2. Monsoons cause rainfall only for three to four months in the year so for crops to grow water is required.

3. The distribution of rainfall in India is uneven and unequal. In some regions excess water causes floods while in others less water causes famines.

4. Irrigation is also important in arid regions.

5. Certain crops require more water than others so irrigation is required.
