Land use planning and management of cities and different zones of industrial/commercial activities represents a major challenge today. Decision makers have to consider complex sets of constraints of different nature and to integrate wider range of risks before taking decisions and committing resources for medium and long term planning. These constraints may be of societal, economical, geo-political and even ethical nature. They need rationalizing their decisions and minimizing potential risks in order to guarantee an acceptable level of global security. Risks could be of varying kinds: natural, man-induced, systemic or criminal. These different sources of risk are interacting in today’s developed societies. Subsequently, rational and optimized land use planning decision-making process can’t be guaranteed except through the development of multidisciplinary robust tools and methodologies based on full identification of risks.
