TL;DR: Sterl et al. as discussed by the authors show that the multiple political and environmental challenges that surround the Grand Ethiopian Renaissance Dam could be mitigated by explicitly coupling its operation to variable solar and wind power, which would create an incentive for Ethiopia to retain a seasonality in the Blue Nile flow.
Abstract: Ethiopia, Sudan and Egypt are currently embroiled in a politically charged conflict that surrounds the soon-to-be-completed Grand Ethiopian Renaissance Dam (GERD), with Ethiopia’s energy objectives purportedly conflicting with the water needs in Sudan and Egypt. Here we show that the multiple political and environmental challenges that surround GERD could be mitigated by explicitly coupling its operation to variable solar and wind power, which would create an incentive for Ethiopia to retain a seasonality in the Blue Nile flow. We found that this could deliver fivefold benefits across the three countries: decarbonizing power generation in the Eastern Africa Power Pool; allowing compliance with Sudan’s environmental flow needs; optimizing GERD’s infrastructure use; harmonizing the yearly refilling schedules of GERD and Egypt’s High Aswan Dam; and supporting a strong diversification of Ethiopian power generation for domestic use and for Eastern Africa Power Pool exports. These results argue for an explicit integration of complementary hydro, solar and wind power strategies in GERD operation and Eastern Africa Power Pool expansion planning. The Grand Ethiopian Renaissance Dam will be hugely beneficial to Ethiopia, but has raised tensions with neighbouring countries that rely on flow from the Blue Nile. Sterl et al. present scenarios for dam operation coupled with solar and wind power generation that could mitigate some of these concerns.

TL;DR: A novel energy, water and food nexus ‘Node’ methodology is introduced which concludes that the critical factors that increase risk in open field farms are weather factors, such as temperature, solar radiation and humidity, whilst groundwater factors have the highest impact on conventional and hydroponic greenhouses.

TL;DR: In this article, the authors analyzed gridded daily rainfall data over the period 1981-2020, used photographs and satellite images to depict flood areas and threats, compiled and studied flood-related statistics over the past two decades, and supported the results with peer-reviewed literature.

TL;DR: In this paper, the authors performed a temporal analysis of nine water-energy nexus indicators for hydropower generation and irrigation water pumping in the Lower Blue Nile, a major tributary of the Nile within Sudan.

TL;DR: In this article, the authors introduce a new modeling framework that simulates the Nile River System and Egypt's macro economy, with dynamic feedbacks between the river system and the macroeconomy, to compare water resources management strategies for the Nile in a quest for efficient use of the river's limited and stressed water resources.
Abstract: The landscape of water infrastructure in the Nile Basin is changing with the construction of the Grand Ethiopian Renaissance Dam. Although this dam could improve electricity supply in Ethiopia and its neighbors, there is a lack of consensus between Ethiopia, Sudan, and Egypt on the dam operation. We introduce a new modeling framework that simulates the Nile River System and Egypt’s macroeconomy, with dynamic feedbacks between the river system and the macroeconomy. Because the two systems “coevolve” throughout multi-year simulations, we term this a “coevolutionary” modeling framework. The framework is used to demonstrate that a coordinated operating strategy could allow the Grand Ethiopian Renaissance Dam to help meet water demands in Egypt during periods of water scarcity and increase hydropower generation and storage in Ethiopia during high flows. Here we show the hydrological and macroeconomic performance of this coordinated strategy compared to a strategy that resembles a recent draft proposal for the operation of the dam discussed in Washington DC. Integrating river system and economy-wide models in a dynamic, iterative, bidirectional fashion allows assessing some economic impacts of interventions in river systems. Here the authors use this framework to compare water resources management strategies for the Nile in a quest for efficient use of the river’s limited and stressed water resources.
