Saltwater intrusion, which is a natural process, is strongly influenced by climate change, and almost negatively affects the lives and livelihoods of communities. This work aims at assessing changes in saltwater intrusion in main rivers located in Dong Nai province. The results indicated that Long Thanh and Nhon Trach districts have been affected by saltwater intrusion with the highest salinity concentrations of about 26-28 ‰. The salinity level during the dry season is higher than that in the

Besides, adaptive capacity (AC) to saltwater intrusion in Bien Hoa city, Long Thanh and Nhon Trach districts was surveyed and assessed by the AC indices. By assessing AC of local government and communities against 19 criteria, Nhon Trach district showed its high AC meanwhile AC of Long Thanh and other districts were moderate and low, respectively. This research also indicates limitations of each locality, an important basis for proposing solutions to improve AC to saltwater intrusion for the communities.
