Since 2003
With the breaching of dikes by local communities subsequent to the 2003 U.S. invasion of Iraq and the ending of a four year drought that same year, the process has been reversed and the marshes have experienced a substantial rate of recovery. The permanent wetlands now cover more than 50% of 1970s levels, with a remarkable regrowth of the Hammar and Hawizeh Marshes and some recovery of the Central Marshes.
Efforts to restore the marshes have led to signs of their gradual revivification as water is restored to the former desert, but the whole ecosystem may take far longer to restore than it took to destroy. Only a few thousand of the nearly half million Marsh Arabs remain in the area. Most of the rest that can be accounted for are refugees living in other Shia areas in Iraq, or have emigrated to Iran, and many do not wish to return to their former home and lifestyle, which despite its independence was characterised by extreme poverty and hardship. A USAID report noted that while some Maʻdān had chosen to return to their traditional activities in the marshes, especially the Hammar Marshes, within a short time of reflooding, they were without clean drinking water, sanitation, health care or education facilities. In addition, it is still uncertain if the marshes will completely recover, given increased levels of water extraction from the Tigris and Euphrates.
Many of the resettled Marsh Arabs have gained representation through the Iraqi Hizbullah organisation; others have become followers of Moqtada al-Sadr's movement, through which they gained political control of Maysan Governorate. Political instability and local feuds, aggravated by the poverty of the dispossessed Marsh Arab population, remain a serious problem.
