Nigerian floods last year that claimed hundreds of lives also caused up to $9 billion in damage, according to a .

The assessment, conducted in collaboration with the World Bank, placed the cost of the destruction in a range of $3.79 billion to $9.12 billion.

Floods are an annual scourge in Africa’s most populous nation but the damage done in 2022 was the worst in a decade, hitting 33 of the country’s 36 states, 64% of households and causing an “unprecedented disruption and destruction,” according to the NBS.

The report contained several recommendations for the future, including early warning systems, flood-risk financing and insurance, as well as a focus on post-disaster recovery to safeguard food security.

It comes as leaders from around the world gather in Dubai for the COP28 summit on how to tackle climate change.

Talks will include a discussion about how countries that industrialized early might compensate their developing counterparts who are first to suffer the worst impacts of global warming, which has had a particularly devastating impact on Africa.

This year, floods in Nigeria, Niger and Chad killed more than 800 people, according to a report by the World Weather Attribution. It found that climate-changing pollution has made severe seasonal rains in West Africa 80 times more likely and 20% worse than they might have been before the world industrialized.

A warming planet may exacerbate existing “chronic food insecurity” in the region, the researchers said in a , warning it could contribute to increasing conflicts that harm farming and access to markets.
