The ecological sustainability of Indira Gandhi Canal Project is questioned because of increased _________.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Waterlogging and soil salinity
Heavy canal irrigation and excessive use of water in the dry command area brought waterlogging and soil salinity. In the long run these hamper the sustainability of agriculture.
NCERT (2026-27): “Irrigation in Stage-I command area of the canal was introduced in early 1960s, whereas, the command area of Stage-II began receiving irrigation in mid-1980s. … The availability of soil moisture for a longer period of time and various afforestation and pasture development programmes under CAD have resulted in greening the land. This has also helped in reducing wind erosion and siltation of canal systems. But the intensive irrigation and excessive use of water has led to the emergence of twin environmental problems of waterlogging and soil salinity.” “Measures for Promotion of Sustainable Development … The ecological sustainability of Indira Gandhi Canal Project has been questioned by various scholars.” |
