Actionable science, where researchers and end users of science partner to identify, characterize and develop solutions to address environmental impacts like climate change, is becoming increasingly popular and widely-used across research disciplines and sectors. However, co-producing knowledge and delivering ‘actionable’ science requires building and navigating relationships between researchers, communities, decision-makers, and practitioners, and often crossing the science-policy interface. Because they are able to facilitate collaboration and information flow across networks and disciplines, boundary organizations are well-positioned to build capacity for scientific information delivery and use. This session emphasizes the co-production process from the perspective of boundary organizations (which include research and extension organizations, grant funders, and NGO’s) and seeks to illuminate the ways boundary organizations support knowledge co-production and how they address challenges that naturally arise within this work, such as communication, managing expectations, sustainable funding, and program evaluation. Abstracts that consider co-production with diverse communities are especially welcome.
