Modelling the economic vulnerability of households in the Phang-Nga Province (Thailand) to natural disasters

The 2004 tsunami devastated large areas in the southern part of Thailand. This paper takes a particular look at the circumstances of vulnerability and the process of recovery in the area of Khao Lak and its surrounding villages, which constitute a booming tourist hotspot at the centre of a region that is still dominated by agriculture. A quantitative vulnerability model was developed, integrating a quantitative household survey and remote sensing data. This model describes and specifies the circumstances of vulnerability and the factors leading to a recovery of the area. Indirect effects on the livelihood of households in particular, such as the disruption of infrastructure or the loss of income, show a negative effect on the recovery time. External help received by the households even shows an extending influence on the duration of their recovery period.
