MULTI RISK: A NEW APPROACH FOR DISASTER RISK MANAGEMENT

Tóm tắt

Natural disaster risk assessment is a critical part of a risk management system. Single risk assessment which addresses different natural hazards and their associated risks separately is a popular one used in risk management in Viet Nam. Single risk assessment deals with only one source of disaster ignoring all the possible risk interactions. A multi-risk approach therefore has currently been developed and tested by a number of scholars. This paper introduces a multi-hazard and multi-risk assessment methodology adopted from literature review, which combines single risk assessment and a three-level risk assessment. Multi-risk approaches takes into account the interactions and relations among hazards and among vulnerabilities. It can bring benefits but also challenges to both end-users and scientists.
