Using Geography Information System (GIS) tools and remote sensing data in assessing the level of vulnerability of agricultural production activities in the coastal area has become more efficient in the recent years. This research has identified the sensitivity index (S) (including the traffic access index; the impact of residential areas; the impacts of industrial zones; the community dependence level), exposure index (E) (the sea level rises to 2100; the temperature change to 2100), the adaptable capacity index (AC) (slope; morphology), thereby synthesizing the vulnerability index (V). Based on the indexes to calculate vulnerability, the high to very high vulnerability area is 37,081.44 ha, accounting for 68.09%; the average vulnerability level is 15,286.49 ha, accounting for 28.07%; the low to very low vulnerability level with an area is 2087.82 ha, accounting for 3.84% of the total area. With a high and very high vulnerability accounting for 68.09%, there will be great influences on the lives of resident in the area, especially agricultural production.

Climate change has been severely affected the lives of people in coastal areas of Vietnam, particularly in the poor communes in the Central region, namely Quang Binh, Quang Tri, and Thua Thien Hue. This report focuses on analyzing and assessing the vulnerability caused by climate change in the extremely poor communes in Quang Binh, Quang Tri, and Thua Thien Hue province, including five levels: Very low, low, medium, high, very high. Through the IPCC vulnerability assessment method, which includes three components: exposure, sensitivity, and adaptive capacity, the results in the study area showed that the medium level accounted for 19.64%, the high level accounted for 30.48%, and the very high level made up 37.35% of the area.
