JAKARTA: About a week after floods and landslides devastated three provinces in Indonesia’s Sumatra island, Rubama witnessed firsthand how the deluge left not only debris and rubble but also log after log of timber.

They were the first thing that she saw when she arrived in the Beutong Ateuh Banggalang district of Aceh, where at least two villages were wiped out by floodwaters.

“We saw these neatly cut logs moving down the river. Some were uprooted from the ground, but there are logs cut into specific sizes. This shows that the disaster in Aceh, in Sumatra, it’s all linked to illegal forestry practices,” Rubama, empowerment manager at Aceh-based environmental organization HAKA, told Arab News.

Monsoon rains exacerbated by a rare tropical storm caused flash floods and triggered landslides across Aceh, North Sumatra, and West Sumatra in late November, killing 969 people and injuring more than 5,000 as of Wednesday, as search efforts continue for 252 others who remain missing.

In the worst-hit areas, residents were cut off from power and communication for days, as floodwater destroyed bridges and torrents of mud from landslides blocked roads, hampering rescue efforts and aid delivery to isolated villages.
