Punjab govt. to give incentives to industries for using stubble

GS Paper 3

Topics Covered: Conservation and pollution related issues.

 

Context:

In an effort to check stubble burning menace during the paddy season, Punjab Government has announced a slew of measures.

 

Highlights:

  1. Certain categories of industries have been permitted to install paddy-straw-fired boilers to claim fiscal incentives.
  2. Cumulative fiscal incentives of ₹25 crore have been provided to the first 50 existing industries on ‘first come first serve’ basis for using paddy straw as fuel in boilers.
  3. Non-fiscal incentives to industries are in terms of availability of ‘Panchayat’ land for storage of paddy straw with lease agreement upto 33 years.
  4. Balers would be made available on priority in areas where paddy straw is used as fuel in boilers.

 

Significance:

The move would help in tackling the menace of stubble burning during harvesting of Kharif crops, thus also conserving the fertility of soil and saving the beneficial micro-organisms.

 

What is stubble burning?

It 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.

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

 

Why farmers opt for stubble burning?

  1. 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. With less income due 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:

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

 

Effects of Stubble Burning:

  • Pollution: Open stubble burning emits large amounts of toxic pollutants in the atmosphere which contain harmful gases like methane (CH4), Carbon Monoxide (CO), Volatile organic compound (VOC) and carcinogenic polycyclic aromatic hydrocarbons. They may eventually cause smog.
  • Soil Fertility: Burning husk on ground destroys the nutrients in the soil, making it less fertile.
  • Heat Penetration: Heat generated by stubble burning penetrates into the soil, leading to the loss of moisture and useful microbes.

 

Alternative solutions that can avoid Stubble Burning:

  1. Promote paddy straw-based power plants. It will 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. Incentives could be provided to those who are not burning the stubble and disincentives for those who continue the practice.
  2. 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.

 

Chhattisgarh Model:

An innovative experiment has been undertaken by the Chhattisgarh government by setting up gauthans.

  • A gauthan is a dedicated five-acre plot, held in common by each village, where all the unused stubble is collected through parali daan (people’s donations) and is converted into organic fertiliser by mixing with cow dung and few natural enzymes.
  • The scheme also generates employment among rural youth.
  • The government supports the transportation of parali from the farm to the nearest gauthan.
  • The state has successfully developed 2,000 gauthans.
