abstract = "The existence of multiple climate-vegetation equilibria in
Tropical South America is investigated under present-day climate
conditions with the use of an atmospheric general circulation
model coupled to a potential vegetation model. Two stable
equilibria were found. One corresponds to the current biome
distribution. The second is a new equilibrium state: savannas
replace eastern Amazonian forests and a semi-desert area appears
in the driest portion of Northeast Brazil. If sustainable
development and conservation policies were not able to halt the
increasing environmental degradation in those areas, then land use
changes could, per se, tip the climate-vegetation system towards
this new alternative drier stable equilibrium state, with
savannization of parts of Amazonia and desertification of the
driest area of Northeast Brazil, and with potential adverse
impacts on the rich species diversity in the former region and
water resources in the latter.",
