Stubble burning

 

What to study?

For Prelims and Mains: Crop burning- why, concerns, effects on environment and health, their regulation and the need for a comprehensive policy on this.

 

Context: Centre, Punjab at odds over stubble burning.

Why? Both the Central and State governments have released data on stubble burning, but with starkly different narratives.

  • As per the Centre, the events had declined 19% this year, including a 16.8% reduction in Punjab.
  • As per Punjab, there is an increase of 2.3% in the number of incidents.

 

What is stubble burning?

Stubble burning is a common practice followed by farmers to prepare fields for sowing of wheat in November as there is little time left between the harvesting of paddy and sowing of wheat. 

Stubble burning results in emission of harmful gases such carbon diaoxide, sulphur dioxide, nitrogen dioxide along with particulate matter.

 

Concern of the Farmers: Why they opt for stubble burning?

  1. Even though farmers are aware that the burning of straw is harmful to health, they do not have alternatives for utilising them effectively.
  2. The farmers are ill-equipped to deal with waste because they cannot afford the new technology that is available to handle the waste material.
  3. Experts say that with less incomedue to crop damage, farmers are likely to be inclined to light up their fields to cut costs and not spend on scientific ways of stubble management.

 

Advantages of stubble burning:

  1. It quickly clears the field and is the cheapest alternative.
  2. Kills weeds, including those resistant to herbicide.
  3. Kills slugs and other pests.
  4. Can reduce nitrogen tie-up.

 

What’s the issue?

Stubble burning is adversely affecting environment and public health. The problem has not been fully tackled and the adverse impacts on the air quality and consequent impacts on the citizens’ health and lives are undisputed.

 

Alternative solutions that can avoid Stubble Burning:

  1. There is great potential for making investments in paddy straw-based power plants which can help avoid stubble burning to a large extent and also create employment opportunities.
  2. Incorporation of crop residues in the soil can improve soil moisture and help activate the growth of soil microorganisms for better plant growth.
  3. Convert the removed residues into enriched organic manure through composting.
  4. New opportunities for industrial use such as extraction of yeast protein can be explored through scientific research.

 

What needs to be done- Supreme Court’s observations?

  1. The problem is required to be resolved by taking all such measures as are possible in the interest of public health and environment protection.
  2. Incentives could be provided to those who are not burning the stubble and disincentives for those who continue the practice.
  3. The existing Minimum Support Price (MSP) Scheme must be so interpreted as to enable the States concerned to wholly or partly deny the benefit of MSP to those who continue to burn the crop residue.
  4. Secretary, Union Ministry of Agriculture and Farmers’ Welfare has also been directed to be present to “find a lasting solution.”
  5. The Central government should convene a meeting with the States.
