Catastrophic Flooding in Sumatra: Deforestation Blamed as Death Toll Rises

From November 21-23, 2025, Tropical Cyclone Senyar brought extreme rainfall, causing the Parlampungan River to overflow and submerge villages in the Mandailing Natal Regency under as much as two meters of water. The resulting floods and landslides washed away roads, bridges, and telecommunications, isolating communities and hindering rescue efforts. Environmental groups highlight the extensive deforestation in Sumatra, with Global Forest Watch reporting that Aceh, North Sumatra, and West Sumatra have lost 19,600 square kilometers of forest since 2000. This loss of primary forest has left the region dangerously exposed to natural disasters. President Prabowo Subianto has pledged policy reforms to prevent further deforestation, and investigations are underway to hold accountable companies involved in environmentally damaging practices. Relief efforts are ongoing, with local organizations and international aid groups providing assistance to the affected populations.
