This journal entry examines the relationship between climate change and flood risks in Nigeria,
as well as the adaptation strategies used by households and government agencies. Using a mixed
methods approach, including rainfall data analysis, household surveys (n=320), and interviews
with disaster officials, the study finds that extreme rainfall events have increased by 35% in coastal
Nigeria since 1990. Floods now occur four times more frequently than they did forty years ago.
However, adaptation efforts remain weak. Only 17% of at-risk households have access to early
warning systems. Government spending favours emergency response (81% of flood-related
budget) over prevention (19%). The study concludes that Nigeria requires a national flood plain
management law, community-based warning systems, and a funded relocation program for high
risk areas. Without these measures, flood losses will continue to rise as the climate changes.
