abstract = "Large-scale conversion of tropical forests into pastures or annual
crops will likely lead to changes in the local microclimate of
those regions. Larger diumal fluctuations of surface tempera- ture
and humidity deficit, increased surface runoff during rainy
periods and decreased runoffduring the dry season, and decrea- sed
soil moisture are to be expected. lt is likely that
evapotranspiration will be reduced because of less available
radiative energy at the canopy leveI since grass presents a higher
albedo than forests, and also due to reduced availability of soil
moisture at the rooting zone primarily during the dry season.
Coupled numerical models of the global atmosphere and biosphere
have been used recently to assess the effects of Amazonia
deforestation on .the regional and global climate. The results of
these General Circulation Model (GCM) simulations show that, if
the tropical forests were replaced by degraded grass (pasture) in
the model, there was a significant increase in surface temperature
and a decrease in evapotranspiration, precipitation and runoff.
There was also an increase in the length of the dry season which
can have serious implications for the reestablishment of the
tropical forests in the cleared areas.",
