“Glowa-Danube ( is an interdisciplinary project that aims to develop integrated strategies and tools for water and land use management in the upper Danube catchment (Germany, Austria ~77,000km2). The project is one of five within the Glowa research program ( dealing with Global Change effects on the water cycle in six meso-scale catchments (up to 100,000km2) in Central Europe, West Africa and the Middle East. In the Glowa-Danube project, 16 natural science and socio-economic simulation models are integrated in the coupled simulation system Danubia. This article describes the underlying concept and implementation of WaterSupply, a multiactor-based model of the water supply sector with a focus on water resource utilization and distribution of individual water supply companies. Within Danubia, WaterSupply represents the link between water supply and demand, where the former is simulated by a groundwater and a surface water model and the latter by water consumption models of four different sectors (domestic, industrial, agricultural and tourism). WaterSupply interprets the quantitative state of water resources for defined spatial and temporal units according to sustainability requirements and assesses the state of resources in relation to present water supply schemes and the dynamics of user demand. WaterSupply then seeks both to optimize the resource use of supply companies and to identify critical regions for which further adaptation of the water supply scheme will become necessary under changing climatic conditions. In this article, a brief description of the Glowa-Danube project and the integrated simulation system Danubia is followed by a short presentation of the DeepActor framework, which provides a common conceptual and technical basis for the socio-economic simulation models of Glowa-Danube. The main body of the article is devoted to the concept, the implementation and simulation results of WaterSupply. Results from different scenario calculations demonstrate the capabilities and the potential fields of application of the model.”

Climate Projection Data Download: Characteristically Generated Monthly Climate Data using Downscaled Climate Model Data from the IPCC’s Fourth Assessment

“This dataset was generated by a generalized downscaling and data generation method that takes the outputs of a General Circulation Model and allows the stochastic generation of daily weather data that are to some extent characteristic of future climatologies. Such data can then be used to drive any impacts model that requires daily (or otherwise aggregated) weather data.

A subset of the climate models and scenario runs carried out for 2007’s Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) for two time slices (2030 and 2050) was used in this process.”

An Assessment of Land Conservation Patterns in Maine Based on Spatial Analysis of Ecological and Socioeconomic Indicators

Environmental Management, Published Online 06 April 2010

“Given the nature of modern conservation acquisitions, which often result from gifts and opportunistic purchases of full or partial property rights, there is a risk that the resulting mosaic of conserved resources may not represent a coherent set of public values and benefits. With different public and private entities engaged in land conservation, one would further expect that each organization would apply separate goals and criteria to the selection and acquisition of its conservation portfolio. This set of circumstances raises an important question: what is the aggregate outcome of this land conservation process? Retrospective assessments provide a means of reviewing cumulative historical decisions and elucidating lessons for improving future conservation strategies. This study used GIS-based spatial analysis to examine the relationships of private and public conservation lands in Maine to a variety of landscape metrics in order to determine the degree to which these lands represent core ecological and socioeconomic values that are meaningful to a wide cross-section of citizens. Results revealed that the gains of past conservation efforts in Maine are counter-balanced to some extent by apparent gaps in the existing fabric of conservation holdings. Conservation lands capture a representative sample of diverse habitat, provide a large measure of protection for multiple conservation values and indicators, and offer an unusual mix of outdoor recreational opportunities for residents and visitors alike. Yet, the majority of parcels are relatively small and isolated, and thus do not provide contiguous habitat blocks that offset ongoing processes of landscape fragmentation. Furthermore, the majority of area associated with many of the ecological metrics examined in this report is located outside the boundaries of current conservation holdings. The under-represented metrics identified in this investigation can be viewed as potential targets for new strategic conservation initiatives.”

Scientists to Speak on Global Environmental Issues

Redlands Forum Presents Woods Hole Research Center Scientists William Brown and Josef Kellndorfer

From mapping the Amazon River basin to promoting global climate change policy, scientists at the Woods Hole Research Center (the Center) are focused on keeping Planet Earth healthy. The next Redlands Forum event will feature William Brown, Ph.D., president and CEO of the Center, who will describe how the Massachusetts-based institute is working to help protect the global environment. His colleague, Josef Kellndorfer, Ph.D., associate scientist at the Center, will also speak. The presentations will take place in Redlands at the ESRI Conference Center, 380 New York Street, on Wednesday, May 19, at 5:30 p.m.

Brown will give an overview of the Center’s global activities with the talk Woods Hole Research Center: Science, Policy, and Education for a Healthy Planet. Then, Kellndorfer will drill down to describe a research project that uses satellite imagery technology to map the world’s forests. His presentation has the intriguing title Shooting with the Radar Gun: Another Radiological Tool to Diagnose and Monitor Patient Earth.

“Our planet’s climate and ecosystems are changing, and the scientists at the Center are leading authorities in understanding the causes and consequences of this as well as offering solutions that foster a healthy planet,” said Brown. With projects in the Amazon, the Arctic, Africa, Russia, Alaska, Canada, and New England, the Center collaborates with partners ranging from local nongovernmental organizations and research centers to national governments and the United Nations. Brown’s talk will include examples of the Center’s work around the globe.

Brown joined the Center in February 2010 and previously held posts as president and CEO of the Academy of Natural Sciences in Philadelphia, Pennsylvania, the nation’s oldest natural history museum, and as Department of the Interior science advisor during the Clinton administration. He also concurrently serves as chairman of the Global Heritage Fund, president of the Natural Science Collections Alliance, and a trustee of the Academy of Natural Sciences.

Kellndorfer’s research focuses on the monitoring and assessment of terrestrial and aquatic ecosystems. Using geographic information systems (GIS) and remote sensing, he studies land use, land cover, and climate change on a regional and global scale. Before joining the Center, he was an assistant research scientist in the Department of Electrical Engineering and Computer Science at the University of Michigan.

After May 19, the next Redlands Forum event will be a talk on recent projects and legislation affecting both Redlands and California open spaces, which will be presented by Pete Dangermond, president of The Dangermond Group. It will take place Wednesday, June 16, 2010, at 5:30 p.m.

Redlands Forum events are sponsored by ESRI and the University of Redlands through the university’s Town & Gown organization. Admission to both of these events is free. To guarantee seating, attendees should register via the Internet at or by calling 909-748-8011.

Watershed-Scale Dynamics of Tennessee Farmland Enrollment in the Conservation Reserve Program: Implications for Environmental Extension

Journal of Extension, April 2010, Volume 48, Number 2

Christopher A. Bridges

“Increased national focus on environmental quality requires Extension professionals to evaluate conservation policies and adapt outreach strategies accordingly. This case study applies spatial analysis techniques to evaluate watershed-scale changes in Tennessee farmland enrolled in the Conservation Reserve Program 1997-2007, focusing on areas that may contribute to stream quality impairment. Results indicate that cumulative enrollment in the program has decreased significantly less in watersheds targeted by interagency outreach efforts than in the remainder of the state. Integration of geospatial technologies into cooperative educational programs that complement watershed restoration strategies may represent an emerging opportunity for natural resources Extension.”
