Deforestation of the Amazon rainforest though the annual rate of forest loss has generally been slowing since 2004. However, rates of deforestation jumped again in 2008, 2013 and 2015. In Brazil, the Instituto Nacional de Pesquisas Espaciais (INPE, or National Institute of Space Research) produces deforestation figures annually. Their deforestation estimates are derived from 100 to 220 images taken during the dry season in the Amazon by the Landsat satellite, also may only consider the loss of the Amazon rainforest – not the loss of natural fields or savannah within the Amazon biome. The native tribes of the Amazon have often been abused during the
Deforestation of the Amazon rainforest Amazon has resulted from farmers clearing land for small-scale subsistence agriculture or for mechanized cropland. Scientists using NASA satellite data found in 2006 that clearing for mechanized cropland had become a significant force in Brazilian Amazon deforestation. This change in land use may alter the region's climate. Researchers found that in 2003, a peak year of deforestation, more than 20 percent of the Mato Grosso state's forests were converted to cropland. In 2005, soybean prices fell by more than 25 percent and some areas of Mato Grosso showed a decrease in large deforestation events, suggesting that the rise and fall
