Combining approaches for environmental assessment of rehabilitated gold‐mining areas in the Eastern Amazon
Monitoring key soil and vegetation attributes in mining areas under environmental rehabilitation is essential to ensure that the intervention techniques are effective. There are several approaches to monitoring mining areas and their integration is necessary to process large amounts of information. Thus, this study aimed to (i) assess soil multi‐contamination with potentially toxic elements (PTE) and human health risks; (ii) obtain a soil quality…
Mapping soil organic carbon stock through remote sensing tools for monitoring iron minelands under rehabilitation in the Amazon
Land‐use intensity of official mineral extraction in the Amazon region
The Amazon region has suffered considerable deforestation rates related to logging, cattle ranching, and agriculture. Recently, attention has been given to deforestation due to mining activities. This paper aims to estimate the land area affected by mining activities in protected and nonprotected areas, the value of the traded mineral extraction per commodity, and the mineral commodity with the highest trade (mineral extraction per mining area). …
Forecasting deforestation in the Brazilian Amazon to prioritize conservation efforts
As Amazon deforestation rates reach the highest levels observed in the past decade, it is extremely important to direct conservation efforts to regions containing preserved forests with a high risk of deforestation. This requires forecasting deforestation, a complex endeavor due to the interplay of multiple socioeconomic, political, and environmental factors across different spatial and temporal scales. Here we couple high-resolution land-cover m…
Reconstructing Three Decades of Land Use and Land Cover Changes in Brazilian Biomes with Landsat Archive and Earth Engine
Brazil has a monitoring system to track annual forest conversion in the Amazon and most recently to monitor the Cerrado biome. However, there is still a gap of annual land use and land cover (LULC) information in all Brazilian biomes in the country. Existing countrywide efforts to map land use and land cover lack regularly updates and high spatial resolution time-series data to better understand historical land use and land cover dynamics, and th…
Land cover change, landscape degradation, and restoration along a railway line in the Amazon biome, Brazil
Railways are known to have less influence on land use than other transportation systems. However, railways also affect biodiversity, water resources, socioeconomic outcomes, and land prices. In the context of changes in land cover and land use (LCLU) classes, this study analyses the changes arising from the establishment of the Carajás Mining Project in 1984 along the more than 900‐km length of the Carajás Railway (CRW) in southeastern Amazonia. …

Modern pollen rain as a background for palaeoenvironmental studies in the Serra dos Carajás, southeastern Amazonia
Several alternative interpretations of the pollen records of lake sediments in the Amazonia may arise due to a lack of understanding of the modern environments, mainly related to pollen–vegetation relationship. Therefore, in this work, we studied the modern pollen rain in sediments of the Amendoim Lake, plateaus of the Serra Sul dos Carajás, southeastern Amazonia. This study indicates the predominance of pollen grains from forest formation (ombro…
Dinâmica socioambiental na Vila dos Pescadores (Amazônia Oriental, Pará, Brasil)
Este trabalho descreve os aspectos sociais, econômicos e ambientais de uma comunidade de pescadores(Vila dos Pescadores), situada no estuário do Rio Caeté, no nordeste do Pará (Brasil). A metodologiaadotada neste estudo foi baseada em entrevistas, questionários e observação direta para caracterizaralguns aspectos sociais, econômicos e ambientais, bem como no monitoramento de perfis de praia,para determinar a dinâmica costeira local. Os resultados…
