In this book, eleven original accounts by researchers from a variety of disciplines (sociology, process engineering, water science, computer modeling, anthropology, hydrogeology, agronomy, ecology) illustrate concrete ways of practicing interdisciplinarity with a view to building committed research on water in society. In an interdisciplinary world, they testify to the happy or uncomfortable situations experienced by researchers, and the arrangements deployed to deal with the unexpected aspects of such practices. The book suggests new ways of working with water, and proposes to make intelligible the relationships that societies maintain with it, around major issues: pollution, groundwater salinization, ecological restoration, technological optimism, in different regions of the world. Beyond the singularity of each story, these accounts underline the transversal stakes of interdisciplinary practice in both individual and collective experiences: the researcher's identity and commitment to society, the aims of research, and reciprocal learning, conducive to overcoming disciplinary boundaries. This book is aimed in particular at researchers and students undertaking or considering interdisciplinary research.
