प्रश्न
There is plenty of rain in India during the rainy season, yet we need irrigation. Give two reasons to support this statement.
उत्तर
Despite an adequate rainfall during the rainy season, we require irrigation because
- Rainfall is uncertain, irregular and unreliable in India.
- Distribution of rainfall in the country is uneven. While some states such as Kerala and Assam receive abundant rainfall during the monsoon months, Rajasthan and Haryana hardly receive any rainfall.
