Socio-Environmental Impacts on Indigenous Lands in the Brazilian Amazon

This research revealed the main socio-environmental pressures on indigenous lands located in the Amazon Biome. To achieve the objectives, ten analysis variables were used [deforestation (area and proportion), hot spots, mining(mining in river, area of mining and mining in isolated points), predatory fishing, murders, illegal logging and the phases of landholding regulation]. The variables were organized in a database and crossed in a Geographic Information System environment through the association of weight, which have revealed quantitative values ​​to the variables. Thus, according to the proposed index, the results showed that five indigenous lands had 'Very High' pressure values, which corresponded to 1.5% of the total number of indigenous lands in the Amazon Biome. However, the majority showed a pressure classified as 'Low'. Therefore, despite the entire process of expropriation, indigenous lands remain relevant for the conservation and preservation of natural resources in the Amazon
