ABSTRACT

Coastal areas around the world are threatened by an accelerated sea level rise (SLR), storm surges and coastal flooding related to climate change. These threats, together with the land use pattern of coastal areas, could create a dangerous mix for coastal communities and could result in major socio-economic and environmental consequences. Apart from human settlements, seaports are likely to be most vulnerable to climate change because they are located at areas exposed to SLR and storm surges or at mouths of rivers susceptible to flooding. To remain efficient and resilient, seaports must anticipate the impacts of climate change and proactively prepare for SLR, increased flooding, and more frequent extreme storm events. This paper presents the analytical and empirical aspects of an integrated vulnerability index (VI) for small raft harbours based on the methodology of the IPCC for coastal vulnerability assessment. Six corresponding steps are adopted to assess the fishing ports VI (VIP-F) considering geophysical and socio-economic parameters. The proposed index is applied to 47 fishing boats and small commercial harbours of Lesvos, Greece. The proposed methodology can be adapted for assessing the vulnerability of major ports.

摘要

世界各地的沿海地区都受到海平面上升（SLR）加速，风暴潮和与气候变化有关的沿海洪水的威胁。这些威胁，加上沿海地区的土地使用方式，可能对沿海社区造成危险的混合，并可能导致重大的社会经济和环境后果。除了人类住区外，海港可能最容易受到气候变化的影响，因为它们位于遭受单反和暴风雨袭击的地区或易受洪水泛滥的河口。为了保持效率和弹性，海港必须预见气候变化的影响，并积极为SLR，洪水泛滥和更频繁的极端风暴事件做好准备。本文介绍了基于IPCC沿海脆弱性评估方法的小型筏港综合脆弱性指数（VI）的分析和经验方面。考虑到地球物理和社会经济参数，采用了六个相应步骤来评估第六渔港（VIP-F）。拟议的指数适用于希腊莱斯沃斯岛的47艘渔船和小型商业港口。所提出的方法可以适用于评估主要港口的脆弱性。
