Evaluation of forestry strategies for climate change mitigation in continental France. Scientific literature and main actors' positioning review

Creators

Description

This work contributes to the current scientific debate regarding the optimization of the forest sector's contribution to mitigating climate change. A scientific literature review has pointed out some uncertainties on the contribution to emission reduction objectives in the short to medium-term of an increasing harvest of forest resources for wood construction and energy generation. Timing of mitigation benefits for a managed forest depends on forestry upstream characteristics(forest and soil type and silviculture method) and downstream characteristics (transport distance, use of wood, efficiency of wood based energy production, fossil-fuel based reference system that is substituted,etc). A survey conducted among national forest experts points out debates concerning optimal silviculture practices to mitigating climate change. These discussions are due to the trades-off between sequestering carbon in forest ecosystems and climatic benefits obtained by sustainable forest harvesting and use of wood products to displace fossil emissions.

Abstract (French)

Ce travail s'inscrit dans le debat scientifique actuel autour de l'optimisation de la contribution du secteur forestier a l'attenuation du changement climatique. Une revue de la litterature scientifique nous a permis de constater l'existence d'incertitudes quant a la contribution a la reduction d'emissions a court et moyen terme d'une mobilisation accrue du bois en foret metropolitaine pour la construction, l'habitat ou pour la generation d'energie. L'horizon de temps a partir duquel les scenarios d'intensification du niveau de prelevement commencent a generer des benefices en terme de reduction de gaz a effet de serre est tres variable selon les caracteristiques de la filiere en amont (type de foret et du sol, age de coupe, type de coupe, etc.) et en aval (distance du transport, usages du bois, l'efficience du produit bois energie, l'intensite GES du materiau remplace par le bois ou de l'energie fossile remplacee par le bois energie, etc.). Une enquete menee aupres des experts nationaux du secteur forestier nous a permis de constater que les pratiques sylvicoles optimales vis-a-vis du changement climatique font l'objet de debats et qu'elles peuvent etre completement opposees dans l'arbitrage entre la capitalisation du carbone dans les ecosystemes forestiers et la maximisation de la recolte afin de se substituer aux autres combustibles fossiles ou materiaux energetivores.
