Stubble Burning

What is Stubble Burning?

The practice of intentionally setting fire to the straw stubble and other plant residues that remain after harvesting crops, primarily paddy, to clear the fields for the next crop, leading to severe air pollution and environmental degradation.

Historical Background

The practice of stubble burning intensified in states like Punjab and Haryana following the Green Revolution, which promoted high-yielding varieties of paddy. The introduction of combine harvesters, coupled with the short window between paddy harvesting and wheat sowing, made burning a quick and cheap method for farmers to clear fields.

Key Points

8 points
  • 1.

    Causes of Burning: Short time gap between harvesting paddy and sowing wheat, lack of affordable alternatives for residue management, high cost of machinery, and lack of awareness.

  • 2.

    Environmental Impact: Major contributor to air pollution (PM2.5, PM10, black carbon, CO, NOx, SO2) in Northern India, especially during winter months, leading to 'Delhi Smog'.

  • 3.

    Soil Degradation: Causes loss of essential soil nutrients (nitrogen, phosphorus, potassium, sulfur), beneficial microorganisms, and organic matter, reducing soil fertility and moisture retention.

  • 4.

    Greenhouse Gas Emissions: Releases significant amounts of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), contributing to climate change.

  • 5.

    Health Hazards: Leads to respiratory diseases, eye irritation, skin allergies, and cardiovascular problems among farmers and urban populations.

  • 6.

    Alternatives: In-situ management (Happy Seeder, Super Seeder, Pusa bio-decomposer, mulching), ex-situ management (biomass power plants, bio-ethanol production, cattle feed, composting).

  • 7.

    Government Initiatives: Subsidies for farm machinery, awareness campaigns, legal prohibitions, Pusa bio-decomposer distribution, and formation of high-level committees.

  • 8.

    Economic Implications: While seemingly cost-effective for farmers in the short term, it incurs significant environmental and health costs for society.
