HANZE combines data on exposure (inventory of people and assets who could be affected by a natural hazard) with data on actual losses (currently only from floods). This allows to „normalize” flood losses by taking into account local-scaledemographic, economic and land-use change. Here, such an analysis is done first time in such spatial and temporal extent.
