Toxic fumes from the Indonesian fires that have spread a choking haze across Southeast Asia may be doing more harm to human and plant health than officials have indicated, scientists measuring the pollution say.
Farmers are expecting a poor harvest because plants have too little sunlight for normal photosynthesis, while government figures of half a million sickened by the smoke are only the "tip of the iceberg", said Louis Verchot, a scientist with the Center for International Forestry Research (CIFOR).
Meanwhile, the fires are converting carbon stored in burning peatlands into greenhouse gases, contributing to climate change.
"When the sun goes up, the whole world is yellow. On the worst day, the visibility was less than 100 metres (328 ft)," said Verchot, who led a workshop on the crisis in Central Kalimantan province last month with about 20 scientists from Indonesia, the United States and Britain.
While taking measurements on a burning 5,000-hectare (12,000-acre) plot, the scientists - equipped with gas masks and a drone - trod carefully across the ash-covered peatland to avoid calf-deep holes, hot from the smouldering underground. Full story...
