In this session, speakers presented their approaches to collect and validate data on the impact of disasters. This data is crucial for anticipatory humanitarian action when forecasting the impact of disasters or defining triggers. Impact data is sourced on various levels and range from local to national and global level using local government archives, newspaper articles, or international organizations. There was clear agreement that the validation of data is crucial to be able to use and publish these databases and to adjust datasets to country and local contexts more.
