Widespread Fires, Smoky Skies Across Southeast Asia
acquired March 5, 2010
The skies over Burma (Myanmar), Thailand, Laos, and Vietnam were extremely smoky on March 5, 2010, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite passed overhead and captured this image. Hundreds of active fires were detected by the sensor; locations are outlined in red.
Many of the fires, particularly in the permanently cultivated lowland areas, are not particularly smoky. This is often a sign that the fires are burning only small amounts of vegetation, such as crop residue or dry grass in pasture. Other fires are generating thick smoke plumes which spread east. These may be accidental fires that spread from agricultural areas into forest areas, or they may be intentional forest-clearing fires.
Widespread fires are a common occurrence in Southeast Asia during the late dry season, and while they are not necessarily immediately hazardous, they can have a significant impact on regional air quality and public health, greenhouse gas emissions, and natural resources.

Taking the green plunge
Organic rice farmers enjoy double benefits
May 20, 2008
By Peter Janssen, dpa
Rice prices have more than doubled, so paddy in the field means money in the bank or debts paid off. Thai farmers growing organic rice have even more to smile about.
Although organic rice farming is still miniscule in Thailand, where most farmers remain attached to their chemical fertilisers and industrial pesticides, those who have taken the green plunge are reaping double rewards this year.
"If you use chemical fertiliser you have to buy from the market and now the price of fertiliser is very high because it is linked to oil prices," said Upin Khasana, an organic rice farmer in Sanam Chai Ket district of Chachoengsao province, 60 kilometres east of Bangkok.
Upin belongs to a 15-family co-op of farmers who decided to switch to organic rice growing seven years ago, with technical input from Green Net, a non-governmental organisation that promotes organic farming in Thailand and helps farmers sell their crops on the domestic market and abroad.
The Chachoengsao co-op uses only natural fertiliser - cow and goat droppings - and no chemical pesticides. In return, Green Net buys their rice at a premium price, usually a little above the market's, and handles the certification process under the International Federation of Organic Agriculture Movements (IFOAM), selling under the Green Net brand name.
After 14 years in the business, Green Net is only producing about 2,000 tons a year of organic rice, supplied by cooperatives in Yasothon, Chiang Mai, Uttaradit, Loei, Khon Khen and Chachoengsao provinces.
"We started out just selling locally, but now we export about 85 per cent," said Vitoon Panyakul, director of the Green Net.
Green Net's only competitor in the organic rice trade is the Capital Rice Company, one of Thailand's leading rice exporters.
Capital Rice started an organic rice farm project in Chiang Rai province in 1991, at the request of Italy's Riseria Monferrato S.p.A., a major rice distributor in Europe.
Last year, Capital Rice exported about 1,000 tons of organic rice under its Great Harvest brand, mainly to Europe.
"If you compare that to Capital Rice's total exports, it is very small, less than 1 per cent," said Wanlop Pichpongsa, deputy managing director of the company.
Thailand's total rice exports last year amounted to 9.55 million tons, earning the country 3.6 billion dollars. This year's rice exports are estimated to reach 8.75 million tons, earning as much as 4.7 billion dollars, winning farmers and exporters a bonanza from higher commodity prices, ramped up by high oil prices and artificial shortages caused by export bans in India and Vietnam.
If anything, the doubling of rice prices this year is probably bad news for organic rice traders such as Green Net and Capital Rice, since higher prices will encourage farmers to try to produce more paddy by using more chemical fertilisers.
"In a way it is okay, because we will see that those who remain with us are really committed to the organic cause," said Green Net's Vitoon. "So it's a way to shake things up a bit and see who is in it just for the money and who is committed."
Capital Rice has put its organic rice expansion plans on hold, also because of uncertainty about farmers' "commitment."
"The character of a community has to be suitable for organic farming," noted Wanlop. "Not every community is suitable. For instance, the rice growers in the central plains can grow rice two- three times a year by using chemicals and pesticides, so they are not interested."
But for the organic rice growers of Sanam Chai Khet in Chanchoengsao, staying committed to the organic cause is more about choosing a lifestyle.
"We do it for our lives more than for the money," said Nutchainat Keowuwee, a member of the Chachoengsao Green Net co-op. "My husband worked with chemical fertiliser for a long time and he became sick. His health was no good. That's one reason I switched to organic."
In Sanam Chai Khet, as in most rice growing villages in Thailand, the farmers keep most of their rice harvest for their own consumption through the year, selling only a portion of it to Green Net for sale on the domestic or export markets.
"The price we get for our rice is about the same as the market price, but what we get is better health," said Uenfah Chamkhet, another co-op member. "We are saving money on medical bills."

FDA warns of cheap and fashionable teeth braces
The Food and Drug Administration has warned that some cheap but fashionable teeth braces popular among youngsters are contaminated with lead, selenium, chromium and arsenic.
If the dangerous substances accumulate in the body, they can cause kidney failure and even death, says Deputy Public Health Minister Chaovarat Chanweerakul. He warns that some braces available outside dental clinics and hospitals are made with substandard materials and can cause an accumulation of toxins.
— Orthodontic braces are such a status symbol in Thailand that some young people who don't need them, or whose families can't afford the real thing, buy and proudly wear these potentially dangerous fakes —
