Canada – June 24th, 2013

Haze hangs over the Gulf of Saint Lawrence in Canada. The haze is possibly caused by smoke from wildfires burning to the northwest. The Gulf of Saint Lawrence is the world’s largest estuary and the outlet of the Great Lakes of North America via the Saint Lawrence River into the Atlantic Ocean. The gulf is a semienclosed sea, covering an area of about 236,000 square kilometres (91,000 sq mi) and containing about 35,000 cubic kilometres (8,400 cu mi) of water, which results in an average depth of 148 meters.

Haze Over Eastern China

China – June 12th, 2013

Here, haze can be seen over the eastern part of China, near the Bohai Sea. China is the world’s largest emitter of carbon dioxide (pumping out some 10 gigatons of carbon dioxide in 2011), and has vowed to reduce such emissions per unit of gross domestic product by 40 to 45 percent of the country’s 2005 levels by 2020.

However, scientists have suggested that current efforts to cut harmful greenhouse gases fall short because of the way they set targets for the highest polluting areas. China’s lesser-developed heartland is actually responsible for 80 percent of carbon dioxide emissions related to goods consumed along the wealthier coast.

Smoky Haze Over Myanmar and China

Myanmar and China – April 19th, 2013

A cloud of smoke and haze hangs over northern Myanmar and southeastern China. In the full image, square markers indicate the exact locations of many of the fires contributing to the haze. Although the cause cannot be discerned through the imagery, fires in this region at this time of year are often set by farmers wishing to clear fields for planting.

Haze Over Northwestern Italy

Italy – April 17th, 2013

A haze hangs over the northwestern part of Italy, over the Po Valley and along the coast to the French border, also spilling over the Mediterranean Sea towards the island of Corsica. Visible on the other side of the Italian peninsula, in the Adriatic Sea, are green sediments and algae spilling forth from the mouth of the Po River.

Thick Haze from Agricultural Fires in Thailand

Thailand and Myanmar – April 8th, 2013

Agricultural fires burning across Thailand create a thick haze over the country and its neighbors, including Myanmar. The Thai government is stepping up efforts to fight forest fires and haze pollution by applying stricter law enforcement, especially during the critical period from January to April. Haze pollution can cause such health hazards as respiratory problems and heart, eye, and skin diseases.

The measures in 2013 have been switched from the focus on “burning control” to “no burning.” The Ministry of Natural Resources and Environment has set the period from 21 January to 10 April 2013 to prohibit burning in all forest areas. Campaigns have also been launched to encourage local people to stop all kinds of burning in the forest. Thailand will seek cooperation from Laos and Myanmar in controlling forest fires along border areas.

The Department of Land Development is launching a campaign for agricultural leftovers to be plowed under, instead of being burned. The campaign is a new measure to combat the smoke haze problem, while increasing soil fertility. Efforts will be made to provide farmers with knowledge about how to turn weed into biogas and electricity, so that it will not be burned and create haze pollution.

Apart from hot dry weather, the burning of solid waste and agricultural materials in open areas has been cited as a major cause of forest fires. Another cause involves the slash-and-burn farming technique employed by farmers to clear land in forested areas (click here for more information).
