Swiss Re published the much-awaited yearly sigma study on natural catastrophes last week. The highlights: In 2013, there were 308 disaster events, of which 150 were natural catastrophes and 158 man-made. Almost 26000 people lost their lives or went missing in the disasters. Haiyan was the largest humanitarian catastrophe of 2013, killing around 7500 people and leaving more than 4 million homeless. The biggest insured losses came from large scale floods in Europe, accounting for over 4 billion USD. But this year's NatCat sigma was different.

The 2013 NatCat sigma looks beyond the stats to see what the aggravating factors are and what can be done. An important contributing factor to the overall costs is the marked increase of wealth accumulation and settlement in areas highly-exposed to severe weather events. Another one is climate change. As weather-related events become more frequent and more severe, insurance and reinsurance companies are very seriously looking at how to foster climate change resilience. And while emergency preparedness and disaster risk management progressed, there is much more we can do.

The good news, however, is that up to 68% of climate change risks can be avoided with cost-effective adaptation methods. And, alongside local prevention and mitigation measures, risk transfer to re/insurers is a powerful adaptation measure to offset the impact of extreme weather events. See page 17 onwards in the publication.

A refreshing approach being taken in the industry is Zurich's flood resilience program, which uses lessons learned from the European floods to reduce future flood risks. Based on their observations, Zurich highlights the following measures to make communities more flood resilient:
- Improving risk awareness, e.g. Flood maps should be widely available, and used in planning new construction.
- Physical barriers such as levees and flood walls can help but other means of protection should be considered, such as flood water retention areas along rivers.
- Rebuilding structures with improved flood resilience.

The insurance industry can play an important role by providing expert advice on adapting structures to make them able to withstand floods, and mitigating risks. In countries such as Germany, where due to low insurance penetration for natural hazards, only a fraction of flood losses were covered, the government has offered EUR 8 billion to compensate property holders who suffered flood damage. New alliances among insurers, governments and civil society could encourage risk reduction and risk financing in both the public and private sectors. Alternative financing means, including cat bonds, could also play a role. Read the full report from Zurich here.

It is great to see that Zurich’s flood resilience program is mentioned in this blog. We share the view that the insurance industry has a role to play in reducing overall economic flood risk and flood losses. Sharing knowledge and information is an important element. As the Sigma report points out, improvements were made after the 2002 floods, but more can still be done.

As we speak, researchers from the flood resilience program are currently in
the field in Germany again to review the situation almost one year after the 2013 flood event devastated vast areas. We want to highlight again the need for integrated flood risk management, for increased risk awareness and risk averse behavior by the affected population, and want to learn how the upstream-downstream problem along large rivers can be controlled further. We have had great interview partners, and everyone is keen to share their experience and learnings.

Michael, as you show in your publication, key is to continuously improve flood risk management across the risk chain: from risk awareness, to risk mitigation and risk transfer. A great read!

I just found this infographic from Zurich on their flood resilience program:

This comment struck a chord:
"We know that 'after a flood' is really just 'before the next flood'"

Given floods cause so much damage every year, shouldn't building flood resilience be at the top of every government's and company's agenda?
