De Andrade, Ella Baynes, Vanessa Belt, Joseph Colasacco, Camden Speilman

The Geographical Bulletin

Historical redlining created persistent patterns of racial segregation and spatial inequality in American cities. However, urban initiatives aimed at increasing green spaces in these neighborhoods increasingly trigger gentrification that can displace original residents. In this study, we examine the spatial intersection of 1930s-era Home Owners' Loan Corporation (HOLC) redlining boundaries, current property values, and multimodal park accessibility in Baltimore, Maryland. Using geographic data from 245 properties and 13 major parks, we developed an accessibility framework incorporating walking, public transit, and automobile travel modes to estimate accessibility to green spaces across neighborhoods with different redlining histories. Our spatial analysis reveals that …

Low-Income, Minority-Serving Public Schools In Southern California Have Disproportionately High Surface Temperatures, Joaquin Murillo, Gabriella R. Dauber, Joshua B. Fisher, Gregory R. Goldsmith

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Extensive evidence demonstrates that people from minority backgrounds often face unequal exposure to extreme heat and have less access to green space that can provide cooling relief. What is less clear is whether these inequities extend to students on school playgrounds, where high temperatures can affect physical health, social and emotional well-being, and learning. We paired high resolution, satellite remote sensing surface temperature data for all 615 of the public schools in Orange County, California (serving ca. 450,000 students) with data on neighborhood household income, race/ethnicity of school enrollment, distance from the coast, and Normalized Difference Vegetation Index as a …

Blue Space As Amenity And Disamenity: Disparity In Interstitial Water Bodies, Mara Pirone

Geography Honors Projects

Access to environmental amenities is distributed unevenly across urban areas, often due to discriminatory institutional practices such as redlining and racial covenants. Urban blue spaces (lakes, streams, rivers) can serve as either an environmental amenity or dis-amenity, depending on development and investment strategies. This paper explores how institutional racism, measured by variables such as historic redlining and racial covenant practices, shapes access to blue space as an amenity in the Twin Cities. Our results show that access to large, well-maintained, and well-invested blue space is distributed unevenly. Studying this relationship shows how cities continue to promote environmental injustice in interstitial …

Waterfront Ecologies: Coastal Resilience And Urbanization In Cali-Baja Region, Agniya Seliuzhytskaya

The study’s findings are intended to support policy development and planning initiatives that …

Green Extractivism And The Discursive Legitimization Of Deep-Sea Mining In The Clarion-Clipperton Zone, Kaitlyn Maritan

Theses and Dissertations

This thesis critically examines deep-sea mining as an example of green extractivism, constructed through narratives of responsible mining practices. A content analysis assesses the discursive tactics of four actors in the emerging industry; how they collectively legitimize deep-sea mining and manage the contradictions of sustainability and extractivism.

Unbroken Sovereignty: Land, Water, Education, And Nakoda And Oc̣Eti Ṡaḳowiŋ Tribes Of The Fort Peck Indian Reservation, 1850–1935, Richard Joseph Maska

History ETDs

This dissertation explores the intersection of sovereignty and development among the Nakoda (Assiniboine) and Oc̣eti Ṡaḳowiŋ (Sioux) Tribes of the Fort Peck Indian Reservation during the late nineteenth and early twentieth centuries. Methodologically, it draws on a critical reading of archival sources in conjunction with community input. It traces the emergence of reservation policy, government sponsored education, the imposition of allotment policy and private landownership, and the impact of state-sponsored irrigation and other development projects. I argue that the Tribes forged webs of affiliation and kinship to both assert their nationhood and navigate their involvement in such projects. These expressions …

Measuring And Mapping Spatial Distributions Of Soil Lead Concentrations Along Chicago Parkways: West Ridge And Near South Side, Alyssa M. Kain

DePaul Discoveries

Lead is a heavy metal that can be found in every part of our planet. Human activities like the extraction of fossil fuels and degradation of construction materials can release lead into the environment, where it travels and accumulates in places like our soil or water. Despite efforts to lower the use of lead-based materials within the last fifty years, lead contamination remains as a threat to public health and safety. Elevated blood lead levels are known to cause a variety of health issues particularly for young children and pregnant women. This study aims to measure, map, and analyze the …

Clearing The Air: Tracking Spatial And Temporal Pm2.5 Variability Along A Biking Transect In Chicago, Beau R. Rass

DePaul Discoveries

Fine particulate matter (PM₂.₅) poses significant risks to human health and disproportionately affects marginalized communities in urban environments (World Health Organization [WHO], 2021; Tessum et al., 2021). Using low-cost mobile sensors, this study explored spatiotemporal PM₂.₅ concentration patterns along a north–south transect of Halsted Street in Chicago. A 2B Technologies Portable Aerosol Monitor (PAM) mounted on a bicycle was used to continuously record PM₂.₅ concentrations with associated GPS coordinates at approximately two-second intervals during 16 sampling events between 08-12-2025 and 10-05-2025. PM₂.₅ concentrations did not differ significantly among the South Side, West Loop, and North Side regions, contrary to the …

Destination “Burning River”: Restoration And Placemaking In A Rust Belt City, Mia Compton-Engle

Geography Undergraduate Senior Theses

In 1969, the Cuyahoga River in Cleveland, Ohio caught fire from industrial pollution. Media narratives reframed the river fire as a symbol of environmental degradation, discursively transforming the Cuyahoga River from a place of industrial sacrifice to a place deserving ecological stewardship. Consequently, the river fire catalyzed the modern American environmental movement and local urban river restoration, materially transforming the Cuyahoga River from a place of industrial waste to a place of natural beauty and socioeconomic opportunity. Thus, urban river restoration presents an opportunity for novel placemaking: a local microcosm of the global turn towards urban sustainability. However, there is …

The Role Of Urban Forests In Mitigating Flooding Effects: A Case Study In Savannah, Georgia, Gillian Bush

Undergraduate Theses, Capstones, and Recitals

Flooding in coastal communities is shaped by the interaction between natural systems and urban development. Chatham County, a low-elevation region in the Savannah, Georgia metropolitan area along the eastern coast of the United States, is prone to coastal storms and frequently affected by flooding. It serves as a useful case study to better understand the factors behind flooding and the areas that are most at risk. This study uses GIS-based analysis to examine the overlap between flood risk, urban forest cover, and impervious surfaces. The results indicate elevated vulnerability along major transportation corridors and barrier islands, where high-risk flood zones …

Not Everyone Gets A Tree: Housing Values, Street Trees, And Equity In Portland, Matthew Moller

University Honors Theses

Street trees are positively associated with Portland home sale prices, but exposure and capitalization are uneven by race/ethnic neighborhood context. Urban trees are ecological assets, but their economic and equity implications remain uneven. This thesis examines street-tree exposure and 2023 residential sale prices in Portland, Oregon (n = 6,414) using a mixed-methodology hedonic design. Ordinary least squares models measure inventoried street-tree counts within 20m, 50m, and 100m buffers together with structural controls and census-block racial and ethnic context. Trees are positively and significantly associated with logged prices at all radii, with scale-sensitive magnitudes and modestly better fit as wider buffers. …

Urban Sacred Grove: A Visioning For Collective Care, Preservation, Environmental Justice, And Resilience, Oluwadara A. Ojugbele

Dissertations, Theses, and Capstone Projects

My capstone explores how the concept of sacred groves—a community-based practice of conserving forest areas for cultural, spiritual, or religious purposes—can be reimagined as a framework for urban environmental stewardship and community care. Sacred groves have historically varied across time and place but consistently serve as protected spaces that honor divine forces, ancestors, and community values. In the Yoruba context, groves demarcate lush forests as abodes for oriṣas (divine forces) and spiritual beings, often containing shrines and artifacts that embody cultural beliefs. My capstone draws on the sacred grove concept and aims to illustrate how urban communities might adopt sacred …

Perceptions Of Care: An Exploratory Case Study On Residents’ Perceptions Of Neighborhood And City Maintenance, Taylor Coats

Transforming Communities

Where one lives impacts both their physical and mental well-being. Though one’s builtenvironment is an important factor, the perception of one’s environment influences mental well-being. This qualitative study examines what influences residents’ perceptions of theirneighborhood and local governmental efforts to maintain and improve their community. Thisstudy utilized a case study methodology to interview residents, stakeholders, and politicians intwo neighborhoods in a mid-sized urban city in the Midwest (N = 16). This study identified threecore aspects that influence participants' perceptions of their neighborhoods and city efforts tomaintain and improve their community: 1) history with the city; 2) geographic location withinsegregated neighborhoods; …

The Queer Family Farm: Exploring Agrifood Justice And Management Philosophies Among Lgbtq+ And Family Farmers In Minnesota And Wisconsin, Julia I. Castellano

Geography Honors Projects

Agriculture in the US countryside has long been idolized as a symbol of traditional American values via the “family farm” while queerness has become associated with avant-gardism and urbanity. This study contributes to the nascent but growing scholarship at the convergence of these seemingly opposing propositions: queer farming. Specifically, I contextualize LGBTQ+ farmers in Minnesota and Wisconsin through historical and modern perspectives on the dominant heteronuclear family farm and industrial agricultural landscape to understand how they approach farming in the absence of traditional gender roles and as predominantly small, alternative farmers. The family farm as we imagine it today is …

Public Pool Usage As Adaptation Against Urban Heat, Stefan Borsky, Eric Fesselmeyer

Research Collection College of Integrative Studies

This paper examines the relationship between urban heat and outdoor public pool usage. Using attendance data from all 53 outdoor public pools in New York City, we analyze nonlinear effects of heat on pool usage across socioeconomic contexts. Pool attendance rises sharply with heat, especially in low-income neighborhoods where alternative coping options are likely limited. We also find that public pools reduce heat-related emergency medical service calls. Our findings highlight the need for equitable investment in blue infrastructure to enhance urban climate resilience and demonstrate how this type of adaptive infrastructure can play a critical role in managing urban heat.

An Assessment Of Historical Planning Processes And Greenspace Distribution (1975–2024): A Case Study Of Portland, Oregon, Usa, Quadri Olatunbosun Taiwo, Vivek Shandas, Damilola Emmanuel Oluyege

Geography Faculty Publications and Presentations

The Portland study examined past planning regulations and greenspace distribution over the period of fifty years, with particular attention given to neighborhood differences between invested and non-invested neighborhoods. This exploratory study examined spatial greenspace using Normalized Difference Vegetation Index (NDVI) imagery. We tested the study hypothesis using the GIS Ordinary Least Squares (OLS) regression test to predict how key sociodemographic characteristics affect the provision of greenspace in non-white disinvested neighborhoods. The key findings suggested a consistent pattern of greenspace inequality, heavily shaped by historically disadvantaged ethnic status. Areas with higher non-white populations may have significant less greenspace (p < 0.001). Although median household income had a minimal negative impact, educational attainment showed a slight positive correlation. We employed multidisciplinary theoretical frameworks such as historical institutionalism, urban political ecology, and environmental justice. The study illustrated how historical decisions may have established path dependencies that are currently perpetuating greenspace inequalities. Policy solutions advocate for integrating restorative justice principles and rigid enforcement of 3-30-300 greenspace equity legislation to offset these long-term disparities.

Ecomusicological Representation Of Climate Change And Environmental Sustainability In Selected Bongo Fleva Lyrics In Tanzania, Auson N. Wincheslaus

Journal of Humanities and Social Sciences

This article critically explores how Bongo Fleva’s lyrics engage with environmental themes; and the interrelationship between nature and culture in the context of the Anthropocene. The data were purposively sampled from YouTube via content analysis, from which 50 Bongo Fleva songs were listened to, and only 10 environmentally-themed songs were analysed. Then, the selected songs were subjected to transcription (from oral to written form), translation (from Kiswahili into English), and close reading and textual analysis. The close reading of the selected songs focused on the employed aesthetic and rhetorical strategies, such as anthropomorphism, symbolism, antithesis, apocalyptic tones, solastalgia, rhetorical questions, …

Satellites, Urban Heat, And Environmental Justice: Community As The Bridge Between Analysis And Action, Joshua B. Fisher, Ambar Rivera, Ava Cison, Ashley Agatep, Kainani Tacazon, Sophia Spiegleman, Alison Mckenery, Rio E. Fisher, Reginald Archer, Jason A. Douglas

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Heat waves are increasing in frequency, intensity, magnitude, and duration, causing a disproportionate impact on marginalized communities exposed to urban heat islands. Newly emerging spaceborne thermal sensing instruments, such as ECOSTRESS and Hydrosat, now have the capabilities to measure urban surface temperatures accurately at the block level (< 100 m) and with enough frequency to capture transient heat waves (daily to subweekly). Such data are critical for monitoring and informing policy and mitigation efforts, such as resurfacing, green space, cooling stations, and medical mobilization. These serve to advance environmental justice and reduce health risks—and deaths—among the most vulnerable: minority, low-income, elderly, those with physical- and mental-health preconditions, unhoused, children, and outdoor workers. While scientists have increasingly used satellite data to quantify urban heat islands and risks to communities, there remains a significant gap in action resulting from such analyses—a figurative and literal “valley of death.” Reviewing over 500 scientific publications, we identify a critical lack of engagement with the communities being analyzed (10.9%; n = 58); yet, community engagement is key to bridging such analysis with subsequent action. Here, we demonstrate how participatory community engagement directly with data and analysis leads to increased policy changes and mitigation efforts. Our framework has immediate implications for how scientists may augment their work and thought processes to achieve …

"We're Going To Tear Up The Caldera So We Can Have An Electric Car": Wrestling With Prospective Lithium Mining In The Oregon Desert, Elizabeth Bartholomew, Alida Cantor, Kate Berry, Noel Vineyard

Geography Faculty Publications and Presentations

Extraction of lithium, a key ingredient for renewable energy transitions, is a land- and water-intensive process. In this study, we use qualitative, place-based research to explore socio-environmental imaginaries surrounding a landscape on the verge of change due to lithium mining. We examine the ways that different actors are wrestling with the costs, benefits, and uncertainties of potential open-pit lithium mining in Oregon’s section of the McDermitt Caldera. In contrast to previous research which has described support for mining amongst those closest to the mine site, we find that in this case, perceptions of mining are characterized by ambivalence, uncertainty, and …
