This is a very interesting and useful volume that represents an important contribution to the field. the book integrates both natural and social sciences and provides useful reviews of the state of the art in a wide variety of areas of risk assessment and management. chapters that examine different aspects of risk assessment are very valuable and deserve to be widely read. It will be of interest to both the research and the practitioner communities. (David Petley, Mountain Research and Development, Vol. 35 (2), May, 2015)
