Both in Germany and in China, there is strong expertise regarding the different aspects of forest management, as well as forest products management. Nevertheless, forestry in both countries is facing challenges, some of which are regional, but many of which are shared. Therefore, experts from both countries (Technical University of Munich Germany; Northwest A&F University Yangling, China; Forestry Academy of Shaanxi, China; Thünen Institut, Germany; FEDRC GIZ Forest Policy Facility (Forestry Economics Development and Research Center of the Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH), Germany; and Center for Natural Forest Protection in Shaanxi, China) met to share their knowledge and deduce recommendations for future multifunctional forest management for the temperate zone. The workshop, held at the Northwest A&F University in September 2018, included presentations and intensive discussions, as well as a field tour. The results of the workshop that are summarized in this white paper are meant to provide an overview of the multi-faceted nature of the topic for interested scientists and forest practitioners, describe tools that can be used to analyze various aspects of multifunctionality and, in an exemplary fashion, highlight gathered experience from long- and short-term experiments. Included are social demands, economic goals, and scientific baselines. The topics reach from economic evaluations of forest ecosystem services over forest management practices, including afforestation, restoration, and preparations to face climate change, to wood/forest products utilization and participation of local people for poverty reduction. Overall, an optimistic picture emerges, showing that by using adapted forest management practices, which try to embrace the concept of multifunctionality, various use schemes and demands can be integrated at single sites, allowing us to achieve both environmental protection and productive forests, including societal demands, as well as aspects of tradition and national identity.

The EU Biodiversity Strategy (EUBDS) for 2030 aims at regaining biodiversity by strengthening the protection of nature in the European Union. This study models and analyses possible impacts of the EUBDS on the production and trade of forest-based products in the EU and non-EU countries in two alternative scenarios. Implementing EUBDS measures would allow a maximum EU roundwood production of roughly 281 M m3 in 2030 in the intensive and 490 M m3 in the moderate scenario. Since in the reference scenario, the EU roundwood production amounts to 539 M m3 in 2030, this represent a reduction of −48% and −9% in 2030, respectively. Until 2050, the production further decreases and accounts for 42% and 90% of the reference production. Globally, the EU roundwood production deficit is compensated partly (roughly between 50%–60%) by increasing production of roundwood in non-EU countries (e.g., USA, Russia, Canada, China and Brazil) whereas the remaining share of the EU production deficit is no longer produced and consumed worldwide. In the EU, reduced roundwood availability leads to a lower production of wood-based products, although, apparent consumption of wood-based products remains similar. This is mainly caused by significantly lower export volumes of wood-based products and, for some product groups, by significantly increased imports as well. This is partly due to unchanged assumptions regarding income and thus, demand patterns. However, on a global level, decreased production and consumption of wood-based products could lead to a growing use of non-bio-based resources to substitute wood-products. Our study also shows that the magnitude of effects strongly depends on how much the use of forest resources is actually restricted.

Background and objectives: Smallholder households with a plot size of 1–5 ha manage nearly half of Vietnam’s acacia plantations. They mostly harvest acacia timber after short rotation periods (5–6 years) producing woodchips with relatively low financial returns compared to potential profits from sawlog production through long rotation periods. The domestic wood production cannot yet meet the needs of the booming furniture industry for raw materials. This paper investigates factors that influence the adoption of long-rotation periods for sawlog production by small-scale plantation owners. Materials and methods: The impact of farmer and farm characteristics and the characteristics of the external environment on the probability to adopt long rotation periods is analyzed. The data were collected through focus group discussions (FGD) and a household survey to capture the wider socio-economic situation of small-scale plantation owners in central Vietnam. Findings: Results from FGDs and probit regressions show that factors that potentially constrain small-scale plantation owners from the production of sawlogs can be grouped into four themes: (1) small and fragmented land holdings, (2) high risks related to natural disasters and other biotic and abiotic hazards, (3) high production and monitoring costs, and (4) lack of knowledge and experience in plantation management. Conclusions: Potential policy approaches to promote the adoption of long rotation periods should include a package of measures that simultaneously address the constraints of smallholders and the various risks that they face.

Tropical forests, and more concretely, the Amazon Basin and the Chocó-Darién, are highly affected by deforestation activities. Households are the main land-use decision-makers and are key agents for forest conservation and deforestation. Understanding the determinants of deforestation at the household level is critical for conservation policies and sustainable development. We explore the drivers of household deforestation decisions, focusing on the quality of the forest resources (timber volume potential) and the institutional environment (conservation strategies, titling, and governmental grants). Both aspects are hypothesized to influence deforestation, but there is little empirical evidence. We address the following questions: (i) Does timber availability attract more deforestation? (ii) Do conservation strategies (incentive-based programs in the Central Amazon and protected areas in the Chocó-Darién) influence deforestation decisions in household located outside the areas under conservation? (iii) Does the absence of titling increase the odds of a household to deforest? (iv) Can governmental grants for poverty alleviation help in the fight against deforestation? We estimated a logit model, where the dependent variable reflects whether or not a household cleared forest within the farm. As predictors, we included the above variables and controlled by household-specific characteristics. This study was conducted in the Central Amazon and the Chocó-Darién of Ecuador, two major deforestation fronts in the country. We found that timber volume potential is associated with a higher odds of deforesting in the Central Amazon, but with a lower odds in the Chocó-Darién. Although conservation strategies can influence household decisions, the effects are context-dependent. Households near the incentive-based program (Central Amazon) have a lower odds of deforesting, whereas households near a protected area (Chocó-Darién) showed the opposite effect. Titling is also important for deforestation reduction; more attention is needed in the Chocó-Darién where numerous households are living in untitled lands. Finally, governmental grants for poverty alleviation showed the potential to generate positive environmental outcomes.

The EU Biodiversity Strategy 2030 (EUBDS) aims to preserve and restore biodiversity by protecting large areas in the EU. An extensive part of these protected areas will presumably be covered by forests. This study analyses the economic effects of EUBDS implementation on German forestry in two scenarios, based on different possible interpretations of the EUBDS’ key commitments, using a forest economic simulation model. A special focus is placed on the opportunity costs of coarse wood debris (CWD). Over a simulated 200-year period, a decrease in timber harvest of 13% and 44% is estimated under the respective scenario assumptions. This leads to a reduction in the silvicultural contribution margin (SCM) of on average 0.25 B EUR a−1 (14%) and 0.79 B EUR a−1 (45%). In terms of the total SCM, protected forests contribute 35% and 15% in the two scenarios. The accumulation and preservation of CWD incurs a substantial loss of utility, as 15% and 19% of annual logging is required for conservation purposes. However, the EUBDS may also provide economically tangible benefits. A rational decision would be to implement a scenario if the “net benefit” from the protected status exceeds the losses from set-aside and conservation requirements.
