A smoky haze hangs over India's northern plains and its capital, New Delhi, every year as winter sets in, raising fears for the health of many millions of people as authorities order fixes that do little to clear the air.
In recent days, the Air Quality Index in the capital of 20 million people, where few use air purifiers or wear masks to protect themselves, has risen above 350 on a scale of 500, near "very poor" levels, according to the SAFAR monitoring agency.
Prime Minister Narendra Modi's Bharatiya Janata Party does not govern Delhi - it is run by the opposition Aam Aadmi Party - and there's little cooperation between them.
It's nature that brings some improvement with warmer weather ending the atmospheric conditions that trap the smog before the return of the rains in around June.
