Methane emissions from flooded rice paddies contribute to global warming just as coal-fired power plants, automobile exhausts and other sources do with the carbon dioxide they spew into the atmosphere.
In fact, the report from the Intergovernmental Panel on Climate Change meeting this week in Bangkok concludes that rice production was a main cause of rising methane emissions in the 20th century. It calls for better controls.
"There is no other crop that is emitting such a large amount of greenhouse gases," said Reiner Wassmann, a climate change specialist at the International Rice Research Institute in the Philippines.
