As a leader of one of the oldest gnostic religions in the world, Sheikh Nidham Kreidi al-Sabahi must use only water taken from a flowing river, even for drinking.<\/p>\n
The 68-year-old has a long grey beard hanging over his simple tan robe and a white cap covering his equally long hair, which sheikhs are forbidden from cutting. He says he has never got ill from drinking water from the Tigris River and believes that as long as the water is flowing, it is clean. But the truth is that soon it may not be flowing at all.<\/p>\n
Iraq\u2019s famed Tigris is heavily polluted and at risk of drying up. Unless urgent action is taken to save the river, life will be fundamentally altered for the ancient communities who live on its banks.<\/p>\n

\u201cNo water, no life,\u201d says Sheikh Nidham, a Mandaean religious leader living in the southern Iraqi city of Amarah, on the banks of the river in which he has been regularly immersed since he was a month old.<\/p>\n
Mandaeans are members of one of the oldest gnostic religions in the world. Southern Iraq has been their homeland for more than a thousand years, particularly in Maysan province. Amarah, the provincial capital, is built around the Tigris. Water<\/a> is central to their faith and every major life event requires ritual purification. Marriage ceremonies begin in water, and before drawing their last breath, Mandaeans should be taken to the river for a final cleansing.<\/p>\n \u201cFor our religion, the importance of water is like air. Without water, life wouldn\u2019t exist. At the beginning of creation, Adam was the first man on Earth. Before Adam there was water, and water was one of the elements that created Adam,\u201d Sheikh Nidham explains.<\/p>\n The Tigris is one of the two famous rivers that cradle Mesopotamia and once formed part of the \u201cfertile crescent\u201d. The river rises in south-east Turkey, and runs the length of Iraq, through its two largest cities, Mosul and Baghdad, until it joins the Euphrates; together, as the Shatt al-Arab, they finish their journey south to the Gulf.<\/p>\n Map of Iraq and the wider region<\/a><\/p>\n Here, on the banks of these rivers, the history of the world was changed. Large-scale agriculture was first developed, the first words were written, and the wheel was invented. Today the Tigris waters are used for irrigation, transport, industry, power generation, and drinking for the estimated 18 million Iraqis<\/a> who live within its basin.<\/p>\n \u201cAll the life of Iraqis depends on the water. All the civilisation and all the stories that you hear, it depends on those two rivers. It\u2019s more than water to drink or to irrigate or to use or to wash \u2026 It\u2019s more even than spirituality,\u201d says Salman Khairalla, the founder of Humat Dijlah<\/a>, a non-governmental organisation dedicated to protecting the river.<\/p>\n But the health of the river has been in decline for decades. Iraq had state-of-the-art water infrastructure until the US made it a target in 1991\u2019s Operation Desert Storm. With treatment plants destroyed, sewage flowed into the waterways. Years of sanctions and conflict mean the infrastructure has never fully recovered. Today, across southern and central Iraq, just 30%<\/a> of urban households are connected to a sewage treatment facility. That number drops to 1.7% in rural areas.<\/p>\n In addition to municipal waste, chemical fertilisers and pesticides in agricultural runoff, industrial waste including from the oil sector, and medical refuse<\/a> all find their way into the river. A 2022 study<\/a> found that water quality at numerous sites in Baghdad was rated \u201cpoor\u201d or \u201cvery poor\u201d. In 2018, at least 118,000 people<\/a> in the southern city of Basra were treated in hospital after drinking contaminated water.<\/p>\n An aerial view taken in September 2021 shows a dried-up riverbed in the Huwaiza marshes about 260 miles (420km) south of Baghdad, on the Iraq-Iran border.

In the past 30 years, Turkey has built major dams on the Tigris and the amount of water reaching Baghdad has decreased by 33%<\/a>. Iran too has built dams and diverted water away from shared rivers that feed the Tigris. Within Iraq, water is frequently overused, especially in the agricultural sector that uses<\/a> at least 85% of the country\u2019s surface water.<\/p>\n The climate crisis is taking a toll. Iraq has recorded a 30%decline<\/a> in precipitation and is in the grip of its worst drought in nearly a century. Demand for fresh water is expected to exceed supply by 2035. This summer, the Tigris was so low people could easily walk across<\/a> it.<\/p>\n Khairalla believes that upstream dams and mismanagement are the areas of biggest concern because as the river\u2019s volume drops, the concentration of pollutants increases. \u201cThe water quality depends on the quantity,\u201d he said.<\/p>\n The Iraqi government has had to repeatedly press its northern neighbour to release more water from its dams. Wastage in Iraq is one of the concerns frequently raised<\/a> by Turkish officials in these discussions.<\/p>\n In November, Baghdad and Ankara signed a mechanism<\/a> to tackle some of the river\u2019s problems: stopping pollution, introducing modern irrigation technologies, reclaiming agricultural land, and improving water governance. It has been described as an \u201coil-for-water\u201d accord as infrastructure projects will be undertaken by Turkish companies and paid for with oil funds. The Iraqi foreign ministry touted it as a \u201cfirst of its kind<\/a>\u201d deal.<\/p>\n The agreement, however, has drawn harsh criticism from experts, environmental activists, and the public, who are concerned about the lack of detail that has been released, that it appears to hand Ankara control of Iraq\u2019s water resources, and is not officially binding.<\/p>\n Fishing boats in a depleted river in the Huwaiza marshes, near Amarah, on the Iraq-Iran border.
