Description

---

Salinisation of land and water is an increasing problem in many areas of the world, particularly in arid and semi-arid regions where irrigation is a contributory factor. This book assesses the extent, human causes and management of salinisation. The first part of the book provides an extended review of general issues, including a history of secondary salinisation, followed by a discussion of the trends in area irrigated, the process of salinisation, extent of land and water salinisation and their associated environmental, economic and social damages. Management options adopted by different countries are also discussed. The second and major part of the book then consists of chapters of case studies of individual countries, showing why salinity occurs in each one. The book is wide ranging in its scope and is aimed at senior students and research workers in geography, crop and soil science, irrigation engineering and environmental studies.
