Possibilities of restoring the Iraqi marshes known as the Garden of Eden

The Iraqi marsh lands, which are known as the Garden of Eden, cover an area about 1500020000 sq. km in the lower part of the Mesopotamian basin where the Tigris and Euphrates Rivers flow. The marshes lie on a gently sloping plan which causes the two rivers to meander and split in branches forming the marshes and lakes. The marshes had developed after series of transgression and regression of the Gulf sea water. The marshes lie on the thick fluvial sediments carried by the rivers in the area. The area had played a prominent part in the history of man kind and was inhabited since the dawn of civilization by the Summarian more than 6000 BP. The area was considered among the largest wetlands in the world and the greatest in west Asia where it supports a diverse range of flora and fauna and human population of more than 500000 persons and is a major stopping point for migratory birds. The area was inhabited since the dawn of civilization by the Sumerians about 6000 years BP. It had been estimated that 60% of the fish consumed in Iraq comes from the marshes. In addition oil reserves had been discovered in and near the marshlands. The climate of the area is considered continental to subtropical. The average annual rainfall ranges between 42 to 185mm.The air temperatures rises to more than 50C during summer and drops to the freezing point in winter. The main marshes are Al Hammar 2800 km2, Qurnah 3000 km2 and Al Huweizah 2350 km2. During flood seasons however, the marshes much larger areas. Through the 20 century, construction of major hydraulic works and the construction of dams at the upstream parts of the Tigris and Euphrates Rivers in Turkey and Syria played an essential role in controlling the floods and minimizing the flow of the main rivers. Saddam regime began to drain the marsh lands so that troops can be moved into that area and use the water to block the advances of the Iranian troops and perhaps to get rid of the marsh dwellers due to the fact they participated in appraisal against him in 1991. To enable the army to move inside the marshes, the central government started to execute five major drainage projects to prevent water from the Tigris and Euphrates Rivers from reaching the marches. Later, the army launched a major attack against marsh dwellers using artillery, mortar and ground attacks. The area was highly contaminated by army munitions and poison gas. Accordingly, two third of the marshes were not receiving water inputs in 1993 and at 2000 less than 10% remained. The consequences were that most of the marsh dwellers left their places and some animals and plants are extent now. The government at that time, to change the entire environment of the marshlands, implemented many agricultural projects in the dried areas of the marshlands. The total areas invested in these projects are 1920 km distributed over three governorates which are Thi-Qar, Maissan and Basrah. Water and Climate Change in the MENA-Region Adaptation, Mitigation,and Best Practices International Conference April 28-29, 2011 in Berlin, Germany After the fall of Saddam regime in 2003, the Iraqi government with the help of other countries and international organizations started the process of restoration and rehabilitation of Iraqi marshes. There are number of difficulties encountered in the process such as land use changes, climatic variations and changes, soil and water salinity as well as ecological fragmentation where many species were affected as well as the marsh dwellers. In this research we would like explore the possibilities of restoring the Iraqi marshes. It is believed that 7075% of the original areas of the marshes can be restored. The exact areas are 1800, 1800 and 2425 km2 for Al Hammar, Al Hawiza and Central marshes. This implies that 12886 MCM water should be available to achieve this goal keeping the water quality as it is. In case the water quality is to be improved then 18863 MCM of water is required. This requires plenty of efforts and international cooperation to overcome the existing obstacles. They include opening dialogue with riparian countries for water allocations, preventing saline and polluted water from entering the marshes, public awareness programs, use of non conventional methods in irrigation and water augmentation and maintaining the distribution systems.
