"Assessing impacts of irrigation expansion on Ethiopian households" by Ehjeij, Simon Abstract Ethiopia’s agricultural sector is mainly based on rainfed agriculture, despite large water resources in form of river basins and groundwater potential. It is believed that irrigation development plays a crucial role to improve the country’s food security situation through increasing annual cropping periods, make use of improved seeds and other inputs, and stabilizing fluctuations of rain-dependent agricultural systems, which gains importance in the face of climate change. This study aims at assessing the potential impacts of different expansion strategies for irrigation technologies in Ethiopia on agricultural production, household incomes, and ultimately, the country’s food security situation. In the analysis, special focus is put on small-scale and subsistence production while considering variations on a sub-national level. A CGE model is employed to provide the link between water usage and irrigation possibilities on the production side, and changes in household incomes on the consumption side of the economy. Irrigation is incorporated into the production technology of the CGE model by disaggregating agricultural activities into irrigated and non-irrigated activities, using data on different production technologies and studies on input use for irrigated and rainfed household farms in Ethiopia. Irrigation expansion is then simulated using different scenarios depicting a gradual increase in irrigation expansion and a variation in costs of irrigation expansion. Agricultural output is assessed via changes in yield and production mix, factor and intermediate input use. The food security situation of households is evaluated via incomes, food expenditure shares, and food prices. This work aims to derive implications for Ethiopian households and the country’s agricultural sector resulting from further agricultural development by means of extending the use of the country’s large water resources. |
