In a village, farmers pump out ground water faster than rain can recharge it. Which problem does this add to, and which rule of Herman Daly for sustainable development does it break?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Land degradation; the rate of extraction of renewable resources should not exceed the rate of regeneration
Taking out ground water in excess of the recharge capacity is one of the factors of land degradation. Water is a renewable resource, and Daly says the rate of extraction should not exceed the rate of regeneration. Pumping faster than rain recharges breaks this rule.
Option (1) Land degradation; the rate of extraction of renewable resources should not exceed the rate of regeneration — Correct. Both parts are right.
Option (2) Ozone depletion; the rate of extraction of renewable resources should not exceed the rate of regeneration — Incorrect. The rule is right, but ozone depletion comes from chlorine and bromine compounds, not from using ground water.
Option (3) Land degradation; technological progress should be input efficient and not input consuming — Incorrect. The problem is right, but the case is about over-extraction, not about the kind of technology used.
Option (4) Global warming; inefficiencies arising from pollution should be corrected — Incorrect. Pumping ground water is not given as a cause of global warming, and the case is not about pollution.
NCERT (2026-27): “7.3 State of India’s Environment … Some of the factors responsible for land degradation are (i) loss of vegetation occuring due to deforestation … (ix) improper planning and management of irrigation systems (x) extraction of ground water in excess of the recharge capacity (xi) open access resource and (xii) poverty of the agriculture-dependent people.” “7.4 Sustainable Development … (iii) renewable resources should be extracted on a sustainable basis, that is, rate of extraction should not exceed rate of regeneration (iv) for non-renewable resources rate of depletion should not exceed the rate of creation of renewable substitutes …” |
