Designated by the United Nations General Assembly in 2003 to "encourage the international community to organize events at all levels on that day to highlight the importance of sustainable mountain development," International Mountain Day is observed every year on December 11 with themes relevant to sustainable mountain development.
The theme for 2023 is “Restoring Mountain Ecosystems.”
Mountains are home of the 15% of the world´s population and a quarter of the world’s land animals and plants. They provide freshwater for everyday life to half of humanity.
