Setting a trigger is one of the essential components of establishing anticipatory humanitarian action. In the humanitarian and development context, triggers help provide decision-makers the necessary information to know when and where early action should take place and who and what is likely to be impacted. In line with the impact-based forecasting approach, the trigger model is developed based on a detailed risk analysis of natural hazards, including impact assessments of past disaster events, and analysis of exposure and vulnerability data.
This database of triggers serves as a platform for practitioners to see what triggers are being formulated and to facilitate further exchange about the trigger development process.
With the dropdown menus and search options below, you can find trigger information according to hazard, country, sector, lead time, or vulnerability and exposure indicators. The resulting list will provide you with trigger information, a description of the trigger activation process, forecast sources, stop mechanism, and additional details of activation history, where available. The trigger information can serve as a foundation for further research and discussion when developing EAPs and anticipatory action in new contexts.
Growing this database and keeping it up to date is a community effort. If you or your organization would like to add to the trigger database, please download and fill out the following form and send it to Irene Amuron and the Anticipation Hub.
