Agricultural areas in the coastal provinces in the Mekong Delta have been affected by climate change. The objectives of this study were to: (i) determine the influence levels of six hydrological factors including salinity, salinity time, flooding, flooding time, drought and rainfall on agricultural production; and (ii) evaluate and zone the agricultural areas where were affected by climate change. The research interviewed 34 experts and 210 farmers living in coastal provinces in the Mekong

Mapinfo sotfware was used to zone and establish the zoning map of agricultural production areas which were affected by climate change. The results of study showed that the natural factors level could be assessed using multicritical evaluation method. The rice, upland crops and aquaculture systems were affected by salinity intrusion and flooding. Models of fruits and sugarcane were affected by flooding. Agricultural production zones were affected by climate change at different levels (low, moderate, and high) occupied 66%, 22% and 12%, respectively.
