The United Nations General Assembly proclaimed 21 March the International Day of Forests (IDF) in 2012. The Day celebrates and raises awareness of the importance of all types of forests. On each International Day of Forests, countries are encouraged to undertake local, national and international efforts to organize activities involving forests and trees, such as tree planting campaigns.
The theme for each International Day of Forests is chosen by the Collaborative Partnership on Forests.

Wetlands are ecosystems, in which water is the primary factor controlling the environment and the associated plant and animal life. A broad definition of wetlands includes both freshwater and marine and coastal ecosystems, such as all lakes and rivers, underground aquifers, swamps and marshes, wet grasslands, peatlands, oases, estuaries, deltas and tidal flats, mangroves and other coastal areas, coral reefs, and all human-made sites such as fishponds, rice paddies, reservoirs and saltpans.

On February 21, 2025 the Government of Mongolia and the United Nations Convention to Combat Desertification (UNCCD) signed an agreement paving the way for the 17th session of the Convention’s Conference of the Parties (COP17) in Ulaanbaatar in 2026. COP17 will bring together UNCCD’s 197 Parties in a crucial global forum to accelerate action against desertification, land degradation and drought. As one of the most affected countries by desertification, with nearly 77 per cent of its land degraded, Mongolia will leverage COP17 to drive solutions for land restoration, sustainable land management and resilience-building across the world.

The Seventeenth Meeting of the Conference of the Parties (COP17) to the Convention on Biological Diversity (CBD) is scheduled to take place from 19 to 30 October 2026 in Yerevan, Armenia. This significant event will bring together representatives from governments, indigenous peoples and local communities, non-governmental organizations, and other stakeholders to discuss and make decisions on global biodiversity conservation and sustainable use.
