Arid Land Irrigation in Developing Countries: Environmental Problems and Effects covers the proceedings of the International Symposium on Arid Land Irrigation, held in Alexandria, Egypt on February This book is organized into eight sections encompassing 46 chapters. Get this from a library.

Salinity problems in arid lands irrigation: a literature review and selected bibliography. [Hugh E Casey; Water Resources Scientific Information Center.]. This book assesses the extent to which water resource problems were tackled in Developed Countries that may be unsuitable for Developing Countries today.

It examines water resource development and how water resources have evolved to embrace the ecological Water-related technologies for sustainable agriculture in arid/semiarid lands. In the Middle East, 20 × 10 6 hectares are affected by increased soil salinity, the reasons being poor irrigation practices, high evaporation rates, growth of sabkhas (salt scalds), and an increase in groundwater salinity.

Salinity problems in agriculture are usually confined to arid and semiarid regions where rainfall is not sufficient to transport salts from the plant root zone. Such areas comprise 25% of the earth’s surface (T horne and P eterson, ).Cited by:   Soil Salinity under Irrigation: Processes and Management - Ebook written by I.

What is irrigation salinity. Salinity is the accumulation of salts (often dominated by sodium chloride) in soil and water to levels that impact on human and natural assets (e.g.

plants, animals, aquatic ecosystems, water supplies, agriculture and infrastructure). Irrigation salinity occurs in irrigated landscapes (Figure 1). Improvement and Management of Soils in Arid and Semiarid Regions in Relation to Salinity and Alkali The development and maintenance of successful irri-gation projects involve not only the supplying of irri-gation water to the land but also the control of salinity and.

Dierickx ©Encyclopedia of Life Support Systems (EOLSS) The concentration of Na+, Ca2+ and Mg2+ in the saturation extract of a soil can easily be determined and SARse can then be calculated or read from the nomogram (Figure 2).

Salinization is the most striking effect of agriculture in all parts of the world. It results from natural and human activities, the latter including land clearing and excessive irrigation. Salinity due to such activities is called secondary salinity. The rising ground water during these activities dissolves salts that get deposited at or near the surface.

Soil salinity problems in Oman started to be noticed after the extensive agricultural activities followed by increase use of lands suitable for farming and overdraw of fresh groundwater to an.

In irrigation projects in (semi)arid zones and climates it is important to check the leaching requirement, whereby the field irrigation efficiency (indicating the fraction of irrigation water percolating to the underground) is to be taken into account.

The desired soil salinity level. Salinity problems reduce productivity on both irrigated and non-irrigated agricultural lands in the United States and throughout the world.

peterson, a. Especially the arid and semi-arid areas have extensive salinity problems. Waterlogging and salinization of soils are common problems associated with surface irrigation.

Waterlogging results primarily from inadequate drainage and over-irrigation and, to a lesser extent, from seepage from canals and ditches. 46 2 Soil Salinity: Historical Perspectives and a World Overview of the Problem (EAD), Middle East (Hussein ; Shahid et al. ), and Australia (Oldeman et al.

Salinity becomes a concern when an “excessive” amount or concentration of soluble salts occurs in the soil, either naturally or as a result of mismanaged irri-gation water. Worldwide, salt-affected soils are most abundant in arid regions, and in irrigated lands the File Size: 61KB.

Soil salinity is an enormous problem for agriculture under irrigation. In the hot and dry regions of the world the soils are frequently saline with low agricultural potential. In these areas most crops are grown under irrigation, and to exacerbate the problem, inadequate irrigation management leads to secondary salinization that affects 20% of Cited by: Agricultural losses caused by salinity are difficult to assess but estimated to be substantial and expected to increase with time.

Secondary salinization of agricultural lands is particularly widespread in arid and semiarid environments where crop production requires irrigation schemes. At least 20% of all irrigated lands are salt-affected. Salinity stress is one of the most vital abiotic stresses which results in significant damages of agricultural production, particularly in arid and semi-arid areas of the world.

Salinity causes by high accumulation of soluble salt, especially NaCl in soil and water. Salinity hampers the growth and survival of many field crops such as rice, wheat, maize, cotton, sugarcane, and : Sajid Hussain, Muhammad Shaukat, Muhammad Ashraf, Chunquan Zhu, Qianyu Jin, Junhua Zhang.He has published or presented more than 35 papers and one book in the areas of environmental geology, water resources, and coastal geomorphology.

He is a fellow of the Geological Society of America and the AAAS and is listed in the Directory of Arid Lands Research Scientists and in American Men and Women of by: 5.One of the main environmental problems which affect extensive areas in the world is soil salinity.
