Irrigation

Irrigation is the artificial application of water to land or soil. It is a method which assists in the growing of agricultural products, maintenance of landscapes, andre-vegetation of disturbed soils in dry areas or during periods of inadequate rainfall. In recent times rainfall has changed its pattern causing inadequate rain water in many parts of the world, especially India. Additionally, irrigation also has a few other uses in crop production, which include protecting plants against frost, suppressing weed growing in grain fields and helping in preventing soil consolidation. In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dryland farming. Irrigation systems are also used for dust suppression, disposal of sewage, and inmining. Irrigation is also studied together with drainage, which is a natural or artificial removal of surface and sub-surface water from a specific area.

In the middle of the 20th century, the discovery of diesel and electric motors led for the first time to systems that could pump groundwater out of majoraquifers faster than it was recharged. This can lead to permanent loss of aquifer capacity, decreased water quality, ground subsidence, and other problems. The future of food production in such areas as the North China Plain, the Punjab, and the Great Plains of the US is threatened.

At the global scale, 2,788,000 km² (689 million acres) of agricultural land was equipped with irrigation infrastructure around the year 2000. About 68% of the area equipped for irrigation is located in Asia, 17% in America, 9% in Europe, 5% in Africa and 1% in Oceania. The largest contiguous areas of high irrigation density are found in North India and Pakistan along the rivers Ganges and Indus, in the Hai He, Huang He and Yangtze basins in China, along the Nile river in Egypt and Sudan, in the Mississippi-Missouri river basin and in parts of California. Smaller irrigation areas are spread across almost all populated parts of the world. Only 8 years later in 2008, the scale of irrigated land increased to an estimated total of 3,245,566 km², what is nearly the size of India.Hence ground water is a major concern and the world is running short of underground water.

Putting together need and resource will bring about a revolution in the field of Irrigation when water is transported to every nook and corner of India. Although it is an artificial method of providing water to grow crops, it is the need of the hour for India. Focus on transporting water will be our major goal. By helping the farmer we will help ourselves. Negara Infracon is taking projects to transport river water, reservoir water transported to such dry areas which are fertile for agriculture.
