| We develop a model for estimating the environmental asset (EA) value of a selection of forest provisioning services that include timber, cork, firewood, pine-nuts and grazing resources and carbon sequestration as a regulating ecosystem service. This EA computing model is applied to a group of 567 silvopastoral farms in Andalusia (Spain). The expected stream of the provisioning and regulating ecosystem services is estimated at farm level for the six main forest species in this region, as well as, for treeless scrublands and grasslands. The model allows anticipating potential threats to forest conservation due to the lack of profitability for continuing forestry activity; and the minimum compensations to make forest conservation an efficient investment alternative. The results of this research highlight the spatial variability on EA estimations. Geographic and biophysical conditions, such as slope gradient, forest structure and sites productivity, play an important role in drawing the spatial variation of EA values. The assumption regarding discount rates and prices have a significant effect on EA figures and for predicting potential forest conservation problems | |
