PowerPoint Presentation On Green Revolution

PPT On The Green Revolution


1. The Green Revolution.

2. Why? When?
The green revolution applies to many third world countries, but the most successful experiment was the one in India.

Here the Bengal Famine, (the world's worst recorded food disaster) happened in 1943. An estimated four million people died of hunger that year alone in eastern India.

It was therefore natural that food security was a paramount item on free India's agenda. This awareness led to the Green Revolution in India. However, the term "Green Revolution" is applied to the period from 1967 to 1978. Between 1947 and 1967, efforts at achieving food self-sufficiency were not entirely successful.

Efforts until 1967 largely concentrated on expanding the farming areas. But starvation deaths were still being reported. In a perfect case of Malthusian economics, population was growing at a much faster rate than food production. This called for drastic action to increase yield. The action came in the form of the Green Revolution.

3. What was the Green Revolution in India?

There were three basic elements in the method of the Green Revolution:

1) Continued expansion of farming areas.

2) Double-cropping existing farmland.

3) Using seeds with improved genetics.

4. Continued expansion of farming areas.
The area of land under cultivation was being increased right from 1947, but this was not enough in meeting with the rising demand.

Other methods were required to increase resources. Yet, the expansion of cultivable land also had to continue.

So, the Green revolution continued with this quantitative expansion of farmlands, even though it was not the most striking feature of the revolution.

5. Double-cropping existing farmland
Double-cropping was a primary feature of the Green Revolution.
Instead of one crop season per year, the decision was made to have two crop seasons per year. The one-season-per-year practice was based on the fact that there is only natural monsoon per year.

So, there had to be two "monsoons" per year. One would be the natural monsoon and the other an artificial 'monsoon’.
The artificial monsoons were created by huge irrigation facilities. Dams were built to arrest large volumes of natural monsoon water which were earlier being wasted. Simple irrigation techniques were also adopted.

6. Using seeds with improved genetics
This was the scientific aspect of the Green Revolution. The Indian Council for Agricultural Research was re-organized in 1965 and then again in 1973.

It developed new strains of high yield value (HYV) seeds, mainly wheat and rice but also millet and corn. The most noteworthy HYV seed was the K68 variety for wheat.

The credit for developing this strain goes to Dr. M.P. Singh who is also regarded as the hero of India's Green revolution.

7. Advantages:
1) The Green Revolution resulted in a record grain output of 131 million tons in 1978-79. This established India as one of the world's biggest agricultural producers. No other country in the world which attempted the Green Revolution recorded such level of success. India also became an exporter of food grains around that time.

2) Yield per unit of farmland improved by more than 30 per cent between 1947 and 1979 when the Green Revolution was considered to have delivered its goods.

3) The crop area under HYV varieties grew from seven per cent to 22 per cent of the total cultivated area during the 10 years of the Green Revolution. More than 70 per cent of the wheat crop area, 35 per cent of the rice crop area and 20 per cent of the millet and corn crop area, used the HYV seeds.

4) Crop areas under high-yield varieties needed more water, more fertilizer, more pesticides, fungicides and other chemicals. This spurred the growth of the local manufacturing sector. Such industrial growth created new jobs and contributed to the country's GDP.

5) The increase in irrigation created need for new dams to harness monsoon water. The water stored was used to create hydro-electric power. This in turn boosted industrial growth, created jobs and improved the quality of life of the people in villages.

6) India paid back all loans it had taken from the World Bank and its affiliates for the purpose of the Green Revolution. This improved India's creditworthiness in the eyes of the lending agencies.

7) Some developed countries, especially Canada, which were facing a shortage in agricultural labour, were so impressed by the results of India's Green Revolution that they asked the Indian government to supply them with farmers experienced in the methods of the Green Revolution. Many farmers from India were thus sent to Canada where they settled. These people remitted part of their incomes to their relatives in India. This not only helped the relatives but also added to India's foreign exchange earnings.

8. Disadvantages:
1) Even today, India's agricultural output sometimes falls short of demand. The Green Revolution, howsoever impressive, has thus not succeeded in making India totally and permanently self-sufficient in food. In 1979 and 1987, India faced severe drought conditions due to poor monsoon; this raised questions about the whether the Green Revolution was really a long-term achievement. In 1998, India had to import onions, due to a lack of crops.

2) India has failed to extend the concept of high-yield value seeds to all crops or all regions. In terms of crops, it remains largely confined to food grains only, not to all kinds of agricultural produce. In regional terms, only Punjab and Haryana states showed the best results of the Green Revolution. The eastern plains of the River Ganges in West Bengal state also showed reasonably good results, but others were less impressive in other parts of India.

9. Conclusion
Nothing like the Bengal Famine can happen in India again. But even today, there are places like Kalahandi where famine-like conditions have been existing for many years and where some starvation deaths have also been reported. This is due to some reasons other than availability of food in India, but the very fact that some people are still starving in India (whatever the reason may be), brings into question whether the Green Revolution has failed in its social objectives.

So, overall I feel that the Green revolution, in this case in India, has not been 100% successful, even though it has been a resounding success in terms of agricultural production.

10. Thanks
