Give a brief note on the following: (i) Sustainable agriculture (ii) Acid Rain
In short
Sustainable agriculture is climate-resilient farming that conserves soil and water, promoted by the National Mission for Sustainable Agriculture and Soil Health Cards. Acid rain forms when sulphur dioxide and nitrogen oxides from industry and vehicles mix with rain, lowering soil pH and damaging crops, aquatic life and the Taj Mahal.
Model answer
Ghissu Editorial · Verified 4 Oct 2026 · 233 words
Soil Health Card Scheme
Over 25 crore cards issued, enabling balanced fertiliser use to reduce soil degradation and pollution.
Pollution Control Regulations
BS-VI standards and real-time air quality monitoring address emissions of nitrogen oxides and sulfur dioxide, key acid rain precursors.
State-Level Integration
Andhra Pradesh combines national schemes with local extension services to promote sustainable farming and monitor acid rain impacts.
Adoption Barriers
Excessive fertiliser and pesticide use persists, especially in drought-prone Rayalaseema, undermining sustainability goals.
Acid Rain Impact
Lowers soil pH, harms crops, aquatic ecosystems, and monuments like the Taj Mahal, and causes heavy metal leaching into water.
Enforcement Gaps
Weak emission standard enforcement and low public awareness limit acid rain mitigation, especially in northern industrial belts.
Climate Change Effects
Altered rainfall and temperature extremes exacerbate challenges, highlighting the need for climate-resilient agroforestry practices4 such as those in drought-prone Karur.
