About International Mountain Day
International Mountain Day is a United Nations observance held every year on December 11 to focus attention on the world's mountain regions and the people who live in them. Mountains cover roughly a quarter of the planet's land surface and are home to more than a billion people, yet their real reach is far wider: they supply fresh water to half of humanity, feed great rivers, shelter an outsized share of the world's biodiversity, and anchor agriculture, tourism, and culture from the Andes to the Himalaya.
Each year the day carries a specific theme chosen by the Food and Agriculture Organization, which coordinates the observance, covering issues such as climate change, biodiversity, mountain foods, and youth opportunities in mountain communities. Schools, universities, conservation groups, and governments mark the date with hikes, exhibitions, conferences, and tree plantings. It is a day for learning how fragile mountain ecosystems are and why protecting them protects everyone downstream, which is to say nearly everyone.
History of International Mountain Day
International Mountain Day grew out of the United Nations International Year of Mountains in 2002, a global effort that raised awareness of mountain ecosystems and the pressures on them. Encouraged by that momentum, the UN General Assembly designated December 11 as International Mountain Day starting in 2003, and the Food and Agriculture Organization was asked to lead each year's campaign. The date honors the anniversary of the adoption of a chapter on mountains in Agenda 21, the action plan agreed at the 1992 Rio Earth Summit. Since then, each edition has highlighted a theme such as mountain biodiversity, mountain forests, freshwater, and the role of mountain peoples as stewards of fragile landscapes. The observance has helped keep mountain issues on the agenda of climate talks and development programs around the world.
