“…This study noted that limited abilities, skills and knowledge of farmers in operation and maintenance of the scheme affected the efficiencies at the scheme. These results concur with the findings of Dejen et al [19] and Ulsido [20] who found out that limited trainings on irrigation water management leads to low performance of an irrigation scheme. Yami and Snyder [21] extended that farmers' trainings in irrigation water management are crucial in ensuring sustainable irrigation development.…”

This study evaluated the water delivery performance of Nkhafi irrigation scheme based on adequacy, water delivery efficiency, equity, dependability and irrigation efficiency. Primary data were collected from field measurements, scheduled interviews, group discussions and use of a structured questionnaire. CROPWAT 8.0 computer model was used to determine crop water requirements and irrigation requirements. The results revealed that adequacy, water delivery efficiency, equity, dependability and overall water delivery performance were (0.74; 0.82), (0.70; 0.80), (0.15; 0.20), (0.11; 0.21) and (0.80; 0.80) for 2017 and 2018 seasons respectively. The scheme overall irrigation efficiencies were 20% and 25% for 2017 and 2018 respectively. These findings revealed that scheme users failed to deliver adequate and dependable water in an effective manner in both growing seasons. This occurred due to insufficient water supply, poor irrigation scheduling, lack of adequate knowledge and skills in operating and rehabilitating hydraulic structures, siltation and water losses through seepage in canals. Therefore, it is recommended that major maintenance works need to be done along the whole canal network in order to achieve good overall water delivery performance. Furthermore, farmers need to be trained in water management, sustainable agricultural production practices, operation and maintenance of irrigation structures. The study has provided an insight on the status of the scheme hence encouraging scheme users to improve water delivery performance.

“…Irrigation practices in the nation are mainly traditional [20] and range from medium to large-scale. Small-scale irrigation is not well practiced in the nation [21]. However, small-scale irrigation plays an important role in maximizing food production and contributing towards food security in Ethiopia and other Sub-Saharan countries [22][23][24][25][26][27].…”

Abstract:The study was conducted in Lake Tana Basin of Ethiopia to assess potentially irrigable areas for home gardens, water availability, and feasibility of water-lifting technologies. A GIS-based Multi-Criteria Evaluation (MCE) technique was applied to access the potential of surface and groundwater sources for irrigation. The factors affecting irrigation practice were identified and feasibility of water-lifting technologies was evaluated. Pairwise method and expert's opinion were used to assign weights for each factor. The result showed that about 345,000 ha and 135,000 ha of land were found suitable for irrigation from the surface and groundwater sources, respectively. The rivers could address about 1-1.2% of the irrigable land during dry season without water storage structure whereas groundwater could address about 2.2-2.4% of the irrigable land, both using conventional irrigation techniques. If the seven major dams within the basin were considered, surface water potential would be increased and satisfy about 21% of the irrigable land. If rainwater harvesting techniques were used, about 76% of the basin would be suitable for irrigation. The potential of surface and groundwater was evaluated with respect to water requirements of dominant crops in the region. On the other hand, rope pump and deep well piston hand pump were found with relatively the most (26%) and the least (9%) applicable low-cost water-lifting technologies in the basin.

“…Studies in the Rift Valley Lake Basin of Ethiopia showed that soil salinity/acidity, waterlogging, and communicable and noncommunicable diseases were the main limitations as well as depletion of water, and continuous maintenance needs and inefficient water management were the challenges of small scale-irrigation. Such factors meant the production gain from irrigated agriculture was below the expected value (Ulsido et al, 2013;Ulsido and Alemu, 2014). Consistent problems were also observed in Namibia (Fiebiger et al, 2010).…”

The potential of smallholder-irrigated agriculture to enhance food security and improve livelihoods has led the government of Ethiopia to invest significantly in irrigation establishment. This article aims to investigate the impact of small-scale irrigation on households' livelihood. To deal with the problems of purposive targeting and self-selection which are likely to occur for this type of intervention, we use a sophisticated econometric technique called 'propensity score matching' to study this impact. Our findings confirm the presence of a statistically significant difference in income, overall expenditure, asset accumulation and expenditures on agricultural inputs between the treated and control households. In contrast, no statistically significant differences in livestock resources, food consumption, and expenditure on education and health were found. Furthermore, the proportion of poor is respectively 20 and 30% for the treated and control households. So, overall it can be concluded that participation in the small-scale irrigation has robust and positive effect on most of the livelihood indices and that an expansion of irrigation schemes is a good strategy in the water-stressed and drought-prone areas of Ethiopia.

RÉSUMÉLe potentiel de l'agriculture irriguée à améliorer la sécurité alimentaire et améliorer les moyens de subsistance des petits exploitants a conduit le gouvernement éthiopien à investir de manière significative dans l'établissement d'irrigation. Cet article vise à étudier l'impact de l'irrigation à petite échelle sur les moyens de subsistance des ménages. Pour faire face aux problèmes de ciblage téléologique et d'auto-sélection qui sont susceptibles de se produire pour ce type d'interventions, nous utilisons une technique économétrique sophistiqué appelée score de propension pour étudier cet impact. Nos résultats confirment la présence d'une différence statistiquement significative dans le revenu, les dépenses globales, l'accumulation d'actifs et des dépenses sur les intrants agricoles entre les ménages traités et de contrôle. Nous n'avons par contre pas trouvé de différence sur ressources en cheptel, la consommation alimentaire et les dépenses d'éducation et de santé. En outre, la proportion de pauvres est respectivement 20 et 30% pour les ménages traités et de contrôle. Donc, dans l'ensemble, on peut conclure que la participation à l'irrigation à petite échelle a un effet robuste et positif sur la plupart des indices de subsistance et que l'expansion des systèmes d'irrigation est une bonne stratégie pour gérer les stress hydrique et la sécheresse régions d'Ethiopie.
