At the end of November 2025, floods and landslides hit dozens of districts/cities spread across three provinces of Sumatra Island, namely Aceh, North Sumatra, and West Sumatra.

This disaster resulted in the deaths of around 1,200 people, 138 missing, and about 300,000 damaged houses.

The Pelopor Pilihan Tujuhbelas Foundation (PP17) then surveyed the perceptions of Indonesian citizens about the triggers of the Sumatra disaster.

The results showed that the majority of respondents believed the disaster was triggered by deforestation.

There were also quite a few who believed the Sumatra disaster was triggered by illegal logging, land conversion for oil palm plantations, and land conversion for mining.

Here are the details of the triggers of the flood and landslide disasters in Sumatra according to Indonesians surveyed by PP17:

Deforestation: 49% of respondents
Illegal logging: 47%
Land conversion for oil palm plantations: 38%
Land conversion for mining: 36%
Heavy rainfall: 24%
Lax policies: 24%
Accumulated waste: 16%
Tropical cyclones: 16%
Climate change: 12%
Don't know: 1%

PP17 conducted this survey from January 16-19, 2026, using the computer-assisted self interviewing (CASI) method, involving 400 respondents aged between 17-44 years from all over Indonesia.
