Indonesia’s anti-graft commission said government agencies have agreed on a plan to combat corruption in the forestry industry that costs the state billions of dollars in lost revenue and is behind fires that pollute Southeast Asia. The plan leans heavily on technology to build an accurate picture of where illegal deforestation and conversion of peatland into farmland is occurring, using Landsat satellites, drones and LIDAR pulsed laser-based mapping.

According to the World Bank, forest fires in Indonesia last year caused the country at least $16 billion economic losses, which is equivalent to 1.9 percent of its GDP. The haze caused by the fire blanketed Singapore, parts of Indonesia, Malaysia and Thailand in September and October, which was cleared by the rainy season in early November. Many of the fires were set by smallholders and companies to clear land for agriculture, especially palm oil, which makes it difficult for Indonesian authorities to respond to the fires.

A study published in August in the journal Environmental Research Letters reveals that more than half of the fire emissions originate from outside timber and oil-palm concession boundaries. Several studies have shown a similar finding, which is that the dominant cause of fire in both Sumatra and Kalimantan is rural communities. Only targeting plantation companies as the government and NGOs are doing at the moment won’t work. The Indonesian fire and haze problem is complex, with multiple actors playing a role. To address the problem, the government should be more specific in its management, including law enforcement, localized approaches, taking the costs of development into consideration.
