The Farm As Place In A Changing Climate: Capturing Women Farmers' Experiences In Idaho, United States And Victoria, Australia, Tagen Towsley Baker
The Farm As Place In A Changing Climate: Capturing Women Farmers' Experiences In Idaho, United States And Victoria, Australia, Tagen Towsley Baker
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In Australia and the US, women play a vital role in the agricultural sector. However, historically farmwomen’s contributions to agriculture as well as their individual knowledge and social resilience to stressors like climate and climate change have been unrecognized and rendered invisible. Drawing on interdisciplinary scholarship from geography and the humanities, this dissertation explores the farm as place in a changing climate, drawing on women farmers’ experiences, under three distinct themes: identity, place, and photography. The dissertation research includes three distinct parts. First, incorporating non-fiction writing and photography, I explore my agricultural and religious heritage, as well as familial connections …
Evidence Of Variable Climate And Resources During The Late Pleistocene And Holocene At Gona, Ethiopia, Marie White
Evidence Of Variable Climate And Resources During The Late Pleistocene And Holocene At Gona, Ethiopia, Marie White
Steeplechase: An ORCA Student Journal
The African Humid Period (AHP) spanned a period of approximately 15 to 5 thousand years ago (ka) and resulted in Northern and Eastern Africa being wetter than today. This climate change event impacted flora, fauna, and humans to an unknown extent. Much of the work on the AHP across Eastern Africa utilizes lacustrine and marine proxies rather than river-based (fluvial). Gona, located in the Afar region of Ethiopia, is known for its extensive archaeological and fossil records in fluvial deposits. However, the paleoenvironment of the AHP at Gona has not been investigated. This study uses stratigraphy, geochronology, and paleopedology to …

Improving Thorium-230 Determination In Marine Sediment, Katherine Mateos
Improving Thorium-230 Determination In Marine Sediment, Katherine Mateos
Independent Study Project (ISP) Collection
Our oceans are intimately related to the climate of our planet. Paleoceanographic approaches aim to study oceans through geologic time to improve models of future climate. Radioisotopes provide us with chemical tracers that help us understand change through time. The uraniumseries decay chain contains thorium-230, a decay product of uranium-234. This isotope is useful to paleoceanographers in its disequilibrium to its parent isotope and in determining the flux of sediment falling to the ocean floor. In order to use 230Th to study oceans, we must be able to accurately measure the amount of thorium in sediment samples. Thorium is found …

Water And War: The Potential For Perpetuation Of Conflict Due To Climate Change, Kaufman Butler
Independent Study Project (ISP) Collection
Climate change has had a dramatic impact on the world’s weather for years, scientists can only make predictions about how global climate will continue to change going forward; but in all scenarios the circumstances are quite dire. The Middle East and North Africa (MENA) will see some of the most severe effects of climate change, which will permanently alter the lives of millions of people in the region. In the MENA region, climate change is projected to result in extreme drought and temperatures which will lead to increased water scarcity, in what is already the most water poor region in …

Modeling Extreme Heat Events Using Global Reanalysis Data: An Assessment Of Current Climate Data And The Need For Improved Weather Station Data In Tennessee, John Reasons
Electronic Theses and Dissertations
Wet Bulb Globe Temperature (WBGT) is used to assess categorical heat stress risk factors for individuals working in outdoor environments and to provide guidelines for work/rest ratios and water intake. The variables required to compute WBGT are used by meteorologists for many purposes and are available through the Copernicus Program which was implemented by European Centre for Medium-Range Weather Forecasts (ECMWF) to provide users access to ECMWF Re-Analysis (ERA) historical database. WBGT values for Tennessee during National Weather Service (NWS) issued excessive heat warnings were calculated to determine the need for additional advisories based on WBGT guidelines. Monthly average WBGT …

Changes In Mammalian Abundance Through The Eocene-Oligocene Climate Transition In The White River Group Of Nebraska, Usa, Robert Gillham
Changes In Mammalian Abundance Through The Eocene-Oligocene Climate Transition In The White River Group Of Nebraska, Usa, Robert Gillham
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Marine records show major cooling during the Eocene-Oligocene Climate Transition (EOCT). Most proxy studies in the White River Group suggest drying across the EOCT, and some suggest cooling. The lower resolution continental record has hindered a direct correlation of the marine climate record to Nebraska. I explore various correlation schemes and what they imply for faunal changes. This study compiles and analyzes data from 4,875 specimens in the University of Nebraska State Museum (UNSM) collection to test the hypothesis that climate change across the Eocene-Oligocene (E-O) boundary caused significant abundance changes in mammals. A series of binning schemes was created. …
Evaluating Future Reservoir Storage In The Rio Grande Using Normalized Climate Projections And A Water Balance Model, Nolan T. Townsend
Evaluating Future Reservoir Storage In The Rio Grande Using Normalized Climate Projections And A Water Balance Model, Nolan T. Townsend
Earth and Planetary Sciences ETDs
We develop and implement new tools for assessing the future of surface water supplies in downstream reaches of the Rio Grande, for which Elephant Butte Reservoir is the major storage reservoir. First, a normalization procedure is developed to adjust natural Rio Grande streamflows simulated by dynamical models in downstream reaches. The normalization accounts for upstream anthropogenic impairments to flow that are not considered in the model, thereby yielding downstream flows closer to observed values and more appropriate for use in assessments of future flows in downstream reaches. The normalization is applied to assess the potential effects of climate change on …

The Urban Infrastructure For Sustainability: Learning From Kigali, Marwan Ghandour
The Urban Infrastructure For Sustainability: Learning From Kigali, Marwan Ghandour
Marwan Ghandour
Until 2013, when a new master plan for the city was approved, Kigali had very few urban regulations in place. Incremental constructions, usually associated with informal urbanization, were the norm rather than the exception. Most of the city fabric grew organically creating a unique configuration of urban adjacencies, which would be improbable for planners and designers to imagine. This configuration is particular to the geographic, economic and social conditions of the city as incremental urbanization slowly adjusted to the living conditions, through the actions of thousands of city residents over a long period of time. These actions were formed in …

The Role Of The Southern Ocean On Global Ocean Circulation And Climate, Brady Scott Ferster
The Role Of The Southern Ocean On Global Ocean Circulation And Climate, Brady Scott Ferster
Theses and Dissertations
The Southern Ocean (SO) is a unique and highly dynamic region with strong temperature and salinity gradients. A comparison between satellite-derived salinity and observations indicates strong differences along coastal boundaries, areas of low temperature, and regions of strong currents. Although differences throughout much of the SO are shown to be negligible, resolution and smoothing in the products create large biases in horizontal gradients and errors in estimating the water cycle. The three-dimensional movement of water within the SO plays an important role in the global Meridional Overturning Circulation (MOC), where the Southern Hemisphere westerlies drive both zonal and meridional transports …
Hourly Precipitation Climatology Of The Southeast United States, Vincent Brown
Hourly Precipitation Climatology Of The Southeast United States, Vincent Brown
LSU Doctoral Dissertations
Precipitation changes are one of the most important potential outcomes of a warming climate because of how essential it is to society and ecosystems. Sub-daily precipitation time series provide more information on precipitation characteristics, particularly frequency, intensity, and duration compared to daily data. In a series of four peer-reviewed manuscripts, this research investigates sub-daily precipitation characteristics from a climatological perspective. The first study introduces a climatology of hourly precipitation for four first-order weather stations across Louisiana, explores possible changes in the hourly precipitation distribution, and links winter Gulf of Mexico sea surface temperatures to the frequency of hours with precipitation. …

United States Department of Agriculture Wildlife Services: Staff Publications
Understanding the distribution of biodiversity across the Earth is one of the most challenging questions in biology. Much research has been directed at explaining the species latitudinal pattern showing that communities are richer in tropical areas; however, despite decades of research, a general consensus has not yet emerged. In addition, global biodiversity patterns are being rapidly altered by human activities. Here, we aim to describe large‐scale patterns of species richness and diversity in terrestrial vertebrate scavenger (carrion‐consuming) assemblages, which provide key ecosystem functions and services. We used a worldwide dataset comprising 43 sites, where vertebrate scavenger assemblages were identified using …

Past, Present, And Future Arctic Climate And National/Community Risk Assessment, Jeff Auger
Past, Present, And Future Arctic Climate And National/Community Risk Assessment, Jeff Auger
Electronic Theses and Dissertations
The Arctic is warming at a rate nearly double that of the global average. The enhanced rate of warming impacts weather and climate across the Northern Hemisphere. As the meridional (south to north) thermal gradient weakens, the middle-latitude westerlies are expected to slow and become “wavier” increasing heat and moisture advection to higher latitudes. A quasi-stationary ridge-trough system of the jet stream increases chances for droughts, floods, heatwaves, and cold spells. These impacts have already been observed as North American forest fires and early or extended Great Lake ice out. It is more important than ever to understand how the …
