This book reports on a large research project on community regeneration, which integrated the spatial, social, economic and organizational factors with the dimensions of sustainability, resilience and participation. Upon providing a detailed review on concepts of community and urban regeneration, it analyses a set of successful case studies from 30 European cities, which were selected by the authors from different rankings and awards. Fifty-seven key performance indicators and the results of self-assessment questionnaires are here introduced to allow a comparative study of best practices and eventually to outline 20 guidelines and 100 strategic actions for future community regeneration projects. All in all, this book offers extensive information and a source of inspiration for urban planners, economists, sociologists, public administrators, stakeholders and all those involved in the development and management of sustainable cities.
