Palm oil & air pollution
Smoke pollution from forest firesThe burning of forests to clear land for oil palm plantations in Indonesia and, to some extent, Malaysia has been cited as the major cause of the air pollution that affected many areas of Southeast Asia in recent years including Singapore and other cities.
Once started, many of the fires in peat forests burned uncontrolled both underground and above ground for months.
Diverse impactsThe haze produced by the fires posed serious health problems to plantations workers and people throughout Southeast Asia.
Such haze can also reduce the productivity of oil palm trees and reduce the activity of pollinating weevils.
In addition to air pollution, burning of forests releases CO2 to the atmosphere and so contributes to climate change.
Still common practiceWhile the practice of burning has been outlawed in Malaysia and Indonesia, it is still occuring – as well as in other parts of the world where plantation establishment is now occurring.
