Dry season already started in Indonesia and expected to end on September. Last year’s fires were the worst since 2015 due to dry weather, with some 1.6 million hectares of land, mostly on Sumatra and Borneo islands, razed by the out-of-control blazes. And the fires sent a toxic haze across Southeast Asia that forced school closures and aggravated concerns about.
Indonesia has started cloud seeding to induce rain as the archipelago moves to head off annual forest fires blamed for blanketing swathes of Southeast Asia in toxic haze.
Authorities deployed tens of thousands of personnel and water-bombing aircraft to tackle the fires, which are intentionally set to clear land for agriculture — including on palm oil and pulp plantations.
Over the past two weeks, Indonesia has started cloud seeding — a technique that uses chemicals to induce rain — in hotspot Riau province on Sumatra, with plans to roll it out in other parts of the island and in Borneo. The operations were to last throughout the dry season.
“We’re taking this step before the forest fires start,” said Tri Handoko Seto at the government-backed Agency for the Assessment and Application of Technology (BPPT).
The initial focus would be on swampy, carbon-rich peatlands which become highly flammable when they are drained of water to grow crops, he added.
“According to our predictions, the dry season this year will not be as bad as it was last year… but we never know” for sure, Seto said.
During the Covid-19 pandemic, personnel that involved in the assessment must adhere to the Standard Operating Procedures (SOP) which include wearing PPE and safe-distancing.
“If things escalate and we see haze like last year, we might use another technique. Let’s pray it won’t come to that,” he added.
