Download or read book The Inter Relationship Between Irrigation Drainage and the Environment in the Aral Sea Basin written by M.G. Bos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The irrigated area in the Aral Sea basin totals about 7. 5 million hectare. Part of the water supplied to this area is consumed by the irrigated crop; the remainder of the supplied water drains to the groundwater basin, to downstream depressions, or back to the rivers. During its use, however, this drained part of the water accumulates salts and chemicals. The disposal of this polluted water causes a variety of (environmental) problems. If the percentage consumed water of the total water supply to an irrigated area (the so-called overall consumed ratio) can be increased, less water needs to be drained. This alleviates part of the related (environmental) problems. Further, if the overall consumed ratio for the above 7. 5 million hectare is improved, less water needs to be diverted from the rivers. Hence, more water can flow towards the Aral Sea. As mentioned above, part of the non-consumed irrigation water drains to the groundwater basin. Commonly, the natural discharge capacity of this basin is insufficient to handle this imported water. As a result, the groundwater table rises towards the land surface causing waterlogging. In (semi-)arid zones this waterlogging triggers a soil salinity problem resulting to a significant reduction in crop yields. The artificial increase of the discharge capacity, and lowering of the groundwater table, solves the soil salinity problem.

Download or read book The World Bank and Irrigation written by William I. Jones and published by World Bank Publications. This book was released on 1995-01-01 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
