The article analyzes the spatio-temporal evolution of floods in the urban area of Douala (Cameroon) from a geohistorical approach. A database on floods is created using information from the press (from Cameroon Tribune journal), it allows to spatialize the events to understand which areas of Douala are the most frequently flooded. There has been an increase in the number of floods reported since 2010, which seems to correlate with the evolution of the city's urban footprint. Recurrently flooded urban areas are most often the informal neighborhoods built directly into flood-prone areas and whose growth has been significant since the 1990s. Data from the press also helped to study the evolution of the discourse on flood risk management. It remains strongly focused on crisis resolution, despite the context of climate change adaptation policies that develop projects to improve urban flood management.
