Why is it in the News?

Recently, Prime Minister Modi announced that the agriculture scientist M S Swaminathan will be honoured with the Bharat Ratna.

Who was MS Swaminathan?

• Monkomb Sambasivan Swaminathan (MS Swaminathan) was born on August 7, 1925, in Kumbakonam, Madras Presidency (now Tamil Nadu).
• He was an agronomist, agricultural scientist, plant geneticist, administrator, and humanitarian.
• He was known as the ‘father of the Green Revolution’ in India.
• Swaminathan began his career in 1949 researching the genetics of potatoes, wheat, rice, and jute.
  • He played a crucial role in developing high-yielding varieties of paddy that helped ensure India’s low-income farmers produced more yield.
• Also known as the ‘father of economic ecology’ by the United Nations Environment Programme, he worked with agriculture ministers including C Subramaniam and Jagjivan Ram during the 1960s and 70s for the success of the ‘Green Revolution’ in India.
  • An initiative that paved the way for an exponential rise in the productivity of wheat and rice through the adaptation of chemical-biological technology.
• Career: Swaminathan also held administration positions in various agricultural research laboratories.
  • He served as the director general of the Indian Council of Agricultural Research and International Rice Research Institute.
  • He also worked as the principal secretary of the Ministry of Agriculture in 1979.
  • Later, he also served as the President of the International Union of the Conservation of Nature and Natural Resources.
  • In 2004, Swaminathan was appointed as chairman of the National Commission on Farmers.
• Awards and Recognition: He was awarded with the Ramon Magsaysay Award in 1971 and the Albert Einstein World Science Award in 1986.
  • He was awarded the first World Food Prize in 1987, following which he set up the MS Swaminathan Research Foundation in Chennai.
  • Swaminathan has also been conferred with the Padma Shri, Padma Bhushan, and Padma Vibhushan - the three most prestigious awards.
  • Apart from these, he was also given the H K Firodia Award, the Lal Bahadur Shastri National Award, and the Indira Gandhi Prize.
• Swaminathan also contributed to various agricultural and environmental initiatives globally.
  • He was named one of the 20 most influential Asians of the 20th century by Time magazine.
• He also served as a Member of Parliament in the Rajya Sabha from 2007 to 2013.
• MS Swaminathan passed away in September 2023 at the age of 98.
• His decision to focus on ensuring India's food security led him to become a key figure in the Green Revolution of the 1960s, which transformed India from a food-deficient nation to one of the world's leading agricultural producers.
  • His collaboration with Nobel laureate Norman Borlaug introduced high-yielding varieties of wheat and rice, saving millions from starvation.
• Dr Swaminathan's transformative influence on Indian agriculture began to emerge when he championed the introduction of high-yielding crop varieties.
  • His visionary approach was instrumental in pioneering the Green Revolution in India when the country was still grappling with poverty and a lack of social security.
• The impact of Dr. Swaminathan's efforts was nothing short of revolutionary.
• India's food production skyrocketed, and the nation moved from a state of food scarcity to food self-sufficiency.
• His work not only averted potential famines but also elevated the economic conditions of countless farming communities.

How MS Swaminathan Contributed to the Green Revolution?

• MS Swaminathan was greatly influenced by Mahatma Gandhi's teachings of selfless service to the poor and the nation.
• He was very much influenced by the 1943 Bengal famine, which killed up to three million people and realised the need to improve agriculture and food security in India.
• After Swaminathan’s work on rice, he and other scientists worked on doing the same to enhance productivity for the wheat crop.
• India had to get Norin dwarfing genes from Norman Borlaug in Mexico to enhance the productivity and adaptability of its wheat crops.
  • These genes, known for their ability to produce shorter wheat plants, were instrumental in the Green Revolution, as they helped increase yield potential and improve resistance to lodging (falling over) in wheat plants.
  • By acquiring these genes, India aimed to replicate the success of the Green Revolution and address food security challenges by boosting wheat production.
• Norman Borlaug was an American scientist who was working on developing more productive crop varieties.
  • It led to him winning the Nobel Peace Prize in 1970 for his work in developing High Yielding Varieties (HYVs) of wheat.
• Many researchers and scientists were involved in this work but there isn’t any doubt that the basic strategic vision underpinning the Green Revolution in India, introducing a new genetic strain or ‘plant type’ responsive to increased fertiliser and water application came from MS Swaminathan.
• The problem with the traditional wheat and rice varieties was that they were tall and slender.
  • These ‘lodged’ – fell flat on the ground — when they grew and their heads were heavy with well-filled grains produced in response to high fertiliser doses.
  • Through Swaminathan’s research on rice, a reduction in plant height was sought to make them less lodging-prone but this was not easy to do.
• His strategy of developing semi-dwarf wheat varieties using mutagenesis exposing plants to chemicals or radiation to introduce desirable modifications in their DNA did not, however, work.
  • The lowering of plant heights led to a simultaneous reduction in the size of the grain-bearing panicles or earheads.
• The search for an ideal variety led him to contact American scientist Orville Vogel.
  • He played a role in developing a ‘dwarf wheat’ called Gaines, which had a high yield.
  • It contained dwarfing genes from a dwarf wheat called the Norin-10.
• Vogel agreed but was unsure of the wheat’s potential in the Indian climate and thus advised Swaminathan to approach Norman Borlaug, who had incorporated the same dwarfing genes through Vogel’s lines into his spring wheat varieties in Mexico that were better suited for India.
  • Borlaug also later visited India, after Swaminathan proposed so to the Indian Agricultural Research Institute, allowing for the wheat breeding programme to commence.
• In 1963, they began a serious effort to breed dwarf wheat and within five years, this initiative led to what became known as the "Wheat Revolution."
  • Indira Gandhi, the then Prime Minister of India, released a special stamp to mark the achievement.

The Side Effects of the Green Revolution:

• Despite its landmark role in achieving food sufficient in India, the Green Revolution has been criticised on multiple counts, such as:
  • Benefiting the already prosperous farmers as it was introduced in states with higher productivity.
• Swaminathan recognised such issues as early as January 1968, addressing the Indian Science Congress at Varanasi.
• He highlighted concerns about the rapid spread of a few high-yielding crop varieties replacing diverse local ones, leading to potential problems like soil degradation, desertification, excessive pesticide use, and unsustainable groundwater extraction.
  • Unfortunately, many of these concerns have materialised today.
• He also lent his support to farmers as the head of the National Commission on Farmers from 2004-06, he recommended that the Minimum Support Price at which farmers sell their crops to the government should be at least 50 per cent more than the weighted average cost of production.
• For his contributions, Swaminathan was awarded the first World Food Prize Laureate in 1987, for “developing and spearheading the introduction of high-yielding wheat and rice varieties into India during the 1960s when that country faced the prospect of widespread famine.
• Wheat production doubled in just a few years, making the country self-sufficient and saving millions from extreme food deprivation.
