3. Learning Objectives
To understand how the Green Revolution increased food supply in the Punjab, India.
To be able to critically evaluate the pros and cons of the Green Revolution.

4. What is the Green Revolution?
A package of modern, western-style farming techniques used to transform agriculture in developing countries.
It’s aims:
A technological fix to increase yields of staple foods, feed the world, and prove Malthus wrong.
Ending subsistence farming and replacing it with commercial farming.
Increasing self-sufficiency of LEDCs.
The answer to global food shortages

5. Activity: How did the Green Revolution occur?

6. The Green Revolution in India
Annotate/highlight your information sheet as we go through the slides.
Background:
In 1943, the worst recorded food disaster occurred in India, known as the Bengal famine.
Four million people died of starvation in eastern India alone, largely due to a shortfall in food production.

7. The Green Revolution in India
Background continued:
Consequently, food security became one of the main items on ‘free’ India’s agenda.
By 1964 many farmers in India were short of food, lacked a balanced diet and had an extremely low standard of living.
The government had limited resources and decided to try to improve farm technology to overcome the crisis.
India became independent in 1947

8. Case study focus: Punjab, India
Label Punjab on your map and add notes to it.
The Punjab is a state in north-western India, straddling the border between India and Pakistan.
It is known as the ‘land of the five rivers’ and thought to be one of the most fertile places in the world.

Continued expansion of farming areas
The area of land under cultivation had been increasing since 1947, but it was not enough in meeting rising demand.

10. Strategies to increase food supply in Punjab
Double-cropping existing farmland
Instead of one crop season per year, there would be two crop seasons per year.
Artificial ‘monsoon’ in the form of huge irrigation projects.
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.'

11. Strategies to increase food supply in Punjab
Using seeds with superior genetics
18,000 tonne of Mexican HYV wheat seeds were imported.
The Indian Council for Agricultural Research developed new strains of HYV seeds, mainly wheat and rice, but also millet and corn. K68 variety of wheat is most noteworthy.

Technologies were developed
Large amounts of fertiliser were imported.
Tractors were introduced to replace water buffalo.
