The third Global Agenda item for Social Work and Social Development is “Promoting Sustainable Communities and Environmentally Sensitive Development”. The question of sustainability needs our urgent attention also in social work education due to the alarming environmental problems of the planet, the untenable direction of the global, national and local economy, as well as the persistence of social inequality and human suffering. The relevance of social work for the transdisciplinary issues of sustainability is evident and visible also in the Global Sustainability Goals of the UN (2015.) This E-team is based on an international network for ecosocial transition research and teaching in social work.
