Deforestation of the Amazon rainforest The completion of the roads was followed by a wave of resettlement; these settlers had a significant effect on the forest as well. Research conducted by Leydimere Oliveira et al. has shown that the more rainforest is logged in the Amazon, the less precipitation reaches the area and so the lower the yield per hectare becomes. Thus for Brazil as a whole, there is no economic gain to be made by logging and selling trees and using the logged land for pastoral purposes. A September 2016 Amazon Watch report concludes that imports of crude oil by the US are driving
Selective logging in the Amazon rainforest Amazonia. These migrations did not implement any new management techniques. Selective logging is the practice of removing only one or two tree species from a certain area. As mentioned before, selective logging is a more efficient method when compared to clear-cutting but there are still negative impacts. Selective logging in the Amazon rainforest has transitioned from low-volume harvests of one or two species to a system that can log multiple species and remain profitable. It is one of the many land uses in developing frontiers in the Amazon. However, the growth of this industry is not correlated with efficient management
