The fifth PAGES Open Science Meeting (OSM) will take place from 9-13 May 2017 in Zaragoza, Spain. The Scientific Program Committee invites scholars to take an active part in organizing the scientific program of the conference. The program will be comprised of plenary, parallel and poster sessions. The plenary sessions will host keynote talks intended to stimulate discussions on the role of past global change science in providing information about strategies for a sustainable world, on the engagement of stakeholders in active cutting-edge research, and on the added value of interdisciplinary approaches. The parallel and associated poster sessions will accommodate top-level ongoing research. Up to three sessions will be run in parallel, allowing accommodation of 24 parallel sessions. Please suggest sessions with a provisional title, potential conveners and a brief description. The Scientific Program Committee will prepare the session program based upon your input, aiming at a fair balance between the topics. Proposals are welcome at firstname.lastname@example.org until 1 May.
