Land clearing with fires had been blamed for most big fires in a number of regions in Sumatra including South Sumatra.
Deputy Governor of South Sumatra Ishak Mekki said strict law enforcement is necessary to create greater awareness of potential damage caused by fires to the environment.
"Firm action would be taken by cancelling the license," Ishak said here.
He said plantations companies are not only disallowed using fires but are also responsible for preventing fires in their lands.
Meanwhile South Sumatra police said they are still processing a number of forest fire cases in 2015 and 2016.
South Sumatra police spokesman Sr.Comr R Djarod Padakova said in 2016, there were two new forest fire cases with dossiers already handed over to the prosecution office in addition to carryover cases from 2015.
Police also are busy in socializing the ban on using fires to clear farmlands in district areas as human errors caused around 90 percent of the forest fires in the region, Djarod said.
"Human approaches have succeeded in reducing cases of forest fires this year compared with previous years," he said.
