As climate change escalates, coastal cities are facing a variety of risks. Climate-related risks are interconnected with the existing social, economic, and political challenges in cities, and have profound consequences for sustainability of coastal areas. The Climate and Ocean Risk Vulnerability Index (CORVI), developed by the Stimson Center and applied in coastal cities around the world in collaboration with the OPRI-SPF, is a tool which compares a diverse set of threats to produce detailed risk profiles. These risks are displayed across 10 categories, grouped under ecological, financial, and political risk. Many low and middle-income countries, which are most vulnerable to climate change, often lack the capacity to gather quality data. Despite this, decision-makers need information today if they are to build resilience before it is too late. To overcome this, CORVI combines empirical and survey data from local experts using structured expert judgement to provide a more complete picture on how climate-related risks are impacting a city. CORVI is a valuable tool to identify and categorize risk across sectors, aid in the design of integrated policy solutions, and access climate investment to build resilient coastal cities.
