India's green revolution 2.0: from food security to a sustainable future

The Green Revolution in India marks one of the most significant transformations in the nation’s history, turning it from a food-deficient country into a self-sufficient agricultural powerhouse. Initiated in the 1960s under the guidance of scientists like Dr. M.S. Swaminathan and Nobel laureate Norman Borlaug, it was a policy and technology package designed to combat severe food shortages. However, the very success of this revolution brought new challenges, prompting a critical policy shift towards a more sustainable and climate-resilient future, often termed the Evergreen Revolution or Green Revolution 2.0.

Fun Fact: The term “Green Revolution” was first used by William S. Gaud, the administrator of the U.S. Agency for International Development (USAID), in a 1968 speech. He noted the “new revolution” was not a violent Red Revolution like that of the Soviets, nor a White Revolution like that of the Shah of Iran, but a “Green Revolution” based on the application of science and technology to agriculture.

The First Green Revolution: A Double-Edged Sword

The initial phase focused on increasing the production of food grains, particularly wheat and rice. This was achieved through a package of practices that fundamentally altered traditional farming.

The core components included:

1. High-Yielding Varieties (HYVs) of Seeds: Genetically modified seeds that could produce significantly more grain.
2. Chemical Fertilizers and Pesticides: Intensive use of synthetic inputs to provide nutrients and protect crops.
3. Irrigation: Expansion of irrigation infrastructure to ensure a reliable water supply.
4. Farm Mechanization: Introduction of tractors, harvesters, and other machinery.
5. Credit and Subsidies: Government support through agricultural credit, and subsidies on inputs.
6. Minimum Support Price (MSP): Guaranteed prices for produce to incentivize farmers.

While this model dramatically increased food grain production from 82 million tonnes in 1960 to over 176 million tonnes by 1990, its success was concentrated in states like Punjab, Haryana, and Western Uttar Pradesh. The long-term consequences soon became apparent, including depleted groundwater tables, soil degradation from chemical overuse, loss of biodiversity, and increased farmer debt.

The New Wave: Green Revolution 2.0 & Sustainable Agriculture

Recognizing the limitations of the first wave, India’s agricultural policy is now undergoing a paradigm shift. The focus is no longer just on production quantity but on ecological sustainability, economic profitability for farmers, and nutritional security. This new phase is driven by recent policy interventions and a focus on Climate-Smart Agriculture (CSA).

A landmark development is the launch of the National Mission on Natural Farming (NMNF) in November 2024. This centrally sponsored scheme aims to transition 1 crore (10 million) farmers to chemical-free, traditional farming methods. It emphasizes using on-farm biomass mulching, cow dung-urine formulations, and discourages all synthetic chemical inputs, directly addressing the soil health crisis.

Analogy: If the first Green Revolution was like a powerful but fuel-guzzling muscle car that won the race, the Evergreen Revolution is like a modern electric vehicle—equally powerful but efficient, intelligent, and gentle on the environment.

Critical Policy Appraisal

Statistic: Agriculture in India accounts for about 18% of the nation’s GDP but provides employment to nearly 50% of the workforce, highlighting its immense socio-economic importance and the need for sustainable growth.

Analytical Lens: UPSC Focus (Mains & Prelims)

Conceptual Basis

The legal and policy backbone for India’s food security objective, which the Green Revolution served, is now constitutionally enshrined through the National Food Security Act (NFSA), 2013. This act legally entitles a significant portion of the population to receive subsidized food grains, making sustained and sustainable agricultural production a national imperative.

UPSC Integration: Connecting the Dots

• GS Paper 3 (Economy): The topic is central to agricultural economics, including MSP, subsidies, PDS, food inflation, and farmer income. The shift to CSA is a key strategy for doubling farmers’ income.
• GS Paper 3 (Environment & Ecology): The environmental impacts of the first Green Revolution (eutrophication, water depletion, pesticide pollution) and the solutions offered by the Evergreen Revolution (natural farming, biodiversity) are core environmental topics.
• GS Paper 1 (Geography): It connects to cropping patterns, regional agricultural disparities, land use patterns, and the severe impact on groundwater resources in the Green Revolution belt.

Future Impact & Policy Relevance

The future of Indian agriculture hinges on successfully implementing this second, greener revolution. The policy shift, validated by the 2024 launch of the NMNF, indicates a strong political will to balance productivity with sustainability. The long-term impact will be a more resilient food system capable of withstanding climate shocks, improved soil health, reduced input costs for farmers, and better public health due to lower chemical residues in food. This transition is critical for achieving India’s Sustainable Development Goals (SDGs), particularly SDG 2 (Zero Hunger) and SDG 13 (Climate Action).

Prelims Practice Question (MCQ)

Who is known as the “Father of the Green Revolution in India” for his pivotal role in introducing and developing high-yielding varieties of wheat? a) Norman Borlaug b) Verghese Kurien c) M.S. Swaminathan d) C. Subramaniam

Answer and Explanation: c) M.S. Swaminathan. While Norman Borlaug is the “Father of the Green Revolution” globally, Dr. M.S. Swaminathan is revered as the “Father of the Green Revolution in India.” He was the visionary geneticist who worked with Norman Borlaug to adapt the new wheat varieties to Indian conditions and led the agricultural transformation within the country. Verghese Kurien is the father of the White Revolution (milk), and C. Subramaniam was the Minister for Food and Agriculture who played a crucial political role.

Mains Sample Question

Q. The first Green Revolution ensured India’s food security but at a significant ecological and social cost. In light of recent policy shifts like the National Mission on Natural Farming, critically analyze how the ‘Evergreen Revolution’ aims to create a more sustainable and equitable agricultural model for the future.
