Publication of the Data Processing behind the Climate-Conflict-Vulnerability Index
2 June 2025
After more than two years of development, the data processing behind the Climate-Conflict-Vulnerability Index (CCVI) is now published as open-source code. Following the scientific principle of transparency, anyone interested can now examine what choices we made, replicate the index and set up their own versions.
The CCVI is the result of a joint research project between the Center for Crisis Early Warning (CCEW) , the FutureLab "Security, Ethnic Conflicts and Migration" at the Potsdam Institute for Climate Impact Research (PIK), and the German Federal Foreign Office. The CCVI was launched publicly by then Foreign Minister Annalena Baerbock at the Berlin Climate and Security Conference 2024.
The goal of the project is to establish a scientifically informed tool that enables policymakers and researchers to assess and map current global risks to human security arising from climate and conflict hazards, their intersections and the potential for harmful interactions. Additionally, the CCVI reveals how vulnerabilities can amplify the impacts of climate and conflict hazards, increasing risks to human security.
The data processing is available on GitHub at: https://github.com/ccew-unibw/ccvi-data. The data is updated quarterly and gridded to 0.5 degrees (ca. 55km by 55km at the equator).
The data and documentation of our conceptual and technical approach are available at: https://climate-conflict.org.
