Navigating uncertainties: collaborative approaches to science-policy dialogues

Science-policy dialogues are becoming increasingly relevant for guiding
evidence-based action on complex environmental challenges, such as marine
conservation. Yet, effective communication of scientific insights to policymakers
remains difficult due to persistent uncertainties, complex problems, and the
need for timely, actionable knowledge. This perspective paper explores the
organization of effective science-policy dialogues, focusing on key challenges
such as communicating uncertainty and establishing shared core messages. To
address these challenges, we propose a structured approach that includes: (1)
identifying specific policy information needs, (2) coordinating interdisciplinary,
multi-institutional research teams, (3) tailoring scientific findings into clear,
audience-focused core messages and options for actions, (4) conducting
targeted dialogue events with policymakers, and (5) evaluating the dialogue
process for continuous improvement. Drawing on experiences at the science-
policy interface and case studies from German research institutions on sea-level
rise and carbon dioxide removal, we present strategies for developing evidence-

based core messages that resonate with policymakers. Our approach highlights
the value of collaborative efforts among multiple research institutions, enabling
a unified scientific voice that establishes both credibility and acceptance among
policymakers. This upstream coordination process between different disciplines
and institutions also improves the scientific quality of policy advice. Ultimately,
this article advocates a structured, collaborative approach to science-policy
dialogues, reinforcing the critical role of science in shaping robust, evidence-
based environmental policy.
