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 …

Marine Geophysical Studies Of Coupled Tectonic And Sedimentary Processes At Active Plate Boundaries, Sarah R. Rysanek

Earth and Planetary Sciences ETDs

Deep-sea and convergent margin sedimentary systems preserve critical records of tectonic and climatic processes that shape Earth’s surface. This dissertation investigates source-to-sink sediment routing and forearc deformation to better constrain the interplay between sedimentary and tectonic processes, through investigations of a deep-sea fan system, and the forearc geomorphology offshore Nicaragua. In the Gulf of Alaska, we integrate ultra-long-offset and regional multi-channel seismic reflection data, multi-resolution bathymetry, and plate reconstructions to remap the Baranof Fan system. Results show that the fan is larger than previously recognized and constructed by two primary depocenters linked to distinct glacial sediment pathways, with accommodation space …

The Formation Of Indian Health Services Within Imperial And Settler-Colonial Contexts, Jillian E. Grisel

American Studies ETDs

This dissertation examines the Indian Health Services as a Cold War biosecurity apparatus, showing how infectious disease was weaponized to dismantle treaty obligations, reorganize tribal lands into “service areas,” and reclassify Indigenous nations as surveilled populations. Against this carceral health economy, Indigenous nations refused. From the 1969 Alcatraz occupation to the 1976 Puyallup takeover of Cushman Indian Hospital, Native activists reclaimed health facilities as sovereign spaces, insisting that care is not a discretionary service but a treaty right grounded in land and kinship. Methodologically, I combine historical-legal analysis of congressional debates, Public Health Service reports, and IHS data with counter-archives …

Investigating Workforce Development Gaps In Tribal Transportation Agencies, Benson Long Jr

Civil Engineering ETDs

Tribal transportation programs face challenges in recruiting and retaining qualified staff, prompting reliance on external consultants for key responsibilities. This study explores how workforce constraints and organizational structures influence tribal outsourcing decisions. Survey data from 57 tribes informed a logistic regression model examining how geographic isolation, population size, training access, and the presence of a transportation department affect preferences for internal work, actual task completion, and instances where tribes intended to perform tasks in-house but outsourced instead. Findings indicate that outsourcing is driven by limited internal capacity, including staffing shortages, lack of certified personnel, and training opportunities. Geography also plays …

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 …

Realizing The Long Wavelength Array Swarm, Craig Anthony Taylor

Physics & Astronomy ETDs

Sensitive modern radio interferometers are costly to build and operate at the university level. The `swarm telescope' concept addresses this challenge by enabling the collaborative use of individual telescope systems, overseen by separate institutions, that come together to form a more powerful and manageable facility. This dissertation focuses on demonstrating this concept using the Long Wavelength Array (LWA) by commissioning an aperture synthesis telescope consisting of interconnected LWA stations, called the LWA Swarm. The presented work details building a cost-efficient prototype LWA platform -- the LWA--North Arm station -- to enable synthesis imaging using the 3-element interferometer comprised of LWA1, …

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 …

Exploring Policy Change To Support Early Diagnosis Of Congenital Heart Defects (Chd) In New Mexico, Kelsey Carson Leibenhaut

Doctor of Nursing Practice Scholarly Projects

Congenital heart disease (CHD) is not a new or rare problem; it has likely always been a leading cause of childhood morbidity and mortality and clocks in today as the most frequently occurring birth defect, affecting an estimated 1 in 100 newborns (CDC, 2025). Prior to the middle of the 20th century, there was little to be done about CHD, as no treatments existed. Everything changed with the advancement of options for surgical repair of CHDs, significantly prolonging lifespans and improving quality of life for affected individuals. Despite these incredible advancements, babies are born with CHD every day, leading to …

Identidad Flamenca: Formation Of And Negotiations With The Flamenco Identity, Kayla Lyall

Theatre & Dance ETDs

The core of this dissertation is an inquiry into belonging in flamenco. Expanding beyond the personal, it examines how flamenco identity is constructed through embodiment and practice. Challenging dominant narratives of purity and authenticity, I argue that identity in flamenco emerges through multiple pathways—including inheritance, training, cultural proximity, and artistic inquiry—and is continually reshaped by social, political, and aesthetic forces. Through phenomenology and practice-as-research, I position the body as an archive of knowledge and a site of meaning-making. My creative project, NUDE, serves as an embodied investigation into vulnerability, lineage, and self-definition, demonstrating identity as something enacted rather than …

Rural Transformations And Identity In Northern New Mexico, Eva Gemrich

Geography ETDs

In the U.S. West, research points to a significant transformation of rural places, including rural blight, a decline in extractive industries, and changing migration patterns. In Northern New Mexico, these rural transformations are occurring alongside a long and continuing history of tensions and conflicts relating to land, water, and property regimes, which are intertwined with notions of identity, culture, and power. Using participant observation and semi-structured interviews, this thesis explores how rural transformations, particularly shifting land ownership, have influenced identities and cultural values along the Upper Rio Chama in Northern New Mexico. I find that comparatively wealthy in-migrants are purchasing …

From Our Stories, To Our Streets (Osos), Jennifer Lopez

Student Publications

Youth traffic safety persists as a critical planning challenge and public health concern in New Mexico, where pedestrian fatality rates consistently rank among the highest in the United States (National Highway Traffic Safety Administration, NTSA, Governors Highway Safety Association, GHSA, 2023; Baca, 2025). Students (children), due to their daily interactions with roadways, whether when they walk, bike, ride transit, or drive/get driven to and from school, are among the most vulnerable groups within the transportation system (Ferenchak, N. Wesley, M., 2017. For many students in Albuquerque, the commute to or from school is one of the most dangerous parts of …

The Road Less Traveled: The Path To A Right Of Intrastate Travel In State Constitutions, Katherine S. Leung

New Mexico Law Review

The existence of a right of intrastate travel implicates basic liberties like visiting parks, driving to visit family in another city, going to church or the doctor, or voting. In addition to its importance to everyday, basic liberties, the right of intrastate travel is important for vulnerable populations, like disaster evacuees, unhoused people subject to displacement, and people seeking abortions in states without uniform availability, like New Mexico. Despite the essential nature of the implicated actions, federal courts do not agree on whether the U.S. Constitution guarantees the right of intrastate travel. This comment argues that the right of intrastate …

Protection Forests: Intersections Of Law And Science, Jamison E. Colburn

Natural Resources Journal

The national forests of the eastern United States are where and what they are today based in good part on a mistake. When they were being acquired and established in the early twentieth century, hydrology was in its infancy. Yet many hydrologists and their students in government were promising that these forests would provide significant protection from floods. They promised more than they should have. Forests as protection from floods were embroiled in a contentious and prolonged factual inquiry almost immediately thereafter. Indeed, that inquiry would later mature into a distinct scientific subfield, forest hydrology, that went on to influence …

A Historical Analysis Of The Squatter Settlements (Sukumbasi) In Nepal And The Role Of Smart Settlements, Keshav Bhattarai, Ambika P. Adhikari

Himalayan Research Papers Archive

In Nepal, landless populations can broadly be categorized into two groups: urban squatters and rural landless families. Each group can further be distinguished by its level of political connection and access to power.

Among urban squatters, politically connected groups often occupy open public spaces in cities with some degree of protection or tolerance from political parties. In contrast, less powerful urban squatters usually settle on public land because they cannot afford formal housing. These settlements are commonly located in unsafe or marginal areas, such as riverbanks, flood-prone zones, and unused public spaces. Despite these risks, many remain in urban areas …

Urban Shadows In Latin America: Detection Of Crime Hotspots Using Multivariate, Geospatial, And Neutrosophic Analytic Hierarchy Process (Nahp) Analytical Techniques, Johnny Pambabay-Calero, Sergio Bauz-Olvera, Oscar Scott-Macías, Pedro Luzuriaga Cedeño, Purificación Galindo-Villardón

Neutrosophic Sets and Systems

In recent years, Guayaquil fell prey to higher levels of organized extortion compared to territorialized criminal organizations over territory, institutional weaknesses, and socio-spatial inequalities. Thus, while extortion emerged as an increasingly specialized crime, there are limited empirical studies to evaluate the crime's spatiotemporal nature or its determinants. Therefore, this study aims to identify and characterize extortion "criminal severity zones" of Guayaquil from 2021-2024, via a novel geostatistical approach, in addition to the Neutrosophic Analytic Hierarchy Process (NAHP). By implementing Exploratory Spatial Data Analysis (ESDA), Kernel Density Estimation (KDE), dimensionality reduction techniques (PCA, MDS, and t-SNE), hierarchical clustering, and Bayesian hierarchical …

Designing Optimal Routes For Mobile Prenatal Care Clinics Using Neutrosophic Cognitive Maps, Mónica Gabriela Chachalo Sandoval, Evelyn Paulina Chacha Ochoa

Neutrosophic Sets and Systems

This manuscript examines the routing of mobile prenatal clinics in Ecuador, focusing on maternal and infant health in vulnerable, hard-to-reach areas. This assessment is significant because even with new developments geographically expanding access to mobile prenatal clinics, there remain accessibility gaps for vulnerable women located in hard-to-reach, topographic regions where it's uncertain if they truly need services or can assess whether they can travel to a clinic. While previous studies sought to assess the potential for newly mobile units and coverage, few studies have been found to assess new routes through accessibility uncertainty and villages with varying demand for access …

Irregularities In The Dynamics Of Large Networks: Cases On Social Networks And The Internet, Dheeman Saha, Abdullah Mueen, Shuang Luan, Afsah Anwar, Yangsun Hong

Computer Science ETDs

Dynamic networks capture evolving relationships among entities, and irregularities in their behavior often signal significant events. This dissertation investigates such irregularities across social and infrastructural networks. First, we analyze Twitter (prior to its rebranding to X) to characterize influencers, introducing a follower-overlap similarity measure that identifies micro-influencers beyond content-based methods.

We then examine election-related irregularities by comparing suspended and non-suspended accounts during the 2020 U.S. presidential election, revealing behavioral patterns linked to misinformation and coordinated manipulation.

Next, we develop an algorithm to infer post-specific diffusion networks, reconstructing who-saw-from-whom pathways for tweets at scale. This method uncovers structural differences in diffusion …

Un-Imagining The Anglo Southwest And The Impossibility Of Trans-Scription, Lynnette M. Maphies

Art & Art History ETDs

This thesis is an interrogation of the Anglo Southwest as a problematic and persistent regional and national construct. I propose that the Anglo Southwest emerged at a pivotal moment in the late nineteenth century during which Americanist approaches to geography, anthropology, and the arts, were being shaped to define the region and determine the production and distribution of knowledge. This resulted in an Anglo view of the Southwest as uninhabited, silent, and imaginary, which omitted the actuality of silencing Native voices, cultural appropriation, and the taking of resources and land. Army surgeon and amateur ethnographer Washington Matthews (1843–1905) serves as …
