Public risk management covers a wide range of issues, organisational methods and actions relating to the State and local authorities. It differs from crisis management, which is required once the risks have occurred; here, it is necessary to implement mitigation measures and reaction capabilities in advance. Public authorities are required to manage many “external” risks, i.e. to prevent them from occurring and protect the public against their effects, but they also need to protect themselves against “internal” risks; for example, by ensuring the continuity of their actions towards the public. The report published today sets out to analyse the governance of public risk management, the processes it uses and the conditions required to enable it to be tailored to ever-changing risks.
