Three decades of pastoralist settlement dynamics in the Ethiopian Omo Delta based on remote sensing data

Over the past three decades, pastoralist settlements in Ethiopia's Omo Delta have undergone significant transformation. Using remote sensing data and ground-truthing, researchers found that the inhabited area more than doubled from 1992 to 2009, with settlements becoming more permanent and concentrated in the northern part of the delta by 2019. This shift reflects a growing reliance on the Omo Delta for livelihoods, though it also highlights the impact of infrastructure investments on traditionally nomadic lifestyles. The study underscores the need for sustainable river basin management that accounts for downstream settlement patterns, particularly in light of dam operations like the Gibe III.
