There is an emerging consensus concerning a new strategic mode for spatial policy. In the past, planning resulted in zoned land uses characterised by a rigid separation of housing from leisure and workplaces. This strongly sectoral approach is breaking down under the pressure of environmental problems, technological innovations, and a societal demand for a higher quality of life. Spatial planning will increasingly involve broad framework policies at the national level, and strong partnerships at the local and regional level. This volume is based on two international seminars oranised by the OECD and the National Land Agency, Japan.
