Climate change has modified the geographic distribution and productivity of plants in tropical forests. I present considerations on the regions where extractivist and farmers are most threatened by climate change and discuss the changes in species composition that take place in Amazonia. The increase in atmospheric CO2 can stimulate more carbohydrates, lipids, and vegetable proteins in non-timber forest products for economic use in Amazonia. However, the increase in forest productivity has been limited by increased temperature, vapor pressure deficit, drought, forest fires, and deforestation. The density of some species of palms, Cecropia and Vismia, are increasing in degraded areas, but native Amazonia species, such as acai berry, andiroba, and Brazil nut, are decreasing. Forest-dependent extractivist and farmers are most threatened by climate change in municipalities in the southern and eastern regions in Brazilian Amazonia.
