A lack of rainfall and increased droughts expected in East Africa means river flow could fall by 70 percent by 2100, according to UN forecasts.‘Those with the least water will have even less tomorrow’ At the southern end of the Nile, the impact of climate change is being felt keenly in Africa’s largest lake.Located between Kenya, Uganda and Tanzania, Lake Victoria is the largest supplier of water to the Nile, with the exception of rainfall.This would have a striking impact on the Nile, a river whose basin covers 10 percent of the African continent and which is an essential resource for 500 million people living in its vicinity.In countries such as Egypt and Ethiopia, lack of access to water among people living along the Nile is already an issue due to politics rather than climate change, says Ayeb."
