Green Revolution — Core Concepts
Core Concepts
The Green Revolution (1960s-1980s) was India's agricultural transformation that achieved food self-sufficiency through High Yielding Variety seeds, modern irrigation, chemical fertilizers, and pesticides.
Led by Norman Borlaug globally and M.S. Swaminathan in India, it primarily benefited Punjab, Haryana, and western UP, transforming them into India's granary. Wheat production increased from 12.3 to 55.
1 million tonnes (1965-91), while rice production rose from 30.6 to 74.3 million tonnes. Key technologies included semi-dwarf wheat varieties (Kalyan Sona, Sonalika), miracle rice (IR-8), assured irrigation through tube wells, and chemical inputs.
The revolution eliminated famines and food imports but created environmental problems (soil degradation, groundwater depletion), regional disparities, and social inequalities. It established the foundation for modern Indian agriculture and influenced current policies on food security, agricultural subsidies, and sustainable farming.
The revolution demonstrates both the potential and limitations of technology-driven agricultural development.
Often confused with
Side-by-side differences the UPSC paper likes to test.
| Aspect | Green Revolution | Traditional Agriculture |
|---|---|---|
| Seeds | High Yielding Variety (HYV) seeds - scientifically developed, semi-dwarf, fertilizer responsive | Indigenous varieties - locally adapted, tall plants, low fertilizer response |
| Inputs | Chemical fertilizers, pesticides, assured irrigation, mechanization | Organic manures, natural pest control, monsoon-dependent, manual labor |
| Productivity | High productivity - wheat 4000+ kg/ha, rice 3000+ kg/ha | Low productivity - wheat 800-1200 kg/ha, rice 1000-1500 kg/ha |
| Cropping Pattern | Intensive cropping, monoculture, 2-3 crops per year | Mixed cropping, crop rotation, single crop per year |
| Environmental Impact | Soil degradation, groundwater depletion, chemical pollution | Sustainable practices, soil health maintenance, biodiversity conservation |
The Green Revolution represented a fundamental shift from traditional, sustainable but low-productivity agriculture to modern, high-input, high-output farming systems. While it achieved food security, it came at the cost of environmental sustainability and increased input dependency, leading to current discussions about sustainable intensification and natural farming approaches.
Why it is tested: Frequently tested in questions comparing traditional and modern agricultural practices, environmental impact assessment, and sustainable development approaches in agriculture.
| Aspect | Green Revolution | Gene Revolution |
|---|---|---|
| Technology Base | Conventional plant breeding, chemical inputs, mechanical technology | Genetic engineering, biotechnology, molecular breeding techniques |
| Time Period | 1960s-1980s, mature technology with established results | 1990s onwards, emerging technology with ongoing development |
| Crop Focus | Primarily wheat and rice, food grain crops | Diverse crops including cotton, vegetables, fruits, specialty crops |
| Approach | Productivity enhancement through external inputs and improved varieties | Trait-specific improvement through genetic modification |
| Acceptance | Widely accepted, government-supported, farmer-adopted | Controversial, regulatory challenges, mixed farmer acceptance |
While the Green Revolution used conventional breeding and chemical inputs to increase productivity, the Gene Revolution employs genetic engineering for specific trait development. The Green Revolution achieved broad-based food security, while the Gene Revolution targets specific agricultural challenges like pest resistance and climate adaptation, though with greater controversy and regulatory complexity.
Why it is tested: Important for questions on agricultural technology evolution, biotechnology policy, and comparative analysis of different approaches to agricultural development.
