There’s growing awareness in the Islamic Republic of Iran that wetlands are valuable and sustain livelihoods.
Ramsar, “the gem of northern Iran”, is the town that gives its name to the Ramsar Convention.
The Convention is an intergovernmental treaty that provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. It came into force more than 40 years ago.
The Islamic Republic of Iran has 24 sites designated as wetlands of international importance (Ramsar sites) out of 2,290 worldwide. Of Iran’s 24 sites about one third are under pressure or in a critical condition.
Wetlands are vital for biodiversity. Large populations of migratory birds winter there or use them on their way to and from wintering areas in Africa or the Indian sub-continent.
The Convention uses a broad definition of wetlands. It includes 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 fish ponds, rice paddies, reservoirs and salt pans.
The Islamic Republic of Iran has been struggling to prevent its lakes and wetlands from drying up owing to extensive extraction of water by farmers for irrigation, growing extraction for non-agricultural uses, and climate change.
A telltale signal of vanishing wetlands is the increased frequency and intensity of dust storms in Iran and across the region. The adverse situation has been compounded by 14 years of drought, according to Barbara Slavin, director of the Future of Iran Initiative at the Atlantic Council.
Sand and dust storms, the advance guard of desertification, have been identified as one of the “emerging issues of environmental concern” in UN Environment’s latest Frontiers Report.
“The anthropogenic causes of sand and dust storms include deforestation and unsustainable agricultural practices as well as excessive water extraction and the modification of water bodies for irrigation and other purposes,” says the report.
In the long term, only sustainable land and water management, integrated with measures addressing climate change mitigation and adaptation, can improve the situation.
Iran is trying to deal with the problem. Its National Biodiversity Strategic Action Plan, Target 18, states: “By 2030, conservation and wise use of wetlands are strengthened and the situation for at least 50 per cent of degraded wetlands is improved.”
Lake Urmia, a Ramsar site and UNESCO Biosphere Reserve, is a vast hypersaline lake with many islands, surrounded by extensive brackish marshes, in northeastern Iran. The lake is fed by rainfall, springs and streams and subject to seasonal variation in level and salinity. The brackish marshes are an important staging area for migratory waterbirds.
Around 6.4 million people and 200 species of birds live in the Urmia basin.
The lake ecosystem supports biodiversity and provides recreation and mental health benefits, as well as water for agriculture and industry. If the lake were to dry up completely, dust storms and disaster could result.
A study between 2002-2011 in the eastern sub-basin of Lake Urmia showed that agricultural activities, the expansion of farmland, and population increases over the last three decades led to the over-exploitation of resources, causing land degradation. The lake has been in decline since 1995. By August 2011, its surface area was only 2,366 km2, according to UN Environment. It further declined to 700km2 in 2013. NASA satellite data indicate that the lake lost about 70 percent of its surface area between 2002 and 2016.
The Islamic Republic of Iran is working with development partners and local communities to improve the situation. Engineering works have helped unblock and un-silt the feeder rivers, and there has been a deliberate release of water from dams in the surrounding hills. In September 2016 the Government of Iran and the Food and Agriculture Organization launched a four-year sustainable management project for the lake.
Recent indications are that the lake is recovering. The lake surface area is now 2,300 km2 (UN Development Programme, 2017). UN Environment’s November 2017 Foresight brief focuses on the extent of this recovery and measures being put in place to ensure this is sustained.
In neighbouring Iraq, the Hawizeh Marsh, which extends across the border into Iran where it is known as Haur Al-Azim, was designated as the country’s first Ramsar site in 2007. Around 20-25 per cent of this wetland is in the Islamic Republic of Iran.
Part of the Mesopotamian marshland complex fed by the Tigris and Euphrates rivers, the whole region is suffering from the construction of upstream water control structures, increasing water extraction for agriculture as well as reduced rainfall.. As a result, the Hawizeh marsh was placed on Ramsar’s register of threatened wetlands requiring priority attention.
In mid-2017, the Government of Iraq requested the Ramsar Secretariat to organize an advisory mission to the marshes to identify ways for future cooperation between Iraq and Iran as a first step towards the long-term conservation and sustainable development of the marshes, including ways to reduce the incidence of sand and dust storms.
The mission, which took place from 16 to 23 December 2017, involved officials from Iraq and Iran participating in workshops and conducting site visits on both sides of the border to better understand the situation. In cooperation with the Ramsar Secretariat, UN Environment is helping support the dialogue process which also includes consultations with local communities and participation of UN agencies.
Areas of agreed future cooperation include carrying out waterbird surveys, creating a platform for exchanges of technical and scientific information on the ecology of the marshes, and joint celebration events on wetlands and water.
In a quick and positive step forward, a team of Iraqi bird experts joined Iranian surveyors in conducting a midwinter waterfowl count on the Iranian side of the marshes from 23-26 January 2018. Similarly, Iranian experts plan to collaborate in the waterfowl census in Iraq in early February 2018.
“Wetlands for a Sustainable Urban Future” is the theme for World Wetlands Day on 2 February 2018.
