On August 14, 2025, the World Health Organization (WHO) and the University of Antioquia’s Unit of Evidence and Deliberation for Decision Making (UNED) brought together international experts to develop a new global Evidence and Gap Map (EGM) focused on science advisory systems. This initiative aims to bolster national science advice frameworks, ultimately enhancing public health and supporting economic growth across nations.
The consultation is part of a broader effort by WHO to assist countries in strengthening their systems for utilizing evidence in policy-making. Although initiatives to fortify these systems are still in their infancy, the landscape is evolving rapidly, with numerous new tools emerging to facilitate evidence-informed decision-making. Drawing from its extensive experience with the Evidence-Informed Policy Network (EVIPNet), WHO has tasked UNED with the creation of the EGM.
Overview of the Evidence and Gap Map
The EGM serves as a comprehensive resource for governments, providing an extensive overview of the tools available for assessing national science advisory systems and identifying existing gaps. This map consolidates various resources, including the WHO Checklist for Institutionalizing Evidence-Informed Policy-making and the EVIPNet Situation Analysis Manual. By highlighting the available tools, their applications, and the areas needing improvement, the EGM assists governments in evaluating their systems and enhancing the integration of science in public policy.
During the consultation, participating experts described the initiative as both rigorous and comprehensive. They offered recommendations to increase its relevance across different contexts and underscored the necessity for supplementary tools that translate the map’s findings into actionable guidance for decision-makers. The feedback emphasizes the importance of tailoring the EGM to meet the diverse needs of countries at various stages of developing their science advisory systems.
Future Developments and Goals
WHO and UNED plan to continue refining the EGM, ensuring it remains an accessible resource for all Member States. The goal is to foster a greater reliance on evidence in public policy, thereby improving health outcomes and contributing to sustainable economic development. By equipping governments with the tools and knowledge necessary to assess and strengthen their science advisory systems, this initiative represents a significant step forward in the global effort to make evidence-informed policy-making the standard rather than the exception.
As countries navigate increasingly complex health challenges, the development of robust science advisory systems will be crucial. The EGM stands to play a vital role in guiding nations towards more effective governance and better health outcomes based on sound scientific evidence.
