Defining policies to improve critical infrastructure resilience

Industrial accidents increasingly threaten society and economy; the increasing exposure and vulnerability of our modern interlaced societies contributes to intensifying their impact. Critical Infrastructures (CIs) have a prominent role, since they are vital for the welfare of the population and essential for the economic growth. As hazards are hard to predict, decision-makers need to implement adequate adaptation and mitigation strategies to improve CI resilience. Although CI resilience has attracted increasing attention, empirical studies are rare. Research on the implementation of policies aiming at identifying a clear sequence of measures to improve CI resilience is lacking. Therefore, we present a framework to identify resilience policies across four dimensions (technical, organizational, economic and social) and to define the temporal order in which the policies should be implemented. This research provides a framework grounded in our empirical work. Future work will aim at developing quantitative approaches to complement our results.
