[WLRC, December 2025] A seminar titled “Water–Energy–Food (WEF) Nexus Modeling: Sharing Experience for Science-Based Planning for Ethiopia” was held on 9 December 2025 at the WLRC Meeting Hall. The seminar was presented by Dr. Semu Moges, a senior hydrologist and Associate Professor at the University of Connecticut. During the seminar, Dr. Semu shared his experience with national-scale applications of the WEF Nexus in Ethiopia, emphasizing the importance of integrated and science-based planning for achieving the Sustainable Development Goals (SDGs) by 2030. He reflected on Ethiopia’s resource base and examined whether it possesses the necessary conditions to meet the SDGs. He also explored how sustainable development performance can be assessed through WEF-related indicators and what it would take for Ethiopia to ensure long-term water, energy, and food security without compromising its natural resource base. In his presentation, Dr. Semu explained the use of the Climate, Land, Energy, Water, and Socioeconomic (CLEWS) modeling framework, illustrating how WEF systems can be synthesized through interactions among climate, land use, energy systems, water resources, and socioeconomic drivers. He stressed that the effectiveness of WEF Nexus approaches increases significantly when ecosystem variables are integrated into the analysis. Dr. Semu noted that Ethiopia’s predominantly rural economy continues to pose substantial challenges to meeting the SDGs. He also pointed out that rapid urbanization carries its own risks if it is not supported by the resources necessary for sustainable growth. He emphasized that scientific evidence and integrated planning tools like CLEWS are essential to guiding the country along a sustainable development pathway. As a way forward, WLRC and Dr. Semu would explore potential for collaboration in the area. For that purpose, Dr. Semu would draft a concept note by factoring the ecosystem into the WEF nexus. The seminar was attended by WLRC colleagues, including Director General Dr. Gete Zeleke and other scientists, who engaged in discussions on how WEF Nexus modeling can inform national and regional development strategies.
