Abstract

Assessing the vulnerability for some economic sectors of Binh Dinh province plays a very important role. The study has applied the vulnerability method according to Iyengar and Sudarshan to assess vulnerability for 03 different sectors: 1) Agriculture, forestry and fisheries; 2) Industry and construction and 3) Service. Calculation results of vulnerability classification for different sector groups according to the E, S, AC, and Vi indicators are used to develop a hierarchy of vulnerability classification for different sector groups. The calculation results indicate that only Phu My district has a high vulnerability index for agriculture, forestry and fisheries with the value of Vi = 0.6; For the service sector, only Quy Nhon City has a high vulnerability index with the value of Vi = 0.63. The vulnerability index calculated for sector groups for the remaining regions is low to moderate. The result of the vulnerability classification maps due to sea level rise will help planners and managers make plans, plans and solutions to mitigate risks caused by natural disasters.

Summary

Introduction

There is a multitude of definitions and interpretations of the term vulnerability [1]. Vulnerability and adaptive capacity are multidimensional, complex and no directly observed phenomena [7] making their evaluation difficult; studies have addressed this problem using different approaches They have focused, for example, on the vulnerability to a particular stressor, such as rising sea levels [8] [9] [10] as well as on assessing the impacts of climate change [11] [12] [13] [14]. Sea level rise is one of the most serious threats of climate change that is currently impacting coastal areas Potential impacts cover both socio-economic and biogeophysical sectors as the results of increasing flood frequency, inundation, coastal erosion, rising of water table, and saltwater intrusion [15]. The actual degree of damages from sea level rise to a specific coast depends on the adaptability of the affected socio-economic and ecological systems of that coast, as well as its potential for harm by a hazardous event [2]
