The Environmental Migration Portal: Knowledge Platform on People on the Move in a Changing Climate seeks to provide a one-stop service website to promote new research, information exchange and dialogue, intended to fill the existing data, research and knowledge gaps on the migration-environment nexus.

The Environmental Migration Portal has been created as part of the "Migration, Environment and Climate Change: Evidence for Policy (MECLEP)" project funded by the European Union. 


Migration, Environment and Climate Change: Evidence for Policy (MECLEP)

The European Union-funded “Migration, Environment and Climate Change: Evidence for Policy” (MECLEP) project was implemented between January 2014 and March 2017.

The project aimed to contribute to the global knowledge base on the relationship between migration and environmental and change. More specifically, it aimed to formulate policy options on how migration, including displacement and planned relocation, can benefit adaptation strategies to environmental and climate change. It involved research, capacity-building and dialogue and knowledge sharing activities.

The 6 project countries were Dominican Republic, Haiti, Kenya, the Republic of Mauritius, Papua New Guinea and Viet Nam.

The project was implemented by the International Organization for Migration through a consortium of six research partners.

Policy Briefs

The Migration, Environment and Climate Change Policy Brief Series seeks to contribute to the current global knowledge base by providing reliable and precise information on the topic of migration and environmental change, including climate change. Its objective is also to present related and appropriate policy options by identifying recommendations, good practices and lessons learned to harness the positive impacts of migration in adapting to environmental changes.

The Policy Brief Series is a reader-friendly online publication intended for policymakers and other stakeholders working in the field of migration, environment and climate change adaptation policies.

The Migration, Environment and Climate Change Policy Brief Series welcomes submissions from policymakers and researchers worldwide. Please see the guidance note for more information.

South Asia, comprising 8 countries including Bangladesh, the Maldives and Nepal, is affected by a range of natural disasters including floods, glacial lake outburst floods (GLOFs), storm surges, droughts, cyclones and heavy precipitation. These disasters take a huge toll as they displace thousands of people every year. The impact of natural hazards is amplified by the following facts: most countries in the region lack strong economies and infrastructure, majority of the population and the industries depend on land resources, and large proportions of the population live in environmentally vulnerable areas.

The State of Environmental Migration series gathers the expertise of researchers, students and professionals to provide an annual assessment of the changing nature and dynamics of environment- and climate-related migration throughout the world.

The International Centre for Integrated Mountain Development (ICIMOD) is a regional intergovernmental learning and knowledge sharing centre serving the eight regional member countries of
