GREEN REVOLUTION

DEFINITION: An increase in food production, especially in

undeveloped and developing nations, through the introduction of high-yield crop varieties and application of modern agricultural techniques. The introduction of high-yielding varieties of seeds and the increased use of chemical fertilizers and irrigation are known collectively as the Green Revolution

GREEN REVOLUTION

NORMAN BORLAUGTHE FATHER OF GREEN REVOLUTION

DR. MS SWAMINATHAN FATHER OF INDIAN GREEN REVOLUTION

GREEN REVOLUTION AREAS IN INDIA

Use of High Yielding Varieties (HYV) of seeds Irrigation Use of insecticides and pesticides Consolidation of holdings Land reforms Improved rural infrastructure Supply of agricultural credit Use of (chemical) fertilizers Use of sprinklers or drip irrigation

Measures Adopted in the Green Revolution were

1 - Increase in Production / yield. 

2 - Advantage to farmers: this includes their economic situation improving, even small and marginal farmers (although they were late in joining) getting better yield, control on many insects and pests, mechanizing improved working conditions. 

3- Better land use by employing two and three crop pattern. 

4 - better scientific methods applied as per requirement of farms. 

5- New seeds have been developed with better yield and disease fighting capability. 

ADVANTAGES OF GREEN REVOLUTION

1- Degradation of land: Due to change in land use pattern and employing two and three crop rotation every year land quality has gone down and yield has suffered. 

2- Degradation of land part 2: Due to heavy chemical fertilizer inputs land has become hard and carbon material has gone down. 

3- Weeds have increased: Due to heavy crop rotation pattern we do not give rest to land nor we have time to employ proper weed removal system which has increased weeds.

DISADVANTAGE OF GREEN REVOLUTION

4- Pest infestation has gone up: Pests which we used to control by bio degradable methods have become resistant to many pesticides and now these chemical pesticides have become non effective

5- Loss of bio diversity: Due to heavy use of chemical pesticides, insecticides and fertilizers we have lost many birds and friendly insects and this is a big loss in long term. 

6- Chemicals in water: These chemicals which we have been using in our farms go down and contiminate ground water which effect our and our children health. 

7: Water table has gone down: Water table has gone down due to lack of water harvesting systems and now we have to pull water from 300 to 400 ft. depth which was 40 to 50 feet earlier. 

8: Loss of old seeds: We have started using new seeds and lost old once since new once give better yield but due to this we have lost many important geens in these seeds

Revolution means complete rotation or a great change. 'Green' refers to green crops or new grains. So, 'Green Revolution' means revolutionary change in agriculture in order to make a massive production. We have started green revolution in our country and we have been successful to a sizeable extent in it. Really, we have made a tremendous success in our wheat output in the Punjab and U.P. even there was some negative effects of green revolution
