UN Volunteers assigned to UN entities such as the United Nations Development Programme (UNDP) and the United Nations Multidimensional Integrated Stabilization Mission in the Central African Republic (MINUSCA), play important roles, advocating for improvements in environmental management and engaging communities to protect the ecosystem. In 2017, 266 UN Volunteers in West and Central Africa, or 17 per cent of all volunteers deployed in the region, served in assignments linked to environmental issues.

The UN sets aside 29 May as the International Day of United Nations Peacekeepers to honour the memory of UN peacekeepers who have lost their lives in the cause of peace. The Day is also to pay tribute to the estimated one million men and women who have served and continue to serve under the blue flag with professionalism, dedication and courage since the first UN peacekeeping mission was deployed in 1948.
