Exploring Dynamics and Effective Strategies for Tidal Flood Risk Reduction in Indonesia's Coastal Cities

Indonesia’s coastal regions have distinct charateristics. However, nearly all of these coastal regions are vulnerable to tidal floods. The purpose of this study is to determine the features of coastal regions in Indonesia that have been damaged by tidal floods, as well as the actions implemented to mitigate disaster risk. Thus study takes a qualitiative method with explanatory analysis. The Island Spatial Planning is used to classify Indonesia’s archipelagic regions.An urban area vulnerable to tidal flood was selected from each archipelagic region. The characteristics of coastal regions affected by tidal flood were identified by the tidal flood characteristics, coastal physiography. and socio-economic conditions of the affected areas. The tidal-flood Disaster Risk Reduction (DRR) strategies devised by the government and local communities were discussed. The results showed that tidal floods mostly occurred on the gentle-slope coast. Meanwhile, the measures taken for tidal flood DRR have not been properly implemented. The tidal flood-prone areas identification was only found in some areas. On the other hand, local communities have shown many roles in various non-profit actions related to tidal flood DRR. A stronger commitment to implement tidal flood DRR is needed from the government and related stakeholders.
