Established in 1951, IOM is the leading inter-governmental organization in the field of migration and works closely with governmental, intergovernmental and non-governmental partners.

With 166 member states, a further 8 states holding observer status and offices in over 100 countries, IOM is dedicated to promoting humane and orderly migration for the benefit of all. It does so by providing services and advice to governments and migrants.

IOM works to help ensure the orderly and humane management of migration, to promote international cooperation on migration issues, to assist in the search for practical solutions to migration problems and to provide humanitarian assistance to migrants in need, including refugees and internally displaced people.

The IOM Constitution recognizes the link between migration and economic, social and cultural development, as well as to the right of freedom of movement and mandates the organization to offer a policy forum for dialogue on migration among states.

Since 2007, member states requested IOM within its governing bodies to work on migration, environment and climate change. At the beginning of 2015, a dedicated Migration, Environment and Climate Change (MECC) Division was created to address the migration, environment and climate nexus.

The organization addresses displacement in the context of natural disasters via its Operation and Emergency Department (DOE).

The Organization develops policies and programmes worldwide and pursues three broad objectives in managing environmental migration, intervening at each stage of the migration cycle:

i. To minimize forced and unmanaged migration as much as possible;
ii. Where forced migration does occur, to ensure assistance and protection for those affected and to seek durable solutions; and
iii. To facilitate the role of migration as an adaptation strategy to climate change.

IOM has been active in the field of migration, environment and climate change since the early 1990s, building a comprehensive programme of work that spans policy, research, the development and deployment of data collection tools, capacity-building, advocacy, partnerships, international migration law, communication, knowledge management, fundraising and operational activities. IOM Development Fund currently funds projects on migration, environment and climate change in 15 countries.

IOM policy activities in this thematic area are twofold: mainstreaming human mobility matters into environmental and climate-related processes, and mainstreaming climate and environmental matters into migration policy processes with the organization contributing to migration, climate change, environmental, development, disaster risk reduction and human rights policy processes. IOM is part of the Platform on Disaster Displacement and of the UNFCCC Task Force on Displacement.
