The news
The Commission for Air Quality Management (CAQM) has directed district authorities in Punjab to assess and verify farmland affected by paddy stubble burning, following a spike in farm fires and concerns over the reliability of burnt-area estimates. The directive was issued during a high-level review meeting chaired by CAQM Chairperson Rajesh Verma on Thursday, November 12, 2026, in three districts: Fatehgarh Sahib, Khanna, and Patiala.
According to satellite monitoring data from the Indian Agricultural Research Institute (IARI), a total of 10,466 paddy residue burning events were recorded across six monitored states and Delhi between September 15 and November 11, 2026, including 874 incidents on November 11 alone. While overall farm fires across the region declined by roughly 19.5% compared to the 13,002 events logged during the same period in 2025, Punjab recorded a 22.4% year-on-year increase, rising from 4,507 incidents in 2025 to 5,517 incidents so far this season, with 515 fires detected on November 11. The surge has been concentrated in districts such as Firozpur (728 events), Tarn Taran (687), Sangrur (628), Bathinda (499), and Patiala (374).
During the review, district authorities were directed to undertake assessment and ground-truthing of burnt areas, monitor ex-situ utilisation of paddy straw, ensure efficient use of crop residue management (CRM) machinery, and intensify information, education and communication (IEC) activities, officials said. In Fatehgarh Sahib, Verma directed officials to step up patrolling and satellite monitoring of fire hotspots, take strict action against violations, and provide support to farmers using CRM machinery. Closer coordination between the civil administration and police was also stressed to ensure a zero-burn season. Verma also visited an edible oil mill in Khanna to review the use of paddy straw as boiler fuel, and industries were urged to increase the use of paddy straw as fuel to reduce dependence on fossil fuels and prevent stubble burning.
Why in the news?
The CAQM has ordered ground verification of burnt farmland in Punjab after a spike in farm fires and an Indian Express report that burnt-area estimates remain unverified and unfinalised, highlighting gaps in monitoring methodology.
Why are burnt-area estimates unverified?
The Indian Agricultural Research Institute (IARI) stated in an RTI response that estimates of burnt areas in key agricultural states, including Punjab and Haryana, remain 'unverified' and 'unfinalised', and there is no standardised methodology to officially measure the extent of farmland burnt. The CAQM had constituted an expert committee led by the National Remote Sensing Centre in January 2024 to standardise a methodology for mapping burnt areas using satellite imagery, but the protocol remains under validation, with ground-truthing exercises revealing discrepancies between satellite-derived maps and observations on the ground.
What has the monitoring achieved and missed?
Regional fire events fell from 13,002 in 2025 to 10,466 in 2026 over the same monitoring window, while Punjab rose from 4,507 to 5,517. All other monitored states saw sharp year-on-year reductions: Madhya Pradesh dropped 34.9%, Rajasthan fell 12.8%, Uttar Pradesh declined 63.2%, Uttarakhand recorded a 55.6% drop, Haryana fell 50.8%, and Delhi dropped from 4 to 2 incidents. However, fire-event counts and burnt-area estimates measure different things: a count of detected fires cannot itself establish the acreage burnt. Punjab’s cumulative count remains far below earlier years — down from 7,029 in 2024, 23,730 in 2023, and 75,321 in 2020.
Farm fires: 2025 and 2026
| Region | 2025 | 2026 |
|---|---|---|
| All monitored regions | 13,002 | 10,466 |
| Punjab | 4,507 | 5,517 |
| Madhya Pradesh | 3,569 | 2,324 |
| Rajasthan | 1,577 | 1,375 |
| Uttar Pradesh | 2,224 | 818 |
| Haryana | 435 | 214 |
Facts and terms for exams
- Ground-truthing:
- Verification of remotely observed information through observations made at the actual location.
- Ex-situ residue utilisation:
- Use of crop residue outside the field where the crop was harvested, such as its use as industrial fuel.
- Satellite fire hotspot:
- A location identified through satellite observations as showing a thermal signal consistent with fire.
Why it matters for exams
Exams: UPSC
Syllabus: Environment: Air pollution and environmental monitoring; Agriculture: Crop residue management
Common mistake: Examiners may swap fire-event counts with verified burnt-area figures: the recorded fire counts do not establish the area burnt, and the mapping protocol remains under validation.
Mains question
Examine the challenges in monitoring and verifying stubble burning in Punjab. How can satellite-based mapping and ground-truthing improve enforcement under the CAQM framework?
Stuck? Get it in one tap
CAQM has asked Punjab districts to check how much farmland was affected by stubble burning. Ground-truthing means checking satellite observations at the actual location. Paddy straw can also be collected and used as fuel in industrial boilers instead of being burnt in fields.

- Q1Easy
Which body directed Punjab district authorities to verify areas affected by paddy stubble burning in November 2026?
Explanation: The Commission for Air Quality Management issued the district-level directions. The Indian Agricultural Research Institute provided monitoring data, the National Remote Sensing Centre led the mapping committee, and police officials participated in district coordination.
- Q2Hard
Consider the following statements about paddy residue monitoring in 2026:
- 1.The Commission for Air Quality Management directed district authorities to verify burnt areas in Punjab.
- 2.Punjab recorded a year-on-year decline in farm fires during 15 September–11 November.
- 3.The National Remote Sensing Centre led the expert committee on standardising burnt-area mapping.
Which of the statements given above is/are correct?
Explanation: Statements 1 and 3 are correct: CAQM issued the verification direction and the National Remote Sensing Centre led the committee. Statement 2 is incorrect because Punjab’s fire count rose by 22.4%.
- Q3Medium
How many paddy residue burning events were recorded in Punjab from 15 September to 11 November 2026?
Explanation: Punjab recorded 5,517 events in the 2026 monitoring window. The corresponding 2025 count was 4,507; 7,029 was Punjab’s 2024 count, while 10,466 was the 2026 regional total.
- Q4Medium
Why is ground-truthing important for satellite-based mapping of burnt farmland in Punjab?
Explanation: Ground-truthing checks satellite-derived maps against actual field observations, especially where discrepancies arise. It neither replaces residue machinery nor restricts monitoring to Delhi; fire counts do not directly provide verified burnt acreage.
