Question

The need for irrigation in India is, to a large extent, influenced by the rainfall pattern of the country. Explain.

Answer 1

1. Rainfall is erratic: The amount and timing of rainfall vary from year to year, creating uncertainty in crop water availability.
2. Rainfall is unevenly distributed: Some regions, such as the Western Ghats and northeastern states, receive heavy rainfall, while others, such as Rajasthan and parts of the Deccan Plateau, receive very little.
3. Rainfall is seasonal: Most rain occurs during the Southwest Monsoon (June–September), leaving the rest of the year dry.
4. Certain crops need more water: Water-intensive crops like rice and sugarcane require continuous moisture, making irrigation essential where rainfall is insufficient.
