The Mesopotamian Marshes, also known as the Iraqi Marshes, are a wetland area located in southern Iraq and southwestern Iran as well as partially in northern Kuwait. The marshes are primarily located on the floodplains of the Euphrates and Tigris rivers bound by the cities of Basra, Nasiriyah, Amarah and a portion of southwestern Iran and northern Kuwait (particularly Bubiyan Island). Historically the marshlands, mainly composed of the separate but adjacent Central, Hawizeh and Hammar Marshes, used to be the largest wetland ecosystem of western Eurasia. The unique wetland landscape is home to the Marsh people, who have developed a unique culture tightly coupled to the landscape – harvesting reeds and rice, fishing, and herding water buffalo.
Draining of portions of the marshes began in the 1950s and continued through the 1970s to reclaim land for agriculture and oil exploration. In the late 1980s and 1990s, during the presidency of Saddam Hussein, this work was expanded and accelerated to evict Marsh people from the marshes. Before 2003, the marshes were drained to 10% of their original size. Since the American overthrow of Hussein in 2003, the marshes have partially recovered. However, drought along with upstream dam construction and operation in Turkey, Syria, and Iran have hindered the process. The Mesopotamian marshes were listed as an UNESCO Heritage Site in 2016.
