About 70% of the irrigation in Rajasthan is from:-
- A.Ponds and Lakes
- B.Taps and tube wells
- C.Nadi and Bawdi
- D.Rivers and Canal
Correct answer
Explanation
The correct answer is B, wells and tube wells. Although the Indira Gandhi Canal and the Chambal canals are the famous works of the state, they water only a part of it. Across Rajasthan as a whole the greater share of the irrigated area, close to seventy per cent, is served by wells and tube wells sunk by farmers themselves, which is exactly why the falling water table is the central farming problem of the state and why sprinkler and drip systems are pushed so hard here.
Option A is wrong because ponds and lakes irrigate only a small tank irrigated pocket, mostly in the south east. Option C names the nadi and the bawdi, which are traditional village ponds and stepped wells kept for drinking water rather than for watering fields. Option D, rivers and canals, is the second largest source and is concentrated in Sri Ganganagar, Hanumangarh, Kota, Bundi and Baran, but it stays well below the share of wells.
