Deep Roots In Eroding Soil: Building Decolonial Resilience Amidst Climate Violence And Displacement In A Louisiana Bayou Indigenous Community, Lia Mcgrath Kahan

Senior Independent Study Theses

The Pointe-au-Chien Indigenous community of coastal Louisiana is fighting for survival as climate change and socio-political factors threaten to displace them from their ancestral home. This project takes an ethnographic and historical approach to exploring how colonization and climate change have influenced Pointe-au-Chien tribal members’ ability to stay on their ancestral land. Climate projections estimate that the bayou this community has lived alongside of for generations will soon be unrecognizable, leading to potential displacement and devastating cultural loss. Due to the increasing severity of climate change, it is crucial to look to the experiences of frontline Indigenous communities to support …

Impacts Of Transit-Oriented Development Through The Eyes & Lives Of Low-Income Latinx Residents: A Case Study In Fruitvale, Oakland, Diana Saavedra

Master's Theses

Transit-oriented development (TOD) is often showcased as a solution for private vehicle dependency and growing climate issues. Although TOD seems promising, it usually has harsh, unforgiving effects such as ecological gentrification. Ecological gentrification occurs when lower-income communities, especially of color, are pushed out of their neighborhoods due to the implementation of an environmental amenity, benefit, or service. However, research suggests that TODs that apply Transportation Justice principles seem to produce more equitable results. This study explores the Fruitvale Village TOD, located in Fruitvale, Oakland, California. This TOD was selected because it is unique in its conception and implementation, as it …

Historic Ohlone Resource Distribution Within The Alameda Creek Watershed, Naseem Fazeli

Master's Theses

The Alameda Creek watershed is located within the ancestral homeland of the Muwekma Ohlone Tribe of the San Francisco Bay Area. Their ancestors historically utilized a variety of plants for food, medicine, ceremonies, and building materials, with their understanding of the value of the plants based on traditional ecological knowledge (TEK). The arrival of Spanish, and later Anglo/American, colonists beginning in the mid-18th century introduced urbanization and European agricultural practices, which have degraded wildlands and impacted species richness and diversity. As interest in environmental restoration has been increasing in recent decades, the present-day Muwekma Ohlone Tribe has an opportunity to …

Black, Green, And Young: A Case Study Assessing Implementation And Outcomes Of An Environmental Science, Technology, Engineering And Math Curriculum For Youth In West Oakland, California, Ashari A. Taylor-Watson

Master's Theses

Environmental racism plagues low-income communities of color through exposure to environmental hazards, and the youth are most vulnerable. Environmental science, technology, engineering, and math (E-STEM) curriculums promoted as tools for corrective justice. Using a West Oakland, California Boys and Girls Club as a case study, I first describe the environmental awareness, attitudes, and actions of a group of six- to 13-year-old, predominantly African - American, children from this low-income community. I then examine the possible impacts of an E-STEM curriculum on participants, and I identify staff- and researcher-identified challenges to its implementation. During the study, the cohort experienced a heightened …

Co-Composted Biochar Improves Dry-Farmed Tomato Productivity In The Santa Clara Valley, Ca, With No Change In Soil Microbiology, Duncan A. Keller

Master's Theses

California is a globally important site for agricultural production, but the state is currently suffering from an unprecedented drought. One strategy to conserve water is dry farming, where growers cache moisture in the soil from off-season rain or early-season irrigation for crops to use throughout the growing season. Some California growers have dry-farmed tomatoes for decades. Recently, some have begun adding co-composted biochar (COMBI) to boost productivity and stimulate soil microbiology, particularly arbuscular mycorrhizal fungi. To the best of my knowledge, no field research on dry-farmed tomato systems currently exists, let alone on the effects of COMBI amendments on yield, …

Use Of A Utility-Scale Solar Energy Facility By Avian Populations In Central California, Quratulain Ahmed

Master's Theses

With an ever-increasing demand for renewable energy in response to climate change, utility-scale solar energy (USSE) is on the rise, particularly in California. Although solar energy is viewed as an essential resource for transitioning from a fossil fuel economy, USSE installations can cover thousands of acres of habitat used by avian species. Little is known about the effects of USSE on avian populations, although some evidence suggests that USSE facilities may be leading to bird mortality. The lake-effect hypothesis suggests that birds may mistake solar arrays for large bodies of water resulting in injury or mortality. Though several studies describe …

Water Woes Worsen: Middle Rio Grande Reservoir Modeling Projects Declining Water Availability Under Climate Change Simulations, Robyn Holmes

Dissertations, Master's Theses and Master's Reports

The Middle Rio Grande is a vital source of water for over 2M people. Climate change is impacting regional hydrology and is likely to put additional stress on a water supply that is already stretched thin. To gain insight on future water availability, a simple water balance model was used to simulate the Elephant Butte-Caballo reservoir system (Southern New Mexico, USA). The water balance model was run under 97 climate simulations derived from Global Climate Models (GCMs) developed under the Intergovernmental Panel on Climate Change's (IPCC) 5^th generation Coupled Modeling Intercomparison Project (CMIP5). Results suggest that the percentage of …

Utility Scale Agrivoltaics Development Proximate To Michigan Communities With 100% Renewable Energy Goals, Kabanda Herve Christian Sheja

Dissertations, Master's Theses and Master's Reports

This report aims to assess the potential of agrivoltaics (combined solar and agricultural systems) for development geographically proximate to the six Michigan (MI) communities that have set 100% renewable energy (RE) goals. I focus on one major research question: What is the total acreage of low-impact sites available for utility-scale (USS) agrivoltaics development proximate (within county boundaries) to MI communities with 100% RE goals? SAM is used to estimate land acreage required for a 10 MW agrivoltaic system development. ArcGIS Pro is used to determine the total acreage of low-impact sites proximate to MI communities with 100% RE goals.

Animal Sentience In Indian Culture: Colonial And Post-Colonial Changes, Nanditha Krishna

Animal Sentience

The Indian tradition has respected animal sentience and non-injury toward all life. It is repeated consistently in Sanskrit literature and the later literature of the Jains and the Buddhists. Change came with the advent of Islamic rule followed by the British, who built slaughterhouses. The hunting of wildlife increased and several wild predator species were wiped out. The result was the series of legislations for animals which were initially proposed by the SPCAs and later by NGOs. In 1976, the Constitution of India was amended to make the protection of wildlife and compassion for living creatures a fundamental duty. However, …

Land use is central to addressing sustainability issues, including biodiversity conservation, climate change, food security, poverty alleviation, and sustainable energy. In this paper, we synthesize knowledge accumulated in land system science, the integrated study of terrestrial social-ecological systems, into 10 hard truths that have strong, general, empirical support. These facts help to explain the challenges of achieving sustainability in land use and thus also point toward solutions. The 10 facts are as follows: 1) Meanings and values of land are socially constructed and contested; 2) land systems exhibit complex behaviors with abrupt, hard-to-predict changes; 3) irreversible changes and path dependence …

Soil Drought Can Mitigate Deadly Heat Stress Thanks To A Reduction Of Air Humidity, Jeremy Pal, Hendrik Wouters, Jessica Keune, Irina Y. Petrova, Chiel C. Van Heerwaarden, Adriaan J. Teuling, Jordi Vilà-Guerau De Arellano, Diego G. Miralles

Civil and Environmental Engineering Faculty Works

Global warming increases the number and severity of deadly heatwaves. Recent heatwaves often coincided with soil droughts that intensify air temperature but lower air humidity. Since lowering air humidity may reduce human heat stress, the net impact of soil desiccation on the morbidity and mortality of heatwaves remains unclear. Combining weather balloon and satellite observations, atmospheric modelling, and meta-analyses of heatwave mortality, we find that soil droughts-despite their warming effect-lead to a mild reduction in heatwave lethality. More specifically, morning dry soils attenuate afternoon heat stress anomaly by ∼5%. This occurs because of reduced surface evaporation and increased entrainment of …

Indigenous Ecocriticism And The Relationships Between Humans And Nature In Catherine Knutsson’S Shadows Cast By Stars, Kerri Nicole Nelson

English

In the midst of the climate crisis, Young Adult dystopian literature offers a glimpse of the possible dark futures in store for all of us. Yet Indigenous Young Adult literature revises the natural world not as the enemy of the survival of human beings, but as a possible ally. In Cassandra Knutsson’s Shadows Cast by Stars, a plague is raging and Indigenous blood is key to human survival. Through her journey to save her community, Cassandra demonstrates how she builds a more positive relationship with nature. By offering alternative possibilities for how to treat and interact with nature, Shadows Cast …

The Persistent Objector Doctrine: Identifying Contradictions, Shelly Aviv Yeini

Chicago Journal of International Law

The persistent objector doctrine (POD) in international law provides that a rule of customary international law (CIL) will not oblige a state that has persistently objected to the development of the rule. The doctrine requires that the objection be “persistent” and “consistent” and that it not be contradictory. Yet, while in this context the meaning of persistency and consistency, in this context, has been discussed in the legal literature, the term “contradiction” has not. Therefore, it is not clear what type of behavior would represent a contradiction that would disqualify a state from persistent objector (PO) status. In practice, this …

Genetic Analysis And Telemetry Study Of Migration Habits Of The Endangered Atlantic Sturgeon, Cassia Marie Busch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Atlantic sturgeon are a long-lived anadromous fish that ranged from Labrador, Canada to Florida, US. Due to overharvest in the late 1800’s and 1900’s, Atlantic sturgeon populations across the coast experienced a dramatic population crash. Recovery of this species has faced challenges due to anthropogenic threats, such as vessel strikes, bycatch, and habitat degradation. In 2012, Atlantic sturgeon were added to the United States Endangered Species Act (ESA). Under the ESA, populations were listed as five distinct population segments (DPS), reflecting their geographic arrangement and genetic structure: Gulf of Maine DPS (threatened), New York Bight DPS (endangered), Chesapeake DPS (endangered), …

Land Is Life: Settler Colonial Governance Of National Parks And Hunting In Taiwan, Wei-Chieh Jarita Chen

Environmental Studies Honors Projects

This thesis situates Taiwan as a settler colonial state by examining the discourse around the governance of national parks and the criminalization of Indigenous hunting. Placed in the context of historical patterns of land dispossession and cultural genocide, these two issues represent the ongoing process of settler colonialism and the reproduction of settler colonial relations through environmentalism. I focus on the narratives around three case studies: the controversial and ultimately unsuccessful campaign for the Maqaw National Park, the Tumpu Daingaz buluo’s struggle with the Yushan National Park, and the Tama Talum Indigenous hunting constitutional reinterpretation case. I argue that settler …

Using Poultry To Enhance Food Security In Stann Creek, Belize, Emily Spatz, Lisa S. Wood

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Food insecurity is a growing issue in developing and developed countries alike, and in countries like Belize, the prevalence of hunger has soared in recent years. Not having access to diets with sufficient calories and nutrients leads to a host of developmental issues, including stunting and cognitive delays. The purpose of this work was to create an all-encompassing manual for small-scale poultry production in order to provide nourishment for the students and staff of a school in Belize. After determining that the best way to meet the school’s needs was through dual-purpose birds, background research was conducted to determine small-scale …

Wet, Flowering, Dry, Caroline A. Minchew

Theses and Dissertations

Wet, flowering, dry is a series of photographic works that explore how vernal pools are a macrocosm for holding memory and a site of omnipresent solitude and decay. This installation distills an embodied and ephemeral experience of how we are grounded in a network of invisible connections with our surroundings. This network becomes evident through biological, historical, and field research conducted at the vernal pools for over a year. Through slow observation and consideration of how multiple stories of place can weave together into a larger parable, Wet, flowering, dry reveals how the life cycle of a vernal pool is …

A Rising Tide? The Role Of Alternative Networks For Women Oyster Farmers In Maine And New Hampshire, Natalie Lord

Master's Theses and Capstones

Aquaculture is one of the fastest growing forms of food production globally. In the United States, there has been a renewed interest in aquaculture development in domestic waters. With widespread expansion of shellfish aquaculture started by local entrepreneurs and fishermen, the states of Maine and New Hampshire have experienced aquaculture driven economic development in coastal communities impacted by the decline in wild capture fisheries. Additionally, aquaculture farming practices can provide ecosystem services such as water quality improvement, nutrient removal, and habitat availability. When implemented carefully, marine food products from aquaculture can be among some of the most environmentally responsible choices …

Texas Stakeholders’ Knowledge And Perceptions Of Chronic Wasting Disease Risks: Implications For Wildlife Agency Communications, Elena C. Rubino, Christopher Serenari

Human–Wildlife Interactions

Chronic wasting disease (CWD) is a fatal neurological disease impacting cervids. The disease can move swiftly through populations, making CWD management a priority for wildlife agencies across the United States. Stakeholder perceptions of CWD may shape behaviors that can negatively impact wildlife agencies. Thus, agencies need comprehensive assessments of stakeholder risk perceptions and enhanced understandings of how perceptions are formed to improve communications. Using a mail- and online-based questionnaire to collect data from September 2020 through January 2021, we surveyed 503 hunters throughout the state of Texas, USA, and 481 Texas landowners who owned property in CWD-affected counties to better …

Evaluating Population Genetic Structure And Potential Genomic Signals Of Natural Selection In A Migratory Songbird (Protonotaria Citrea), Tyler A. Hohenstein

Theses and Dissertations

In this study I attempted to further resolve the population genetic structure in the Prothonotary Warbler (Protonotaria citrea), and conducted an outlier SNP analysis and exploratory gene ontology analysis to investigate potential ongoing natural selection in the species. This analysis of population structure confirms previous work by DeSaix et al. (2019), where weak population structure was observed between eastern sites along the Atlantic Coastal Plain, and western sites in the Mississippi Alluvial Valley, possibly due to a genetic discontinuity across the Appalachian Mountains. I conducted two forms of outlier SNP analyses, a principal component analysis (PCA)-based approach to identify SNPs …
