Global Survey of Early Warning Systems

This report synthesises the findings of a global survey that identifies gaps in early warning systems, which was carried out by the UN International Strategy for Disaster Reduction (UNISDR) in collaboration with a multi-party working group.

It comments on mixed progress made in each of the UNISDR's four elements of early warning systems: risk knowledge; monitoring and warning service; dissemination and communication; and response capability. The report highlights areas where considerable advances have been made for example in developing the knowledge and tools required to assess risks and communicate predictions and warnings — as well as where significant inadequacies still exist, such as basic equipment and skills.

The report also discusses challenges that need to be overcome for each of the above elements of early warning systems. It identifies cross-cutting issues, including insufficient coordination and a lack of participatory approaches, and concludes with a summary of recommendations for the next steps towards creating a comprehensive global early warning system for all natural hazards.
