Natural hazard impacts on industry and critical infrastructure: Natech risk drivers and risk management performance indicators

Industrial facilities and critical infrastructure are vulnerable to the impact of natural hazards. These impacts can trigger so-called Natech accidents and the release of toxic substances, fires and explosions, potentially resulting in health effects, environmental pollution and economic losses. Different factors drive Natech risk, including technical issues linked to the characteristics inherent in Natech events, as well as risk governance and socio-economic challenges. This paper discusses the most important Natech risk drivers in detail, gives examples of existing instruments for Natech risk management in the European Union and at international level, and proposes a set of basic indicators to help measure a country's level of Natech risk reduction. It concludes with targeted recommendations on how to close persisting gaps related to Natech research and policy challenges.
