• Stubble burning has been effectively prohibited since 1993 in the
United Kingdom. A perceived increase in
blackgrass, and particularly herbicide resistant blackgrass, led to a campaign by some arable farmers for its return. • In
Australia stubble burning is "not the preferred option for the majority of farmers" • In the
European Union, the
Common Agricultural Policy strongly discourages stubble burning. • In
China, there is a government ban on stubble burning; however the practice remains fairly common. • In northern
India, despite a ban by the Punjab Pollution Control Board, stubble burning is still practiced. Authorities are starting to enforce this ban more proactively, and to research alternatives.
India ,
Punjab, India Stubble burning in
Punjab,
Haryana, and
Uttar Pradesh in north India has been cited as a major cause of
air pollution in Delhi since 1990. Consequently, the government is considering implementation of the 1,600 km long and 5 km wide
Great Green Wall of Aravalli. The smog that arises from the burning contributes fine black and brown carbon into the atmosphere which affects light absorption. of crop waste from their wheat and paddy fields after harvesting as a low-cost straw-disposal practice to reduce the turnaround time between harvesting and sowing for the first (summer) crop and the second (winter) crop. Smoke from this burning produces a cloud of particulates visible from space and has produced what has been described as a "toxic cloud" in New Delhi, resulting in declarations of an air-pollution emergency. For this, the NGT (National Green Tribunal) instituted a fine of ₹2
lakh on the Delhi Government for failing to file an action plan providing incentives and infrastructural assistance to farmers to stop them from burning crop residue to prevent air pollution. Although harvesters such as the Indian-manufactured "
Happy Seeder" that shred the crop residues into small pieces and uniformly spread them across the field are available as an alternative to burning stubble, and crops such as
millets and
maize can be grown as a sustainable alternative to rice and wheat in order to conserve water, some farmers complain that the cost of these machines is a significant financial burden, with the crops not incurred under MSP prices when compared to burning the fields and purchasing crops that are produced under MSP prices. In May 2022, the Government of Punjab announced they will purchase
maize,
bajra,
sunflower and
moong crops at MSP, encouraging farmers to adopt less water consuming options as a sustainable alternative to paddy and wheat in the wake of fast-depleting groundwater.
Pollution from stubble burning in India A recent study in 2020 showed that the country created 600-700 million tonnes of crop residue and is choking cities. People in India are awaiting sustainable management to reduce the pollution. The areas that are largely contributing to the stubble burning pollutants are Uttar Pradesh, Punjab, and Haryana which is spreading to the border of Uttarakhand. is exhausting natural resources like water, soil, and forest areas. In one year the emissions from the crop burning can be 17 times the total annual particulate pollution all of which have large investment returns ==See also==
