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

Submitted by Julia Barrott | published 23rd Feb 2016 | last updated 19th Apr 2023


Environmental change is one of the major concerns for the international community. Although precise estimates are unavailable, it is commonly understood that due to changes in the environment, more and more people will migrate in coming years, in particular within and between developing countries. At the same time, migration will most likely have a growing impact on the environment. For example, internal migration to cities is expected to continue to increase. Today, over half of the world’s population lives in urban areas, many of which are in coastal areas and are particularly vulnerable to sea level rise. The effects of these changes will vary and the impact will differ between each region of the world.

Despite a growing body of studies on the topic of migration, environment and climate change, there is still a lack of reliable data and policy oriented research which can respond to the increasing demand and reflect the needs of policymakers.

The Migration, Environment and Climate Change: Evidence for Policy (MECLEP) project aims to contribute to the global knowledge base on the relationship between migration and environmental change, including climate change. The innovative research will aim to formulate policy options on how migration can benefit adaptation strategies to environmental and climate change.

The MECLEP project therefore fills an important gap as it is a policy oriented programme of work based on three main components of activities.

Project Location

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