Amazonian dark earths (ADE) are anthropogenic soils with concentrated carbon and nutrients that formed mainly during the latter half of the Holocene, prior to the arrival of Europeans, but are still forming on a more limited scale up to the present in indigenous communities. ADE, a result of domestic, economic, and agricultural activities in and around human settlements, are noted for their extraordinary fertility and resilience and for the significant quantities of organic carbon, much in the form of charcoal. The deepest and most extensive areas of ADE are generally located on the bluffs of major rivers adjacent to floodplains, but significant areas of ADE have also been found in floodplains and in headwater and interfluvial areas. Our research aims to shed light on the distribution of modified soils in distinct regions of the Amazon in relation to landforms and the environment. Research on ADE has led to the development of a 'biochar' industry that promotes the incorporation of charcoal into the soil for the dual purpose of improving fertility and sequestering carbon, but the potential for large-scale carbon storage in anthropogenic soils is unclear, in part because the amount of carbon already stored in ADE is unknown as there is a notable lack of research attempting to quantify the carbon over the scale of a site or region. We undertook this challenge in the Upper Xingu region of southeastern Amazonia in partnership with the local Kuikuro indigenous community who have shared their valuable traditional knowledge on the creation and management of ADE. We used data from over 3500 soil samples from diverse contexts, both ancient and modern, that we collected and analyzed over the past two decades for organic carbon and a range of other chemical and physical properties that can serve as proxies for soil modification by humans. Dark earth samples from profiles down to 1 m depth in archaeological sites ranged from 20% to 150% more OC than unmodified forest soil and dark earth profiles in current and historic villages ranged from 20-90% more organic carbon. We used the results from soil sample transects to estimate the carbon in landuse zones within and surrounding modern, historic, and ancient settlement sites. In continuing work, we are attempting to use satellite remote sensing and AI to extrapolate our results across a larger region.

A mandioca (Manihot esculenta Crantz) e uma euforbiaceae de origem americana, cultivada desde a antiguidade. Assume posicao destacada na atual conjuntura mundial em razao do alto teor de carbohidratos existentes em suas raizes, usadas como materia-prima para varios produtos industrializados (alcool anidro, amido, farinha de mesa, etc) e, tambem, na alimentacao humana e animal. Pode ser cultivada na faixa tropical compreendida entre os paralelos de 30 graus de latitude norte e sul, suportando altitudes que variam desde o nivel do mar a cerca de 2.000m na regiao equatorial. |
