The Chernobyl Disaster : Reflection After 25 Years = 切爾諾貝爾核災難25年後的反思, Valentin Yakushik

South South Forum 南南論壇

The adverse technogenic impact of industrial accidents that have gripped the world in recent decades definitely testifies to the problem-ridden character of contemporary economic and technological development. This is especially evident on the example of nuclear industry, which proved to be a source of dangerous pollution in case of potential (and real) catastrophes, as recently borne out by the Fukushima disaster. In this regard, the issues of Chernobyl disaster once again become the part of the discourse centered on the analysis of global nuclear industry problems. Likewise, current situation in Ukraine demands deeper investigation of the problems of technological development, …

Randomization Tests For Quantifying Species Importance To Ecosystem Function, Nicholas J. Gotelli, Werner Ulrich, Fernando T. Maestre

College of Arts and Sciences Faculty Publications

1. Quantifying the contribution of different species to ecosystem function is an important challenge. We introduce simple randomization tests (and software) for quantifying the average effect of species on ecosystem variables measured in multiple plots with and without the presence of a particular species. These randomization tests formalize the analysis of uncontrolled 'natural experiments' and quantify species effects in standardized deviation units. 2.We tested the method with data on ecosystem function in biological soil crust assemblages of lichens in semi-arid gypsum outcrops in central Spain. In sixty-three 50cm×50cm sample plots, we measured the presence and percentage cover of 17 species …

Ecological Revival And Sustainable Living In The Tropical Dry Evergreen Forest Of Tamil Nadu: A Measurement Of Residential Perception In Sadhana Forest, Elizabeth Collette Mcguire

Department of Environmental Studies: Undergraduate Student Theses

Since 1970, the role and function of the U.S. Environmental Protection Agency (EPA) has been to promote environmental quality and to form strategies for carrying out environmental policy¹. The EPA has committed to sustainability as the next level of environmental protection. The agency states that sustainability calls for policies and strategies that meet society’s present needs without compromising the ability of future generations to meet their own needs². Presently, society’s requirements have resulted in natural resource exploitation and population distention- projected to reach 10 billion people within two human generations³. These paired occurrences are …

The Limits To Prediction In Ecological Systems, Brian Beckage, Louis J. Gross, Stuart Kauffman

College of Agriculture and Life Sciences Faculty Publications

Predicting the future trajectories of ecological systems is increasingly important as the magnitude of anthropogenic perturbation of the earth systems grows.We distinguish between two types of predictability: the intrinsic or theoretical predictability of a system and the realized predictability that is achieved using available models and parameterizations. We contend that there are strong limits on the intrinsic predictability of ecological systems that arise from inherent characteristics of biological systems. While the realized predictability of ecological systems can be limited by process and parameter misspecification or uncertainty, we argue that the intrinsic predictability of ecological systems is widely and strongly limited …

Heating Up The Forest: Open-Top Chamber Warming Manipulation Of Arthropod Communities At Harvard And Duke Forests, Shannon L. Pelini, Francis P. Bowles, Aaron M. Ellison, Nicholas J. Gotelli, Nathan J. Sanders, Robert R. Dunn

College of Arts and Sciences Faculty Publications

1.Recent observations indicate that climatic change is altering biodiversity, and models suggest that the consequences of climate change will differ across latitude. However, long-term experimental field manipulations that directly test the predictions about organisms' responses to climate change across latitude are lacking. Such experiments could provide a more mechanistic understanding of the consequences of climate change on ecological communities and subsequent changes in ecosystem processes, facilitating better predictions of the effects of future climate change. 2.This field experiment uses octagonal, 5-m-diameter (c.22m 3) open-top chambers to simulate warming at northern (Harvard Forest, Massachusetts) and southern (Duke Forest, North Carolina) hardwood …

The High Costs Of Conserving Southeast Asia's Lowland Rainforests, Brendan Fisher, David P. Edwards, Xingli Giam, David S. Wilcove

Rubenstein School of Environment and Natural Resources Faculty Publications

Mechanisms that mitigate greenhouse-gas emissions via forest conservation have been portrayed as a cost-effective approach that can also protect biodiversity and vital ecosystem services. However, the costs of conservation - including opportunity costs - are spatially heterogeneous across the globe. The lowland rainforests of Southeast Asia represent a unique nexus of large carbon stores, imperiled biodiversity, large stores of timber, and high potential for conversion to oil-palm plantations, making this region one where understanding the costs of conservation is critical. Previous studies have underestimated the gap between conservation costs and conversion benefits in Southeast Asia. Using detailed logging records, cost …

Subsurface Characterization Of Groundwater Contaminated By Landfill Leachate Using Microbial Community Profile Data And A Nonparametric Decision-Making Process, Andrea R. Pearce, Donna M. Rizzo, Paula J. Mouser

College of Engineering and Mathematical Sciences Faculty Publications

Microbial biodiversity in groundwater and soil presents a unique opportunity for improving characterization and monitoring at sites with multiple contaminants, yet few computational methods use or incorporate these data because of their high dimensionality and variability. We present a systematic, nonparametric decision-making methodology to help characterize a water quality gradient in leachate-contaminated groundwater using only microbiological data for input. The data-driven methodology is based on clustering a set of molecular genetic-based microbial community profiles. Microbes were sampled from groundwater monitoring wells located within and around an aquifer contaminated with landfill leachate. We modified a self-organizing map (SOM) to weight the …

Governance Informatics: Managing The Performance Of Inter-Organizational Governance Networks, Christopher Koliba, Asim Zia, Brian H.Y. Lee

College of Agriculture and Life Sciences Faculty Publications

This article introduces an informatics approach to managing the performance of inter-organizational governance networks that are designed to create, implement and evaluate public policies and the range of activities undertaken by practicing public administrators. We label this type of information flow process management "governance informatics" and lay out a range of theoretical constructs that may be used to collect, categorize, and analyze performance in inter-organizational governance networks. We discuss how governance informatics may be able to assess and re-design the accountability and transparency regimes of information flows in inter-organizational governance networks. The integration of a governance informatics-driven performance management system …

Understanding Bioprospecting: Can Indigenous Populations Benefit From The Search For Pharmaceuticals In Areas Of High Biodiversity, Emily Schwindt

Department of Environmental Studies: Undergraduate Student Theses

Bioprospecting is a controversial issue, and anthropologists and other scientists are quick to take sides. The idea of large corporations pumping money into conservation and development programs, while developing what could be the latest life-saving drug simply sounds too good to be true, and often times is. However, if all parties work together and proceed with caution, these benefits could become more than a fantasy. Looking at case studies from Costa Rica, India, South Africa and Panama this paper attempts to find patterns among successful bioprospecting agreements and note shortcomings and identify risks. This information will be used to suggest …

The study was completed at Norris Elementary School where the students have access to the “Norris Forest” which is a planted forest with a walk way through the trees. Some of the trees are labeled for the students to identify and others are not. A graph of the unlabelled trees has been included for the students or the teachers to use.

This project incorporates activities that will engage the students in order to teach …

Parks And Obesity In Rural And Urban Nebraska, Michaela S. Wolf

Department of Environmental Studies: Undergraduate Student Theses

In order to better understand the role community design plays in obesity rates, this project studies a potential relationship between distance of parks from homes and obesity rates in four Nebraska counties. Park use may contribute to important health benefits, such as reducing risk of obesity by increasing physical activity levels. There are limitations to park use, such as crime rates and facility upkeep that are important to understand so that they might be managed and communities can reap greater benefits from their parks, including better fitness. This study examines park distance from homes as a potential limiting factor to …

Keynote Address: Community Health In Las Vegas, Camila H. Alvarez

Festival of Communities: UG Symposium (Posters)

New Urbanists present both a theory for strong community development and an architectural planning program for moving towards sustainable urban environments. They argue neighborhoods should be compact, pedestrian-friendly, with mixed-usage of housing and activities, and available public spaces. These design elements foster and encourage social interaction among residents which creates and enforces neighborhood community. I tested New Urbanism Theory by performing ethnographic fieldwork to assess the quality of neighborhoods in Las Vegas. Then I compared neighborhood qualities to residents’ responses to their neighborhood, neighbors, and quality of life from the Las Vegas Metropolitan Area Social Survey. My results confirmed New …

The Impact Of Qmm On Social Relations In Fort-Dauphin, Christopher B. Collier

Independent Study Project (ISP) Collection

My interest in this subject began with a general desire to understand how Malagasy society adapts to “outsiders.” We learned throughout the semester about the various external forces that have shaped the culture of the island since the arrival of the first people here thousands of years ago. At first, my ideas were focused more on the experiences of people immigrating to Madagascar. I observed very particular patterns: immigrants of certain ethnicities fill specific socioeconomic niches in specific geographic areas, and with varying reception from the Malagasy community.

I came to realize, however, that similar patterns take place even between …

Seawalls In Samoa: A Look At Their Environmental, Social And Economic Implications, Sawyer Lawson

Independent Study Project (ISP) Collection

This study concerns the environmental, economic and social implications of seawalls in Samoa. Information for this study was gathered using a combination of secondary sources and primary sources including interviews, surveys and participant observation. Given the cultural and economic importance of Samoa’s coastline and the fact that seawalls, which already occupy much of Samoa’s coast, are becoming more abundant, it is important to understand the implications of building them. The researcher found that partially due to climate change and sand mining, Samoa’s coastline has become increasingly threatened by erosion and coastal retreat. Seawalls are in many cases the fastest and …

Yongzhi Village: An Example For Sustainable Tourism And Development In Deqin County, Kiersten Brown

Independent Study Project (ISP) Collection

Nestled beneath misty mountain peaks, among the Salween, Mekong, and Yangtze rivers, a beautiful Tibetan village lies. Alongside low-lying mountain creeks and waterfalls this village is in Deqin County of Yunnan’s Deqin Tibetan Autonomous Prefecture (Deqin TAP). The Deqin TAP is the most Northwest prefecture of Yunnan. Deqin boasts that 33% of its population is comprised of the dominant minority group, Tibetans. Deqin prefecture is comprised of three counties, Shangrila County, Deqin County, and Weixi County. Deqin County is mostly comprised of small Tibetan towns and villages like Yongzhi. About 100 families inhabit Yongzhi. The village is placed right along …

Cross-Scale Value Trade-Offs In Managing Social-Ecological Systems: The Politics Of Scale In Ruaha National Park, Tanzania, Asim Zia, Paul Hirsch, Alexander Songorwa, David R. Mutekanga, Sheila O'Connor, Thomas Mcshane, Peter Brosius, Bryan Norton

College of Agriculture and Life Sciences Faculty Publications

Management of social-ecological systems takes place amidst complex governance processes and cross-scale institutional arrangements that are mediated through politics of scale. Each management scenario generates distinct cross-scale trade-offs in the distribution of pluralistic values. This study explores the hypothesis that conservation-oriented management scenarios generate higher value for international and national scale social organizations, whereas mixed or more balanced management scenarios generate higher value for local scale social organizations. This hypothesis is explored in the management context of Ruaha National Park (RNP), Tanzania, especially the 2006 expansion of RNP that led to the eviction of many pastoralists and farmers. Five management …

Scientific Instruments For Climate Change Adaptation: Estimating And Optimizing The Efficiency Of Ecosystem Service Provision, Ferdinando Villa, Ken Bagstad, Gary Johnson, Brian Voigt

Rubenstein School of Environment and Natural Resources Faculty Publications

Adaptation to the consequences of climate change can depend on efficient use of ecosystem services (ES), i.e. a better use of natural services through management of the way in which they are delivered to society. While much discussion focuses on reducing consumption and increasing production of services, a lack of scientific instruments has so far prevented other mechanisms to improve ecosystem services efficiency from being addressed systematically as an adaptation strategy. This paper describes new methodologies for assessing ecosystem services and quantifying their values to humans, highlighting the role of ecosystem service flow analysis in optimizing the efficiency of ES …

Incorporating Systems Thinking And Sustainability Within Civil And Environmental Engineering Curricula At Uvm, Nancy J. Hayden, Donna M. Rizzo, Mandar M. Dewoolkar, Lalita Oka, Maureen Neumann

College of Engineering and Mathematical Sciences Faculty Publications

As part of an NSF Department Level Reform (DLR) grant, the civil and environmental engineering programs at the University of Vermont (UVM) incorporated systems thinking and a systems approach to engineering problem solving within their programs. A systems thinking approach regards social, environmental and economic factors as necessary components of the problem solution. Because it is a whole systems approach it also encompasses sustainability. We have integrated systems thinking in the following ways; 1) new material has been included into key courses (e.g. the first-year introductory and senior design courses), 2) a sequence of three related environmental and transportation systems …
