Salinity Management for Sustainable Irrigation: Integrating Science, Environment, and Economics (Environmentally and Socially Sustainable Development. Rural Development)
Editorial Reviews
Book Description
Irrigation is the supply of water to agricultural crops by artifical means, designed to permit farming in arid regions and to offset drought in semi-arid regions. Irrigation has long played a key role in feeding expanding populations and is expected to play a still greater role in the future. Inevitably, however, irrigation entails the addition of water-borne salts which accumulate and induce the self-destructive twin phenomena of water-logging and salination. Moreover, this often negatively affects adjacent lands and water resources.
Is irrigation sustainable, and if so, how and under what conditions? That is the question that has impelled the writing of this book, which attempts to select and organize the disparate facts into a unified exposition, combining physico-chemical, agronomic, environmental, and economic principles into practical recommendations.
Chapters include: The Nature of Salinity, Effects on Crops, Irrigation Water, Waterlogging and Drainage, Salinity Control, Early Warning Systems, Scaling up from the Field, and a Conclusion which addresses directly the question of whether or not irrigation is sustainable. An appendix covers the economic aspects of salinity management.
