World Wetlands Day – 2 February 2026
What is World Wetlands Day?
World Wetlands Day is celebrated each year on 2 February to raise awareness about wetlands. This day also marks the anniversary of the Convention on Wetlands, which was adopted as an international treaty in 1971.
A United Nations International Day
On 30 August 2021 the UN General Assembly adopted Resolution 75/317 that established 2 February as World Wetlands Day.
Why World Wetlands Day?
Nearly 90% of the world’s wetlands have been degraded since the 1700s, and we are losing wetlands three times faster than forests. Yet, wetlands are critically important ecosystems that contribute to biodiversity, climate mitigation and adaptation, freshwater availability, world economies and more.
It is urgent that we raise national and global awareness about wetlands in order to reverse their rapid loss and encourage actions to conserve and restore them.
World Wetlands Day is the ideal time to increase people’s understanding of these critically important ecosystems.
World Wetlands Day 2026
World Wetlands Day 2026 explores the deep-rooted connections between wetlands and cultural practices, traditions and knowledge systems of communities across the world.
This year’s theme is “Wetlands and traditional knowledge: Celebrating cultural heritage.” The global campaign spotlights the timeless role of traditional knowledge in sustaining wetland ecosystems and preserving cultural identity.
Who is behind World Wetlands Day?
The World Wetlands Day awareness campaign is organized by the Secretariat of the Convention on Wetlands. Contracting Parties of the Convention on Wetlands have been celebrating World Wetlands Day since 1997, when it was first established.
Who can join?
World Wetlands Day is open to everyone — from international organizations, governments, wetland practitioners, to children, youth, media, community groups, decision-makers, to all individuals — as these ecosystems are important for us all.
