Studies showed that Brazilian Amazon indigenous territories (Its) are efficient models for preserving forests by reducing deforestation, fires, and related carbon emissions. Here, we used official remote sensing datasets to analyze deforestation inside and outside indigenous territories within Brazil's Amazon biome in the 2013-2021 period. We found that deforestation has increased by 129% inside ITs since 2013, followed by an increase in illegal mining areas. In the 2019-2021 period, deforestation was 195% higher and 30% further from the borders towards the interior of indigenous territories than in previous years (2013-2018). Furthermore, about 59% of carbon dioxide (CO2) emissions within ITs in the 2013-2021 period (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.

“…These findings suggest that the increase in deforestation inside ITs (Fig. 1 ), induced by recent environmental setbacks 23 , 32 , may reverse the vital role of these protected areas in combating climate change 33 by avoiding deforestation. Previous work that analyzed past periods found that Brazilian Amazon protected areas are efficient in preventing deforestation 10 , 34 – 38 ; however, in the most recent period, we have found evidence to argue that the role of ITs is being counteracted by the weakening of governance, decrease in the protection and rights of indigenous people 19 , 22 – 25 .…”

“…However, the most worrying point is that only in half of the 2022 year, mining is already equivalent to 19% of all deforestation notices 26 in the analyzed ITs. Recent environmental setbacks, which include political speech, can explain the increased illegal mining activity in ITs 23 , 32 , besides the possibility of regulating commercial mining in these territories 41 , 43 , 44 . Combined with setbacks, the rise in the gold price in recent years has increased pressure on these protected areas; in the 2019–2021 period, the gold price increased more than 30%, reaching up to $65 g −1 , the highest value of the last ten years ( https://goldprice.org ).…”

“…This time window was adopted as it was considered a period of a new deforestation climb in the Brazilian Amazon 19 . Therefore, we adopted two analysis periods, before (2013–2018) and during the current environmental setback intensification period (2019–2021) 23 , 32 . Each dataset is described below.…”

“…Thus, to accurately diagnose deforestation dynamics in the Brazilian Amazon ITs, we used two official remote sensing datasets and statistical analyses to perform a space–time assessment of deforestation in indigenous territories within the Brazilian Amazon biome between 2013 and 2021; we adopted this time window because it was considered a period of a new deforestation climb in the Brazilian Amazon 19 , mainly in the 2019–2021 period when there was an intensification of environmental setbacks in the region 23 , 32 . Considering the importance of ITs for conserving socio-environmental and cultural diversity and the recent climb in the Brazilian Amazon deforestation, we provide to answer the following questions: (1) Was there a significant trend in deforestation rates inside and outside ILs between 2013 and 2021?…”

An alert system for Seasonal Fire probability forecast for South American Protected Areas

et al. 2021

Timely spatially explicit warning of areas with high fire occurrence probability is an important component of strategic plans to prevent and monitor fires within South American (SA) Protected Areas (PAs). In this study, we present a five-level alert system, which combines both climatological and anthropogenic factors, the two main drivers of fires in SA. The alert levels are: High Alert, Alert, Attention, Observation and Low Probability. The trend in the number of active fires over the past three years and the accumulated number of active fires over the same period were used as indicators of intensification of human use of fire in that region, possibly associated with ongoing land use/land cover change (LULCC).
