The book provides a comprehensive assessment of the law governing the use and management of the Nile and considers, more broadly, how international water law can guide the development of a legal and institutional framework for cooperation over shared freshwater resources. It defines the current state of international water law and discusses the content of the United Nations Convention on the Law of the Non-Navigational Uses of International Watercourses. On this basis, it assesses the Nile water treaties and the 2010 Cooperative Framework Agreement for the Nile, and examines their compliance with international law, with a specific focus on the legal consequences of South Sudan's secession from Sudan. Moreover, the book recommends important amendments to the 2010 Agreement. Building on these recommendations, it addresses the implementation of the principle of equitable and reasonable use regarding the Nile, illustrating the extent to which the principle can provide a conceptual framework for regulating water use. The book is a valuable resource for academics and practitioners alike as it combines legal assessment with a discussion of how international water law principles can be implemented in practice. "Essential reading for anyone interested in understanding international law related to the Nile River basin, including its evolution, current challenges and future prospects." - Professor Alistair Rieu-Clarke, Chair in Law, Law School, Northumbria University, Newcastle "A true must-read for anyone interested in the developing Nile River legal and institutional regime and in how to implement international water law principles and guidance at the transboundary river basin level. Most notably, the book operationalizes the principle of equitable use and applies it to the Nile, pointing the way forward for the cooperative management of the river's resources." - Stefano Burchi, Chairman of the Executive Council, International Association for Water Law (AIDA).
