Dominica Case Study:Prioritization of Interventions for Shelter Vulnerability ReductionCaribbean DRM and CCA – Spatial Data to Inform Decision-Making Workshop
Introduction Objective of the ongoing process Reduce the risk emergency shelters are facing in order to ensure the safety of the population • Carry out a process for the prioritization of interventions (funding limitations) • Coordinate amongst a multitude of ministries (Ministries of Local Government, Works, Education, ODM, Red Cross, etc.) ¡Work in Progress!
Methodological Approach Risk Vulnerability Exposure Hazard 3
Component I: Hazard Risk Vulnerability Exposure Hazard 4
Component I: Hazard The shelters are determined to provide refuge during hurricane events. This gives rise to the necessity to consider:

Component II: Exposure and Vulnerability Risk Vulnerability Exposure Hazard 8
Component II: Exposure and Vulnerability Material and condition of the structure A) Location & Building Characteristics: Roof type and condition Hurricane straps? Hurricane Shutters Location Building Characteristics …
Component II: Exposure and Vulnerability A) Location & Building Characteristics: • A shelter assessment is carried every year prior to the hurricane season in which all shelters are visited and structurally assessed • Before 2013, no GPS coordinates were collected • Before 2013, the assessment was not digitized
Component II: Exposure and Vulnerability A) Location & Building Characteristics: • The surrounding topography in which the shelter is located • The physical characteristics of the building (the number of stories, roof type, openings, etc.) • Floor area to house occupants during and after the event
Component II: Exposure and Vulnerability B) Physical Vulnerability Evaluation: Key Components that govern building vulnerability to hurricane wind: • The area of openings • Shutters • Roof cover • Exterior wall and wall cracks • Number of stories • Surrounding topography (steepness of the slope)
Component II: Exposure and Vulnerability B) Physical Vulnerability Evaluation: Worst combination of characteristics • Buildings with un-shuttered large openings AND • metal roof in dubious condition Worse combination of characteristics • Buildings with un-shuttered large openings OR • metal roof in dubious condition • Steep terrain • Multiple stories Bad combination of characteristics • Buildings with un-shuttered large openings OR • metal roof in dubious condition
Component II: Exposure and Vulnerability C) Social Vulnerability or “Criticality”: Level of Importance of and Reliance on shelters in order to keep the population safe
