Qualitative single-case study assesses early warning systems' effectiveness in fishing communities, suggesting improvements for disaster preparedness.

Key Points

  • The study aims to evaluate the operational performance of community-based early warning systems in the context of climate-related hazards.
  • Qualitative single-case study design
  • Key informant interviews (n = 18)
  • Household interviews (n = 28)
  • Focus group discussions (n = 42)
  • Application of the UNDRR four-pillar framework to assess system capacity
  • Communities have significant local risk knowledge and strong informal communication networks.
