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.

Historically water-rich Florida …

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 …

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 …

Response Of Benthic Foraminifera To Ocean Acidification And Impact On Florida's Carbonate Sediment Production, Paul O. Knorr

USF Tampa Graduate Theses and Dissertations

Increasing concentrations of atmospheric CO2 are in dynamic equilibrium with the oceans. The absorption of CO2 by seawater causes a decrease in seawater pH and calcite saturation state (SS). This process, termed ocean acidification, exerts deleterious effects on marine calcifiers. Studies of symbiont-bearing large benthic foraminifera (LBF) have reported a generally unfavorable response to increased concentrations of carbon dioxide ([CO2]).

Experiments and analyses were undertaken to examine the effect of increased [CO2] on the growth rate, ultrastructure, stable isotopes of carbon and oxygen, as well as Mg/Ca of the high-Mg miliolid Archaias angulatus and the low-Mg rotalid Amphistegina gibbosa. A …
