TRANSBOUNDARY haze affecting Malaysia has been an ongoing problem for decades, and is mainly caused by forest fires due
to agricultural techniques known as “slash-and-burn” from across the border (whether land, i.e. Kalimantan or
cross-straits, e.g. Riau). The root cause of this is the burning of peat lands for cultivation, which takes place especially during the drought season. This is when peat soil becomes flammable and fire spreads easily.
