abstract = "The Amazon hosts one of the largest stocks of arable land in the
world. However, little is known about the available extent of
agricultural land in conformity with legal, agronomical and
environmental requirements. This study aims to identify and
quantify potentially available areas for agricultural expansion in
the Brazilian Amazon considering the extent of: (i) legally
available forested lands, (ii) previously converted lands with
suitable productive capacity and (iii) previously converted lands
free of land use conflicts. This analysis was carried out by
integrating georeferenced information on land use, soil fertility,
terrain slope, biomass, protected areas and land use policies
(e.g. Brazilian Forest Code) into a conditional decision support
procedure, based on Boolean inference techniques. Our results
showed that 11.69% (493,103.03 km2) of the Brazilian Amazon would
be potentially available for agricultural expansion in the year
2010. This area was essentially dominated by forests (59.37%),
followed by previously converted lands (40.63%). The extent of
this area was equivalent to 75.86% of the total cultivated area in
Brazil in 2010. However, the effective usage of these areas would
have direct political and environmental implications. First, it is
expected that the effective usage of available forests would
detract recent achievements of the Brazilian Action Plan for
Prevention and Control of Deforestation in the Amazon, which has
reduced deforestation by 79% from historical rates. Moreover, the
conversion of these areas could result in a committed emission of
13 ± 1 Pg CO2eq to the atmosphere which is equivalent to the total
emissions from land cover change registered in Brazil during the
20002010 period. Therefore, the compensation of environmental
liabilities stands as the most consistent destination for the
available forests mapped in this study. To minimize environmental
impacts, agricultural expansion in the Brazilian Amazon should be
restricted to already converted areas. This land cover class
totalizes 200,000 km2, which could support agricultural expansion
without promoting the advance of deforestation.",
