Intense international competition pushes the actors of wood supply chains to implement efficient wood supply chain management incorporating coordinated cost-saving strategies to remain competitive. In order to observe the effects of individual and coordinated decision making, mixed-integer programming models for forestry, round-wood transport, and the wood-based industry were developed and integrated. The models deal with operational planning issues regarding production, harvest, and transport and are solved sequentially for individual cost optimization of each wood supply chain actor as well as simultaneously by a combined model representing joint cost optimization in an integrated wood supply chain. This allows for the first time, benchmarking relative cost-saving potential of the wood procurement strategies coordinated transports, integrated supply chains, satellite stockyards, and higher truck payloads within a single case study setting. Based on case study data from southern Austria, results show the advantages of an integrated supply chain with a cost-saving potential of up to 24%. Higher truck payloads reinforce this potential and enable up to 40% savings compared to the predominant wood procurement situation in Central Europe. Wood supply chain integration for Central European circumstances seems to be feasible only for a limited consortium of a few companies, for example when restricted to a wood-buying syndicate supplying several industry plants or a few large forest enterprises, especially as both groups are commonly steering wood transport on their own. Consequently, further research on the challenging task of implementing integrated supply chains using the opportunities of digitalization to realize existing cost savings potential by deepening cooperation and intensifying information exchange is needed.

PurposeThe overall objective of this study is to holistically analyse the complexities involved in the adoption of sustainable wood supply chain in the Amazon and to develop strategic interventions to improve the system.Design/methodology/approachThis study uses the systems thinking and modelling framework that included problem structuring followed by the development of a systems model. Tumbira and Santa Helena do Inglês, two Amazonian communities, were used as a case. Data were collected by staying inside the Amazon, observing the community members and interacting with them during their activities, including logging inside the forest.FindingsA behaviour over time (BOT) graph developed as a part of problem structuring showed that deforestation of the Amazon is still increasing, despite the creation of protected areas and NGO activities in the region. Developing a sustainable wood supply chain is considered as one of the approaches for sustainable forestry in the Amazon, but its adoption is slow. The systems model captured the underlying structure of this system and explained this counterintuitive behaviour using eleven interacting feedback loops.Research limitations/implicationsThis study is confined to two Amazonian communities and recognises the limitations of generalisations.Practical implicationsThis paper illustrates the development of three strategic interventions to improve the adoption of sustainable wood supply chain in the Amazon.Originality/valueThis study highlights the real issues faced by real communities living in the Amazon for adopting sustainable supply chain management (SSCM) practices. It contributes to the literature on sustainable wood supply chain by systemically analysing the challenges in its adoption, not sufficiently discussed in the literature.

Digitalization and its associated technology are shaping the world economy and society. Data collection, data exchange, and connection throughout the wood supply chain have become increasingly important. There exist many technologies for the implementation of Industry 4.0 applications in forestry. For example, the integration of harvester production data throughout the wood supply chain seems to have strong optimization potential but it is faced with several challenges due to the high number of stakeholders involved. Therefore, the objective of this article is to analyze the legal, social, and economic conditions surrounding the integration of harvester production data integration in Germany. For analysis of the legal and economic conditions, a narrative literature analysis was performed with special consideration of the relevant German and European legal references. For determination of the social conditions, a qualitative content analysis of 27 expert interviews was performed. Results showed that legal ownership of harvester production data cannot be clearly defined in Germany, but there exist several protection rights against misuse, which can define an ownership-similar data sovereignty. Furthermore, harvester data use can be restricted in the case where personal data are traceable, based on European data protection law. From a social perspective, the stakeholders interviewed in the study had different opinions on data ownership. Stakeholders require specific criteria on the data (interfaces) and other factors for the acceptance of new structures to allow successful harvester data integration. From an economic perspective, harvester production data are tradeable through varying transaction forms but, generally, there is no accepted and valid formula in existence for calculating the value or price of harvester data. Therefore, the authors advise discussing these issues with key stakeholders to negotiate and agree on data ownership and use in order to find a suitable solution to realize optimization potentials in the German wood supply chain.

The industrial wood supply from public lands is at risk in Alberta from natural disturbances and landbase withdrawals while simultaneously being asked to provide for an increasing timber harvest rate. While maintaining the timber landbase is critical, we believe that the only truly sustainable way of increasing wood supply is by growing more wood. Meeting these wood supply goals will require the application of tree improvement and intensive silviculture programs on the best sites to increase timber productivity, reduce rotation lengths, and close timber supply gaps. In this article, we present the main ideas from a recent Canadian Institute of Forestry – Rocky Mountain Section workshop on wood supply in Alberta and provide what we see as the best path forward to meeting our wood supply goals – growing more timber.

Timber transportation is an essential and often unprofitable segment of the wood supply chain. This study evaluated the profitability of individual timber deliveries for log truck owners in the US South. Origin and destination data were collected from 909 deliveries from 257 harvest sites. Travel time and distance were estimated using ArcGIS and GPS tracking. Monte Carlo Simulation was used to calculate 1000 unique combinations of payload, harvest site turn-time, mill turn-time, and percent-loaded km, yielding a dataset of 909,000 deliveries. Hauling costs and revenues for each delivery were estimated using published estimates. Driver wages were estimated in two ways: an hourly wage of $30.60 (USD) and 30% of the gross revenue from the load being delivered. Logistic regression was used to evaluate the relationship between six dependent variables and profitability. Only 14% of deliveries were profitable when the driver was paid an hourly wage versus 42% when the driver was paid 30% of gross revenue. Deliveries with one-way haul distances between 49 and 113 km (31–70 mi) were least likely to be profitable. Many deliveries could be profitable if logging businesses and mills reduced turn-times to under 20 min at mills and 30 min at harvest sites.
