The myriad forms of community involvement positively influence cities’ economic and social sustainable development, and social cohesion facilitates the participation of all actors in this development. The SSE, due to its roots in the community, promotes civic engagement and identifies and works on issues related to social cohesion that are specific to each city, helping to make them more inclusive economically, socially, culturally, technologically, etc. In this respect, partnerships with city governments can take different forms to foster the integration of all residents and communities, thereby reinforcing and enriching the social fabric.
