Spatial Commons between Conviviality & Planetarism
The symposium will deal with the potential of collectively organised commons resources for our urban and rural habitats and living environments. The extent to which such commons can contribute to the preservation and promotion of the planet’s habitability depends largely on how they succeed in organising cooperation and social interaction.
The symposium will therefore focus on the relationship between the social and ecological dimensions, which is crucial for the practice of commoning. How can this be conceptualised and put into practice?
Contributors from various disciplines and countries will discuss examples from theory and practice, past and present, and question the analytical potential of the concepts of the convivial and the planetary.
