It is noteworthy that the most successful examples seem to be based on the type of community engagement that adheres to the principles of social and solidarity economy, but political leadership and supportive public policies are also key (chapters 4 and 7). International networks and initiatives such as ICLEI-Local Governments for Sustainability or the Rockefeller Foundation’s 100 Resilient Cities foster learning and exchange between municipalities at very different stages of development to promote resilience to a variety of environmental, social and economic challenges (chapter 7). They recognize the importance of communities and make use of shared learning to promote local resilience strategies and innovative approaches for sustainability. A multifaceted approach is often key.
