“…The three demand conditions were tested for the unilateral and cooperation conditions together with the case of no GERD. A drought policy for the High Aswan Dam (HAD) was also applied in all the simulations (Donia 2013;Hamed 2018). The policy applies a sliding fraction reduction to the downstream demands based on the storage level at the HAD, Table 2.…”

Water-food-energy nexus for transboundary cooperation in Eastern Africa

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%)).

“…For example, the design of the high-water spillway of a hydroelectric power plant applies the laws of hydrodynamics, and the retention of water in the lake behind the dam is managed by the function of the hydrological regimes, the intended use of water downstream of the power plant, and the needs of the society for electrical power [41].…”

Ideal-Type Narratives for Engineering a Human Niche

Abstract:Humans have built an anthropocentric biogeosphere; called: 'human niche'. Global change is part of this historical process of niche construction, which implies the intersection of the biogeosphere and the sphere of human activities of social, economic, cultural, and political natures. To construct these intersections, modern-day societies deploy 'engineered systems' and build narratives to frame these activities with purpose. This essay describes: (i) perceptions of what 'engineered systems' are about, (ii) their context such as global change, human agency, and societal implications of applied geosciences, and (iii) related narratives on how to handle global change through the design of 'engineered systems'. Subsequently, regarding underpinning insights, it is shown that they: (i) are well-known, were used in the past, and now may be applied to handle global change; (ii) enshrine a distinct choice on how human activities and the biogeosphere shall intersect; and (iii) can be described by a simple ideal-type scheme, which does not require detailed scientific-technical understanding. Subsequently, it is illustrated how this ideal-type scheme leads to different narratives about what kind of 'engineered systems' are preferred. It is concluded that such ideal-type narratives for a messy world may help a lay-public to choose between options regarding how to handle global change.
