11 Facts About Sudd

Sudd is a vast swamp in South Sudan, formed by the White Nile's Bahr al-Jabal section.

In 2019, a study suggested that increased water flows into the Sudd may be partly causing up to a third of the whole West African rise in atmospheric methane levels over the previous decade.

The total area of the Sudd is related to the amount of water reaching Bor from the Albert Nile and from torrents or seasonal watercourses that can add substantial amounts to the flow in the upstream end of the Sudd.

Sudd was designated as a Ramsar Wetland of International Importance in 2006.

Hydrologically the Sudd plays an important role in storing floodwaters and trapping sediments from the Bahr al Jabal.

Over 400 species of bird are found in the Sudd, including shoebills, great white pelicans, and black crowned cranes.

The Sudd provides food and water to large populations of migrating birds.

The Sudd swamp is sustained by the water from the southwestern tributaries and consumes a proportion of the main river through evaporation and transpiration.

The Egyptian government in the 1930s proposed digging a canal east of the Sudd to divert water from the Bahr al Jabal above the Sudd to a point farther down the White Nile, bypassing the swamps and carrying the White Nile's water directly to the main channel of the river.

The draining of the Sudd is likely to have environmental effects comparable to the drying of Lake Chad or the draining of the Aral Sea.
