Assessing coastal vulnerabilities to climate change impacts in Thai Thuy district, Thai Binh province
Keywords:
Adaptation, Climate change,, coastal areas, index, mitigation,, vulnerabilityAbstract
Based on coastal topographical features and natural conditions, 3 groups
of indices were selected to assess the coastal vulnerability, including
(i) topographical and geomorphological indices; (ii) ecological and
environmental indices; and (iii) socio-economic indices. As results
showed that the total length of coastal shorelines is 21.3km, including
15.2km coastline with low level of vulnerability; 3.2km with average level
of vulnerability; 2km high with level of vulnerability; and 0.8km of
coastline with a very high level of vulnerability. Areas with the greatest
vulnerability to climate change is the area of Thai Thuong commune,
where are adjacent to the Diem Diem town and Diem Ho river side. These
areas are identified with sparse vegetation and a high erosion, and
relatively weak coastal protection structures. In addition, the Diem Diem
town also is classified as the high degree of vulnerability, beca use the area
is known as highly populated areas with intensive business and trading
activities and with thin mangrove width. Moreover, the dykes in these
areas are being degraded gradually in where the adjacent estuary meets the
sea. Therefore, this area will be the highly vulnerable to climate change.
In contrast, Thuy Truong, Thuy Xuan and Thuy Hai have the lowest level
of vulnerability due to a large and thick mangrove width and relatively
uniform, large deposition rate, firm and safe dyke systems; and local
people are living far away from the sea dike these areas.
