Simulations
In the simulations the effect of different carbon-prices and/or incentives, for keeping
forest, have been tested. The simulation period started in the year 2000 and ends in
2100. The decision, whether deforestation takes place or not and how fast it goes on,
was done in 1-year time steps. Scenario drivers, available on coarser time resolution
(e.g., population density), have been interpolated linearly between the given years.
Outputs of the simulations are trajectoria of forest cover, changes in carbon stocks
of forests, and fi nancial resources required to cut emissions from deforestation under
varying scenario assumptions.
Data
The model uses several sources of input data some available for each grid, some by
country aggregates and others are global. The data supporting the values in Table 2 are
known for each grid. Some of the values are also available for time series.

Beside the datasets, available at grid level, the PPP (World Bank, 2005) from
1975-2003, the discount rates (Benítez et al., 2004) for 2004, the corruption in 2005
(Kaufmann et al., 2005) and the fraction of long living products for the time span
2000-2005 (FAO, 2005) are available for each country (Table 3).
