Introduction
India achieved a record foodgrain production of 3,577.3 LMT in agricultural year 2024-25, cementing self-sufficiency. However, accelerating climate volatility directly threatens Sustainable Development Goal 2 (Zero Hunger) by disrupting all four dimensions of food security: availability, accessibility, utilization, and stability.
Major Challenges and Impact Mechanisms
- Terminal Heat Stress: Unseasonal temperature spikes during February and March curtail the crucial grain-filling stage of Rabi wheat, with projections indicating a potential yield decline of up to 19.3% by 2050 (ICAR-NICRA).
- Monsoon Volatility and Moisture Stress: Erratic monsoon onset, extended break spells, and intense precipitation events disrupt the vegetative sowing cycle of rainfed Kharif staples such as paddy and pulses.
- Nutritional Depletion (Hidden Hunger): Elevated atmospheric carbon dioxide concentrations alter crop physiology, diluting essential micronutrients like zinc and iron while lowering protein levels in staple cereals, directly impairing food utilization.
- Regional Agro-Ecological Vulnerabilities:
- Indo-Gangetic Plains: Severe wheat yield losses driven by heat extremes and rapid groundwater depletion.
- Central and Peninsular India: Rainfall volatility leading to acute moisture stress for rainfed pulses and oilseeds.
- Coastal Belts: Recurrent cyclonic storm surges and sea-level rise inducing soil salinisation and destroying paddy tracts.
Measures for Sustainable and Climate-Resilient Food Security
- Promotion of Climate-Smart Agriculture (CSA): Scale up climate-resilient, biofortified, and stress-tolerant crop cultivars—such as drought-tolerant Sahbhagi Dhan—under the National Innovations in Climate Resilient Agriculture (NICRA) framework, alongside mainstreaming climate-hardy millets (Shree Anna).
- Sustainable Input and Resource Management: Rationalize chemical fertilizer application via PM-PRANAM to restore soil microbial health, and deploy solarized micro-irrigation systems under PM-KUSUM to maximize crop-per-drop efficiency in water-stressed zones.
- Post-Harvest and Cold-Chain Modernization: Establish decentralized, solar-powered cold storages and hermetic silos at farm gates to curb weather-induced post-harvest losses, particularly across perishable horticulture crops.
- Agro-Ecological Diversification: Shift regional cropping patterns away from water-intensive monocultures in arid zones toward agro-forestry, integrated farming systems, and regenerative soil practices.
Conclusion
To safeguard long-term national food sovereignty, India must transition from a calorie-centric production model to a decentralized, nutrition-sensitive, and climate-adaptive framework. Embedding climate resilience across the food supply chain is vital to withstand planetary warming while fulfilling the mandate of zero hunger.
