About this book

World population is set to increase by a third in the next 25 years, with no corresponding increase in global rainfall. About seventy per cent of the world's abstracted water is used in farming and therefore the economics of irrigation is becoming an increasingly important issue for sustainable development. Water for Agriculture provides a thorough overview of this highly topical subject, written in a clear and accessible style. The scope of the book is wide both in its analysis and in its geographical coverage. Topics covered include the infrastructure, operation and maintenance of irrigation service supply, the supply of drainage services, economic cost benefit analysis, water resource planning at the regional scale, political economy and irrigation policy. The content of Water for Agriculture is enhanced by numerous tables, diagrams, and in-depth case-studies. This book will be an essential read for those professionals involved in the planning of water resources, and for advanced students studying this topic as part of agriculture, development studies, economics, engineering, environmental science, geography, hydrology and planning courses.
