Climate Change Vulnerability Index

Areas that are more vulnerable to climate change are ones where people, infrastructure, and/or ecological resources are more likely to experience harm as temperatures rise, floods worsen, and high winds increase. Vulnerability is a complex concept and encompasses a variety of elements including physical exposure, sensitivity or susceptibility to harm, and lack of capacity to cope and adapt. Understanding vulnerability helps us to make decisions about resource allocation, policy development, and project prioritization, siting, and design. View a Climate Change Vulnerability Index Fact Sheet and the following tools to better understand climate vulnerability in New Haven and Fairfield Counties.

Climate Change Vulnerability Index Viewer

The CCVI combines built, social, and ecological factors to identify areas that are vulnerable to flooding, wind, and heat related impacts of climate change.  This mapping tool can be used to view vulnerability at both a regional scale and at specific sites to see how factors are contributing. To learn more about the design and use of this tool, watch a recent March 23 webinar. This mapping tool will eventually be embedded into a Story Map to guide users through the content and results...check back on this web page to see updates!

CCVI Presentation

Winter, 2021 Workshop: The Resilient Connecticut team held their first regional workshops with four Council of Governments (COGs) in New Haven and Fairfield Counties. Workshops included two information sessions to learn about Change Vulnerability Index (CCVI) and Zones of Shared Risk (ZSR) findings. Each session was followed by small group collaboration exercises to discuss, refine, and to better understand these tools for future resilience planning efforts.
