The Indonesian Environmental Affairs and Forestry Ministry recorded 2,070 hotspots, with a confidence rate at over 80 percent, during the January-July 2019 period, based on monitoring of the Terra and Aqua Modis satellites.
"The number of hotspots was higher than that in 2018 but lower than that recorded in 2015," Eva Famurianty, head of the Early Warning and Detection Section of the Climate Change Mitigation Directorate General of the ministry, remarked here on Wednesday.
In 2018, the number of hotspots across Indonesia reached 1,338, up from 362 in 2017.
The number of hotspots in Riau Province during the January-July period surged by 406 hotspots compared to that during the same period in 2018, while the figure was up by 43 hotspots in Central Kalimantan, and in West Kalimantan, the figure went down by 159.
This year's El Nino is relatively weak, but the number of days when no rains were received is longer, notably between 30 and 120 days. Several regions have also experienced rainless days for over 120 days.
During the same period, the Landsat satellite image indicated that a total of 135,747 hectares of forest areas were razed by fires. The indicative gutted forest areas comprised 31,002 hectares of peatland areas and 104,746 hectares of mineral land areas.
The ministry's Director of Forest Fire Mitigation Raffles B. Panjaitan remarked that of the eight provinces prone to forest fires, six have declared an emergency status for forest fire.
