Forests have to cope with three interlinked transitions: climatic transition, energetic transition and economic transition with an up-rising demand on wood such as new needs to feed up the emerging bioeconomy. Meanwhile, forests are part of a world-wide, nature-based solution for climate warming mitigation, although forests are at the center of territorial conflicts. Thus, it is urgent to foster the development of innovative forest management practices taking into account the quadruple interaction ‘which forest resources x in which biogeoclimatic zones x with which forest managements x for which purposes’. By doing so we expect to provide decision tools for forest managers and policy makers. The French national infrastructure IN-SYLVA federates in a common organization tropical and tempered in situ experimentation networks managed by the public and private sectors (5,000 experimental trials covering 4,000ha) as well as in lab facilities (functional ecology, wood properties and genomics) and in silico resources (data bases and models). In such a way IN-SYLVA deals jointly with forest management, biogeochemical features, genetics and economy. IN-SYVA will guide public policies by scientific or technical enlightening and will be the link to the academic and professional sphere. Within the Open Science framework IN-SYVA data policy and practices will contribute to the sharing of data and knowledge. Our first practical goal is to set up an information system federating the distributed resources and providing through the IN-SYLVA data portal the necessary metadata for discovery and access to the data collected by the experimental networks< Leer menos
