The study aimed to assess the vulnerability due to climate change (CC) of rural fresh water and sanitation (RFWS) – an interest issue because of its important role in life as well as sensitivity to CC effects; a case study in coastal area in Ho Chi Minh city, Vietnam (Can Gio district). By index method, applied for the first time in RFWS field, vulnerability (V) was evaluated through 51 indicators. They include 20, 12, and 19 indicators with their weights refecting exposure level (E), sensitivity (S), and adaptive capacity (AC) of the system, respectively. The results showed the positive trend of AC and S by the time while E has insignificantly changed in the context of CC; subsequently, the V index tends to decrease toward 2025 (at medium-low level). The causes and defective chains of each component of E, S, and AC were then analyzed and identified (5 E indicators, 9 S indicators, and 13 AC indicators). Therefore, the priority to manage should be improving AC, followed by reducing S and E.
