Using a nexus approach to support development and environmental planning in Ethiopia

The document outlines a collaborative project using the SEI nexus toolkit—integrating the Water Evaluation and Planning (WEAP) and Long-range Energy Alternatives Planning (LEAP) systems—to analyze trade-offs and synergies in Ethiopia's upper Blue Nile region. Initial findings indicate that while increased irrigation can reduce water for hydropower and the environment, optimized dam operations can meet both energy and environmental goals. Additionally, the study highlights a link between energy transitions and agriculture, noting that shifting away from traditional biomass could improve soil productivity.

• Initial modelling results for the Lake Tana and Beles River basins identify a trade-off where increased water withdrawals for upstream irrigation may decrease water availability for downstream environmental requirements and hydropower generation.
• The analysis suggests that energy production goals and environmental flow requirements can both be met through small adjustments to hydropower dam operation rules, although this may result in slightly higher inter-annual variations in energy production.
• There is a documented link between agricultural productivity and energy sources; the use of traditional biomass for cooking causes a loss of nutrients and organic matter in agricultural soils, while agricultural intensification requires more energy for mechanization, irrigation, and fertilizer production.
• Social network analysis conducted as part of the project indicates a necessity for benefit-sharing mechanisms and bridging institutions across different scales and sectors.
