Abstract
Ethiopia, Sudan and Egypt entered into dispute since Ethiopia began the construction of the Renaissance Dam along the Blue Nile in 2011. This article is aimed at assessing the core facts about water conventions, the use of trans-boundary rivers and the main argument points of Egypt and Sudan against Ethiopia's use right of the Nile. Data were obtained from conventions and laws, study reports and television interviews. Percent and ratios were used for quantifying data. The 1997 UN Water Convention, having seven criterions for equitable water use by riparian nations, is a better platform for the negotiation on the Nile water. Ethiopia contributes 86.52 billion m(3) to the Nile water although Egypt's contribution is negligible. Despite the built-up of 3 huge dams by Egypt and over 10 by Sudan, these countries aggressively contest the Renaissance Dam of Ethiopia. Egypt diverts about 46 billion m(3) water for irrigation. Turk, an upstream nation (alike Ethiopia in the Nile basin), built 11 dams along the Tigris and Euphrates Rivers with rare contest from the downstream nations. The existence of 'adequate rainfall' and 'other rivers' in Ethiopia, the colonial treaties, the Nile as the only resource, and the impact of the Renaissance Dam are among the main points of argument of Egypt and Sudan against Ethiopia's use right of the Nile. The Nile water use by Ethiopia is inevitable as 73.7 % of the rivers' flow, 65.3 % of the hydropower and 50.6 % of the irrigation potential of all Ethiopian rivers is in the Nile basin; besides, significant share of the population has no electric service (>60), no pure water access (42.7 %) and is below poverty line (29.6 %). Thus, the three countries need to be flexible for the 'give and take' principle-based negotiation and ensuring the equitable use of the Nile water.
