This study aimed to evaluate the adaptive capacity (AC) to saltwater intrusion (SI) in Dong Nai province up to 2030 via 20 indicators. The research scope included 57 wards in Bien Hoa city, Long Thanh, and Nhon Trach districts where have been facing the SI. Results showed that in 2014, nearly 90 % of investigated wards have AC indices in the range of medium-low level, distributed in Bien Hoa (30), Long Thanh (15), and Nhon Trach (6). Forecasts to 2020 and 2030, the local AC indices to saltwater intrusion are increased: the mentioned number of 90 % is gone down to about 88 % and 60 % in 2020 and 2030, respectively. Indicators need taken into concern to improve the local AC include: financial (budget, GDP), policy (support for people to cope with SI and climate change), agriculture (salt-tolerant seeds), aquaculture (brackish and saline water aquaculture), irrigation work (irrigation, SI prevention system), water storage, health, and education. Overall, in the period of 2014–2030, the AC of the investigated area has increased over the years, but most at the medium – low level. This is the challenge for governments and communities in responding to SI in the context of climate change.
