The northern parts of India and parts of Pakistan are severely affected by air pollution, which has led to accusations on both sides of the border.
Pakistani ministers have blamed the remnants of leftovers or mud burning after the harvest of large number of crops across the border, causing severe air pollution in Pakistani cities, especially Lahore.
During this part of the year, it is burned to remove the urine and feces for wheat harvest, which increases the air pollution hazardously.
On the other hand, an Indian politician also says that poisonous air that affects Delhi is coming from Pakistan or China.
But how much truth is there in their claim?
What have the politicians said?
Pakistani Minister for Environmental Change Zartaj Gill tweeted a photo of the US space agency NASA and said that fields are being set on fire after being harvested in India, which is causing smog in Lahore.
In response to his tweet, some people questioned his claim and asked if it was right to put the blame for pollution across the border.
Meanwhile, BJP leader Vinit Agarwal Sharda has blamed both Pakistan and China for pollution in India. They say that this ‘poisonous air’ has been released by one of the two countries, affecting the heart of Delhi
It’s not clear what he meant and what he was talking about. If that is the case with smog, which is caused by burning of mustard, then it must happen in India, including Pakistan, at this time of year.
How large is the frog being burned?
There is no doubt that at this time of the year a large number of fish are burnt by farmers in Haryana and Punjab in the state of India and the same happens in Punjab province of Pakistan.
However, satellite data from the US space agency NASA suggests that India can see more fires than Pakistan.
Pakistan’s city is close to the Indian border, so it can easily be affected by the smoke coming from across the border.
In spite of the measures taken to prevent the burning of foxes, the incidence of fire in India is apparently higher than it was last year.
According to the data of the state government of India in India, there were 42,676 incidents of fire from September 23 this year to November 6 this year, which is higher than the total number of incidents for the entire season of 2018 and 2017.
The incidence of burns is a major cause of the increase in pollution but it should also focus on other factors.
What are the other causes of pollution?
Weather conditions are also important during this time of year, which determines how far and in which air pollution goes.
After monsoon, during this period of burning, winds are moving from south to southeast so that pollution should go to India and not towards Pakistan.
But according to recent research by the American corporation Rand Corporation, it may change every year, depending on the air pressure and the time of burning.
It is difficult to predict the direction of the wind without weather information at a particular time, but pollution caused by the burning of India is likely to affect more than Lahore.
And like Delhi, there are a number of reasons for smog, such as smoke coming out of the vehicle, burning of garbage and industrial waste.
