A model for the sustainable energy use of forest biomass resources in Sardinia

This study analyses the extent and spatial distribution of the forest resources and their energy potential in the province of Nuoro (Sardinia, Italy). The aim is to create a data base which will help decision makers to make a plan for the sustainable use of the resources of the territory. A GIS-based model was used to assess the energy capacity and suitability of the area. This model used four basic information layers: (1) slope, (2) hydro-geological constraints, (3) protected areas, (4) forest districts under regional forest management. These four criteria are of great importance when attempting to assess the quantity of available sustainable biomass. Based on their potential energy production, 140 basins were identified, which could provide enough forest biomass to fuel all the heating systems currently installed in public buildings of the Provincial administration.
