To be honest, Europe would probably fulfil this if you just avoided the world wars. Without the enormous death toll and fleeing refugees, Europe could probably have a population of a billion or more. Even today, the continent has something like 750 million people, a lot of unused farmland in the East, and is a net food exporter. Some more peace and prosperity, particularly in the former Russian and Austro-Hungarian Empires could lead to a population boom in the Eastern end of the continent as industrialisation shifts eastwards and greater mechanisation of farming and better healthcare allows for urbanisation and lower childhood mortality.
Higher birth rates would easily compensate that, people tend to underestimate the effects of even small differences in birth rates over decades.Or if Europeans do not expand overseas. It would be a really crowded continent if all those tens of millions did not emigrate to the Americas, Australia, New Zealand, South Africa, etc.
the Amazon basin had a HUGE population pre-contact. It could have developed into a china-esque civ given enough time.
Does it? Where did you read that?If you want modern, modern-day Brazil currently feeds over a billion people.
Look at that, almost 60% of preserved land, and 9,2% degraded/under-utilized land. Between more technology and more efficient land use, I'm pretty sure Brazil could feed double that, triple that.
The real question is how are you going to make Brazil reach India-level popullations? Even assuming that the brazilian baby boom never stopped, I think you would need like five decades of it, and that's pretty much impossible in modern times. Even increasing immigration is probably not going to do it. You would have to call pretty much everyone and his mother for that.

You are assuming that the remaining land is of the same agricultural quality, which is probably not the case I'd suppose.
Have Brazil get colonized a few centuries earlier.If you want modern, modern-day Brazil currently feeds over a billion people.

Ok that will work. LolHave Brazil get colonized a few centuries earlier.
