India is located in the Asian subcontinent with a total area of 2.95 million square kilometers and arable land of 2.73 billion mu, of which about 2.4 billion mu have been cultivated. In addition to drought in the northwestern part of India, rainfall is generally abundant, with a national annual runoff of 1,675 billion cubic meters. The total length of the river is 42,000 kilometers and the water resources reserves are 41 million kilowatts.
