• Situation Analyses of Sediment Transport With a Focus on Its Management and Policy Implications

  A comprehensive analysis of sediment transport in Ethiopia's major river basins reveals significant variations in sediment yield, with the Abbay headwater subbasins and Awash upper and middle subbasins exhibiting exceptionally high values (200–233 t/ha/year and 115.76–47.47 Mt/year, respectively), while the Rift-Valley Lakes basin shows much lower yields (1.9–13.69 Mt/year). These findings highlight critical challenges to water quality, ecosystem health, and climate resilience due to excessive sediment concentrations that often surpass standards for drinking, irrigation, and aquatic life. The study identifies gaps in monitoring and proposes strategic interventions, including enhanced monitoring systems, stakeholder coordination, legislation, and integration of international initiatives like UNESCO's International Sediment Initiative. This research provides actionable insights for restoring land and water resources, emphasizing the urgent need to address sediment pollution to safeguard vital infrastructure such as the Grand Ethiopian Renaissance Dam and Rift Valley Lakes.

• Sediment transport and management in the river basins of Ethiopia: Challenges, strategies, and policy perspective

  Sediment transport in Ethiopian river basins, particularly the Abbay and Awash, exceeds safe thresholds for drinking water, aquatic protection, and irrigation, posing significant challenges to land and water resource management. The study reveals that erosion hotspots—such as North Gojjam, Beshilo, Jemma subbasins (Abbey Basin), and Kessemi, Nejaso Gera, Kebena (Awash Basin)—experience exceptionally high sediment yields (200–233 t/ha/year in Abbay; 115.76–47.47 million tons/year in Awash). In contrast, the Rift Valley Lakes Basin shows lower but still concerning levels (1.9–13.69 million tons/year). This research combines spatial analysis using QGIS with stakeholder interviews to identify erosion-prone areas and gaps in monitoring infrastructure, providing critical data for policy interventions, restoration efforts, and targeted land management strategies.

• Social structure and clan group networks of Afar pastorals along the Lower Awash Valley

  Afar pastoral societies along the Lower Awash Valley maintain a rigid social structure rooted in clan networks, customary law (maa'da), and traditional communication (dagu). These elements govern social interactions, enforce norms, and regulate behavior consistently across clans. The study found that while network ties facilitate intra-clan relationships, clan territories (dinto) remain fixed regardless of seasonal changes. However, urbanization, economic disparities, and drought have eroded mutual trust and weakened traditional norms. To preserve this sociocultural heritage, the research advocates for policy interventions to sustain traditional knowledge and social cohesion, benefiting Afar societies and broader stakeholders.

• Women's contributions versus Men's patriarchal status among Afar pastoralists in the Lower Awash Valley

  Afar pastoralist women, despite being excluded from leadership roles due to patriarchal norms, play crucial roles in maintaining social order, economic reciprocity, and resource sharing in the Lower Awash Valley. Their control over household responsibilities and income-generating activities is vital for the survival of Afar society. The study recommends integrating women's traditional roles into broader empowerment policies and removing sociocultural barriers to enhance their contributions to pastoral livelihoods. This research used qualitative methods—situational observations, key interviews, and group discussions—to analyze women's unrecognized but essential functions in socio-economic interactions and clan networks.

• Punishing criminals indigenously: Perspectives from customary law and social relationship practices of Afar pastorals along the Lower Awash Valley

  Customary law among the Afar pastoralists of Ethiopia's Lower Awash Valley offers non-adversarial approaches to justice that could serve as models for broader legal systems. The study, employing qualitative methods such as deep interviews and focused group discussions, reveals how traditional practices balance social structures while facing challenges from statutory laws, Sharia, and state-imposed regulations. Traditional courts struggle with enforcement, and there is debate over codifying indigenous law, which risks erosion by younger generations. These findings highlight the potential for integrating Afar customary practices into mainstream justice systems to enhance fairness and reform.

• Isotopic insights into the Early Acheulean (1.95 Ma–1.66 Ma) high-elevation paleoenvironments at Melka Kunture (Upper Awash Valley, Ethiopia)

  Stable isotope analysis of fossil fauna tooth enamel from two Early Acheulean sites, Garba IVD (1.95 Ma) and Gombore IB (1.66 Ma), at Melka Kunture in Ethiopia's Upper Awash Valley reveals that all analyzed taxa were grazers consuming C4 plants, indicating extensive mountain grasslands during the Pleistocene. Oxygen isotope results further distinguish between semiaquatic and terrestrial habitats, aligning with faunal taxonomy and pollen data. While Garba IVD suggests a continuous open landscape, Gombore IB shows interruptions by forests and bushy vegetation, highlighting discrepancies in environmental reconstructions using different proxies. This study underscores the resilience of dietary strategies among Early Pleistocene taxa across varying elevations in eastern Africa.

• Early Pleistocene large mammals from Maka’amitalu, Hadar, lower Awash Valley, Ethiopia

  Research at Maka’amitalu, Hadar, in Ethiopia’s lower Awash Valley, reveals significant species turnover in large mammal faunas during the Early Pleistocene (~2.4–1.9 Ma), with a small but diverse assemblage of 20 taxa. Unlike older deposits (e.g., Hadar Formation and Ledi-Geraru), this fauna shows subtle shifts in dietary proportions, body size, and bovid abundances, suggesting a constant rate of turnover over time. Biochronological analysis supports the age estimate from Bouroukie Tuff 3 (BKT-3). The study highlights the paleoecological and evolutionary significance of the region, contributing to our understanding of mammalian evolution in eastern Africa.
