    PERFORMANCES OF INSTITUTIONAL AND IRRIGATION MANAGEMENT ACTIVITIES IN MAI-GOBO IRRIGATION SCHEME, EASTERN ZONE OF TIGRAY
    (Mekelle University, 2025-03-25) SEMERE W/GERIMA
    This study evaluates the performance of institutional and irrigation management activities at the Mai-Gobo Sand Storage Dam in Tigray, which operates at only 50% of its design capacity, focusing on irrigation practices, water use, control structures, and organizational activities to identify challenges and propose corrective measures. Data collected from nine experimental fields (upper, mid, and downstream) and 15 irrigation beneficiaries through interviews, key informant interviews, and focus group discussions were analyzed using the CROPWAT 8.0 model for crop water requirements and SPSS for statistical analysis. The results revealed significant inefficiencies in irrigation scheduling, water distribution, and conflict management by the water user association, with the water supply varying drastically across crop growth stages, showing a 92.8% oversupply during the initial stage and a 70.5% supply gap during the late season stage. Yield reduction was primarily attributed to disease damage (73.3%) and water shortages (26.7%), while major challenges included adverse weather conditions (floods and wind), pest infestations, lack of extension services, low crop yields, poor management, insufficient agricultural inputs, unfavorable market prices, and limited access to capital. Respondents recommended corrective measures such as improving extension services, ensuring timely input distribution, providing better technical support, strengthening institutional arrangements, enhancing market systems, promoting mechanization, and facilitating access to credit to address these challenges and improve the sustainability and efficiency of irrigation management at Mai-Gobo Sand Storage Dam in Tigray. The researcher also recommended that government institutions and development partners take the lead in promoting collaborative efforts to support small-scale irrigation initiatives using Sand Storage Dams in water-scarce areas.
