Direct drivers of deforestation in Amazon countries Cattle ranching Cattle ranching is the leading cause of deforestation in the Amazon rainforest.

Causes of Deforestation. For the most part, human activity is to blame for deforestation, though natural disasters do play a role. So let's take a look at how and why humans deforest areas.Logging, or cutting down trees in a forest to harvest timber for wood, products or fuel, is a primary driver of deforestation.armers clear the land for crops or for cattle and often will clear acres of land using slash and burn techniques -- cutting down trees and then burning them. Migratory farmers clear a forest area and use it until the soil becomes too degraded for crops. Then they move on and clear a new patch of forest.
