Irrigation and drainage can improve or degrade ecosystems and the environment. Problems associated with irrigated agriculture include erosion, sedimentation of surface waters, chemical and nutrient contamination of water supplies, and salinization. Too, water and chemical inputs for urban and recreational irrigation are often far higher than. , was entitled "Salinity Problems in Arid Lands Irrigation: A Literature Re- view and Selected Bibliography." As pointed out in the Foreword to Number 1, "The historic role of the OALS. The need to use seawater in irrigation. There are about million hectares of coastal desert land in the world, where about 17% (about 50 million hectares) is level 0% slope lands, it’s suitable for irrigated agriculture (in terms of soil type, the land slope, and there is no competition for the other uses), and it’s expected that the land will increase the irrigated areas in the Author: Hani Abdelghani Mansour, Ren Hongjouan, Hu Jiandong, Bao Hong Feng, Liang Changmei. Soil salinity is the major environmental stress and largely causes yield losses of crops worldwide. This problem is more acute in arid and semi-arid regions (Munns, ), where salinity strongly limits crop development. In the Senegal River, irrigation water is mixed to native neutral saline waters.

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 Salinity problems in arid lands irrigation book 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. In addition, productivity of the irrigated lands of the Euphrates basin (Syria, Iraq) is seriously constrained by by: 5.
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 Salinity problems in arid lands irrigation book 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. Salinity problems in arid lands irrigation book 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 Salinity problems in arid lands irrigation book 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 Salinity problems in arid lands irrigation book and non-irrigated agricultural lands in the United States and throughout the world. Salt-affected soils on Colorado range land. High annual evaporation (and/or transpiration), low annual precipitation and restricted soil drainage, combine to create salt affected soils in depressions or.

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.

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.

[E Barton Worthington] -- Arid Land Irrigation in Developing Countries. 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. Soil salinization is a problem associated with irrigation in arid and semi-arid environments.

Is irrigation sustainable, and if so, how and under what conditions. That is the question that has impelled the writing of this by: The expansion of irrigated agriculture is required to feed the ever-increasing world population. On the other hand, the expansion of irrigated agriculture causes waterlogging and salinization problems in semiarid and arid regions where more than three-fourths of the world’s population reside.
Chapter 4F: Irrigation Water Management Soil-Water-Plant Relationships Effective and efficient irrigation begins with a basic understanding of the relation-ships among soil, water, and plants.
Figure 4f-2 illustrates the on-farm hydrologic cycle for irrigated lands, and Table 4f-1 provides definitions of several terms associated with irrigation. The potential role of halophytes in the management of salinity problems of arid lands is investigated at length nowadays; some of these produced promising forage crops.
This volume focuses on reclamation, management, and utilization of salt-affected soils, their sustainable use, and evaluation of plants inhabiting naturally occurring saline.
Deficit irrigation is the cause of most salinity related problems in the Arizona turf industry. A deficit irrigation regime is defined as one in which water applied to turfgrass via irrigation and precipitation is inadequate to maintain soil salinity at levels that support optimal turf performance (Fig.

Since the lands surrounding the Aral Sea have become independent republics, a number of missions have reported on the water-related environmental problems in the basin. Such reports have contributed to a plan of action for solving or alleviating some of the problems identified, high priority being accorded to improving the irrigation efficiency.
gated lands and effluent from city sewage and industrial waste water can impact water quality. In most irrigation situations, the primary water quality concern is salinity levels, since salts can affect both the soil structure and crop yield.
