2-Minute Revision

The Second Green Revolution represents India's shift from input-intensive to knowledge-intensive agriculture, focusing on eastern states and sustainability. Unlike the First Green Revolution's concentration in northwestern states with wheat-rice monoculture, it emphasizes crop diversification, environmental sustainability, and technology integration across all regions, particularly Bihar, West Bengal, Odisha, and Assam.

Key technologies include precision agriculture using GPS and sensors, biotechnology for climate-resilient varieties, digital platforms for farmer advisory services, and water-efficient irrigation systems.

Major government schemes include National Mission for Sustainable Agriculture (₹3,300 crores) targeting rainfed areas and climate adaptation, Rashtriya Krishi Vikas Yojana providing flexible state funding, and Digital Agriculture Mission (₹2,817 crores) for technology integration.

Success stories include Bihar's 3.5% agricultural growth, Odisha's transformation to food surplus, and West Bengal's leadership in vegetable production. The revolution addresses First Green Revolution's limitations - environmental degradation, regional imbalances, and sustainability concerns - while promoting the 'more from less' philosophy through sustainable intensification and climate-smart agriculture practices.

5-Minute Revision

The Second Green Revolution, conceptualized in the 2000s and formally launched through various schemes, represents a paradigm shift in Indian agriculture from the input-intensive First Green Revolution to knowledge-intensive, sustainable farming.

The transformation addresses three key limitations of the First Revolution: environmental degradation through excessive chemical use, regional imbalances with benefits concentrated in northwestern states, and neglect of rainfed agriculture covering 60% of cultivated area.

The Second Revolution strategically targets eastern states - Bihar, West Bengal, Odisha, Assam, Jharkhand, and eastern UP - which account for 40% of cultivated area but contribute only 35% of food grain production despite favorable agro-climatic conditions.

Technological foundations include precision agriculture using GPS, sensors, and variable rate technology for optimized input application; biotechnology for developing climate-resilient crop varieties and bio-inputs; digital agriculture through mobile apps, satellite imagery, and AI-based advisory services; and climate-smart agriculture practices like conservation tillage and integrated pest management.

Major government schemes provide institutional support: National Mission for Sustainable Agriculture (₹3,300 crores) focuses on rainfed area development and climate adaptation; Rashtriya Krishi Vikas Yojana-RAFTAAR (₹15,722 crores) provides flexible funding for state-specific agricultural development; Per Drop More Crop promotes water-efficient irrigation with subsidies up to 55%; Soil Health Card scheme enables balanced fertilization; and Digital Agriculture Mission (₹2,817 crores) integrates advanced technologies.

Success stories demonstrate the revolution's potential: Bihar achieved 3.5% annual agricultural growth (2005-15) compared to national average of 3.2%; Odisha transformed from chronic food deficit to surplus through System of Rice Intensification; West Bengal leads in rice and vegetable production with highest potato productivity (23 tonnes/ha) in India.

Implementation challenges include limited technology adoption due to high costs and awareness gaps, inadequate rural infrastructure affecting market access, weak extension services with poor farmer-extension worker ratios, financial constraints limiting institutional credit access, and coordination challenges between central and state governments.

The revolution's environmental sustainability aspects include soil health management through organic matter enhancement, water conservation through micro-irrigation and rainwater harvesting, biodiversity conservation through indigenous variety promotion, and climate resilience through drought-tolerant and heat-resistant crop development.

Future prospects involve complete digitization of agricultural value chains, climate adaptation strategies, nutrition security focus through biofortification, and circular economy integration. The Second Green Revolution's success will be measured not just by production increases but by its ability to create sustainable, inclusive, and resilient agricultural systems ensuring food and nutrition security while preserving environmental resources.
