From 23 to 25 June, the Academic Council of the United Nations (ACUNS), in collaboration with the Graduate Institute and UN Geneva, will hold its annual meeting under the theme "Evidence-Based Solutions for Intensifying Global Challenges." The conference's purpose is to bring together scholars and practitioners active in the work of the UN to apprehend and address global challenges.
