1. Green Revolution In India 2. Revolution? Huh…? 3. The introduction of high-yielding varieties of seeds and the increased use of chemical fertilizers and irrigation are collectively known as the Green Revolution, which provided the increase in production needed to make India self-sufficient in food grains, thus improving agriculture in India. 4. Okay Sherlock! But who started it? 5. Why was it even needed in the first place? 6. Bengal Famine (1943) 4 million deaths  Initial believed cause – shortage of food Businessmen hoarded food 1967 – 78 : Green Revolution 7. Tell me more! 8. Continuing expansion of farming areas Double cropping Using seeds with improved genetics The green revolution was a technology package comprising material components of improved high yielding varieties of two staple cereals (rice and wheat), irrigation and improved moisture utilization, fertilizers and pesticides and associated management skills. 9. OUTCOMES 10. Record grain output of 131 million tonnes in 1978/79. Improve in yield per unit of farmland by more than 30% between 1947 and 1979. Creation of jobs for agricultural workers as well as industrial workers. 11. The Second Green Revolution 12.  Genetically modified crops  plants used in agriculture the DNA of which has been modified using genetic engineering techniques.  Examples are resistance to pests, reduction of spoilage, or improvement in nutrient profile of the crop.  Bacillus thuringiensis  Bt Cotton – resistance to pink bollworm Bt Brinjal – resistance to lepidopteron insects 13. “Man can and must prevent the tragedy of famine in the future instead of merely trying with pious regret to salvage the human wreckage of the famine, as he has so often done in the past.” - Norman Borlaug
