The Permanent Secretariat of the Alpine Convention, the Andean Mountain Initiative, the UN Environment Programme (UNEP), the International Scientific Committee on Research in the Alps (ISCAR), the Mountain Research Initiative (MRI), and the ARCOS Network are all committed to bridging the gap between science and policy in regional mountain governance, with each of these organisations bringing its own expertise, scientific knowledge and perspectives on managing mountain ecosystems, climate change adaptation, and sustainable development. As co-conveners of this workshop session, the above organisations intend to present their views and contributions on the science-policy interface for regional mountain governance, with a focus on their ongoing efforts to better integrate scientific research into regional governance frameworks to support better decision-making and the specific research needs of decision makers in mountain regions.
