    This publication deals with the underlying concepts relating to drainage water management. It first discusses the adequate identification and definition of the problem for the selection and application of a combination of management options. It then presents technical considerations and details on the four groups of drainage management options. The second part of the publication contains the summaries of the case studies from the United States of America, Central Asia, Egypt, India and Pakista n. These case studies represent a cross-section of approaches to agricultural drainage water management. The factors affecting drainage water management include geomorphology, hydrology, climate conditions and the socio-economic and institutional environment.

    Agricultural Drainage Water Management in Arid and Semi-Arid Areas 2002

    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: water conservation, drainage water reuse, drainage water disposal and drainage water treatment. All these options have certain potential impacts on the hydrology and water quality in an area, with interactions and trade-offs occurring when more than one is applied. This publication presents a framework to help make a selection from among the various drainage water management options and to evaluate their impact and contribution towards development goals. In addition, it presents technical background and guidelines on each of the options to enable improved assessment of their impacts and to fac ilitate the preparation of drainage water management plans and designs.
