Emerging risks in the 21st century - An agenda for action Risk assessment
This chapter focuses on risk assessment, a scientific process that aims to identify and evaluate each step in the evolution of a hazard, from its origins to its final consequences for the system in question. The process can take a variety of forms depending on the nature of the hazard, the system involved, and the context in which the risk evolves. In past decades a myriad of risk assessment procedures have been developed. Those that are briefly reviewed in this chapter include hazard and risk assessment for natural disasters, using tools ranging from statistical analysis to catastrophe models; toxicity assessment for hazardous substances, based on estimated dose-response relationships; and safety assessments for highly structured systems such as plants or aeroplanes.
