I was quite shocked by the landscape driving through many parts of West Africa. I always assumed places like Gabon, Republic of Congo and the Democratic Republic of Congo (DRC) would be 99% dense jungle given they're right on the equator.
In some places they are, but also there are immense swaths of green rolling hills that stretch to the horizon on all sides. [1]
Speaking to locals they didn't think "modern" humans had deforested like that - the evidence would have been visible, and everyone agreed it would have been impossible to deforest that much landscape without at least steam powered tools.
Maybe fire explains some of it, but I still don't really understand.
Amazingly, when I was on the other side of the continent a stone's throw from the Eastern side of the DRC, the landscape was virtually identical again. [2]

- AlotOfReading 6y agoAlmost everyone underestimates the capabilities of their ancestors and work over time. As an archeologist I've seen firsthand the remnants of rivers rerouted with stone tools and vast open plains created with grazing animals and/or fire. Humans are very good at changing landscapes, regardless of our level of technology. It gets quicker and less labor intensive with modern tools, but we can do it without them nonetheless.
- grecy 6y agoI certainly don't want to disagree with you, though the sheer scale of what I saw is difficult to believe. I'm talking in the order of a million square kilometres. (DRC alone is 2.3 mil...) Do you think that could be done with stone tools and fire?
- AlotOfReading 6y agoIn the general case, absolutely. Thousands of humans working for thousands of years can do impressive things. I don't have any particular knowledge of the grasslands of tropical africa and a quick look at the literature shows a pretty ambiguous situation that I'm not qualified to speak to, but the concept as a whole is one that I find reasonably plausible.
- rhodozelia 6y agoCheck out the forest fires in California and Oregon recently, Fire is a fast way to change a lot of land!
- detritus 6y agoModern technology allows us to seriously meddle with nature within a generation or two, whereas always prior it might've taken a few tens. Over time though, we've had thousands of generations to make our mark. I fundamentally believe that a lot of our desertified or at least somewhat dessicated Earth - around the mediterranean, sahara and middle east at least - is significantly due to our historical industry.
- treeman79 6y agoBeavers can change landscapes. No tools needed.
- pram 6y agoThat’s what happened to the Loess Plateau afaik. Doesn’t seem that unbelievable elsewhere, I agree.
