Post-Event Review Capability

The award winning Post-Event Review Capability (PERC) methodology was created by Zurich Insurance to provide research and independent reviews of large flood events. It seeks to answer questions related to aspects of flood resilience, flood risk management and catastrophe intervention. It looks at what went well, as well as opportunities for improvement, and results in a set of recommendations for the future.

Use this page to learn about the PERC methodology, read full PERC reports or find specific recommendations.

Zurich focused its initial PERCs on floods because floods affect more people globally than any other natural hazard. However, the methodology can be applied to review and learn from other hazard events. We have recently applied it to study the growing peril of wildfires by reviewing the 2017-18 California fires.  

Resilience Lessons from Cyclone Idai and Cyclone Kenneth

The tropical Cyclone Idai and Cyclone Kenneth weather systems, which made landfall in Southeast Africa in March and April 2019 respectively, brought catastrophic destruction and damage to communities across Malawi, Mozambique, and Zimbabwe. The widespread humanitarian disaster resulting from Idai and Kenneth emphasises the need to learn what happened during these events and what can be improved to reduce future risk.

All material from the PERC carried out in Southern Africa by Alliance partners ISET-International, the International Federation of Red Cross and Red Crescent Societies (IFRC), Practical Action, and Zurich Insurance Group - and in collaboration with the Mozambique Red Cross and the Swiss Agency for Development and Cooperation (SDC) is available below, and on ISET-International’s dedicated PERC Idai and Kenneth page.

Educate the public to understand risk and take the right action ahead of and in times of crisis
