Question

Why is irrigation necessary in India?

Answer 1

Hint:The supply of water to land or crops, usually through channels, to aid development.
In dry areas and during times of less than normal rainfall, irrigation helps to grow agricultural crops, sustain landscapes, and re-vegetate disturbed soils. Monsoon is very erratic and cant depend on it.

Complete answer:
India is an agricultural country, so it requires a regular and adequate supply of water agriculture in India, depending primarily on monsoon rainfall, so it is seasonal uncertain and there are certain crops in heavenly distributed that require greater and regular water supply, such rice sugarcane additionally decides to increase the yield and post-production of crops that require regular water supply .
(1) Approximately 80 per cent of India's total annual rainfall occurs over four months, i.e. between mid-June and mid-October. It is therefore necessary to provide irrigation during the rest of the eight months for the development of crops, etc.
(2) Monsoons are unpredictable. So irrigation, as a result of uncertain rainfall, is important to protect crops from drought.
(3) In all parts of the world, it does not rain the same way. In less rainy areas, irrigation is therefore important for agriculture.
(4) The soils in some regions are sandy and loamy, and thus porous, for which a significant portion of the rainwater is very rapidly sinking. So, sandy and loamy soils, like alluvial soil and black soil, cannot hold water. That is why irrigation is essential in areas with sandy and loamy soils for agriculture.
(5) The rain-water flows down over the hillside slopes very rapidly. Irrigation is therefore required in such areas to grow crops.

Note:In 2030, 2,000 more cubic kilometres of water will be required each year to keep everyone fed, using today's irrigation methods. Around one-fifth of the overall energy use in India goes into the pumping of groundwater for irrigation. In India, over 263 million farmers and farm labourers are active in agriculture. It is the country's largest private company.
