This book, edited by Sara Kindon, Rachel Pain, and Mike Kesby, provides a comprehensive review of Participatory Action Research (PAR) as part of Routledge’s Studies in Human Geography. It is useful beyond the discipline, offering a timely overview of PAR's current status and practical applications. The book is structured into three main sections, each beginning and ending with reflections that bracket the "Action" section. It traces the disciplinary and scholarly origins of PAR, discusses the ideological concept behind participatory research, and addresses the shift from focusing solely on scientific outcomes to including process as part of research outcomes. The first section provides an overview of PAR methods, highlighting the various schools of PAR and their theoretical sources. It also emphasizes the importance of reflecting on unexpected and often invisible results, such as power differentials and hierarchies, and the potential for coercion. The concept of empowerment is critically discussed, noting that it is more productive to view power and empowerment as entangled. The section also addresses the challenges of contributing to theory and maintaining confidentiality in academic ethics boards. The second section focuses on action, featuring case studies from diverse settings, including New England fisheries, Peruvian national parks, and communities in Zimbabwe and Kenya. These case studies illustrate the application of various PAR methods, such as body mapping, peer strategies, participatory art, diagramming, theatre, cartography, social auditing, and photovoice. The third section emphasizes that PAR is a process for learning for all participants, particularly researchers. It highlights the importance of representing and communicating PAR effectively, advising researchers to ensure that language and potential stereotyping are carefully checked in publications and other dissemination channels. Overall, the book contributes to a deeper understanding of the theory and practice of PAR, making it a valuable textbook and a tool for experienced researchers to review and expand their approach.This book, edited by Sara Kindon, Rachel Pain, and Mike Kesby, provides a comprehensive review of Participatory Action Research (PAR) as part of Routledge’s Studies in Human Geography.
