The many billions of dollars invested in canal irrigation in recent decades have had disappointing results. Rarely have projected benefits in well-being or production been achieved. In consequence, in the mid-1980s, further vast sums are being spent throughout the Third World on programmes for rehabilitation, canal lining, on farm development, and farmers' organisation. In this book, Robert Chambers shows that much of this policy and practice is based on misleading research and misdiagnosis. When applied to the complexity and uniqueness of canal irrigation systems, the normal professionalism of civil and agricultural engineers, agronomists, economists, and sociologists, leaves gaps which are keys to better performance. In successive chapters, five such gaps are analysed and presented: main system management, including the scheduling and delivery of water, and communications; canal irrigation at night; management of canal systems jointly by farmers and officials; professional conditions and incentives for irrigation managers; and methods for diagnostic analysis to identify cost-effective actions for improvement. Managing Canal Irrigation has been written for policy-makers, irrigation managers, consultants, researchers, trainers and teachers. It challenges all concerned with improving the performance and anti-poverty impact of canal irrigation, whether in government departments, aid agencies, consultancy firms, training and research institutes or universities, to re-examine their beliefs, biases and actions. By going beyond the limits of normal professionalism, the book presents a new syllabus for training, a new agenda for research and development, and points to new policies and to practical action to be taken in the field.
