Trends Of Autumn Phenology In Response To Environmental And Meteorological Variables, Meagan Renee Maguire

Masters Theses

Previous studies have identified that changes in plant phenology are most likely induced by climate variability. One such change is the end of season (EOS) for deciduous forests in the United States. In essence, the EOS represents the end of plant productivity for a given year; the phase in which plant dormancy is reached. However, our wealth of knowledge on plant phenology largely overlooks the phases that occur in autumn, especially the EOS, with many previous studies focusing on spring phenology. This study uses remote sensing MODIS aerial imagery data and historical meteorological data to analyze any relationships that may …

However there is no baseline record of the climate mitigation currently performed by the trees on Pomona’s campus through carbon storage. This study seeks to determine a current baseline quantity of carbon stored and sequestrated by Pomona’s trees as well as possible courses of climate mitigation for Pomona College to take. Initial information gathering was conducted through interviews with several stakeholders. This study was conducted using data collected prior to …

Species Data And Vector Modeling: Evaluating Datasets For Improved Models Of Ixodes Ricinus Tick Distribution In Europe Under A Changing Climate, Steven Jones

Electronic Theses and Dissertations

To increase capacity for monitoring and surveillance of tick-borne diseases, publicly available tick distribution and climate change datasets are required to create accurate predictive distribution models. It is difficult, however, to assess model accuracy and utility when using incomplete datasets.  The more recent development of comprehensive tick databases for Europe and availability of climate change scenarios from multiple IPCC Assessment Reports allows for improved modeling efforts. Multiple tick datasets were combined and three climate change projections were compared by predicting current and future distributions of Ixodes ricinus ticks in Europe using the MaxEnt species distribution model. Overall, much of Europe …

Estimation Of Economic Risk From Coastal Natural Hazards In Louisiana, Rubayet Bin Mostafiz

LSU Doctoral Dissertations

Louisiana, U.S.A., is among the most vulnerable areas globally to coastal natural hazards, with risk vulnerability likely increasing. The risks associated with non-tropical-cyclone hazards in Louisiana’s coastal zone have been understudied. This research enhances present and future (i.e., 2050) Louisiana risk assessment using locally-weighted, model-based hazard frequency/intensity and population projections.

Results suggest that property risks associated with extreme cold temperature and tornado are and will remain costlier than those for hail and lightning. Property risks of extreme cold temperature and hail are projected to decrease with the expected warming temperatures, with those of all four of these hazards peaking in …

Creative Common Worlding With Research Creation In Early Childhood Education, Sarah M. Hennessy

Electronic Thesis and Dissertation Repository

Creative Common worlding with research-creation in early childhood education engages with provocations that disrupt dominant understandings of children and their relations with more-than-human and human others. Reconceptualizing alternatives through art, this dissertation contemplates the potent possibilities beyond human stewardship, underscores the influence of an uncommoning lens, and emphasizes the difficulties with humancentric notions of research. If, by disrupting how we understand ourselves and our role in place, we modify our actions and change our habits, then perhaps we can live differently and contribute differently to the planet. Through a common worlds framework together with research-creation, this dissertation considers climate education …

The Global Impact Of The Antarctic Ice Sheet In A Warming World: Using Numerical Modeling And Critical Physical Geography To Assess Climate Change, Sea Level Rise, And Climate Justice

Doctoral Dissertations

Anthropogenic climate change is causing disruptions in the Earth system with negative ramifications for life on our planet. Increasing atmospheric greenhouse gas concentrations lead to accumulated heat content and the cryosphere is one of the earliest places to show changes in response to rising temperatures. The melting of the Antarctic Ice Sheet will have myriad effects on global climate due to interconnections and feedbacks between the ice sheet, ocean, and atmosphere. In this dissertation I use numerical modeling and critical geography to assess future climate conditions that occur in response to changes in Antarctic Ice Sheet melt as well as …

Examining The Impacts Of Flooding On Public Health, Lauren Gibson

These types of repeated major events have the potential to significantly impact people’s lives and livelihoods. When looking at the issue from a public health perspective, it is known that natural disasters such as flooding can negatively affect community health. However, little research has been done to analyze the impacts on individual health from flooding. This issue inspired a more in-depth research analysis to examine those health impacts from local Horry County residents. This research aims to …

Capital City Ventures Towards An Equitable Clean Energy Transition: A Case Study Comparison Between Columbia, South Carolina And Richmond, Virginia, Claire Windsor

Senior Theses

Combatting climate change requires a rapid transition to renewable sources for energy generation. In the United States, the electricity sector alone accounts for 28% of greenhouse gas emissions (28%), with about 63% of electricity generation derived from burning of fossil fuels (EPA, 2020). In order to lower greenhouse emissions from the energy sector, federal, state, and local policies must pave the way for renewable energy and energy efficiency innovations and policies. However, political action to address the effects and combat the causes of climate change have been limited due to political gridlock at the federal level. In addition, under neoliberalism, …

Fire Emissions In The Tropical Indonesia: Improved Estimation And Driving Forces Investigation, Xiaoman Lu

Electronic Theses and Dissertations

Indonesia has experienced frequent fires since the 1970s due to large-scale peatland conversion and extensive drainage for agricultural development. Fire emissions released from these fires have led to Indonesia being the world’s 3rd largest emitter of greenhouse gases in certain years. Given that fire emissions severely affect climate, weather, and the human environment, numerous approaches have been developed to estimate fire emissions. However, existing emission estimates differ largely by a factor of four in this tropical country because of frequent cloud interferences and low-temperature smoldering fires. Therefore, this dissertation aims to improve the quantification of Indonesian fire emissions through enhanced …

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 …

Climate Change Vulnerability And Perceived Resilience Among Smallholder Farmers In The Upper West Region Of Ghana, Evans Sumabe Batung

Electronic Thesis and Dissertation Repository

Globally, observed climate change has become a major barrier to agricultural productivity. At the same time, present and projected climate impacts are disproportionately affecting smallholder farmers in sub-Saharan Africa (SSA) where smallholder agriculture constitutes the predominant source of livelihood. Due to the vast agricultural potential of SSA, climate change resilience has been central in several multi-level deliberations over the past few decades. However, existing policies aimed at improving the effects of climate change on food security have overwhelmingly focused on the climatic dimensions of vulnerability, resulting in a lack of knowledge of the role non-climatic factors also play in shaping …

Impacts Of Climate Change On Food Security And Smallholder Livelihoods In Northern Ghana, Kamaldeen Mohammed

Electronic Thesis and Dissertation Repository

Climate change and food insecurity threaten the livelihoods of smallholder communities in the Global South. In the Ghanaian context, climate change and food insecurity are particularly crucial challenges in the northern regions, where most people are engaged in diverse activities in the agricultural sector. Despite tremendous efforts to curtail food insecurity and climate change vulnerability of smallholder households in northern Ghana, food insecurity and climate change remain pervasive in the region, indicating that smallholder adaptive capacities and resilience to the impacts of climate change are not commensurate with the severity of the problems. Emerging literature has indicated that livelihood diversification …

Composite Analysis Of Mendenhall Glacier Interannual Glacial Health Decline, Hailey Marie Cantrell

Masters Theses

Glacial health in Alaska, USA is demonstrating an interannual declining trend. Repetitive years have suffered an imbalance between winter seasonal ice accumulation and summer seasonal ice loss. Increased ice loss has commonly been attributed to warmer Arctic summer temperatures, which contribute to greater calving events and amplified ablation. Study of the unique climatic influences by different variables is ongoing and at the forefront of climate-glacier interaction research.

This study is designed to quantitatively evaluate correlations between changes in Alaskan climatic patterns and an interannual trend of declining glacial health for Mendenhall Glacier by combining analysis of Landsat satellite imagery, teleconnection …

International Migration From The Latin American-Caribbean Region: Taking Environmental Indicators Into Consideration, Chelsea Wepy

Student Theses and Dissertations

International migration, the act of leaving one’s country to permanently settle in another country, is driven by many socio economic/political factors, such as lack of economic opportunity, access to education, governmental corruption, and violence. These factors have proven to be the reason that many citizens within the Latin American-Caribbean region either choose or are forced to relocate internationally. While these factors are important to consider independently; these issues are often exacerbated by changes in the natural environment. The objective of my paper is to highlight the importance of considering changes in the natural environment. In doing so, I hope to …

A location-specific evaluation of hydrological landscape responses concerning past and projected climate and land use land cover (LULC) changes can provide a powerful intellectual basis for developing efficient and profitable agroecosystems, and overcoming uncertain and detrimental consequences of LULC and climate shifts. This dissertation assessed the impacts of land use, management, and climate change on water resources in the Missouri River Basin (MRB) through four specific studies that included: (i) to study the responses of leached nutrient concentrations and soil health to winter rye cover crop (CC) under no-till corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] rotation, (ii) to …

Ground Warming Leads To Changes In Carbon Cycling In Northern Fen Peatlands: Implications For Carbon Storage, Ericka James

Electronic Thesis and Dissertation Repository

Northern peatlands store one third of the world’s soil carbon (C), as they remove more C from the atmosphere via photosynthesis than they release to the atmosphere through ecosystem respiration and methane (CH₄) production. Climate change threatens this function by stimulating C release from peatland stores as peat temperatures warm and soil moisture is reduced. Ground heating of +4 °C above ambient peat temperatures was initiated in a Sphagnum moss-dominated, nutrient poor fen and a Carex sedge-dominated, intermediate nutrient fen. Over one growing season, Carex fen heated plots had increases in photosynthesis (+23%), ecosystem respiration (+22%), and CH …

Electric Grid Decarbonization Pathways: Landscape Impacts, Policy Interactions, And The Need For Cooperation, Austin Wesley Thomas

Graduate College Dissertations and Theses

Climate change has motivated governments around the world to ratify aggressive greenhouse gas emissions reduction targets. Meeting these targets will require improved energy efficiency, behavior changes, and energy system decarbonization. Many climate change and energy policy targets imply the deployment of large amounts of low carbon, renewable energy resources like wind turbines and solar photovoltaic (PV) panels but do not specify how these resources will be sited on the landscape. The relationships between weather conditions, terrain, land cover, existing electric grid infrastructure, and electricity consumers will govern how these wind and solar PV infrastructure configurations develop and how quickly they …

A Formative Assessment Of The Vulnerability Context Of Three Indigenous Communities In Rural Ecuador For Improved Intervention Design, Ivy Blackmore

Arts & Sciences Electronic Theses and Dissertations

Nearly 20 % of the current world population are small-scale producers living in rural areas who rely on agriculture and related activities to support their families (IFAD, 2016; World Bank, 2008). Despite the almost 76 billion USD of official development assistance committed to agriculture improvement projects and associated activities over the past decade, many of the intended beneficiaries remain poor and struggle to meet their basic needs. The lack of success in addressing rural poverty highlights the need for quality research focused on understanding what type of intervention/s could help rural communities sustainably improve their livelihood security.

The goal of …

Graduate Student Theses, Dissertations, & Professional Papers

This study used in-depth interviews of permanent residents on Grand Isle, Louisiana, a remote barrier island, to better understand their perceptions of structural flood measures, non-structural responses to flooding and hurricanes, and perceptions of vulnerability to flooding, hurricanes, and climate change on a remote barrier island-Grand Isle, Louisiana. Residents' perceptions regarding the various structural measures implemented by the federal, state, and local government appeared mixed. Non-structural responses to flooding risks implemented at the household, community, state, and federal level continue to strengthen resiliency on Grand Isle. According to interviewees, aspects of environmental, rural, and economic vulnerability on Grand Isle impact …

We Refugees, Again, Aaron Linas

Dissertations, Theses, and Capstone Projects

Dramatic shifts in climate have generated a new form of global displacement. These ‘climate migrants’ challenge the notion of state sovereignty by introducing a new paradigm for global responsibility. I seek to address this emerging demand of sovereignty by outlining the normative mechanisms of state institutions when encountering displaced persons. The extreme cases of disappearing island nations creates stateless population incompatible with standard liberal values of humanitarianism and border security. My claim is that current normative institutions and principles of assistance to migrating people are insufficient to manage the international crisis of climate change. To be able to aid migrants …

Living With Loss In The Anthropocene, Jaynetha Robinson

MAIS Projects and Theses

Heatedly contested at various points in its development, climate change discourse is at once a political and social issue, an environmental and ecological issue, and a physical and mental health issue. Less attention has been paid to the latter. During her work with the terminally ill, Kübler-Ross (2005) outlined 5 stages of grief: anger, denial, bargaining, depression, and acceptance. That outline is now seen as analogous to the feelings that we may have towards issues of climate change, e.g., the real and perceived loss of ecosystem services, as well as uncertainty in regard to the future of humanity. With that …
