Intergovernmental science policy organizations assess and mediate knowledge for decision makers, especially their member governments. The Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) is known as a trailblazer in acknowledging plural knowledge systems because of the multiple evidence base approach it has adopted, which has challenged the older operating principles of credibility, policy relevance, and legitimacy. This paper juxtaposes those principles and the multiple evidence base to study their context-sensitive synergies and tensions, based on experts’ perceptions of IPBES operations.

This study asked UK policymakers if there are common topics for which evidence is requested over time that cut across government departments or agencies, and if there is a preferred style in the way evidence is requested?

Research on the conditions for effective engagement between research and policy demonstrates whether policymakers should be involved earlier in the creation of research projects.
