DIFFERENT PREVENTIVE STRATEGIES REQUIRE DIVERSIFIED RISK ASSESSMENT MODELS

摘要

The main point that will be discussed in this paper addresses the following question : does it make sense to refer to a universal and unique prototype of risk assessment while considering different goals, preventive measures and strategies? It can be anticipated that the position held here leads to a negative answer, and many examples will be provided to sustain it. The latter will pertain mainly to urbanised environments, for a number of reasons. First, because there is a clear trend worldwide towards growing urban spaces and a preference for urban forms of life. If one examines the development history of large as well as smaller cities along the Mediterranean, a rapid and even dramatic increase can be clearly seen, particularly since the Fifties and the Sixties. The result being a spread of metropolitan areas and conurbations, with urban sprawl covering the space between old centres that were separated entities in the past.
