No results found.After decades of research and development, Silvanus Forestry Ltd. and HungaroPlant Ltd. have successfully propagated the Robinia pseudoacacia ’Turbo Obelisk’ variety group and developed the necessary cultivation technologies, specifically for intensive industrial wood production plantations. In comparison to the Hungarian and traditional black locust varieties and cultivation technology, industrial wood production plantations established with our variety group and using our cultivation technologies are able to produce twice as much timber yield and industrial timber yield, considering 15-year rotation periods. These parameters are comparable with the performance of the widespread Eucalyptus and Pinus plantations in the subtropics. Our varieties and cultivation technologies however, are also usable in subtropical, temperate, as well as tropical climates. The outstanding yields achieved by the ‘Turbo Obelisk’ varieties and the extremely high industrial hardwood output can provide a significant contribution to the conservation and maintenance of natural ecosystems, whilst the CO2 sequestration per unit area per time is also several times that of natural forests. Another vital advantage is the long term carbon sequestration due to the high percentage of industrial wood yield.Increasing the exceptional tolerance of black locust against drought, pollution and low quality soils, our varieties are exceptionally suitable for the utilization of marginal agricultural areas, the agricultural utilization of which would otherwise create an economical loss. This can also significantly increase the advancement of less developed regions. In addition to plantation cultivation, it also provides a cost effective solution for the establishment of protective forest belts, road-side plantings, quicksand fixation and soil renovation. Delicious honey production is also a possible revenue stream.Test plantations have been established in China, India, Pakistan and several European countries.

ArticleJournal articleForest plantations for wood growing in the European north of Russia
XV World Forestry Congress, 2-6 May 2022

No results found.The Russian Federation has accumulated quite a lot of experience in plantation forestry. An urgent issue of returning unused agricultural land to economic circulation can be solved by creating plantation crops on these lands, which contributes to the achievement of the Sustainable Development Goals on rational forest management, restoration, afforestation and reforestation (SDGs 2, 12, 15 and GFGs 1 and 2). Research on the creation of targeted forest plantations in the European North of Russia was carried out within the framework of a state assignment. Well-grounded conclusions on the choice of species for targeted plantation cultivation were made. Preference should be given to aboriginal species (Scots pine, European spruce). However, one of the promising fast-growing species suitable for the pulp and paper industry in temperate countries is Lodgepole pine (Pinus contorta Loud. var. latifolia S. Wats.), naturally growing in North America. Based on long-term research, the most suitable origins of Lodgepole pine were selected – located in regions of the most northern Canadian origin (Yukon), where it grows at the northern limit of the distribution of forest species. The advantage of Lodgepole pine over local coniferous species was revealed while growing on industrial forest plantations, where, by the age of 40-50 years, it forms 250-300 m3/ha of low-resinous wood, suitable for both sulfate and sulfite pulping and is 70% more productive than local spruce and pine. In the research process, the basic requirements for plantation crops in the European North of Russia were developed, under which plantations justify their purpose. One of the main innovative areas of research is the development of technology for creating forest plantations on lands that have come out of agricultural use.

DocumentOther documentIsolation of DNA from preserved woods for identification of wood species through genetic analysis regardless of the age of wood production

No results found.Species identification of wood provides important information for archaeology, restoration of cultural assets, preventing illegal logging, and more. Wood species are usually identified based on their anatomical features with the use of a microscope. However, this method may not be able to distinguish between anatomically similar species or subspecies. To overcome this problem, wood species need to be identified at the molecular level using DNA sequencing. However, unlike living plant cells, wood is difficult to pulverize using a mortar, and DNA extraction from dried wood is challenging. To solve these problems, we propose a pretreatment method in which wood is pulverized using 60-grit sandpaper and hydrated with water for 2 days. Using this method, we were able to stably amplify the rpoB gene from the extracted DNA of Pinus rigida. In addition, sequence analysis of the rpoB gene revealed six single nucleotide polymorphisms (SNPs), which classified the rpoB sequences in the genus Pinus into five groups. Our data indicate that although these SNPs were not suitable for species identification, they can potentially be used to determine the origin of different wood subspecies or individual samples of wood.

BookletHigh-profileFAO Strategy on Climate Change 2022–2031 2022The FAO Strategy on Climate Change 2022–2031 was endorsed by FAO Council in June 2022. This new strategy replaces the previous strategy from 2017 to better FAO's climate action with the Strategic Framework 2022-2031, and other FAO strategies that have been developed since then. The Strategy was elaborated following an inclusive process of consultation with FAO Members, FAO staff from headquarters and decentralized offices, as well as external partners. It articulates FAO's vision for agrifood systems by 2050, around three main pillars of action: at global and regional level, at country level, and at local level. The Strategy also encourages key guiding principles for action, such as science and innovation, inclusiveness, partnerships, and access to finance.

Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms. -
Book (series)FlagshipThe State of Food Security and Nutrition in the World 2023
Urbanization, agrifood systems transformation and healthy diets across the rural–urban continuum
2023This report provides an update on global progress towards the targets of ending hunger (SDG Target 2.1) and all forms of malnutrition (SDG Target 2.2) and estimates on the number of people who are unable to afford a healthy diet. Since its 2017 edition, this report has repeatedly highlighted that the intensification and interaction of conflict, climate extremes and economic slowdowns and downturns, combined with highly unaffordable nutritious foods and growing inequality, are pushing us off track to meet the SDG 2 targets. However, other important megatrends must also be factored into the analysis to fully understand the challenges and opportunities for meeting the SDG 2 targets. One such megatrend, and the focus of this year’s report, is urbanization. New evidence shows that food purchases in some countries are no longer high only among urban households but also among rural households. Consumption of highly processed foods is also increasing in peri-urban and rural areas of some countries. These changes are affecting people’s food security and nutrition in ways that differ depending on where they live across the rural–urban continuum. This timely and relevant theme is aligned with the United Nations General Assembly-endorsed New Urban Agenda, and the report provides recommendations on the policies, investments and actions needed to address the challenges of agrifood systems transformation under urbanization and to enable opportunities for ensuring access to affordable healthy diets for everyone.
