Every day, community members develop projects in response to many different needs, and emerging or unmet aspirations: housing, design and creation of green spaces, resource sharing, knowledge transfer, etc. These actions position community members at the centre of social transformations. The recognition and support of local governments for these social innovations enhances their sustainability and their impact. Through its work to foster community mobilization and its collective management tools, the SSE movement also has a role to play in ensuring the sustainability and the impact of these initiatives.
