Governance is fundamental for the optimization of water management, whether it is about minimizing the impact of extremes or maximizing the benefits from water use. For improving governance, ensuring that science is credible, salient and legitimate, is essential in integrating science into policy and management. Depending on the context, integration of science takes a variety of forms, using a wide variety of communication methods. Key approaches relate to decision support, stakeholder engagement, co-creation, and the idea of bridging research and policy-making communities. This session seeks any contribution that aims to report on or advance the state of understanding on these topics. Contributions are also specifically invited regarding how uncertainty is discussed, managed and communicated as part of this integration process. The session is co-sponsored by the Water and Society and Hydrologic Uncertainty Technical Committees.
