Beyond the blaze: India's war on stubble burning & the policy pivot to a Bio-Economy

The Annual Choke: Why Stubble Burning Grips North India

Every year, as winter descends upon the Indo-Gangetic plains, a familiar, unwelcome guest arrives: a thick, grey haze that chokes cities, grounds flights, and sends millions gasping for breath. This is the direct consequence of large-scale crop residue burning, colloquially known as stubble burning. Primarily practiced in Punjab, Haryana, and Western Uttar Pradesh, farmers burn paddy straw left after harvest to quickly clear fields for sowing the next Rabi crop, wheat. This practice is a symptom of a larger agricultural crisis driven by mechanized harvesting (which leaves taller stubble) and a dangerously narrow time window between harvesting paddy and sowing wheat.

Historically, the government’s approach has been a mix of legal prohibitions and technological subsidies. Burning crop residue is an offense under Section 188 of the Indian Penal Code and the Air (Prevention and Control of Pollution) Act, 1981. Further, the National Policy for Management of Crop Residue (NPMCR), 2014, and a central sector scheme (2018-20) focused on subsidizing in-situ (on-field) management machinery like Happy Seeders and Super Straw Management Systems (Super SMS).

Despite these efforts, the problem has persisted, leading to a significant policy and judicial rethink in the last 18 months.

Analogy: Imagine a factory assembly line where one stage (harvesting) is super-efficient, but the next stage (sowing) needs the workspace cleared in just two weeks. For farmers, burning the leftover packaging (stubble) seems like the fastest, cheapest way to reset the line, even though it floods the entire factory floor with toxic smoke.

The New Policy Pivot: CAQM’s Enforcement and Market Creation

The narrative is changing, with the Commission for Air Quality Management (CAQM) and the Supreme Court leading a fresh charge. Frustrated with tepid state-level enforcement, the focus has dramatically shifted from a subsidy-only model to a more holistic strategy emphasizing strict enforcement, accountability, and the creation of a viable market for stubble.

Recent Developments (2024-2025):

• CAQM’s Assertive Stance (May 2025): Acting on a Supreme Court mandate, the CAQM issued a comprehensive set of mandatory directions. Key among these is the formation of a dedicated “Parali Protection Force” at district levels for stringent vigilance. This represents a move towards fixing administrative accountability, a point repeatedly stressed by the Supreme Court in late 2024 and 2025 hearings where it reprimanded states for their efforts being “mere eyewash.”
• Updated CRM Guidelines (March 2024): The Union government released the latest Crop Residue Management (CRM) guidelines, introducing crucial changes. For the first time, an 80% subsidy is available for high-horsepower (60 HP+) tractors for Custom Hiring Centres (CHCs), addressing a key operational bottleneck for farmers. The guidelines also shifted from direct benefit transfers to a credit-linked capital subsidy mechanism, enhancing accountability for beneficiaries.
• Strengthening Ex-Situ Management: The most significant shift is the push for ex-situ (off-field) solutions. The 2024 CRM guidelines provide robust financial models for entrepreneurs to set up paddy straw supply chains. This is complemented by the Ministry of Power’s revised policy (May 2024), which mandates that certain coal-based thermal power plants must co-fire 5% biomass pellets starting in 2025, ramping up to 7% two years later. This creates a guaranteed market for stubble, transforming agricultural waste into a valuable resource.
• Expanding Biomass Use (July 2025): The CAQM directed brick kilns in non-NCR districts of Punjab and Haryana to co-fire paddy straw-based pellets, targeting 50% usage by November 2028, further expanding the market.

Fun Fact: India generates an estimated 500-550 million tonnes of crop residue annually. If even a fraction of the burnt paddy straw was converted into briquettes, it could replace a significant amount of coal in thermal power plants, contributing to India’s climate goals.

In-Situ vs. Ex-Situ: A Tale of Two Solutions

The battle against stubble burning is being fought on two fronts: managing the residue within the farm (in-situ) and taking it away for other uses (ex-situ). Both have distinct advantages and challenges.

Statistic: Co-firing just 5-7% biomass pellets in India’s thermal power plants could prevent an estimated 38 million tonnes of carbon dioxide emissions annually.

Mnemonic for Comprehensive Solutions (CREATE):

To remember the multi-pronged strategy needed to tackle stubble burning, use the mnemonic CREATE:

• C - Co-firing & Circular Economy (Promoting industrial use)
• R - Rural Entrepreneurship (Supporting biomass aggregators)
• E - Enforcement & Education (Strict action by CAQM & farmer awareness)
• A - Alternative Technologies (Subsidizing In-situ machines & bio-decomposers)
• T - Timely Incentives (Financial support for non-burning)
• E - Economic Viability (Ensuring profitability for farmers and industries)

Critical Policy Appraisal

Despite recent progress, the path to zero-burning is fraught with challenges. The policy must balance environmental imperatives with the economic realities of farmers.

Analytical Lens: UPSC Focus (Mains & Prelims)

Conceptual Basis:

• Primary Legislation: Air (Prevention and Control of Pollution) Act, 1981; Environment Protection Act, 1986.
• Statutory Body: The Commission for Air Quality Management (CAQM) in NCR and Adjoining Areas Act, 2021 is the central legal instrument in recent actions.
• Judicial Intervention: The Supreme Court’s ongoing engagement in cases like M.C. Mehta vs. Union of India has been a key driver of policy changes.

UPSC Integration: Connecting the Dots

• GS-3: Environment & Ecology: Direct link to air pollution (PM2.5, black carbon), soil degradation (loss of organic carbon), and climate change mitigation (reducing GHG emissions).
• GS-3: Indian Economy: Connects to agricultural economics (farmer income, mechanization), subsidies, infrastructure, and the emergence of a circular economy and bio-energy sector.
• GS-2: Governance & Polity: Involves policy implementation, Centre-State relations, the role of statutory and regulatory bodies (CAQM, CPCB), and judicial activism.

Future Impact & Policy Relevance:

The long-term strategy is clearly moving beyond just pollution control to building a sustainable bio-economy around agricultural residue. Success will depend on making the ex-situ management chain economically attractive for every stakeholder, from the farmer to the power plant. The policy shift from punitive measures to creating positive economic incentives (turning ‘parali’ from a liability into an asset) is the most critical pivot. This approach not only addresses pollution but also aims to supplement farm incomes and create rural jobs, aligning with the goal of doubling farmers’ income.

Prelims Practice MCQ:

Which of the following bodies has been recently vested with statutory powers to issue binding directions to states like Punjab and Haryana for the management of crop residue burning?

a) National Green Tribunal (NGT) b) Central Pollution Control Board (CPCB) c) Commission for Air Quality Management (CAQM) d) Ministry of Agriculture & Farmers Welfare

Explanation: The correct answer is (c) Commission for Air Quality Management (CAQM). The CAQM was established by an Act of Parliament in 2021 with specific powers to coordinate and take measures to control air pollution in the National Capital Region and adjoining areas, including issuing legally binding directions to state governments on issues like stubble burning. While NGT and CPCB have roles in environmental regulation, the CAQM is the specialized body now spearheading this effort.

Mains Sample Question (15 Marks):

“Despite a slew of legislative and technological interventions, crop residue burning remains a persistent challenge. Critically analyze the reasons for this policy gap and suggest a holistic framework that balances environmental concerns with the economic realities of Indian farmers, in light of recent governmental initiatives.”
