This is a contribution from a member of GAP (General Assembly of Partners) reporting on progress in implementing the New Urban Agenda: An ongoing project to improve residents’ well-being by ensuring better understanding, access to and usage of key semi-public spaces. Through collaborative work and action-based research between the Universities and local communities, the project created a pilot digital toolset that provides access to information on the use and perception of this kind of space, fosters social interaction, improves management and generates new knowledge. It explored semi-public space territorialisations regarding association narratives, claims and conflicts, and tactics of reappropriation.
