    Why does India need climate resilient agriculture

    Introduction

    India’s food system faces mounting stress from climate variability, declining soil health, and environmental degradation. Agriculture must simultaneously ensure food security for a growing population and adapt to rising climate risks. Conventional farming systems, particularly in rainfed regions, are proving inadequate under these pressures. Climate-resilient agriculture offers a pathway to sustain productivity while safeguarding ecological stability.

    Why in the news?

    Climate-resilient agriculture has gained renewed attention as India confronts increasing climate unpredictability, declining soil health, and rising pressure on food security. With nearly 51% of India’s net sown area being rainfed and contributing about 40% of total food production, climate variability poses a systemic risk to agricultural output and farmer livelihoods. 

    Why is Climate-Resilient Agriculture Necessary for India?

    1. Rainfed Agriculture Dependence: Nearly 51% of India’s net sown area remains rainfed, producing about 40% of national food output, increasing vulnerability to rainfall variability.
    2. Climate Variability Exposure: Erratic monsoons, heat stress, droughts, and extreme weather events directly affect crop yields and farm incomes.
    3. Population Pressure: Rapid population growth intensifies demand for reliable and stable agricultural productivity.
    4. Limits of Conventional Farming: Input-intensive methods show declining returns under climate stress and contribute to soil degradation and pollution.

    What is Climate-Resilient Agriculture (CRA)?

    1. Biotechnology Integration: Uses biofertilisers, biopesticides, and soil-microbiome analysis to reduce chemical dependence while maintaining productivity.
    2. Genomic Interventions: Enables development of genome-edited crops tolerant to drought, heat, salinity, and pests.
    3. Digital and AI-Based Tools: Applies AI-driven analytics to integrate climate and agronomic variables for location-specific advisories.
    4. Sustainability Orientation: Balances productivity enhancement with soil health and environmental protection.

    Where Does India Stand Today on CRA Adoption?

    1. Institutional Leadership: In 2011, the Indian Council of Agricultural Research launched the National Innovations in Climate Resilient Agriculture (NICRA) project.
    2. Technology Demonstration: CRA practices demonstrated across 448 climate-resilient villages.
    3. Key Interventions Implemented:
      1. Cropping Techniques: System of Rice Intensification (SRI), aerobic rice cultivation.
      2. Resource Efficiency: Zero-till wheat sowing, direct seeding of rice.
      3. Soil Management: In-situ incorporation of rice residues.
    4. Outcome: Enhanced adaptive capacity and resilience of farmers to climate variability.

    How Does the National Mission for Sustainable Agriculture Contribute?

    1. Productivity Enhancement: Focuses on improving yields, especially in rainfed regions.
    2. Integrated Farming Systems: Encourages crop-livestock-resource integration.
    3. Water Use Efficiency: Prioritises efficient irrigation and moisture conservation.
    4. Soil Health Management: Supports balanced nutrient use and organic matter restoration.
    5. Resource Synergy: Aligns conservation with productivity goals.

    What is the Role of Biotechnology and BioE3 Policy in CRA?

    1. Policy Positioning: BioE3 policy identifies CRA as a key thematic area for biotechnology-led solutions.
    2. Commercial Readiness: Several CRA-relevant technologies already commercialised.
    3. Bio-inputs Expansion: Companies supplying bio-inputs that improve soil health and reduce chemical dependency.
    4. Private Sector Participation: Signals transition from pilot-based models to scalable solutions.

    How is Digital Agriculture Strengthening Climate Resilience?

    1. AI-Enabled Advisory Services: Provide real-time, location-specific climate advisories.
    2. Precision Irrigation: Optimises water use under variable climatic conditions.
    3. Crop Health Monitoring: Enables early detection of stress and pest outbreaks.
    4. Yield Prediction Tools: Improve risk assessment and planning for farmers.

    Conclusion

    Climate-resilient agriculture is no longer optional for India’s food system. High dependence on rainfed farming, combined with climate volatility, necessitates a coordinated national strategy integrating biotechnology, digital tools, and institutional support. India’s early investments through NICRA, sustainable agriculture missions, and biotechnology policies provide a foundation, but scaling and coherence remain critical for long-term resilience.

  • Foreign Policy Watch: India – EU

    As EU carbon tax kicks in, India’s metal exports face price threat

    Introduction

    The European Union has begun implementing the Carbon Border Adjustment Mechanism (CBAM), imposing a carbon-linked levy on imports from carbon-intensive sectors. India, a major exporter of steel and aluminium to the EU, now faces higher compliance costs and potential loss of competitiveness. The mechanism represents a departure from tariff-based trade barriers towards climate-conditioned trade regulation, with significant implications for developing economies.

    Why in the News?

    CBAM has entered its implementation phase for the first time globally, covering carbon-intensive imports such as steel, aluminium, cement, fertilisers, electricity, and hydrogen. Indian metal exports to the EU now face an estimated price increase of 15-22%, creating a direct cost shock for exporters. The mechanism shifts climate action costs to exporting countries, raising concerns over equity, WTO compliance, and the future of South–North trade relations.

    What Is the EU’s Carbon Border Adjustment Mechanism (CBAM)?

    1. Carbon Pricing Mechanism: Imposes a levy on imported goods equivalent to the EU’s internal carbon price.
    2. Sectoral Coverage: Applies to steel, aluminium, cement, fertilisers, power, energy-intensive inputs.
    3. Objective Framing: Prevents carbon leakage by aligning import prices with EU climate standards.
    4. Operational Shift: Replaces implicit trade barriers with explicit climate-linked taxation.

    Why Are India’s Metal Exports Particularly Vulnerable?

    1. Export Concentration: India largely exports steel and aluminium to the EU, both CBAM-covered sectors.
    2. Production Technology: Indian steel manufacturing relies heavily on blast furnaces, which are more carbon-intensive.
    3. Scrap Constraint: Limited availability of steel scrap restricts transition to electric arc furnaces (EAFs).
    4. Cost Pass-through Limits: MSME exporters lack pricing power to absorb compliance costs.

    How Will CBAM Increase Export Costs for India?

    1. Price Impact: Estimates suggest a 15-22% increase in landed cost of Indian metal exports.
    2. Compliance Burden: Requires detailed plant-level emissions data, often unavailable with MSMEs.
    3. Default Emissions Risk: Absence of verified data may lead to higher default emission values.
    4. Competitiveness Erosion: Raises risk of market substitution by lower-carbon producers.

    What Are the Key Concerns Raised by Indian Exporters and Experts?

    1. Equity Concerns: Undermines the principle of Common but Differentiated Responsibilities (CBDR).
    2. Developmental Impact: Disproportionately affects developing economies with legacy infrastructure.
    3. WTO Compatibility: Raises questions on non-discrimination and disguised protectionism.
    4. Technology Lock-in: Penalises countries still transitioning to greener industrial processes.

    Why Is Scrap Availability Central to the Debate?

    1. Technology Divide: EAFs use scrap and emit less carbon than blast furnaces.
    2. Global Scrap Control: US, EU, and UK dominate scrap reserves and exports.
    3. Cost Advantage: Scrap-based producers face lower CBAM exposure.
    4. Structural Disadvantage: Indian producers lack access to adequate scrap volumes.

    What Is India’s Position on CBAM?

    1. Policy Opposition: India views CBAM as a trade barrier rather than a climate solution.
    2. Legal Standpoint: Challenges unilateral climate measures under multilateral trade norms.
    3. Negotiation Strategy: Seeks carve-outs for MSMEs and developing countries.
    4. Global Forums: Raises concerns at WTO and UNCTAD platforms.

    Does CBAM Meaningfully Address Climate Change?

    1. Limited Impact: Expected to mitigate only 0.1% of global CO₂ emissions.
    2. Exported Emissions: Risks shifting emissions geographically rather than reducing them.
    3. Technology Gap: Fails to support transition financing for developing countries.
    4. Policy Mismatch: Emphasises taxation over technology diffusion.

    What Are the Implications for Global Trade Governance?

    1. Precedent Setting: Encourages climate-linked trade barriers by developed economies.
    2. Fragmentation Risk: Weakens multilateral trade consensus.
    3. South-North Divide: Reinforces asymmetry in climate responsibility.
    4. Regulatory Spillover: UK and US considering similar mechanisms.

    Conclusion

    The EU’s Carbon Border Adjustment Mechanism marks a decisive shift in global climate governance by embedding carbon costs into international trade. While framed as a tool to prevent carbon leakage, its unilateral design risks undermining the principles of equity and common but differentiated responsibilities that anchor the global climate regime. For India, the immediate challenge lies in protecting export competitiveness without diluting climate commitments, while the larger task is to push for multilateral, finance- and technology-supported pathways to industrial decarbonisation. The future credibility of global climate action will depend on whether climate ambition is advanced through cooperative transition mechanisms or enforced through trade barriers that deepen developmental asymmetries.
