2-Minute Revision

The Green Revolution, initiated in India in the mid-1960s, was a critical agricultural strategy to combat severe food shortages. Led by Dr. M.S. Swaminathan, it involved a 'package program' centered on High Yielding Variety (HYV) seeds for wheat and rice, coupled with intensive use of chemical fertilizers, pesticides, and assured irrigation.

This transformation primarily benefited well-irrigated regions like Punjab, Haryana, and Western Uttar Pradesh, leading to a dramatic increase in food grain production and achieving national food self-sufficiency.

While it averted famine and boosted rural incomes for many, it also created significant challenges. These included widening regional disparities, increased social inequality among farmers (benefiting large farmers more), and severe environmental degradation such as groundwater depletion, soil health decline, and chemical pollution.

The long-term sustainability concerns led to the concept of an 'Evergreen Revolution,' advocating for ecologically sound and equitable agricultural growth, marking an evolution in India's agricultural policy thinking.

5-Minute Revision

The Green Revolution represents a watershed moment in India's post-independence history, launched in the mid-1960s to address chronic food shortages and avert widespread famine. The strategy, spearheaded by agricultural scientists like Dr.

M.S. Swaminathan in India and Dr. Norman Borlaug globally, involved a comprehensive 'package program.' Its core components included the widespread adoption of High Yielding Variety (HYV) seeds, particularly for wheat (e.

g., Sonora 64) and rice (e.g., IR-8). These seeds were highly responsive to chemical fertilizers, whose usage increased exponentially, alongside pesticides and herbicides for crop protection. Crucially, assured irrigation through tube wells and canals was expanded to meet the water-intensive demands of HYV crops.

Farm mechanization also played a role in enhancing efficiency.

Geographically, the revolution was concentrated in regions with existing irrigation infrastructure and progressive farmers, primarily Punjab, Haryana, and Western Uttar Pradesh. The immediate economic impact was phenomenal: India achieved food self-sufficiency, transforming from a food-importing nation to one with buffer stocks.

This boosted agricultural productivity, increased farmer incomes in the beneficiary regions, and stimulated allied industries. However, the social consequences were mixed. While it reduced overall poverty and ensured food availability, it exacerbated regional disparities and increased inequality between large, resource-rich farmers and small, marginal farmers who struggled to afford the high input costs.

Environmentally, the Green Revolution left a significant footprint: groundwater depletion, soil degradation due to chemical overuse, water and soil pollution from pesticide runoff, and a loss of agricultural biodiversity due to monoculture.

Recognizing these limitations, the concept of an 'Evergreen Revolution' emerged, championed by M.S. Swaminathan, advocating for sustainable intensification—achieving productivity gains without ecological harm.

This shift emphasizes ecological farming, resource conservation, and inclusivity, aiming to balance food security with environmental sustainability and farmer welfare. For UPSC, understanding this evolution, the dual legacy of the Green Revolution, and its connections to contemporary challenges like climate change and farmer distress is crucial for a holistic analysis.

Prelims Revision Notes

The Green Revolution in India commenced in the mid-1960s, specifically with the launch of the New Agricultural Strategy in 1966-67. Key figures include Dr. M.S. Swaminathan (Father of Green Revolution in India) and Dr.

Norman Borlaug (Global Father of Green Revolution). The core technological components were High Yielding Variety (HYV) seeds, primarily for wheat (e.g., Sonora 64, Lerma Rojo 64A) and rice (e.g., IR-8, Jaya).

These seeds necessitated increased use of chemical fertilizers (nitrogenous, phosphatic, potassic), pesticides, and assured irrigation facilities (tube wells, canals). The revolution was concentrated in well-irrigated regions like Punjab, Haryana, and Western Uttar Pradesh.

Its primary achievement was India's attainment of food self-sufficiency, moving from a food-deficit to a food-surplus nation. Economic impacts included increased agricultural productivity, higher farmer incomes in beneficiary regions, and growth of allied industries.

Socially, it led to reduced poverty and improved food availability but also increased regional disparities and inequality among farmers. Environmental costs were significant: groundwater depletion, soil degradation, water pollution from chemical runoff, and loss of biodiversity.

The concept of 'Evergreen Revolution' advocates for sustainable agricultural growth, addressing the limitations of the original Green Revolution. Comparison with White Revolution (dairy, cooperatives) and Blue Revolution (fisheries) highlights different sectoral transformations.

Mains Revision Notes

The Green Revolution (mid-1960s) was a strategic response to India's food crisis, transforming agriculture through a technology-intensive 'package program.' For Mains, analyze its multi-dimensional impacts: Economic: Achieved food self-sufficiency, boosted food grain production (wheat, rice), increased farmer incomes (initially), stimulated allied industries.

However, it led to high input costs and farmer indebtedness. Social: Reduced poverty and hunger, improved food availability. But it exacerbated regional disparities (Punjab, Haryana, Western UP vs.

others) and social inequality (large vs. small farmers), and caused labor displacement due to mechanization. Environmental: Significant costs include groundwater depletion, soil degradation (nutrient imbalance, salinization), water and soil pollution from chemical runoff, and loss of agricultural biodiversity (monoculture).

Critical Evaluation: While a necessary evil for food security, its unsustainability and inequitable distribution of benefits are major criticisms. Contemporary Relevance: The 'Evergreen Revolution' (M.

S. Swaminathan) proposes sustainable intensification, ecological farming, and inclusivity to address GR's limitations. Current policies (climate-smart agriculture, organic farming, crop diversification, 'Per Drop More Crop') are direct responses to GR's legacy.

Connect to GS Paper 3 themes: food security, sustainable agriculture, rural development, environmental issues. Frame answers with a balanced perspective, acknowledging both successes and failures, and proposing forward-looking solutions.
