Cultural diversity is both a big challenge and an invaluable resource for any city. When it is recognized and adequately taken into account, cultural diversity becomes a driving force of economic, social and cultural development because it generates multiple forms of civic engagement and synergy among the different approaches. By strengthening communities’ capacities to meet their needs and supporting local civic engagement, the SSE plays a key role in promoting social cohesion in a context of cultural diversity, while highlighting the benefits of this diversity. In this sense, it is a natural ally of local governments that are also seeking to promote the use of all the cultural resources of their territories.
