Gradients Of Abandonment, William Tatman

Geography ETDs

As urban-rural disparities drive depopulation in rural areas worldwide, local strategies emerge as pathways for resilience. Research on Ojika, a Japanese island that has lost 75% of its population since the 1960s, reveals an Abandonment Gradient: a nuanced pattern of disuse adapted to modern polycrises. Extending the concept of "lying fallow" to homes and infrastructure, this thesis focuses on abandonment practices that reflect complex realities of labor, capital, and climate uncertainty. Rather than viewing depopulating communities as passive victims of out-migration, this paper argues they are critical sites for generating crisis response. Communally crafted attitudes toward unused space and more-than-human …

Who Bears The Burden: Tax Incidence And Water Governance In The Middle Rio Grande Conservancy District (Mrgcd) Within Bernalillo County, Michael W. Wilson

Economics ETDs

This study examines how property-value-based assessments within a large western irrigation and flood-control district distribute fiscal burdens across property owners. The empirical analysis is restricted to Bernalillo County within the Middle Rio Grande Conservancy District (MRGCD), using parcel-level administrative data from fiscal year 2025 merged with 2021 irrigation service records and geospatial information. The analysis classifies 34,397 parcels by irrigation status, agricultural valuation enrollment, and primary use to evaluate whether non-irrigating residential and commercial parcels, including renter-occupied properties that lack direct irrigation access, bear a disproportionate share of financial responsibility for a district whose first listed priority under their primary …

Understanding The Long-Run Effect Of Historical Redlining Practices, Yujian Lu

Geography ETDs

Historical redlining practices initiated by Home Owners’ Loan Corporation (HOLC) in the 1930s have produced enduring persistent socioeconomic and environmental disparities in U.S. cities. This dissertation examines their long-term impacts on social vulnerability, urban flood risk, along with public discourse about redlining practices. Results indicate that neighborhoods with HOLC grade A (greenlined) exhibit the lowest overall social vulnerability, while those graded D (redlined) face the highest across U.S. cities. In Chicago, associations between redlining practices and flood risk disparities are stronger than in Los Angeles, reflecting place-specific characteristics among environmental, socioeconomic, and demographic factors shaping flood risk disparities in long …

The Role Of Anticipatory, Preparatory, And Transformative Governance In Wildfire And Watershed Resilience Strategies, Robin Kundis Craig, Melinda Morgan

Natural Resources Journal

Wildfire is a game-changer for both communities and ecosystems throughout the West, including in New Mexico. Building resilience to increasing numbers of wildfire events, especially when wildfires can shift communities, ecosystems, and combined social ecological systems (“SESs”) past tipping points and into new regimes requires new approaches to governance. Focusing on the Hermit’s Peak/Calf Canyon fire and New Mexico residents’ ongoing response, this Article examines post-fire needs before surveying new modes of governance that can help to address those needs in a climate change era. It ends with a summary of our engagement with the participants in the “Life After …

Abstract

This dissertation examines how air quality and public attention to environmental shock affect perceived health status and healthcare utilization. The first chapter uses publicly available survey data from BRFSS and a triple difference framework to analyze the effects of the 2018 wildfire season in Oregon on self-reported mental and physical health. Findings indicate that those in Oregon in 2018, during the period of heightened attention to wildfire smoke, experienced approximately 1.4 additional poor mental health days, on average. The second chapter includes Merative MarketScan commercial insurance claims data to test whether these changes translate into a behavioral response. Results …

Agricultural Water Management, Farmer Decision-Making And Climate Adaptation In Dryland Agriculture: A Case Of The Middle Rio Grande Basin, Oluwatosin A. Olofinsao

Economics ETDs

Agriculture in dryland regions faces mounting pressure from climate change, water scarcity, and shifting land-use demands. The Middle Rio Grande Basin (MRGB) of central New Mexico exemplifies these challenges, where irrigated agriculture relies on increasingly variable surface water supplies. This dissertation examines agricultural water use, farmer decision-making, and adaptation strategies across farm types and climate conditions in the MRGB. The first study presents a spatial descriptive analysis of farm size, crop patterns, groundwater access, evapotranspiration (ET), and effective ET, revealing a landscape numerically dominated by smallholder farms that account for a substantial share of irrigation water use. The second study …

Heavy Metal And Metalloid Accumulation In The Gallinas River Following The Hermit's Peak / Calf Canyon Wildfire, Olivia A. Kelly

Geography ETDs

This study evaluates the persistence and bioavailability of heavy metals and metalloids in the Gallinas River three years after the Hermit’s Peak/Calf Canyon Wildfire of 2022 using a multicompartment sampling framework that includes water, sediment, and benthic macroinvertebrate tissue analysis via inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). Results indicate that the Hermit’s Peak/Calf Canyon Fire continues to influence the hydrogeochemical condition of the Gallinas River. Sediments contain elevated concentrations of several metals and metalloids, and these same elements are detectable in macroinvertebrate tissues, linking sediment contamination to biological uptake. Zinc (Zn), silicon …

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 …

The Role Of Gender And Salient Social Identities In Producing Vulnerability And Maladptation To Flooding In Koraso, Berekum, Ghana, Kingsley Damoah Oppong

Geography ETDs

This paper highlights how social identities like polygamy, illiteracy, and ethnicity hinder rural women farmers in Ghana from adapting to climate change. It advocates for an intersectional approach to address these challenges, moving beyond simplistic gender binaries. Using qualitative interviews (n=49) in a flood-prone village in Berekum, Ghana, the study reveals how these identities intersect with gender roles and colonial legacies, exacerbating vulnerability. It bridges Black feminist thought with climate change, an underexplored area, offering insights into climate change and environmental studies, as well as Black feminist scholarship. This research urges a reevaluation of how we understand climate change in …

Correcting Class Imbalance Through Synthetic Training Data And 3d Modeling For Carabid Pitfall Trap Sampling, Blair Mirka

Geography ETDs

Crowdsourced biodiversity data provide an accessible foundation for large-scale ecological monitoring, but class imbalance limits automated species identification, particularly for rare taxa. This research explores the use of synthetic training data generated from 3D models of carabid beetle museum specimens to improve detection and classification performance for underrepresented species in crowdsourced datasets. High-resolution 3D models were created to simulate variation in lighting, orientation, and background. These synthetic images were incorporated into convolutional neural network training datasets at varying synthetic-to-real ratios to assess their impact on classification accuracy. Models were evaluated using controlled pitfall-trap imagery to examine the influence of scene …

Electre I Approach For Multi-Criteria Group Decision-Making In Single-Valued Neutrosophic N-Soft Environment, Fathima Perveen P A, Sunil Jacob John

Neutrosophic Sets and Systems

The single-valued neutrosophic N-soft set model is a superior tool for capturing ambiguity and incompleteness in real-life circumstances. In this paper, we extend the ELECTRE I method to the single-valued neutrosophic N-soft ELECTRE I method in multi-criteria group decision- making environment. To explain the outranking relationship among alternatives with respect to different parameters, this new technique is developed by introducing the ideas of strong, midrange, and weak single-valued neutrosophic N-soft concordance and discordance sets. Also, we propose an algorithm for the proposed method along with a flowchart. Finally, an illustrative example is solved to validate and prove the relevance of …

Citizen Science Helps Monitor Urban Biodiversity: An Interactive, Data-Driven, And Open-Source Perspective, Katie Slack

Geography ETDs

Story maps, a powerful tool for communicating environmental narratives, are often commercial and lack many interactive functions. We integrate a data-driven and interactive geovisualization within an open-source story map created from high-attribute citizen science datasets. This story map creates a backend programming infrastructure for accessible, open-source science communication tools. Our story map intuitively communicates the findings from our web map application (app) portion of the story map to the public and helps reveal findings from the iNaturalist datasets. Albuquerque, New Mexico, United States is a demonstrative case study, but our tools can be flexibly adapted to other cities. Geovisualizations revealed …

Advancing Diamond Quantum Sensors: Isotropic Flux Concentrators And Phase Noise Mitigation, Maziar Saleh Ziabari

Optical Science and Engineering ETDs

Two methods for improving the sensitivity of nitrogen vacancy quantum sensors in diamond are explored. First, by passively concentrating the magnetic flux, three orthogonally oriented ferrite truncated cone pairs amplify the field isotropically by 19 times, allowing measurement of Earth's field without a bias field and increasing sensitivity. Through thorough analysis, modeling and tuning a novel 3-dimensional flux concentrator system, we achieve a fractional standard deviation of less than 1% anisotropy and quantify minimal deadzones and ambient temperature-limited variations below 40 nT/hour. Second, we characterize, model and calculate phase noise in NV experiments, which in NV sensors is effectively indistinguishable …

Thinking About Complexity In Latin America: Contributions Of Neutrosophy In Dialogue With Edgar Morin, Noel Batista-Hernández, Maikel Yelandi Leyva-Vázquez, Alenna Rosa Batista-Barallobre

Neutrosophic Sets and Systems

Smarandache’s neutrosophic logic—and its broader philosophical umbrella of MultiAlism, which insists that any assertion must be considered together with its neutral and anti-assertive counterparts—offers powerful methodological tools to operationalize Edgar Morin’s complexity thinking. While Morin contributes the principles of dialogic, recursiveness and the hologrammatic approach, his continental framework can be difficult to apply empirically. Neutrosophy and MultiAlism formalize contradiction, uncertainty and multidimensionality, thereby bridging theory and practice. In Latin America, where complexity thinking is widely adopted to address realities marked by inequality and instability, this integration enables rigorous modelling of non-linear phenomena. Applications such as Neutrosophic QCA (NsQCA), Neutrosophic Cognitive …
