Abstract Tropical secondary forests sequester carbon up to 20 times faster than old-growth forests. This rate does not capture spatial regrowth patterns due environmental and disturbance drivers. Here we quantify the influence of such drivers on in Brazilian Amazon using satellite data. Carbon sequestration rates young (<20 years) west are ~60% higher (3.0 ± 1.0 Mg C ha −1 yr ) compared those east (1.3 0.3 ). Disturbances reduce by 8–55%. The 2017 forest stock, 294 Tg C, could be 8%...
Indigenous societies are known to have occupied the Amazon basin for more than 12,000 years, but scale of their influence on Amazonian forests remains uncertain. We report discovery, using LIDAR (light detection and ranging) information from across basin, 24 previously undetected pre-Columbian earthworks beneath forest canopy. Modeled distribution abundance large-scale archaeological sites Amazonia suggest that between 10,272 23,648 remain be discovered most will found in southwest. also...
The Amazon Basin is at the center of an intensifying discourse about deforestation, land-use, and global change. To date, climate research in has overwhelmingly focused on cycling storage carbon (C) its implications for climate. Missing, however, a more comprehensive consideration other significant biophysical feedbacks [i.e., CH 4 , N 2 O, black carbon, biogenic volatile organic compounds (BVOCs), aerosols, evapotranspiration, albedo] their dynamic responses to both localized (fire,...
While the climate and human-induced forest degradation is increasing in Amazon, fire impacts on dynamics remain understudied wetter regions of basin, which are susceptible to large wildfires only during extreme droughts. To address this gap, we installed burned unburned plots immediately after a wildfire northern Purus-Madeira (Central Amazon) 2015 El-Niño. We measured all individuals with diameter 10 cm or more at breast height conducted recensuses track demographic drivers biomass change...
Abstract Atmospheric methane concentrations were nearly constant between 1999 and 2006, but have been rising since by an average of ~8 ppb per year. Increases in wetland emissions, the largest natural global source, may be partly responsible for this rise. The scarcity situ atmospheric observations tropical regions one source large disparities top-down bottom-up estimates. Here we present 590 lower-troposphere vertical profiles concentration from four sites across Amazonia 2010 2018. We find...
Full-waveform LiDAR (FWF) offers a promising advantage over other technologies to represent the vertical canopy structure of secondary successions in Amazon region, as waveform encapsulates properties all elements intercepting emitted beam. In this study, we investigated modifications Amazonian across vegetation gradient from early advanced stages regrowth. The analysis was performed two distinct climatic regions (Drier and Wetter), designated using Maximum Cumulative Water Deficit (MCWD)....
Abstract A quarter of the deforested Amazon has regrown as secondary tropical forest and yet climatic importance these complex regenerating landscapes is only beginning to be recognised. Advances in satellite remote-sensing have transformed our ability detect map changes cover, while detailed ground-based measurements from permanent monitoring plots eddy-covariance flux towers are providing new insights into role forests climate system. This review summarises how progress data availability...
Quantifying forest fires remain a challenging task for the implementation of public policies aimed to mitigate climate change. In this paper, we propose new method provide an annual burned area map Mato Grosso State located in Brazilian Amazon region, taking advantage high spatial and temporal resolution sensors.

With deforestation and associated fires ongoing at high rates, amidst urgent need to preserve Amazonia, improving the understanding of biomass burning emissions drivers is essential. The use orbital remote sensing data enables estimate both deforestation. In this study, we have estimated particulate matter with diameter less than 2.5 µm (PM2.5) burning, a primary human health risk, using Brazilian Biomass Burning emission model Fire Radiative Power (3BEM_FRP), based on MapBiomas dataset....
Abstract. Tropical forests such as the Amazonian rainforests play an important role for climate, are large carbon stores and a treasure of biodiversity. have been exposed to large-scale deforestation degradation many decades. Deforestation declined between 2005 2012 but more recently has again increased with similar rates in 2007–2008. The resulting forest fragments substantially elevated temperatures already warming world. These temperature land cover changes expected affect forests,...
Secondary forests (SF) are important carbon sinks, removing CO2 from the atmosphere through photosynthesis process and storing photosynthates in their aboveground live biomass (AGB). This occurring at large-scales partially counteracts C emissions land-use change, playing, hence, an role global cycle. The absorption rates of these depend on forest physiology, controlled by environmental climatic conditions, as well past land use, which is rarely considered for retrieving AGB remotely sensed...
Brazil, with more than 8 million km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , presents six different biomes, ranging from natural grasslands (Pampa biome) to tropical rainfall forests (Amazônia biome), land-use types (mostly pasturelands and croplands) pressures (mainly in the Cerrado biome).

This article presents a method, based on orbital remote sensing, to map the extent of forest plantations in São Paulo State (Southeast Brazil). The proposed method uses random machine learning algorithm available Google Earth Engine (GEE) cloud computing platform. We used 30 m annual mosaics derived from Landsat-5 Thematic Mapper (TM) images and Landsat-8 Operational Land Imager (OLI) for 1985 1995 2013 2021 time periods, respectively. These periods were selected planted areas’ rotation,...

Amazon forests are the largest in tropics and play a fundamental role for regional global ecosystem service provision. However, they under threat primarily from deforestation. Amazonia's carbon balance trend reflects condition of its forests. There different approaches to estimate large-scale balances, including top-down (e.g., CO 2 atmospheric measurements combined with transport information) bottom-up land use cover change (LUCC) data based on remote sensing methods). It is important...
