Answer 2

Answer:

Irrigation in India includes a network of major and minor canals from Indian rivers, groundwater well based systems, tanks, and other rainwater harvesting projects for agricultural activities. Of these groundwater system is the largest.In 2013-14, only about 36.7% of total agricultural land in India was reliably irrigated, and remaining 2/3rd cultivated land in India is dependent on monsoons.65% of the irrigation in India is from groundwater.Currently[when?] about 51% of the agricultural area cultivating food grains is covered by irrigation. The rest of the area is dependent on rainfall which is most of the times unreliable and unpredictable.

Irrigation in India helps improve food security, reduce dependence on monsoons, improve agricultural productivity and create rural job opportunities. Dams used for irrigation projects help produce electricity and transport facilities, as well as provide drinking water supplies to a growing population, control floods and prevention droughts.
