The Conversation reports the threat to African heritage sites posed by climate change:

'Villages and towns associated with the historic Swahili Indian Ocean trading networks are all forecast to suffer significant loss from sea-level rise and coastal erosion in the coming decades...
'A host of unique heritage locations are built on coral, sand or mud – all at elevations less than 10 metres above sea level.'
Among these sites is Mahilaka, the first major urban center and trading port in Madagascar, which was settled by Austronesians in the first millennium CE. Mahilaka is on the northwest coast. Archaelogical evidence is in the form of human artefacts, but also crop species not native to Africa, and maybe even linguistic traces in the Bantu language. There are indications that the neighbouring Comoros islands may have shared some of this Pacific (among others) immigration history.
