The EU Bioeconomy Strategy, updated in 2018, in its Action Plan pledges an EU-wide, internationally coherent monitoring system to track economic, environmental and social progress towards a sustainable bioeconomy. This paper presents the approach taken by the European Commission's (EC) Joint Research Centre (JRC) to develop such a system. To accomplish this, we capitalise on (1) the experiences of existing indicator frameworks; (2) stakeholder knowledge and expectations; and (3) national experiences and expertise. This approach is taken to ensure coherence with other bioeconomy-related European monitoring frameworks, the usefulness for decision-making and consistency with national and international initiatives to monitor the bioeconomy. We develop a conceptual framework, based on the definition of a sustainable bioeconomy as stated in the Strategy, for a holistic analysis of the trends in the bioeconomy sectors, following the three pillars of sustainability (economy, society and environment). From this conceptual framework, we derive an implementation framework that aims to highlight the synergies and trade-offs across the five objectives of the Bioeconomy Strategy in a coherent way. The EU Bioeconomy Monitoring System will be publicly available on the web platform of the EC Knowledge Centre for Bioeconomy. ; Published

Produce wood, preserve the environment, provide social services: all these goods and services are expected of the forests nowadays. Forests can sustainably produce them, but how much? These products are joined outputs in a production process composed of forest growth and management. Therefore, it is important to characterize how outputs are joined to set production goals. In this paper, we simulate alternative management scenarios for Quercus petraea even- aged high forest at the stand scale. Then we estimate for each scenario the production of three goods and services: 1) the production of wood in terms of the net present value of an infinite series of rotations (NPVIS); 2) the preservation of biodiversity, using an indicator of the number of bird species potentially present in the forest (Bio); 3) the production of a recreation service, in terms of attractiveness for recreational activities (A). Lastly, we determine production possibility frontiers for the three two-output combinations. We show that NPVIS and Bio or NPVIS and A are substitute products of forest management, but there are possibilities for producing both in the same forest. Bio and A are compatible to a certain extent. The methodology employed seems efficient to study multi-functionality at the stand level.

Monitoring employment in the European wood-based bioeconomy requires reliable, consistent, and comparable statistics across subsectors and over time. Statistics concerning employment in wood-based industries - the main component of the forest-based bioeconomy - must be processed carefully to cope with differences in definitions and estimation methods. In addition, specific methods must be applied to estimate wood-based employment in sectors including also non-wood activities. In this study, we first delineate the boundaries of the wood-based bioeconomy, and then create a harmonised time series on employment for the identified sectors. Finally, we estimate the share of wood-based employment along the value chain in all sectors using wood. According to the results, forestry and extended wood-based value chains employed 4.5 million people in the EU-28 in 2018. Employment in wood-based value chains decreased between 2008 and 2013 in the aftermaths of the financial crisis. Continuously decreasing employment - most apparent in the manufacture of solid wood products and pulp and paper - results from increasing productivity and a decreasing demand for graphic paper. Further, most of the wood-based employment in the EU takes place in downstream parts of value chains, although the weight of the primary sector is still high in some Eastern European countries.

The EU Water Framework Directive aims to ensure restoration of Europe's water bodies to "good ecological status" by 2027. Many Member States will struggle to meet this target, with around half of EU river catchments currently reporting below standard water quality. Diffuse pollution from agriculture represents a major pressure, affecting over 90% of river basins. Accumulating evidence shows that recent improvements to agricultural practices are benefiting water quality but in many cases will be insufficient to achieve WFD objectives. There is growing support for land use change to help bridge the gap, with a particular focus on targeted tree planting to intercept and reduce the delivery of diffuse pollutants to water. This form of integrated catchment management offers multiple benefits to society but a significant cost to landowners and managers. New economic instruments, in combination with spatial targeting, need to be developed to ensure cost effective solutions – including tree planting for water benefits - are realised. Payments for Ecosystem Services (PES) are flexible, incentive-based mechanisms that could play an important role in promoting land use change to deliver water quality targets. The PESFOR-W COST Action will consolidate learning from existing woodlands for water PES schemes in Europe and help standardize approaches to evaluating the environmental effectiveness and cost-effectiveness of woodland measures. It will also create a European network through which PES schemes can be facilitated, extended and improved, for example by incorporating other ecosystem services linking with aims of the wider forests-carbon policy nexus.
