World Wetlands Day

World Wetlands Day gives visitors a date-specific entry point into wetland ecosystems, water storage, flood resilience, biodiversity, and habitat protection. The countdown keeps that purpose visible while separating the observance from nearby environment pages with different ecosystems, audiences, and forms of participation. Wetlands include marshes, peatlands, mangroves, floodplains, and other water-linked habitats; this is not a general ocean day.

Introduction

World Wetlands Day is observed every year on February 2. It marks the adoption of the Convention on Wetlands in Ramsar, Iran, on February 2, 1971.

The day raises awareness of wetlands as ecosystems that support biodiversity, water security, food, flood protection, carbon storage, culture, recreation, and livelihoods. The United Nations General Assembly formally proclaimed February 2 as World Wetlands Day in 2021.

What counts as a wetland

Wetlands include marshes, swamps, peatlands, floodplains, mangroves, estuaries, deltas, seagrass beds, coral-associated shallow waters, lakeshores, and some human-made systems such as rice fields and reservoirs.

The Convention on Wetlands uses a broad definition because water depth, salinity, vegetation, flooding, and seasonal conditions vary widely.

Wetlands in human history

Wetlands have provided fish, reeds, salt, grazing, fertile soils, transport routes, medicines, water, and spiritual places.

Many civilizations developed around rivers and floodplains, while Indigenous peoples and local communities built detailed knowledge of seasonal water, species, fire, harvesting, and navigation.

Drainage and conversion

For centuries, governments and landowners treated many wetlands as wastelands to be drained for agriculture, urban development, ports, roads, and mosquito control.

Drainage often increased short-term land availability while reducing flood storage, wildlife habitat, water purification, and cultural access.

The rise of international wetland conservation

During the twentieth century, scientists and conservation organizations documented declining waterbird populations and habitat loss along migratory routes.

Because birds cross borders, wetland conservation required cooperation among countries rather than isolated protected areas.

The Ramsar Conference

Representatives met in the Iranian city of Ramsar on the shores of the Caspian Sea in 1971.

They adopted the Convention on Wetlands of International Importance Especially as Waterfowl Habitat on February 2.

The Convention enters into force

The treaty entered into force in 1975.

Countries joining the convention commit to the wise use of wetlands, international cooperation, and designation of at least one Wetland of International Importance, commonly called a Ramsar Site.

Wise use

The convention’s concept of wise use means maintaining the ecological character of wetlands through ecosystem approaches within sustainable development.

It does not mean that all human activity must be excluded; it means that use should not destroy the functions and values on which ecosystems and communities depend.

The Ramsar List

The List of Wetlands of International Importance includes sites selected for ecological, hydrological, botanical, zoological, or other criteria.

International designation can strengthen recognition, but protection still depends on national law, management, finance, monitoring, and local participation.

The Montreux Record

The Montreux Record identifies listed sites where ecological character has changed, is changing, or is likely to change because of human activity.

It is intended to encourage attention, technical support, and corrective action rather than simply naming sites as failures.

Creating World Wetlands Day

World Wetlands Day was first celebrated in 1997 by governments, organizations, schools, communities, and conservation groups.

Annual themes and educational materials helped connect the treaty anniversary with public outreach.

United Nations recognition

On August 30, 2021, the United Nations General Assembly proclaimed February 2 as World Wetlands Day.

The resolution emphasized the need to reverse accelerating wetland loss and promote conservation and restoration.

Wetlands and flood protection

Floodplains, marshes, mangroves, and coastal wetlands can absorb, slow, and store water.

They reduce some flood and storm risks, although they cannot eliminate danger from extreme events or substitute for safe planning and infrastructure.

Peatlands and climate

Peatlands store very large amounts of carbon in waterlogged soils.

Drainage and fire can release greenhouse gases, while rewetting and restoration can protect carbon stores and biodiversity.

Mangroves and coastal systems

Mangroves provide nursery habitat, fisheries support, shoreline stability, carbon storage, and storm protection.

Aquaculture, coastal construction, pollution, and altered freshwater flows have damaged many mangrove systems.

Freshwater biodiversity

Wetlands support fish, amphibians, reptiles, insects, birds, mammals, aquatic plants, and microorganisms.

Freshwater species face pressure from dams, pollution, invasive species, overharvesting, drainage, and climate change.

Indigenous rights and traditional knowledge

Many wetlands are living cultural landscapes governed and cared for by Indigenous peoples and local communities.

Conservation should recognize land tenure, customary law, free and informed participation, sacred relationships, and the authority of knowledge holders.

Restoration

Wetland restoration may involve removing drains, rewetting peat, reconnecting rivers and floodplains, controlling invasive species, restoring tidal flows, and reducing pollution.

Successful restoration requires long-term monitoring and should not be used to justify destroying intact wetlands elsewhere.

Historical timeline

Early twentieth century: Concern grows over waterbird and wetland decline.

February 2, 1971: The Convention on Wetlands is adopted at Ramsar.

1975: The convention enters into force.

1990: The Montreux Record is established.

1997: The first World Wetlands Day is celebrated.

2015: Wetland protection is linked with the Sustainable Development Goals.

August 30, 2021: The UN General Assembly proclaims World Wetlands Day.

February 2, 2022: The first UN-recognized observance is held.

Today: The day promotes wetland conservation, wise use, and restoration.

World Wetlands Day today

Events include guided walks, school programs, restoration work, bird counts, exhibitions, community mapping, policy forums, and Indigenous-led cultural activities.

The strongest observances avoid treating wetlands as empty land. They recognize living communities, cultural heritage, ecological limits, and the importance of protecting intact systems before relying on restoration.

Participation can include visiting or restoring wetlands responsibly, learning about local watersheds, monitoring wildlife, and supporting habitat stewardship. Activities should fit local regulations, safety guidance, accessibility needs, and the current campaign theme. Visitors can use the countdown to plan a relevant action without assuming that every country or community marks World Wetlands Day in the same way.
