Environment & Ecology MCQs - 2026-03-30

Long-term benefits include enhanced soil fertility, reduced environmental degradation, improved farmer livelihoods, and greater resilience to climate shocks.

Potential short-term yield variations are identified as a challenge.

Smallholder farmers produce a significant portion of the world's food and are critical to sustainable agriculture efforts.

Precision agriculture optimizes the application of resources like water, fertilizers, and pesticides.

IPM uses a combination of methods to control pests, minimizing the use of harmful pesticides.

Conservation tillage minimizes soil disturbance, helping to retain soil moisture, reduce erosion, and sequester carbon.

Organic farming prohibits the use of synthetic pesticides and fertilizers.

Agroecology integrates ecological principles into farm design and management to enhance biodiversity and soil health.

Intensive monoculture is generally considered a conventional farming practice, not a sustainable one. Agroecology, organic farming, and conservation tillage are listed.

The shift is driven by the need to ensure food security and mitigate the environmental impact of conventional farming.
