abstract = "Field observations and numerical studies revealed that large scale
deforestation in Amazonia could alter the regional climate
significantly, projecting a warmer and somewhat drier
post-deforestation climate. In this study we employed the
CPTEC-INPE AGCM to assess the effects of Amazonian deforestation
on the regional climate, using simulated land cover maps from a
business-as-usual scenario of future deforestation in which the
rainforest was gradually replaced by degraded pasture or by
soybean cropland. The results for eastern Amazonia, where changes
in land cover are expected to be larger, show increase in
near-surface air temperature, and decrease in evapotranspiration
and precipitation, which occurs mainly during the dry season. The
relationship between precipitation and deforestation shows an
accelerating decrease of rainfall for increasing deforestation for
both classes of land use conversions. Continued expansion of
cropland in Amazonia is possible and may have important
consequences for the sustainability of the regions remaining
natural vegetation.",
