• Direct Seeding of Rice (DSR): DSR technology allows for rice planting directly into the field, reducing the need for straw management and minimizing stubble burning.
  • Recent Example: In Punjab, DSR technology has been promoted by the government, with positive results in reducing stubble burning and improving rice yields.

b. Use of Crop Residue as Animal Feed or Biofuel

• Crop Residue Management: Incorporating crop residues into animal feed or using them for biofuel production can reduce the volume of stubble that needs to be burned.
  • Recent Example: Haryana has initiated programs to convert crop residues into fodder and bioenergy, helping farmers manage stubble sustainably.
• Biochar Production: Converting stubble into biochar, a type of charcoal used to improve soil fertility, offers an alternative to burning and helps sequester carbon.
  • Recent Example: Kerala has adopted biochar production from agricultural residues, contributing to improved soil health and reduced emissions.

c. Government Schemes and Support

• Subsidies for Machinery: The government provides subsidies for machinery like the Happy Seeder, which allows for the sowing of crops without the need for stubble burning.
  • Recent Example: In Punjab, the government has subsidized the purchase of Happy Seeders and other residue management tools to encourage adoption among farmers.
• Awareness and Training Programs: Educating farmers about the benefits of sustainable practices and providing training on alternative technologies are crucial for reducing stubble burning.
  • Recent Example: The Punjab State Council for Science & Technology has been conducting workshops and training sessions to promote sustainable residue management practices.

d. Policy and Regulatory Measures

• Strict Enforcement of Regulations: Implementing and enforcing regulations to control stubble burning can help mitigate its impact.
  • Recent Example: The Supreme Court of India has issued orders to enforce a ban on stubble burning in states like Punjab and Haryana, though enforcement remains a challenge.
• Promoting Research and Development: Investing in research for innovative technologies and practices that can replace stubble burning is essential.
  • Recent Example: The Indian Council of Agricultural Research (ICAR) is working on developing and promoting new technologies for efficient crop residue management.

4. Conclusion

Stubble burning significantly impacts air quality and public health in India, contributing to severe air pollution, environmental degradation, and climate change. Addressing these issues requires the adoption of sustainable agricultural practices such as zero-tillage, crop residue management, and the use of biochar. Government initiatives, including subsidies for machinery and awareness programs, play a crucial role in facilitating these alternatives. Strengthening policy measures and investing in research will further support the transition to more sustainable and environmentally-friendly agricultural practices.
