Abstract
Geographic Information Systems (GIS) are used for the precise quantification of forest biomass to plan its sustainable energy use. This study aimed to provide a comprehensive tool for inventorying areas covered by Dichrostachys cinerea (marabou) in the municipality of Camagüey, facilitating the selection of cost-effective and environmentally responsible technologies and machinery systems. A comprehensive technological characterization was carried out using a standardized digital cartographic base and GIS with QGIS software. The methodology included delineating the effective marabou area using remote sensing, classifying it into diameter categories (fine and medium), and evaluating variables such as rockiness, slope, and land tenure. The results determined that the effective marabou area was 6310.45 hectares, dominated by the "medium" category (3517.41 ha), which was found mainly on relatively flat, relatively unrocked soils. The largest share of land ownership with this coverage corresponded to Credit and Service Cooperatives (CCS) and Agricultural Production Cooperatives (CPA), with an available biomass of 137,284.31 tons. It was concluded that the methodology employed guarantees a high-quality inventory and justifies the selection of semi-mechanized technologies for the energy use of biomass, and is also applicable to other forest inventories.
