This book draws on the experience of leading risk researchers and practitioners to examine risk communication in research and in practice and to explore how to make it more effective in future. Beginning with reflections on the evolution of risk communication, the book presents seminal papers from the last 25 years of risk communication along with newly written commentaries by the original authors. The following sections are themed around key issues: credibility and trust; risk communication design; and deliberation and decision. In each specially commissioned chapter, the authors reflect on the theoretical and applied underpinnings of their best projects and comment on how their approach could be used effectively by others. Building upon each other, the chapters will provoke new discussion and action around a discipline which many feel is neither meeting important needs in practice, nor living up to its potential in research. Through a more careful examination of the work already done in risk communication the book will help develop better, more reflective practice for the future.
