Amazon forest has been inhabited since the beginning of humanity. It is esteemed that some million of indigenous people already lived here when European colonists arrived in the region in XVI century. The modern occupation of the Amazon forest started around 1540, however, until the end of the Second World War, the human being presence almost did not change the environment and natural vegetal covering. A new period started with the politics, mainly in Brazil, aiming at the agricultural development and the nesting of immigrants, deriving of densely populated and/or devoid regions. All these modifications in the Amazon region can have climatic, ecological and ambient implications for the region, the continent and the globe.

The INPA (National Institute of Research of the Amazon region) has given an important contribution to the scientific and technological knowledge of the Amazon region. The set of this knowledge constitutes the greatest and more important bank of scientific information on the Amazon region, whose consultation became indispensable for a correct creation of regional public politics.
