Agricultural drainage water management in arid and semi-arid areas

the long version

"This publication provides planners, decision-makers and engineers with guidelines to sustain irrigated agriculture and at the same time to protect water resources from the negative impacts of agricultural drainage water disposal. On the basis of case studies from Central Asia, Egypt, India, Pakistan and the United States of America, it distinguishes four broad groups of drainage water management options: water conservation, drainage water reuse, drainage water disposal and drainage water treatment."--P. [4] of cover.
