Stress-Testing the Resilience of Critical Infrastructures Exposed to Polycrises Triggered by Emerging Risks

The article introduces a new approach to stress-testing the resilience of critical infrastructures that are exposed or potentially exposed to adverse events, polycrises, or disasters. It focuses on extreme threats (XTs) that may trigger polycrises and proposes the use of resilience and threat indicators, quantitative stress-testing methods, and standardized solutions. This integrated approach seeks to address a current gap by contributing to the development of a widely accepted stress-testing framework for critical infrastructures facing increasingly complex and interconnected risks.
