Machar Marshes: Nile Basin (South Sudan)

Reference work entry


The Machar marshes are the major wetland in the Sobat basin, in South Sudan. The Sobat is a tributary of the White Nile originating from the Ethiopian highlands. The wetland is formed by the spill from the Baro River and the inflows from the eastern torrents (Yabus and Daga). The Machar marshes is an important ecosystem that supports rich flora and fauna and provides grazing land for the Nilotic tribes of South Sudan. Unlike other wetlands in Southern Sudan (e.g., Sudd), the Machar marshes is the least monitored and understood. The literature shows different estimates of the flooded area, varying between 3,350 and 20,000 km2. This chapter provides a description of the Machar marshes, its biodiversity and the water resources system, as well the key challenges for conservation and/or development of the marshes.
