This book draws on the recent development in deliberative planning theory and decision support systems, the synthesis of which has resulted in an innovative approach to supporting the communicative processes in urban regeneration through unique methodologies. A range of tools and methods are introduced with real-world applications in Japan and elsewhere. This book not only presents a catalogue of available toolkits to practitioners, but also offers new insight into how the theoretical debate on deliberative planning could inform the practice of urban regeneration. It also presents a catalogue of available tools and unique methodologies with real-world applications. The cases are drawn from such fields as community development, urban hazard mitigation, transportation policies, and participatory urban design, both in Japan and elsewhere. Issues are raised in relation to each case, ranging from problem structuring to conflict management and consensus building in typically complex and heterogeneous urban communities. The book is ideal for those researchers and postgraduate students who have an interest in planning support methodologies with the backgrounds of information systems, decision sciences, or other related disciplines, who are interested in planning support methodologies. Practitioners including policy-makers and planners who are seeking an alternative approach to urban regeneration will also benefit from this book by learning from the comparable experience with reflective discussions included on their implications.
