2-Minute Revision
Climate change significantly impacts Indian agriculture through rising temperatures, altered precipitation patterns, and increased extreme weather events. Key direct impacts include heat stress on staple crops like wheat and rice, leading to reduced yields and quality.
Erratic monsoons cause both droughts and floods, severely affecting rain-fed agriculture. Pest and disease dynamics are also changing, with warmer climates favoring their spread. Soil health degrades due to erosion and salinization.
India's policy response includes the National Action Plan on Climate Change (NAPCC) and its National Mission for Sustainable Agriculture (NMSA), which promotes climate-resilient practices. Schemes like Pradhan Mantri Fasal Bima Yojana (PMFBY) provide a safety net.
Adaptation strategies focus on Climate-Smart Agriculture (CSA), developing drought/heat-tolerant crop varieties, efficient water management, and integrated pest management. The challenge is complex, requiring a multi-faceted approach to ensure food security and farmer livelihoods, aligning with Sustainable Development Goals 2 and 13.
Vyyuha's CROPS-ADAPT mnemonic helps recall key aspects: Climate Risks, Operational Practices, Policy Support, Adaptation Techniques.
5-Minute Revision
The impact of climate change on Indian agriculture is a critical and multi-dimensional issue. Direct impacts stem from rising temperatures causing heat stress, shortening crop cycles, and reducing yields, particularly for wheat and rice.
Changing precipitation patterns manifest as erratic monsoons, leading to increased frequency and intensity of droughts and floods, which devastate rain-fed agriculture. Extreme weather events like cyclones, hailstorms, and unseasonal rains cause immediate and widespread crop damage.
These changes also alter pest and disease dynamics, favoring their proliferation and spread. Soil degradation, through erosion, salinization, and loss of organic matter, further reduces agricultural productivity.
Regionally, impacts vary significantly: coastal areas face sea-level rise and salinization, while the Indo-Gangetic Plains grapple with heat stress and monsoon variability, and the Himalayas experience chilling hour deficits for horticulture.
India's response is anchored in the National Action Plan on Climate Change (NAPCC), with the National Mission for Sustainable Agriculture (NMSA) as a key component promoting climate-resilient farming.
Other crucial policies include the Pradhan Mantri Fasal Bima Yojana (PMFBY) for crop insurance, and initiatives like Paramparagat Krishi Vikas Yojana (PKVY) for organic farming. Adaptation strategies emphasize Climate-Smart Agriculture (CSA), which integrates productivity, adaptation, and mitigation.
This involves developing drought/heat/flood-tolerant crop varieties (e.g., Swarna Sub1), implementing efficient water management techniques (micro-irrigation, rainwater harvesting), improving soil health, and adopting Integrated Pest Management (IPM).
The challenge is to scale these solutions, particularly for small and marginal farmers who are most vulnerable, ensuring food security and sustainable livelihoods in line with SDGs 2 and 13. Vyyuha's analysis highlights the need for integrated, farmer-centric, and regionally tailored approaches.
Prelims Revision Notes
For Prelims, focus on factual recall and conceptual clarity. Remember that Article 48-A (42nd Amendment) mandates environmental protection, and agriculture is a State Subject (Seventh Schedule). Key climate impacts include: Heat Stress (e.
g., wheat in IGP, reduced grain filling), Monsoon Variability (droughts, floods, delayed/early withdrawal), Extreme Weather Events (cyclones, hailstorms), Pest/Disease Shifts (new ranges, increased virulence), and Soil Degradation (erosion, salinization).
Important schemes: NAPCC (umbrella plan), NMSA (sustainable agriculture mission under NAPCC), PMFBY (crop insurance), PKVY (organic farming), NICRA (ICAR research). Key concepts: Climate-Smart Agriculture (CSA) (3 pillars: productivity, adaptation, mitigation), CO2 Fertilization Effect (potential yield boost, but often offset), Phenology Shifts.
Remember specific climate-resilient crop examples like Swarna Sub1 (flood-tolerant rice). Connect to SDG 2 (Zero Hunger) and SDG 13 (Climate Action). Be aware of recent data from Economic Surveys regarding agricultural performance and climate vulnerability.
Understand the general regional impacts across India's agro-climatic zones. Practice identifying direct vs. indirect impacts and policy vs. technological interventions. Vyyuha's CROPS-ADAPT mnemonic is a quick checklist for impacts and responses.
Mains Revision Notes
For Mains, structure is key. Introduction: Define climate change impact on agriculture, its significance for India. Body - Impacts: Categorize into direct (temperature, precipitation, extreme weather, pests, soil) and indirect (food security, farmer income, migration).
Provide specific Indian examples (e.g., wheat in Punjab, cotton in Maharashtra, apples in Himachal). Body - Challenges: Discuss socio-economic (small farmers, credit, awareness), institutional (extension, implementation gaps), and technological barriers.
Body - Policy Responses: Detail NAPCC (NMSA), PMFBY, PKVY, Per Drop More Crop, NFSM. Critically evaluate their effectiveness. Body - Adaptation Strategies: Explain CSA, resilient crop varieties, water management (micro-irrigation, rainwater harvesting), soil health (conservation tillage, organic farming), IPM, early warning systems.
Emphasize the need for regional variations in strategies. Vyyuha Analysis: Frame the issue as an intersection of environmental science, economic policy, and social justice. Highlight the disproportionate impact on vulnerable farmers and the need for inclusive growth.
Connect to SDGs (2, 13, 1). Conclusion: Summarize the need for a holistic, integrated, and farmer-centric approach for long-term climate resilience and sustainable development. Use data from Economic Surveys and NITI Aayog reports to strengthen arguments.
Practice using cross-references like for extreme weather events.
