Why this question

North India faces severe air pollution in winters on account of several natural as well as anthropogenic factors. In this context it is essential to understand why the pollution has been less severe this year.

Directive word

Explain-here we have to make the concept in question, clear or easy to understand by describing or giving information about it.

Key demand of the question.

The question wants us to explain the reasons behind the low air pollution witnessed in Delhi before winters this year.

Structure of the answer

Introduction– write a few introductory lines about the  air pollution problem in Delhi and in India overall.

Body-

  1. Discuss why air pollution has been low before this winter in Delhi. E.g Burning of crop residue, blamed as the primary factor behind the smog that blankets the capital in the beginning of the winter season, has been substantially less so far this year; The Centre and northern states have taken measures this year to discourage farmers from a practice that they follow to prepare fields between the summer and winter crops. These measures, which include financial incentives to buy machines to manage farm reside, may have helped, but a key factor that has kept farmers from burning residue so far is the delayed harvest this year and untimely rains etc.
  2. Discuss any other factors which could increase the air pollution. E.g high vehicle emissions, cold temperature and incoming winds, stubble burning may increase etc.

Conclusion– based on your discussion, form a fair and a balanced conclusion on the given issue.
