The Amazon Rainforest, crucial for climate regulation, carbon and water cycles, and biodiversity preservation, faces escalating threats from heightened forest degradation, including disturbances from fire and logging. In 2020, Brazil was responsible for a concerning 70% of the active fire hotspots detected in the Amazon, signaling a notable 60% inc...
Anthropogenic disturbances stand as the primary driver of degradation in the remaining Amazon forests, posing a significant threat to their future. Notable among these disturbances are edge effects, timber extraction, fire, extreme droughts and temperatures, which have been intensified by human-induced climate change. A pilot study aiming to integr...
In recent years, the loss of forest in the Brazilian Amazon has taken on alarming proportions, with 2021 recording the largest increase in 13 years, particularly in the Abunã-Madeira Sustainable Development Reserve (SDR). This has significant environmental, social, and economic repercussions globally and for the local communities reliant on the for...
Airborne LiDAR data represents one of the most accurate ways to
estimate forest structure and carbon nowadays. This study aimed to estimate the intensity of selective logging activities in terms of density and volume of logged trees based on airborne LiDAR data in comparison to ground measurements on a forest concession area in the Brazilian Amazon...
O estudo destaca a importância crítica da vegetação na Amazônia para a
estabilidade climática, mas ressalta os impactos severos do desmatamento,
especialmente nas atividades agrícolas, queimadas e infraestrutura. A região sudoeste da Amazônia enfrenta uma vulnerabilidade significativa à perda de serviços ecossistêmicos. Modelos espacialmente explíc...
Fires affect the Amazon rainforest and cause various socio-environmental problems. Analyses of forest fire dynamics supporting actions to combat and prevent forest fires. However, many studies have reported discrepancies in the quantification of fire, especially in the tropics. We evaluated four operational products for estimating burned areas (MAP...
Deforestation patterns and trajectories provide information that allows an understanding of occupation processes and the dynamics of deforestation in the Amazon. This understanding is needed for development of public policies to contain the advance of the deforestation frontier. We analyzed deforestation patterns and trajectories up to 2021 in Lábr...
RESUMO As mudanças do uso e ocupação da terra proporcionam diversas alterações na paisagem. A fragmentação florestal, que induz o crescimento das bordas e a perda da cobertura florestal, tem servido como um fator para o avanço das áreas queimadas no sudoeste da Amazônia. O objetivo desse trabalho foi analisar o papel da fragmentação florestal na oc...
RESUMO Boca do Acre constitui uma nova fronteira de expansão madeireira, ocupando o quarto lugar no estado do Amazonas áreas de exploradas. O objetivo deste estudo foi analisar a evolução da atividade madeireira e do desmatamento no período de 2007 a 2019 em Boca do Acre. Para isso, utilizamos a imagem-fração solo obtida pelo Modelo Linear de Mistu...
