  • About the Edition

    The papers review the present use of irrigation systems for fisheries in the countries of the arid belt of Asia, from Turkey to China. They deal with the following countries and areas: Xinjiang Uygur Autonomous Region (China), India, the Islamic Republic of Iran, Kazakhstan, Kyrgyzstan, Mongolia, Pakistan, Turkey and Uzbekistan. While some countries in the arid belt are well advanced in the field of fish production from waterbodies of irrigation systems, others are experiencing major difficulties arising from recent changes in their political and economic systems, particularly Mongolia and the countries of Central Asia.

    Abstract. Flood-based farming systems (FBFS) are extensively used throughout Sub-Saharan Africa. Consisting of spate irrigation, flood recession and flood rise farming, inundation canals and depression agriculture, it is estimated that these farming systems cover close to 25 million hectares in . Increased groundwater recharge stems from the unavoidable deep percolation losses occurring in the irrigation scheme. The lower the irrigation efficiency, the higher the losses. Although fairly high irrigation efficiencies of 70% or more (i.e. losses of 30% or less) can occur with sophisticated techniques like sprinkler irrigation and drip irrigation, or by well managed surface irrigation, in.

    Abstract. Karez system is considered as the global human heritage since it is not only a traditional water supply system of exploiting groundwater, but also it reflects the culture, socio-economy, and history of the ancient civilizations that had utilized them for thousands of years in arid and semi-arid . 3 hours ago  In the debate over grazing in the West, there’s a trend toward magical thinking. In “If you like fish and birds, hug a cow,” a Writers on the Range column from ranchers Pat and Sharon O’Toole, both indulge in unscientific flights of fantasy, claiming that irrigation and livestock are beneficial for native fish and wildlife. Unlike cows, native wildlife in the West don’t need arid.

    A field trial was conducted with maize cultivar Zhengdan in Wuwei of Gansu, China from April to October , to study the effects of different irrigation systems on soil moisture and yield of maize for seeds in the northwest arid areas. The irrigation mode mainly affected soil water distribution of cm layer at the seedling stage. Agrilinks is an online community for food security and agricultural development practitioners.

The step by step procedure of. Irrigation and Irrigation Systems: An Overview Irrigation, the addition of water to lands via artificial means, is essential to profit-able crop production in arid climates. Irrigation is also practiced in humid and sub-humid climates to protect crops during periods of drought.

Irrigation is prac. Drainage cannot solve salinity buildup problems under all circumstances because relatively dry monsoons provide insufficient leaching water, and salts added by tubewell irrigation can only be evacuated from the soil profile if the drainage system is very intense.

Reduced irrigation inputs is a proper short-term solution, although wheat. planning, designing, evaluating, and managing irrigation systems.

These areas receive relatively low overall amounts of precipitation in the form of rainfall or snow (UN, ; MEA ). During the Soviet period, the expansion of the area under irrigation began in the s but even after the second world war rates of expansion were not very high.

Inthe total irrigated area amounted to × 10 6 ha of Central Asia. Up tothe rate of irrigation expansion slightly exceeded % per year. Irrigation and Agricultural Development compiles selected papers presented at the International Expert Consultation held in Baghdad, Iraq from February 24 to March 1, This book addresses the technical, economic, and institutional problems connected with the development and utilization of irrigation water for agricultural production.

This paper applies a metaheuristic algorithm named the firefly algorithm (FA) to reservoir operation and demonstrates the superiority of this algorithm against the genetic algorithm (GA), a commonly used optimization algorithm, using (1) five mathematical test functions, (2) the operation of a reservoir system with the purpose of irrigation.

Land reclamation by irrigation is, however, not limited to desert regions. Much of the land irrigated in humid areas throughout the world is used for the production of paddy rice, although irrigation of vegetable crops, usually with overhead sprinkler systems, also is practised on a considerable acreage.

Arid and semi-arid lands make up more than 80 per cent of the country’s land mass and are home to approximately 36 per cent of its population.

These areas have the highest incidence of poverty. The agriculture sector remains the backbone of the Kenyan economy, employing 80 per cent of the rural population and accounting for about 65 per cent.

Irrigation is the process of applying controlled amounts of water to plants at needed intervals. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall.

Irrigation also has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil. Agriculture and irrigation in arid lands: From a viewpoint of sustainability Part 1: Irrigated agriculture in arid lands The irrigated agriculture which utilize river or groundwater are often introduced to arid lands because of the scarcity of annual rainfall.

In case of Pakistan in West Asia, irrigation. Evapotranspiration is critical to many applications including water resource management, irrigation scheduling, and environmental studies. Many models based on meteorological data have already been developed to estimate reference evapotranspiration (ET 0) in various climatic and geographical conditions.

The main purpose of this study was to evaluate the performances of the .Impact of salinisation of surface waters caused by irrigation and diversion of drainage waters on fisheries in Amudarya and Syrdarya Rivers basins, Central Asia.
