Projecting Vegetation Condition And Fire Risk In Southern California, Westin K. Guthrie

Geography ETDs

In the western US, relationships between fire, vegetation, climate, and urban areas are dynamic and evolving. This work used a forest landscape model, LANDIS-II, informed by future climate scenarios and projections of urban expansion to understand wildfire interactions within projected Wildland Urban Interface (WUI) areas. This simulation showed that in both 2050 and 2100 +93% of the WUI in southern California experienced fire. Future work needs to be done in parametrizing forest biomass to ensure the validity of projections. Additionally, increasing each climate scenario model's replicates will create more accurate projections.

The Bearing Earth: Colonization, Conservation, And Political Ecology In Costa Rica (Coto Brus 1948 - Present), Pablo Alonso Arias-Benavides

Latin American Studies ETDs

This thesis presents two questions: How are relationships between people in Coto Brus and the land – specifically, forest – mediated by social, political, and economic forces? How are personal and collective identities expressed through relationship with the landscape? I chose Coto Brus because it is a forested region of Costa Rica which was populated with state support in the 1950s, and because it is my father’s hometown. In order to understand the subjective experiences of Costa Ricans involved in deforestation and reforestation, I performed interviews in the canton, visited conservation sites, and analyzed historical sources. This study combines multiscale …

The Affective Landscapes Of Herbalism In New Mexico, Samantha Angelou Stroud

Geography ETDs

Herbalism, or practices which use plants for medicinal purposes, is tied to traditions in several cultures of the American Southwest, including Indigenous herbal medicine, Mexican-American curanderismo, and Western herbal traditions. Herbalism has been steadily gaining mainstream popularity since the late 1960s, alongside counterculture, holistic health, and back-to-nature movements, introducing many newcomers to the practice. This study asks: How does herbalism create and attach meaning to plants, cultures, and place in New Mexico? What are the affective landscapes produced by herbalism in New Mexico? And, to what extent do meaningful attachments manifest in ethics and actions of care? I argue that …

The Manito Topos Project: Place Naming And Toponymic Silencing In The Sierras Of Northern Nuevo México And Southern Colorado, Len N. Beké

Spanish and Portuguese ETDs

This dissertation reports on documentary research on vernacular toponymies in Manito communities in Nuevo México and Colorado. These toponymies are erased, obscured and delegitimized in official maps. Within the study area, vernacular antecedents for 49.5% of official names for natural features were documented, along with 280 previously unmapped names. These data were compared to the state-sanctioned toponymy to determine a typology of linguistic mechanisms of toponymic silencing. While a majority of official toponyms are based on Manito oral tradition, only 15.4% of the labels for natural features represent unaltered versions of names in that tradition. This dissertation theorizes the conceptual …

Human-Centered Avalanche Susceptibility Mapping, Lindsey L. Rotche

Geography ETDs

With backcountry winter travel increasing in popularity, the importance of accessible avalanche safety information is crucial. Widely accessible avalanche backcountry maps use slope shading to show where avalanches are likely to start. Instead of focusing on the hazard of an avalanche starting in a specific location, this project shifted the cartographic emphasis of avalanche susceptibility maps to show risk to a human traveling in the terrain. I developed a methodology to incorporate possible avalanche runouts, terrain traps, and connected slopes while reducing false certainty of the visualization. To provide a more comprehensive representation of susceptible terrain, I integrated aspect, distance …

Nuanced Networks: How Social Relationships And Power Influence Participation In Private Lands Conservation Programs, Ellen Loechner

Geography ETDs

Because the majority of land in the Midwestern United States is privately owned, the responsibility for creating and maintaining space for wildlife conservation falls upon private landowners. Numerous state and federal agencies and non-governmental organizations (NGOs) host private lands conservation programs that offer landowners financial and technical support to complete conservation projects on their property (Echols, Front, and Cummins 2019). While the individual motivations and priorities of a landowner may inform how they use and manage their property, a landowner’s ability to connect with the agricultural and conservation communities may determine if they have the opportunity to participate in these …

Weedy Relations: Narratives Of Invasion And Intimacy With Tamarisk In The Chihuahuan Desert, Shannon S. Pepper

Geography ETDs

Tamarix spp., also known as salt cedar or tamarisk, is a shrub that has garnered a notorious reputation in North America as an invasive plant, with widespread policy and research advocating for its eradication in the Southwest U.S. and Northern Mexico. This study examines both governmental conservation documents and news articles to investigate narrative trends on tamarisk in the Southwestern U.S. and Northern Mexico as a contiguous region (the Chihuahuan Desert), expanding on current research to include transborder effects on the perception and management of introduced species. This paper asks: In the last 25 years, how has the movement, …

Individual Exposure Potential Assessment For Livestock Based On Spatial-Temporal Analysis Of Gps Data And Behavior Patterns Classification In Cove Wash Watershed, Arizona, Zhuoming Liu

Geography ETDs

This thesis examined the geospatial and temporal grazing patterns of domesticated livestock to model individual-level exposure potential to abandoned uranium mine (AUM) waste in a tribal community in the Southwest United States. Lotek Litetrack Global Positioning System (GPS) collars collected data at 20-minute-intervals for 2 flocks of sheep and goats during the Spring and Summer of 2019. Depending on the flock and individual animals, tracking time ranges from 10 days to four months. This research developed a GIS-based exposure potential framework that built on existing methodologies in time geography, GIS, and exposure mapping. This thesis aims to: 1) classify GPS …

The Bluff River Trail: A Community Land Ethic, Kelly F. Davis

Language, Literacy, and Sociocultural Studies ETDs

The Bluff River Trail (BRT) is a future 10+ mile trail along the San Juan River corridor in the 4-Corners region of the Southwestern United States. By asking, what is the land ethic of the Bluff Community? this qualitative study identifies behaviors and beliefs, or land ethics, between seven Bluff residents and the San Juan River corridor. A land ethic contributes to the social re/production of space; therefore, third space theory contextualizes intersecting and contradicting spatialities evidenced in data. Data collection consisted of semi-structured interviews, questionnaires and focus groups. I used a qualitative content analysis pulling from grounded theory to …

How Do Farmers Experience Agroecology In Rural Communities Of Northern Ecuador?, Neil Michael Ayala Ayala

Latin American Studies ETDs

Agroecology, a concept in continuous evolution embraces science, practice and sociopolitical aspects. Its meaning is gaining space of debate and global interest as an alternative for building sustainable food systems and resilient communities, not only from the environmental perspective, but from all the dimensions of sustainability. The Andes region is recognized for its agrodiversity and for its history of agricultural activity; nevertheless, the effects of unsustainable agricultural practices inspired in the principles of the so called “Green Revolution” are evident. Conventional agriculture has decreased the capacity of resilience of the agroecosystems and their associated communities. Agroecology is often perceived as …

Drinking Water Governance For Whom? An Institutional Analysis Of Rural Drinking Water Systems In New Mexico, Tucker Colvin

Geography ETDs

Rural community drinking water systems in New Mexico are facing many challenges, including a lack of personnel, deteriorating infrastructure, lack of funds, overly burdensome and confusing regulation, environmental concerns, and concerns over water rights. Governing agencies are creating vulnerability by making managers prioritize some issues and neglect others. Water systems designated a Mutual Domestic Water Consumers Associations are especially problematic because they are small and managed by volunteers but have as much regulatory burden as larger municipalities. I use the theory of institutional work to explain how an institution that was originally designed to help low-income and rural communities is …

Backyard Wildlife Refuges In Albuquerque, Nm: An Urban Land Ethic In Practice, Laurel E. Ladwig

Geography ETDs

In the urban setting, biodiversity conservation requires intentionally creating spaces humans and wildlife can share. An urban land ethic can guide this process. Developing and practicing this ethic requires asking questions that consider approaches from multiple disciplines and avoid anthropocentric framing. Both More-Than-Human and Critical Physical Geography bring multiple knowledges into conversation to make complex realities visible. This project explores these fields of scholarship as guides for reconciling the needs of the land community.

Sharing familiar spaces creates opportunities for developing ethical relationships between humans, non-humans, and natural systems. Wildlife gardening creates habitat in our residential and community areas, providing …

This dissertation uses a feminist political ecology perspective to explore the socioeconomic impacts of climate change in Ecuador, especially but not limited to the agriculture sector. It is based on the use of mixed methods that allowed the participation and validation of the local population, surpassing their role as beneficiaries to co-authors of this research.

The significance of this study relies on the position the local population holds in the fields of human geography, under a community local-planning perspective, as they attempted to collaborate in the process of adaptation to climate change by presenting analysis and calculation of an index …

A Hybrid Gis/In Situ Analysis Of Aed Coverage On The Unm Central Campus, Ian T. Hill

Geography ETDs

Automated External Defibrillators (AED’s) are lifesaving devices that can greatly improve the survival rates of cardiac arrest when used quickly. There are publicly accessible AED’s on the UNM campus, and each device has an effective range based on how quickly a responder can retrieve the AED and return it to the site of the cardiac emergency. The ranges of the AED’s on UNM central campus are analyzed using GIS, interior building measurements, and various retrieval speeds. This helps evaluate the current placement of AED’s on campus and helps reveal where future coverage is needed. This focus on the combined navigation …

Assessing How Terrain Representations And Scale Affect The Accuracy Of Distance Estimates, Kristian Mueller

Geography ETDs

Terrain is often displayed on maps either as background or foreground. Although terrain representations are ubiquitous, there is not a thorough understanding of map-readers’ cognition of geographic surfaces from various terrain representations. The research described in this thesis empirically assessed map users’ abilities at estimating straight-line distance using maps with two different types of terrain representations and at three different scales. The objective of this research was to assess how accurately map users estimate distance on the ground taking into account variations in elevation. Participant data in the form of demographics and distance estimates were statistically analyzed to determine if …

La Gota Que Colma La Caguama: Cummulative Tensions Transformed Into The Defense Of Water, Anthony J. Meluso

Geography ETDs

Making water management decisions is often where dreams and visions about potential futures are constructed and contested (Swengedouw 2015). However, in a globalized world, it is not well understood how people can challenge dominant paradigms to shape desirable futures when they are also complicit in, and dependent on existing structures (Arts & Buizer 2009; Emery, Perks, & Bracken 2013: Kleinschmit, Böcher, & Giessen 2009). This project examines a brewery conflict in the Mexicali Valley that provides an example of how protesters were able to challenge dominant assumptions about water management in a complex, globalized environment. I draw on Laclau’s (2005) …

Engaging Sacred Space And Experiencing God In The Mountains: A Study Of The Non-Traditional Worship Environment Of Mountain Cathedrals, An Ecumenical Meetup Group Based In Albuquerque, New Mexico, Brendan Isaiah Nixon

Geography ETDs

This paper focuses on the non-traditional Christian worship site of Mountain Cathedrals in Albuquerque, New Mexico. I argue that affectual and emotional responses are elicited from the congregants of Mountain Cathedrals through the process of sacralization. It is shown that Christian worship in a non-traditional outdoor setting affects the ways in which the congregants engage with, participate in, and create sacred space. I survey current literatures of sacred space, the contemporary Christian church, and non-traditional worships spaces. Using the literature as a backdrop, I utilize Mountain Cathedrals as a case study for understanding the ways in which sacred space is …

Translating Global Nature: Territoriality, Environmental Discourses, And Ecocultural Identities, José R. Castro-Sotomayor

Communication ETDs

In this study, I explore environmental discourses circulating among Indigenous transboundary organizations working on environmental initiatives at the border between Ecuador and Colombia. I focus on three global environmental discourses –sustainability, development, and climate change– as they are at the core of the global environmental governance vernacular. La Gran Familia Awá Binacional (GFAB), one of the few transboundary Indigenous organizations working along the binational border, utilizes these global concepts to frame their environmental initiatives and projects. I use a critical and interpretive qualitative approach to investigate, deconstruct, and rearticulate global environmental discourses circulating among and translated by two of the …

How The Proximity Of Crime Impacts Housing Prices: A Hedonic Pricing Study Of Inner-Loop Houston, Tx., Samuel D. Thompson

Geography ETDs

This research used data on over 2200 house sales in inner-city Houston, TX to estimate the impact of crime on house prices. A GIS was used to tabulate home sale data from the MLS, neighborhood characteristics and crime data published by the Houston Police Department. Hedonic Pricing Models were built to assess how crime effects housing price and if proximity to the criminal event matters. Results show that crime does have a measurable impact on home sale price and that proximity of crime is important. An increase in number of violent criminal events leads to a discount in home price. …

Virtuous Discourse In The Specialty Coffee Sector: How Social Responsibility Practices Fragment Pursuits For A Supply Chain, Jane H. Motsinger

Geography ETDs

A diversity of public and private initiatives strive to address the human-environment challenges confronting the global coffee industry, including certifications like Fairtrade, direct trade sourcing models, and efforts led by NGOs. Research examines the outcomes of major certification programs and the private initiatives of corporations like Starbucks. Much less is known about the business practices of the small specialty coffee businesses that increasingly advertise sustainable business practices. Yet, their collective business practices likely influence the industry-wide efforts to achieve a sustainable supply chain. This research examines how small specialty coffee roasting and importing companies represent their socially responsible business practices …

Three Essays On Understanding Municipal Water Demand In The Western United States, Michael J. O'Donnell

Economics ETDs

Scarce water resources in the Western United States, in concert with population growth and climate change, constitute a need to better understand factors that impact water demand. In this dissertation, Chapter 1 provides cultural and historical context for water use in the West and argues that understanding water demand is important, especially when managing scarcity is a goal. Chapter 2 uses aggregate city-level data from four municipalities in New Mexico to investigate seasonal trends and breakpoints. Although per premises and aggregate demand tend to decline in all geographies investigated, existence and timing of breakpoints varies by geography. Additionally, drivers of …

Impact Of Drought On Land Cover Changes In Diné Bikéyah – A Study Through Remote Sensing, Anjanette A.J. Hawk

Geography ETDs

This study identifies land cover changes associated with a ten-year drought period and discusses the importance of vegetation change in Diné Bikéyah, a semi-arid land located in a remote part of the southwestern United States (US). This study concludes that drought produced slight changes in vegetation within a 540 km² study area in the Tselani-Cottonwood Chapter (TCC) in Diné Bikéyah. The data for this study consist of three Landsat images for the years 1998, 2002, and 2009. The methods used to analyze these Landsat images included image pre-processing, calculation of normalized difference vegetation index (NDVI) images, and supervised (maximum …

The Ivory Tower, Urban Growth, And State Subjugation: An Historical Analysis On The Construction Of Student Identities And The Public Good During University Generated Redevelopment Projects, Jacob R. Wolff

Geography ETDs

Having become almost cliché in academic discourses, the term gentrification offers a conceptualization of sociospatial transformation too narrow for contemporary understandings of inequality within the post-industrial city. Generalizations of a wealthy populous displacing working-class and marginalized populations fail to address the diversity, complexity, and scope of economic hollowing-out and fail to fully account for other incoming subpopulations such as the emergent “creative class,” comprised of university-educated individuals who are not necessarily considered affluent by traditional economic measures. To this end, scholars in the United Kingdom have identified university neighborhood formation as a significant yet distinct process of place production that …

Pavement Surface Distress Detection, Assessment, And Modeling Using Geospatial Techniques, Su Zhang

Civil Engineering ETDs

Roadway pavement surface distress information is essential for effective pavement asset management, and subsequently, transportation agencies at all levels dedicate a large amount of time and money to routinely collect data on pavement surface distress conditions as the core of their asset management programs. These data are used by these agencies to make maintenance and repair decisions. Current methods for pavement surface distress evaluation are time-consuming and expensive. Geospatial technologies provide new methods for evaluating pavement surface distress condition that can supplement or substitute for currently-adopted evaluation methods. However, few previous studies have explored the utility of geospatial technologies for …

Human Experience Of Fountain Spaces In Denver And Albuquerque, Susanna Diller L

Geography ETDs

Concerns about water have been at the forefront of public conversation over the last few years, in no small part driven by situations like the drought in California. The drought prompted cities like Los Angeles to turn off public fountains, even though fountains have a very low resource impact. This interaction is more about what a fountain represents; particularly in dry regions, fountains have been used to display power, affluence, and social importance. It has been researched and is now taken for granted that public fountains are a public good, improving microclimates, reducing stress, and adding to the overall quality …

Forests On The Edge: Forest Restoration And Concepts Of Nature In Northern New Mexico, Jordan W. Stone

Geography ETDs

Dozens of catastrophic forest fires have impacted New Mexican communities over the last two decades, threatening humans, property, and livelihoods. Ecologically, forest systems are stressed by historically unprecedented tree density, drought, increased temperature, and dwindling ecological diversity, further increasing fire danger. An increasingly common response to these threats is to actively manage New Mexico’s forests using mechanical tree thinning and prescribed fire, with a goal of “restoring” forests to a healthier ecological state. Restoring forests is both a scientific and cultural act. While the science is well studied, land managers often struggle to understand how human values impact forest restoration …
