Stubble Burning

Every November, as you step out for Diwali celebrations, the air turns acrid and your throat catches—not from the firecrackers alone, but from the fields of Punjab and Haryana ablaze with stubble burning. This isn’t just a farmer’s quick fix; it’s a symptom of a system that has left agriculture gasping between two crops, and our cities choking on the smoke. Behind the orange haze lies a story of policy gaps, economic pressures, and a desperate search for balance between survival and sustainability.

What is stubble burning and why does it happen?

Stubble burning, also known as crop residue burning, is a widespread practice in Indian agriculture where farmers set fire to the leftover crop residue after harvesting. This phenomenon is deeply rooted in the agronomic and economic pressures faced by farmers in the country.

One of the primary reasons farmers resort to stubble burning is the immediate need to clear land for the next crop season. In India, the monsoon season brings a surge in rainfall, which can make the land unarable for several months. Farmers need to till the land and prepare it for the next crop, but the process is time-consuming and labor-intensive. Burning the crop residue provides a quick solution to clear the land and make it ready for the next crop.

Another significant factor driving stubble burning is the economic pressure on farmers. The Indian government has implemented policies like the Minimum Support Price (MSP) scheme to ensure that farmers receive a fair price for their crops. However, the MSP is often lower than the market price, leaving farmers with a significant loss. Burning the crop residue helps farmers to generate additional income by selling the charred remains as fertilizer or using them to produce biofuels.

For instance, the Indian company, ITC Limited, has been working to reduce its dependence on crop residue burning. The company has set up a biofuel plant in Haryana, which converts the crop residue into biofuels like ethanol and biodiesel. This initiative not only helps to reduce air pollution but also provides an alternative source of income for farmers.

Despite the negative impacts, stubble burning remains a widespread practice in Indian agriculture. However, initiatives like the one implemented by ITC Limited offer a glimpse of hope for a more sustainable future.

How did combine harvesters change the stubble problem?

Before combine harvesters, farmers cut and threshed by hand, leaving little residue and plenty of time to clear fields. But when the Green Revolution arrived in the late 1960s, machines replaced sickles. Combines sliced, threshed, and bagged grain in one pass, boosting yields and saving weeks of labor. This speed came with a hidden cost: the machines chopped stalks into short, dense stubble that stayed rooted in the soil—too tough to plough under and too abundant to burn safely. By the 1980s, combine use had spread across Punjab, Haryana, and western Uttar Pradesh, turning what was once a manageable 5–10 cm stubble into a 20–30 cm mat that choked the next wheat crop. Farmers now faced a brutal choice: spend days removing the stalks manually or risk a quick fire that would at least clear the field overnight. In 1998, the Punjab Agricultural University reported that combine adoption had jumped from 3 % of wheat area in 1970 to 68 % by 1995, while the number of farmer fire complaints to district offices rose in lockstep. The combine harvester had quietly flipped a seasonal nuisance into an annual pollution crisis.

Why can’t farmers just remove the stubble manually?

Why can’t farmers just remove the stubble manually? It might seem like a simple task, but for small and marginal farmers in India, manual stubble removal is not a viable option due to several labor, time, and cost constraints.

One of the main reasons is the sheer scale of land that needs to be tilled. In Punjab, where rice is a major crop, there are over 10 million hectares of land that require manual labor to remove stubble. This is a massive undertaking that would require a huge workforce, which many small farmers simply don’t have the resources to employ.

Another issue is the time it takes to complete the task. Manual stubble removal can be a labor-intensive process that requires farmers to spend hours each day, often in harsh weather conditions. This not only takes away from the time they can devote to other activities like planting and harvesting, but also means they have less time to focus on other aspects of their farm.

Finally, there’s the cost. Hiring laborers to help with stubble removal can be expensive, especially for small farmers who are already struggling to make a profit. The cost of hiring laborers, along with the cost of equipment and fuel, can add up quickly, making it difficult for farmers to break even.

For example, consider the case of a small farmer in Punjab who has 5 acres of land. If he were to hire laborers to help with stubble removal, he would need to pay them around ₹50,000 to ₹75,000 (approximately $700-$1,100 USD) per acre. This would translate to a total cost of ₹250,000 to ₹375,000 ($3,500-$5,250 USD) for the entire 5-acre farm. This is a significant burden for a farmer who is already struggling to make ends meet.

Cost	Per Acre	Total Cost (5 Acres)
Hiring Laborers	₹50,000 - ₹75,000	₹250,000 - ₹375,000

What are the alternatives to stubble burning?

Farmers don’t burn stubble out of choice; they burn because the clock is ticking and the combine harvester has just left a field carpeted with leftover stalks. So when we ask “what are the alternatives?”, we’re really asking: “What lets a farmer harvest rice, clear the field, and sow wheat—all inside a fortnight—without setting the crop residue on fire?”

Enter Happy Seeders: tractor-mounted machines that drill wheat seeds straight through the loose paddy straw, mulching the residue so it feeds the soil instead of choking it. In Punjab’s Fatehgarh Sahib district, over 4,500 farmers pooled resources to rent a fleet of Happy Seeders in the 2022–23 rabi season. By skipping the burn and the tillage, each hectare saved roughly ₹3,000 in diesel and 30 labour hours—numbers that turned sceptical neighbours into converts overnight.

When straw is too thick for Happy Seeders, bio-decomposers step in. These microbial cocktails—sprinkled with a little water and urea—break down stubble into nutrient-rich manure in 20–25 days. The Delhi government’s “Punjab Bio-Decomposer Project” handed out 18,000 kits in 2021; within a month, 30,000 acres around the capital had turned golden stubble into black gold, cutting smoke plumes that once blanketed the city each November.

A third path is turning straw into power. The 10 MW paddy-straw-based power plant in Fazilka, Punjab—run by a private developer with MNRE subsidies—consumes 180,000 tonnes of stubble annually, supplying clean electricity to 25,000 homes and earning farmers ₹2,500 per acre for their residue. The plant’s chimneys now rise where flames used to lick the sky, proving that crop waste can be a resource instead of a nuisance.

How does stubble burning affect air quality and health?

As the harvest season arrives in North India, a familiar sight can be seen in the fields - stubble burning. But have you ever wondered, how does stubble burning affect air quality and health? The answer lies in the tiny particles that are released into the air when stubble is burned. These particles, known as PM2.5, are so small that they can easily enter our lungs and cause respiratory problems. In fact, studies have shown that exposure to high levels of PM2.5 can lead to a spike in respiratory diseases such as asthma and bronchitis. For example, in 2019, the PM2.5 levels in Delhi skyrocketed to 999 micrograms per cubic meter, making it difficult for people to breathe. This is especially concerning for people who already have pre-existing medical conditions.

A great example of the impact of stubble burning can be seen in the story of a company called Bosch India, which has been working with farmers in Punjab to promote sustainable farming practices. By providing training and equipment to farmers, Bosch India has been able to reduce stubble burning in the region and improve air quality. This not only benefits the environment but also helps to improve the health and wellbeing of people living in the area. In fact, a study by the Indian Institute of Technology (IIT) found that if stubble burning is completely stopped, PM2.5 levels in Delhi can be reduced by up to 20%. This highlights the urgent need to address the issue of stubble burning and find alternative, sustainable solutions.

The effects of stubble burning are not limited to human health; it also has a significant impact on the environment. The smoke from stubble burning can travel long distances, affecting not just the local area but also neighboring cities and states. This has led to a broader environmental emergency in North India, with many cities experiencing hazardous air quality levels. To combat this, the government has launched initiatives such as the National Clean Air Programme, which aims to reduce PM2.5 levels by 20-30% by 2024. However, more needs to be done to address the root cause of the problem - stubble burning - and promote sustainable farming practices.

What laws exist to stop stubble burning and why do they fail?

What laws exist to stop stubble burning and why do they fail?

The National Green Tribunal (NGT) has issued several orders to curb stubble burning, but enforcement remains a challenge. One of the key laws is the Environment (Protection) Act of 1986, which prohibits activities that harm the environment, including stubble burning. However, despite these laws, stubble burning continues to be a major problem in India.

State penalties for stubble burning vary, but many states have implemented fines and penalties for those caught burning crop residue. For example, in Punjab, the government has imposed a fine of up to ₹50,000 and imprisonment for up to six months for stubble burning. However, these penalties are often not effectively enforced.

The ground realities that undermine enforcement are complex. In many cases, farmers are not aware of the laws and penalties, or they may not see the benefits of not burning stubble. Additionally, the lack of infrastructure for proper waste management and the high cost of alternative methods of crop residue management can also make it difficult for farmers to adopt sustainable practices.

A concrete example of the challenges of enforcing laws against stubble burning is the case of the Punjab government's efforts to curb stubble burning in the state's major agricultural hub, Ludhiana. In 2019, the government implemented a ban on burning crop residue, but despite the ban, many farmers continued to burn stubble, citing the high cost of alternative methods and the lack of effective enforcement.

State	Fine/Imprisonment
Punjab	Up to ₹50,000, up to 6 months imprisonment
Haryana	Up to ₹10,000, up to 3 months imprisonment
Uttar Pradesh	Up to ₹5,000, up to 1 month imprisonment

Despite these laws and penalties, stubble burning continues to be a major problem in India, with the country's air quality deteriorating significantly during the winter months. The NGT has issued several orders to curb stubble burning, but effective enforcement remains a challenge.

  What can students and cities do to reduce stubble smoke?

  As the monsoon season sets in, the air is filled with the pungent smell of stubble burning. The practice, which has been a part of Indian agriculture for centuries, is a major contributor to air pollution, particularly in the northern states of Punjab, Haryana, and Uttar Pradesh. But what can students and cities do to reduce stubble smoke and improve air quality?

  The answer lies in a combination of awareness campaigns, sustainable agriculture practices, and community involvement. For instance, the Indian government has launched initiatives such as the Fasal Bima Yojana, a crop insurance scheme that provides financial support to farmers who adopt sustainable agricultural practices. Similarly, companies like Mahindra & Mahindra have launched their own initiatives to reduce stubble burning, such as providing biofuel-powered tractors to farmers.

  One concrete example of a successful initiative is the "Stubble Buster" program launched by the Punjab government in 2019. The program provides financial incentives to farmers who adopt mechanical harvesting of their crops, reducing the need for stubble burning. Additionally, the program also provides training and support to farmers on sustainable agricultural practices.

  So, what can students and cities do to make a difference? Here are some actionable steps:

  • Support organizations that promote sustainable agriculture practices and reduce stubble burning.
  • Participate in awareness campaigns and spread the word about the negative impacts of stubble burning on air quality.
  • Encourage your local government to implement initiatives like the Fasal Bima Yojana or the Stubble Buster program.

  By working together, we can reduce the amount of stubble smoke in the air and improve the health and well-being of our communities.

  Key takeaways

  • Stubble burning is a time-saving but harmful practice driven by the 15–20 day gap between rice harvest and wheat sowing.
  • Mechanized harvesting (combine harvesters) post-Green Revolution worsened stubble accumulation, turning it into a crisis.
  • Manual removal is unaffordable for small farmers, while alternatives like happy seeders and bio-decomposers face adoption barriers.
  • Stubble smoke is a major contributor to North India’s winter air pollution, worsening respiratory health and visibility.
  • Existing laws (NGT orders, state penalties) fail due to weak enforcement, lack of farmer incentives, and economic compulsions.
  • The root cause is a broken agricultural economics model: high input costs, low crop prices, and no market for paddy straw.
