Advantages of green revolution
The great increase in the production of food – grain crops
Crops serve as food. Our food crops are of four types: food grains, vegetables, fruits, and non – food grains (like cotton). In our country, about 75 per cent of the total cultivated area is used for growing food – grains such as wheat, rice, jowar, bajra, maize, pulses and oilseeds. Most of our food, however, comes from wheat, rice and pluses. Our farmers have been making efforts to grow more and more food. Due to these efforts, the average production of most of the crops has doubled during the last 30 years. But the production of wheat crop has tripled during the last 30 years. This large increase in crop yields leading to record food production started in out country from 1960 on wards and marked a turning point in Indian agriculture which has led to green revolution in our country.
The great increase in the production of food – grain crops (especially the wheat crop) in our country during the last 30 years is called green revolution. This is became a sort of revolution has taken place in Indian agriculture leading to enormous food grain production. The revolution is called green because it has led to unprecedented greenery of crops every where. The period from 1960 to 1980 is also called golden era for the record food- grain production. It is because of the green revolution that our country has become self sufficient in food production and even buffer stocks of food-grains have been created for use in the times of natural calamities like drought (sookha), and floods, when the food production is reduced.
The green revolution
Advantages of green revolution
The green revolution has made our country self – sufficient in wheat grain production. Even the buffer stocks of food – grains have been created for use in emergencies like drought and floods. In fact, the green revolution has wiped out hunger and starvation from the life of Indians. The green revolution has improved the economic condition of farmers. Because of the increased grain production, the farmers earn more money and lead a better life. By creating a great demand for agricultural inputs and implements, the green revolution has made agriculture an industry which gives employment to a large section of our people. This is because now agriculture needs the help of many other industries which produce agriculture linked industries give employment to a large number of people.
The green revolution has made the soil more dependent on fertilizers
ILL – effects of green revolution
Though green revolution has provided us enough food eat, but at the same time it has created some ill – effects in the environment around us.
The green revolution has made the soil more dependent on fertilizers. This is because the high – yielding varieties of crops suck a lot more of plant nutrients from the soil. The use of excessive fertilizers as required by the green revolution alters the soil chemistry (making the soil more acidic or alkaline), and also pollutes water resources like rivers and lakes, etc., making it unfit for human or animal consumption.
The green revolution has made the crops more dependent on weedicides and pesticides for new crop varieties, decreases the soil fertility and affects human and animal health. The high – yielding varieties of crops cultivated in green revolution demand more water. To provide more water to such crops, the existing natural sources of water are altered artificially. And this creates an imbalance in nature.
