This Project Overview introduces the Investigate First, Invest Later Methodology for understanding and managing recurring flood risk in West Africa. It explains why repeated flood damage persists, why reactive spending often treats symptoms rather than causes, and how investigation, diagnosis, prioritisation, staged investment, learning, and adaptation can improve flood-risk decisions.
The Overview provides an accessible entry point to the wider West Africa Flood Risk publication family and the Complete White Book. It is intended for governments, cities, engineers, development partners, researchers, communities, practitioners, and concerned citizens seeking a clearer basis for flood-risk action and investment.
