Dear colleagues, I have the pleasure to inform you that the session on No. 148 “Innovative value added chains in forestry” in the Congress segment: All Division 4 (Forest Assessment, Modelling and Management) Meeting for upcoming IUFRO 125th Anniversary Congress in Freiburg Germany, 19-22 September, 2017 is open for abstract submission at http://iufro2017.com/call-for-abstracts. The deadline for abstract submission is 30 November, 2016. If you want to discuss your ideas, please contact one of the organizers (see below). Session outline The value added - from harvesting, processing and using the potentials of (domestic) forest resources - to supply refined timber or non-timber products or to provide touristic or green care services, continues to increase the value of forested areas - a major part of Bio -Economy. The paradigm of the cascade usage between material and energetic usage and dividing high value from low value assortments - a particularity of forestry - is in line with the European strategy of Circular Economy for increasing resource-efficiency. Accordingly, this session aims to present outstanding case studies of innovative supply chains that foster rural-urban linkages and strengthen interdisciplinary interfaces. It will also discuss methodological approaches such as calculation schemes or the applicability of optimization and behavioral models to compute the value added for certain administrative units. Such multi-method approaches introduce interesting views for deriving a regional value added, by capturing the most relevant input-factors and outputs along the value added chain: from the supply of raw materials and the use of products - to the profit made and taxes paid. That process can consider horizontal and vertical interlinkages covering intermediate suppliers of individual actors across the production chain. Multiplier effects like that are extending the “chain concept” to a “network concept”. Therein effects of CO2 sequestration or additional value added from introducing carbon taxes could be included as well. Moreover, we welcome contributions providing insights regarding the competitiveness of regional and international value added chains or the latent conflict between microeconomic interests and macro-economic benefits as valuable inputs for the discussion. This Session situates, elaborates, and further explains the theory of value chain, with focus on interdisciplinary approach. It emphasizes crosscutting and motivations for supplementing the “buyer-driven” and “producer-driven” modes of global commodity chains in forestry. It considers horizontal and vertical interlinkages covering intermediate suppliers of individual actors across the production chains, as one of the elements of bioeconomy. The session is organised under IUFRO All Division Meeting 4 Forest Assessment, Modelling and Management, but it is not restricted to AMM and will feature interdisciplinary qualitative and quantitative research, combining ideas and framings from forestry as whole. The session is organised by researchers from different disciplines, who will also seek to include additional papers to widen the disciplinary and geographical coverage. Best regards, your contribution and looking forward to see you in Freiburg!
