Water politics in the Nile Basin Water politics in the Nile Basin The Nile river is subject to political interactions. It is the world's longest river flowing 6,700 kilometers through ten countries in northeastern Africa – Rwanda, Burundi, Democratic Republic of the Congo (DRC), Tanzania, Kenya, Uganda, Ethiopia, South Sudan, Sudan and Egypt with varying climates. Considering the basin area of the Nile, Sudan has the largest size (1.9 million km²) whereas, of the four major tributaries to the Nile, three originate from Ethiopia – the Blue Nile, Sobat and Atbara. The modern history of hydropolitics in the Nile basin is very complex and has had
Nile tilapia to this species, too. An undescribed population found at, for example, Wami River, Lake Manyara, and Tingaylanda seems to be a close relative. Nile tilapia The Nile tilapia ("Oreochromis niloticus") is a species of tilapia, a cichlid fish native to Africa from Egypt south to east and central Africa, and as far west as Gambia. It is also native to Israel, and numerous introduced populations exist outside its natural range (e.g., Brazil). It is also commercially known as mango fish, "nilotica", or "boulti". The first name leads to easy confusion with another tilapia traded commercially, the mango tilapia ("Sarotherodon galilaeus").
