Book Synopsis A review of management strategies for salt-prone land and water resources in Iran by : Asad Sarwar Qureshi
Download or read book A review of management strategies for salt-prone land and water resources in Iran written by Asad Sarwar Qureshi and published by IWMI. This book was released on 2007-11-16 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately half of the irrigated area of Iran falls under different types of salt-affected soils and average yield losses may be as high as 50 percent. Slightly and moderately salt-affected soils are mostly found on the piedmonts at the foot of the Elburz (Alborz) Mountains in the northern part of the country. The soils having severe to extreme salinity are predominantly located in the Central Plateau, the Khuzestan and Southern Coastal Plains and the Caspian Coastal Plain. The process of salinization of the surface water resources is mainly due to natural conditions, and to a lesser extent, to the discharge of drainage water into the river systems. Estimates show that about 6.7 km3 of brackish water flow annually through 12 major rivers. There is no straightforward solution to the complex problems of salt-induced soil and water resources degradation in Iran. The approaches addressing the management of these resources need to be multidimensional and must take into account biophysical and environmental conditions of the target areas as well as livelihood aspects of the associated communities.

Book Synopsis Salinisation of Land and Water Resources by : Fereidoun Ghassemi
Download or read book Salinisation of Land and Water Resources written by Fereidoun Ghassemi and published by UNSW Press. This book was released on 1995 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human-induced salinisation is a major threat to the world's land and water resources. Inadequate development of irrigation projects, inefficient irrigation, lack of proper drainage, and environmental mismanagement such as the clearing of native vegetation, are responsible for the loss of millions of hectares of agricultural and grazing land, as well as the misuse of scarce water resources. The first part of this book analyses the problem in the context of the world's population, its climate and its land and water resources. It reviews irrigation methods and crop water requirements, the processes of salinisation, and its management. The second part describes irrigated land, dryland and water-resource salinity problems in 11 countries, which contain approximately 70 per cent of the world's irrigated land. In each case study, background data, environmental conditions and past management practices are given to provide an understanding of why salinity occurs in particular places, and of the management methods employed against it.
Book Synopsis Territorial Water Cooperation in the Central Plateau of Iran by : Majid Labbaf Khaneiki
Download or read book Territorial Water Cooperation in the Central Plateau of Iran written by Majid Labbaf Khaneiki and published by Springer. This book was released on 2018-11-09 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tries to answer the question how different communities in such an arid area as the Iranian central plateau could have shared their limited water resources in a perfect harmony and peace over the course of history. They invented some indigenous technologies as well as cooperative socio-economic systems in order to better adapt themselves to their harsh environment where the scarce water resources had to be rationed among the different communities as sustainably as possible. Those stories hold some lessons for us on how to adjust our needs to our geographical possibilities while living side by side with other people. This work gives insight into the indigenous adaptation strategies through the territorial water cooperation, and describes how water can appear as a ground for cooperation. It explains the water supply systems and social aspects of water in central Iran. Topics include the territorial water cooperation, qanat’s, the traditional water management and sustainability, the socio-economic context, the sustainable management of shared aquifers system and more.
Book Synopsis Management of Soil Problems by : Khan Towhid Osman
Download or read book Management of Soil Problems written by Khan Towhid Osman and published by Springer. This book was released on 2018-05-03 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are neither good nor bad, but some have inherent or acquired characteristics that may or may not suit our intended use. Unsuitable characteristics are considered to be soil problems, soil constraints or soil limitations. Only twelve percent of global land is right for agricultural production without much limitation. Some soils have severe limitations for crop production. These soils are so called ‘problem soils’. Many of them do not have enough fertility to be productive; some are arid and saline; some are very sandy and dry; and some are wet and waterlogged for most of the growing season. The global demand for food, wood, fuel, fiber, medicine and other plant products for the 7.2 billion current world population has created such an immense pressure on global soil resources that even the most fertile soils are losing their productive capacity. We are being compelled to bring more and more unsuitable or marginally suitable soils under cultivation. Unless innovative and integrated soil, crop and environmental management practices are adopted for their improvement and sustainable use, further degradation is inevitable. This book, Management of Soil Problems, identifies the problems and discusses management options in a smooth and reader-friendly style. It will be useful for students and professionals of soil science, agriculture, forestry, geography and environmental sciences.

This book was released on 2010-05-13 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Karkheh River Basin is the third largest basin in Iran after Karoon and Dez, and occupies a strategic position on the western boundary of the country. The basin has seen remarkable ancient feats of engineering, and has a long history of wheat and barley production, complemented by horticulture. With the growth of the modern nation-state of Iran, water development has progressed steadily in tandem with rising populations and urbanization. The report aims to understand the historical setting and present situation of water development and allocation, in relation to rural development and agrarian policy. It provides the contextual backdrop for further research on the management of water to improve livelihoods in the basin through integrated and sustainable management of land and water resources. It provides further information on the changes in surface flows out of the component subbasins and looks at the development, use and consequences of groundwater abstraction.
Book Synopsis Health impacts of small reservoirs in Burkina Faso by : Eline Boelee
Download or read book Health impacts of small reservoirs in Burkina Faso written by Eline Boelee and published by IWMI. This book was released on 2010-02-02 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Burkina Faso, at least 1,700 small reservoirs have been constructed, most of them during the last 30 years. Numerous and scattered, these beneficial multipurpose systems combine productive with domestic water uses. However, their environmental and health impacts remain insufficiently documented. This report combines data from different sources into syntheses and national maps, with a focus on water-related diseases. The mitigation of negative impacts requires an integrated approach to specifically identify the enhancing and limiting factors that influence environmental impacts and the transmission of diseases around reservoirs. Public awareness campaigns need to accompany the promotion of preventive and curative measures and the development of alternative water sources for domestic supply.
Book Synopsis Assessing the economic impact of redistributing water within a catchment: a case study of the Musi Catchment in the Krishna Basin in India by : Brian Davidson
Download or read book Assessing the economic impact of redistributing water within a catchment: a case study of the Musi Catchment in the Krishna Basin in India written by Brian Davidson and published by IWMI. This book was released on 2010-05-13 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim in this paper was to present the details of an economic modeling exercise conducted on the Musi Catchment of the Krishna Basin. The model has the unique characteristic of being able to value the water used on individual crops and in different regions. Thus, the individual values of water used to produce different crops, grown over two different seasons and over five very different regions within a catchment, were determined. This is a significant improvement over previous attempts, where a single value of water in a catchment was derived regardless of what it is used for, when it was used and where it used in the catchment. In addition to the agricultural valuation process, some account was made for the other uses of water and how they should be valued. The worth of these findings cannot be underestimated as the results are useful to those who need to allocate scarce water supplies between competing uses within a catchment. The assumptions underlying the model, the data used and the results and implications drawn are fully detailed in this paper. This model was connected to a hydrological model and used to simulate various scenarios on the water situation facing users in the basin. This model is the forerunner of similar modeling attempts on similar problems in other regions of the Krishna Basin and in the Murray Darling Basin of Australia.
