Also wanted to repeat (maybe in a more appropriate place):

Amazonian Harvest: Can prehistoric farming methods lead us to a sustainable future?by Mara Hvistendahl
"If we were to apply [pre-Columbian] techniques, it would be much better for the world....""This is like finding potsherds," he says. The leaf belongs to the cacao tree, which grows throughout this part of the country, the Beni, in circular patches called forest islands--telltale signs, he believes, of early settlement.
Erickson has worked in Bolivia and Peru for three decades, and he hopes his research will bring the lessons of the past to bear on the present, perhaps guiding sustainable agriculture here and across the globe. He is part of a growing group of archaeologists who are engaging and helping shape the communities in which they work, but a few decades ago, other scholars would have thought him crazy.
"He sees forest islands supplemented with raised fields of corn, tobacco, beans, and pumpkin--an agricultural cornucopia that will enrich the earth for future generations."

...like a Garden of Eden?
This article also mentions
Bio-char and Amazonian Dark Earths,
Terra Pretta.
The evidence in this article confirms scenarios presented in the book,
1491 IMHO.
...and while Hansen mentions the large carbon sequestration potential of forest and agricultural lands,
Bio-char can turn marginal, unproductive, even acid and/or aluminum laden soils, into dark rich productive farmlands.
In addition to converting marginal soils into large carbon sinks,
Bio-char can double or triple the CO2 sequestration (along with the productivity) of many agricultural soils and some forest soils, while reducing nitrogen and methane emissions from those soils.
...as long as Water Management, the ultimate challenge, is included.
