Empirical evidence shows that acting on early warnings can help humanitarian organizations reduce losses, damages and suffering while reducing costs. This paper explores the application of the valuation approach ('value of information') to select which forecasts (magnitude, probability and lead time) should trigger humanitarian actions. Based on the above, the authors suggest the following best practices:
Forecast value must be determined in collaboration with actors;
Collaboration between development and humanitarian donors;
Use of the valuation approach for developing early warnings.
