Résumé partiel
The Government of Ethiopia has made a strong commitment to developing and expanding various types of irrigation systems, technologies, and institutions among smallholder farmers. As a result, the irrigated area in the country has substantially increased over the last three decades. Today, a variety of irrigation technologies and institutional arrangements can be found in the country. However, it remains unclear which institutions and irrigation technologies and combinations are most effective for rural growth, poverty alleviation, and environmental sustainability.

This thesis seeks to address these issues through assessing the economics of irrigation in Ethiopia. Starting from exploring the institutional arrangements for irrigation water management at federal, regional and local levels, the study investigates the role of multiple types of irrigation management systems and irrigation technologies in influencing three factors central to irrigation’s future in the country : profit generation, farmers’ empowerment and environmental sustainability. The research implemented using a mixed methods approach, including a unique and comprehensive household and plot level survey conducted in ten districts of the country in 2016/17, as well as qualitative data collected through focus group discussions in the same area. The data are further enriched with Landsat images and climate variables (for period 1981-2016) that are linked to geo-referenced household and plot level latitude and longitude coordinates.

A nested approach is used as an analytical framework to examine the existing institutional arrangements related to irrigation water development and management. The findings show that even if the policies, strategies, and the legal instruments are well specified, and the relevant institutions and organisations have been established, there has been weak enforcement capacity, overlaps in mandates, duplication of efforts and absence of an integrated system of information and resources management among organizations at each administrative level.
