The study aimed to partition vulnerabilities caused by climate change in suburban districts of Ho Chi Minh City by integrating the use of AHP and GIS. The subjects used data collected from different departments, from surveys in the study area, and consulted with experts in the field of research to assess the weight of factors: Exposure, sensitivity and adaptability. After overlapping component maps, the results showed that the high vulnerability to climate change in five suburban districts of Ho Chi Minh City by 2025 was dominated by Binh Chanh, Nha Be and Hoc. Area of 35,865.57 ha (accounting for 22.84%). The low and medium damage was concentrated in Cu Chi and Can Gio (the respective area was 36,354.33 ha, equivalent to 23.16% and 84,762.27 ha, equivalent to 54%). In addition, the study proposed solutions to increase adaptation and mitigation of the impacts of climate change on the lives of people in the affected area.
