In News: The Delhi government will spray a bio-decomposer free of cost over 5,000 acres of paddy fields in the city this year, Environment Minister Gopal Rai said on Tuesday.

About Pusa Decomposer:

  • It is a bio-enzyme consisting of seven fungi that digest cellulose, lignin, and pectin in paddy straw.
  • It is developed by The Indian Council of Agricultural Research (ICAR)
  • It decomposes the stubble, turning it into manure, thus increases soil fertility, prevents stubble burning and reduces air pollution.

Causes of air pollution in Delhi in winters:

Every winter air pollution spikes in the national capital and adjoining areas due to multiple reasons

  • Slow wind speed
  • Bursting of firecrackers
  • Pollution from stubble burning
  • Household emissions including domestic biomass burning

Actions taken:

  • A list of emergency measures to control air pollution in Delhi-NCR, such as closing schools and stopping construction work, are undertaken each year during the winter months.
  • Graded Response Action Plan, prepared by the Commission for Air Quality Management, emergency measures will now be implemented based on predictions on air quality, three days in advance.
