Late last month, Indonesia saw the return of its infamous forest fires that occur each year producing toxic, choking smog in the form of haze as the rainy season trails off. The fires this time have broken out in the four provinces of South Sumatra, Riau, West Kalimantan and Central Kalimantan. Twenty-three of the 90 hotspots recorded across the country were in West Kalimantan, where thick smoke blanketed the provincial capital Pontianak and disrupted flights.
