Established in 1997, UNMAS has deployed its specialized expertise across the globe for nearly three decades. Through our 5 Pillars of Mine Action, we are continuing to eliminate the threat posed by mines, explosive remnants of war, and improvised explosive devices by coordinating United Nations mine action, leading operational responses at the country level, and in support of peace operations, as well as through the development of standards, policies, and norms.
UNMAS supports the entire UN system through a small team at headquarters, a humanitarian hub in Geneva, and some 3,000 women and men employed through UNMAS funding in the field.
UNMAS provides direct support and assistance to 19 countries/territories/missions, including:
UNMAS manages a standing capacity for rapid response. In 2025, UNMAS delivered counter-improvised explosive device (IED) and weapons and ammunition management (WAM) training to over 400 personnel across 11 countries.
