WHY IN NEWS:
The region had experienced clean skies during the COVID-19 lockdown, but now, particulate matters have again increased

For PRELIMS keep an eye on losses and AQI .
For MAINS We have mentioned a few solutions at the end . Go through advantages and disadvantages too . Let us dive !
STUBBLE CROP BURNING
- Over the last 25 years, conservation cropping, which includes reduced soil cultivation and retention of crop stubble, has continued to evolve.
- More and more farmers recognise the benefits in terms of productivity and sustainability.
- Notwithstanding this, strategic burning of stubbles, based on sound agronomic principles, may occasionally be a valid option.
- Farmers should have flexibility to use this option when it is most appropriate.
- The air in the Indo-Gangetic Plains region of north India has started to become heavy.
- Some areas have entered the ‘poor’ category of air quality, especially in Delhi.
- The dominant pollutant was PM10, that could be a result of dust coming in from the west.
An AQI between
- 0 and 50 is considered ‘good’
- 51-100 (‘satisfactory’)
- 101-200 (‘moderate’)
- 201-300 (‘poor’)
- 301-400 (‘very poor’)
- 401-500 (‘severe’).
- Above 500 is the ‘severe-plus’ or ‘emergency’ category.
- COMBINE HARVESTING MECHANISM : Instead of penalising and prosecuting the farmers, our focus should be on developing the design of Combine Harvesters that do not leave the stubble behind.
- COLLECTION CENTRES : The State may consider setting up “Agri- waste Collection Centres” alongside the “Paddy Purchase Centres”, where the farmers may sell their agri-waste for a reasonable price and earn some additional income.
- SUBSIDIES : The industries which are converting this agri-waste/crop residue into wealth in the form of cattle feed or fuel briquettes, may also be suitably incentivised and subsidised.
- PREPARATION OF FIELD : Encourage and incentivise the farmers to go for early paddy, so as to give them enough time to harvest and thereafter prepare their fields for the next Rabi crop.
- ALTERNATE CROPPING METHOD : Encourage and educate the farmers to go for alternate fruit and vegetable crops, instead of paddy, that not only consume less water but also give better economic returns.
