Methods

Results

IV-a

• Host island-wide stakeholder consultation to compile a list of the hazards to which each island is exposed.
• Prioritize which hazards pose the greatest level of risk.
•  Apply a scoring system to determine which areas rank as high, medium, or low risk.
• Develop a GIS hazard map ranked according to its scores
• Map the risk area for each hazard on the most current base map of the island.
• Assign scores within risk areas using a ranking system.
• Create a hazard summary map to highlight areas that are vulnerable to impacts from multi-hazards.

List of prioritized hazards for use in developing mitigation strategies and prioritizing mitigation projects

IV-b

• Identification of critical facilities and collect data relevant to their vulnerability

critical facilities vulnerability to hazard impacts

IV-c

• Development of damageability/vulnerability curves to allow the determination of estimated loss for the category at different hazard magnitudes To assess their vulnerability to hazard impacts.

expected loss for each scenario, based on the vulnerability to that hazard (as expressed in the vulnerability curves) and the building/ infrastructure replacement cost.

IV-d

• Definition of potential operational impact on each critical facility from each hazard.

Definition of operational guidelines easily adaptable by each facility concerned to build operational resilience to hazards

IV-e

• Identification of areas of special consideration.
• Identification of special consideration areas that are located in high risk areas.

Inventory of special consideration/high risk locations / Inventory of structures in the special consideration/high risk intersections

IV-f

• Identify secondary hazard risk consideration sites and key environmental resource sites.
• Identify intersections of secondary risk sites, environmentally sensitive areas, and natural hazard risk consideration areas.
• Identify key environmental resource locations and their proximity to secondary risk sites.
• Conduct vulnerability analysis on priority critical facilities.

guidelines for conducting detailed assessments of vulnerability on these environmental resource sites.

IV-g

• Compilation and review of current national policies and legislations on disaster risk reduction
• Proposition of mitigation measures based on the result of the vulnerability risk assessment
• Impact estimation of selected mitigation measures: physical, societal, environmental and financial impact

best opportunities for changes in mitigation policy that will have significant impacts on future hazard vulnerability

•    Recommendation of enhancement to existing policies and legislations

IV-h

• Preparation of technical reports that communicates to different stakeholders
• Delivery of stakeholder workshops to share results and solicit feedback
• Preparation to public awareness messages and materials

Long term strategy in a view to monitor and update the vulnerability indices
