Abstract

Climate risk and vulnerability assessments were undertaken in the Caribbean for national ministries, with funding from the Caribbean Development Bank. The studies evaluated the impacts of climate-related natural hazards on road transport infrastructure and identified measures to strengthen resilience. Geographic information systems were used to map infrastructure assets and structural condition, and climate-related variables were then integrated to model current and future hazard scenarios. The datasets were analysed to identify hotspot areas of the road network where adaptation interventions were proposed, and to prioritise climate-resilient investments. The assessment findings helped decision makers to understand system resilience, adaptive capacity and how critical risk hotspot areas could be mitigated. Improved road infrastructure design and a more proactive approach to road and structure maintenance will help increase the resilience of the road networks by reducing vulnerability to hazards and minimising the impact of climate change.

利用气候风险和脆弱性评估确定加勒比地区道路投资的优先次序

在加勒比开发银行的资助下，在加勒比地区为国家部委进行了气候风险和脆弱性评估。这些研究评估了与气候有关的自然灾害对道路运输基础设施的影响，并确定了加强抵御能力的措施。地理信息系统用于绘制基础设施资产和结构状况，然后将气候相关变量整合到当前和未来的灾害情景模型中。对这些数据集进行了分析，以确定提出适应性干预措施的道路网络热点区域，并确定气候适应型投资的优先顺序。评估结果有助于决策者了解系统弹性、适应能力以及如何减轻关键风险热点区域。改进道路基础设施设计，采取更积极主动的道路和结构维护方法，将有助于通过减少对灾害的脆弱性和最大限度地减少气候变化的影响，提高道路网络的复原力。

期刊介绍： Engineering Sustainability provides a forum for sharing the latest thinking from research and practice, and increasingly is presenting the ''how to'' of engineering a resilient future. The journal features refereed papers and shorter articles relating to the pursuit and implementation of sustainability principles through engineering planning, design and application. The tensions between and integration of social, economic and environmental considerations within such schemes are of particular relevance. Methodologies for assessing sustainability, policy issues, education and corporate responsibility will also be included. The aims will be met primarily by providing papers and briefing notes (including case histories and best practice guidance) of use to decision-makers, practitioners, researchers and students.
