Includes introduction to the contributors.

Land Drainage – Principles, Methods and Applications presents the latest information, concepts and technology for ensuring sustainable agricultural production and environmental management by adopting land drainage measures. It focuses on a subject, central to the sustainability of irrigated agriculture. The authors’ considerable field work experience and strong grip on the subject are pivotal in conceptualizing this book. This book provides an explicit description of the subject for students as well as the practicing engineers in this area. A logical sequence is followed in the presentation of chapters, beginning with the occurrence of drainage problems, their causes, remedies, design and execution of drainage systems and the benefits of drainage. The book can claim to be the only comprehensive title on the subject in India. SALIENT FEATURES 1. Follows an application-centric approach based on mathematical and statistical concepts 2. Provides a global scenario of drainage by studying different drainage models 3. Discusses drainage in the Indian context 4. Text is supported by statistical inputs and well illustrated examples 5. Includes self-assessment questions with answers and a number of solved and unsolved problems 6. Includes case studies of Drainage and Salt Management

This Edited Volume Deals With Earth-Its Conservation, Management Of Natural Resources, Agriculture, Livestock And Water Resources Development. It Is Divided Into Five Parts-Natural Resources-Sustaible Livestock Development-Sustainable Agriculture-Policies-Foundation Day Lectures. Advocates Strategies Needed To Save Mankind And Our Planet In The New Millennium.

Annotation This book provides an independent and comprehensive review of World Bank irrigation lending and policy between 1948 and 1993. The Bank's role in irrigation lending has been large--more than $30 billion (in current U.S. dollars) spread over some 600 projects. Only 200 projects have been in place long enough to be assessed. The overall performance record is good, but there is room for improvement.The report finds that there are still pervasive problems in maintenance and operation. Operating chaos prevails in most large canal systems in the humid tropics. In drier areas, drainage is the biggest environmental problem associated with irrigation. The author argues for upgrading existing systems, improving service, involving irrigators, and saving water where it is scarce.

Reliable subsurface drainage systems for groundwater table and salinity control are needed to maintain or enhance the productivity of irrigated lands and to contribute to the rural development of lowlands in the humid tropic. This publication presents guidelines to assess the need for envelopes and for the selection of appropriate materials (i.e. pipes and envelopes) for the proper and lasting performance of subsurface drainage systems. In addition, it also contains guidelines for adequate installation and maintenance of drainage materials as well as the required specifications and standards of such materials, which may be used in tender documents for implementation of subsurface drainage works. Practical guidelines for the implementation of laboratory and field investigations to evaluate the performance of drainage materials have also been included.--Publisher's description.
