World Wetlands Day (WWD) is celebrated worldwide every year on 2 February. It marks the anniversary of the signing of the Convention on Wetlands of International Importance (Ramsar Convention) in Ramsar, Iran, on 2 February 1971.

The Day was first celebrated in 1997. Since then government agencies, NGOs and community groups have celebrated WWD by undertaking actions to raise public awareness of wetland values and benefits and promote the conservation and wise use of wetlands. These activities include seminars, nature walks, festivals, announcement of new Ramsar sites, newspaper articles, radio interviews and wetland rehabilitation.

Theme 2018: "Wetlands for a Sustainable Urban Future" 

Urban wetlands make cities liveable in many important ways. They reduce flooding, replenish drinking water, filter waste, provide urban green spaces, and are a source of livelihoods. Urban wetlands should be integrated into a city’s sustainable future planning and development.
