A Study Of The Impact And Mitigation Strategies For Community-Defined Historic Places At Immediate (Within Three Decades) Risk Of Sea Level Rise, Isaac Quaye

All Theses

The rising sea level casts formidable threats on community-based historic places within coastal communities. These community-defined historic places derive their meaning from local values and are more recognized within the local community. Unlike recognized iconic historic places, these resources are confronted with inadequate resources to address the impacts of punctuated climate events. This study investigates the imminent threats posed by sea level rise (SLR) to community-defined historic places within the next three decades (2025) and explores mitigation strategies proposed by stakeholders. The study used a GIS-based (enhanced bathtub model) to model the impact of coastal inundation on three historic places …

Transforming Grassland Conservation: Challenges And Opportunities Across Law, Policy, And Human Dimensions, Conor D. Barnes

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Great Plains social-ecological systems are facing growing pressure from complex, ‘wicked’ problems. Addressing these problems will require integrating ecological resilience and complex systems thinking concepts into our legal framework in order to better reflect the changing ecological reality of the Great Plains and promote flexibility and adaptability in the face of that change. In this dissertation, I examine how past and present policy priorities have affected social-ecological systems on the Great Plains, and how ecological resilience and complex systems thinking might be applied to grassland management policy. In Chapter 2, I examine the rapid progress made in the adoption of …

Remotely Sensed Early Warning Of Algal Blooms In An Eastern Nebraska Reservoir: A Comparison Of Temporal And Spatial Indicators, Mercy Kipenda

School of Natural Resources: Dissertations, Theses, and Student Research

Cyanobacterial harmful algal blooms (CyanoHABs) detrimentally affect human, animal, and ecosystem health. Remotely sensed early warning systems for cyanoHABs in inland lakes could contribute to more proactive water quality monitoring and help mitigate negative impacts. Advances in freely available remote sensing imagery, with finer spatial, temporal, and spectral resolutions, present new opportunities for the development and comparative analysis of methods to detect sudden deterioration in lake water quality. In this thesis, I compared and tested for temporal and spatial early warning signals of cyanoHABs in field-based and remotely sensed datasets from 2019 to 2023 in Pawnee Lake in southeast Nebraska, …

Assessing, Restoring, And Centering Social–Ecological Relationships For Advancing Social–Ecological Resilience In The Northern Great Plains Grasslands, Katia Pilar Carranza Bernal

School of Natural Resources: Dissertations, Theses, and Student Research

The Northern Great Plains grasslands are social-ecological systems that were shaped by evolutionary and Indigenous social-ecological relationships. European colonization disrupted many of these interactions, including the coupling of fire and grazing, and degraded social-ecological resilience, shifting these grasslands to a new state. For those reasons, my research focused on assessing, restoring, and centering evolutionary and Indigenous social-ecological relationships for advancing social-ecological resilience in the Northern Great Plains grasslands. I first performed a study in the Nebraska Sandhillls assessing the potential of patch-burn grazing to support grassland resilience by comparing its effects to those of rotational grazing. Through vegetation and bird …

Sensitivity Of Present And Future Seasonal Precipitation Over Central United States To The Representation Of Rocky Mountain Topography, Ranasinghe Disanayakalage Sherly Shelton Ranathunga

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Precipitation change across the Central United States (USA) is of great interest to the research community. Studies using global climate simulations suggest that the “100^th-Meridian”, which separates the “dry west” from the “moist east” will shift to the east as the climate responds to future emissions pathways. However, these simulations are run at relatively coarse resolutions, which do not accurately represent topography. Here, we perform regional simulations using the Weather Research and Forecasting (WRF) model to explore the sensitivity of present and future precipitation patterns across the central USA to the representation of the Rocky Mountains (RM). We …

Making Waves In The Snow World: Microwave Remote Sensing And Infrasound Interactions With Seasonal Snow, Zachary Marshall Hoppinen

Boise State University Theses and Dissertations

Snow has profound impacts on our globe, economies, and ecosystems serving as a vital reservoir for drinking and irrigation water, renewable hydroelectric power, and as a natural hazard. However, effectively monitoring snow and snow water equivalent (SWE) presents challenges due to interannual variability, with SWE fluctuating by over 500 mm between years and peak snowmelt timing varying up to a month. These challenges will be further exacerbated by the non-stationarity of these snow and avalanche patterns in a changing climate requiring new spatially and temporally expansive remote sensing.

In this dissertation, we explore the potential of two evolving remote sensing …

Paths Of Least Resistance: A Geospatial Analysis Of The Integration Of Mississippian Communities In The Northwest Arkansas Ozarks, Joseph Jilek

Anthropology Undergraduate Honors Theses

During the Mississippi period (ca. AD 1050-1500), native groups occupying bluff shelters in the Northwest Arkansas Ozarks constructed three similarly sized mound-and-plaza centers: Goforth-Saindon (3BE0245), Collins (3WA0001), and Huntsville (3MA0022). Similarities in size and number of mounds suggests none rose to a position of power over the other and each integrated a separate community. Previous research hypothesizes that communities in emergent complex societies such as these are best defined by those who you interact with regularly, with mound centers less than a day’s travel from each other likely integrating the same communities. This study uses least-cost analysis, generating likely travel …

Analyzing The Losses And Gains Of A Land Category: Insights From The Total Operating Characteristic, Thomas Mumuni Bilintoh, Robert Gilmore Pontius, Zhen Liu

Geography

This manuscript provides guidance concerning how to use the Total Operating Characteristic (TOC) when (1) analyzing change through time, (2) ranking a categorical independent variable, and (3) constraining the extent for a gaining category. The illustrative variable is the marsh land-cover category in the Plum Island Ecosystems of northeastern Massachusetts, USA. The data are an elevation map and maps showing the land categories of water, marsh, and upland in 1938, 1971, and 2013. There were losses and gains near the edge of the marsh between 1938 and 1972 and between 1972 and 2013. The TOC curves show that marsh gained …

A Comparison Of Maxent Models For Aedes Aegypti Species Distribution In South America Utilizing Different Bioclimatic And Environmental Variables, Matthew Beer

Electronic Theses and Dissertations

Aedes aegypti is the principal vector for dengue transmission across large areas of the world. Understanding where this critically important vector lives is paramount to preventing the continued expansion of dengue globally. Using 1981-2010 bioclimatic (bioclim) variables, as well as additional environmental variables and elevation data, multiple MaxEnt models were constructed for Ae. aegypti within the South American continent to identify ecologically important variables and areas of persistent high suitability. All models had acceptable AUC scores (> 0.70), indicating accurate model fitting.

Spaces Of Progress And The Challenge Of “Mindfulness” In A Postcolonial World, M. Satish Kumar

Midwest Social Sciences Journal

Progress implied both change and improvement in the colonial and postcolonial world. Such a concept of progress came to be enshrined in specific geographical places. The notions of development and underdevelopment in the postcolonial context thereafter supplanted this idea. Over time, while the structures of colonial domination dissolved, those of embedded regional inequalities came to be deeply entrenched, thereby urging for Thich Nhat Hanh’s approach to “mindfulness” in a “postcapitalist,” postcolonial world. The key question is whether postcolonialism has reached an impasse in its delivery and deployment of ideas across the widening gulf between the spaces of progress and stagnancy. …

Notes On The Future Possibilities Of Engaged Anthropological Research: Why Decolonizing Anthropology Needs Black Diasporic Feminist Theory And Methodologies, Meryleen Mena

Midwest Social Sciences Journal

While in the past decade there have been more ethnographic accounts that shed light on minoritized stories and demystify the specific challenges that women and femmes experience during their research, much is desired to prepare students and junior scholars from marginalized identities for fieldwork research. Reflecting on a moment of precarity in the context of pre-impeachment São Paulo, I explain why the integration of Black diasporic feminist thought, method, and praxis is critical to further decolonizing efforts in anthropology. Beyond reflection, this narrative calls for sustained politically active engagement to establish an anthropology of liberation.

The Decline Of Republican Democracy And Rise Of The Techno-Authoritarian State: Reading Dystopian Novels In Hindi Literature, Manindra Nath Thakur

Midwest Social Sciences Journal

In the past few decades, the nature of capitalism has changed fast as it has lost its philosophical justification based on the principle of the common good. There have been many avatars of the idea of the “common good”: “white man’s burden to civilize the world,” “welfarism,” and “neoliberal concept of freedom of choice.” Capitalism now seems to have moved in a new direction, however, and it has failed to produce any further philosophical justification for its existence as a mode of production despite generating unprecedented economic inequality. Consequently, there is a rising tension between capitalism and democracy in societies …

Identifying Watershed And Climatic Factors That Influence Headwater Streams In The San Bernardino National Forest - A Framework For Adaptive Management And Conservation, Christine Sue Seeger

Electronic Theses, Projects, and Dissertations

Headwater streams play a significant role in overall watershed condition. These streams are critical freshwater resources and are imperative for human and ecosystem health. Seasonal variability in climate patterns is becoming increasingly more common as the effects of climate change are studied. The phenomenon known as “weather whiplash,” prolonged periods of drought followed by a sudden increase in precipitation, creates additional challenges for human and ecosystem conditions. Factors adversely impacting headwater streams include climate change, drought, wildfires, and human influence. While climate change continues to be studied, little is known about how weather whiplash patterns affect headwater streams in Southern …

We're Swarming Again! Swarming, Collectivity, And Trope: The Case Of Extinction Rebellion, Tyler J. Behymer

Department of Communication Studies: Dissertations, Theses, and Student Research

This thesis explores the rhetoric of the eco-movement Extinction Rebellion, focusing on the use of swarming and nature tropes to mobilize collective action and revivify contemporary notions of collectivity. Drawing on rhetoric of social movement scholarship, cultural studies, and psychoanalysis, this essay theorizes swarming as a tropological economy that expands the conditions of propriety in the context of collectivity. Through an analysis of Extinction Rebellion’s discourse, this study demonstrates how the naturalization of swarming tropes works in various ways to rewild conventional political discourse, galvanize disruptive collective assembly, and challenge green neoliberalism.

Research Collection College of Integrative Studies

Global climate science needs to address a fundamental challenge: the mismatch between the scales of anthropogenic processes driving change and the resulting climate impacts. While projected climate changes and impacts are global in extent, the drivers of this change, and the exposure to its impacts, are concentrated in densely populated urban areas. Despite occupying only 1–3% of the land, urban areas are home to most of the world’s population and responsible for ~70% of current greenhouse gas emissions [1]. By 2050, an additional 2.5 billion people are expected to live in urban areas, with up to 90% of this growth …

Assessment In The Potential Of Sustainable Community Development, Syifa Hanifa, Djati Mardiatno, Dina Ruslanjari

Surface Urban Cool Island Assessment In Village-Level Tourism Destinations Using Gis And Principal Component Analysis, Revi Hernina, Arif Wicaksono

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

This study describes the process to generate classification of village-level tourism destinations known as kampung tematik in Bogor Municipality based on values from Surface Urban Cool Island (SUCI), Normalized Difference Built-up Index (NDBI) ≤ -0.17, Normalized Difference Vegetation Index (NDVI) > 0.3, and Urban Index (UI) < -0.2. SUCI values represent the cool temperature, while NDBI ≤ -0.17, NDVI > 0.3, and UI < -0.2 are associated with dense and healthy vegetation. Herein, Band 10 from Landsat 8 was processed to generate land surface temperature (LST) and further, SUCI image was derived from LST image by employing SUCI algorithm. All three variables, namely NDVI, NDBI, and UI were also processed from Landsat 8 with date 24 May 2020. These four variables of SUCI, NDVI, NDBI, and UI image pixels were superimposed with 39 kampung tematik locations using Geographic Information System (GIS) which resulted in 14 locations containing the area percentage from four variables. The values from four variables in 14 locations were inputted into Principal component Analysis (PCA) using R software version 4.1.3. Based on PCA, it reveals that three tourism destinations are classified with area percentage of SUCI less than 50% while the other 11 destinations are classified with area percentage of SUCI more than 50%. In addition, characteristics of tourism destinations with SUCI area percentage less than 50% are identified to have low area percentage of NDBI ≤ -0.17, NDVI > 0.3, and UI < -0.2.

Geospatial Analysis Of Environmental, Tick, And Host Interactions With Rocky Mountain Spotted Fever In The Southwestern United States, Al Ekram Elahee Hridoy
