Influences On The Establishment Of County Wildfire Risk Mitigation: The Case Of California's Fire Safe Councils, Timothy Richard Soileau

LSU Master's Theses

In response to increased annual wildfire destruction and insufficient wildfire mitigation approaches from the federal government, the state of California adopted Public Resources Code Sections 4290 and 4291 in the year 1991. These laws force the removal of fire-causing agents from public and private areas, and establish what is known as defensible space. Defensible space is defined in Section 4291 as the area within the perimeter of a parcel, development, neighborhood, or community where basic wildland fire protection practices and measures are implemented, providing the key point of defense from an approaching wildfire or escaping structure fire. One method to …

A Bioeconomic Supply Model For Louisiana Nutria And Impacts On Wetlands Conservation Associated With Economic Incentives, Cheikhna Ould Dedah

LSU Master's Theses

Nutria (Mayocastor) were first introduced to Louisiana in 1938. With few natural predators and high prolific productivity, they became well established in the surrounding coastal marsh within a few years. Prior to 1980’s, as a result of high demand for nutria products from European countries, harvest pressure was sufficient to keep the population in ‘check’ with their wetlands capacity. By the mid-1980’s, however, prices had fallen sharply, culminating in declining annual harvests and an increasing population. Because of their feeding habits, the increased nutria population has resulted in a substantial amount of wetland degradation. In this thesis, a long-run bioeconomic …

Hydrography, Suspended Sediments, Chlorophyll A, Chromophoric Dissolved Organic Matter And Optical Characteristics Of The Pearl River (Zhujiang) Estuary During July And November, 1998, Wendy Lynn Woods

Open Access Dissertations

The Pearl River (Zhujiang) is the second largest river in China and the largest in southern China, with a strongly seasonal discharge driven by Asian monsoon rainfall patterns. Optical characteristics of the plume region are expected to strongly affect light limitation of primary production and the interpretation of satellite remote sensing data. The river is enriched with nutrients from agriculture, aquaculture, and human waste disposal, and experiences frequent phytoplankton blooms. An understanding of factors controlling phytoplankton primary production is currently lacking, but is essential for effective water quality management. This study reports on the hydrography (temperature, salinity, dissolved oxygen, pH, …

Evaluation Of A Novel Method Of Predicting Estrogen Activity Of A Group Of Structurally Diverse Compounds, Daniel Consoer

LSU Master's Theses

The number of environmental chemicals found to have some level of endocrine activity has led to concern about the possible effects these compounds could have on human health and the health of other species, populations, and possibly whole ecosystems. The United States Environmental Protection Agency has been charged with testing a large number of these compounds, called endocrine-disrupting chemicals or hormonally active agents for hormonal activity. Limited testing resources have led to a call for alternate methods of screening, possibly for use in prioritizing this list to assist in efficient allocation of resources for further testing. This study describes a …

An Analysis Of The Variables That Influence A Country's Decision To Ratify The Stockholm Convention On Persistent Organic Pollutants, Tokesha Marie Collins

LSU Master's Theses

The objective of this thesis is to identify key factors that influence a country to ratify the Persistent Organic Pollutants (POPs) Treaty. The POPs treaty seeks to eliminate or reduce the emissions of 12 POPs. I will examine the links between the countries that have ratified the POPs treaty in an effort to identify variables that may have influenced a country's decision to ratify the treaty. For each of the 165 nations in my dataset, I will examine economic, social, geographic, health, and political indicators and history of malaria and determine if a relationship exists between these variables and treaty …

Riding Out The Risks: An Ethnographic Study Of Risk Perceptions In A South Louisiana Bayou Community, Susan Camille Manning

LSU Master's Theses

This ethnographic study explores the risk perceptions of a small unincorporated coastal community in southeastern Louisiana. This community has experienced social and environmental change due to events including tropical storms and hurricanes, erosion, subsidence, oil and gas activities, development, and the impact of global seafood markets. Many global risk perception studies have focused on the perception of risk to human health and property connected with natural and technological disasters, but few have explored the issue of minorities and small at-risk communities. To explore this theoretical and methodological gap, this study uses a variety of qualitative ethnographic methods to examine a …

Putting Down Roots In Environmental Literacy: A Study Of Middle School Students' Participation In Louisiana Sea Grant's Coastal Roots Project, Rachel L. Somers

LSU Master's Theses

Few people realize that in Louisiana land is lost to open water at about a rate of 24 square miles a year, faster than anywhere else in the world (Barras, Beville, Britsch, Hartley, Hawes, Jonston, Kemp, Kinler, Martucci, Porthouse, Reed, Roy, Sapkota, & Suhayda, 2003). Not only is the public low to moderately environmentally literate, there is a need to reach students early on to ensure the greatest benefit. This is the main reason why Louisiana Sea Grant¡¦s Coastal Roots Wetland Seedling Nursery Project (Coastal Roots) came into inception. The goal of the project is to improve environmental literacy of …

Environmental Benefits Realized From Eradication Of The Non-Indigenous Insect Anthonomus Grandis Boheman, The Cotton Boll Weevil, Marc Stephen Bordelon

LSU Master's Theses

At least one third of the insecticide used in agriculture has been used to control the boll weevil in cotton. Historically, these insecticides have been toxic to humans and harsh on the environment. In addition, the intensive use of chemical insecticides to control the boll weevil results in the disruption of naturally occurring biological control factors that regulate other insect pest populations causing a chain reaction of secondary pest populations that require treatment followed by resurgence and repeat treatment. This situation has resulted in the development of resistance to insecticides, high control costs and unacceptable levels of chemical insecticide contamination …

Identifying Asphalt Construction As A Point Source Emitter Of Volatile Organic Compounds Near The Louisiana State University Ozone Monitoring Station, Sean Jason Kice

LSU Master's Theses

The EPA has classified Baton Rouge as a non-attainment area for ozone pollution for many years. Since then Photochemical Assessment Monitoring Stations (PAMS) and other ozone monitoring stations around the metropolitan area have monitored for ozone, NOx, and more than 50 volatile organic compounds (VOCs) which are considered precursors to ozone pollution. Traditionally, automobile engines and industrial plants and refineries have been blamed as major point sources for VOC emissions and the ozone pollution they cause. This research focuses on another possible point source for failing ozone levels at one of the ozone monitoring stations located on the campus of …

Sinker Cypress: Treasures Of A Lost Landscape, Christopher Aubrey Hurst

LSU Master's Theses

Sinker cypress (Taxodium spp.) logs are timbers that were lost during transit from harvest locations in the swamps and mill sites during the industrial cypress harvest from 1880-1930. A small industry has developed, concentrated on the recovery of sinker logs. Most of the persons involved in the recovery of sinker cypress, mill the logs into lumber, and sell the timber directly to consumers or to distributors. A smaller number of pullers retain the logs for personal use. Recovery operations are a costly endeavor and require a significant investment on the part of the harvesters. Most pullers are owner/operators who do …

Assessment Of Water Conservation Technique In Rice Culture To Develop Water Use Policies, Manoch Kongchum

LSU Master's Theses

The rapid growth of world population has resulted in significantly increased global water demand. According to a recent report on limited water supply, conservation techniques and water use policies are needed to preserve water resources. Worldwide agriculture is the largest consumer of water, particularly for growing rice. Water use for rice production was chosen because rice will continue to be a staple crop for the majority of the world’s population and because of its pervasive use of water. Hence, this thesis was designed to investigate water conservation possibilities for rice production in two water management regimes: alternate flooding and drying, …

A Co-Orientational Analysis Of Public Involvement Perceptions In The Transportation Process: A Case Study, Kristen E. Carson

USF Tampa Graduate Theses and Dissertations

This study explored public involvement within the Florida Department of Transportation (FDOT) using the co-orientational theory. Effective public involvement gives the public opportunities to be involved early in the planning and implementation of transportation projects that directly affect or may concern them. The co-orientational model looks at what an organization (FDOT) thinks about an issue (public involvement), what the public thinks of the issue, what the organization thinks the public thinks about the issue, and what the public thinks the organization thinks about the issue.

This study investigated whether the FDOT management has an accurate understanding of the perceptions of …

Environmental Science and Management Faculty Publications and Presentations

Nonindigenous species have caused substantial environmental and economic damage to coastal areas. Moreover, the extent and impacts of nonindigenous species are increasing over time. To develop predictive models and to identify which areas should be targeted for impact mitigation or early detection, we need a basic foundation of knowledge about the spatial and temporal patterns of invasions. This project was developed because we lacked the necessary data to rigorously evaluate the patterns of coastal invasions. This collaborative project, between the Smithsonian Environmental Research Center, the National Estuarine Research Reserve System (NERRS) and the National Marine Sanctuary Program (NMSP), established a …

Designation Of The Southwest National Wildlife Refuge Complex As Wetlands Of International Importance Under Ramsar, Convention On Wetlands Of International Importance, Mitchell Ward Coffman

LSU Master's Theses

The historical loss and continued threat of loss of Louisiana wetlands is a major environmental concern for the United States and the world. In 1971, the Ramsar Convention, an international environmental treaty was ratified to specifically address conservation planning and land use management issues involving wetlands of the world. Ramsar provides an international designation award called, the Wetlands of International Importance List, which formally acknowledges globally important wetland landscapes. Ramsar outlines specific criterion nominated wetland sites must possess for consideration of this listing.

The Southwest Louisiana National Wildlife Refuge Complex is an excellent candidate for nomination to the Ramsar Convention …

Experimental Investigation Of Dynamic Interfacial Interactions At Reservoir Conditions, Wei Xu

LSU Master's Theses

Much of the research on wettability in the existing literature has been done using stocktank oils and at ambient conditions. The main objective of this study is therefore to examine the validity of ambient measurements in inferring in-situ reservoir wettability. For this purpose, Drop-Shape-Analysis for interfacial tension and Dual-Drop-Dual-Crystal (DDDC) contact angle measurements have been carried out using dolomite rock, Yates reservoir stocktank and live crude oils and Yates synthetic brine at Yates reservoir conditions of 82oF and 700 psi. Two types of surfactants (nonionic and anionic) in varying concentrations have been used to study the effect of surfactants on …

An "Ecolodge" In Thailand: A Site Design Based Upon The Local Vernacular Village, Pudtan Chantarangkul

LSU Master's Theses

This thesis began from my interest in using indigenous architectural and dwelling patterns of fishing villages in coastal Thailand as a model for a new sustainable community. The provincial government has a policy promoting longstay tourism for affluent retirees from other countries, enabling them to experience the natural, historical, and cultural heritage of the area at an economical cost. To fulfill the local government's policy and my intention to design such a facility, this thesis proposes to design an international "ecolodge" for a site near Yisan Village. The area is very peaceful yet it is not so far from downtown …
