The River Nile

The source of the Nile is in the Nyungwe Forest in Rwanda. From there, it travels northwards for 6,718km,[1] making it the longest river in the world. The area of the basin is 2.9 million km2 or about one tenth of the area of Africa. It is shared by 11 sovereign countries. These are Burundi, Democratic Republic of Congo, Egypt, Eritrea, Ethiopia, Kenya, Rwanda, South Sudan, Sudan, Tanzania and Uganda.

The Nile basin has astonishing geographic diversity and climatic zones. No other river in the world begins in volcanoes and mountains with glacial snows and ends in deserts. Indeed, no other major river flows northwards, traversing almost 36 degrees of latitude. However, in terms of flow volume, it rates low among the great rivers of the world. It is 2% of the Amazon, 15% of the Mississippi and 20% of the Mekong. It is comparable to the Rhine but smaller than the Zambezi, the Congo and the Niger.[2]

A salient feature of the Nile is its seasonal and annual variation in the volume of discharge. More than 80% of the annual flow occurs from August to October, and only about 20% occurs during the remaining nine months.[3] The seasonal flood is regular, but its volume is not and has always been unpredictable. The annual discharge can be as low as 41BCM, as in 1913/1914, or as high as 141BCM, as in 1988. As shown in Table 2 and Map 1, the Nile has five sub-basins: the equatorial lakes, Bahr al-Ghazal, Sobat River, the Blue Nile and Atbara River.Agreement, as explained below.

Shared and disputed surface and groundwater resources

The Nile River is the main shared surface water resource. The management of the Nile basin waters has historically been staggered and sectorial. Short-term national interests and narrow disciplinary professional polarization are the overriding constants, disregarding the international character of the river and the nature of its finite resources. Almost all the Nile basin countries were under British rule, which had vested interests in Egypt and its cotton.[6], [7] Individual Nile basin countries developed and managed their own isolated projects in the absence of a transboundary masterplan.[8] The main players have traditionally been engineers and politicians. In spite of the many treaties that have been drawn up, Egyptian interests have dominated.[9] In short, it has been a history of conflict rather than cooperation, and the countries have failed to ratify the Cooperative Framework Agreement, as explained below.

Treaties and agreements

In 1929, an agreement was made between the Nile basin countries, nearly all of which were under British rule. Thirty years later came the 1959 Nile Water Agreement between Egypt and Sudan, which excluded the other basin countries. Its salient stipulations are that:

• The two countries will uphold their position on ‘acquired rights’ of the allotted shares of water;
• The benefits of the envisaged control project will be divided equally between the two countries;
• Projects will be developed for saving the lost waters in the Nile basin;
• Technical cooperation will be strengthened.

Launched in February 1999, the Nile Basin Initiative provided hope for basin-wide cooperation, although it excluded Eritrea. It should have evolved into the Cooperative Framework Agreement and eventually the Nile Basin Commission. However, Egypt and Sudan were firmly against it. South Sudan’s stance is not clear.[10]
