For its 4th edition, the Global Social Economy Forum (GSEF) 2018 was held on the 1st and the 2nd of October in Bilbao. The GSEF aims at reuniting local governments and actors of the Social Economy sector. It represents a great opportunity for public and private stakeholders to get together and discuss points of views and experiences on how to build a better world, centred on human well-being. Xavier Roberti, on behalf of Groupe Terre, member of one of our Belgian members (RES) gave a presentation at the GSEF 2018 during the session on "Entrepreuneurship and Social Innovation", and talked about the relationship between participative social enterprises and unions. While, Aicha Belassir, Director of Faedei, one of ENSIE's Spanish members, gave a presentation about FAEDEI's 2017 Annual Report and ENSIE's "Impact-WISEs" study.
