“…The Amazon ecosystems harbor about 10 to 15% of land biodiversity (5,6); its abundant rainfall of about 2.2 m·y −1 makes the region an important heat source for the atmosphere (7), generating an estimated 210,000 m 3 ·s −1 to 220,000 m 3 ·s −1 of river discharge (8,9), which is ∼15% of the freshwater input into the oceans (10); it stores an estimated 150 billion to 200 billion tons of carbon (11)(12)(13)(14)(15); and it presents a mosaic of ethnological and linguistic diversity (16,17).…”

For half a century, the process of economic integration of the Amazon has been based on intensive use of renewable and nonrenewable natural resources, which has brought significant basin-wide environmental alterations. The rural development in the Amazonia pushed the agricultural frontier swiftly, resulting in widespread land-cover change, but agriculture in the Amazon has been of low productivity and unsustainable. The loss of biodiversity and continued deforestation will lead to high risks of irreversible change of its tropical forests. It has been established by modeling studies that the Amazon may have two "tipping points," namely, temperature increase of 4°C or deforestation exceeding 40% of the forest area. If transgressed, large-scale "savannization" of mostly southern and eastern Amazon may take place. The region has warmed about 1°C over the last 60 y, and total deforestation is reaching 20% of the forested area. The recent significant reductions in deforestation-80% reduction in the Brazilian Amazon in the last decade-opens up opportunities for a novel sustainable development paradigm for the future of the Amazon. We argue for a new development paradigm-away from only attempting to reconcile maximizing conservation versus intensification of traditional agriculture and expansion of hydropower capacity-in which we research, develop, and scale a high-tech innovation approach that sees the Amazon as a global public good of biological assets that can enable the creation of innovative high-value products, services, and platforms through combining advanced digital, biological, and material technologies of the Fourth Industrial Revolution in progress.Amazon tropical forests | Amazon sustainability | Amazon land use | Amazon savannization | climate change impacts

“…Therefore, this area involves great soil spatial variability, mainly regarding to soil texture which is highly related to ecological processes. It was not highlighted in previous ecological modeling studies, mainly those related to soil organic matter dynamics (Bernoux et al, 2002;Batjes and �ijk-dynamics (Bernoux et al, 2002;Batjes and �ijk-shoorn, 1999;Batjes, 2005;Cerri et al, 2007;Cochrane and Cochrane, 2006;Holmes et al, 2006;Moraes et al, 1995;Schaefer et al, 2008).…”

“…The Amazon Basin is usually regarded as homogeneous environment, having uniform wet climates, similar soils, and uniform wet forest biomes (Bernoux and Volkoff, 2006;Cerri et al, 2007). However, at subcontinental scale, it is not entirely homogenous, particularly with respect to soils.…”

Soils of a large tropical area with differentiated landscapes cannot be treated uniformly for ecological applications. We intend to develop a framework based on physiography that can be used in regional applications. The study region occupies more than 1.1 million km 2 and is located at the junction of the savanna region of Central Brazil and the Amazon forest.It includes a portion of the high sedimentary Central Brazil plateau and large areas of mostly peneplained crystalline shield on the border of the wide inner-Amazon low sedimentary plain.A first broad subdivision was made into landscape regions followed by a more detailed subdivision into soil regions. Mapping information was extracted from soil survey maps at scales of 1:250000-1:500000. Soil units were integrated within a homogenized legend using a set of selected attributes such as taxonomic term, the texture of the B horizon and the associated vegetation. For each region, a detailed inventory of the soil units with their area distribution was elaborated. Ten landscape regions and twenty-four soil regions were recognized and delineated.Soil cover of a region is normally characterized by a cluster composed of many soil units. Soil diversity is comparable in the landscape and the soil regions. Composition of the soil cover is quantitatively expressed in terms of area extension of the soil units. Such geographic divisions characterized by grouping soil units and their spatial estimates must be used for regional ecological applications.

“…O manejo correto de pastagens pode contribuir significativamente para o aumento no estoque de carbono no solo (CERRI et al, 2007;DEON, 2013), assim como a condução de sistema Agroflorestal, e lavoura em sistema plantio direto na palha (SISTI et al, 2005;BAYER et al, 2006).…”

“…A Amazônia desempenha papel importante no ciclo global do carbono, devido a sua extensão territorial e a quantidade de C armazenada tanto na vegetação, quanto no solo (CERRI et al, 2007). A Amazônia brasileira representa uma significativa parcela das florestas tropicais remanescentes do mundo (LAPOLA et al, 2014), sendo responsável por importantes serviços ambientais como a manutenção da biodiversidade, ciclagem da água, além de estocar quantidades apreciáveis de carbono na biomassa e no solo (FEARNSIDE, 2005 (ASSAD et al, 2013) e influenciar mudanças climáticas (LAPOLA et al, 2014).…”
