Managing infrastructure resilience and adaptation

The paper contributes to strategic thinking about infrastructure resilience and adaptation. A technique is presented in a case study for analysing options on the timing of protection against climate change. Predetermined trigger points for responses to resilience weaknesses are discussed, showing how flowcharts can act as prompts to the need for action. The roles of national governments in improving resilience in key areas are discussed. The paper introduces the concept of a 'chain of resilience' for interdependent infrastructure systems and identifies some key questions for national governments to ask about the linkages between systems before requiring appropriate remedial actions. Practical steps for private owners and investors to increase resilience in their own infrastructure are identified. Some suggestions for tackling the increasingly important area of cyber resilience are presented. The use of actuarial techniques is discussed.
