Context: The Commission for Air Quality Management (CAQM) has intensified action against stubble burning in Punjab following a recent spike in Delhi's air pollution.

  • Delhi's Environment Minister, Manjinder Singh Sirsa, attributed the deterioration in Delhi's air quality partly to farm fires in Punjab.
  • CAQM issued show-cause notices to Deputy Commissioners and senior police officers in nine districts and warned officials in 12 districts of personal accountability for enforcement failures.
  • Crop-residue burning is prohibited, with fines ranging from ₹5,000 to ₹30,000.
  • Despite a decline in farm-fire incidents over the last three years, the reduction has not translated into a significant improvement in air quality.

Why Does Stubble Burning Continue?

  • Economic constraints: In-situ crop-residue management is expensive, particularly for small and marginal farmers.
  • Inadequate biomass markets: Procurement of paddy straw for industrial use has not expanded sufficiently to provide farmers with reliable buyers and remunerative prices.
  • Limited machinery access: Farmers face difficulties accessing affordable machinery for collecting, transporting and managing crop residues.
  • Agricultural cycle constraints: Farmers have a narrow window between paddy harvesting and wheat sowing, encouraging quick disposal of crop residues.
  • Weather-related disruptions: Unusual weather conditions, including October rainfall, delayed harvesting and further compressed the time available for wheat sowing.
  • Inadequate returns: According to a recent CEEW study, farmers are increasingly removing straw from fields, but the financial returns remain insufficient for most of them.
  • Cropping pattern: Free electricity for irrigation encourages water-intensive paddy cultivation in Punjab, contributing to large-scale paddy straw generation.

Limitations in Monitoring Stubble Burning

  • Changing timing of farm fires: Studies by ISRO, the Council on Energy, Environment and Water (CEEW) and FOREST indicate that peak stubble burning has shifted from early afternoon to late afternoon and evening.
  • Satellite detection gaps: Satellites observe agricultural fields at fixed intervals. Fires occurring later may therefore remain undetected.
  • Need for ground verification: Satellite alerts must be verified by agriculture officials through field inspections to ensure accurate identification and reporting of violations.
  • CAQM's new portal: Links satellite-based evidence with field-level enforcement action to improve monitoring and accountability.

Institutional and Policy Measures

  • Commission for Air Quality Management (CAQM):
    • A statutory body established under the Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021.
    • Coordinates, monitors and implements measures to improve air quality in Delhi-NCR and adjoining areas.
    • Has powers to issue directions and coordinate action by State governments and other authorities.
  • Crop-residue management: Government interventions aim to promote machinery and alternative uses of paddy straw instead of open-field burning.
  • Biomass utilisation: Paddy straw can be collected and utilised as a raw material for industrial applications, including biomass-based energy generation.
  • Satellite monitoring: Remote sensing technology helps identify fire locations and monitor the spatial and temporal patterns of stubble burning.

Way Forward

  • Make straw collection economically viable: Develop reliable procurement systems and ensure remunerative prices for paddy straw.
  • Strengthen local collection networks: Establish decentralised collection, storage and transportation facilities to connect farmers with industries.
  • Improve machinery access: Expand affordable access to crop-residue management equipment, particularly for small and marginal farmers.
  • Promote industrial utilisation: Develop dependable markets for paddy straw in biomass-based power generation and other industrial applications.
  • Improve monitoring: Combine satellite-based alerts with timely ground-level verification by agriculture and enforcement officials.
  • Move beyond punitive measures: Enforcement should be accompanied by economic incentives and viable alternatives to burning.
  • Rationalise electricity subsidies: The article advocates ending free electricity for agricultural irrigation in Punjab to discourage excessive paddy cultivation and reduce the generation of crop residues.
  • Crop diversification: Encourage farmers to shift towards less water-intensive crops to reduce groundwater depletion and the environmental burden associated with paddy cultivation.

Important Concepts for UPSC

  • Stubble Burning: Deliberate burning of crop residues remaining in agricultural fields after harvesting, mainly to clear land quickly for the next cropping season.
  • In-situ Crop Residue Management: Managing crop residues within the field without removing them, using techniques such as mulching, incorporation into soil and specialised machinery.
  • Ex-situ Crop Residue Management: Collecting crop residues from fields and transporting them for alternative uses such as biomass energy, industrial fuel and other products.
  • Happy Seeder: A tractor-mounted machine that sows wheat directly into fields containing standing paddy stubble without requiring its burning or removal.
  • Biomass: Organic material derived from plants and animals that can be used as a source of energy or industrial raw material.
  • Remote Sensing: Collection of information about the Earth's surface through satellites or aircraft without direct physical contact; useful for monitoring agricultural fires and environmental changes.

Prelims Question

Q1. With reference to satellite-based monitoring of agricultural fires, consider the following statements:

  1. Satellite-based fire detection can underestimate actual farm-fire incidents because satellites observe agricultural fields at specific intervals.
  2. Ground-level verification is necessary to establish whether satellite-detected fire alerts correspond to actual violations.
  3. A shift in the timing of stubble burning from afternoon to evening can affect the effectiveness of existing satellite-based monitoring systems.
  4. Remote sensing requires direct physical contact with the Earth's surface to collect information about agricultural fires.

Which of the statements given above are correct?

(a) Only one
(b) Only two
(c) Only three
(d) All four

Answer: (c) Only three

Explanation:

  • Statement 1 is Correct: Fires occurring between satellite observation intervals may remain undetected.
  • Statement 2 is Correct: Ground verification by agriculture officials helps establish the actual occurrence of violations.
  • Statement 3 is Correct: Changes in the timing of farm fires, particularly towards late afternoon and evening, can create detection gaps.
  • Statement 4 is Incorrect: Remote sensing collects information without direct physical contact with the object or area being observed.
