Determination of gross and net land area for establishment of forest plantations for energy based on geographic information system at Ranco province in Chile
Alvarez Ocares, Cristian Adolfo
In the last years the current energy crisis in Chile has led to consider different sources of renewable energy, where forest biomass from fast growing plantations play a important role. The aim of this study was to find suitable land areas (gross and net) for the establishment of wood energy plantations in Ranco province in Chile, following the methodology proposed in the thesis of forest engineer Federico Anderfuhren, where different criteria and restrictions were set using as a tool geographic information system (GIS). The results showed a suitable gross area of 141.889 ha (17%) and a net area of 46.350 ha (6%) of the province. It was conclude that the coverages with the greatest influence obtaining the gross area were water bodies and protected native forest and obtaining the net area, land use capacity (II, III, VII and VIII) and erosion land potential.
