As today is World Environment Day, The Brazilian Report is republishing a study by the Amazonian Georeferenced Socio-Environmental Information Network (RAISG), mapping the pressures and threats faced by the Amazon forest region. This is the third part of the series, focusing on deforestation. The other parts, covering transport infrastructure and extractive industries, can be found here and here.
The Pan-Amazonia region is suffering serious impacts. With investments in infrastructure, there is degradation of forest ecosystems as a consequence of deforestation. But this is not the only parameter. Non-forest ecosystems experience loss of endemic species, replacement of their original vegetation by invasive species or by species resistant to fire. Or again, there is impoverishment caused by the establishment of unnatural savanna ecosystems, resulting from changes in the ecological processes linked to alterations in hydrological systems.
