Book excerpt: Through illustrated case studies and conceptual re-framings, this volume showcases ongoing transformations in public space, and its relationship to the public realm more broadly in the world’s most populous urban megaregion—the Greater Bay Area of southeastern China—projected to reach eighty million inhabitants by the year 2025. This book assembles diverse approaches to interrogating the forms of public space and the public realm that are emerging in the context of this region’s rapid urban development in the last forty years, bringing together authors from urbanism, architecture, planning, sociology, anthropology and politics to examine innovative ways of framing and conceptualizing public space in/of the Greater Bay Area. The blend of authors’ first-hand practical experiences has created a unique cross-disciplinary book that employs public space to frame issues of planning, political control, social inclusion, participation, learning/education and appropriation in the production of everyday urbanism. In the context of the Greater Bay Area, such spaces and practices also present opportunities for reconfiguring design-driven urban practice beyond traditional interventions manifested by the design of physical objects and public amenities to the design of new social protocols, processes, infrastructures and capabilities. This is a captivating new dimension of urbanism and critical urban practice and will be of interest to academics, students and practitioners interested in urbanization in China.
