Forests sourcebook : practical guidance for sustaining forests in development cooperation
The 'Forests Sourcebook' provides practical operations-oriented guidance for forest sector engagement toward the goals of poverty reduction, conservation and economic development. Intended to guide World Bank lending activities and projects, the 'Forests Sourcebook' offers information useful to a broad audience of practitioners, government agencies, and non-governmental organizations. The 'Sourcebook was developed in partnership with members of the Collaborative Partnership on Forests, including the Food and Agriculture Organization. The 'Sourcebook' provides background on key issues, lessons learned, and recommendations for practitioners on a number of topics including private sector engagement, forest governance, sustainable plantation and commercial harvesting, and forest information management systems. Giving insight into the complex interplay between different realms of development work that effect or are affected by forests, the 'Forests Sourcebook' is a valuable tool for any stakeholder involved in development or business projects that could have impact on forests.

Comparing Sustainable Forest Management Certifications Standards
To solve problems caused by conventional forest management, forest certification has emerged as a driver of sustainable forest management. Several sustainable forest management certification systems exist, including the Forest Stewardship Council and those endorsed by the Programme for the Endorsement of Forest Certification, such as the Canadian Standards Association – Sustainable Forestry Management Standard CAN/CSA - Z809 and Sustainable Forestry Initiative. For consumers to use certified products to meet their own sustainability goals, they must have an understanding of the effectiveness of different certification systems. To understand the relative performance of three systems, we determined: (1) the criteria used to compare the Forest Stewardship Council, Canadian Standards Association – Sustainable Forestry Management, and Sustainable Forestry Initiative, (2) if consensus exists regarding their ability to achieve sustainability goals, and (3) what research gaps must be filled to improve our understanding of how forest certification systems affect sustainable forest management. We conducted a qualitative meta-analysis of 26 grey literature references (books, industry and nongovernmental organization publications) and 9 primary literature references (articles in peer-reviewed academic journals) that compared at least two of the aforementioned certification systems. The Forest Stewardship Council was the highest performer for ecological health and social sustainable forest management criteria. The Canadian Standards Association – Sustainable Forestry Management and Sustainable Forestry Initiative performed best under sustainable forest management criteria of forest productivity and economic longevity of a firm. Sixty-two percent of analyses were comparisons of the wording of certification system principles or criteria; 34% were surveys of foresters or consumers. An important caveat to these results is that only one comparison was based on empirically collected field data. We recommend that future studies collect ecological and socioeconomic data from forests so purchasers can select certified forest products based on empirical evidence.

Provenance and family variations in early growth of Manchurian walnut
This study, conducted in China in November 2020, was aimed at exploring the variations in growth traits among different provenances and families as well as to select elite materials of Juglans mandshurica. Thus, seeds of 44 families from six J. mandshurica provenances in Heilongjiang and Jilin provinces were sown in the nursery and then transplanted out in the field. At the age of 5 years, seven growth traits were assessed, and a comprehensive analysis was conducted as well as selection of provenance and families. Analysis of variance revealed statistically significant (P 0.8) between tree height and ground diameter (r = 0.86), tree height and mean crown width (r = 0.82), and ground diameter and mean crown width (r = 0.83). This suggests that these relationships can be employed for more precise predictions of the growth and morphological characteristics of trees, as well as the selection of superior materials. There was a strong correlation between temperature factors and growth traits. Based on the comprehensive scores in this study, Sanchazi was selected as elite provenance. Using the top-percentile selection criteria, SC1, SC8, DJC15, and DQ18 were selected as elite families. These selected families exhibit genetic gains of over 10% in tree height, ground diameter and mean crown width, signifying their significant potential in forestry for enhancing timber production and reducing production cycles, thereby contributing to sustainable forest management. In this study, the growth traits of J. mandshurica were found to exhibit stable variation, and there were correlations between these traits. The selected elite provenance and families of J. mandshurica showed faster growth, which is advantageous for the subsequent breeding and promotion of improved J. mandshurica varieties.

Abrupt increase in harvested forest area over Europe after 2015
Forests provide a series of ecosystem services that are crucial to our society. In the European Union (EU), forests account for approximately 38% of the total land surface

. These forests are important carbon sinks, and their conservation efforts are vital for the EU’s vision of achieving climate neutrality by 2050

. However, the increasing demand for forest services and products, driven by the bioeconomy, poses challenges for sustainable forest management. Here we use fine-scale satellite data to observe an increase in the harvested forest area (49 per cent) and an increase in biomass loss (69 per cent) over Europe for the period of 2016–2018 relative to 2011–2015, with large losses occurring on the Iberian Peninsula and in the Nordic and Baltic countries. Satellite imagery further reveals that the average patch size of harvested area increased by 34 per cent across Europe, with potential effects on biodiversity, soil erosion and water regulation. The increase in the rate of forest harvest is the result of the recent expansion of wood markets, as suggested by econometric indicators on forestry, wood-based bioenergy and international trade. If such a high rate of forest harvest continues, the post-2020 EU vision of forest-based climate mitigation may be hampered, and the additional carbon losses from forests would require extra emission reductions in other sectors in order to reach climate neutrality by 2050

Fine-scale satellite data are used to quantify forest harvest rates in 26 European countries, finding an increase in harvested forest area of 49% and an increase in biomass loss of 69% between 2011–2015 and 2016–2018.
