Accelerated climate change, especially since the last half of the twentieth century, is an additional challenge for the indigenous peoples of the Amazon, who depend directly on the resources of the territory. These include subsystems like agriculture (itinerant, semi itinerant and localized) art of hunting, art of fishing and silviculture. The space where humans unify themselves with nature (abiotic and biotic) allows the weaving of networks of territoriality, "spatial memory of social and communal time."
