The Project is currently approaching its mid term phase, and is organizing an international workshop on methodology exchange in land use planning (June 15-19, 1998 at Can Tho City, Mekong Delta, Vietnam). During 1997, much effort has been put into data collection and developing novel methodologies for exploring land use options at the regional (subnational) level; the various aspects of work being carried out have not yet been presented as a whole. It is timely and appropriate now to publish some of the ideas, approaches, and preliminary results and convey this information to specialized institutions, all collaborators in the Project, donors and clients, and individual subject matter specialists.
