In the mid-1960s, India was facing famine. The country had experienced severe food shortages in 1965 and 1966, was dependent on American food aid under the PL-480 programme, and was described by some development economists as a country that might never achieve food self-sufficiency. Within a decade, largely as a result of a coordinated programme of agricultural research, seed development, and government policy, India had achieved not just self-sufficiency but exportable surpluses in wheat and rice. M. S. Swaminathan, more than any other single figure, was the architect of this transformation. His work on high-yielding variety wheat and rice, his role in adapting Norman Borlaug’s Mexican wheat varieties to Indian conditions, and his later work on sustainable agriculture define a career that changed the nutritional security of a billion people.
The Pre-Green Revolution Crisis
To understand what Swaminathan achieved, it is necessary to understand what India’s food situation looked like in the early 1960s. Agricultural yields in India were among the lowest in the world. Wheat yields averaged around 800 kilograms per hectare; rice yields were similarly dismal. The country’s population was growing at approximately 2.5 percent per year. The dominant view among international development organisations was that food production could not keep pace with population growth – a view reflected in Paul Ehrlich’s 1968 book “The Population Bomb,” which predicted mass famine in the 1970s. India was importing millions of tonnes of wheat from the United States under concessional terms that made Indian agricultural policy partially hostage to American foreign policy decisions; President Lyndon Johnson’s policy of “short-tethering” food aid to India, releasing shipments month by month rather than in bulk, was experienced by the Indian government as humiliation.
The Indian government under Indira Gandhi made a strategic decision in the mid-1960s to pursue agricultural self-sufficiency as a national security priority. The decision involved importing high-yielding variety (HYV) wheat seeds developed by Norman Borlaug at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico. The varieties had shown spectacular yield increases in Mexico; the question was whether they could be adapted to Indian conditions and whether the supporting infrastructure – irrigation, fertilisers, credit, extension services – could be built quickly enough to make the adoption work at scale. Swaminathan, then director of the Indian Agricultural Research Institute in Delhi, was the central scientific figure in this adaptation effort.
The Science: Adapting HYV Seeds to Indian Conditions
Swaminathan’s scientific contribution was not simply the importation of Borlaug’s varieties. Mexican wheat varieties had been developed for Mexican growing conditions – day length, temperature range, soil type – that differed significantly from Indian conditions. Swaminathan and his team at IARI conducted systematic crosses and selection work to identify varieties that could exploit the yield potential of the Mexican dwarf wheats while being adapted to Indian photoperiod and temperature conditions. The varieties that resulted – most importantly the varieties known as Kalyan Sona and Sonalika – produced yield increases of three to four times over traditional Indian varieties when grown under irrigated conditions with adequate fertiliser inputs.
The scale at which this scientific work had to translate into practice was staggering. India needed not just new seed varieties but a distribution system capable of getting them to farmers across a country of over 500 million people; a fertiliser supply capable of supporting the high-input requirements of HYV crops; an irrigation expansion that could provide the water that HYV varieties required; extension services that could teach farmers new cultivation practices; and a procurement system that could purchase the resulting surpluses and distribute them through the public distribution system. Swaminathan worked across all of these systems, not merely as a plant scientist but as a science administrator and policy advocate. His relationship with C. Subramaniam, the agriculture minister who championed the Green Revolution approach within the Indian government, was central to translating scientific possibility into policy.
The Green Revolution was not an accident or a gift from nature. It was a deliberate, coordinated programme that required scientific excellence, administrative capacity, and political will simultaneously. Swaminathan was the figure who made those three things work together.
The Results and Their Limitations
The results of the Green Revolution in India were spectacular by any agricultural measure. Wheat production increased from 12 million tonnes in 1964-65 to 20 million tonnes in 1970-71 and continued to grow. Rice production increased similarly. India moved from food deficit to food surplus within a decade. The famines that had killed millions in Bengal in 1943 and that had threatened in the mid-1960s did not recur. The PL-480 dependence on American food aid was ended. India built substantial food grain reserves. The achievement was real and its importance for human welfare – measured in lives not lost to starvation and in the end of mass malnutrition as an immediate crisis – was immense.
But the Green Revolution’s limitations and costs were also real, and Swaminathan himself became one of their most important critics as early as the 1970s. The HYV varieties required irrigation, which meant the Green Revolution disproportionately benefited farmers in areas with reliable water supply – primarily Punjab, Haryana, and western Uttar Pradesh. Farmers in rain-fed areas of eastern India, the Deccan plateau, and much of the south benefited much less. The high-input requirements of HYV agriculture (fertiliser, pesticides, irrigation) were affordable for better-resourced farmers but difficult for marginal farmers with limited land and capital. The result was a widening of income inequality within Indian agriculture: Green Revolution prosperity concentrated in the irrigated northwest, while rain-fed farming areas lagged further behind.

The Environmental Critique and Swaminathan’s Response
The environmental costs of Green Revolution agriculture became apparent in Punjab and Haryana in the 1980s and 1990s. Intensive wheat-rice monoculture, combined with excessive groundwater extraction for irrigation, caused water table decline that has reached critical levels in parts of Punjab. Heavy pesticide use contaminated water sources and harmed human health. Soil degradation from intensive mono-cropping reduced long-term fertility. The Green Revolution had solved the problem of immediate food production by creating conditions for longer-term agricultural unsustainability in its core regions. This critique – that the Green Revolution borrowed against the future – became central to the debate about the Green Revolution’s legacy.
Swaminathan’s response to these critiques was to develop the concept of an “Evergreen Revolution” – agricultural productivity increases achieved through ecological approaches that could be sustained indefinitely rather than at the cost of resource depletion. His work at the M. S. Swaminathan Research Foundation in Chennai, founded in 1988, focused on biodiversity conservation, farmer-participatory breeding, women’s empowerment in agriculture, and the development of sustainable farming practices for marginal areas. His formulation of the concept of sustainable development in the agricultural context predates the Brundtland Commission’s more famous definition, and his work on integrating ecological sustainability with food security has been influential in international agricultural policy. His later advocacy for farmers’ welfare, including the Swaminathan Commission reports of 2004-2006 that recommended dramatic increases in agricultural support prices and rural investment, connected him to ongoing debates about farm distress in India. See our article on Operation Flood and Verghese Kurien’s dairy revolution for the parallel story of agricultural transformation in India’s milk sector.
The Swaminathan Commission and Farm Distress
The National Commission on Farmers, chaired by Swaminathan from 2004 to 2006, produced five reports that constituted the most comprehensive official analysis of the causes of farmer distress in India up to that point. The commission’s recommendations addressed the full range of factors – land policy, water management, credit access, input costs, procurement prices, extension services, and insurance – that had left a large proportion of India’s farmers in chronic economic stress despite the production achievements of the Green Revolution. The most politically prominent recommendation was for minimum support prices set at cost of production plus 50 percent profit – a formula that became the rallying demand of subsequent farmer movements and that was partially implemented under pressure from farm protests in 2021.
Swaminathan died in September 2023, aged 98. His career spanned the entire arc of modern Indian agriculture – from pre-Green Revolution famine risk to the production achievements of the HYV era to the sustainability challenges and farm distress of the twenty-first century. He ended his career arguing that the Green Revolution had been necessary but was not sufficient; that production without equity, sustainability, and farmer welfare was not a complete answer to India’s food security problem. His legacy is both the achievement of food production security – which is real and important – and the unanswered question of how to make agriculture sustainable and remunerative for the farmers who practice it. India is still working on that question.
The Evergreen Revolution Agenda
M. S. Swaminathan’s career poses a challenge for how we think about development success. The Green Revolution he led was genuinely transformative and saved millions of lives. But its environmental costs and equity limitations are also real. The lesson is not that the Green Revolution was wrong but that production success creates new problems that require new solutions – and that the institutions and political will that can deliver a Green Revolution are also necessary to manage its consequences. India has the first part of that story. The second remains incomplete.
Women in Indian Agriculture: The Missing Half
One dimension of Indian agriculture that Swaminathan repeatedly emphasised in his later work is the central role of women as agricultural labourers and household food managers, a role that is systematically invisible in agricultural statistics and policy. Women constitute over 60 percent of India’s agricultural workforce by most estimates – they perform the majority of weeding, transplanting, harvesting, and post-harvest processing work on Indian farms. And yet they are dramatically underrepresented in formal land ownership, in access to agricultural credit, in extension service contacts, and in the design of farming technologies that assume a male farmer as the primary user. The seeds, fertilisers, and irrigation infrastructure of the Green Revolution were designed and distributed on the assumption that the decision-making farmer was male.
The M. S. Swaminathan Research Foundation’s work in this area – particularly its focus on village food and nutrition security, on women’s kitchen garden programmes, and on women’s farmer groups – represented an attempt to correct this invisibility. MSSRF programmes specifically targeted women farmers for training, technology access, and organisational support. The foundation’s work in coastal communities after the 2004 tsunami, and its long-term engagement with communities in Tamil Nadu, Odisha, and Puducherry, consistently centred women’s agency and knowledge as resources for food security rather than as recipients of development benefits. This emphasis, which drew on the development economics research of Amartya Sen (with whom Swaminathan collaborated) on entitlements and capabilities, shaped a more nuanced understanding of agricultural development than the Green Revolution’s production-focused framework had allowed.
The Next Green Revolution: What India Needs Now
The phrase “second Green Revolution” or “Evergreen Revolution” has become something of a cliche in Indian agricultural policy discourse, but the underlying challenge it references is real and urgent. India’s agricultural productivity remains substantially below its potential in most crops and most regions. Rain-fed agriculture – covering roughly 60 percent of India’s cultivated area – has seen much less improvement than irrigated agriculture. Pulses and oilseeds, which are critical for nutritional security and import substitution, lag behind the yield gains achieved in wheat and rice. Climate change is introducing new stresses – irregular monsoons, increased temperature extremes, new pest and disease patterns – that the varieties and practices of the first Green Revolution are not adapted to handle.
What the next agricultural transformation in India requires is different from what the first one required. In 1965, the binding constraints were seed quality and production technology. In 2026, the constraints are more varied: water management in a context of falling water tables and irregular rainfall; soil health degraded by decades of intensive chemical input; market access for smallholders who cannot afford to wait for government procurement and cannot negotiate with private traders; climate adaptation that maintains productivity under new and changing conditions. These challenges require not a single technological solution analogous to HYV seeds but a portfolio of interventions tailored to different cropping systems, regions, and farmer types. Swaminathan’s Evergreen Revolution concept was a response to exactly this complexity. Whether India’s agricultural policy establishment will develop the institutional capacity and sustained political commitment to address it comprehensively remains the central question of Indian food security policy. The connection between agricultural transformation and rural employment is also explored in our analysis of Operation Flood and Verghese Kurien’s dairy cooperative model.
