Publisher Summary
This chapter presents the empirical evidence to justify the rejection of existing hypotheses about the productivity of Amazonian ecological zones relative to subsistence technology. The first body of evidence to be presented has to do with the agricultural potential of the major Amazonian tropical forest soils and others like them. This evidence shows that despite arguments to the contrary by anthropologists and geographers, Meggers' evaluation of agricultural potential in the Amazonian tropical forests is correct. The sustained-yield intensive cultivation of the major Amazonian tropical forest soils is not possible with aboriginal methods, and it may not be possible even with modern agricultural methods. The character of the major tropical forest soils of the Amazon lowlands is a product of their long geological history. The parent materials of these soils are the long and intensely weathered products of the erosion of rocks in the Andes mountains and Guiana and Brazilian shields.
