Africa's largest hydropower facility is currently under construction on the main stem of the Blue Nile River in Ethiopia. Construction of the estimated $5 billion Grand Ethiopian Renaissance Dam (GERD) began in 2011 and is slated to be fully operational in late 2017. The GERD is poised to facilitate regional development with a 63 billion cubic meter reservoir and 6,000 MW of power generating capacity. Of keen interest to the water managers within the Nile River Basin is the transient filling stage of the massive reservoir. To date, however no reservoir filling rate policy has been established. This policy will have clear implications on the GERD's ability to generate hydropower in the near-term and coincidentally impact people and livelihoods in the downstream nations of Sudan and Egypt through reduced streamflow availability. Implications of climate variability and emerging climate change within Ethiopia cast further uncertainty on potential filling policies and system operations. To address this challenge, numerous filling policies are evaluated through a climate-sensitivity approach to estimate impacts on reservoir filling time, hydropower production, and downstream flows. This provides viable and timely points of comparison for regional water managers and politicians negotiating system operations in the midst of ongoing project construction.

This book is about the Grand Ethiopian Renaissance Dam newly being built on the Blue Nile, a transboundary river. Due to rising population and increasing water demand in the Nile basin, major projects raise interest and concern by millions with potential for water conflict. The dam design, reservoir filling policy, operation of the dam, riparian countries response, dam site importance and social impact and economy of the dam are presented in the book.

The World Water and Agriculture Model has been used to simulate water, hydropower, and food sector effects in Egypt, Sudan, and Ethiopia during the filling of the Grand Ethiopian Renaissance Dam reservoir. This unique capability allows tradeoffs to be made between filling policies for the Grand Ethiopian Renaissance Dam reservoir. This Nile River Basin study is presented to illustrate the capacity to use the World Water and Agriculture Model to simulate regional food security issues while keeping a global perspective. The study uses runoff data from the Intergovernmental Panel for Climate Change Coupled Model Inter-comparison Project Phase 5 and information from the literature in order to establish a reasonable set of hydrological initial conditions. Gross Domestic Product and population growth are modelled exogenously based on a composite projection of United Nations and World Bank data. The effects of the Grand Ethiopian Renaissance Dam under various percentages of water withheld are presented.

This book is a contribution by the presenters of the 2020 International Conference on the Nile and Grand Ethiopian Renaissance Dam (GERD). The Nile basin is facing unprecedented level of water right challenges after the construction of GERD has begun. Ethiopia, Egypt and Sudan have struggled to narrow their differences on filling and operation of the GERD. The need for science and data-based discussion for a lasting solution is crucial. Historical perspectives, water rights, agreements, failed negotiations, and other topics related to the Nile is covered in this book. The book covers Nile water claims past and present, international transboundary basin cooperation and water sharing, Nile water supply and demand management, Blue Nile/Abbay and Grand Ethiopian Renaissance Dam, land and water degradation and watershed management, emerging threats of the Lakes Region in the Nile Basin, and hydrologic variation and monitoring. This book is beneficial for students, researchers, sociologists, engineers, policy makers, lawyers, water resources and environmental managers and for the people and governments of the Nile Basin.

The Grand Ethiopian Renaissance Dam (GERD) will not only be Africa’s largest dam, but it is also essential for future cooperation and development in the Nile River Basin and East African region. This book, after setting out basin-level legal and policy successes and failures of managing and sharing Nile waters, articulates the opportunities and challenges surrounding the GERD through multiple disciplinary lenses. It sets out its possibilities as a basis for a new era of cooperation, its regional and global implications, the benefits of cooperation and coordination in dam filling, and the need for participatory and transparent decision making. By applying law, political science and hydrology to sharing water resources in general and to large-scale dam building, filling and operating in particular, it offers concrete qualitative and quantitative options that are essential to promote cooperation and coordination in utilising and preserving Nile waters. The book incorporates the economic dimension and draws on recent developments including: the signing of a legally binding contract by Egypt, Ethiopia and Sudan to carry out an impact assessment study; the possibility that the GERD might be partially operational very soon, the completion of transmission lines from GERD to Addis Ababa; and the announcement of Sudan to commence construction of transmission lines from GERD to its main cities. The implications of these are assessed and lessons learned for transboundary water cooperation and conflict management.

This unique volume discusses various aspects of the Grand Ethiopian Renaissance Dam (GERD) and the Aswan High Dam (AHD) including their positive and negative impacts. It presents up-to-date research findings by Egyptian scientists and researchers covering several interesting hot topics under the following main themes: · Major impacts of GERD compared with the AHD · Environmental impacts of the AHD · Modeling scenarios investigating the impacts of GERD on the AHD and downstream · Environmental and social impacts of GERD on Egypt · Status and assessment of the sediment of the AHD reservoir and modeling the impacts of GERD on Lake Nubia sediment accumulation · Proposed scenarios for maximizing the benefits of the AHD reservoir · International aspects of GERD and the AHD The volume also offers a set of conclusions and recommendations to optimize the cooperation between Egypt, Sudan, and Ethiopia. It appeals to postgraduate students, researchers, scientists, professionals and policy planners.

The effective and efficient management of water is a major problem, not just for economic growth and development in the Nile River basin, but also for the peaceful coexistence of the millions of people who live in the region. Of critical importance to the people of this part of Africa is the reasonable, equitable and sustainable management of the waters of the Nile River and its tributaries. Written by scholars trained in economics and law, and with significant experience in African political economy, this book explores new ways to deal with conflict over the allocation of the waters of the Nile River and its tributaries. The monograph provides policymakers in the Nile River riparian states and other stakeholders with practical and effective policy options for dealing with what has become a very contentious problem—the effective management of the waters of the Nile River. The analysis is quite rigorous but also extremely accessible.
