Ongoing pressures from population growth, recurrent drought, climate, urbanization and industrialization in the Nile Basin raise the importance of finding viable measures to adapt to these stresses. Four tributaries of the Eastern Nile Basin contribute to supplies: the Blue Nile (56%), White Nile-Albert (14%), Atbara (15%) and Sobat (15%). Despite much peer reviewed work addressing conflicts on the Nile, none to date has quantitatively examined opportunities for discovering benefit sharing measures that could protect negative impacts on downstream water users resulting from new upstream water storage developments. The contribution of this paper is to examine the potential for mutually beneficial and sustainable benefit sharing measures from the development and operation of the Grand Ethiopian Renaissance Dam while protecting baseline flows to the downstream countries including flows into the Egyptian High Aswan Dam. An integrated approach is formulated to bring the hydrology, economics and institutions of the region into a unified framework for policy analysis. A dynamic optimization model is developed and applied to identify the opportunities for Pareto Improving measures to operate these two dams for the four Eastern Nile Basin countries: Ethiopia, South Sudan, Sudan, and Egypt. Results indicate a possibility for one country to be better off (Ethiopia) and no country to be worse off from a managed operation of these two storage facilities. Still, despite the optimism of our results, considerable diplomatic negotiation among the four riparians will be required to turn potential gains into actual welfare improvements.

A considerable amount of research in the field of International Relations (IR) has acknowledged the interplay between domestic politics and foreign policy. Few studies, however, have investigated this phenomenon in the narrower field of transboundary water politics. There is also a general lack of research exploring how the formation of a national identity can overlap with the construction of a large hydraulic infrastructure, and how this can have repercussions at the international level. This paper draws on Robert Putnam’s (1988) two-level game theory to illustrate how the interrelation between the domestic and the international dimensions matters in transboundary water politics. Perspectives from IR, political geography, and water politics serve to present a conceptual framework which is then linked to studies on nationalism. This helps to highlight the analytical relevance of such a perspective to understand the issue of large dams. The paper takes the cases of the Grand Ethiopian Renaissance Dam in Ethiopia and the Rogun Dam in Tajikistan as examples.

This article employs a hydro-economic optimization model to analyze the effects of the Grand Ethiopian Renaissance Dam on the distribution and magnitude of benefits in the Eastern Nile. Scenarios are considered based on plausible institutional arrangements that span varying levels of cooperation, as well as changes in hydrological conditions (water availability). The results show that the dam can increase Ethiopia’s economic benefits by a factor of 5–6, without significantly affecting or compromising irrigation and hydropower production downstream. However, increasing GERD water storage during a drought could lead to high costs not only for Egypt and Sudan, but also for Ethiopia.

Study region: Eastern Nile River Basin (Ethiopia, Sudan and Egypt).
Study focus: This study aims to understand the future water development perspective in the Eastern Nile region by considering the current water use situation and proposed reservoirs in the upper Blue Nile (Abbay) River basin in Ethiopia using a simulation approach. The study was carried out by using a monthly time step and historical ensemble time series data as representative of possible near future scenarios. Series of existing and proposed cascaded water development projects in the upper Blue Nile were considered in the study.
New hydrological insights for the region: The results indicated an overall energy gain in the Eastern Nile region increases by 258%. The upstream country Ethiopia can generate as much as 38200 GWh/year of Energy while the energy production in Sudan increases by 39%. The cascaded developments integrated with existing water resources systems have a performance efficiency of above 92%. This study was an indicative analysis of the potential benefit of upstream Nile development without significantly affecting existing development in the Nile Basin. Further scientific analysis in this direction would help the Nile countries to reach a water use agreement.

Establishing cooperation in transboundary rivers is challenging especially with the weak or non-existent river basin institutions. A nexus-based approach is developed to explore cooperation opportunities in transboundary river basins while considering system operation and coordination under uncertain hydrologic river regimes. The proposed approach is applied to the Nile river basin with a special focus on the Grand Ethiopian Renaissance Dam (GERD), assuming two possible governance positions: with or without cooperation. A cooperation mechanism is developed to allocate additional releases from the GERD when necessary, while a unilateral position assumes that the GERD is operated to maximize hydropower generation regardless of downstream users' needs. The GERD operation modes were analysed considering operation of downstream reservoirs and varying demands in Egypt. Results show that average basin-wide hydropower generation is likely to increase by about 547 GWh/year (1%) if cooperation is adopted when compared to the unilateral position. In Sudan, hydropower generation and water supply are expected to enhance in the unilateral position and would improve further with cooperation. Furthermore, elevated low flows by the GERD are likely to improve the WFE nexus outcomes in Egypt under full cooperation governance scenario with a small reduction in GERD hydropower generation (2,000 GWh/year (19%)).

Infrastructure in river basins is essential to achieving several Sustainable Development Goals (SDGs), including SDG 2 on zero hunger, SDG 6 on water and sanitation, and SDG 7 on affordable and clean energy. However, important tradeoffs and synergies need to be navigated across these goals as both water and resources for infrastructure investments are limited. In transboundary river basins, such tradeoffs can transcend countries, creating a complex, interconnected system of water-energy-food linkages. With increasing pressures on the Blue Nile’s water resources from population and economic growth and climate change, an analytical framework for joint planning of these essential human development goals at a fine temporal resolution and considering multi-national priorities can enhance the potential to achieve water, energy, and food security. In this study, we develop and apply a framework for water resources planning in the Blue Nile using four steps: (1) understanding the water-energy-food nexus management landscape through stakeholder engagement and literature review; (2) developing a detailed daily simulator that captures major nexus components and objectives at a fine temporal scale; (3) linking the simulator to an Artificial intelligence-based search algorithm to design efficient agricultural and dam operation portfolios considering national and sectoral priorities; and (4) presenting the results using interactive visualization tools to facilitate dialogue and support decisions. Our results identify efficient operation plans for large dams on the Blue Nile for alternative cropping patterns in expanded irrigation areas in Sudan that minimize tradeoffs across water, energy, and food objectives.
