Framework Proposal to Quantify the Contribution of Non-Wood Forest Products to the European Union Forest-Based Bioeconomy

Forest ecosystems provide numerous services that contribute to the wellbeing of societies. However, the lack of knowledge about the benefits of non-wood forest ecosystem services, such as non-wood forest products (NWFPs), hinders efficient forest policy decision-making processes. This study proposes a new extension of the Social Accounting Matrices (SAMs) to capture both the private and the social component of NWFPs. By means of a literature review, we show how extended SAMs can be a suitable approach to explain the causal relationship between the supply of forest ecosystem services, forest-based value chains, and the European bioeconomy. The literature analysis shows that the number of research studies calibrating or using SAMs has been increasing over the last decades. Recent extensions of the SAMs made it possible to evaluate the relationship between human wellbeing and the environment. Moreover, we found applications to the forest sector (limited to timber) and to the supply of some non-wood ecosystem services. We believe the extended SAMs will support decision-makers to design forest strategies that properly account for the benefits NWFPs provide to both the economy and the society.
