Unifying and Broadening Views on Disaster Risk and Disaster Risk Management

Osvaldo Luiz Leal de Moraes*

In literature, disaster risk is usually depicted as a combination of a hazard, usually from nature, combined with vulnerability and exposure. A famous illustration of this is the fleur-de-lis, which can be found in almost all IPCC assessment reports. While such representations are easy to interpret, they fail when combined with a supposedly mathematical representation. This note shows that the usual representation, whether in the form of a figure or an equation, can be treated rigorously when two probabilities are present: the probability of a natural hazard occurring at a location where an anthropogenic hazard is present. In other words, the disaster risk is simply the product of the natural risk times the anthropogenic risk. Furthermore, the mathematical representation of a disaster risk proposed here is a guide for the implementation of disaster risk management measures.
