Nile Basin in the context of "Nile river"

The Nile (also known as the Nile River or River Nile) is an important river in Africa that flows northwards into the Mediterranean Sea. At roughly 6,650 km (4,130 mi) long, it is among the longest rivers in the world. Its drainage basin covers eleven countries: the Democratic Republic of the Congo, Tanzania, Burundi, Rwanda, Uganda, Kenya, Ethiopia, Eritrea, South Sudan, Sudan, and Egypt. It plays an important economic role in the economy of these nations, and it is the primary water source for South Sudan, Sudan and Egypt.

The Nile has two major tributaries: the White Nile and the Blue Nile. The White Nile, being the longer, is traditionally considered to be the headwaters, while the Blue Nile actually contributes 80% of the water and silt below the confluence of the two. The White Nile begins at Lake Victoria and flows through Uganda and South Sudan, while the Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet at the Sudanese capital of Khartoum.

The Sudd (Arabic: السد, romanized: as-Sudd, Nuer: Baki̱ec, Dinka: Toc) is a vast swamp in South Sudan, formed by the White Nile's Baḥr al-Jabal section. The Arabic word sudd is derived from sadd (سد), meaning "barrier" or "obstruction". The term "the sudd" has come to refer to any large solid floating vegetation island or mat. The area which the swamp covers is one of the world's largest wetlands and the largest freshwater wetland in the Nile Basin.

For many centuries the swamp, and especially its thicket of vegetation, proved an impenetrable barrier to navigation along the Nile. The ancient Egyptians failed to penetrate the Sudd and reach the areas south of it. In AD 61, a party of Roman soldiers sent by the Emperor Nero proceeded up the White Nile but were not able to get beyond the Sudd, which marked the limit of Roman penetration into equatorial Africa. For the same reasons in later times, the search for the source of the Nile was particularly difficult; it eventually involved overland expeditions from the central African coast, so as to avoid having to travel through the Sudd.

The Nile Basin Initiative (NBI) is a partnership among the Nile riparian states that “seeks to develop the river in a cooperative manner, share substantial socioeconomic benefits, and promote regional peace and security”. The NBI began with a dialogue among the riparian states that resulted in a shared vision objective “to achieve sustainable socioeconomic development through the equitable utilization of, and benefit from, the common Nile Basin water resources." It was formally launched in February 1999 by the water ministers of nine countries that share the river: Egypt, Sudan, Ethiopia, Uganda, Kenya, Tanzania, Burundi, Rwanda, the Democratic Republic of Congo (DRC), as well as Eritrea as an observer. From its beginning the Nile Basin Initiative has been supported by the World Bank and by other external partners. The World Bank has a mandate to support the work of the NBI, as lead development partner and as administrator of the multi-donor Nile Basin Trust Fund. One of the partners is the "Nile Basin Discourse", which describes itself as "a civil society network of organisations seeking to achieve positive influence over the development of projects and programmes under the Nile Basin Initiative".

In May 2010, five upstream states signed a Cooperative Framework Agreement (CFA) to seek more water from the River Nile and establish water sharing rights between the NBI states — a move strongly opposed by Egypt and Sudan. Ethiopia, Kenya, Uganda, Rwanda and Tanzania were original signatories with Burundi signing in February 2011. The agreement was subsequently ratified by Ethiopia, Rwanda, Tanzania, Uganda, and Burundi between 2013 and 2023, with South Sudan ratifying the CFA on 8 July 2024. The DRC abstained, while Egypt and Sudan refused to sign on after decrying the CFA as an attempt to diminish their shares of Nile water. Despite these objections, the CFA officially became legally binding over the NBI states on 13 October 2024.
