Importance of monsoon rainfall in India's economic landscape

India is primarily an agrarian country. Agriculture is thus the backbone of its economy which is popularly known as a 'gamble in monsoon'.

In fact Monsoons are the life and soul of India's economic landscape particularly that of agriculture in determining cropping pattern. Over 200 cm rainfalls is ideal for the cultivation of rice, tea, jute.

100-200 cm: rice, wheat, sugarcane 50-100 cm: wheat, corn, pulses, etc.

Uncertainty in the arrival of monsoons proves disastrous for the health of the crops. It compels the farmer to look for means of irrigation, which may be convenient to him in that area.

Concentration of rainfall from July-September (3 months only) necessitates developing means of irrigation in order to grow rabi crops.

Excessive rainfall due to uncertain character of the monsoons may cause floods and result in havoc to life, land, crop and property.

The following are the main flood prone areas of the country:

(1) Basins of the rivers, which originate from the Himalayas.

Punjab, Haryana, Delhi, U.P, Bihar, Assam and West Bengal

(2) River basins of Peninsular India, Orissa, Tamil Nadu and Andhra.
