Climate change rate has sped up due to intensified anthropogenic activity and mainly give impact on coastal erosion. In Southeast Asia, an increase of 20 million people in coastal has accentuated the vulnerability to human infrastructure. In Malaysia, littoral erosion due to inclement seasonal monsoons can critically affect the coastal population and the country is lacking practical plans to attenuate coastal erosion. Therefore, a systematic coastal vulnerability assessment that covers ten physical and five socio-economic parameters has been conducted at sixteen districts of four states on east coast of Peninsular Malaysia. It is to highlight the most vulnerable districts toward the catastrophic natural hazards event. Multivariate statistical analyses have facilitated realistic and meaningful interpretations for optimal coastal zone planning. The finding shows the socio-economic parameter is extremely relevant in all states except in southern Terengganu because it faces a direct impact of monsoon waves. Gender was found to be the most dominant coastal vulnerability for two states: Kelantan and Terengganu (North) due to the abundance of women involved in the coastal entrepreneur. Besides, agriculture indicates a primary concern in the district of Johor. The results were categorized from very low to very high and they reveal that the northern states of the east coast of Peninsular Malaysia show very high to high vulnerability relative to the southern states, which illustrate moderate to very low vulnerability. The authorities could utilize the findings of this study to forecast potential shoreline recession and establish adaptation measures to their ultimate coastal erosion mitigation plan.
