The United Nations General Assembly designated 11 December “International Mountain Day”. As of 2003, it has been observed every year to create awareness about the importance of mountains to life, to highlight the opportunities and constraints in mountain development and to build alliances that will bring positive change to mountain peoples and environments around the world.

The Food and Agriculture Organization of the United Nations (FAO) is the coordinating agency for the preparation and animation of this celebration and is mandated to lead observance of it at the global level. The Mountain Partnership Secretariat in the FAO Forestry Division is responsible for coordinating this international process.
