This book concentrates exclusively on the dialogic turn in the governance of science and the environment. The starting point for this book is the dialogic turn in the production and communication of knowledge in which practices claiming to be based on principles of dialogue and participation have spread across diverse social fields. As in other fields of social practice in the dialogic turn, the model of communication underpinning science and environmental governance is dialogue in which scientists and citizens engage in mutual learning on the basis of the different knowledge forms that they bring with them. The official aim is to involve citizens in processes of decision-making on scientific and environmental issues, including issues relating to the built environment such as urban planning. The attempt in this book has been made to build bridges across the fields of science and technology studies, environmental studies and media and communication studies in order to provide theoretically informed and empirically rich accounts of how citizen voices are articulated, invoked, heard, marginalised or silenced in science and environment communication.
