Post-Event Review Capability

The award-winning Post-Event Review Capability (PERC) is a methodology created to review hazard events that become disasters to understand what happened and identify entry points for building or strengthening resilience. 

PERCs have been conducted across the globe after floods, wildfires and tropical cyclones, and have been applied in both urban and rural settings. Individual study results include practical recommendations for action, while multi-PERC reviews identify common strengths and gaps applicable to virtually any context. 

Initially, Zurich focused on floods because floods affect more people globally than any other natural hazard. Recent years have seen a number of severe floods around the world; cyclones causing severe flooding in Tabasco, Mexico; intense rain causing widespread flooding in Senegal; extreme monsoon seasons in Bangladesh; and heavy rainfall causing devastating flooding across western Europe. Each of these disasters was distinct in the way they manifested, but they provide insights into what worked well and what can be learned to reduce future risk.

Materials from the Bangladesh, Mexico, Senegal and western Europe PERCs are available below.
