In the current scenario, every country is concerned about the severe exploitation of forests and the ensuing lack of markets for timber. Production and consumption of wood and wood products by the G20 countries account for 85% of global GDP and two-thirds of the world's population. Data for the study includes eight major categories of wood products in the G20 countries from 2004 to 2021: industrial raw wood, sawlogs and veneer logs, sawn wood, wood fuel, wood-based panels, paper and paperboard, pulp for paper, wood pellets, and other agglomerates. Autoregressive integrated moving average (ARIMA) models were used to predict the production, export, and import behaviour of wood and wood products from 2022 to 2030. According to the findings, the G20 countries would consume 1 644.6 million m3 of industrial raw wood in 2030, followed by 984.8 million m3 of sawlogs and veneer logs, 454.7 million m3 of sawn wood, 882.5 million m3 of wood fuel, 406.2 million t of paper and paperboard, 199.4 million t of pulp for paper, and 51.7 million t of wood pellets and other agglomerates. This study provides decision-makers with an analysis of the production and consumption of wood product markets in the G20 countries, which can be used for policy decisions.

Crantz]. The germination tests (4 × 100 seeds) were conducted in two runs in 2020 and 2021; they were performed for three seed lots and three cold stratification periods (two, three and four months) before the testing of germination in each run. The values of germination energy and germination capacity were assessed, and the germination rate was computed. The results showed that the two-month cold stratification period has not been sufficient to overcome the dormancy of tested seeds. Regardless of the year in which the tests were conducted, seeds stratified for two months showed almost zero germination. For seeds treated with three- and four-month cold stratification, the germination percentage varied from ca. 5% to 32% and from ca. 13% to 46%, respectively. Our results basically correspond with findings reported in the reviewed literature. In 2020, the seeds subjected to four-month stratification performed significantly better than the seeds subjected to three-month stratification. However, in 2021, the seeds stratified for three months reached slightly better results. Four-month stratification also led to an increased percentage of prematurely germinated seeds during stratification. To conclude, the two-month period of cold stratification proved to be insufficient and at least three months of cold stratification are needed to obtain the adequate germination of seeds in subsequent laboratory tests.

The Russian Federation, as one of the world's largest pellet producers, has an opportunity to utilise pellets domestically. This study addresses the lack of publicly available life cycle assessment (LCA) studies on pellet production and utilisation in Russia, specifically examining the environmental impact of residential heat production from locally produced wood pellets. Utilising primary data from the Northwest region, the study follows ISO 14040 and 14044 standards and employs the ReCiPe 2016 (H) Midpoint v. 1.1 method to assess environmental impacts. The results indicate that the production of pellets is the dominant contributor to the global warming impact category, marine eutrophication, and fossil resource scarcity, while transportation has the least impact across all categories. Sensitivity analyses confirm the robustness of these findings, revealing that using natural gas for pellet drying increases emissions for global warming and fossil resource scarcity, and increasing transportation distance significantly raises emissions across all categories. The findings provide valuable insights for policymakers and stakeholders aiming to enhance the sustainability of similar bioenergy systems.

This study surveyed visitors at 'Forestry Days 2024' in Slovakia through face-to-face questionnaires, capturing their views on FES and necessary management changes. Results show that regulating services and biodiversity are prioritised over cultural and provisioning FES. Respondents indicated a clear need for changes in forest management to reflect their FES preferences. Notably, perceptions of specific FES varied by gender, age, forestry background, and forest ownership but not by residence type. Public PES were considered the most acceptable policy for enhancing FES management, providing valuable insight for aligning public preferences with sustainable practices in Slovakia.
