Deforestation Fuels Floods in Aceh and Sumatra

 Aceh – 10 December 2024

Recent floods that inundated large parts of Aceh and several regions across Sumatra have once again raised concerns over deforestation in upstream areas. After the floodwaters receded, piles of wood and cut tree trunks were found scattered almost everywhere  along riverbanks, on roads, inside residential areas, and near evacuation centers.

Residents described the aftermath of the floods as alarming. Large logs, broken branches, and timber debris were left behind across villages, blocking access roads and damaging homes. During the peak of flooding, strong currents reportedly carried the wood downstream, worsening the overflow and increasing destruction in low-lying areas.

Photos and videos shared by residents and volunteers showed tree trunks with visible cut marks, indicating that the trees were not naturally fallen but had been felled before being swept away by floodwaters. Environmental observers said this pattern is commonly linked to forest clearing activities in watershed areas.

“After the water went down, wood was everywhere,” residents said, expressing concern that upstream forest loss had intensified the disaster. Environmental groups explained that without sufficient forest cover, rainwater flows directly into rivers instead of being absorbed by the soil, causing rivers to rise more rapidly during heavy rainfall.

Several affected regions have experienced ongoing land conversion for plantations and other development projects. While some activities are carried out under legal permits, activists argue that weak monitoring has allowed excessive forest clearing to continue.

Local authorities acknowledged the presence of widespread wood debris after the floods and stated that investigations are ongoing to determine the source of the logging. Officials said legal action would be taken if illegal activities are confirmed.

As cleanup efforts continue, residents fear that flooding will remain a recurring threat unless upstream forest conditions are addressed. Calls for stronger forest protection and restoration have grown louder following the discovery of extensive logging debris.

The floods in Aceh and Sumatra have left more than muddy streets behind they have left clear physical evidence of how forest loss upstream can translate into disaster downstream.
