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.

Deforestation of the Amazon rainforest In the pre-Columbian era, parts of the Amazon Rainforest were a densely populated open agriculture. After the European colonization in the 16th century, with the hunt for gold, Western diseases, slavery and later the rubber boom, the Amazon Rainforest was depopulated and the forest grew larger. Prior to 1974s, access to the forest's largely roadless interior was difficult, and aside from partial clearing along rivers the forest remained intact. Deforestation accelerated greatly following the opening of highways deep into the forest, such as the Trans-Amazonian highway in 1972. In parts of the Amazon, the poor soil made plantation-based agriculture unprofitable.
