The Green Revolution refers to a period of major technological advancements in agriculture that began in the mid-20th century.

Its goal was to increase global food production to combat widespread hunger and famine, particularly in the developing world.

The movement was spearheaded by the American agronomist Norman Borlaug, who is often called the 'Father of the Green Revolution.'

A key component was the development of high-yield varieties (HYVs) of staple crops, especially wheat and rice.

These new varieties were more responsive to fertilizers and more resistant to disease.

The Green Revolution also involved the widespread adoption of a package of modern agricultural techniques.

This package included the use of chemical fertilizers, pesticides, and new irrigation methods.

The Green Revolution led to a dramatic increase in agricultural yields in many countries, particularly in Asia and Latin America.

It is credited with saving over a billion people from starvation.

However, it has also been criticized for its environmental impact, its reliance on chemical inputs, and for benefiting larger, wealthier farmers more than smallholders.
