An Interpretive Plan Guide For Wilderness Park In Lincoln, Nebraska, Rachel J. Ward

Community and Regional Planning Program: Professional Projects

Wilderness Park, located in Lancaster County, Nebraska, is a public park of unique ecological and historical value to the city of Lincoln and to the surrounding region. The natural and historical features of the park present an opportunity to communicate environmental and historical topics that are relevant on local, national, and global levels, as well as inspire a lively sense of pride in the community. The problem is that many topics relevant to Wilderness Park are not currently being interpreted at the park, and that there are relatively few interpretive resources available to park visitors.

Use Of Unmanned Aerial Vehicles (Uav) For Urban Tree Inventories, Brian Ritter

All Theses

In contrast to standard aerial imagery, unmanned aerial systems (UAS) utilize recent technological advances to provide an affordable alternative for imagery acquisition. Increased value can be realized through clarity and detail providing higher resolution (2-5 cm) over traditional products. Many natural resource disciplines such as urban forestry will benefit from UAS. Tree inventories for risk assessment, biodiversity, planning, and design can be efficiently achieved with the UAS. Recent advances in photogrammetric processing have proved automated methods for three dimensional rendering of aerial imagery. Point clouds can be generated from images providing additional benefits. Association of spatial locational information within the …

Managing Regional Water Resources Amidst Rapid Urbanization In Southwest Florida: A Case Study, Nicole Owusua Caesar

USF Tampa Graduate Theses and Dissertations

Experts and organizations involved in freshwater resources management have emphasized the importance of long-term urban resource planning and management that considers the tight coupling which exists between human - nature - technology systems. The resistance of contemporary urban growth efforts to consider resource carrying capacities and ecosystem requirements has led to costly unintended consequences including the deterioration of natural capital and their associated ecosystem services, and the degradation of water resource flows. As these problems continue to worsen, resource experts have called for the development of a new water resource management paradigm inclusive of various sustainability criteria.

Connecting Institutional Discourses And Everyday Understandings Of Climate Change: Viewpoints From A Suburban Neighborhood In Tampa, Florida, Christopher Metzger

USF Tampa Graduate Theses and Dissertations

Despite a general consensus regarding anthropogenic global climate change across the international scientific community, many of the major greenhouse gas producers in the world, especially the United States, are hesitant to implement strict emissions regulations. According to some prominent atmospheric scientists, such as James Hansen and Michael Mann, if industrialized countries continue to produce carbon emissions at current rates, an irreversible planetary tipping point of raising temperatures 2°C above pre-industrial levels could be reached in less than 40 years. Societies have a wealth of information from the natural sciences to understand the climate problem and currently possess the technological means …

Assessing The Environmental Justice Implications Of Flood Hazards In Miami, Florida, Marilyn Christina Montgomery

USF Tampa Graduate Theses and Dissertations

While environmental justice (EJ) research in the U.S. has traditionally focused on inequities in the distribution of technological hazards, the disproportionate impacts of Hurricane Katrina on racial minorities and socioeconomically disadvantaged households have prompted researchers to investigate the EJ implications of natural hazards such as flooding. Recent EJ research has also emphasized the need to examine social inequities in access to environmental amenities. Unlike technological hazards such as air pollution and toxic waste sites, areas exposed to natural hazards such as hurricanes and floods have indivisible amenities associated with them. Coastal property owners are exposed to flood hazards, but also …

The Impact Of Internet Gis On Access To Water Quality Information, Joseph H. Hoover

Electronic Theses and Dissertations

Empowering citizens to comprehend complex environmental issues affecting their daily lives is essential to sustaining a healthy and informed public. The work of many environmental nongovernmental organizations (ENGOs) and institutions of higher education (IHEs) center around helping their stakeholders become informed of, and in turn, better understand complex environmental problems. However, providing individual stakeholders with knowledge about environmental issues that is easily accessible and understandable represents a recurring challenge in today's society. As a result, a gap continues to exist between that which is known about environmental problems and the public's awareness and understanding of those issues. Arsenic contamination of …

Interannual Variation In Biomass Burning And Fire Seasonality Derived From Geostationary Satellite Data Across The Contiguous United States From 1995 To 2011, Xiaoyang Zhang, Shobha Kondragunta, David Roy

GSCE Faculty Publications

Wildfires exhibit a strong seasonality that is driven by climatic factors and human activities. Although the fire seasonality is commonly determined using burned area and fire frequency, it could also be quantified using biomass consumption estimates that directly represent biomass loss (a combination of the area burned and the fuel loading). Therefore, in this study a data set of long-term biomass consumed was derived from geostationary satellite data to explore the interannual variation in the fire seasonality and the possible impacts of climate change and land management practices across the Contiguous United States (CONUS). Specifically, daily biomass consumed data were …

Owning Our Food System: Urban Community Gardening And Local Food Movements, Paige A. Edwards

Masters Theses

Food is a means of examining culture, including identity, autonomy and power. It creates relationships and memories between people via shared connections. Through food, I explore local food movements and urban community gardening.

We both ingest and produce garden-grown foods. This movement is often described as simple nostalgia. I suggest that it is a response against heavily processed foods within a system reliant on mass produced food. This desire for ownership pushes community gardens and other counter-hegemonic spaces forward in their goals of using social practice to challenge the established food industry and take control within their own lives.

Geography Faculty Publications and Presentations

In order to inform natural resource policy and land management decisions, landscape values mapping (LVM) is increasingly used to collect data about the meanings that people attach to places and the activities associated with those places. This type of mapping provides geographically referenced data on areas of high density of values or associated with different types of values. This article focuses on issues and challenges that commonly occur in LVM, drawing on lessons learned in the US Forest Service Olympic Peninsula Human Ecology Mapping Project. The discussion covers choosing a spatial scale for collecting data, creating the base map, developing …

In Harm's Way: How Philadelphia's Urban Renewal Practices Steered Marginal People To Marginal Land, Katera Ya'shea Moore

Dissertations, Theses, and Capstone Projects

The dumping of locally unwanted land uses (LULUs) on marginal communities has been well documented, however environmental justice scholars have rarely written about how marginal groups have come to occupy their landscapes, particularly when natural hazards lie beneath.

This dissertation research focuses on a broad definition of the environment that includes the built, social, and physical. I am interested in extending Logan and Molotch's Growth Machine theory to consider how the political and economic elite guided the urban renewal process to place particular communities on particular landscapes, despite the presence of a flooding hazard. To understand this issue, I examined …

Spatial Analysis Of Post-Hurricane Katrina Thermal Pattern And Intensity In Greater New Orleans: Implications For Urban Heat Island Research, Aram P. Lief

LSU New Orleans Theses and Dissertations

In 2005, Hurricane Katrina’s diverse impacts on the Greater New Orleans area included damaged and destroyed trees, and other despoiled vegetation, which also increased the exposure of artificial and bare surfaces, known factors that contribute to the climatic phenomenon known as the urban heat island (UHI). This is an investigation of UHI in the aftermath of Hurricane Katrina, which entails the analysis of pre and post-hurricane Katrina thermal imagery of the study area, including changes to surface heat patterns and vegetative cover. Imagery from Landsat TM was used to show changes to the pattern and intensity of the UHI effect, …

Addressing Water Resource Issues In Barbados Through An Isotopic And Atmospheric Characterization Of Precipitation Variability, Veronica Hall

Masters Theses & Specialist Projects

Numerous studies have analyzed isotopic variation of meteoric and dripwater in karst environments for paleoclimate reconstructions or aquifer recharge capacity. What is poorly understood is how the isotopic signal of δ¹⁸O and δ²H is transferred through the hydrologic cycle based upon storm type, frequency, intensity, and teleconnection activity in the tropical karst areas. At Harrison’s Cave, Barbados, a Hobo Onset event data logger was attached to a tipping bucket rain gauge to count the tips and record the total rainfall every 10 minutes. In the cave a Hobo data logger was used to record relative humidity …

Land Cover Change And Its Impacts On A Flash Flood-Producing Rain Event In Eastern Kentucky, William N. Rodgers

Masters Theses & Specialist Projects

Eastern Kentucky is a 35-county region that is a part of the Cumberland Plateau of the Appalachian Mountains. With mountaintop removal and associated land cover change (LCC) (primarily deforestation), it is hypothesized that there would be changes in various atmospheric boundary layer parameters and precipitation. In this research, we have conducted sensitivity experiments of atmospheric response of a significant flash flood-producing rainfall event by modifying land cover and topography. These reflect recent LCC, including mountaintop removal (MTR). We have used the Weather Research and Forecasting (WRF) model for this purpose. The study found changes in amount, location, and timing of …

Troubled Waters: Georgia, Florida And Alabama's Conflict Over The Waters Of The Acf River Basin, Johnny King Alaziz Wong

USF Tampa Graduate Theses and Dissertations

Since 1989, the co-riparian States of Georgia, Florida and Alabama have been locked in an overt and institutionalized conflict to secure access to the waters of the Apalachicola-Chattahoochee-Flint (ACF) River Basin. In 1997, in an effort to end this interstate conflict which had earned the reputation as the longest water conflict in U.S. history, public officials at the federal and state scales agreed to suspend all pending litigation against one another and concurrently deployed a dispute resolution mechanism, known as `compact negotiations,' in the hope of equitably allocating the waters of the ACF Basin. Despite proclamations by public officials, exclaiming …

"Nature Is Pushing One Way And People Are Pushing The Other": A Political Ecology Of Forest Transitions In Western Montgomery County, Pa, Megan Elizabeth Maccaroni

Environment and Sustainability Honors Papers

Forests in Southeastern Pennsylvania have been shaped by a number of anthropocentric factors over the past century, with many areas experiencing a recent trend towards forest recovery. Studies on forest dynamics have shown that most developed regions exhibit a forest transition, which begins when land is cleared for natural resource extraction (e.g., agriculture, forestry) during an early development stage. Then as a population grows and food production needs are met, rural peoples begin to migrate to the city, and a feeling of scarcity of trees develops that may lead to changes in land management attitudes, and many formerly deforested areas …

Urban Foraging And The Relational Ecologies Of Belonging, Melissa R. Poe, Joyce Lecompte, Rebecca J. Mclain, Patrick T. Hurley

Environment and Sustainability Faculty Publications

Through a discussion of urban foraging in Seattle, Washington, USA, we examine how people's plant and mushroom harvesting practices in cities are linked to relationships with species, spaces, and ecologies. Bringing a relational approach to political ecology, we discuss the ways that these particular nature–society relationships are formed, legitimated, and mobilized in discursive and material ways in urban ecosystems. Engaging closely with and as foragers, we develop an ethnographically grounded ‘relational ecologies of belonging’ framework to conceptualize and examine three constituent themes: cultural belonging and identity, belonging and place, and belonging and more-than-human agency. Through this case study, we show …

No Fracking Way! A Study On The Spatial Patterns Of And Changes In Perception And Distance From A Michigan Horizontal Hydraulic Fracturing Site, Shannon Mcewen

Masters Theses

The research investigates whether Michigan residents' perception of risk from an oil and natural gas (ONG) well site that employs the use of horizontal hydraulic fracturing (fracking) changes with distance. The research goal is to determine if residents that live farther from a fracking site perceive it to be more dangerous than those who live closer. Secondary research goals include determining if increasing distance from a fracking site cause residents to overestimate their proximity to a fracking site and if gender and education levels have an effect on residents' perception levels. Data were collected from residents in three counties in …

Suburban Heat Islands: The Influence Of Residential Minimum Lot Size Zoning On Surface Heat Islands In Somerset County, New Jersey, Jennifer Renee Cox

Dissertations, Theses, and Capstone Projects

The process of suburbanization blurs regional bounds, forms mega-regions and fosters the expansion of multifaceted environmental problems, such as the urban heat island (UHI) effect. Defined by differences in air- and surface- temperature between rural and urban areas, UHI is the result of the characteristics of urbanization which modify the land surface condition, urban geometry, thermal properties of construction materials, anthropogenic heat and air pollution, which increase storage and re-radiation of heat to the atmosphere. Climate change is predicted to worsen the UHI effect. Hence, the objective of this research to characterize the UHI effect as it pertains to suburban …

Pan-Baltic Stakeholders’ Dialogue On Msp : Synthesis Report From Partiseapate Single-Sector Workshops Held In 2013, Anda Ruskele, Ilze Kalvane, Kristina Veidemane, Joanna Przedrzymirska, Angela Schultz-Zehden, Daniel Depellegrin, Nerijus BlažAuskas, Peter Askman, Henrik Nilsson, Jonas Pålsson, Bettina Käppeler, ElīNa Veidemane

PartiSEApate

For a sustainable and integrated planning of the sea space across the Baltic Sea region, planners and stakeholders have to be engaged in holistic, pan-Baltic thinking where the whole Baltic Sea is considered as one ecosystem and one planning space. However MSP related experiences so far shows that interests are often expressed from one sector or one national or regional perspective only. There is a lack of information exchange between the different maritime sectors as well MSP support structures (i.e. data providers and researchers) and spatial planners. And at the same time there is insufficient communication within the sectors at …

Evaluation Of Swat Model Applicability In A First-Order Agricultural Watershed In Southern Ontario, Ibrahim O. Rashid

Geography and Environmental Studies Theses and Dissertations

The primary objective of most agricultural operations including those at the Strawberry Creek Watershed is to maximize crop yield. This often requires the input of additional nutrients to enhance soil fertility, and installation of artificial subsurface drainage to curtail water-logging of soils with very low hydraulic conductivity. However, the combination of additional nutrients and subsurface drainage often leads to a disruption of the existing hydrochemical regime. Excess nitrate and phosphorus export to surface water bodies may yield negative environmental impacts, including the eutrophication of downstream areas. To address this issue, a modeling technique was deployed to quantify and assess these …
