(i) There are large variations in the amount of rainfall received in different parts of India. The highest amounts is received by the Northeastern states and Western Ghats and the rainfall is below 20 cm in Western Rajasthan. These large variations in actual amount of rainfall from year to year is known as variability of rainfall.
(ii) Agriculture is not possible without water. Large parts of India suffer from high rainfall variability. Without sufficient rainfall, agriculture in India is reduced to a gamble in the hands of monsoon. Kharif crops like rice and jute cannot be grown without sufficient rainfall. Productivity of agriculture is high with less variability of rainfall and vice versa.
