On Friday 9, in the auditorium of the Universidade de Santiago de Compostela, the Fundación RIA presented "When we were sustainable. Learning in the Barbanza the keys to the future". A publication that gathers the conclusions of the first year of research of the Laboratorio Ecosocial do Barbanza and focuses on a very specific region of Galicia, the Barbanza peninsula, to value the forms of land management historically carried out by local communities and to promote initiatives in the region that are governed by the same principles of sustainability. Lessons are drawn from this process to show possible approaches to economic, social and environmental issues that are also relevant outside this territory.
