The Rockefeller Foundation's 100 Resilient Cities initiative aims to enhance urban resilience by supporting 100 cities worldwide with technical resources and funding to better prepare for and respond to shocks such as climate change and public health crises. Key components include establishing a Chief Resilience Officer in each city to lead resilience planning and create tailored strategies, alongside a network for knowledge sharing. The initiative emphasizes a collaborative approach involving multiple stakeholders to foster sustainable urban development and improve the wellbeing of vulnerable populations.
