Case of La Palma agroforestry enterprise, Pinar del Río. Rev cubana ciencias forestales [online]. 2021, vol.9, n.3, pp. 440-453.  Epub 09-Set-2021. ISSN 2310-3469.

The use of forest biomass for energy production represents one of the current alternatives considered by the country for its energy development. However, not all the information on the real potential of this resource is available at the enterprise level, which limits the timely planning of its management and sustainable use. The present work contributes to solve this situation by developing a methodology for the zoning and evaluation of the potential of residual forest biomass for energy purposes at the enterprise level. This methodology integrates data, management restriction criteria, results of previous research and Geographic Information System tools, which allows processing, analyzing and updating information on forest areas and their energy potential, based on data generated by forest management. The validation of the methodology, in its three stages, is carried out in the agroforestry enterprise La Palma, province of Pinar del Río. Seventy-six percent of the areas with a viable harvesting index are determined, 54.27 % of which are classified as very high, 0.35 % as high and 12.14 % as medium, with an annual residual forest biomass potential of 82,048.94 tons and an energy potential of 22,205 tons of oil equivalent. Three zones of high potential for energy purposes are defined: north and south of the Unidad Empresarial de Base Viñales, and the southern part of La Jagua. The results of the validation of the methodology show its viability, relevance and novelty for the company's economic, environmental and social management.
