1.India's Green Revolution Legacy (Agricultural Revolution)
What & Where
Green Revolution: 1960s science-policy push using HYV seeds, fertilisers, mechanisation to raise cereal yields.

Quick Facts for MCQs
Drivers
- Food insecurity post-Independence; population boom needing self-reliance.
- Economic sovereignty sought by cutting costly grain imports.
- National security linked to stable domestic food supply.
Technologies & Inputs
- HYV seeds paired with urea, DAP, pesticides raised per-hectare yields.
- Tube-wells, electric pumps, tractors accelerated double-cropping.
- MSP procurement ensured market uptake of surplus grain.
Environmental Impact
- Over-irrigation depleted aquifers; water table dive in Punjab, Haryana.
- Chemical overuse triggered soil nutrient imbalance, declining organic carbon.
- Monoculture replaced traditional millets, eroding agrobiodiversity.
Socio-Economic Issues
- Regional skew: irrigated northwest prospered; rain-fed east lagged.
- Rising input costs trapped smallholders in debt, linked to suicides.
- Income gains uneven, widening inter-state rural disparities.
Reform Agenda
- GR 2.0 stresses crop diversification, climate-smart practices.
- Scale micro-irrigation, solar pumps, rainwater harvesting for water prudence.
- Promote organic, ZBNF, agroforestry, agrivoltaics to lift incomes sustainably.
