MECLEP is three-year project, running from January 2014 to December 2016.

The aim of the project is to contribute to the global knowledge base on the relationship between migration and environment change, including climate change. The research is conducted with the aim of formulating policy options on how migration can benefit adaptation strategies to environmental and climate change.

The project focuses on three types of mobility – migration, displacement and planned relocation – as well as internal and international movements. Research and data collection was conducted in six different countries: Dominic Republic, Haiti, Kenya, Mauritius, Papua New Guinea and Vietnam.

Climate and environmental change is one of the most pressing concerns for the international community now and in the coming years. Migration has an impact on the environment and environmental degradation and disasters also lead to movements. In the coming years an increasing number of people are anticipated to migrate due to environment and climate change, especially within and between developing countries.

Although there is a growing interest migration in relation to the environment and climate change–and an increasing number of studies being conducted on the topic–the data required to effectively respond to these challenges and policy needs are still lacking.

MECLEP is managed at IOM’s Global Migration Data Analysis Centre (GMDAC), a hub for fact-based analysis on global migration trends and policies.
