Relatório de Atividades 2024
O ano de 2024 nos deu alguns motivos para seguir acreditando que é possível reverter um cenário de colapso global. Vimos a redução do desmatamento continuar na Amazônia e o Cerrado começar a acompanhar essa tendência. Mas é preciso mais que isso. Passamos pelo ano...
The effects of deforestation and climate variability on the streamflow of the Araguaia River, Brazil
Deforestation changes the hydrological, geomorphological, and biochemical states of streams by decreasing evapotranspiration on the land surface and increasing runoff, river discharge, erosion and sediment fluxes from the land surface. Deforestation has removed...
The 2010 Amazon Drought
In 2010, dry-season rainfall was low across Amazonia, with apparent similarities to the major 2005 drought. We analyzed a decade of satellite-derived rainfall data to compare both events. Standardized anomalies of dry-season rainfall showed that 57% of Amazonia had...
Carbon Inputs and Water Uptake in Deep Soils of an Eastern Amazon Forest
Rooting depth affects soil profiles of water uptake and carbon inputs. Here we explore the importance of deep roots in a mature tropical forest of eastern Amazonia, where a throughfall exclusion experiment was conducted to test the resilience of the forest to...
Conversion to soy on the Amazonian agricultural frontier increases streamflow without affecting stormflow dynamics
Large-scale soy agriculture in the southern Brazilian Amazon now rivals deforestation for pasture as the region's predominant form of land use change. Such landscape-level change can have substantial consequences for local and regional hydrology, but these effects...
Size, species, and fire behavior predict tree and liana mortality from experimental burns in the Brazilian Amazon
Anthropogenic understory fires have affected large areas of tropical forest in recent decades, particularly during severe droughts. Yet, the mechanisms that control fire-induced mortality of tropical trees and lianas remain ambiguous due to the challenges...
Agriculture in Brazil: impacts, costs, and opportunities for a sustainable future
Brazil has developed a large-scale commercial agricultural system, recognized worldwide for its role in domestic economic growth and expanding exports. However, the success of this sector has been associated with widespread destruction of Brazilian ecosystems,...
