Comparing environmental impacts of different forest management scenarios for maritime pine biomass production in France

Résumé

Forest activities are receiving special attention in recent years concerning the quantification of their environmental profiles in order to be competitive. This study aims to evaluate the environmental profile of the production of maritime pine (Pinus pinaster Ait.) biomass in France under two different management scenarios (an intensive scenario: IMS and an extensive one: EMS), representative of the real practices in the country. Life Cycle Assessment (LCA) methodology was applied to evaluate the environmental loads from a cradle-to-gate perspective. According to the results, the choice of the best management scenario will depend on the impact category considered. Thus, IMS has lower fuel requirements and it is the best option in categories directly related to fuel consumption by forest machineries, such as abiotic resources depletion, cumulative energy demand, global warming potential and photochemical oxidants formation. On the contrary, EMS will be preferred in terms of acidification and eutrophication potentials with reductions of up to 26%. The reason behind these reductions is based on the fact that these categories are considerably affected by the fertilizing process, which is not conducted under extensive conditions. Regardless the scenario, the logging stage and specially, the final cutting process, can be considered as the main environmental key factors, playing a major role in all categories. Both the production of the triple superphosphate and pruning processes play leading roles in the IMS and EMS, respectively. The comparison of these environmental profiles with those corresponding to maritime pine in Portugal highlights that the differences observed between both scenarios are related to the intensity of the forest practices as well as the biomass yield.
