In a context of polycrisis, in which various disturbances and risks affect individuals, collectives and societies, it is becoming increasingly important to involve scientists, decision-makers, technicians and citi-zens in producing and disseminating the knowledge produced about social reality. Mobilising participation and citizenship in this co-produc-tion process is a mandatory task. The dossier organised by Oliveira and Queirós discusses a series of theoretical, methodological and empirical contributions to designing interventions that are necessarily glocal in nature, as they involve an intense articulation of scales, and in which the co-responsibility of all those involved is vital.In this dossier, the reader will find texts in Portuguese by researchers with different disciplinary backgrounds in Social Sciences and Humani-ties. The richness of the reflections raised by reading them comes from the range of themes, objects, methodologies and results that authors from different disciplinary traditions put into dialogue, pointing the way to renewed proposals around community intervention and metropolitan development.
