The Mesopotamian Marshes, also known as the Iraqi Marshes, are a wetland area located in Southern Iraq and southwestern Iran. [ 6 ] [ 1 ] [ 2 ] [ 3 ] 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.
The Mesopotamian Marshlands were once the largest wetland ecosystem in the Middle East, covering an area of 15,000 to 20,000 square kilometers. [27] In the 1980s and 1990s, this marshland was drained by upstream dams and water control structures, down to 10% of the original area. [27] The marshland is located on the intercontinental flyway of ...
The marsh cities were built on water. The people who live there lead simple lives. They make houses out of reeds without electricity or cars, and generally have no education. The people fish, hunt, and cultivate buffalo. [2] The area where the fresh waters reaches the marshes is far from the cities.

[15] By the late 1990s, the Central Marsh had become completely desiccated, suffering the most severe damage of the three main areas of wetland.
Map showing the extent of Mesopotamia. The geography of Mesopotamia, encompassing its ethnology and history, centered on the two great rivers, the Tigris and Euphrates.While the southern is flat and marshy, the near approach of the two rivers to one another, at a spot where the undulating plateau of the north sinks suddenly into the Babylonian alluvium, tends to separate them still more ...
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. It is a rare aquatic landscape in the desert, providing habitat for the Maʻdān and important populations of wildlife.
The erosion of hard ocean substrates by living organisms through various biological mechanisms. biogenic Of biological origin – Produced by the present or past activity of living organisms, or by a biological process. bioherm Landform of organic sedimentary rock enclosed or surrounded by rock of different origin. biostratigraphy
Soil erosion is the main factor for soil degradation and is due to several mechanisms: water erosion, wind erosion, chemical degradation and physical degradation. Erosion can be influenced by human activity. For example, roads which increase impermeable surfaces lead to streaming and ground loss.
