Determination Towards Decision Of Public Response In Flood Situation: Case Study In Urban Flood Prone Area In Central Region In Thailand, I-Soon Raungratanaamporn

Applied Environmental Research

Public involvement has become a crucial part in increasing the efficiency of disaster management activities nowadays. In particular, collaboration between civil society and municipalities emerge in disaster situations because uncertainties in personal perception compel them to do so more than their own willingness to involved in disaster management activity. Since this appears to have occurred as a response to the 2011 flood situation in Thailand, the question is how a successful was this collaboration? The aim of this research is to identify factors influencing people's involvement in disaster management activity. The two study objectivesare as follows: (1) to elucidate the …

Effects Of Organic Fertilizer On Cd Bioavailability And Cd Accumulation In Rice Grown In Contaminated Paddy Soil, Mongkolchai Assawadithalerd, Meechai Siangliw, Chantra Tongcumpou

Applied Environmental Research

The effects of organic fertilizer on Cd phytoavailability and distribution in rice plants(Oryza sativaL.) were examined in pot and field experiments. The results of the pot experiment show that the addition of organic fertilizer increased the oxidizable Cd fraction(F3) and decreased the soluble and exchangeable Cd fraction (F1). There was also an increase in the dry matter yield when more organic fertilizer was applied. The Cd concentrations in the rice plant parts were observed in the following order: root > stem > grain. The accumulation index from the field experiment indicates that organic fertilizer application is likely to reducethe uptake of both …

Geochemistry And Protolith Determination Of The Hypersthene-Quartz-Oligoclase Gneiss From The Hudson Highlands, New York, Kathleen Miller

Theses, Dissertations and Culminating Projects

The hypersthene-quartz-oligoclase gneiss of the Hudson Highlands, NY mapped by Dodd (1965) has been of unknown origin due to complex field relations resulting from metamorphism and deformation during the Ottawan Orogeny, and a lack of geochemical data. The rock types in the Hudson Highlands and New Jersey Highlands are grouped into four general categories: metasedimentary gneisses, metaigneous gneisses, quartzofeldspathic gneisses, and syn-tectonic intrusive granitoid rocks (Dodd, 1965). Major element geochemistry and mineralogy of the Losee Metamorphic Suite of the physically contiguous New Jersey Highlands is similar to that of the hypersthene-quartzoligoclase gneiss of the Hudson Highlands. Based on the high …

Late Pliocene Ice-Rafted Debris Mass Accumulation Rates From Iodp Site U1359, Wilkes Land Continental Rise, Antarctica, Jessica Rosenberg

Theses, Dissertations and Culminating Projects

An assessment of sediments taken from the IODP (Integrated Ocean Drilling Program) Expedition 318, Core U1359A from the Wilkes Continental Land Rise, has been conducted at a high resolution to determine the response of the East Antarctic Ice Sheet to climate during the Late Pliocene. The section of core being studied dates back to ~3.7 to 2.7 million years ago (Ma). Studies can lead to an understanding of climate change in the future, from knowledge on how ice sheets have transformed in the past with similar atmospheric conditions to the present. Samples from this record were analyzed based on the …

Chemically Catalyzed Phytoremediation Of 2,4,6-Trinitrotoluene (Tnt) Contaminated Soil By Vetiver Grass (Chrysopogon Zizanioides L.), Padmini Das

Theses, Dissertations and Culminating Projects

Urban sprawl in big cities often encroaches on military land, where residual toxic explosive compounds like 2, 4, 6-trinitrotoluene (TNT) in soil could pose a serious health risk. Additionally, in demilitarized areas, lack of sustainable remediation techniques hinder the much needed residential development.. Phytoremediation is an environmentally safe and cost effective solution; however, the characterized low aqueous solubility of nitroaromatic compounds resulting in limited availability of TNT for plant uptake is a major constraint. To overcome this limitation, we propose a new innovative phytoremediation technique using urea, a common nitrogen fertilizer, as a chaotropic agent, to enhance the solubility of …

The Effectiveness Of Venue Strategies For Environmental Communication In Non-Agricultural, School Integrated Pest Management Campaigns, Marcia L. Anderson

Theses, Dissertations and Culminating Projects

Pesticides have become a preferred approach to controlling pest problems in many, schools and childcare centers, despite the exposure hazards to children and the environment. The only other place where children spend more time is in their homes. Children are continually and unknowingly exposed to pests and pesticides while in and around school buildings. Pesticides are used on athletic fields, play areas, in cafeterias, classrooms, and more. Reducing the use of pesticides from the school environment is critical to lowering children’s total exposure.

This research tests ways of communicating about Integrated Pest Management to a number of school-related target audiences. …

Spatial Decision Support Systems For Sustainable Urban Redevelopment, Amy V. Johnson-Ferdinand

Theses, Dissertations and Culminating Projects

A recent United Nations study concludes that worldwide population will grow from approximately 7 billion today to 9.3 billion in 2050 and 10.1 billion in 2100. Nowhere is this population growth more evident than in the major cities of the world. For the first time in history, a majority of the world’s people lived in cities. In 1950, by comparison, less than 30% of the world’s population dwelled in cities. This rapid growth of population, coupled with an aging infrastructure, and the abandoning of urban manufacturing sites, creates an urgent need for inner city revitalization. There are several urban areas …

Antecedents Of Environmentally Sensitive Consumer Behaviors : An Investigation Of Goal Framing Theory, Naz Onel

Theses, Dissertations and Culminating Projects

Human behavior strongly impacts environmental quality. Altering behaviors that significantly affect the well-being of the environment can reduce the impact of human actions in a way that could help overcome environmental deterioration. However, this requires understanding the factors affecting consumer behavior towards acting in a more ecologically conscious manner. Further, the effects of these factors could vary based on the different types of consumer behaviors, such as environmentally sensitive purchase (acquisition), usage, and post-use (disposal) behaviors. The purpose of this dissertation is to analyze the predicting factors of different types of environmentally sensitive consumer behavior by examining the extent to …

Organic Geochemical Investigations Of Urban Sediments By Pyrolysis-Gas Chromatography / Mass Spectroscopy, Kevin Olsen

Theses, Dissertations and Culminating Projects

Pyrolysis-Gas Chromatography / Mass Spectrometry (Py-GC/MS) can be used to study the organic matter in sedimentary environments.

An urban sediment is not simply defined by proximity to a city. Because cities have anthropogenic contamination, one important urban sediment characteristic is ongoing recontamination. Another is legacy contamination from industrial activity and a third is the alteration of natural bio-geochemical systems.

Two case studies are presented. The surface sediments of the Gateway National Recreation Area were sampled during the summer of 2007. The ratio of two pyrolysis products, Vinylguiacol, from terrestrial plant lignins, and Indole, from proteins, (VGI Index) is moderately well …

Characterization Of Eocene-Oligocene Depocenters In Prydz Bay, East Antarctica : A Lithostratigraphic Correlation Of Odp Sites 739, 742, And 1166, Daniel James Ciarletta

Theses, Dissertations and Culminating Projects

The Eocene-Oligocene transition (EOT) marked a profound shift in the Earth’s climate, as the global greenhouse o f the early Cenozoic gave way to ‘icehouse’ conditions, or a climatic regime influenced by the waxing and waning o f glacial ice. Antarctica was dramatically altered during this time; its formerly cool temperate ecosystems nearly obliterated by the first major episode o f continental glaciation. A record o f this transition appears to be partly preserved in approximately half a kilometer o f sediments recovered from three holes (at ODP Sites 739, 742, and 1166) bored in the continental margin at Prydz …

Summer River Water Temperature Changes In The Musconetcong River And Their Potential Impact On Aquatic Habitat, Joseph Anthony Kowalski

Theses, Dissertations and Culminating Projects

Water temperature changes in rivers can happen quickly for multiple reasons, and can drastically impact the river in many ways. The potential for temperature shifts to impact rivers is especially important in the summer, for aquatic habitats, as the warm temperatures can stress populations. This is especially true for trout populations, a temperature-sensitive fish. Since temperature is the most important factor in the growth of trout, these temperature changes can be life threatening. Therefore it is important to monitor temperatures in the Musconetcong River, classified as trout maintenance waters (Musconetcong Advisory Committee et al., 2003), because of the potential negative …

The Effects Of Changes In Population Density On Discharges For The Midwestern United States, Catherine Konieczny

Theses, Dissertations and Culminating Projects

River baseflow is the river discharge supported predominantly by groundwater, and can be greatly impacted by changes in land. Intuitively, the baseflow of a river would decrease with increased urbanization, as urbanization increases the amount of impervious surfaces, limiting the ability of precipitation to infiltrate into the ground and recharge the local groundwater. However, evidence suggests that the baseflow of rivers in urbanized areas can increase as a result of leaky subsurface water infrastructures that add water to groundwater and replenish baseflow. Another reason for the baseflow increase in urbanized watersheds is that water supply systems are over-pressurized by design …

Managing Complex Water Resource Systems For Ecological Integrity: Evaluating Tradeoffs And Uncertainty, Richard Morrison

Publications

Water resource systems often contain numerous components that are intertwined or even contradictory, such as power production, water delivery, recreation, and environmental needs. This complexity makes it difficult to holistically assess management alternatives. In addition, hydro climatic and ecological uncertainties complicate efforts to evaluate the impacts of management scenarios. We need new tools that are able to inform managers and researchers of the tradeoffs or consequences associated with flow alternatives, while also explicitly incorporating sources of uncertainty. My research addresses this limitation using two modeling approaches: stochastic system dynamics modeling and Bayesian network modeling. I developed a stochastic system dynamics …

The End Of Sustainability, Melinda Harm Benson, Robin Kundis Craig

Publications

It is time to move past the concept of sustainability. The realities of the Anthropocene warrant this conclusion. They include unprecedented and irreversible rates of human-induced biodiversity loss, exponential increases in per-capita resource consumption, and global climate change. These factors combine to create an increasing likelihood of rapid, nonlinear, social and ecological regime changes. The recent failure of the Rio +20 provides an opportunity to collectively reexamine--and ultimately move past--the concept of sustainability as an environmental goal. We must face the impossibility of defining--let alone pursuing--a goal of "sustainability" in a world characterized by such extreme complexity, radical uncertainty and …

Forest Net Primary Production Resistance Across A Gradient Of Moderate Disturbance, Ellen Goodrich-Stuart

Theses and Dissertations

The global carbon (C) balance is vulnerable to disturbances that alter terrestrial C uptake and loss. Moderate disturbances that kill or defoliate only a subset of canopy trees such as insect defoliation, drought, and age-related senescence are increasing in extent and frequency; yet, little is known about the effect of moderate disturbance on forest production and the mechanisms sustaining or supporting the recovery of the C cycle across a range of moderate disturbance severities. We used a broad plot-scale gradient of upper canopy tree mortality within a large manipulation of forest disturbance to: 1) quantify how aboveground wood net primary …

"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 …

Characterization Of Enzymatic Properties Of Maize Tps And Tpp Proteins Involved In The Trehalose Pathway, Allison C. Siekman

Department of Environmental Studies: Undergraduate Student Theses

Plant metabolism’s most important skill is its ability to perform photosynthesis, converting light energy of particular wavelengths to stored biochemical energy¹. Like many organisms, plants follow a circadian rhythm. This means that the plant’s energy cycles each day, depending on whether it is day or night. During the day, light energy strikes the plant and is used to make soluble sugars, amino acids, lipids, nucleic acid, and complex carbohydrates. Not all of these compounds are used for immediate growth; a major fraction is saved for storage². During the night, the plant uses 95% of starch, the …

Integrating Gis And Hydrology For Flood Risk Analysis, Anas B. Rabie

Theses and Dissertations

Spatial analysis using GIS was evaluated for its ability to predict the potential hazard of a flood event in the Illinois River region in the State of Illinois. The data employed in the analysis are available to the public from trusted organizations such as Illinois State Geological Survey (ISGS), and the US Geological Survey (USGS). The purposes of this study are to 1) examine the applicability of GIS spatial analysis to determine flood inundation risk, and 2) to determine how to do so with the least amount of data possible, while still producing an accurate flood inundation risk map. This …

In Situ Decomposition Of Northern Hardwood Tree Boles: Decay Rates And Nutrient Dynamics In Wood And Bark, Chris E. Johnson, Thomas G. Siccama, Ellen G. Denny, Mary Margaret Koppers, Daniel J. Vogt

Civil and Environmental Engineering - All Scholarship

The decomposition of coarse woody debris contributes to forest nutrient sustainability and carbon balances, yet few field studies have been undertaken to investigate these relationships in northern hardwood forests. We used a paired-sample approach to study the decomposition of sugar maple (Acer saccharum Marsh.), American beech (Fagus grandifolia Erhr.), and yellow birch (Betula alleghaniensis Britt.) boles at the Hubbard Brook Experimental Forest in New Hampshire. Mass loss over 16 yr followed a first-order exponential decay pattern with half-lives ranging from 4.9 to 9.4 yr in bark, and 7.3 to 10.9 yr in wood. Nitrogen and phosphorus concentrations …

Assessing Scope 3 Emissions Within A University Department: Using A Life Cycle Assessment And Supply Chain Case Studies, Celia J. Landesberg, Erin E. Brady

Geography and the Environment Capstone Projects

For this report, we conducted a small-scale life cycle assessment for the Department of Geography and the Environment. To supplement the scope of our results, we integrated case studies into our project that analyzed two commonly utilized products frequently purchased by our University: Coca-Cola PlantBottles and Hammermill Paper. The purpose of this project is to identify opportunities to reduce Scope 3 emissions associated with University purchasing habits.

While the scope of this report is limited, analysis of the department and the two case studies suggest the University should conduct a larger, more comprehensive supply chain assessment in the future to …

The Occurrence And Consequences Of Conspecific Brood Parasitism In The Prothonotary Warbler (Protonotaria Citrea), Anna Tucker

Theses and Dissertations

Brood parasites avoid costs associated with raising young by adding eggs to another individual’s clutch and providing no parental care. When conspecific brood parasitism occurs in species with high parental investment, we expect hosts to suffer costs for raising an enlarged brood. Here I describe conspecific brood parasitism (CBP) in the prothonotary warbler using maternal exclusion analyses of 333 family groups. I found that 23.4% of clutches contained at least one offspring that was not matched to the social mother and determined that parasitism seems to be an opportunistic tactic. Hosts had lower average annual reproductive success than non-hosts, but …
