A technology-led sustainable solution to end stubble burning

The main barrier to stubble burning is not the lack of alternatives available but rather understanding the problem at the root level, and choosing, mobilizing, and implementing solutions that fit the purpose

Agriculture contributes to almost 17% of India’s GDP. While agriculture’s share of India’s GHG emissions is also in the same range, it spikes significantly during the months after harvesting due to the practice of crop stubble burning. Stubble burning refers to the practice of burning crop residue after harvesting grain crops.. Not only does it result in significant air pollution and soil degradation, it also has a huge health impact on millions of people. Sustainable practices in agriculture can be key to dealing with climate change, air quality and sustainable use of land and water. One significant step in that direction is tackling the issue of crop residue management and eliminating stubble burning. The main barrier to stubble burning is not the lack of alternatives available but rather understanding the problem at the root level, and choosing, mobilizing, and implementing solutions that fit the purpose. Upon closer inspection, one realises that though the solutions exist, pairing them with the right technology has been the missing link for its large-scale adoption. 

Finding the Right Sustainable Option
To find a solution and get it adopted widely, the concerns about its cost and scalability need to be addressed. A solution may provide the necessary outcomes, but devising a business case and justifying the investment in terms of men and material proves to be a bottleneck in its implementation. For example, farmers can avoid burning the stubble if they use a machine called a Happy Seeder. However, Happy Seeders require a high-powered tractor to plough the land, and since only 15% of tractors in India qualify, this solution becomes prohibitively expensive for most farmers. It’s unreasonable to expect that small farmers with low farm incomes will be able to afford to pay for such an expensive solution, and hence it’s not a viable solution for mass acceptance.  

This is where the PUSA bio-decomposer from the Indian Agriculture Research Institute (IARI) fits right into the picture. It is a bio-enzyme, which is sprayed onto the harvested stubble, after which the soil is rotated and irrigated for the next few days. This provides the PUSA fungi an ideal environment for decomposing the stubble, and if carried out with precision, within  days, the soil is ready for sowing the next crop. Besides taking care of the crop residue without burning, it improves soil quality and reduces the dependence on chemical fertilizers for the next crop. 

Digitising The Model For Cost & Service Efficiency
Digitization of service delivery provides an effective way of ensuring success of large scale solutions. Previously reaching to individual farmers was a trouble, but today, availability of smartphones and internet connectivity enables the flow of knowledge and solutions to the grassroots is seamless manner. 

Digital connectivity provides an opportunity for educating farmers about the benefits of adopting newer sustainable models and reinforcing the message to help with broadscale adoption. Since digitisation is still in its nascent stages with the agricultural community, group level or one on one trainings with farmers are often required to sensitise them on the existence of these solutions and the mode of availing them. Post this, apps designed in their vernacular can keep them in touch with information about best practices related to their crops, including benefits of regenerative practices like composting the stubble using the PUSA decomposer.

Given the nature of the end consumer, an amalgamation of physical and digital models works best, where field personnel sensitize the farmers and bring them on board, while the digital platform drives planning and efficient mobilization of the machines. For example in the case of decomposing stubble, once the farmer has downloaded the app, he/she can inform the service provider about his harvest date. The app can then allocate operators and deploy machines around this date to spray the bio-enzyme. Sensors on the spraying machine help with geo-tagging and analysing the area sprayed, thus making it easier to map operators and quantify the product usage. 

The digital model makes managing data, logistics, human resources allocation, and regular interventions with the farmers easier, thus significantly reducing the overall cost of the service model while improving its efficiency manifolds.

Tech Based Impact Monitoring
For years, Indian producers have been facing “digital darkness.” Innovation has been kept away from this primary workforce living and working in rural areas, turning the business of agriculture into an isolated one. Indian agriculture continues to face low technology penetration and lack of enough alternatives for sustainable agricultural practices. This results in higher input costs, degradation of water, air, and soil qualities, and lower agricultural incomes.

A similar situation exists while deploying a bio-spray to prevent stubble burning – its quantity, area sprayed, operator efficiency, spray efficacy, and whether or not it worked, or whether the farmer later resorted to stubble burning – needs to be analyzed to study the impact of the entire exercise. For this, independent knowledge bodies need to devise and monitor protocols for transparent impact analysis. Also, sensor-based information for tapping on-ground activities and satellite image mapping of the sprayed areas to check if the sprayed stubble was burnt at a later stage needs to be implemented. Digitization of the entire monitoring process extends transparency and credibility to the overall efficacy of the project and sheds light on its impact, efficiency, and scalability.

As a country that is still primarily an agri-based economy employing a majority of the workforce in its sector, India needs to recognize that agriculture is both part of the problem and part of the solution to climate change and sustainability. Not just stubble burning, but the country and its farmers need to seize every opportunity to shift away from inefficient farm practices and make a conscious shift towards long-term sustainability, efficiency, and resilience. Technology, the missing link till now, will definitely be the catalyst and the impetus that the Indian farmer has been seeking for nurturing a sustainable farm and a high-yielding agriculture business.

    Write more, that’s all I have to say. Literally, it
    seems as though you relied on the video to make your point.
    You obviously know what you’re talking about, why throw away your intelligence on just posting videos to
    your blog when you could be giving us something enlightening to read?

    I’m amazed, I have to admit. Seldom do I come across a blog that’s both equally educative and
    amusing, and without a doubt, you have hit the nail on the head.
    The issue is something which not enough people are speaking intelligently about.
    I am very happy I stumbled across this during my search for
    something concerning this.
