Spatial Assessment of Cumulative Vehicle Use Impacts for Sustainable Military Land Carrying Capacity and Environment
Guangxing Wang, PI, US Army Construction Engineering Research Laboratory (CERL)

In the United States, the Army requires various training programs. These military activities inevitably disturb ground cover, damage plants, increase soil erosion, degrade habitats, fragment landscapes, and lead to natural resources and land condition degradation. The degraded land condition in turn limits military land carrying capacity. Thus, the land managers need information on land conditions and their history for both sustainable military land carrying capacity and environment and there is a strong need for methodology development to model, assess, and predict the land conditions and cumulative military training impacts.

The objective of this project is to develop a set of new methodologies that are designed to mitigate environmental effects of military training on landscapes and at the same time to sustain military land carrying capacity. These methodologies include a method to select and integrate spatial metrics so that to derive an integrated indicator that can be used to comprehensively assess environmental quality; a method for determining the threshold values for critical environmental factors; a method to reproduce spatial patterns and dynamics of cumulative vehicle use impacts; and a prediction model of land condition based on the relationship of land condition dynamics with military training strength. These methods will be developed by combining GIS, remote sensing, and spatial simulation algorithms. This project is funded by the U.S. Army Construction Engineering Research Laboratory (CERL).


Development of 21st Century Precipitation Scenarios Using Probabilistic Downscaling Techniques
Justin Schoof, PI and Sara Pryor, Indiana University

There is currently great interest in modeling the evolution of the climate system for approaching decades.  In this study, the focus is on precipitation, and specifically, on development of novel techniques for extraction of local-scale, probabilistic information from coarse resolution climate models.  The model archive assembled for the 2007 reports of the Intergovernmental Panel on Climate Change provides access to a unprecedented array of climate model simulations for the 21st Century.  The primary objective of the research is to develop future precipitation scenarios for point locations throughout the contiguous USA.  The scenarios will focus on probability distribution parameters so that end users can use the projections for a range of impact related studies.  This project is funded by the Geography and Regional Sciences Program of the National Science Foundation.

Connect SI GIS Mapping Component
Tonny J. Oyana, PI

Daily Egyptian article:  "Mapping Southern Illinois"

The overall objective, in our GIS mapping component of this very big research project, is to support Connect SI in their 20-county effort, which aims at collaboratively enhancing the economic and community development efforts throughout Southern Illinois using greater Internet access and bandwidth to communicate regionally and globally. We are specifically tasked with building a very large GIS database for Connect SI that contains both baseline and thematic maps; and developing an Internet Map Service based on this GIS database which will serve as an interactive web application showing important baseline or thematic layers in the study region.

Connect SI project isn’t just about broadband internet access. It is about improving the quality of the lives of Southern Illinoisans by changing the way we work, live, and communicate with the world. This project will affect many sectors of life in the region. Healthcare delivery, business and industry, education and training, government, agriculture, – even our own homes – can benefit from greater accessibility and visibility through a successful Connect SI project. Greater efficiency and access to broadband Internet services can mean more profitability for those who wisely use the increased availability of greater bandwidth. For additional information contact Dr. Tonny J. Oyana or Mr. Rex Duncan, Executive Director, SIUC President’s Office.

Introduction to Financial Benchmarking for Small Drinking Water Systems
Ben Dziegielewski, Roger Beck (emeritus), and T. Bik, 2006, Midwest Technology Assistance Center

In the year 2000, the Midwest Technology Assistance Center (MTAC) funded the Benchmark Investigation of Small Public Water System Economics (pdf). One finding of this study was that while small drinking water managers are very interested in improving the financial performance of their systems, they lack access to information about effective business techniques such as benchmarking, can be used to assess and improve the performance of their systems. MTAC subsequently funded the development of this self-instruction training module.

The training module provides an outline of the what, why, and how of financial benchmarking for small systems, and takes less than one hour to complete. It also includes links to other benchmarking resources.

The Self-Instruction Training Module is available in both Microsoft PowerPoint and Adobe Portable Document Format and can be downloaded or viewed online. The module works best if downloaded to your computer. Simply right click on the hypertext of the format of your choice and download the document to your computer using the “Save Target As …” option.

Good Growing: Why Organic Farming Works
Leslie Duram, University of Nebraska Press, ISBN 0-8032-6648-0, 250 pages.

Over the past decade, organic products have become the fastest growing sector of agriculture, with an annual increase of at least 20 percent. This book explains why organic production and consumption have seen such phenomenal growth in recent years­and, even more important, why they should. A clear-eyed, close-up look at the compelling reasons for organic farming and the methods that make it work, Good Growing begins with a frank account of the problems with conventional industrial agriculture­the pesticide use, pollution, and corporate control that have undermined public health and devastated rural towns and family farms

In-depth interviews with working organic farmers from across the country bring to life the facts and figures that Leslie Duram sets out in her extensive overview of the realities of organic farming today. Farmers with very different operations in California, Colorado, Illinois, Florida, and upstate New York give us an intimate understanding of the ecological, social, economic, and personal factors that shape their farming experiences. With its comprehensive view of the status of farming and its compelling portraits of organic farmers, Good Growing is, finally, a work of scientific advocacy describing a course of action, based on the best research available, to improve the health of agriculture in our day.

Food For Thought
Spring 2005 issue of Perspectives: Research and Creative Activities at SIUC Geographer Leslie Duram looks at the contributions organic farmers make to society and the issues they face.

Virtual Watershed: Agricultural Landscape Evolution in an Adaptive Management Framework
Christopher Lant, Girmay Misgna (Southern Illinois University Carbondale), Raja Sengupta (McGill University), and George Malanson (University of Iowa), together with SIUC Agricultural Economists Steven Kraft and Jeffrey Beaulieu and Environmental Engineer John Nicklow have received $450,000 in funding from the National Science Foundation for their project “Virtual Watershed: Agricultural Landscape Evolution in an Adaptive Management Framework.” Funded from the Biocomplexity in the Environment: Coupled Natural and Human Systems program, the 3.5 year Virtual Watershed project will build a spatial decision support system of land use patterns in agricultural watersheds using GIS, agent-based modeling, environmental simulation modeling and evolutionary algorithms. The project will focus on how land use decisions are guided by variable economic, policy and environmental circumstances and how the resulting land use patterns generate agricultural goods and ecosystem services such as carbon sequestration, water quality, and flood retention in an manner that may be self-organizing. The visually improved Virtual Watershed model will be valuable in educational and environmental and agricultural policy-making settings.

Analysis of Water Use Trends in the United States: 1950 – 1995
Ben Dziegielewski, Professor, Department of Geography; Subhash C. Sharma, Professor, Department of Economics; Thomas J. Bik, Researcher, Department of Geography; Heru Margono, Graduate Assistant, Department of Economics; Xiaoying Yang, Graduate Assistant, Department of Geography. USGS-funded research project: Analysis of Water Use Trends in the United States: 1950 – 1995, 1999 USGS National Competitive Grants Program, Grant No. 99HQGR0222, Subgrant No. 00-312.

Analysis of Water Use Trends in the United States: 1950 – 1995 Website

Improved information about water withdrawals and uses in specific geographical regions and a basic understanding of the factors that influence water use are a necessary requirement for sound water resources management. The USGS National Water-Use Information Program (NWUIP) has collected and published an extensive inventory of water use information since 1950. This information has provided a basis for the development and evaluation of national water policies as well as regional and local plans for the development and use of water resources. It also offers an excellent opportunity for examining and explaining historical trends in water use.
