Integration of disaster risk reductionand climate change adaptation in Aceh: Progress and challenges after 20 Years of Indian Ocean Tsunamis

The Indian Ocean Tsunami (IOT) of 2004, which tragically claimed 168,000 lives and displaced about half a million people in the Aceh region of Indonesia, established Aceh's reputation as one of the most geologically volatile areas in Southeast Asia. Unfortunately, the 2004 IOT also altered some geomorphological changes, particularly land subsidence in the coastal areas of South, Southwest, and West Aceh, making these regions more susceptible to coastal floods and inundation over the last 20 years. The 2004 tsunamigenic earthquakes had been compounded by hydroclimatic hazards (and required to reduce risk beyond geological disasters) that continued to cause loss and damage, compromise communities' well-being, and reproduce vulnerabilities. This article examines the progress and challenges for integrating disaster risk reduction (DRR) and climate change adaptation (CCA) in Aceh, with a focus on the capital city, Banda Aceh using in-depth stakeholder interviews and document reviews. Anticipating gaps in meeting Sendai Framework 2030 target, as also observed elsewhere in Indonesia and Southeast Asia, the findings suggest various key challenges for the integration, including (1) fragmented DRR and CCA policies leading shaped the gap in coordination and collaboration among actors; (2) nurturing political commitment remains a challenge at local level; (3) lack of fiscal capacity and lack of earmarked allocation hampers the potential integration; (4) and deficits in community participation delayed adaptation and integration. The study offers recommendations for policy insights and consideration.
