Solar-Powered Microgrids In Northern California: An Opportunity For Resilience, Marina Riddle

Master's Projects and Capstones

Planned and unplanned power outages have been increasing in frequency and duration, negatively impacting all public sectors, and threatening public safety. These outages are deadly to those who rely on medical devices. As climate change-fueled extreme weather events (wildfires, earthquakes, storms, etc.) also increase in frequency, our electrical grid must be prepared to bounce back. Microgrids provide necessary redundancy and reliability. Through a novel GIS suitability analysis, based on solar radiation, land use type, local energy demand, distance to transmission lines, distance to roads, and slope, optimal locations for solar-powered microgrids throughout Northern California were determined. The counties of Fresno, …

Benthic Community Dynamics And Stony Coral Demographics In Florida In Relation To Acute Disturbances And Chronic Pressures, Nicholas P. Jones

All HCAS Student Capstones, Theses, and Dissertations

The persistence of coral reef communities is threatened by a suite of pressures operating at varying spatial and temporal scales. In general, acute disturbances (short term stochastic events such as marine heatwaves or hurricanes) and chronic pressures, such as ocean warming, have caused the most significant changes to stony coral assemblages (order Scleractinia) and continue to impair recovery potential. Additionally, many coral reefs are subject to local chronic anthropogenic pressures resulting in poor water quality or sedimentation, which further impact stony corals and shape benthic community structure, particularly near urbanized coastlines. For the viability of communities on coral reefs, a …

Assessing The Efficacy Of California’S Wildfire And Forest Resilience Action Plan, Chloe Nelson

Master's Projects and Capstones

California’s wildfire threat eclipses current forestry management and wildfire mitigation strategies in place to protect people, infrastructure, and the natural environment. Climate change escalates wildfire risks with declining water supply coupled with hotter, drier conditions. California’s Wildfire and Forest Resilience Action Plan attempts to integrate and build upon previously successful wildfire resilience plans to amplify the scale and pace of the state’s land management and community protections. This research assesses the plan’s efficacy to respond to the growing wildfire threat. This study investigates if there is equitable planning for the needs of high-wildfire risk groups living in the WUI and …

Connecting Communities To Coastal Resilience: Enhancing Sustainability Through Public Participation In Salt Marsh Management And Restoration In Suffolk County, Ny, Jennifer L. Mcgivern

Dissertations, Theses, and Capstone Projects

Coastal resiliency is becoming significantly more critical to the livelihood of coastal communities as the frequency and intensity of storm events increases and is exacerbated by rising sea levels due to climate change. In October 2012 Superstorm Sandy impacted the New York-New Jersey area costing over $70 billion in storm damages and 147 lives lost, as storm surges surpassed record highs for the region. Protruding more than 100 miles into the Atlantic Ocean with over 1,000 miles of shoreline, Long Island is particularly vulnerable to the increasingly ferocious and numerous storms as well as the rising sea levels that climate …

Learning From The Seed: Illuminating Black Girlhood In Sustainable Living Paradigms, Toni Powell Powell Young

USF Tampa Graduate Theses and Dissertations

The contemporary image of sustainable living presents a culturally narrow view of its participants and the manner of engaging in sustainable living paradigms. Through crystallization (Ellingson, 2009) I present a mixed methods approach that emphasizes participant observation, visual, mediated, and discursive analyses, as well as demonstrates the efficacy of Culture Centered Black Feminist Auto/Ethnography. This project seeks to highlight and place within historical context, the ways in which African American girls, who are largely left out of the prevailing image of sustainability, perform and articulate sustainability for themselves, in their homes, and throughout their home communities.

In their everyday lives, …

The Role Of Vegetative Cover In Enhancing Resilience To Climate Change And Improving Public Health, Anastasia D. Ivanova

Masters Theses

Changing temperature and precipitation patterns are causing degraded soil, water, and air quality which is negatively affecting the safety and health of people, and the productivity of urban and rural communities. However, research shows that implementing urban forests and cover crops into urban and rural landscapes, respectively, can mitigate these effects by providing ecosystem services. As extreme precipitation and heat events continue to intensify, there is a need for comprehensively assessing these ecosystem services under changing climates and for this information to be easily accessible by communities for rapid land-use decision making. Therefore, I investigated the role of urban forests …

Climate Change And Sustainable Development Within The Tourism Sector Of Small Island Developing States: A Case Study For The Bahamas, Arsum Pathak

USF Tampa Graduate Theses and Dissertations

The research literature suggests Small Island Developing States (SIDS) are vulnerable to climate change. Tourism in SIDS is sensitive to climate variations and dependence of the sector on natural resources (beaches, coral reefs) adds to their vulnerability. The purpose of this study is to assess climate impacts and adaptation within the tourism sector of a SIDS – The Bahamas that relies on tourism and faces climate vulnerabilities, as do other SIDS. Given the importance of tourism to their sustainable development by supporting economic growth and employment, this study identifies timely risks and adaptation planning for a tourism-based SIDS economy in …

Assessing Resilience To Flooding And Human Wildlife Conflict In Developing Countries : A Case Study Of Flood Related Trauma And Human Wildlife Conflict In Nepal, Gita Bhushal Adhikary

Theses, Dissertations and Culminating Projects

Developing countries have a large population that is dependent on farming and agriculture, making them more heavily reliant on natural resources like forest and water. Nepal is one of such countries, with a unique geography where much of the population lives in close proximity to conservation areas and water bodies. Due to these natural features and increased environmental pressures such as extreme storms and deforestation, many of these communities have experienced loss, ranging from property damage to human injury or death because of the related extreme flooding and increased humanwildlife conflict. These challenges are amplified in Nepal due to the …

Marine Protected Areas In Areas Beyond National Jurisdiction: Defining "Success" For Conservation And Management, Emily Suzanne Nocito

Electronic Theses and Dissertations

With growing attention to and use of marine protected areas [MPAs], there are an increasing number of policy goals ascribed to these area-based management tools [ABMT]. One expectation is that an MPA can increase system “resilience”, yet oftentimes resilience – including whether we are considering social, economic or ecological resilience – stays unspecified. In recent years, there has also been a specific focus on MPAs as tools to promote climate change resilient ocean systems. Through a meta-analysis of the scientific literature and an analysis of over one thousand three hundred voluntary commitments made at the United Nation Ocean Conference, this …

Weathering Climate Change: Provisions For Climate Change Resiliency In Transboundary River Treaties, Emily Joan Zmak

Electronic Theses and Dissertations

Climate change will be most apparent in alterations to the hydrologic system - shifts in movement, variations in extremes - thereby defining many resource disputes in the coming decades. Water is a boundaryless resource; as its hydrologic patterns shift within and without borders, so too will preexisting agreements on its use and allocation. The question for transboundary water agreements is: how can agreements both satisfy parties' needs and account for future uncertainties of climate-induced changes to their basins' hydrologic systems?

From examining literature and water agreements, this thesis develops a list of provisions identified as foundational to resiliency in transboundary …

Operationalizing Resilience In The Face Of Water Conflict: Linking Social And Ecological Systems, Stephen Andrew Mcguire

Theses and Dissertations

This dissertation investigates the possibility of linked surface-groundwater governance through the application of a social-ecological systems lens to the Lake Beulah Conflict over a high capacity well in Walworth County, Wisconsin. Potential adverse impacts the loss of Ca2+ rich groundwater would have on Lake Beulah’s water quality was modeled through an ex-ante assessment method using the U.S. Army Corps of Engineers lake and reservoir model BATHTUB, the U.S. Geological Survey geochemical model PHREEQC and a Ca2+ mass balance equation. The utility of this information in a management setting was also analyzed. Reduction of Ca2+ through groundwater withdrawal revealed a eutrophication …

A Complex Systems Simulation Study For Increasing Adaptive-Capacity, Kadambari Ram

Walden Dissertations and Doctoral Studies

Examination of empirical research confirmed that climate change is a complex problem of anthropological origin and revealed the need for a management framework to facilitate strategic decisions aimed at mitigating a rise in global temperatures of 2-°C linked to irresponsible and unsustainable business practices. The purpose of this simulation study was to develop a management framework of resilience, robustness, sustainability, and adaptive-capacity (RRSA) for organizations viewed as complex systems to address the current unsustainable state. As such, the evolutionary-RRSA prisoner's dilemma (PD) simulation was developed using an evolutionary game theory approach to agent based modeling and simulation, to generate data. …

Dune restoration is a common method of increasing coastal resilience. A dune restoration program was initiated by the City of South Padre Island, TX in 2010 consisting primarily of plantings of Sea Oats, Uniola paniculata, and Bitter Panicum, Panicum amarum and has continued approximately annually thereafter. These restoration efforts were evaluated in this study by comparing dune ecological structure and function among reference sites and restoration plots ranging in age from 2 to 5 years. Plant and animal communities were examined using a combination of quadrat sampling, funnel traps, pit-falls and sweep nets. Soil organic content and soil electric …

Preserving Biodiversity For A Climate Change Future: A Resilience Assessment Of Three Bay Area Species--Adenostoma Fasciculatum (Chamise), Arctostaphylos Canescens (Hoary Manzanita), And Arctostaphylos Virgata (Marin Manzanita), Alison S. Pollack

Master's Projects and Capstones

Anthropogenic climate change is an undeniable threat to the future of the natural world and human civilization. These shifts will have profound impacts on vegetation, especially for species endemic to isolated regions or sensitive to climate change factors. However, species resilience can predict success into the next century. Resilience is defined as the ability to withstand climate change factors, whereas vulnerability is defined as susceptibility to climate induced stress or damage.

Chaparral and coastal scrub ecosystems within the Bay Area of California provide a unique context for examining resilience, as many species are adapted to high temperatures, drought, and wildfire—all …

Coral Genotype Influence On Growth And Stress Resistance In Acropora Cervicornis: Investigating Potential Energy Tradeoffs, Peter T. Grasso

HCNSO Student Theses and Dissertations

Over the last few decades coral reefs have faced unprecedented declines in health due to natural and anthropogenic sources. Until recently few studies have examined genotypic variation of growth and thermal stress resistance in Acropora cervicornis. This study aims to assess the potential for energy trade-offs between growth and thermal stress resistance by following 120 coral fragments from 12 genotypes of Acropora cervicornis over the course of 15 months to determine average growth rates for each genotype. Following the completion of the growth observation a bleaching event occurred in the lower Florida Keys providing the opportunity for examining thermal …

Effects Of Gender And Spirituality On Adults' Resilience To Daily Non-Traumatic Stressors, Lois S. Harris

Walden Dissertations and Doctoral Studies

Researchers have conducted several studies of spirituality as it relates to individuals' coping strategies and resilience when facing life trauma. There is less research, however, on spirituality as it relates to adults' resiliency to daily non-traumatic stressors. The purposes of the current study were to examine the relationship between spirituality and adults' resilience to daily, non-traumatic stressors and assess whether gender has a moderating effect on this relationship. A quantitative correlational study based on Lazarus's transactional model of stress and coping using convenience sampling, an online survey (N= 94) was administered. Of the 94 participants ages 19 to 68, 66 …

Ecodistricts In San Francisco: The Implementation Of Neighborhood Regional Planning And Its Potential Effects On Environmental Resilience, Elizabeth M. Juvera

Master's Projects and Capstones

Ecodistricts, or neighborhood-scale, community-driven areas of sustainable development, have emerged internationally and within the U.S. to create models of adaptive environmental design and advanced urban infrastructure. Central SoMa is the first ecodistrict to be planned and implemented in San Francisco, with the intention of revitalizing and greening this urbanized region of the city. At this time, the Central SoMa area has very low biodiversity levels, inefficient infrastructure, and poor water management capabilities. Through the implementation of ecodistricts in San Francisco, the city can integrate physical and behavioral sustainability measures from existing ecodistricts such as permeable surfaces, green roofs, stormwater management, …

Relationships, Knowledge, And Resilience: A Comparative Study Of Stakeholder Participation In Great Lakes Areas Of Concern, Kathleen Colin Williams

Theses and Dissertations

This dissertation investigates the current practices of environmental governance in the Great Lakes region, where at one time the rivers that fed the Great Lakes were choked with debris and on fire. The Great Lakes Water Quality Agreement of 1978 and the 1987 updates inspired collective action to remediate and restore the rivers and nearshore zones of the lakes through the implementation of an ecosystem approach, which included a public participation dimension. While funding and momentum has fluctuated, the constructs – Areas of Concern (AOC), Remedial Action Plans (RAP), and Public Advisory Councils (PAC) persist. In 2010, the Great Lakes …

Understanding Vulnerability In Alaska Fishing Communities: A Validation Methodology For Rapid Assessment Of Well-Being Indices, Conor M. Maguire

All Master's Theses

Social well-being indices measure how fishing communities are likely to be affected by social-ecological perturbations, and are a significant tool to identify the primary issues influencing communities’ sustained participation in fishing activities. In an attempt to further our understanding of how communities are affected by such perturbations, we have developed a rapid assessment methodology to test the external validity of a set of well-being indices that measure community vulnerability. This methodology informs how well such indices reflect the communities they represent by measuring elements of well-being through field observations, and comparing them to corresponding index components created from secondary data …

A Spatial Dynamic Model Of Population Changes In A Vulnerable Coastal Environment, Kenan Li

LSU Doctoral Dissertations

Achieving coastal sustainability in low-lying coastal areas is a great challenge. This study developed a spatial dynamic model to study the coupled natural-human responses in the form of population changes in the Lower Mississippi River Basin region. The goal was to identify the key social-economic factors (utility) and selected environmental factors (such as hazards damage, elevation, and subsidence rate) that affect population changes, as well as how population changes affect the local utility and the local environment reciprocally. The study area was partitioned into the “north’ and the “south” by a hypothetical boundary to test the differences of the emergence. …

This research uses qualitative ethnographic methods and a theoretical framework based on actor network theory to better understand how …

Resilient Environmental Governance: Protecting Changing Ecosystems Through Multilevel Governance, Casey Stevens

Open Access Dissertations

International governance is increasingly defined by multilevel governance; with short-term projects, transnational cooperation between different groups, and unclear institutional space. In this situation, a key issue is the resilience of governance arrangements or the ability of governance arrangements to respond to political and ecological shocks to the system. Using international biodiversity governance, this study explores the question: What social and political processes produce resilient governance?

This study argues that the key to understanding resilient governance is the network structure within and outside of the governance arrangement. Modular network structures are able to generate ideas from multiple sources, able to solve …

Clonal Diversity Of Quaking Aspen (Populus Tremuloides): How Multiple Clones May Add To Theresilience And Persistence Of This Forest Type, Richard Scott Gardner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aspen forests and woodlands are widespread across the western United States and are a primary component of many ecosystems in the west. Aspen is a clonal species, with reproduction occurring both by root sprouting (suckering) and seeding. Traditionally, western aspen forests were thought to consist almost entirely of large clones established several thousands of years ago, with seeding events being rare and ecologically negligible. Although clones in the western US can grow to be many acres, recent studies have demonstrated a far greater proportion of small clones than had been previously thought to exist. In this study I wanted to …

An Analysis Of The Influences On Household-Level Adaptations To Environmental Hazards, Tiia Maria Carraway

LSU Master's Theses

Utilizing a randomized phone survey of coastal Louisiana residents, this study will focus on identifying which influences from a resident’s exposure, socio-economic vulnerability and adaptive capacity are the best indicators of an individual’s resilience. Two binary logistic regression models were developed to test the associations of resident response to: 1) acute hazards via household emergency plan adoption and 2) chronic hazards represented by behavior modification in response to daily air quality reporting where adoption of these two risk-reducing behaviors are viewed as increased individual resilience. Bivariate correlation analysis found that a north – south grouping of coastal Louisiana was significantly …

An Analysis Of The Prevalence Of The West Nile Virus In Relation To Health Resilience Along The Gulf Of Mexico, Lillian Patricia Mata

LSU Master's Theses

As the Earth’s climate changes, coastal communities are increasingly vulnerable to the natural hazards that are driven by these processes, particularly in regards to the health of these communities. It has been shown that disease patterns can change in response to our environment, putting the health resilience of communities at risk. This study looks at the relationship between natural exposure and traditional resilience index variables in the context of the spread of West Nile Virus along the Gulf of Mexico. Through analysis of 534 counties, the West Nile Virus for 2001-2012 was analyzed as an incidence and incidence rate at …

Fish And Macroinvertebrate Assemblage Composition And Diversity At Revetted Banks In The Pearl River And The Response Of These Assemblages To A Paper Mill Effluent Spill, Jose Alexander Vazquez

LSU Master's Theses

The armoring of river banks with riprap can have detrimental effects on lotic ecosystems due to the subsequent alteration of hydrologic regimes; however, evidence suggests that riprap can also increase aquatic diversity in degraded systems. The goal of my study was to determine what impacts riprapped banks have on fish and macroinvertebrate assemblages in the Pearl River, which has a history of anthropogenic degradation. I collected fishes with an electrofishing boat from armored and natural banks at five regions during fall 2011, winter 2012, and summer 2012. I also collected macroinvertebrates with introduced substrates in fall 2011. Richness was analyzed …

Community Resilience To Coastal Hazards : An Analysis Of Two Geographical Scales In Louisiana, Chi Li

LSU Master's Theses

Quantifying resilience is difficulties due to the different definitions of resilience, the interchangeable uses with two other terms “vulnerability” and “adaptability”, as well as the lack of consensus on what indicators should be selected to quantifying resilience. This thesis research studied the community resilience in Louisiana by applying the Resilience Inference Measurement (RIM) model at two geographic levels: county level and zip code level. The RIM model accesses resilience by using three dimensions (exposure, damage, and recovery) and two abilities (vulnerability and adaptability). The types of coastal hazards included in this study were: coastal, flooding, hurricane/tropical storm, tornado, and severe …

Comprehensive Planning And Resilience: A Study Of Louisiana Parishes After Hurricane Katrina, Mary Paille

LSU Master's Theses

When hurricanes Katrina and Rita hit in 2005, widespread devastation was felt in over half of the parishes in the state. More than 200,000 homes were damaged and more than 1500 people lost their lives. During this transitionary period, communities were vulnerable and looked for rebuilding leadership. As part of a post-catastrophe resilience movement, the Louisiana Recovery Authority formulated a 50-year regional plan for recovering south Louisiana called Louisiana Speaks. This planning process opened up an opportunity to reach those communities that otherwise may not have considered planning or how it could help them prepare for future events. This places …

Temporal Changes In Quality Of Life And Environment In New Orleans After Hurricane Katrina, Danielle Johanna Larock

LSU Master's Theses

Understanding and assessing the spatial and temporal changes of quality of life and environment of a community is critical to its sustainable development, especially after a disaster strikes. This study explores an approach that integrates remote sensing with socioeconomic data to assess the temporal changes in quality of life and environment (QOL) using Orleans Parish as an example. Hurricane Katrina, which struck New Orleans in 2005, has had vast implications economically, socially, and environmentally for this city and the surrounding area. Empirically quantifying these concepts will help to rebuild the city more sustainably. This study investigated change in environmental quality …
