Question

What is the river lift system?

Answer 1

Hint: Irrigation is the controlled application of water for agricultural purposes through man-made systems to meet water needs that are not met by rainfall. Crop irrigation is critical throughout the world to feed the world's ever-increasing population. Many different irrigation methods are used all over the world.

Complete answer:
A river lift system is one in which water is drawn directly from rivers to supplement irrigation schemes. River lift systems do not rely on the natural flow of water from rivers through canals, but instead, use other methods such as pumps and direct fetching. In areas where canal flow is irregular due to insufficient reservoir release, a river lift system may be used.

Lift irrigation schemes must accomplish two main tasks: first, they must transport water from the water source to the main delivery chamber, which is located at the highest point in the command area, using pumps or other means. Second, they must distribute this water to the fields of the benefiting farmers suitably and properly. As a result, in the Lift Irrigation system, the gravity flow of water by canals or rivers is not available or used.

Benefits of Lift Irrigation:
- Lift irrigation enabled irrigation at a higher level.
- The problem of land acquisition in L.I.S. is less severe.
- Water losses are minimal.
- Manpower is being used less frequently.

Note: Water is lifted from a lower level to a higher level in LI using pumps and other equipment. The construction of dams and canals greatly increased the irrigated area lying below the dam level, but the scarcity of water remained a problem for higher-level areas. L.I.S. is used to bring higher-level areas under irrigation. The irrigation in Maharashtra accounts for 8% of the total.
