Climate benefits of Amazon secondary forests—recent advances and research needs
A quarter of the deforested Amazon has regrown as secondary tropical forest and yet the climatic importance of these complex regenerating landscapes is only beginning to be recognised. Advances in satellite remote-sensing have transformed our ability to detect and...

Amazônia em chamas 3: O fogo e o desmatamento em 2019 e o que vem em 2020
Com a época mais intensa de desmatamento na Amazônia se aproximando, é hora de fazer um balanço do que aconteceu na região em 2019. É hora também de colocar em curso estratégias de enfrentamento do desmatamento, que nos três primeiros meses deste ano aumentou...
Fire as a fundamental ecological process: Research advances and frontiers
Fire is a powerful ecological and evolutionary force that regulates organismal traits, population sizes, species interactions, community composition, carbon and nutrient cycling and ecosystem function. It also presents a rapidly growing societal challenge, due to...
A better Amazon road network for people and the environment
In the next 5 y, more than 10 thousand kilometers of roads will be built or improved in the Amazon. Well-designed projects can increase employment opportunities, reduce transport costs, and support regional development. However, roads will also drive...
Mapping Three Decades of Changes in the Brazilian Savanna Native Vegetation Using Landsat Data Processed in the Google Earth Engine Platform
Widespread in the subtropics and tropics of the Southern Hemisphere, savannas are highly heterogeneous and seasonal natural vegetation types, which makes change detection (natural vs. anthropogenic) a challenging task. The Brazilian Cerrado represents the...
Potential shifts in the aboveground biomass and physiognomy of a seasonally dry tropical forest in a changing climate
Seasonally dry tropical forests (SDTFs) account for one-third of the interannual variability of global net primary productive (NPP). Large-scale shifts in dry tropical forest structure may thus significantly affect global CO2 fluxes in ways that are not fully...
