Fig. 7.12 The land surface properties in Brazilian Amazon. Only forests and water bodies are
showed in the land cover layer (1 km 9 1 km, USGS land cover classification). Grid cells in
which forests are converted into the pasture (yellow) and woodland (darkgreen) are provided in
the land surface change layer (0.58 9 0.58). The study area (red rectangle) covers most changed
forest land cells
sensible heat flux, latent heat flux, precipitation, and temperature in two experi-
ments are simulated and processed into annual domain-averaged variables during
the simulation period of 2090-2100.
7.3.2 Results and Discussion
7.3.2.1 Future land Surface Properties
In the Brazilian Amazon, the entire forest accounts for 78.07 % of the total area in
the year 2005, totally contributed by the evergreen broadleaf forest. According to
the statistical analysis, the projected deforested land occupies 18.23 % of the study
area during the period from 2005 to 2100. The ratio of cells, in which forest is
converted into pasture and woodland, to the total grid cells in the study area is 5.12
and 13.11 %, respectively. Specifically, the primary forest degrades by 13.36 % of
