The meeting will be held in dedicated, full service facilities at The Banff Centre for Conferences in Banff, Alberta, Canada, September 2-8, 2000. Self-explanatory abstracts in English should be 1-2 pages in length and must include title, author(s), institutional affiliation(s), explanation of completed work to be described, and 5-10 author-assigned key words. Clear relevance must be shown to predictive, numerical modeling approaches to environmental problem solving. A special conference theme will be human-environment interactions, and the role that GIS and modeling have in their improved understanding and prediction. The forum will retain its cross-disciplinary, pan-scientific, and problem solving emphases consistent with a concern for better integrated understanding of complex whole systems, their integrity and sustained functioning, and particularly (but not exclusively) their interactions with human activity. Spatial, statistical, temporal, and other methodological considerations are expected to be given balanced treatment with issues of science theory, new data sources and sensors, computing technologies, and application techniques.
