The correct answer is: A) Surface water
Telangana’s irrigation potential is primarily derived from surface water. The state has a vast network of rivers, canals, and reservoirs that provide water for irrigation. In 2019, surface water accounted for 87% of Telangana’s irrigation potential.
Groundwater is also a significant source of irrigation in Telangana. In 2019, groundwater accounted for 13% of the state’s irrigation potential. However, groundwater is becoming increasingly scarce due to overexploitation.
Rainfall harvesting is a small-scale method of collecting rainwater for irrigation. It is not a significant source of irrigation in Telangana.
Here is a brief explanation of each option:
- Surface water is water that flows on the surface of the Earth, such as in rivers, lakes, and streams. It is the primary source of irrigation in Telangana.
- Groundwater is water that is stored underground in aquifers. It is a significant source of irrigation in Telangana, but it is becoming increasingly scarce due to overexploitation.
- Rainfall harvesting is a small-scale method of collecting rainwater for irrigation. It is not a significant source of irrigation in Telangana.
