The ground water utilisation is very high in the states of Punjab, Haryana and Tamil Nadu because these states are advanced agricultural states.
Water is used mainly in irrigation. The share of agriculture sector in total water utilisation is much higher than other sectors. Irrigation is needed because of Spatio-temporal variability in rainfall in the states. The large tracts of the country are deficient in rainfall and are drought prone. Further, the high yielding varieties of crops need regular moisture supply, which is made possible only by a developed irrigation systems.
