What is the Green Revolution?

The Green Revolution refers to the transformation of Indian agriculture in the 1960s--1980s through the introduction of High-Yielding Variety (HYV) seeds, chemical fertilizers, pesticides, irrigation, and modern farming techniques. It was spearheaded in India by agricultural scientist M.S. Swaminathan (known as the "Father of the Indian Green Revolution") in collaboration with Norman Borlaug (the American agronomist and Nobel laureate who developed HYV wheat in Mexico). The term "Green Revolution" was coined by William Gaud of USAID in 1968.

The revolution began in earnest in 1966--67 when India imported 18,000 tons of Mexican dwarf wheat seeds (varieties like Sonora 64 and Lerma Rojo). Wheat production surged from 12 million tons (1965) to 20 million tons (1970), and India became self-sufficient in food grains by 1971. The adoption of IR8 rice (developed by IRRI, Philippines) yielded about 5 tons per hectare without fertilizer and nearly 10 tons per hectare under optimal conditions, revolutionizing rice cultivation in states like Punjab, Haryana, and western UP.

While the Green Revolution made India food-secure, it also brought negative consequences: regional concentration (primarily Punjab, Haryana, western UP), excessive use of chemical inputs degrading soil health, groundwater depletion, loss of traditional seed varieties (genetic erosion), and growing inter-regional inequality. Total grain output grew from ~80 million tons (early 1960s) to over 220 million tons by the 1990s, and stands at over 330 million tons (2023-24).

Current Status / Latest Data

  • India's total food grain production reached a record 332.2 million tons in 2023-24 (4th Advance Estimate).
  • M.S. Swaminathan passed away on September 28, 2023, at the age of 98. The Government of India posthumously awarded him the Bharat Ratna in 2024.
  • The National Mission on Sustainable Agriculture (NMSA) and Paramparagat Krishi Vikas Yojana (PKVY) aim to address the ecological damage caused by the Green Revolution by promoting organic and natural farming.
  • Punjab and Haryana face a severe groundwater crisis -- direct legacy of intensive paddy-wheat cultivation promoted during the Green Revolution.
  • A Second Green Revolution (Evergreen Revolution, as Swaminathan advocated) focusing on eastern India, millets, and sustainable practices is being pursued.

Mains: Probable Themes

  1. Achievements and limitations of the Green Revolution -- food security vs. ecological costs
  2. Regional disparity: why eastern India was left behind and the need for a Second Green Revolution
  3. Groundwater crisis in Punjab-Haryana as a direct consequence of Green Revolution cropping patterns
  4. Genetic erosion: loss of indigenous seed varieties and implications for food security
  5. Transition from Green Revolution to sustainable agriculture -- natural farming, millets, and agroecology
