ABSTRACT: 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.
