Boundary organizations serve as critical connectors, translating scientific knowledge into actionable policy and practice while integrating diverse knowledge systems to foster systemic change (Guston, 2001). By acting as facilitators of cross-sector collaboration, these organizations enhance the epistemic community of sustainability transformations, ensuring that insights from research effectively inform and shape governance and implementation strategies. This webinar will explore how Transformations Community, cCHANGE and SocSES, each playing a boundary organization role, can work together to strengthen science-policy-practice linkages for sustainability.
