Burning hay banned to improve air

THE Shanghai Environmental Protection Bureau said yesterday that burning hay will be banned during the World Expo to improve air quality, and will use satellite imagery to police the ban.

Hay burning is one of the major causes of local air pollution during the summer harvest in late May and early June and the autumn harvest in late October and early November, the bureau said.

The burning can generate many pollutants including small particulate matter, carbon dioxide and nitrogen oxides and reduces local air quality and the city's image.

Local authorities said the city can produce 1.3 million tons of hay a year which is mostly burnt by the farmers.

The city government wants farmers to make better use of the hay, like using it for fertilizer. The agricultural commission is studying ideas for scientific hay use.

Especially for this year's Expo, the city has reduced the amount of land allowed to grow wheat.
