Explanation:

The Green Revolution was a period that began in the 1960s during which agriculture in India was converted into a modern industrial system by the adoption of technology, such as the use of high yielding variety (HYV) seeds, mechanised farm tools, irrigation facilities, pesticides and fertilizers. Mainly led by agricultural scientist M. S. Swaminathan in India, this period was part of the larger Green Revolution endeavor initiated by Norman E Borlaug, which leveraged agricultural research and technology to increase agricultural productivity in the developing world.

Under premiership of Congress leader Lal Bahadur Shastri, the Green Revolution within India commenced in 1968, leading to an increase in food grain production, especially in Punjab, Haryana, and Uttar Pradesh. Major milestones in this undertaking were the development of high-yielding varieties of wheat, and rust resistant strains of wheat. However, the long-term effects of green revolution have been analysed by environmental activists like Vandana Shiva who are of the opinion that it caused greater environmental, financial and sociological problems for the country like droughts, rural indebtedness and farmer suicides.
