Amazônia em Chamas nº 12 – entendendo a relação entre o fogo e desmatamento em 2023
Apesar da redução de 50% no desmatamento na Amazônia, a pior seca em 125 anos aumentou o fogo em outras áreas do bioma, elevando a área queimada total para 10 milhões de hectares, 36% a mais do que em 2022. Dados foram publicados Nota Técnica Amazônia em Chamas nº...
What lies behind decentralisation? Forest, powers and actors in lowland Bolivia
Bolivia has undertaken important policy reforms since the mid-1990s aimed at institutionalising popular participation and promoting democratic decentralisation. In the forestry sector, municipal governments have received responsibilities and various mechanisms have...
The role of informal contracts in the growth of small cattle herds on the floodplains of the Lower Amazon
In the absence of access to formal credit, informal contracts with independent investors give the small ranchers of the Lower Amazon an acceptable means through which to surmount the high investment hurdle of starting a cattle herd. These contracts – called...
The Large‐Scale Biosphere‐Atmosphere Experiment in Amazonia: Analyzing Regional Land Use Change Effects
The Brazilian Amazon currently releases about 0.2 Pg-C to the atmosphere each year as a result of net deforestation. Logging and forest fire activity are poorly quantified but certainly increase this amount by more than 10%. Fires associated with land management...
Activity patterns and diet of the howler monkey Alouatta belzebul in areas of logged and unlogged forest in Eastern Amazonia
This work compared the activity patterns and diet of a group of Alouatta belzebul in areas of logged and unlogged forest in eastern Amazonia.
Classifying successional forests using Landsat spectral properties and ecological characteristics in eastern Amazônia
Secondary forests may become increasingly important as temporary reservoirs of genetic diversity, stocks of carbon and nutrients, and moderators of hydrologic cycles in the Amazon Basin as agricultural lands are abandoned and often later cleared again for...
Contribution of transpiration to forest ambient vapour based on isotopic measurements
Using a simple isotope mixing model, we evaluated the relative proportion of water vapour generated by plant transpiration and by soil evaporation at two sites in the Amazon basin. Sampling was carried out at two different soil covers (forest and pasture), in a...
