A call for protection and conservation of the Sudd Wetlands.
The Sudd region in South Sudan is one of the world’s largest freshwater ecosystems and a unique geographical and hydrological phenomenon in the Nile River basin. The name “Sudd” derives from the Arabic word “السد”, meaning “barrier” or “obstacle”, referring to the dense vegetation and floating islands that have historically made navigation extremely difficult for explorers and sailors. This vast area, located within the White Nile basin, plays a pivotal role in the climatic and environmental balance of East and Central Africa.
The Sudd region is situated in central South Sudan, where the White Nile (specifically the Bahr el-Jebel) flows from the equatorial highlands in the south into a large basin depression. The permanent area of the swamps is approximately 30,000 square kilometres, but during severe flood seasons, it can expand to cover up to 130,000 square kilometres, equivalent to the size of some small countries.
The Sudd’s hydrology is complex; the White Nile loses approximately 50% of its water as it flows through this region due to evaporation and transpiration. While this process may appear to be a water loss for downstream countries, it is the primary driver of the local ecosystem, which relies on periodic flooding. The region is comprised of a complex network of channels, lakes, lagoons, and marshes whose features are constantly changing based on the volume of inflows from Lake Victoria and local rainfall.
The Sudd is designated a Ramsar site, a protected area under the international convention for wetlands of international importance. The vegetation in the area is dominated by papyrus (Cyperus papyrus), which can reach several metres in height, along with water hyacinth and hay grasses that form floating vegetation islands known as sudd or al-Sudd.
The Sudd is a haven for thousands of species. The area is a strategic stopover for migratory birds travelling between Africa and Europe. It is home to the largest population of the endangered shoebill, as well as pelicans and storks. It experiences one of the largest wildlife migrations in the world, with thousands of white-eared kob and ting migrating across the marshes in search of seasonal grazing. The area also supports populations of elephants, African buffalo, and hippos.
