Coastal Vulnerability Assessment of Bali Province, Indonesia Using Remote Sensing and GIS Approaches

Coastal zones are considered to be highly vulnerable the effects of climate change, such as erosion, flooding, and storms, including sea level rise (SLR). The rising levels endanger several nations, Indonesia, it potentially affects coastal population natural environment. Quantification is needed determine degree vulnerability experienced by a coast since measuring fundamental phase towards effective risk reduction. Therefore, main objective this research identify how zone Bali Province develop Vulnerability Index (CVI) areas exposed sea-level on regional scales using remote sensing Geographic Information System (GIS) approaches. This study was conducted in Province, which has beach length ~640 km, six parameters were creation measure CVI: geomorphology, shoreline change rate, elevation, tidal range, significant wave height. different assigned ranks ranging from 1 5, with indicating lowest 5 highest vulnerabilities. revealed that about 138 km (22%) mapped classified being at very high 164 (26%) vulnerability. Of remaining shoreline, 168 169 moderate low vulnerability, respectively. outcomes can provide an updated map valuable information for coast, aimed increasing awareness among decision-makers related stakeholders development mitigation adaptation strategies. Additionally, result may utilized basic data build implement appropriate management.
