Samir A. El-Swaify University of Hawaii, USA Welcome to Honolulu William J. Elliot USDA-Forest Service, USA Soil erosion researchers from around the world have helped the American David T. Favis-Mortlock Society of Agricultural Engineers SW-223 Committee organize this University of Oxford, United Kingdom special international symposium on Soil Erosion Research for the 21st Roger Funk Century to be held in Honolulu. We plan for this conference to be much Institute of Soil Landscape Research, Germany more than just a setting for presentations on state-of-the-art research. This gathering of worldwide erosion experts will also be an opportunity for William Hughey USDA-Natural Resources Conservation Service, USA reflection, challenge, vision, sharing, and setting a new course for soil erosion science. Prasanta K. Kalita University of Illinois, USA The conference has a variety of sessions that will provide all participants Peter I.A. Kinnell the opportunity to share their knowledge and ideas. The symposium Australia National University, Australia program begins with presentations and challenges from three outstanding keynote speakers on wind erosion modeling and control, water erosion Andreas Klik modeling and control, and soil erosion quantification techniques. Panel University of Agricultural Sciences, Austria sessions will facilitate discussion of these three major topics and provide John M. Laflen focus for meeting participants to discuss erosion research in small groups. Purdue University, USA Individual lecture and poster presentations should provide everyone with information on current erosion research efforts. A half-day mid-meeting John Leys Gunnedah Research Center, Australia tour and an optional post-meeting tour will provide participants the opportunity to view first-hand erosion and sedimentation problems and Manuel R. Reyes solutions under tropical conditions. North Carolina A&TState University, USA

Ramesh P. Rudra One of the goals of this erosion research symposium is to provide University of Guelph, Canada information to individuals, groups, and agencies about needed directions for soil erosion research activities and funding. The recommendations Gerd Sparovek University of Sao Paulo, Brazil from the panels and small group discussions will be summarized and provided to the meeting participants, sponsoring groups, and other Geert Sterk interested private and public organizations. Wageningen University, The Netherlands

Larry C. Wagner I know that you will want to participate in this unique and exciting USDA-Agricultural Research Service, USA symposium. I look forward to seeing you in Honolulu next January.
