Mitigation is an English word that is not easily translated for each language and is not used in a uniform manner. Within the MiSRaR and PRISMA projects mitigation is defined as “risk reduction by reducing the probability and/or impact of a hazard and/or the vulnerability of the society.” In other words, mitigation includes all forms of risk reduction for the various elements of the concept of risk. In the experience of the partners the distinction between risk and crisis management is not absolute. Preparation measures for specific risks (anticipation), such as spatial planning to ensure access for emergency services or evacuation possibilities, can also be interpreted as preventive effect reduction or vulnerability reduction.
