    Description: Driven by the growing awareness of the finite nature of fossil raw materials and the need for sustainable pathways of industrial production, the bio-based economy is expected to expand worldwide. Policy strategies such as the European Union Bioeconomy Strategy and national bioeconomy strategies foster this process. Besides the advantages promised by a transition towards a sustainable bioeconomy, these processes have to cope with significant uncertainties as many influencing factors play a role, such as climate change, technological and economic development, sustainability risks, dynamic consumption patterns and policy and governance issues. Based on a literature review and an expert survey, we identify influence factors for the future development of a wood-based bioeconomy in Germany. Four scenarios are generated based on different assumptions about the development of relevant influence factors. We discuss what developments in politics, industry and society have a central impact on shaping alternative futures. As such, the paper provides a knowledge base and orientation for decision makers and practitioners, and contributes to the scientific discussion on how the bioeconomy could develop. We conclude that the wood-based bioeconomy has a certain potential to develop further, if adequate political framework conditions are implemented and meet voter support, if consumers exhibit an enhanced willingness to pay for bio-based products, and if among companies, a chance-oriented advocacy coalition of bioeconomy supporters dominates over proponents of fossil pathways.

    Description: In present-day Earth system models, the coupling of land surface and atmosphere is based on simplistic assumptions. Often the heterogeneous land surface is represented by a set of effective parameters valid for an entire model grid box. Other models assume that the surface fluxes become horizontally homogeneous at the lowest atmospheric model level. For heterogeneity above a certain horizontal length scale this is not the case, resulting in spatial subgrid-scale variability in the fluxes and in the state of the atmosphere. The Max Planck Institute for Meteorology’s Earth System Model is used with three different coupling schemes to assess the importance of the representation of spatial heterogeneity at the land surface as well as within the atmosphere. Simulations show that the land surface–atmosphere coupling distinctly influences the simulated near-surface processes with respect to different land-cover types. The representation of heterogeneity also has a distinct impact on the simulated gridbox mean state and fluxes in a large fraction of land surface.
