Welcome to the IOM Environmental Migration Portal, the knowledge platform on people on the move in a changing climate. We aim to provide up-to-date information on key policy processes and developments, capacity building efforts, research and publications, and operational projects addressing the migration, environment and climate change (MECC) nexus. The Portal highlights IOM’s efforts, including with partners, as we work together towards addressing one of the biggest challenges of our times, migration in the context of environmental and climate change.
