Stubble burning is the deliberate setting fire of the straw stubble that remains after wheat and other grains have been harvested

Effects[edit]

There burning of stubble, contrasted with alternatives such as ploughing the stubble back into the ground has a number of consequences and effects on the environment^[1]

Stubble burning:

Quickly clears the field and is is cheap.
Kills weeds, including those resistant to herbicide, slugs and other pests.
Can reduce nitrogen tie-up

However, it has a number of harmful effects on the environment:

Loss of nutrients.
Pollution from smoke.
Risk of fires spreading out of control^[2]

There is a perception that stubble burning contributes to atmospheric CO₂. However Carbon dioxide releases are only slightly greater than those from natural decomposition^[1]

Attitudes to stubble burning[edit]

Stubble burning has been effecively prohibited since 1993 in England and Wales ^[3]. A perceived increase in blackgrass, and particularly herbicide resistant blackgrass have led to a campaign by some arable farmers for its return^[4].

In Australia stubble burning is "not the prefered option for the majority of farmers"^[1] but is permitted and recommended when there are circumstances where it is recommended. Farmers are advised to rake and burn windrows, and leave a fire break of 3 metres around any burn off.^[2]

In North America, fires are fairly common in Mid-western states. Many of the fires in the video are started deliberately.

In France, stubble burning is said to be fairly common.^{[citation needed]}

In China, there is a governmental ban on stubble burning, however the practice remains fairly common.^[5]
