The Lower Most Omo River sub-watershed in Ethiopia is facing a growing crisis—one that could have dire consequences for local communities and infrastructure, including energy projects. A new study by Magisa Yohannes of Hawassa University’s Institute of Technology, published in *Discover Environment*, reveals how shifting land cover is accelerating riverbank erosion and flooding, with commercial implications for the energy sector.
Using Landsat-derived Normalized Difference Vegetation Index (NDVI) and Modified Normalized Difference Water Index (MNDWI) models integrated with GIS, Yohannes and his team mapped land cover changes from 1995 to 2025. The findings are stark: water bodies have expanded by 153.76 km², while bare land and forest cover have declined by 392.59 km² and 290.77 km², respectively. Shrubland, however, has increased by 529.59 km²—a shift that weakens riverbank stability.
“This isn’t just an environmental issue; it’s an economic one,” Yohannes warns. “Without intervention, Omorate town could be entirely submerged in just over three years, and the Omo River bridge—critical for regional trade and energy transport—could follow in eight. That’s a direct threat to hydroelectric projects and supply chains.”
The study highlights a 5.125 km²/year flooding rate, driven by backwater from Lake Turkana, which now endangers the Dasenech woreda. The energy sector, particularly hydropower and irrigation-dependent industries, must take note. Sustainable land-use planning and early-warning systems—leveraging NDVI-MNDWI models—could mitigate risks before costly disruptions occur.
As climate variability and human activity reshape river systems, this research underscores the urgency of adaptive infrastructure strategies. For stakeholders in East Africa’s energy market, the message is clear: monitor, model, and act—before the river does.
