Studies showed that Brazilian Amazon indigenous territories (ITs) are efficient models for preserving forests by reducing deforestation, fires, and related carbon emissions. Considering the importance of ITs for conserving socio-environmental and cultural diversity and the recent climb in the Brazilian Amazon deforestation, we used official remote sensing datasets to analyze deforestation inside and outside indigenous territories within Brazil's Amazon biome during the 2013-2021 period. Deforestation has increased by 129% inside ITs since 2013, followed by an increase in illegal mining areas. In 2019-2021, deforestation was 195% higher and 30% farther from the borders towards the interior of indigenous territories than in previous years (2013-2018). Furthermore, about 59% of carbon dioxide (CO) emissions within ITs in 2013-2021 (96 million tons) occurred in the last three years of analyzed years, revealing the magnitude of increasing deforestation to climate impacts. Therefore, curbing deforestation in indigenous territories must be a priority for the Brazilian government to secure these peoples' land rights, ensure the forests' protection and regulate the global climate.
研究表明，巴西亚马逊土著领土（IT）是通过减少森林砍伐、火灾和相关碳排放来保护森林的有效模式。考虑到 IT 对于保护社会环境和文化多样性的重要性以及巴西亚马逊地区最近的森林砍伐上升，我们使用官方遥感数据集来分析 2013 年至 2021 年期间巴西亚马逊生物群落内和 IT 内的森林砍伐情况。自 2013 年以来，IT 内的森林砍伐增加了 129%，随后非法采矿区增加。2019 年至 2021 年，与前几年（2013-2018 年）相比，森林砍伐增加了 195%，且距离 IT 边界向内部的距离增加了 30%。此外，2013 年至 2021 年期间（9600 万吨），IT 内约 59%的二氧化碳（CO）排放发生在分析年份的最后三年，这揭示了森林砍伐对气候影响不断增加的程度。因此，遏制 IT 内的森林砍伐必须成为巴西政府的优先事项，以确保这些人民的土地权、保护森林并调节全球气候。
