Answer:
GREEN REVOLUTION:-
The Green Revolution, or the Third Agricultural Revolution, is the set of research technology transfer initiatives occurring between 1950 and the late 1960s, that increased agricultural production worldwide, beginning most markedly in the late 1960s.[1] The initiatives resulted in the adoption of new technologies, including High-Yielding Varieties (HYVs) of cereals, especially dwarf wheat and rice. It was associated with chemical fertilizers, agrochemicals, and controlled water-supply (usually involving irrigation) and newer methods of cultivation, including mechanization. All of these together were seen as a 'package of practices' to supersede 'traditional' technology and to be adopted as a whole.[2]
Both the Ford Foundation and the Rockefeller Foundation were heavily involved in its initial development in Mexico.[3][4] One key leader was Norman Borlaug, the "Father of the Green Revolution", who received the Nobel Peace Prize in 1970. He is credited with saving over a billion people from starvation. The basic approach was the development of high-yielding varieties of cereal grains, expansion of irrigation infrastructure, modernization of management techniques, distribution of hybridized seeds, synthetic fertilizers, and pesticides to farmers.

It is not a violent Red Revolution like that of the Soviets, nor is it a White Revolution like that of the Shah of Iran. I call it the Green Revolution."[
Merits of the Green Revolution
Green Revolution introduces a number of modern farming methods in India.
(i) Higher yield due to the use of HYV seeds.
(ii) Machines like harvesters, tractors and threshers have made ploughing and harvesting faster and easier.
(iii) Higher yield enabled farmers to sell the surplus food in the market and earn more.
(iv) Pesticides and insecticides are able to protect the crops from pests and insects.
(v) A good irrigation system is able to enhance crop production.
Demerits of the Green Revolution
(i) Loss of soil fertility due to increased use of chemical fertilisers.
(ii) Continuous use of groundwater for tubewell irrigation has reduced the water table below the ground.
(iii) The chemical fertilisers, easily soluble in water, can dissolve in the groundwater and pollute it.
(iv) They can kill bacteria and other micro-organisms helpful for the soil.
(v) Excessive use of fertilisers can also make the soil alkaline and unfit for cultivation.
