UGC NET Questions (Paper – 1)

Statements B, C and D are correct because they show how environmental management and rural development are linked. Watershed projects support conservation and productivity, agroforestry offers multiple benefits while protecting resources and ignoring sustainability can degrade land and water in the long run. Statement A is incorrect as watershed programmes are not confined to infrastructure building but emphasise conservation and resource management. Hence, the combination containing B, C and D only is the correct answer.

Option A:
Option A is incorrect because it includes only B and C and omits D, even though D is a true statement about the risks of environmentally insensitive rural development strategies. Leaving out a correct statement results in an incomplete representation of the topic.

Option B:
Option B is correct because it captures all the true statements—B, C and D—and excludes the false claim in A. It acknowledges conservation benefits, agroforestry’s role and the need for sustainability in rural development planning, which together reflect the integrated approach promoted in the syllabus.

Option C:
Option C is incorrect because it includes statement A, which mischaracterises the objectives of watershed development. While B and C are correct, adding A means the option no longer represents only correct statements.

Option D:
Option D is incorrect since it asserts that all four statements are correct. Accepting A as correct would imply that watershed development is restricted to roads and markets, which contradicts its actual conservation focus. Therefore, the entire combination cannot be chosen.

Statements A, B, C, D and F are correct on goals, practices, chemical impacts, agroforestry and participation. Statement E is wrong because sustainable agriculture can use appropriate modern technology. Therefore A, B, C, D and F only is correct.

Option A:
Option A is incorrect because it omits F.

Option B:
Option B is incomplete because it omits A.

Option C:
Option C is incorrect because it includes E (false).

Option D:
Option D is correct because it includes A, B, C, D and F and excludes E.

Agroforestry systems integrate woody perennials with agricultural crops and sometimes livestock in spatial or temporal arrangements. This approach enhances biodiversity,improves soil fertility and provides multiple products for farmers. The stem defines exactly this combination of trees with crops or animals,making agroforestry the correct term.

Option A:
Monocropping means growing a single crop species on the same land year after year,often reducing biodiversity and resilience. It is the opposite of the diversified systems described in the question,so it is not appropriate here.

Option B:
Agroforestry can include practices like alley cropping,home gardens and silvopasture. These systems embody the integrated land use concept highlighted in the stem and show why Option B is the best match.

Option C:
Strip mining is a surface mining technique used to extract minerals and is unrelated to agricultural combinations of trees and crops. It generally leads to land degradation rather than ecological enhancement.

Option D:
Hydroponics is a method of growing plants without soil using nutrient solutions. Although innovative,it does not inherently involve trees or livestock on the same unit in the way agroforestry does.
