O impacto da regularização fundiária na economia verde
Estudo publicado pelo IPAM na revista Stanford Social Innovation Review Brasil, verificou a existência de 57 mil propriedades fora dos sistemas do INCRA, o que resulta em mais de 9,9 milhões de hectares de terras sem cadastro. Quando somadas às áreas já registradas...
Nitric and nitrous oxide fluxes from intensifying crop agriculture in the seasonally dry tropical Amazon–Cerrado border region
apid expansion and intensification of crop agriculture in the tropics may accelerate ecosystem losses of reactive nitrogen (N). We quantified emissions of nitric oxide (NO) and nitrous oxide (N2O) in forest, single-cropped soybean [Glycine max (L.) Merr.], and...
Riparian forests buffer the negative effects of cropland on macroinvertebrate diversity in lowland Amazonian streams
Riparian forests regulate stream ecosystems and biodiversity. Therefore, changes to riparian structure may threaten stream ecosystem function by triggering taxonomic and functional changes to aquatic communities. Because macroinvertebrate assemblages are sensitive...
The Latent Dirichlet Allocation model with covariates (LDAcov): A case study on the effect of fire on species composition in Amazonian forests
Understanding and predicting the effect of global change phenomena on biodiversity is challenging given that biodiversity data are highly multivariate, containing information from tens to hundreds of species in any given location and time. The Latent Dirichlet...
Amazônia em Chamas 7 – Desmatamento e fogo nas florestas públicas não destinadas
As florestas públicas não destinadas (FPND) fazem parte do Cadastro Nacional de Florestas Públicas, atualmente sob a responsabilidade do Serviço Florestal Brasileiro (SFB). Estas florestas ocupam uma superfície de 57,5 milhões de hectares, mais do que a área da...
Land Use Change Influences Ecosystem Function in Headwater Streams of the Lowland Amazon Basin
Intensive agriculture alters headwater streams, but our understanding of its effects is limited in tropical regions where rates of agricultural expansion and intensification are currently greatest. Riparian forest protections are an important conservation tool, but...
Under-Reporting of COVID-19 Cases Among Indigenous Peoples in Brazil: A New Expression of Old Inequalities
To estimate the incidence, mortality and lethality rates of COVID-19 among Indigenous Peoples in the Brazilian Amazon. Additionally, to analyze how external threats can contribute to spread the disease in Indigenous Lands. Through this investigation it was possible...
