Two years after the Supreme Court raised concerns over how agricultural fires are measured in India, the country still lacks a standardised mechanism to accurately assess the actual area burnt due to stubble burning.
While authorities routinely monitor and record the number of farm fires, the absence of a uniform system to measure the total land affected has raised questions about the accuracy of India's assessment of crop residue burning.
The gap is particularly significant as stubble burning remains a major concern during the post-harvest season, especially in northern states, where agricultural fires contribute to seasonal air pollution.
Fire Counts Do Not Reveal the Complete Picture
At present, satellite-based monitoring systems are widely used to identify and record agricultural fire incidents. These systems help authorities track the frequency and location of farm fires, providing important data for monitoring seasonal trends.
However, the number of detected fire incidents does not necessarily indicate the total area of farmland affected. A single fire incident may cover a relatively small patch or spread across a much larger agricultural field. Similarly, multiple fire detections may relate to the same burning event.
Without reliable burnt-area measurements, the actual extent of crop residue burning can remain difficult to establish.
Supreme Court Had Raised Concerns
The issue gained attention after the Supreme Court questioned the methodology used by authorities to assess agricultural fires. The court's concerns highlighted the need for more accurate and consistent measurements rather than relying exclusively on the number of fire incidents.
Two years later, the absence of a standardised assessment framework continues to raise questions about whether existing monitoring mechanisms provide a complete picture of the problem.
Why Accurate Measurement Matters
Reliable burnt-area data is essential for understanding the environmental impact of stubble burning and evaluating the effectiveness of government interventions. It can help authorities identify areas experiencing extensive crop residue burning, assess seasonal changes and develop more targeted strategies to discourage the practice.
Accurate measurements can also improve research into the relationship between agricultural fires and deteriorating air quality. Without consistent data, comparing the scale of stubble burning across different regions and years becomes challenging.
Need for a Uniform Monitoring Framework
Experts and environmental researchers have increasingly emphasised the importance of combining satellite observations, geographical data and ground-level verification to improve the assessment of agricultural fires.
A standardised methodology could help establish clearer estimates of the actual land area burnt and reduce inconsistencies in reporting.
Two years after the Supreme Court's intervention, the central question remains: If India can count its farm fires, why is it still unable to accurately measure how much farmland is actually burning?
