      In many countries irrigated agriculture consumes a large proportion of the available water resources, often over 70% of the total. There is considerable pressure to release water for other uses, and as a sector irrigated agriculture will have to increase its efficiency and productivity of water use. Drawing on the author’s 30 years of experience. It emphasizes the management of irrigation as a business enterprise, moving management thinking out of traditional public sector mindsets to more customer-focused, performance-oriented service delivery. The book aims to provide practical guidelines to improve the three key processes of management, operation and maintenance of such systems.

        This book fills the need for an up-to-date comprehensive text on irrigation water management for students of agriculture both at the undergraduate and postgraduate levels. The scope of the book makes it a useful reference for courses in agricultural engineering, agronomy, soil science, agricultural physics and environmental sciences. It can also serve as a valuable guidebook to persons 5/5(4). A. The Role of Irrigation Water in Agriculture Systems 1.
