Natural Hazards Impacting on Future Cities

Natural hazards will have a growing impact on future cities because the climate change dependent hazards will increase in intensity and because of the increasing vulnerability of cities. The global impact of each hazard in any city can be conveniently described through a probabilistic quantified approach to risk and a quantification of resilience. The supply chain must be included in the estimate. Real time methods of risk reduction must be implemented to manage emergencies in future city. It is essential the participation of citizens nudging them to proper behaviors and using also social networks and low cost networked sensors to get the needed information. Several advanced technological methods are available for effective real time risk mitigation as shown in Japan. The application in other countries is hindered by the lack of proper laws and people information programs.
