Ramsar Convention

The only global treaty devoted to a single type of ecosystem: wetlands. Signed on 2 February 1971 in the Iranian city of Ramsar, it now has 172 member countries.

Three pillars of the Convention

By joining the Convention, a country takes on three commitments.

  • Wise use

    Treat all wetlands on its territory with care — not only the protected ones.

  • Ramsar sites

    Include the most valuable wetlands in the List of Wetlands of International Importance and manage them well.

  • Cooperation

    Work with neighbours on shared rivers, lakes and migratory species.

What counts as a wetland

The Convention’s definition is very broad: any land where water stands permanently or temporarily, from high-mountain lakes to rice paddies.

  • Natural

    Lakes, rivers, marshes, peatlands, oases.

  • Coastal

    Sea coasts, deltas, bays, tidal flats.

  • Man-made

    Reservoirs, fish ponds, salt works.

  • Agricultural

    Rice paddies, irrigated land, seasonally flooded meadows.

How a site joins the list

  1. A country selects a site that meets at least one of nine criteria.
  2. It prepares a Ramsar Information Sheet (RIS) and a boundary map.
  3. The Convention Secretariat reviews the documents and publishes the site in the RSIS database.

What Ramsar site status brings

  • International recognition of the site’s value
  • A commitment to preserve its natural character
  • A basis for management plans, monitoring and reporting
  • Support and exchange of experience with other countries

Selection criteria

The first criterion is a type of wetland that is rare or unique for the region. The other eight concern biodiversity: endangered species, fish and waterbirds. For example, a site qualifies if it regularly supports 20,000 waterbirds or 1% of the entire population of a species.

Wise use

The Convention’s main principle: wetlands can and should be used — for fishing, cutting reed, grazing livestock, receiving tourists — but in a way that does not erode their natural properties. Nature conservation is not set against the lives of the people who live nearby.

  • National policy

    Taking wetlands into account in government planning.

  • Inventory

    Assessment of condition and monitoring.

  • Management plans

    A conservation strategy for each site.

  • Education

    Training specialists and working with the public.

Why it is urgent

Wetlands are disappearing faster than forests. Central Asia knows the price of this better than most: the Aral Sea, once the fourth-largest lake in the world, almost dried up within a few decades. The experience of many countries shows that protection, restoration and good management can halt degradation.

2 February — World Wetlands Day

On this day in 1971 the Convention was signed. In 2021 the UN General Assembly made it an official international day.
