Résumé
Ethiopia is a populous country with a population of over 73 million people at the annual growth rate of 2.36 percent. The countrys economy is dominated by the agricultural sector, which contributes about 40 percent of the GDP and employs 80 percent of the labor force. Virtually all food crops come from rainfed agriculture with the irrigation sub-sector accounting for only about 3 percent of the food crops. However, rainfed crop production is unreliable and insufficient to support the ever increasing food demand in the country. Ethiopia is characterized by famine as a result of high population pressure, resource base depletion and an erratic rainfall pattern that affects the rainfed agriculture significantly. Presently, 50 percent of the population lives below the national poverty line. To overcome this problem the Government has given priority for irrigation development in the agricultural sector. Irrigation is therefore taken as an essential component and strategy for food security, to increase agricultural output by boosting up the productivity of smallholders, and crop diversification. This should be achieved by increasing command area of irrigated land and improving the performance of existing schemes. The aim of this research is to assess the performance of irrigation schemes in Ethiopia and benchmark by comparison with other similar schemes in other countries in order to identify the performance gap and then to make proposals and recommendations for the system improvement. The study followed the guidelines developed by International Programme for Technology and Research in Irrigation and Drainage (IPTRID) for benchmarking performance in the irrigation and drainage sector, 2001. Due to lack of organized database, based on standard benchmarking performance indicators, only five schemes from three countries including Ethiopia were used for comparison purposes. The result of the analysis shows that Balaqtar scheme of Egypt is performing relatively superior among others in terms of production per unit of land. Similarly, Goha W. scheme of Ethiopia is performing relatively superior among others in terms of production per unit of water supplied and consumed. However, this does not necessarily mean that either Balaqtar or Goha W. is performing better in all aspects. In case of Kulit and Goha W. schemes, even though the output per unit water supply is relatively better than other schemes, at present condition, water is not the scarce resource when compared to land. The output per unit of command area or cropped area is more pertinent in both schemes. Therefore, Balaqtar scheme of Egypt can be used as benchmarking against which these two schemes can contrast their productive performances. Generally, there was sufficient water supply for all schemes, with one scheme, Arata C., performing well in terms of matching supply to irrigation demand. The availability of water supply is therefore not a constraint to agricultural production. Expenditure on management, O&M costs varies markedly, with minimum and maximum expenditure per unit of water delivered was 0.0003 US$/m3 and 0.0014 US$/m3 in Kamala (Nepal) and Balaqtar (Egypt) schemes respectively. This means that Kamala scheme delivers water relatively cheaper than the other four schemes.
