Context: Why India Needed a Green Revolution
Bengal famine 1943 → PL-480 humiliation → C Subramaniam → Norman Borlaug → MS Swaminathan
🌾 “Ship to Mouth” — India’s Food Crisis Before the Green Revolution
Before 1966, India had earned a shameful nickname: a “ship to mouth” economy. Grain ships from America would arrive at Indian ports under the PL-480 deal, and the wheat would go directly from the ships into the mouths of Indians — that’s how close to famine India lived. In 1967, US President Lyndon B. Johnson held back a grain ship mid-voyage to pressure India on the Vietnam War. This food insecurity — this dependence on another country’s goodwill to not starve — was the most urgent national humiliation driving the Green Revolution.
1943 — Bengal Famine
Colonial Bengal famine kills 2–3 million. Food insecurity seared into India’s national memory as an existential threat. MS Swaminathan witnesses the famine as a teenager — shapes his lifelong commitment to food security.
1954 — PL-480 Agreement (USA)
India signs Public Law 480 with the US — receives food aid under “Government Agricultural Trade Development Assistance.” Ships land with American grain directly feeding Indian population — “ship-to-mouth” dependence. India pays in rupees, USA spends on India programs.
1961–65 — Food Production Stagnates
Foodgrain production growth halves from ~3% (1955-60) to just 1.5% per year. India depends on rain-fed agriculture — monsoon failures cause repeated famines and shortfalls. Population growing faster than food production.
1965 — Turning Point: C Subramaniam’s Two-Point Formula
C Subramaniam, Food and Agriculture Minister in PM Lal Bahadur Shastri’s Cabinet, proposes a two-point formula: (1) Procurement of new High Yielding Variety seeds from abroad; (2) Guarantee of procurement prices to incentivise farmers. This political commitment unlocks the Green Revolution.
1966 — 18,000 Tonnes of Mexican Wheat Seeds
MS Swaminathan, in collaboration with Norman Borlaug, persuades the Indian government to import 18,000 tonnes of semi-dwarf Mexican wheat seeds (Sonalika and Kalyan Sona varieties). Unprecedented agricultural procurement. Distributed across Punjab and Haryana — and this single decision transforms India’s food landscape.
1967–78 — The Green Revolution Decade
Green Revolution takes root. Wheat production surges from 12 million tonnes (1964) to 20 million tonnes (1970) — within just 6 years. By 1971, India declares itself self-sufficient in foodgrains. The PL-480 humiliation is over.
Key People & Terms — Learn First
- Norman Borlaug: American agronomist | Father of the Green Revolution (World) | Developed semi-dwarf high-yielding wheat varieties at CIMMYT, Mexico | Nobel Peace Prize 1970 | His Mexican wheat seeds were the catalyst for India’s Green Revolution
- MS Swaminathan: Father of the Green Revolution (India) | Geneticist | Former Director General of ICAR | Collaborated with Borlaug | Convinced Indian government to procure Mexican seeds 1966 | Later coined “Evergreen Revolution” (1990) | Born August 7, 1925, Kumbakonam, TN | Died September 28, 2023, Chennai, age 98
- C Subramaniam: Food and Agriculture Minister in Shastri’s Cabinet (1964–66) | Architect of the political support for Green Revolution | His two-point formula (HYV procurement + guaranteed prices) was the policy backbone | Called “the man who got India out of PL-480 trap”
- William Gaud: USAID Director | First person to use the term “Green Revolution” in a 1968 speech — describing the dramatic agricultural transformation in Asia
- PL-480: Public Law 480 (USA, 1954) — food aid scheme | India depended on it for US wheat imports | Its humiliation was India’s greatest motivation to achieve food self-sufficiency

India’s First Green Revolution — 1965–1978
4 pillars: HYV Seeds · Chemical Fertilizers · Mechanization · Irrigation
1. High Yielding Variety (HYV) Seeds
The core technology of the Green Revolution
What: Semi-dwarf varieties of wheat and rice that produce 2–3x more than traditional varieties per hectare. Wheat varieties: Sonalika, Kalyan Sona (from Mexican semi-dwarf wheats developed by Borlaug — shorter stem, more grain, less lodging). Rice: IR-8 “Miracle Rice” (developed at IRRI, Philippines — yields 5–10x traditional varieties). 5 crops targeted: Wheat, Rice, Jowar, Maize, Bajra. Why dwarf/semi-dwarf? Shorter stems don’t fall over (lodge) under heavy grain loads when fertilized — traditional tall varieties couldn’t bear the weight of extra grain. Trade-off: HYV seeds require MORE water, MORE fertilizer, MORE pest protection — they are high-input, high-output.
2. Chemical Fertilizers & Pesticides
NPK revolution — urea, DAP, pesticides
Fertilizers: Nitrogen (urea), Phosphorus (DAP — Di-ammonium phosphate), Potassium (MOP — Muriate of Potash). HYV seeds require heavy NPK inputs — traditional varieties could survive with farmyard manure alone. Fertilizer consumption grew from 0.07 MT (1951-52) to 6.9 MT (1980-81). Pesticides: Organochlorine (DDT, BHC), organophosphate pesticides used massively. Problem: Chemical fertilizer overuse leads to soil acidification, nutrient imbalance (NPK-only — ignores micronutrients), groundwater nitrate pollution. Pesticide overuse: bioaccumulation, cancer risk (Punjab — “cancer train”), pest resistance buildup.
3. Mechanization of Agriculture
Tractors, threshers, harvesters — replacing bullocks
What: Replacement of traditional bullock-powered agriculture with machinery. Key machinery: Tractors (ploughing), power tillers, combine harvesters (cutting+threshing simultaneously), seed drills (uniform sowing), tube well pump sets (electric/diesel). Impact: Increased timeliness and precision of operations, reduced labour costs, enabled double-cropping (second crop planted immediately after first harvest — only possible with machine speed). Problem: Large capital investment → benefited large farmers most | Reduced agricultural employment → displaced landless labourers | Over-mechanization uses fossil fuels → contributes to air pollution.
4. Expansion of Irrigation
From “gamble on monsoon” to assured water supply
Status before GR: Only ~30 million hectares irrigated (1960). Rain-fed agriculture = gamble on monsoon. What expanded: Tube wells (groundwater extraction — massive expansion in Punjab, Haryana, UP), canals (extended existing canal networks), small dams, check dams, lift irrigation. Result: HYV seeds need reliable water (unlike drought-tolerant traditional varieties) → irrigation expansion was essential for Green Revolution. Punjab’s tragedy: From 3.5 lakh tubewells (1980) to 14+ lakh (2021) — groundwater table dropping 30–50 cm/year in many blocks. 300+ blocks officially “overexploited” — irreversible aquifer depletion in progress.

Achievements of the First Green Revolution
From famine to food exporter · 82 MT → 330 MT · Self-sufficiency achieved
✅ Quantitative Achievements — Data for UPSC
- Foodgrain production surge: 82 million tonnes (1960-61) → 131 MT (1978-79) → 176 MT (late 1990s) → ~330 MT (2023-24) — a record. Production grew over 4× in 6 decades while cultivated area barely changed.
- Wheat production: 12 MT (1964) → 20 MT (1970) → self-sufficiency declared by 1971 | Wheat yield rose from ~850 kg/ha (1960s) to ~3,200 kg/ha today
- Rice: IR-8 “miracle rice” (developed IRRI) raised rice yields | Rice yields: ~1,013 kg/ha (early 1960s) → 2,500+ kg/ha (late 2010s)
- End of PL-480 dependence: India stopped importing wheat under PL-480 by early 1970s | From “ship to mouth” → food surplus nation
- Net exporter: India became a net exporter — rice exports reached 18.5 MT in FY2020-21 (record high) | wheat exports 2.1 MT (highest in 6 years)
- India’s global agricultural rankings: 1st in milk production | 1st in pulses | 1st in jute | 2nd in rice | 2nd in wheat | 2nd in vegetables | 2nd in fruits | 2nd in groundnut | Major fisheries producer
- Per capita food availability: Rose from ~140 kg/year (early 1950s) to ~188 kg/year (2021-22)
- Poverty alleviation: Rising agricultural incomes lifted millions out of poverty | Punjab became India’s richest state per capita by the 1980s
- Agricultural growth 2015-2024: India’s agriculture grew at 4.5% per year — highest in history (demand growing at only 2.5%/year)

The Dark Side of the First Green Revolution
Regional inequality · Environmental damage · Social disparities · “Cancer train” of Punjab
❌ Negative Impacts — The Price of Food Security
- 1. Crop narrow focus — wheat and rice ONLY: Green Revolution benefits were overwhelmingly concentrated in wheat and rice. Pulses (dal), oilseeds (groundnut, mustard), millets (bajra, jowar, ragi), vegetables — all largely IGNORED. India still faces a dal crisis — it is one of the largest pulse importers despite being #1 producer. Nutritional diversity lost as wheat-rice monoculture replaced diverse traditional cropping systems.
- 2. Regional concentration — only Punjab, Haryana, western UP: GR benefits were almost entirely limited to irrigated north-western India. Eastern India (Bengal, Bihar, Odisha, Assam) — which has more farmers and more poverty — was LEFT OUT. This created massive regional inequality. Punjab and Haryana prospered; Bihar and Odisha stagnated. This is precisely why BGREI (Bringing Green Revolution to Eastern India) was launched in 2010.
- 3. Groundwater depletion — Punjab’s slow death: Intensive paddy cultivation requires enormous water. Punjab’s water table is falling at 30–50 cm per year in many districts. Over 300 blocks are officially “overexploited” — meaning more water extracted than naturally replenished. At current rates, key aquifers may be exhausted within decades — an irreversible ecological catastrophe.
- 4. Soil degradation: Continuous wheat-rice monoculture with only NPK fertilizers: soil organic carbon depleted, micronutrient deficiencies (zinc, boron, sulfur) widespread, soil pH altered (acidification in some areas, alkalinisation in others), soil compaction from heavy machinery. Punjab’s soil productivity is declining despite more inputs — “chemical treadmill.”
- 5. Punjab’s “Cancer Capital” — chemical poisoning: Pesticide residues from decades of heavy use have contaminated water and food in Punjab. The Bhatinda-Amritsar train is called the “Cancer Express” or “Cancer Train” — because so many cancer patients travel on it to Bikaner for treatment. Cancer incidence in Malwa region of Punjab is significantly higher than national average — linked to pesticide and heavy metal contamination of groundwater.
- 6. Eutrophication: Nitrogen-rich runoff from chemical fertilizers into water bodies → explosive algal growth → oxygen depletion → fish and aquatic life death. Punjab’s ponds, lakes, and rivers severely affected.
- 7. Rich farmer bias — ignored small and marginal farmers: HYV technology requires capital: seeds, fertilizers, pesticides, machinery, irrigation. Small and marginal farmers (who hold <2 hectares — ~85% of India’s farmers) largely could NOT afford to participate. Green Revolution widened intra-rural inequality — rich farmers got richer, small farmers were left behind or became labourers.
- 8. Neglect of eastern India: States like Bihar, Odisha, West Bengal, Jharkhand — which have rich water resources and large agricultural populations — received almost none of the Green Revolution’s benefits. Their soil, their climate, their farmers were not targeted. This perpetuated poverty and food insecurity in these states despite national self-sufficiency.
- 9. Stubble burning: Mechanized combine harvesters leave large amounts of rice and wheat stubble. Punjab and Haryana farmers burn it (to quickly prepare for the next crop) → massive air pollution in Delhi-NCR every October-November. A direct consequence of Green Revolution’s mechanization and cropping pattern.
- 10. Biodiversity loss: Traditional diverse crop varieties replaced by a few HYV monocultures. India lost thousands of indigenous rice and wheat varieties — a loss of genetic heritage that future generations cannot recover.

Second Green Revolution — The Evergreen Revolution
MS Swaminathan’s vision — “Productivity in perpetuity without ecological and social harm”
🌿 Evergreen Revolution = Green Revolution 2.0 with a Conscience
The First Green Revolution was like sprinting — fast results, but at the cost of long-term health (ecological degradation). The Evergreen Revolution is about running a marathon sustainably — maintaining momentum without exhausting the runner (the land, the water, the farmer). MS Swaminathan defined it as: “productivity improvement in perpetuity without ecological and social harm.” It’s not just about more food — it’s about better food, for more people, from healthier farms, with happier farmers, forever.
Why We Need a Second Green Revolution
The Need — 7 Pressing Reasons
- 1. Stagnation in productivity: Yield growth has plateaued for wheat and rice in Punjab/Haryana — we cannot keep extracting more from the same degraded land with the same methods. India’s paddy yields (~2,800 kg/ha in 2022-23) are far below China’s (~6,500 kg/ha) — enormous yield gap to close sustainably.
- 2. Climate change: Agriculture is a “gamble on monsoon.” Climate change brings extreme heat, erratic rainfall, new pests, floods, droughts — all threatening yields of the crops on which the 1st GR was built. New climate-resilient varieties are urgently needed.
- 3. Declining soil and water health: Soil degradation, groundwater depletion, chemical pollution — the ecological foundations of the 1st GR are collapsing. A new approach is essential before the land itself fails.
- 4. Nutritional security — beyond calories: India achieved calorie sufficiency but still has the world’s largest number of malnourished people. Protein (pulses), micronutrients (zinc, iron, vitamin A), diverse diets are needed — not just wheat and rice calories.
- 5. Untapped eastern India: Assam, Bihar, Chhattisgarh, Jharkhand, Odisha, West Bengal, eastern UP — all have abundant water and fertile land but low productivity. This is India’s agricultural frontier for the next productivity revolution.
- 6. Small farmer income: 85% of India’s farmers have less than 2 hectares. Their incomes remain abysmally low. Doubling farmer incomes (PM’s target) requires technologies and systems designed specifically for small and marginal farmers — not just large commercial farms.
- 7. Export competitiveness: India needs to diversify agricultural exports beyond rice and wheat into fruits, vegetables, processed foods, spices, millets — higher-value crops that give farmers better incomes.
What the Second Green Revolution Should Achieve
✅ Objectives of the 2nd / Evergreen Revolution
- Crop diversification: Move beyond wheat-rice monoculture to pulses, oilseeds, millets (nutri-cereals), fruits, vegetables, spices. Millets especially — India declared 2023 as International Year of Millets at India’s initiative at UN.
- Sustainable farming: Reduce chemical fertilizer and pesticide dependence | Promote soil health | Organic farming | Natural farming (ZBNF) | Precision agriculture (right input, right place, right time, right quantity)
- Climate-resilient varieties: Develop crops that withstand heat, drought, flood, new pests — via conventional breeding, biofortification (nutritional enrichment), and regulated biotechnology
- Small farmer focus: Technologies affordable for small and marginal farmers | FPOs (Farmer Producer Organisations) | Digital agriculture (price info, weather alerts) | Better access to credit and markets
- Eastern India focus: Unlock the potential of India’s rain-rich eastern states — BGREI programme specifically targets this
- Nutritional security: Not just calories — biofortified crops (iron-rich rice, zinc-rich wheat, Vitamin A-rich sweet potato), pulses for protein, millets for multiple nutrients
- Water conservation: Drip irrigation, sprinkler, SRI (System of Rice Intensification), laser land levelling, crop diversification away from water-intensive paddy in overexploited areas

BGREI — Bringing Green Revolution to Eastern India
Budget 2010-11 · Under RKVY · 7 states · Rice-based cropping systems · Water potential
BGREI — Complete Profile
- Full name: Bringing Green Revolution to Eastern India (BGREI)
- Announced: Union Budget 2010-11 — recognizing the historical neglect of eastern India in agricultural development
- Programme status: Flagship programme under Rashtriya Krishi Vikas Yojana (RKVY)
- 7 Target States: Assam · Bihar · Chhattisgarh · Jharkhand · Odisha · West Bengal · Eastern Uttar Pradesh (Purvanchal)
- Focus: Addressing constraints limiting productivity of rice-based cropping systems | Harnessing water potential of eastern India which was hitherto underutilized
- Key interventions:
- Yield maximization of rice and wheat per unit area through improved agronomy, water harvesting and conservation
- Integrated Crop Management (ICM) practices for productivity improvement
- Cluster-based approach: demonstrations in farmer fields grouped as “clusters”
- Introduction of HYV seeds, better fertilizer management, pest control
- SRI (System of Rice Intensification) — uses less seed and water, higher yields
- Post-harvest management and marketing infrastructure
- Rationale — why eastern India? Eastern India has: abundant rainfall and river systems (Ganga, Brahmaputra, Mahanadi), fertile alluvial soils, large agricultural labour force — but LOW productivity compared to northwest. Punjab’s wheat yield is ~5,000 kg/ha while Bihar’s is ~2,200 kg/ha — same country, 2× gap. Closing this gap is the 2nd Green Revolution’s most important task.
- Impact: Bihar, Odisha, West Bengal have shown improved rice productivity since BGREI launch | Bihar in particular has shown remarkable rice yield growth — from being a backward state to demonstrating that the eastern potential CAN be unlocked

However, the revolution in India began in 1965-66 before the term was even coined. 2 ✅ C Subramaniam’s two-point formula: C Subramaniam became Food and Agriculture Minister in PM Lal Bahadur Shastri’s Cabinet in 1964. He proposed the critical two-point formula: (1) procurement of HYV seeds from abroad, and (2) guaranteed procurement prices to incentivize farmers to adopt new varieties. This political commitment was the decisive factor that made the Green Revolution possible in India. 3 ✅ 18,000 tonnes Mexican wheat seeds 1966: In 1966, MS Swaminathan convinced the Indian government to procure 18,000 tonnes of semi-dwarf Mexican wheat seeds (Sonalika and Kalyan Sona varieties developed by Norman Borlaug at CIMMYT). These were distributed in Punjab and Haryana, and yields surged dramatically — this is considered the beginning of India’s Green Revolution. 4 ❌ Statement 4 is WRONG — the critical answer: The First Green Revolution did NOT focus equally on all crops. It was overwhelmingly concentrated on wheat and rice (and to a lesser extent jowar, maize, bajra). Pulses, oilseeds, and millets received little attention. This selective focus is one of the biggest criticisms of the First Green Revolution — it solved the calorie crisis (wheat and rice give carbohydrates) but created a protein and micronutrient crisis by neglecting pulses and millets. India today is the world’s largest importer of edible oils and still faces a dal crisis — direct consequences of the First GR’s narrow crop focus.
📜 UPSC Previous Year Questions
Q. How was India benefited from the contributions of M.S. Swaminathan in the field of agricultural science?
[GS Paper III — 10 marks, 150 words]
📝 Model Answer Structure (10 marks, ~150 words)
Introduction (2-3 lines): MS Swaminathan (1925-2023), geneticist and “Father of India’s Green Revolution,” transformed India from a food-deficit “ship-to-mouth” economy to a net food exporter through his work in agricultural science over six decades. Key Contributions — Phase 1 (Green Revolution): (1) Collaboration with Norman Borlaug to adapt Mexican semi-dwarf wheat varieties to Indian conditions — persuaded government to procure 18,000 tonnes of HYV seeds in 1966 (birth of Green Revolution). (2) Development of Sonalika and Kalyan Sona wheat varieties suited to Indian soils. (3) IR-8 rice adaptation — “miracle rice” that could feed millions. (4) Wheat production rose from 12 MT (1964) to 20 MT (1970) — India declared self-sufficient in 1971. (5) Ended PL-480 food aid dependence — restored national dignity. Key Contributions — Phase 2 (Evergreen Revolution): (1) Recognized ecological damage of the 1st GR early — pioneer of sustainable agriculture discourse in India. (2) Coined “Evergreen Revolution” (1990): “productivity in perpetuity without ecological and social harm.” (3) Founded MSSRF (Chennai) — research on biodiversity, climate-resilient agriculture, women in farming. (4) Led National Commission on Farmers (2004-06) — recommended MSP at C2+50%, debt relief, land rights for women. (5) Championed biotechnology for food security while insisting on ecological safeguards. Legacy: India now produces ~330 MT foodgrains (2023-24 record), exports 18.5 MT rice, leads world in milk and pulses — foundations laid by Swaminathan’s scientific and policy contributions. His vision of Biohappiness (biodiversity + livelihood) continues through NMNF 2023, PKVY, and Digital Agriculture Mission. Conclusion: Swaminathan’s contributions represent two revolutions — feeding India through science, and then protecting India’s food future through sustainability. His Bharat Ratna (2024, posthumous) recognizes a lifetime of service that will shape Indian agriculture for generations.
Q. Explain various types of revolutions, took place in Agriculture after Independence in India. How have these revolutions helped in poverty alleviation and food security in India?
[GS Paper III — 15 marks, 200 words]
📝 Model Answer Points (15 marks, ~200 words)
Introduction: India’s post-independence agricultural transformation has been driven by a series of “revolutions” — each targeting a specific sector, addressing a specific crisis, and contributing to food security and poverty alleviation. Key Revolutions with Poverty/Food Security Impact: (1) Green Revolution (1965-78) — foodgrains: HYV seeds, chemical inputs, irrigation, mechanization | India from food deficit to surplus | 82 MT → 330 MT production | Ended PL-480 humiliation | Reduced rural poverty in Punjab, Haryana | BUT created regional inequality and neglected small farmers. (2) White Revolution / Operation Flood (1970-96) — dairy: Verghese Kurien + AMUL model | India #1 milk producer globally | 17 crore dairy farmers — many women, marginal | Transformed rural incomes in Gujarat and beyond | Cooperative model empowered farmers. (3) Blue Revolution — fisheries: India 2nd largest aquaculture producer | PM Matsya Sampada Yojana | 2 crore+ fisherfolk incomes improved. (4) Yellow Revolution — oilseeds (1986): Technology Mission on Oilseeds | Reduced edible oil import dependence | Sunflower, soybean, groundnut productivity up. (5) Golden Revolution — horticulture (1991-2003): Fruits (apple, banana, mango), vegetables, honey | India 2nd largest horticulture producer | Higher income per acre than cereals. Common thread — poverty alleviation: Rising agricultural productivity → higher farm incomes → rural poverty reduction → food availability → lower food prices for urban poor. The NSS data shows agricultural household income rose from ₹6,426/month (2013) to ₹10,218/month (2019) — most directly attributable to these revolutions. Limitations: Regional inequality (Punjab vs Bihar), crop concentration (wheat-rice), and environmental costs call for an Evergreen Revolution — sustainable, inclusive, and nutritionally secure. Conclusion: India’s agricultural revolutions represent the single most important driver of poverty reduction in post-independence India. Going forward, the Digital Agriculture Mission and NMNF will drive the next revolution.
This is a core UPSC Mains question that appears in multiple forms. Understanding this distinction is essential for high-scoring answers. First Green Revolution (1965-78) — The “Speed Over Sustainability” Approach: The First GR’s overriding objective was simple: produce more food, immediately. It succeeded dramatically — India went from chronic food shortage to food surplus in less than a decade. But the approach was: maximum chemical inputs + maximum water extraction + maximum mechanization → maximum yield. The ecological and social costs were secondary considerations. Results: groundwater depletion (Punjab’s aquifers being mined), soil degradation (declining organic matter, micronutrient deficiencies), chemical pollution (“cancer train”), regional inequality (only Punjab-Haryana-western UP), crop narrowness (only wheat and rice), and farmer exclusion (only large farmers benefited). Evergreen Revolution — Coined by MS Swaminathan in 1990: Swaminathan’s key insight was that the First GR was “eating the seed corn” — consuming natural capital (water, soil, biodiversity) that future generations needed. His definition: “Productivity improvement in perpetuity without ecological and social harm.” The key word is “perpetuity” — forever, not just for this generation. Four pillars: (1) Ecotechnology — use of biotechnology, precision agriculture, and IT, but guided by ecological principles rather than maximizing yield at any cost. (2) Conservation of biodiversity — maintain genetic diversity in crop varieties and ecosystems, not monocultures. (3) Social equity — benefits must reach small and marginal farmers, women in agriculture, tribal communities — not just large commercial farmers. (4) Climate resilience — develop crops and systems that can withstand extreme weather, since climate change will make the “gamble on monsoon” increasingly risky. Practical differences: Where GR1 said “maximum NPK fertilizer,” EGR says “right fertilizer, right time, right dose” (soil health card approach). Where GR1 said “extract maximum groundwater,” EGR says “drip irrigation + rainwater harvesting + crop diversification away from paddy.” Where GR1 said “monoculture HYV wheat-rice,” EGR says “diverse cropping systems including millets, pulses, horticulture.” Where GR1 ignored small farmers, EGR centres them through FPOs, cooperative models, and digital agriculture. Government schemes embodying the Evergreen Revolution: National Mission on Natural Farming (NMNF, 2023) — the most explicit EGR scheme, 15,000 clusters, zero external inputs. Paramparagat Krishi Vikas Yojana (PKVY) — organic farming clusters. NMSA — sustainable agriculture, soil health cards. Mera Pani Meri Virasat (Haryana) — incentivizes shift from water-intensive paddy. PM Pranam — incentivizes reduction in chemical fertilizer use. Digital Agriculture Mission — precision agriculture using AI and drones. International Year of Millets 2023 — India’s initiative to promote nutritional diversity. All these together represent the operationalization of Swaminathan’s Evergreen Revolution concept.
