DocumentOther documentSmell the disease - Developing rapid, high-throughput and non-destructive screening methods for early detection of alien invasive forest pathogens and pests featuring next-generation technologies
XV World Forestry Congress, 2-6 May 2022

No results found.Global forests are increasingly threatened by alien invasive pathogens and pests. The magnitude of this threat is expected to further increase in the future, due to the warmer climate and more extensive global transports and trade of plants. Pests and pathogens are often introduced to new areas by trade with ornamental plants as intermediate hosts, and there is a great need to modernize the tools for detection of alien species in imported plants and in monitoring of those that are already established in our forests. To achieve this goal, research in forest pathology is focused on combining recent technological advances in robotics, next generation sequencing, and mass spectroscopic methods with knowledge about the specific metabolic responses in the pests and pathogens and the trees that they infest. Gas Chromatography (GC) Analysis of Volatile Organic Compounds (VOCs) adsorbed on Solid Phase Micro-Extraction (SPME) fibers is one promising method with potential for high-throughput detection of larger plant shipments. By the establishment of a library of chemical fingerprints characterizing specific pests and pathogens, one could non-destructively scan a large number of plants in ports or nurseries to eliminate presence of disease. The species-specific combination of VOCs can be utilized to prevent introduction of harmful pests and pathogens to new markets. One pathogen considered as a quarantine species and a serious threat on-the-horizon for coniferous forests is Pine Pitch Canker (PPC), a fungal pathogen affecting a variety of pine species with devastating economical and biological consequences, especially if it were to be established in a country like Sweden where about 38% of the standing forest volume consist of pine. Pathogens like this one are already introduced in several European countries, and need to be monitored and identified early to prevent further forest damage – a challenge that Forest pathologists have accepted.

ArticleJournal articleHistory lessons from the late Joseon Dynasty period of Korea: Human technology (Ondol), its impacts on forests and people, and the role of the government
XV World Forestry Congress, 2-6 May 2022

No results found.Historical analogies can help us contextualize new technical developments with social, cultural, and political forces at work. The late Joseon Dynasty period of Korea (1639–1910), a closed economy with detailed written records, provides a rare opportunity to examine a social-ecological system (SES) responding to drivers of change over a long period of time. Based on historical records and reconstructed data, we aim to: (1) characterize how the expansion of human technology, Ondol (traditional underfloor heating system), affected different subsystems and their interactions within the SES over time; (2) examine the role of the government in promoting the technology and regulating its impacts; (3) summarize the pertinent lessons learned from old Korea for governing a modern-day bioeconomy. Ondol allows various forest biomass to be utilized as household fuel, including fuelwood, forest litter, and grass scraped from forest floor. Continuous biomass harvesting over 250 years to feed Ondol contributed to forest degradation and forest ecosystem condition trapped in the early successional stage in the Korean Peninsula. The ecological changes were exacerbated by the Pine Policy with a singular focus on reserving Korean red pine (Pinus densiflora) for government uses. The policy failed to recognize basic needs of the public while countenancing an expansion of Ondol and a cultural preference for heated floors that propagated an increased use of biomass fuel. This case illustrates the importance of recognizing potential technology traps where a human innovation opened opportunities for more resource use. The lessons learned from old Korea show that bioeconomy transitions would require multifaceted governance responses, while being cautious about being too closely tied to the dominant national agenda.

DocumentOther documentSpatial distributions pattern and associations of dead woods in natural spruce-fir secondary forests
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Natural secondary forest is the main part of forest resources in China. Studying dead woods (DW) could better reveal the community succession rule and promote the healthy development of them. We investigated basic characteristics and coordinates of each tree (DBH≥1 cm) within a plot (100 m×100 m) using the adjacent grid method and studied the spatial distributions pattern and associations of DW (in the last five years) in a typical natural spruce-fir secondary forest in Jingouling Forest Farm, Wangqing Forestry Bureau, Jilin Province, China. The results showed that the diameter class distribution of DW showed the pattern of left-single-peak curve, while the logs showed the pattern of multi-peak curve. DW number was related to the mixing degree of one species, but not to the total number of it. The distribution of DW was concentrated at 0~8m scale. As the scale increases, it changed to random or uniform. The aggregation distribution of DW of medium (10 cm≤DBH<20 cm) and small (1 cm≤DBH<10 cm) DBH at small scale below 8 m was the main reason for the aggregation distribution of DW. The DW of large (DBH≧20 cm) DBH and Saplings (1 cm≤DBH<5 cm) showed a significant positive association at 2~25 m scale. There was no significant spatial association between DW and Small trees(5 cm≤DBH<15 cm). At 0~3m scale, there was a positive association between Medium trees (15 cm≤DBH<25 cm) and DW of small and medium DBH. At the 9 m, 11~14 m scale and the 15 m, 42~45 m scale, the DW of small and medium DBH were significantly negatively associated with Large trees (DBH≥25 cm). In conclusion, the biological traits, diameter class distribution and spatial distribution affected the abundance and diameter class distribution of DW of one species. The spatial distributions of DW and the associations between DW and standing trees varied across diameter classes and scales. Rational utilization of spatial information could optimize stand structure and promote positive community succession.

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. -
