Not sure if it is relevant, but the article I read that mentioned TP in
Africa referred to 'West African rainforest". Here is the quote:

"Scientists who long debated the capacity of 'savages' to transform the
virgin rainforest now agree that indigenous people transformed large regions
of the Amazon and the West African rainforest into amazingly fertile black
earth."

Evidently Nigeria has the largest West African rainforest, though 90% of it
has been lost in the past couple of decades.
