Ensemble Encoder-Decoder Models For Predicting Land Transformation, Pariya Pourmohammadi

Graduate Theses, Dissertations, and Problem Reports (ETD)

In studying dynamic and complex processes which are influenced by a system of inter-connected driving variables, it is crucial to apply models that can learn the complexity of the interactions. Land transformation is one of such complex processes, prediction of which can help to mitigate severe climate situations and improve the resiliency of communities. In this study, a multi-spectral set of data cubes is used to capture various characteristics of a geographic region. Based on the data cube, a feature space is constructed using socio-economic attributes, terrain characteristics, and landscape traits of the study region. Two-dimensional and three-dimensional convolutional neural …

Women, Water, And Well-Being: Gendered Experiences Of Household Water Contamination In Parkersburg, West Virginia, Emily Brooke Tingler

Graduate Theses, Dissertations, and Problem Reports (ETD)

DuPont Washington Works chemical plant knowingly pumped hundreds of thousands of pounds of toxic C8 waste into local waterways, water tables, and landfills for over 40 years, contaminating the drinking water for more than 100,000 residents in and around Parkersburg, West Virginia. Drawing on feminist political ecology and the political ecology of water with literature on perceptions of risk in contaminated communities, environmental reproductive justice, modern water, and hydrosocial waterscapes, I examine, through a qualitative case study, the lived experiences of women who have an intimate understanding of C8 water contamination from the DuPont Washington Works chemical plant. Specifically, I …

Advancing The Spatial Turn In History Through Deep Mapping: Ghost Maps, Neogeography, And Frederick Jackson Turner, Jessica L. Mathai

Sexual And Place-Based Identity: A Life Course Analysis Of Lgbtq+ Undergraduate Understandings Of Climate Change In Appalachia, Brandon Anthony Rothrock

Graduate Theses, Dissertations, and Problem Reports (ETD)

LGBTQ+ persons face heightened vulnerability to climate change-induced disasters due to their sexual orientation, gender identity, and gender expression. Yet, there are limited studies that examine how LGBTQ+ students, particularly in a higher-education setting, understand climate change in relation to their sexuality. With a majority of studies on LGBTQ+ persons and climate change focusing on LGBTQ+ experience during and after disaster, there is a gap in understanding LGBTQ+ perceptions of climate change in the day-to-day. Particularly in Appalachia, a region characterized by a strong place-attachment to and a collective identity with the natural environment, studies of marginalized groups’ perceptions of …

Can Stable Isotopes From Tree Rings Improve Our Understanding Of Past Variability In The Southern Annular Mode?, Zachary Grzywacz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Few annually dated stable isotope records exist across Oceania. In mid- to high-latitude locations in South America, tree-ring stable isotopes provide information about past climate dynamics such as the Southern Annular Mode (SAM). The SAM drives latitudinal shifts in Southern Hemisphere westerly winds, influencing temperature and moisture delivery across the mid- to high-latitudes, including Tasmania. Combinations of paleoclimate proxies from across the Southern Ocean might provide insight into dynamic processes like the SAM that are difficult to measure with a single proxy. Measuring stable carbon and oxygen isotope ratios from tree rings in Tasmania could provide complementary data to contribute …

Assessing Synthetic Aperture Radar (Sar)-Derived Temporal Patterns And Digital Terrain Data For Palustrine Wetland Mapping, Jaimee L. Pyron

Graduate Theses, Dissertations, and Problem Reports (ETD)

Palustrine wetland systems are important ecosystems and provide numerous ecosystems services to support society. Unfortunately, they remain under constant threat of devastation due to land use practices and global climate change, which underscores the need to identify, map, and monitor these landscape features. This study explores harmonic coefficients and seasonal median values derived from Sentinel-1 synthetic aperture radar (SAR) data, as well as digital elevation model (DEM)-derived terrain variables, to predict palustrine wetland locations in the Vermont counties of Bennington, Chittenden, and Essex. Support vector machine (SVM) and random forest (RF) machine learning models were used with various combinations of …

O Espaço E O Tempo Do Valor, David Harvey, Artur Renzo

Publications and Research

O artigo discute a lei do valor em Karl Marx como valor em movimento, que se faz valer no espaço e no tempo. Entende-se que o movimento não pode ocorrer no vácuo, sendo necessário abandonar a visão do valor que se move sem estar ancorado em nenhum lugar e passar a enxergá-lo criando geografias de cidades e redes de transportes; formando paisagens agrícolas para a produção de alimentos e matérias-primas; englobando fluxos de pessoas, bens e informações; determinando configurações territoriais de valores fundiários e habilidades de trabalho; organizando espaços de trabalho, estruturas de governo e administração. Conclui-se que há três …

Assessing Airborne Radar To Map Glacier Elevations In Alpine Terrain Including Estimated Glacier Volume Change, Bryce Allen Glenn

Dissertations and Theses

Alpine glaciers and perennial snowfields (G&PS) are important hydrologically and ecologically, providing meltwater during the hottest and driest summer periods. Climate warming shrinks these natural reservoirs while temporarily providing increased streamflow. To assess regional changes in glacier volume, from which contribution to streamflow can be estimated, I used NASA's Airborne Glacier and Ice Surface Topography Interferometer (GLISTIN). This instrument mapped the surface topography of alpine glaciers; differencing these elevations from historic elevations derived from topographic maps, volume change is calculated. GLISTIN was flown over the glacier-populated mountain ranges of the western U.S. Of the 3289 glaciers and perennial snowfields with …

Environmental And Spatial Factors Affecting Surface Water Quality In A Himalayan Watershed, Central Nepal, Janardan Mainali, Heejun Chang

Geography Faculty Publications and Presentations

Various spatial interrelationships among sampling stations are not well explored in the spatial modeling of water quality literature. This research explores the relationship between water quality and various social, demographic, and topographic factors in an urbanizing watershed of Nepal with a comparison of different connectivity matrices to conceptualize spatial interrelationships. We collected electrical conductivity and dissolved oxygen data from surface water bodies using a handheld probe and used the data to establish relationships with land use, topography, and population density-based explanatory variables at both watershed and 100-m buffer scales. The linear regression model was compared with different eigenvector-based spatial filtering …

Green Stormwater Infrastructure Planning In Urban Landscapes: Understanding Context, Appearance, Meaning, And Perception, Mahbubur Meenar, Jordan Howell, Devon Moulton, Shane Walsh

School of Earth & Environment Departmental Research

Prior research has documented environmental and economic benefits of green stormwater infrastructure (GSI); literature on GSI social benefits is also becoming more prevalent among scholars around the world. This paper aims to understand whether GSI projects are considered as assets to urban neighborhoods or as projects that might introduce a new set of social concerns. Based on field observations of 238 GSI projects and 50 intercept interviews, we investigate selected social aspects of GSI, such as project context, visual appearance, recreational appeal, meaning, and public perception, in two neighboring US cities—Philadelphia and Camden. Analysis of field data and observation notes …

This Double Life, Jesse Vad

Capstones

The pandemic and recent push for racial justice kicked liberal suburbs into gear. Suburbanites in my home of Marin Count, California, spoke out against inequality and began to challenge society’s status quo.

But as I journey back home during the pandemic, I begin to take a deeper look at my suburban home. Beginning with real estate, I examine the supposed progressiveness of Marin.

Expanding The Boundaries Of Food Policy: The Turn To Equity In New York City, Nevin Cohen, Rositsa Ilieva

Publications and Research

Policymakers acknowledge that the food system is multidimensional and that social determinants affect diet-related health outcomes, yet cities have emphasized programs and policies narrowly connected to food access and nutritional health. Over the past fifteen years, the boundaries of food governance have expanded to include a wider range of issues and domains not previously considered within the purview of food policy, like labor, housing, and education policies. This paper illustrates the processes by which this shift occurs by presenting the case of New York City, which has broadened its food governance to a larger set of issues, requiring cross-sectoral initiatives …

Applying The Food-Energy-Water Nexus Approach To Urban Agriculture: From Few To Fewp (Food-Energy- Water-People), Silvio Caputo, Victoria Schoen, Kathrin Spect, Baptiste Grard, Chris Blythe, Nevin Cohen, Runrid Fox-Kämper, Jason Hawes, Joshua Newell, Lidia Poniży

Publications and Research

Many studies examine the correlation between the use of resources such as water, energy and land, and the production of food. These nexus studies focus predominantly on large scale systems, often considering the social dimensions only in terms of access to resources and participation in the decision- making process, rather than individual attitudes and behaviours with respect to resource use. Such a concept of the nexus is relevant to urban agriculture (UA), but it requires customisation to the particular characteristics of growing food in cities, which is practiced mainly at a small scale and produces not only food but also …

Reviewing Pesticide Impacts On Frogs To Suggest Management Applications In The Gambles Mill Eco-Corridor, Marc Gorman

Environmental Studies Senior Seminar Projects

For years, frog populations have been declining due to a variety of anthropogenic sources, including pesticide use. Pesticides work by inhibiting bodily functions in their target pest species, though they frequently have unintentional impacts on other life forms in an ecosystem. Some researchers have evaluated these effects, but their studies mainly focus on finding an LC50 - a concentration that will kill 50% of their test species sample. However, these LC50 levels are often higher than what would be found in nature, and pesticides have been shown to still impact species at lower concentrations. Thus, this study attempted to summarize …

Pollinator Habitat On The University Of Richmond Campus: Assessing The Success Of Pollinator Meadows In The Gambles Mill Eco-Corridor, Mary Berner

Environmental Studies Senior Seminar Projects

Globally, many insect pollinator populations are declining in response to anthropogenic harms including habitat loss due to land-use change and urbanization, climate change, increasing pesticide use, invasive species introductions, and increased pathogen transmission. In order to protect these insects, and the benefits they provide through pollination, habitat must be protected. Much of the effort to protect insect pollinator habitat is occurring in urban areas, where pollinators may struggle to find the resources they need to survive. The purpose of this study was to assess the success of three pollinator meadows created within the Gambles Mill Eco-Corridor (Eco-Corridor) on the University …
