BANJARMASIN, Indonesia — Siti Sarah slept in fits and starts through August as the fires broke out around her village and surrounding peatlands. One fire on Aug. 18 at first seemed a safe distance away, but in a heartbeat the flames were within 100 meters (330 feet) of her home in Pengayuan, a village in Indonesia’s South Kalimantan province.

“The fire seemed to leap up,” Siti told Mongabay Indonesia. “All of a sudden it was right there — it grew so fast.”

Cries for help echoed around the village as Siti joined the community’s firefighting press. “I also helped put out a fire,” she said. “By whacking it with a piece of wood.”
