Draining of the Mesopotamian Marshes
The draining of the Mesopotamian Marshes occurred in Iraq and to a smaller degree in Iran between the 1950s and 1990s to clear large areas of the marshes in the Tigris-Euphrates river system. Formerly covering an area of around 20,000 km2 (7,700 sq mi), the main sub-marshes, the Hawizeh, Central, and Hammar Marshes and all three were drained at different times for different reasons. Initial draining of the Central Marshes was intended to reclaim land for agriculture but later all three marshes would become a tool of war and revenge.
Many international organizations such as the U.N. Human Rights Commission, the Supreme Council of the Islamic Revolution in Iraq (SCIRI), the International Wildfowl and Wetlands Research Bureau, and Middle East Watch have described the draining as a political attempt to force the Ma'dan people out of the area through water diversion tactics.
The marshes had for some time been considered a refuge for elements persecuted by the government of Saddam Hussein, as in past centuries they had been a refuge for escaped slaves and serfs, such as during the Zanj Rebellion. The area was formerly populated by the Marsh Arabs or Ma'dan, who grazed buffalo on the natural vegetation and grew rice. By the mid 1980s, a low-level insurgency against Ba'athist drainage and resettlement projects had developed in the area, led by Sheik Abdul Kerim Mahud al-Muhammadawi of the Al bu Muhammad under the nom de guerre Abu Hatim.
The British were the first to drain Iraq's marshes which had no apparent economic value and bred mosquitoes. Prepared in 1951, The Haigh Report outlined a series of sluices, embankments and canals on the lower ends of the Tigris and Euphrates that would drain water for agriculture. In 1952, the Third River (a large canal) commenced that would drain part of the Central Marshes but it was not complete until 1992 as well as the Nasiriyah Drainage Pump Station which was not completed until 2009. During the 1970s, the expansion of irrigation projects had begun to disrupt the flow of water to the marshes. By the early 1980s, it was evident that irrigation projects were already affecting water levels in the marshes. Part of the Hammar Marsh was also drained in 1985 to clear area for oil exploration.
Gulf War Draining
However, after the First Gulf War (1991), the Iraqi government revived a program to divert the flow of the Tigris River and the Euphrates River away from the marshes. This was done to prevent any remaining militiamen from taking refuge in the marshes, the Badr Brigades and other militias having used them as cover.
The flow southwards from the distributary streams of the Tigris was blocked by large embankments and discharged into the Al-Amarah or Glory Canal, resulting in the loss of two-thirds of the Central Marshes by as early as 1993. A further canal, the Prosperity Canal, was constructed to prevent any overflow into the marsh from the main channel of the Tigris as it ran southwards from Qalat Saleh. By the late 1990s, the Central Marsh had become completely desiccated, suffering the most severe damage of the three main areas of wetland. By 2000, United Nations Environment Programme estimated that 90% of the marshlands had disappeared.
The Central Marshes stretched between Nasiriyah, Al-'Uzair (Ezra's Tomb) and Al-Qurnah and were mainly fed by the Tigris and its distributaries. They were characterised by tall qasab reeds but included a number of freshwater lakes, of which the largest were the Haur az-Zikri and Umm al-Binni (literally "mother of binni", the latter being a species of barbel.) The marshes supported breeding populations of the Basra Reed-warbler and Marbled Teal, along with several other species of non-breeding birds. A bird subspecies unique to the marshes, the African Darter Anhinga rufa chantrei, may have already become extinct by the 1990s. There were also populations of several mammal species including the unique Erythronesokia bunnii (Bunn's Short-Tailed Bandicoot Rat) and the Smooth-coated Otter subspecies Lutra perspicillata maxwelli, which had only been described from specimens obtained in the Central Marshes.
A study by the Wetland Ecosystem Research Group at Royal Holloway, University of London concluded that thousands of fish and waterfowl died as the waters receded, and that the central Qurnah marshes 'essentially no longer exist as an ecosystem'.
- The loss of a migration area for birds migrating from Eurasia to Africa, and consequent decrease in bird populations in areas such as Ukraine and the Caucasus
- Probable extinction of several plant and animal species endemic to the Marshes
- Higher soil salinity in the Marshes and adjacent areas, resulting in loss of dairy production, fishing, and rice cultivation.
- Desertification of over 7,500 square miles (19,000 km2).
- Saltwater intrusion and increased flow of pollutants into the Shatt-al-Arab waterway, causing disruption of fisheries in the Persian Gulf
The majority of the Maʻdān were displaced either to areas adjacent to the drained marshes, abandoning their traditional lifestyle in favour of conventional agriculture, to towns and camps in other areas of Iraq or to Iranian refugee camps. Only 1,600 of them were estimated to still be living on traditional dibins by 2003. The western Hammar Marshes and the Qurnah or Central Marshes had become completely desiccated, while the eastern Hawizeh Marshes had dramatically shrunk.
The Marsh Arabs, who numbered about half a million in the 1950s, have dwindled to as few as 20,000 in Iraq, according to the United Nations. An estimated 80,000 to 120,000 have fled to refugee camps in Iran.
The plan, which was accompanied by a series of propaganda articles by the Iraqi regime directed against the Ma'dan, systematically converted the wetlands into a desert, forcing the residents out of their settlements in the region. Villages in the marshes were attacked and burnt down and there were reports of the water being deliberately poisoned.
Along with the Gulf war sanctions, there was no specific legal recourse, or prosecution of those involved with the project. Article 2.c of the Convention on the Prevention and Punishment of the Crime of Genocide forbids “deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part.” The Saint Petersburg Declaration says that “the only legitimate object which States should endeavour to accomplish during war is to weaken the military forces of the enemy.” Since water flowed unfiltered into the Gulf, The Kuwait Regional Convention for Co-operation on the Protection of the Marine Environment from Pollution could be used to compensate Iraq’s neighbours for the increase of the marine pollution, but it does not protect the Maadan for the loss of their marshlands.
Following the 2003 U.S. invasion of Iraq, embankments and drainage works were broken open, and the marshes began to reflood. The Central Marshes showed little recovery through 2003, but by early 2004 a patchwork of lakes had appeared in northern areas; there was flooding in southern areas which had previously been dry since the early 1990s. There has been some corresponding recolonization by the natural marsh vegetation since that time, and return of some species of fish and birds, although recovery of the Central Marshes has been much slower compared to the Huwaizah and Hammar Marshes; the most severely damaged sections of the wetlands have yet to show any signs of regeneration. Erythronesokia bunnii, Lutra perspicillata maxwelli and Anhinga rufa chantrei are all thought to have become extinct.
