“Turn The Faucet”: Right-Wing Hydrosocial Imaginaries Of Irrigation Water In The Western United States, Alexander Reid Ross, Thien-Kim Bui, Alida Cantor

Geography Faculty Publications and Presentations

The second administration of United States President Donald Trump has taken an authoritarian, centralized approach to governance in the United States. Water management is one area in which the president has attempted to show dominance. This research theorizes President Trump’s concept of water in the United States West as a “hydrosocial imaginary” in which the release of water from rivers and reservoirs indicates virility, action, and power, instead of liberal cautiousness and prudence. By ordering the release of two billion gallons of water from California’s Central Valley into the dry Tulare Basin one hundred miles north of Los Angeles for …

Situs Lida Ajer Dalam Konteks Supererupsi Erupsi Toba, Zulianikha S. Putri, Arni Nazirawati, Alia Fatima

Multikultura

The Toba eruption approximately 74,000 years ago was one of the largest volcanic events of the Quaternary and is often associated with the catastrophic hypothesis, which argues that the event caused extreme global cooling and severe reductions in human populations. However, recent studies suggest that its impacts were less destructive than previously assumed. This paper examines the position of Lida Ajer Cave within the context of the Toba eruption through a literature review of archaeological, geological, and paleoenvironmental publications. The review shows that the presence of Homo sapiens at Lida Ajer, dated to approximately 73,000–63,000 years ago, places the site …

Cramer’S V-Based Driver Screening For Land-Use Change Prediction In A Flood-Prone Coastal Lowland Of Demak Regency, Indonesia (2002-2035), Mellinia Regina Heni Prastiwi, Sigit Heru Murti Budi Santosa, Sudaryatno Sudaryatno, Daud Richard Malusu

Jurnal Pendidikan Geografi: Kajian, Teori, dan Praktek dalam Bidang Pendidikan dan Ilmu Geografi

Land use in the floodplain of Demak Regency has changed rapidly under pressure from urbanization and economic activity, and this change is hypothesized to contribute to increased flood risk, a concern reinforced by the extreme flood disaster of February-March 2024, although establishing a direct causal link between the observed land-use trajectory and the magnitude of that specific flood event would require dedicated hydrological modeling beyond the scope of this study. This study proposes examining the spatio-temporal dynamics of land use from 2002 to 2024 and forecast the conditions in 2035 utilizing a Land Change Model (LCM) framework combining Markov chains …

Assessing Coastal Vulnerability To Extreme Waves And Abrasion In Bandar Lampung City: Implications For Spatial Pattern And Infrastructure Adaptation, Adnin Musadri Asbi, Yudha Rahman, Fachri Muhammad Rasyid, Diyanti Isnani Siregar

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

Coastal cities in Southeast Asia face dual challenges of rapid urbanization and increasing climate pressures, demanding robust integration of risk assessment into spatial planning. This study assesses the vulnerability of Bandar Lampung City's coastal area to extreme waves and abrasion, analyzing implications for its spatial plan. Using a standard hazard index and a spatial overlay against the city's Regional Spatial Plan (RTRW), the research identifies a 'Medium' hazard classification across all four studied sub-districts. Crucially, this classification is not driven by significant hydrodynamic forces but is substantially amplified by anthropogenic vulnerabilities. A development-centric spatial policy has led to the dominance …

Democratic Economic Planning From And For Social Reproduction: Foundations For A Postcapitalist Research Agenda, Sophie Elias-Pinsonnault, Bengi Akbulut, Audrey Laurin-Lamothe

Emancipations: A Journal of Critical Social Analysis

As ecological and social crises render the transformation of capitalist economic organization increasingly urgent, the resurgence of interest in democratic economic planning confronts a foundational blind spot: the systematic neglect of social reproduction. This paper argues that any genuinely needs-based planned economy must extend its scope beyond formally recognized productive activities to encompass the full spectrum of reproductive labor through which human and non-human life is sustained and regenerated. Drawing on feminist political economy and the Marxist-feminist tradition, the authors argue that meeting needs requires more than reorganizing production: it demands confronting the question of who does reproductive work, at …

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 …

The Palm Farm Next-Door: Land Concessions, Livelihoods, And Nutrition In Plantation-Adjacent Communities, Julia Entwistle

Electronic Theses and Dissertations

Large-scale land concessions have reshaped agrarian landscapes globally, yet their implications for community land tenure, livelihoods, and nutrition remain unevenly understood. This dissertation examines how plantation agriculture and foreign investment have transformed land access, labor relations, and food systems in Liberia, a country with one of the highest proportions of land under concession globally. Guided by a political ecology framework, the study employs a mixed-methods design integrating policy analysis, in-depth interviews, and household surveys across two palm oil concession sites. The findings show that ambiguous land policies historically facilitated dispossession, while recent legal reforms have enabled communities to strategically mobilize …

Publications and Research

The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on the Caspian Sea remain poorly understood. Here, we integrate satellite observations, in situ hydrological records and reanalysis data to examine recent drivers of the Caspian water loss. We show that total river inflow to the Caspian Sea has declined significantly, primarily due to reduced discharge from the Volga River. At the same time, precipitation over the basin has remained broadly stable, while …

Research Collection College of Integrative Studies

As countries aim to reduce resource consumption and greenhouse gas (GHG) emissions, Whole Life Carbon Assessment (WLCA) has become a vital method for quantifying embodied and operational GHG emissions. However, few studies have conducted WLCA on an urban scale, often addressing operational or embodied GHG emissions in isolation without considering their cumulative impact. This study introduces a city-wide WLCA framework to assess the potential recyclable materials of urban building stock, using Singapore as a case study with 5915 public residential buildings. Upfront GHG emissions are calculated from material intensity and building information, while operational emissions are based on energy use …

Erosion And Accretion: Mobilities Of Sand, People, And Memory At Queer Riis Beach, Jah Elyse Sayers

Dissertations, Theses, and Capstone Projects

The People’s Beach at Jacob Riis Park on the Rockaway Peninsula of Queens, New York, is a vibrant place of queer and trans public-space placemaking—and especially Black and working class queer and trans placemaking. A distinct queer ecology emerges in the interplay of the dynamic movement of the barrier island, queer and trans—especially queer and trans Afro-diasporic—mobilities. This queer ecology, while articulated with, also defies and exceeds logics and workings of private property. In response to a convergence of pressures on Black, queer, trans, and working-class placemaking on the beach site in the 2020s, beachgoers have mobilized longstanding provisional socialities …

Visualizing Ozone Pollution In The Denver Metro Area Using A Bioindicator Garden, Ella K. Mathews, Hillary Hamann, Julie Morris, Erica L. Larson

DU Undergraduate Research Journal Archive

Since the industrial revolution, widespread fossil fuel combustion has significantly increased atmospheric pollution. The combustion of fossil fuels releases nitrogen oxides (NOx) and volatile organic compounds (VOCs), which form tropospheric (ground-level) ozone when exposed to sunlight. Ozone directly harms plants by disrupting their ability to absorb carbon dioxide, release oxygen, and carry out photosynthesis. Bioindicator species are plants that have visible responses to environmental conditions, such as ozone, and can act as “canaries in the coal mine,” indicating the health of their environment. In this study, we used a garden of ozone bioindicator species (ozone garden) as a cost-effective tool …

Productive Armature, Gabriel Ofem Peter

Masters Theses

What if water was all you had, what if your only source of survival was a body of water? I shudder to think that some people get to be put in this situation in the world we live in. As I understand the importance of water to survival, it is obvious that water can be the only lifeline of survival for a community. This is the experience for residents of Makoko, Lagos. Their survival depends on the Lagos Lagoon, a large body of water flowing in from the Atlantic Ocean. This research looks beyond the surface of what this community …

Automation, Migration, And Development: Geography Of Job Precarity In South Asia And North Africa, Keshav Bhattarai, Ambika P. Adhikari

Himalayan Research Papers Archive

This article examines how accelerating automation and the adoption of artificial intelligence (AI) in advanced economies reshape labor markets across the Global South through interconnected channels of production, migration, and remittances. Drawing on the theories and practices of economic geography, labor economics, and development studies, the analysis conceptualizes automation as a transnational shock that contracts demand for migrant labor while simultaneously amplifying employment precarity in labor-surplus economies. The article advances a geographically grounded framework linking technology adoption in core industries with labor displacement, youth unemployment, and urban labor saturation in South Asia and North Africa. It further highlights the macroeconomic …

Dendroclimatic Response Of The Wet Miombo Woodland Species: A Case Study Of Mufulira District, Copperbelt Province, Zambia, Collins Chibuye Malubeni

All-Inclusive List of Electronic Theses and Dissertations

Zambia is a tropical, landlocked country that lies in the South-Central part of Africa. The climate in Zambia includes distinct dry and rainy seasons, mainly influenced by the north-south movement of the Intertropical Convergence Zone (ITCZ), which shifts seasonally. This research is focused on understanding the relationship between tree growth and climate using dendrochronology. Forty-nine tropical species, including Julbernardia paniculata, Brachystegia longifolia, and Pericopsis angolensis, were analysed for dendroclimatic potential, and 70% showed clear ring formation, indicating that trees in this locality produce distinct annual ring boundaries. For the single species chronology, thirteen cores from eight trees that were initially …

Redeveloping Mississippi: A Case Study On Brownfields In Central & Southern Mississippi, Sahrah R. Yeroozedek

Master's Theses

Brownfields, or properties that are or possibly are contaminated with dangerous materials, represent a common obstacle for communities in Mississippi. The real or potential presence of contaminants at these sites often deters investors due to costly cleanup requirements (EPA, n.d. -b). The Environmental Protection Agency (EPA), through its Brownfield Revitalization Program, implemented guidelines for covering the costs and labor associated with the remediation of these properties. The EPA is not, however, responsible for redevelopment that supports long-term environmental and economic sustainability. Although the EPA maintains inventories of all Brownfields, there is also no comprehensive database of Brownfields and their current …

Using Satellite-Observed Geospatial Inundation Data To Identify The Impacts Of Floods On Firm-Level Performance: The Case Of China During 2000–2009, Pao-Li Chang, Fan Zheng

Research Collection School Of Economics

This paper compiles high-resolution geospatial inundation areas of China for the period 2000–2009 based on satellite imagery repositories filtered by the Global Flood Database (GFD). In parallel, we geocode a comprehensive firm-level dataset of China and combine these two sets of geospatial data to identify the set of inundated firms in each year of flood events, as well as the distances of all non-inundated firms from the inundated areas. Given the high-resolution inundation data, we adopt a generalized dynamic-panel specification to estimate dynamic and spatial spillover effects of floods on firm-level production activities (including outputs, capital and labor inputs, and …
