1. Increase in food production: Increase in crop yield leads to an increase in food production, thus developing people as well as society
2. Protection against drought: The provision of adequate watering facilities in any region ensures protection against failure of crops from famines and droughts.
3. Revenue generation: When the regular supply of water is assured, the farmers can grow certain superior or high priced crops in place of inferior or low priced crops. As a result, revenue is generated.
4.Mixed Cropping: Means growing two or more crops together in the same field. This practice is followed so that if weather conditions are not favourable for one crop, it may be suitable for other crops. But if enough water facilities are made available, the need for mixed cropping is eliminated
