“…In our analyses, only the biological production potentials of NWFPs were used because of insufficient experience calculating the economic value of, and consequently economic trade-offs among, NWFPs. Examples of the first attempts to also include the economic value of NWFPs in the optimization of multi-product management of boreal forests have been presented by Miina et al [7] for berries and Tahvanainen et al [10] for mushrooms. In the same way as already done with berries and mushrooms, the economic value of harvestable yields of other NWFPs could be calculated by using the market prices and harvesting costs.…”

“…Including the incomes from NWFPs in NPV would have resulted in forest management that is more profitable for the joint-production of NWFPs and timber. At a stand level, increasing the incomes through the sales of harvested NWFPs is a rational option for forest owners [5][6][7][8]10]. In future studies, not only the economic value of timber, but also that of NWFPs, should be included in the analysis of the synergies and trade-offs of the production of NWFPs in boreal forests.…”

“…As a result, there have been efforts to develop yield models for different NWFPs and link them in forest simulators (see, e.g., Kurttila and Tahvanainen [4] for a European review). Earlier studies indicate that valuing NWFPs can increase the profitability of stand management and modify the timber-oriented forest management for promoting NWFPs [5][6][7][8][9][10]. For example, according to Palahí et al [5], the additional incomes from mushroom picking made the management of Pinus sylvestris L. and P. nigra Arn.…”

“…In Mediterranean Pinus pinea L. stands, optimizing the production of timber and edible pine seeds simultaneously resulted in delayed thinnings [8]. Tahvanainen et al [10] observed that the production of timber and marketed mushrooms in Picea abies (L.) Karst. stands in eastern Finland was mostly in synergy, with mushroom harvesting creating significant additional incomes from forests.…”

The global growth of the consumption of non-wood forest products (NWFPs) is evident due to the current trends in lifestyle and consumption. Alongside the increased popularity and commercial use of NWFPs, their yields are also more often taken into account in forest management planning. Empirical yield models recently developed for different NWFPs enable forest managers to include their predicted yields in multi-objective optimization. However, knowledge on the synergies and trade-offs between timber production and different NWFPs is scanty. In this study, we analyzed these relationships through correlation matrices and production possibility frontiers in two case study forest holdings from Finland. A large number of Pareto optimal forest holding level plans were produced by multi-objective optimization and used to analyze trade-offs and synergies. Empirical yield models for 12 NWFPs, representing different berries, mushrooms, and tree-based products, were utilized in the analyses. The results revealed synergies and possibilities for joint-production for NWFPs, but also trade-offs between NWFPs and timber production. NWFPs often had a negative correlation with cutting removals, with the only exception being cowberry. Despite the overall negative correlation, the maximum yields of NWFPs called for some cuttings. Negative correlations with the net present value of timber production were weaker. The results are valuable when the aim is to diversify the use of boreal forests and open avenues for truly multi-objective decision support services to facilitate the decision making of forest owners.

“…Multi-functional forest planning calculations were undertaken, for instance, for mushrooms in Spain [13,14,60], Turkey [62,63] and Finland [61,64], pine honey in Turkey [57], understory berries in Finland [54,64,79,80,84], as well as cork [68][69][70][71][72] and pine nuts [74][75][76][77] in Spain and Portugal. In almost all cases, the production of timber and NTFPs (e.g.…”

Purpose of Review The increased popularity and commercial use of non-timber forest products (NTFPs) calls for the development of models for NTFPs to include their predicted yields in forest management planning and to evaluate the potential of multi-functional forest management. This study assesses and discusses the current state of the art and trends in NTFP yield modelling in Europe and the integration of the models in multi-functional forest management planning at different spatial scales. Recent Findings Climate-sensitive empirical yield models already exist not only for a variety of NTFPs that are economically important to forest owners (e.g. cork and pine nuts) but also for wild-gathered berries and mushrooms, the harvesting of which cannot be controlled by the forest landowner in all European countries. Several studies on multi-functional forest management planning consider the economic profitability of the joint production of timber and NTFP. Harvesting NTFPs can create significant additional incomes for forest owners, compared with timber production only. However, maximizing the economic returns from the joint production of timber and NTFPs often calls for changes in forest management practices. Summary Continued efforts in modelling and predicting the yields of NTFPs have enabled forest managers to further expand the analyses of multi-functional forest planning and management in Europe. Climate-sensitive models also allow analyses on the potential effects of climate change on NTFP yields. New models and forest management practices are still needed for tree fruits, birch sap, a wider variety of wild edible mushrooms, specialty mushrooms cultivated on live trees as well as medicinal and edible forest herbs harvested for commercial value in Europe.

Are important phenomena of joint production still being neglected by economic theory? A review of recent literature

Joint production is a term with a long history in economics, encompassing a variety of ubiquitous production types that usually generate both main products as well as desirable and undesirable byproducts. However, studies in economic history show that important phenomena subsumed under this term were largely ignored by the theories of general economics and of business economics in the twentieth century. Our systematic, narrative literature review based on the Web of Science analyses the extent to which this and other terms corresponding to such phenomena have been taken up by researchers since then. Whereas the number of papers on undesirable outputs has soared, especially in the past decade, the economic literature regarding joint production and harmless byproducts is much smaller and hardly growing. This is in stark contrast to their relevance in practice, recorded in the non-economic literature. Harmful byproducts result from coupled production, as a rule. However, this important manifestation of joint production is usually not distinguished from other specific types. In German-language literature, coupled production is defined as a kind of (truly) joint production in which an intended product cannot be manufactured without an additional type of output under consideration. Our review reveals a lack of clarity, precision, and consistency in the use of established terms and concepts in English-language literature, that may lead to insufficient external validity of widely accepted models. Moreover, one gets the impression that academic disciplines concerned with business or general economics focus too much on problems that are currently of economic interest, while neglecting other issues that may be marginal today but are likely to be of critical importance in the near future.
