What is Green Revolution?
Historical Background
Key Points
12 points- 1.
The core of the Green Revolution was the introduction of High-Yielding Varieties (HYVs) of seeds. These seeds, primarily of wheat and rice, were genetically modified to produce significantly more grain per plant compared to traditional varieties. For example, the Sonora 64 wheat variety, developed in Mexico, was crucial in boosting wheat production in India. The 'why' is simple: more grain means more food, addressing the immediate crisis.
- 2.
The HYVs required a substantial increase in the use of chemical fertilizers. Traditional farming relied on natural fertilizers like manure, but these were insufficient to support the growth potential of the new seeds. Fertilizers like urea and diammonium phosphate (DAP) became essential inputs. The 'so what' is that this dependence on chemical fertilizers has long-term environmental consequences, including soil degradation and water pollution.
- 3.
Irrigation was another critical component. HYVs need a consistent and reliable water supply to reach their full potential. This led to the expansion of irrigation infrastructure, including canals, tube wells, and dams. The 'why' is that rain-fed agriculture is too unpredictable to support the intensive farming practices of the Green Revolution. Without irrigation, the HYVs would fail.
- 4.
Pesticides were introduced to protect the HYVs from pests and diseases. The high density of crops and the genetic uniformity of the HYVs made them vulnerable to outbreaks. Pesticides like DDT (now banned) and other chemicals were widely used. The 'so what' is that excessive pesticide use has led to environmental pollution, health problems, and the development of pesticide-resistant pests.
- 5.
The Green Revolution was heavily supported by government policies. These included subsidies for fertilizers and irrigation, price support for crops, and investment in agricultural research and extension services. The 'why' is that the government needed to incentivize farmers to adopt the new technologies and ensure that they had access to the necessary inputs. Without government support, the Green Revolution would not have been possible.
- 6.
The Green Revolution was not uniformly successful across all regions and crops. It was primarily concentrated in the irrigated areas of Punjab, Haryana, and Uttar Pradesh, and focused on wheat and rice. Other regions and crops, such as pulses and oilseeds, did not benefit as much. This led to regional disparities in agricultural development. The 'so what' is that it created an imbalance in agricultural production and income distribution.
- 7.
A major criticism of the Green Revolution is its environmental impact. The excessive use of fertilizers, pesticides, and irrigation has led to soil degradation, water pollution, and the depletion of groundwater resources. The 'why' is that the focus was on maximizing production in the short term, without considering the long-term sustainability of the agricultural system. This is the core of the current debate about pesticide use.
- 8.
The Green Revolution led to a shift from traditional farming practices to a more capital-intensive model. Small and marginal farmers often struggled to afford the new inputs and technologies, leading to increased indebtedness and landlessness. The 'so what' is that it exacerbated existing inequalities in rural areas.
- 9.
The Minimum Support Price (MSP) system was strengthened during the Green Revolution to provide farmers with a guaranteed price for their crops. This incentivized farmers to adopt the new technologies and increase production. However, the MSP system has also been criticized for distorting markets and encouraging the overproduction of certain crops. The 'why' is that it aimed to protect farmers from price fluctuations and ensure a stable income.
- 10.
The UPSC examiner will often test your understanding of the trade-offs involved in the Green Revolution. While it significantly increased food production, it also had negative environmental and social consequences. You need to be able to analyze these trade-offs and propose solutions for sustainable agriculture.
- 11.
The Green Revolution's success was also due to the establishment of agricultural universities and research institutions like the Indian Council of Agricultural Research (ICAR). These institutions played a crucial role in developing and disseminating new technologies and farming practices. The 'why' is that research and development are essential for continuous improvement in agriculture.
- 12.
The Green Revolution can be seen as a case study in the application of technology to solve a pressing problem. It demonstrates the potential of science and technology to transform agriculture and improve food security. However, it also highlights the importance of considering the broader social and environmental implications of technological interventions.

Recent Developments
10 developmentsIn 2022, the Indian government launched the PM-PRANAM scheme (Promotion of Alternate Nutrients for Agriculture Management) to reduce the use of chemical fertilizers and promote sustainable agriculture.
In 2023, several states have started promoting natural farming techniques, such as zero-budget natural farming (ZBNF), to reduce dependence on chemical inputs.
The Pesticides Management Bill, 2025, is currently under consideration in Parliament and aims to regulate the manufacture, import, sale, and use of pesticides to minimize risks to human health and the environment.
Research is ongoing to develop bio-pesticides and other alternatives to chemical pesticides to reduce their environmental impact.
The government is promoting the use of drones for pesticide application to improve efficiency and reduce exposure to farmers.
Several studies in 2023 and 2024 have highlighted the negative impacts of excessive pesticide use on soil health and biodiversity, leading to calls for more sustainable agricultural practices.
The government is encouraging the adoption of precision farming techniques, which use data and technology to optimize the use of inputs such as fertilizers and water.
The National Mission on Sustainable Agriculture (NMSA) is promoting climate-resilient agriculture and sustainable farming practices to address the challenges posed by climate change.
The focus is shifting towards promoting crop diversification to reduce dependence on water-intensive crops like rice and sugarcane.
The government is also promoting the use of organic farming practices to reduce the environmental impact of agriculture and improve soil health.

1 topicsFrequently Asked Questions
61. What's the most common MCQ trap regarding the Green Revolution's timeline?
Students often incorrectly associate the Green Revolution solely with the 1960s. While the initial phase was in the 1960s, its impact and expansion continued through the 1970s. MCQs might present options that limit the Green Revolution to only one decade, which is misleading. Remember it spans both the 1960s AND 1970s.
Exam Tip
When you see a date range, check if it includes both the 1960s and 1970s. If it only mentions one, it's likely incorrect.
2. Why do students confuse the goals of the Green Revolution with those of later agricultural policies, and what's the key difference?
The Green Revolution primarily focused on achieving food security by increasing production through HYVs, fertilizers, and irrigation. Later policies, like those promoting natural farming (PM-PRANAM scheme in 2022), focus on sustainability and reducing the environmental impact of agriculture. The key difference is that the Green Revolution prioritized QUANTITY, while later policies prioritize SUSTAINABILITY and quality.
Exam Tip
Remember: Green Revolution = Production, Later Policies = Sustainability.
3. The Green Revolution heavily relied on subsidies. What's the most common misconception about these subsidies that UPSC exploits?
The misconception is that subsidies were universally available to all farmers. In reality, the benefits were disproportionately reaped by farmers in irrigated areas like Punjab, Haryana, and Uttar Pradesh. MCQs often present statements suggesting equal access to subsidies nationwide, which is false. The regional disparity is a key point.
Exam Tip
Look for qualifiers like 'equally', 'all', or 'nationwide' when subsidies are mentioned. If present, question the statement's validity.
4. What problem did the Green Revolution solve that no other mechanism at the time could?
The Green Revolution uniquely addressed India's severe food security crisis in the 1960s and 70s. While imports (like under the PL-480 program) provided temporary relief, they were unsustainable and politically risky. The Green Revolution offered a pathway to self-sufficiency by dramatically increasing domestic production. No other existing mechanism could provide that level of rapid and substantial increase in food output.
5. What are the strongest arguments critics make against the Green Revolution, and how would you respond to them in an interview setting?
Critics argue that the Green Revolution led to environmental degradation (soil depletion, water pollution), regional disparities, and increased inequality among farmers. In an interview, acknowledge these drawbacks but emphasize the context: India faced a severe food crisis. The Green Revolution, while imperfect, averted widespread famine. Now, the focus should be on mitigating its negative impacts through sustainable practices like PM-PRANAM and promoting natural farming.
- •Acknowledge the validity of the criticisms regarding environmental and social impacts.
- •Highlight the historical context of food scarcity and the urgent need for increased production.
- •Emphasize the ongoing efforts to promote sustainable agricultural practices and address the negative consequences of the Green Revolution.
6. How does the Insecticides Act, 1968 relate to the Green Revolution, and why is the proposed Pesticides Management Bill, 2025 significant in this context?
The Insecticides Act, 1968, provided the initial regulatory framework for the use of pesticides, which were a key component of the Green Revolution. The Pesticides Management Bill, 2025, aims to replace it with stricter regulations to minimize risks to human health and the environment, addressing the negative consequences of excessive pesticide use during the Green Revolution. It signifies a shift towards more sustainable practices.
Exam Tip
Note the shift from regulation (Insecticides Act) to management (Pesticides Management Bill), indicating a more proactive approach.
