Impact and Limitations — Prelims Strategy

Prelims Strategy

For Prelims success on Green Revolution impact and limitations, focus on memorizing specific data points: food grain production increased from 72 to 131 million tonnes (1965-81), wheat production from 12 to 45 million tonnes, Punjab's water table declining by 0.

5-1 meter annually. Remember the geographical concentration - Punjab, Haryana, western UP for wheat; Andhra Pradesh, Tamil Nadu for rice. Key personalities include M.S. Swaminathan (father of Indian Green Revolution) and Norman Borlaug (Nobel laureate).

Understand the technology package: HYV seeds + chemical fertilizers + pesticides + assured irrigation. For environmental questions, remember soil organic carbon declined from 0.8% to 0.3% in Punjab (1960-1990).

Practice elimination techniques by understanding that Green Revolution was geographically and crop-specific, not universal. Common traps include confusing Green Revolution with other agricultural programs, mixing up success and failure regions, and attributing wrong environmental impacts.

Focus on cause-effect relationships rather than just facts.
