The following are the three reasons in support of the given statement:
1. Well-developed irrigation facilities have lessened the dependency of peasants on monsoon by ensuring regular supply of water.
2. The development of proper irrigation facility has enabled peasants to grow the water-intensive and commercial crop.
3. The development of tube wells, irrigation pumps in the farming land has enabled peasants to irrigate a large plot of land.
The following are the effects of developing proper irrigation facilities:
1. This has resulted in brininess of the earth.
2. It has increased productivity.
3. The development of irrigation facilities has resulted in changing the cropping pattern, for instance, rice, which was earlier grown in Northeastern India due to heavy rainfall; the production of rice now can be seen in the areas of low rainfall such as Punjab, Haryana and parts of Rajasthan.
