2018 DRR Financing 5.6 Maxim Bouev

David Simmons notes that catastrophe insurance has traditionally focused on property loss but its scope is wider, such as disaster response. Existing catastrophe risk models do not account for second- and higher-order effects of critical infrastructure failures. Network analysis can help model how failures may diffuse through interconnected systems. Even with perfect models, risks may remain if key infrastructure components lie outside a country's borders.

2018 DRR Financing 5.6 Maxim Bouev
- 3. MAIN POINTS • David Simmons: «Historically catastrophe insurance has focussed on property loss, but the scope is far wider, e.g. disaster response» • Modelling catastrophe risks is part of a wider problem – the correct accounting of economic risks that a country, a region or a city faces • For many countries in the region in question we do not still have a reliable risk model • Existing modelling do not take into account second- (and higher) order effects when assessing risks, and probable maximum loss • Second-order effects depend on critical infrastructure (CI) and its importance for impact diffusion pathway • Network analysis helps to model that • Even if we have a perfect model – what if central points in CI lie beyond country borders?
