The multinational agreement is regulating the use of the Nile River’s waters has officially entered into force, despite strong opposition from Egypt.
The Nile Basin Initiative is a partnership of 10 riparian countries headquartered in Entebbe, Uganda.
The Nile is spanning 11 countries but only five countries signed and ratified the treaty.
Egypt and Sudan have yet to sign the agreement.
They both have long been embroiled in a dispute with Ethiopia over the Grand Ethiopian Renaissance Dam (GERD).
The GERD, a massive hydropower project on the Blue Nile, is providing electricity to Ethiopia’s 120 million citizens.
Egypt views the dam as an existential threat, as the Nile supplies 97 percent of its water needs.
The Nile Basin Initiative includes Burundi, the Democratic Republic of Congo, Egypt, Ethiopia, Kenya, Rwanda, South Sudan, Sudan, Tanzania, and Uganda, while Eritrea participates as an observer.
