UPSC Previous Year Question | Mains GS3 | 2020
How is science interwoven deeply with our lives? What are the striking changes in agriculture triggered off by the science-based technologies? (Answer in 150 words)
Answer
Introduction
Science shapes daily life through medicine, communication, transport, energy, sanitation, digital services and evidence-based public policy.
Agricultural Transformations
- High-yielding varieties, hybrid seeds, biotechnology and improved agronomy have raised productivity.
- Mechanisation has reduced drudgery and enabled timely sowing, harvesting and post-harvest operations.
- Drip irrigation, sprinklers, soil testing and micro-nutrients have improved input efficiency.
- Remote sensing, drones, GIS, weather advisories and mobile platforms support precision farming.
- Cold chains, food processing, improved storage and logistics reduce losses and expand markets.
Emerging Concerns
Excessive chemical use, groundwater depletion, monocropping, biodiversity loss, unequal access to technology and e-waste create sustainability and equity concerns. Smallholders need affordable, locally adaptable and climate-resilient solutions.
Conclusion
Science must therefore be combined with traditional knowledge, extension services and ecological safeguards to deliver productive, profitable and sustainable agriculture.
