Roland Friedli presented on the challenges and risks of critical infrastructure at a conference on community resiliency. He discussed issues like cascading effects between interdependent systems, aging infrastructure, and infrastructure operating near capacity. He provided examples of past infrastructure failures, such as shortages, construction delays, disease outbreaks, and natural disasters. These examples illustrated how single points of failure or unforeseen events can disrupt critical services. Finally, he suggested ways the insurance industry could help mitigate infrastructure risks through assessment, incentivizing prevention, and being cautious of risks that are difficult to insure.
