Why critical infrastructure is the hidden force behind global risk

“Infrastructure is the mechanism through which risk really spreads.” – Anne-Marie Kirkman, Strategic Growth Initiative - Program Office Lead

Most global risk outlooks highlight familiar threats such as climate change, cyber attacks, geopolitical instability and economic uncertainty. Yet one of the most important strategic questions often receives far less attention: what happens when those risks converge on the infrastructure that underpins modern society?

Critical infrastructure is rarely the source of these risks. Instead, it is the system through which they interact, amplify and cascade across communities, industries and economies. As infrastructure networks become increasingly interconnected, resilience depends less on protecting individual assets and more on understanding how entire systems behave under pressure.

In this episode, Anne-Marie Kirkman joins Ben Hall, Global Thought Leadership Manager at GHD, to explain why organisations need to move beyond traditional asset-level thinking and adopt a systems approach that strengthens resilience across energy, water, transport, communications and the broader economy.

• Critical infrastructure is often underestimated because it sits across multiple risk categories rather than within a single one
• Infrastructure failures can amplify climate, cyber, geopolitical and economic risks through cascading system impacts
• Modern infrastructure is increasingly interconnected, making system-wide resilience more important than protecting individual assets
• Organisations need to understand the dependencies between infrastructure systems before disruption occurs
• Investing in infrastructure resilience strengthens economic productivity, community wellbeing, energy security and national resilience simultaneously
