The Nile basin has been embroiled in controversy ever since the late Ethiopian Prime Minister Meles Zenawi announced in February 2011 that Ethiopia would build the Grand Ethiopian Renaissance Dam (GERD), the largest hydroelectric power dam in Africa, on the Blue Nile immediately upstream of the Ethiopian-Sudanese border. Ethiopia, Sudan, and Egypt have still not agreed on arrangements for completing the filling and subsequent operation of the GERD.

This three-part lecture series on the GERD, hosted by MIT’s Abdul Latif Jameel Water and Food Systems Lab (J-WAFS), will be given by J-WAFS visiting scholar, professor Dale Whittington, Departments of Environmental Sciences & Engineering and City & Regional Planning, University of North Carolina at Chapel Hill. The lectures will explore the current controversy over the GERD; different ethical and political assessments of the project from the perspective of Ethiopia, Sudan, and Egypt; hydropower potential; irrigation withdrawals; and more. See below for details.

All lectures will be held from 4:00-5:00 p.m. ET, and light refreshments will be served starting at 3:45 p.m. The lectures will take place in the J-WAFS conference room, 292 Main Street, 3rd floor, Cambridge, MA 02142 (MIT building E38, suite 346). Guests may choose to attend all lectures, or individual ones.

**NOTE:

The lecture series is open to the MIT, Harvard, and Tufts communities only.

J-WAFS is committed to creating a welcoming, inclusive environment for all participants. If you need a disability-related accommodation to participate in our program, please email J-WAFS communications and program manager, Carolyn Blais at cblais@mit.edu. We look forward to having you participate in our program.

Lecture 1 – October 12, 2022 – Understanding the Nile Conflict: Contested Baselines

In this first lecture Whittington argues that the current controversy over the GERD can be best understood as a problem of “contested baselines.” The effect of a proposed or planned policy intervention such as a dam is estimated using a performance indicator that is associated with the difference between 1) a state of the world without the policy intervention, and 2) a state of the world with the policy intervention. Because the effects of most policy interventions play out over time, this comparison requires a forecast of the state of the world without the policy intervention (the “dynamic baseline”). If dynamic baselines are contested by stakeholders, controversy over the outcome of a policy analysis may be due primarily to different ethical or political assessments of the appropriate choice of the state of the world without the policy intervention. In this lecture Whittington describes Egypt’s “Cumulative Deficit Model” as an illustration of how Egypt perceives the “dynamic baseline” on the Nile and why Ethiopia has continually rejected this framing of the Nile conflict.

Lecture 2 – November 16, 2022 – The Risks and Rewards of the Blue Nile Cascade

As divisive as the construction of the GERD has been, another, arguably more consequential, controversy looms over the management of Nile. For decades water planners have envisaged not one large dam on the Blue Nile in Ethiopia, but a sequence or ‘cascade’ of several dams. This lecture presents the results of a river simulation model that includes a cascade of two additional large hydropower dams upstream of the GERD in Ethiopia. We have analyzed the hydropower potential of this reservoir cascade system and the system-wide implications for downstream riparians. As well as estimating hydropower generation, we examine scenarios in which Ethiopian irrigation withdrawals occur upstream of these dams and show the system-wide opportunity costs of such withdrawals. The analyses show how a cubic meter of water flowing downstream (adjusted for evaporation and seepage losses along the way), would generate hydropower multiple times in Ethiopia, as well as in Sudan and Egypt, before finally being used for irrigation in Egypt downstream of the High Aswan Dam. But this additional water storage upstream in Ethiopia creates new risks for the Nile riparians in terms of both filling and management of multi-year droughts.
