Borrowing a concept from ecology, urban resilience reframed planning around a city's capacity to absorb shocks and adapt to chronic stresses rather than to deliver a fixed end-state plan. The Rockefeller Foundation's 100 Resilient Cities programme, launched in 2013, funded member cities to appoint a Chief Resilience Officer and produce a citywide resilience strategy. The model spread the role and the strategy template across dozens of cities worldwide. It widened attention from sudden disasters to slow-burn stresses such as poverty, ageing infrastructure and water insecurity.
It shifted planning from fixed, end-state masterplans toward adaptive, ongoing risk management for climate change and disaster. Critics counter that the concept is vague and can depoliticise hard questions about who bears risk and who pays to reduce it.
