SINGAPORE, June 24 (Reuters) – Singapore, Indonesia, Malaysia and Brunei face a high risk of severe haze this year due to hot and ​dry weather conditions, biofuel demand and ‌economic pressures, a research institute said Wednesday.

The Singapore Institute of International Affairs said it was the second time it had issued a red risk rating since launching its ‌Haze ​Outlook report in 2019. ⁠The previous red risk ⁠rating was in 2023.

Here are some details:

• August to September is the peak danger period for haze in the Southeast Asian region, driven ​by the El Niño and Indian Ocean Dipole weather phenomena, the report said.

• The ⁠return of El Niño is ⁠expected to create a longer and ​stronger dry season at a time when fire ​preparedness could be adversely affected by economic uncertainty ‌and cost pressures.

• The SIIA said rising costs of fertiliser and fuel as a result of the Iran war could lead to unsustainable ⁠activity such as the use of fire rather than machinery to clear land and dispose of waste.

• Land ⁠use could ‌also intensify as demand for ⁠biofuels rises due to energy supply disruptions.

• “This ​trend will ‌continue even if the US-Iran ​agreement holds, ⁠as countries now want energy independence,” said SIIA associate director Khor Yu-Leng.

• ASEAN cooperation and sustainable land management will be critical to reducing risks, the report said.
