Integrated coastal vulnerability assessment model for Bali Island

Abstract

Vulnerability is defined as the extent to which a population or an ecosystem is liable to be affected by a hazard event . A Numerical assessment measures the probability of physical changes based on analysis of physical and human-interference variables. The approach model attempts to combine susceptibility with the ability of the system to adapt and to cope with these problems. Vulnerability indexes provide a measurement of vulnerability potential affected by natural and human induced sea level rise that likewise may contribute to or trigger an increasingly vulnerability. The vulnerability assessment method integrates two variables, namely physical and human influence variables that include also the influence of culture and traditional wisdom is expected to be a more integrated assessment model for the estimation of coast vulnerability. By including human induced activity into the vulnerability assessment model, more objective vulnerability indexes to improve management in coping with affected sea level rise, and preparation of strategy, anticipation and adaptation to climate change will be resulted. The application of the coastal vulnerability assessment model in Bali showed that both physical and human-interference variables had affected the coastal vulnerability of the island.
