Usability of existing global and national data for flood related vulnerability assessment in Indonesia.

Public climatic data are rapidly growing in volume and complexity at global and national scales but these data remain underutilized for vulnerability assessment. We aim to explore how flood records from Dartmouth Flood Observatory, a global flood monitoring database, can be linked with a national disaster database maintained by the Indonesian National Board for Disaster Management, to aid local vulnerability assessment in Indonesia. We focused on physical damage to structures and agricultural crops from flooding and examined spatiotemporal patterns of a vulnerability metric derived from principal component analysis.
