Irrigation development has been identified as a means to stimulate economic growth and rural development in Ethiopia. However, little attempt has been made to quantify the contribution of irrigation to national income. Using data from selected irrigation schemes, representing small, medium and large-scale schemes of modern or traditional typologies; the present coverage and planned growth of irrigation, actual and expected contributions of irrigation to the national economy were quantified following the approach of adjusted gross margin analysis. Our results show that irrigation yields 219.7% higher income compared to the rainfed system while its current and future contribution to agricultural GDP is estimated to be about 5.7 and 12% although irrigation covers about 5 and 9% of the total cultivated land area, respectively.

This manual (most of whose modules were originally published 2001-2002) aims at strengthening various aspects of irrigation development, mainly emphasizing the engineering, agronomic and economic aspects of smallholder irrigation, in view of the limited practical references available in this area. It also introduces the irrigation practitioner to the social, health and environmental aspects, providing a bridge between the various disciplines involved in irrigation development.--Publisher's description.

This book draws together the knowledge that has been gained in irrigation and drainage performance assessment over the last 10 to 15 yers. Performance assessment is an essential management task. If the use of water for irrigation is to be improved, then we must understand current levels of performance and identify measures for improvement. This book provides guidelines to enable practitioners to apply the process and procedures that have evolved. Developed by a working group of the International Commission on Irrigation and Drainage (ICID), it provides a theory and practice of how to audit and assess the performance of irrigation and drainage schemes. This book will be of interes to researchers and professionals in irrigation, drainage, soils and agricultural engineering.

India's irrigated agriculture sector has been basic to India's economic development and poverty alleviation. One of India's major achievements is its rapid expansion of irrigation and drainage infrastructure. However, the major emphasis on development has been achieved at a cost. The importance put on new construction has diverted attention away from the need to ensure the quality, productivity, and sustainability of the services. Further, a governmental subsidy based approach has been used and this has resulted in irrigation and drainage services which, while enabling significantly higher productivity than from non-irrigated lands, are well below their potential. 'The Irrigation Sector' discusses directions for future growth, the framework for reform, and the reform agenda.

The Handbook of Irrigation System Selection for Semi-Arid Regions compares the various types of available irrigation systems for different regions and conditions, and explains how to analyze field data to determine the suitability of the land for surface, sprinkle, or drip irrigation systems. The book focuses on strategies for irrigation development and management and examines deficit irrigation and partial root-zone drying systems. Also, solute leaching modeling under different irrigation systems, soil moisture conditions, and organic fertilizer application in arid areas are discussed. Further, it examines multi-criteria decision making for irrigation management and the appraisal of agricultural lands for irrigation in hot, sub-humid regions. Features: Presents comparative analysis to aid in the selection of the most appropriate types of irrigation systems according to land characteristics. Includes numerous practical case studies. Offers parametric evaluation systems for irrigation purposes. Considers data from semi-arid zones, each with different sub-climates. Focusing on semi-arid land, the book highlights parametric evaluation systems for irrigation purposes, along with the use of analytical hierarchy processes integrated with GIS to determine which systems are best suited. This comprehensive and well-illustrated handbook will be of great interest to students, professionals, and researchers involved with all aspects of irrigation in semi-arid regions.
