Mitigation may be described as: “Sustained action taken to reduce or eliminate long-term
risk to people, property, environment, and the economy from hazards and their effects”.
Mitigation before disaster strikes is essential. There will always be the potential for an earthquake or flooding. However, the amount of damage and destruction caused by these hazard events can be limited through mitigation.
Mitigation Strategies include:
- Avoidance: Actions that eliminate the chance of hazard from occurring
- Loss Prevention: Actions that reduce the probability of an occurrence
- Loss Reduction: Actions that reduce the consequences of an event
These strategies are used in the development of Mitigation Plans. Mitigation Plans form the foundation for a long-term strategy to reduce disaster losses and break the cycle of disaster damage, reconstruction, and repeated damage. The EmerGeo Framework for Resilience is a framework for risk-based decision making with a focus on reducing damages to lives, property, and the economy from future disasters.
While there are no short cuts to effective Mitigation planning, the aggregation capability provided by EmerGeo mapping utilized in the Hazard, Risk, Vulnerability and Capability Assessment (HRVCA) phase can definitely simplify the effort.
For example, assume you that you found that flooding was a threat and knew, based on inundation maps, where the water will go. By marrying the data together in EmerGeo software and running a flood model we can analyze how long and high a dyke must be; thereby enabling calculation of the amount it will cost. We could also do the cost benefit analysis to calculate the cost differences if we did not build the protective works. A similar scenario could be run for hazardous material, seismic or other threats (or combinations of threats).
