In the six years since the creation of 100 Resilient Cities, more than 70 cities have published Resilience Strategies containing over 3,000 initiatives. To date, more than US$25 billion has been catalyzed by 100RC member cities toward the resilience agenda, and the world’s leading development financial institutions are building resilience criteria into how large-scale infrastructure projects are funded. This report is meant to inspire, to capture the lessons we’ve learned from working in this space over the past six years, and to serve as a practical guide for new actors hoping to learn how they too can participate in this global movement to make cities more forward-looking, inclusive, integrated, and risk-aware. Cities are the main audience, especially those who hope to begin or will continue resilience journeys of their own, and who will benefit from the lessons and replicable stories spanning the entire 100RC Network. City partners, thought-leaders, investors, and all urban resilience practitioners, however new to the field, will also find insights and learnings they can bring to their own work.
