Impacts of harvest reductions on the value-added wood chain – the case of Austria Wooden biomass availability and the possibility of a scarcity due to a potential harvest reduction are of crucial importance to the Austrian forest-based sector but also relevant for decision makers in environmental policy. The simulation model of the Austrian forest-based sector (model: “Forst- und Holzwirtschaft”, FOHOW) was used to simulate two independent scenarios with harvest reduction in forests available for wood supply (FAWS). In one scenario the reductions are implemented on FAWS of “average” profitability, in the other scenario the reductions take place on FAWS with “poor” profitability. On the one hand, the aim of the study was the analysis of the impacts of reduced wood supply on the value-added wood chain until 2025, on the other hand the impact intensities of the two scenarios have been compared. In general, a harvest reduction resulting in less wood supply has a negative impact on the Austrian forest-based sector. While forestry and the sawmill industry suffer more from a harvest reduction in FAWS with average profitability (because of the lower supply of coniferous roundwood), a harvest reduction in FAWS with lower profitability would affect the panel and paper industry as well as the wood-based energy sector more negatively; reduced harvests in these forest areas would mainly reduce the supply of non-coniferous wood. This, in turn would fuel the competition between the use of wood for materials vs. energy and push pulp- and fuelwood prices up.
