>Don't even get started on the slave trade, africans have sold africans into slavery
That's cool bro. But that has nothing to do with my point, I was just explaining why the number stagnated.

>Once again, winter in europe kills 100% of those who can't farm and store crops. Not the situation in africa. Africans were able to continue living, even in subpar conditions, and so never developed the agricultural skills that europeans and others did.
Again, they had frequent prolonged droughts, more pests, and soil erosion, that are 100% guaranteed to kill everyone that can't put up crops before the yearly wet season and the next drought. European monocultures are adapted to temperate climates, as it involves leaving the soil without crop cover for lengthy periods. There is no protection against heavy tropical rains which causes splash erosion that significantly reduces soil fertility. On the other hand, African farmers had to hurry against crop damage and flooding because of higher chances of soil erosion.

And btw, Europeans in the New World relied on the skills of Africans to cultivate rice(Oryza Glabberima) in South Carolina and Louisiana.

Here is a comment on the rice system :
>“By integrating variation in soil type, topography and moisture regimes with food production objectives, West African farmers have managed to evolve an agricultural system that minimises the impact of production constraints. The first Portuguese to reach the Senegambian littoral in 1444 marvelled at the human ingenuity that had crafted this food production system - just as do those who study its operation more than five hundred years later." (Judith Carney, "Indigenous Soil and Water Management in Senegambian Rice Farming Systems." Agriculture and Human Values, Winter-Spring, 1991).
