Weeks after Cyclone Senyar made landfall in northern Sumatra, Indonesia, the province of Aceh continues to struggle. The cyclone passed through the Strait of Malacca in late November, bringing heavy rains and causing widespread flooding in parts of Indonesia, Malaysia and Thailand. More than 500 people were killed and 250,000 people displaced in Aceh alone.

The cyclone’s unusually high death toll and catastrophic impacts have been attributed to a range of factors, including warming ocean temperatures due to climate change, deforestation and other environmental changes, Aceh’s unique geographical and topographical setting and how rarely cyclones occur near the equator.

What’s missing from the discussion is the root cause of why Aceh was ill-prepared for the hazard. Like many other regions in the Global South, Aceh’s vulnerability can be traced back to colonialism, which created an inequitable distribution of power, wealth and resources. Post-colonial development continues to reinforce it.

The impact of Cyclone Senyar has drawn parallels to the 2004 Aceh tsunami that devastated the province and surrounding areas. Since then, disaster preparedness in Aceh has come a long way. Yet the aftermath of Senyar suggests that disaster preparedness efforts have not tackled Aceh’s underlying vulnerabilities.
