A risk conundrum can be viewed as a risk that poses major issues in assessment, and whose management is not easily engaged. Such perplexing problems can either paralyze or badly delay risk analysis and directions for progression. Rather than simply focusing on the progress in risk analysis that has already been made, it is crucial to consider what has been learnt about these seemingly unmanageable problems and how best to move forward. Risk Conundrums seeks to answer this question by bringing together a range of key thinkers in the field to explore key issues such as risk communication, uncertainty, social trust, indicators and metrics, and risk management, drawing upon case study examples including natural disasters, terrorism, and energy transitions. The initial chapters address risk conundrums, their properties, and the challenges they pose. The book then turns to a greater emphasis on systemic and regional risk conundrums. Finally, it considers how risk management can be changed to address these unsolvable conundrums. Alternative pathways are defined and scrutinized and predictions for future developments set out. This book will be of great interest to students and scholars of risk governance, environmental policy, and sustainable development.
