The aim of the Lesvos Conference is to provide a forum for sharing experiences, practices, critical reflections, methodological as well as empirical advancements on research for and about social ecological and socio-spatial justice. What tasks do social innovation and territorial development research have today and in the future? What role can the territorial commons play for greater socio spatial justice? What methodological and structural constraints and challenges exist for action research in social and social-ecological change strategies? These and other pressing questions will be the focus of what we hope becomes a stimulating gathering of academics, activists, policy makers, artists.
