We demonstrate its usefulness for extracting bio-molecules contained in silver fir growing in France. Context : Numerous bio-active molecules can be extracted from trees at an industrial scale. Supply chain actors play a central role in this emerging bio-economy. However, they do not have enough information and tools to make informed decisions with respect to species, growing locations, or identities of potential suppliers of relevant wood biomass. Aims : We explore and demonstrate an information chain and methodological framework that can help make three critical decisions regarding the selection of (1) the species containing the desired bio-molecules, (2) the locations where the resource is collected, and (3) the supply chain partners and types of industrial wood by-products necessary to obtain sufficient biomass for industrial extraction. Methods : The methodological framework provides detailed guidelines and references to select the right combination of sampling protocol, allometric models, chemical analyses, GIS tools, and forest growth and supply chain models in order to produce information for the three decision steps within various regional contexts. Results : We apply the framework within the context of supply chain actors who are interested in estimating the quantity and diversity of bio-molecules contained in silver fir (Abies alba Mill.) growing in the Grand Est region of France. We show how conflicting environmental, legal and economic constraints can affect the results. We discuss future challenges that need to be tackled to improve the methodological framework. Conclusion : This study represents a highly detailed overview of the potential bio-molecules contained in a tree species, from its natural habitat or plantation to the end of the regional supply chain. It also represents a step towards the development of a generic knowledge infrastructure and methodology that is necessary to solve various decision-making problems regarding the industrial supply and extraction of high-value bio-molecules.

The Loop Effect: how climate change impacts the mitigation potential of the French forest sector / Philippe Delacote in Journal of Forest Economics, vol 36 n° 3 ([01/06/2021])  

Public [article]  inJournal of Forest Economics > vol 36 n° 3 [01/06/2021] . - pp 201 - 264 Titre : The Loop Effect: how climate change impacts the mitigation potential of the French forest sector Type de document : Article/Communication Auteurs : Philippe Delacote, Auteur ; Antonello Lobianco, Auteur ; Sylvain Caurla, Auteur ; Jean-Daniel Bontemps , Auteur ; Anna Lungarska, Auteur ; Pierre Mérian , Auteur ; Miguel Rivière, Auteur ; Ahmed Barkaoui, Auteur Année de publication : 2021 Projets : 2-Pas d'info accessible - article non ouvert / Article en page(s) : pp 201 - 264 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] changement climatique [Termes IGN] dioxyde de carbone [Termes IGN] économie forestière [Termes IGN] industrie forestière [Termes IGN] modèle numérique [Vedettes matières IGN] Economie forestière Résumé : (auteur) Objectives: Evaluate the capacity of temperate forest resources to both provide climate change mitigation and to sustain the downstream timber sector explicitly considering the cascade of biophysical and economic drivers (in particular, climate change impacts and subsequent adaptation actions) and their uncertainty. Methodology: A recursive bio-economic model of French forest resources, management, and timber markets has been coupled for this study with spatial statistical models of forest response to climate change long-term scenarios and land-use change. Main Results: (a) Climate change impacts on tree mortality are greater than those on tree growth variations; (b) Due to increasing competition with agriculture, climate change may reverse current trends in forest area expansion; (c) Due to rising average tree sizes, volume growth strongly declines over time and may eventually cease within the next century; (d) Future climate change impacts already have strong consequences on today’s forest investment profitability; (e) The relative importance of forest substitution over forest sequestration increases as the timeframe increases; (f) While the forest sector has the potential to counterbalance a significant share of the national carbon emissions, this potential is threatened by climate change and the need to adapt to it. Profit-driven forest management does increase mitigation; (g) Uncertainty derived from using different climatic models over the same IPCC storyline has the same order of magnitude as the uncertainty derived from using the same climatic model under different storylines.

The effect of stumpage prices on large-area forest growth forecasts based on socio-ecological models / Mathieu Fortin in Forestry, an international journal of forest research, vol 92 n° 3 (July 2019)

However, in terms of modelling, the social aspect has been given far less attention than the ecological aspect. In this study, we modelled the impact of economic and social factors on the occurrence of harvesting. This harvest model was then integrated into an individual-based model of forest growth designed for large-area forecasts. The resulting socio-ecological model was then used to produce volume predictions for two regions of France. Among the economic factors, the annual stumpage prices in interaction with the species proved to be a significant predictor of harvest occurrence. Simulating different stumpage price evolutions made it possible to predict supply curves for the two regions. Projections until 2060 showed that increases in stumpage prices will be detrimental to standing volumes in both regions. Integrating the demand for wood products into such socio-ecological models in forestry would be a major improvement.

La filiera foresta-legno francese tra potenziale di mitigazione dei cambiamenti climatici e necessità di adattamento / Philippe Delacote in Agriregionieuropa, anno 14 n° 54 (2018)

Un modèle bioéconomique intégré de la chaîne d'approvisionnement forêt-bois est utilisé, paramétré sur la réalité forestière française, et capable de prendre en compte de manière explicite la cascade de facteurs biophysiques et économiques du changement climatique (à savoir les impacts biophysiques du changement climatique et les mesures d'adaptation qui en résultent au niveau de la gestion) ainsi que leur incertitude. Les résultats du modèle ont d'importantes implications en termes de gestion et de politique forestière, tout d'abord parce qu'ils mettent en évidence le fait que les impacts du changement climatique ont déjà de lourdes conséquences sur la rentabilité des investissements forestiers. En outre, alors que le secteur forestier est en mesure de compenser une part importante des émissions de carbone nationales, ce potentiel est en partie menacé par le changement climatique lui-même et par la nécessité de s'y adapter.

Large-scale dynamics of a heterogeneous forest resource are driven jointly by geographically varying growth conditions, tree species composition and stand structure / Holger Wernsdörfer in Annals of Forest Science, Vol 69 n° 7 (October 2012)  

Public [article]  inAnnals of Forest Science > Vol 69 n° 7 (October 2012) . - pp 829 - 844 Titre : Large-scale dynamics of a heterogeneous forest resource are driven jointly by geographically varying growth conditions, tree species composition and stand structure Type de document : Article/Communication Auteurs : Holger Wernsdörfer, Auteur ; Antoine Colin , Auteur ; Jean-Daniel Bontemps , Auteur ; Hélène Chevalier, Auteur ; Gérôme Pignard, Auteur ; Sylvain Caurla, Auteur ; Jean-Michel Leban , Auteur ; Jean-Christophe Hervé (1961-2017) , Auteur ; Meriem Fournier, Auteur Année de publication : 2012 Article en page(s) : pp 829 - 844 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Statistiques [Termes IGN] composition floristique [Termes IGN] croissance des arbres [Termes IGN] espèce végétale [Termes IGN] gestion forestière durable [Termes IGN] grande échelle [Termes IGN] inventaire forestier national (données France) [Termes IGN] strate végétale Résumé : (auteur) Context: Forest resource projections are required as part of an appropriate framework for sustainable forest management. Suitable large-scale projection models are usually based on national forest inventory (NFI) data. However, sound projections are difficult to make for heterogeneous resources as they vary greatly with respect to the factors that are assumed to drive forest dynamics on a large spatial scale, e.g. geographically varying growth conditions (here represented by NFI regions), tree species composition (here broadleaf-dominated, conifer-dominated and broadleaf-conifer mixed stands) and stand structure (here high forest, coppice forest and high-coppice forest mixture). Question and objective: Our question was how does the variance of forest dynamics parameters (i.e. growth, felling and mortality, and recruitment processes) and that of 20-year forest resource projections partition between these factors (NFI region, tree species composition and stand structure), including their interactions. Our objective was to capitalise on the suitability of an existing multi-strata, diameter class matrix model for the purposes of making projections for the highly heterogeneous French forest resource. Methods: The model was newly calibrated for the entire territory of metropolitan France based on most recent NFI data, i.e. for years 2006–2008. The forest resource was divided into strata by crossing the factors NFI region, tree species composition and stand structure. The variance partitioning of the parameters and projections was assessed based on a model sensitivity analysis. Results: Growth, felling and mortality varied mainly with NFI region and species composition. Recruitment varied mainly with NFI region and stand structure. All three factors caused variations in resource projections, but with unequal intensities. Factor impacts included first order and interaction effects. Conclusions: We found, by considering both first order and interaction effects, that NFI region, species composition and stand structure are ecologically relevant factors that jointly drive the dynamics of a heterogeneous forest resource. Their impacts, in our study, varied depending on the forest dynamics process under consideration. Recruitment would appear to have a particularly great impact on resource changes over time.
