Some of the steps taken under smart farming are:
1) Raising livestock - Farmers in addition to growing crops, raise livestock to add to their income.
2) Drip irrigation - This is a smart way of irrigation which directly supplies water at the roots of the plants and avoids water wastage.
3) Rainwater harvesting - The rain water falling on roofs of houses is collected in a tank with the help of pipes and is used later for different purposes.
