Changement climatique : la biodiversité forestière à la croisée des enjeux de conservation et d’atténuation / Christophe Bouget in Sciences eaux & territoires, n°33 (Année 2020)
[article]
Titre : Changement climatique : la biodiversité forestière à la croisée des enjeux de conservation et d’atténuation Type de document : Livre Auteurs : Christophe Bouget, Auteur ; Marion Gosselin, Auteur ; Fabien Laroche, Auteur Année de publication : 2020 Article en page(s) : pp. 84-89 Langues : Français Mots-clés : stratégie de séquestration de carbone conservation de la biodiversité changement climatique Résumé : "On peut distinguer différentes stratégies de séquestration de carbone par la filière bois-forêt : celles fondées sur la volonté d’augmenter le stock de carbone contenu dans les forêts et celles fondées sur la volonté d’exporter rapidement du carbone des forêts gérées vers d’autres compartiments d’utilisation durable du bois comme le bois-énergie ou le bois de construction. Ces différentes stratégies de séquestration et leur combinaison, vouées à augmenter la fonction de puits de carbone des forêts, sont-elles favorables ou antagonistes à la conservation de la biodiversité ? Dans cet article, les auteurs font le point sur le sujet, en explorant de façon fine les potentiels d’antagonismes et de synergies entre conservation de la biodiversité et atténuation du changement climatique."

Titre : The loss of biodiversity conservation in EU research programmes: Thematic shifts in biodiversity wording in the environment themes of EU research programmes FP7 and Horizon 2020 Type de document : Livre Auteurs : J.F. Admiraal, Auteur ; C.J.M. Musters, Auteur ; G.R. (de) Snoo, Auteur Année de publication : 2016 Article en page(s) : pp. 12-18 Langues : Anglais Catégories : [ZG] Europe Mots-clés : conservation de la biodiversité évaluation économique service écosystémique politique environnementale Commission européenne Résumé : "Society has been seeking ways to express biodiversity's value to stimulate its protection. Economic valuation of ecosystem services has had limited success to motivate biodiversity protection and reaching the EU 2020 biodiversity strategy targets is in danger of failure. The expression of biodiversity's value in policy documents thus becomes a topic of discussion, because it greatly influences the ways policy makers think about environmental problems. We present an analysis of the word use related to biodiversity conservation versus ecosystem services in the environment themes of the FP7 and Horizon 2020 research work programs of the European Commission in the period of 2007–2014, and the projects accepted under these themes. We conclude first that biodiversity was lost as a topic in the transition from FP7 to Horizon 2020, accompanied by a three-quarters loss of biodiversity topics in the projects accepted under these research work programs. Moreover, the use of ‘ecosystem services’ was 1.5 times higher at the end of that period compared to the beginning in the research work programs, to the detriment of the use of ‘sustainability’ and ‘conservation’ which halved during that same period. In the light of international commitments to biodiversity conservation, the focus toward ecosystem services and away from conservation is of great concern."

Titre : A framework for the classification Chilean terrestrial ecosystems as a tool for achieving global conservation targets Type de document : Livre Auteurs : Karina Martïnez-Tilleria, Auteur ; Mariela Núñez-Ávila, Auteur ; Carolina León, Auteur ; Patricio Pliscoff, Auteur ; Francisco Squeo, Auteur ; Juan Armesto, Auteur Année de publication : 2017 Article en page(s) : pp. 2857-2876 Langues : Anglais Mots-clés : gestion écosystémique conservation de la biodiversité trait fonctionnel aire protégée Résumé : "Countries that are signatories of the Convention of Biological Diversity are committed to the goal of protecting 17% of their natural ecosystems by 2020. The lack of an up-to-date, operational classification and cartography of regional ecosystems seriously limits the assessment of progress towards this goal. Here, we present a broad ecosystem framework, which combines land use, functional traits of dominant plant species, and climatic factors for the classification of terrestrial ecosystems and apply this framework to classify Chilean terrestrial ecosystems. This new classification is consistent with the recently proposed IUCN framework to assess ecosystem conservation status. Using this framework, we identified and described 30 Chilean terrestrial ecosystems, including land units of natural and anthropogenic origin. We also provide a cartographic representation of ecosystems for land planning purposes and an overall assessment of their conservation status. We evaluated the representation of the 30 ecosystems in the Chilean National System of Protected Areas (NSPA) and in Private Protected Areas (PPA), identifying 15 ecosystems underrepresented (below the 17% target) in the NSPA, in contrast to only 11 when the area of NSPA+PPA was considered. The proposed classification can be broadly applicable to assess the conservation status of ecosystems elsewhere, using similar conceptual and methodological tools. The development of functional ecosystem classifications for different countries must be encouraged to facilitate monitoring of global conservation targets."

[Thèmes] Natura 2000Mots-clés : biodiversité conservation de la biodiversité modèle de distribution des espèces (SDM) plante invasive Résumé : "Local species distribution models (SDMs) were constructed for three of the most harmful invasive alien plant species (Fallopia spp., Solidago spp. and Heracleum mantegazzianum) in the Koko?ínsko Protected Landscape Area (Czech Republic), using Natura 2000 habitat types and other environmental conditions as predictors for the SDMs. Presence or absence data (recorded by field mapping) was entered into the SDMs and used to predict the potential distribution of particular species. Here, we critically evaluate the accuracy of the models and assess their applicability for natural resource protection. Variables such as habitat and soil type tend to dictate the current distribution of Solidago spp., while distance from roads and water corridors and elevation are important for Fallopia spp. distribution. For Solidago spp., ‘generalised boosted models’ and ‘generalised additive models’ were considered the most suitable algorithms. For Fallopia spp., however, the predictive power of the models tended to be weak, while the number of localities was too low for SDMs in the case of H. mantegazzianum. The number of initial localities containing invasive alien species was an important factor for making significant predictions of potential distribution. In general, the predictive power of the models was too low when using less than 10 localities; for good predictive power at the local scale, we suggest that at least 100 localities/100 km2 are used."
