Human-Centered Avalanche Susceptibility Mapping, Lindsey L. Rotche
Geography ETDs
With backcountry winter travel increasing in popularity, the importance of accessible avalanche safety information is crucial. Widely accessible avalanche backcountry maps use slope shading to show where avalanches are likely to start. Instead of focusing on the hazard of an avalanche starting in a specific location, this project shifted the cartographic emphasis of avalanche susceptibility maps to show risk to a human traveling in the terrain. I developed a methodology to incorporate possible avalanche runouts, terrain traps, and connected slopes while reducing false certainty of the visualization. To provide a more comprehensive representation of susceptible terrain, I integrated aspect, distance …

Inland Tropical Cyclone Intensity Decay In The Continental United States, Yijie Zhu
USF Tampa Graduate Theses and Dissertations
Tropical cyclone (TC) hazard preparation is mostly focused on coastal cities with less attention typically paid to inland regions. The impact of TCs that propagate far inland is often underestimated and can cause unexpected loss of life and economic loss. This dissertation aims to understand the decay process of TCs during the post-landfall stage by answering three main research questions: (1) What are the general patterns of inland tropical cyclones, including spatial variations, decay rates, and translation speeds? (2) Are there temporal changes in the intensity decay from inland moving hurricanes? (3) How is the hurricane post-landfall dissipation related to …

Destruction caused by violent conflicts play a big role in understanding the dynamics and consequences of conflicts, which is now the focus of a large body of ongoing literature in economics and political science. However, existing data on conflict largely come from news or eyewitness reports, which makes it incomplete, potentially unreliable, and biased for ongoing conflicts. Using satellite images and deep learning techniques, we can automatically extract objective information on violent events. To automate this process, we created a dataset of high-resolution satellite images of Syria and manually annotated the destroyed areas pixel-wise. Then, we used this dataset to …

National Food Security, Immigration Reform, And The Importance Of Worker Engagement In Agricultural Guestworker Debates, Laura-Anne Minkoff-Zern
Food Studies - All Scholarship
This article looks at the United States’ federal H-2A Temporary Agricultural Visa Program and reforms proposed by the Farm Workforce Modernization Act. In this policy analysis, we draw on media content analysis and qualitative interviews to compare the viewpoints of farmers, workers, grower and worker advocacy groups, intermediary agents, and politicians. We find that perspectives on the program are dependent upon actors’ level of direct interaction with workers. Moderate-sized farmers and regionally based worker advocacy groups tend to be the most concerned with day-to-day program operations and fair working conditions. In contrast, national-level advocacy groups, intermediary agents, and politicians are …

Climate Disasters, Mass Violence, And Human Mobility In South Sudan: Through A Gender Lens, Marisa O. Ensor
Genocide Studies and Prevention: An International Journal
This article examines the links between gender, mass violence, climate change, and displacement in South Sudan. I argue for risk-informed gender-sensitive strategies that incorporate local capacities and sources of resilience. When civil war engulfed South Sudan again in 2013, egregious human rights violations, including sexual and gender-based violence, were perpetrated with near complete impunity. As the national army was divided along Dinka-Nuer ethnic lines, soldiers from each faction turned against each other in a deadly pattern of revenge and counter-revenge attacks that soon spread across the national territory. Inter-communal conflicts also intensified, often centering on competition over land for pasture, …

A Gis Suitability Model Evaluating Habitat Characteristics Influencing Beaver (Castor Canadensis) Lodge Site Selection And Lodge Occupancy In Central Adirondacks, New York, Amanda K. Jacobs
Theses - ALL
The North American beaver (Castor canadensis) represents a quintessential example of an "ecosystem engineer." Yet the species' landscape-scale impacts on hydrology, geomorphology, and ecosystem ecology are not uniformly distributed through landscapes or time. Understanding beaver lodge site selection and lodge fidelity through time can help to predict where the greatest effects of beaver activity may occur. In this research project, I seek to understand the relationships between beaver habitat suitability, the habitat variables that currently define suitable areas, and lodge occupancy over time. Using Geographic Information Systems (GIS) to model habitat suitability, I use hydrologic, vegetative, and physiographic variables to …
