The Belgian Science Policy Office (BELSPO) has invited Holger Straßheim to chair a panel at an international conference on "Social Sciences, Arts, and Humanities and the future of evidence-informed policymaking“ (6-7 May 2024, Royal Museum for Central Africa, Tervuren). The conference is organized within the frame of the Belgian Presidency of the Council of the European Union. BELSPO emphasizes the need for multidisciplinary approaches in policymaking beyond linear models of science-policy advice. It brings together more than 150 participants. The panel chaired by Straßheim will focus on paradigmatic examples of boundary-crossing organizations such as the Finnish Academy of Science, the Netherlands Scientific Council for Government Policy (WRR) and UNESCO-MOST BRIDGES, a transdisciplinary and cross-regional mechanism that provides humanities-driven science to member states.
