Post-Event Review Capability

The 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.

Maintain institutional memory.

The fact that government staff (i.e., Chief District Officers, army, police) are frequently transferred poses major problems for response; ‘institutional memory’ is not retained within districts. Mechanisms need to b...

Build and maintain relationships within and across sectors.

For multi-organizational response mechanisms such as the cluster system to work efficiently, relationships need to be built and maintained with and between organizations and government stakeholders, between sectors, and ...

Further develop existing EWS and replicate the systems in other regions.

Even though they didn’t function entirely as planned, the EWS in Kailali and Bardiya Districts dramatically reduced loss of life and property. The EWS should be further strengthened by addressing single points of fai...

Design, install and maintain protection systems in ways that don’t ultimately exacerbate risk.

Flood protection systems in the Tarai currently reduce short-term risk while increasing long-term risk. Embankments need to be designed considering sedimentation rates, the possibility of safe failure, and accounting for...

Build redundancy and safe failure into critical systems.

All ‘core’ systems (i.e., food, water, shelter, power, communications, transportation) need to have built-in redundancy so that they can continue to work during and after extreme events. For example, key communicatio...
