The issue then for Egypt, among other countries in the Nile Basin, is whether this project will decrease water flow in the Nile. The Nile Basin Initiative, Egypt's civil society, and foreign relations are a few of the main contributors to the historical and social framework Egypt's hydro-politics and environmental concerns.
The 340-kilometer (211-mile) Jonglei Canal was first imagined in the early 1900s by Anglo-Egyptian colonial authorities to increase the Nile’s outflow towards Egypt in the north.
