Book Description
Modern Land Drainage 2nd edition is a fully revised and updated edition of the 2004 edition. Modern Land Drainage describes traditional drainage formulas (Hooghoudt, Kirkham, Donnan, Ernst, Glover-Dumm) for rainfed agriculture in the humid temperature zone. Significant parts are devoted to drainage for salinity control of irrigated land in (semi-) arid zones, and to drainage of rice land in the humid tropics. Institutional, management and maintenance aspects are extensively covered, as well as the mitigation of adverse impacts of drainage interventions on the environment. The latest computer applications for drainage design in the context of integrated water management are described (DRAINMOD, HEC, SWAP, etc.). Field surveys are executed by governments, with the aid of consultants, but rarely are the end stakeholders (i.e., farmers and general public) involved from inception to planning to execution of a drainage system. Yet, during the Operation, Management and Maintenance (OMM) phase of a water management system, they are expected to takeover, run, bear and be responsible for the costs of OMM. The book describes successful methodologies and processes to be followed for engagement of stakeholders at all levels, from government to farm, from minister to farmer, and, from beginning to end. The book covers all aspects needed for sustainable drainage. The latest survey methodologies with satellites and drones are suggested to assess cause and effect. Waterlogging and salinity are the effect of something caused most likely upstream of the drainage problem location. Hence treating the cause may be more cost-effective. Triple Bottom Line (social, environmental and financial considerations) and the water-food-energy nexus are an integral part of the drainage design process. Controlled drainage, i.e. the balance of removal and conservation of drainage water and minimising solute transport as low as reasonably achievable (ALARA principle) is extensively described. This work is intended for use both as a university level textbook and as a professional handbook; it is of particular value to professionals engaged in drainage development in the context of integrated water resources and river basin management, civil and agricultural engineers, government officials, university students and libraries.

Book Description
The complex of ecological problems in Central Asia, especially in Uzbekistan, is linked to rapid ongoing demographic and economic processes. However, geographical location has its own peculiarity. Aridity of the climate in Uzbekistan makes water resources as main limiting factor for sustainable economic development (Chub et al., 1998; RECCA, 2011). Annual precipitation, ranging from 80-200 mm in plain to 300-400 mm in foothills and 600-800 mm in mountain rangelands (Chub, 2007), is considerably lower than the evaporation demand of atmosphere (FAO IPTRID et al., 2004). Thus, agriculture, accounting about 90% withdrawal of total available water resources in Uzbekistan, is impossible without irrigation (Qadir et al., 2009). Moreover, agricultural production is highly vulnerable to climate change (Lioubimtseva & Henebry, 2009). High fluctuation of precipitation and temperature increase may influence land use in irrigated lands, create difficulties in water management at regional and local scales, and increase competition of scarce water resources among water users in various sectors.
