History[ edit ] Chief Raonione of the main opponents of deforestation of the Amazon rainforest In the pre-Columbian eraparts of the Amazon Rainforest were a densely populated open agriculture.
After the European colonization in the 16th century, with the hunt for goldWestern diseases, slavery and later the rubber boom, the Amazon Rainforest was depopulated and the forest grew larger. In parts of the Amazon, the poor soil made plantation-based agriculture unprofitable. The key turning point in deforestation of the Brazilian Amazon was when colonists began to establish farms within the forest during the s.
Their farming system was based on crop cultivation and the slash-and-burn method.
However, the colonists were unable to successfully manage their fields and the crops due to the loss of soil fertility and weed invasion due to this method. The rainforest is seen as a resource for cattle pasture, valuable hardwoods, housing space, farming space especially for soybeansroad works such as highways and smaller roads and medicines.
Scientists using NASA satellite data found in that clearing for mechanized cropland had become a significant force in Brazilian Amazon deforestation.
Ina number of major commodity trading companies such as Cargill agreed to not purchase soybeans produced in the Brazilian Amazon in recently deforested areas.
Before the moratorium, 30 percent of soy field expansion had occurred through deforestation, contributing to record deforestation rates. After eight years of the moratorium, a study found that although soy production area had expanded another 1.
In response to the moratorium, farmers were choosing to plant on already cleared land. The completion of the roads was followed by a wave of resettlement; these settlers had a significant effect on the forest as well.
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. Most of this lost forest was replaced by pasture for cattle. Today the remaining forest cover continues to dwindle, though the annual rate of forest loss has generally been slowing since However, rates of deforestation jumped again in  and 4 days ago · Brazil has released its worst annual deforestation figures in a decade amid fears that the situation might worsen when the avowedly anti-environmentalist president-elect Jair .
