Cities are carrying a growing share of global pressure. They hold the responsibility for climate adaptation, public health, social stability and basic services, often with limited resources and competing demands.

Over the past decade, Chief Resilience Officers, city teams and partners have turned resilience from a concept into daily work. They have built governance roles, planning tools, neighbourhood programmes, risk systems, finance approaches and learning platforms that are already delivering results.

This Call to Action recognises that progress and sends a clear message to the wider ecosystem: cities cannot do this alone. If resilience is to reach more people, the systems and partners around cities need to scale with them.
