This book brings together the world's leading risk researchers and practitioners to examine risk communication in research and in practice and explore how to make it more effective in future. Beginning with the evolution of risk communication, the book presents the seminal papers on risk communication of the last twenty-five years along with newly written commentaries by the original authors. The authors reflect on the theoretical and applied underpinnings of their best projects and explore how their approaches could best be used by others. By carefully examining the work already done in risk communication, the book shows the way to better, more reflective practice for the future.
