Information - SPM1 Risk at different scales: A policy and regulatory dilemma
Event Information
NATIONAL SCALE RISK ASSESSMENT vs. LOCAL SCALE RISK ASSESSMENT
1.National risk assessment
A national-scale risk assessment for natural hazards is an outgrowth of a Government's desire to set a concrete socio-economic policy to protect its citizens from catastrophic natural hazards. For example, the question whether the socio-economic impact of Hurricane KATRINA could have been less if The US would have taken different mitigation actions if a national risk framework were in place. Is there a methodology for national scale risk assessment? Such an assessment would not be useful land use planning, or would it?
2.Local risk assessment
Most of us have experienced on a local risk assessment for natural hazard events. Is it possible to apply traditional risk assessment methods for evaluating local risk assessment? In other words, is a national risk assessment simply an aggregate of individual local risk assessment? Can the methodology for a local scale risk assessment be extended to national scale risk assessment? Is such aggregation possible because of the requirement of the amount of time and resources to complete a systematic assessment at large scale. Not only that, such extension is not desirable because national risk assessment is mainly for government wide policy, not land-use planning
3.Level of uncertainty for a national scale risk assessment
How is uncertainty considered at both scales?
These and other issues will be discussed at the splinter panel discussion. Please join us for a stimulating session.
