study proposes a quantitative environmental assessment method. Economic
consequences related to forest operations in Pinus radiata D. Don
forests, under the concept of soil and water sustainable natural
capital were modeled. Environmental costs consider the costs of
mitigation actions required to reduce impact levels up to the impacts
caused by the use of the best available technology.
model applies a standard costs matrix to an impact coefficient matrix
according to the level of sensitivity of the soil. The result is
a valuation of environmental costs in monetary units per hectare.
The model allows impartial assessment at company , regional and
scenarios and technologic appropriateness levels were simulated.
Environmental costs range from 2246 US$/ha (5.61 US$/m³) to
1019 US$/ha (2.55 US$/m³) for both the use of inappropriate
technology in traditional harvesting and the use of the best techniques
in mechanized harvesting, respectively. Relating environmental costs
with the annual harvesting rate of Pinus radiata D. Don forests
in Chile at high and moderate appropriateness levels, figures of
30 to 50 millon US dollars per year were obtained.
impacts are related ro road construction, the use of prescribed
fire for soil preparation practices and ground based logging on
wet soil conditions.
