ArticleA species-specific approach for tracing Brazilian timber origins and associated illegality risks across the supply-chain
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The rise in global demand for agricultural and forest commodities have created unparalleled pressure on forests, leading to loss of carbon, biodiversity, ecosystems services, and livelihoods. While we know more about how commodity production and trade is linked to deforestation, such connection still largely unexplored for forest degradation despite the threat rivaling or exceeding that of deforestation. Timber extraction is the largest direct anthropic driver of forest degradation and its illegal share a pervasive source across domestic and international markets. Here we seek to lay the foundations for connecting localities of production to consumption, presenting a species- specific approach to quantifying sources of illegality risk across the supply chain. By adapting material flow analyses and environmentally extended input-output models to timber originating from Brazilian native forests, we demonstrate how distinct risks can be mapped and quantified. We focus on the Amazon state of Pará; a leading producer of timber, of high-value ipê, and contested forest frontier. Data on logging permits and state-level Document of Forest Origin are used to estimate sources of illegality risk associated with overstated ipê yields, unclear forest of origin and discrepancies resulting from missing physical flows. We find that less than one fourth of all ipê volume entering supply-chains in 2017-2019 is risk-free. The area explored under logging permits and volumes entering the supply chain suggest an average yield of 1.6 m3ha-1, which exceeds the 90% percentile of reported ipê tree densities for region. Nearly a third of supply-chain flows cannot be accounted for by Pará’s state-level system. Despite important limitations to this study, it puts forward an approach that can be refined and leveraged to monitor illegally logged timber entry- points and can contribute to increased transparency in Brazilian timber supply chains.

DocumentCommunicative competence in the English language, a tool at the service of Forest science. Materials for its development
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Given the vertiginous growth of information and knowledge, it is necessary to guarantee a quality education for new forestry engineers that builds the will and capacity to take advantage of the use of forest resources in order to improve life, health and wellness. Within the framework of this process, the present work aims to expose how the development of communicative competence in the English language is favored for professional purposes based on the understanding and construction of texts in connection with those arts that recreate aspects of the context of science Forest; from contents organized in specific themes linked, mainly, to painting and landscape architecture that support communication. Learning materials are designed that constitute a working tool for teachers and students in order to face the communicative challenges presented that educate for communication between members of the forest community. Training in English at the service of Forest science linked to the arts through the aforementioned materials provides useful lessons: the dialogue established in planned learning situations enhances academic performance; as well as, the formation of international competencies in function of being and acting as professionals for the contemporary and future world to promote alliances and cooperation on a global scale in favor of the conservation of forests.

DocumentSpecies recovery strategy using genetically appropriate material of Abies koreana, an endangered fir species that is endemic to Korea
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.In this study, we present a strategy of restoring genetic diversity for conservation of Abies koreana, an endemic species vulnerable to climate change, and especially a species recovery strategy for small populations with high threat of extinction. Species recovery strategy is a restoration method that maintains population vitality and resilience by utilizing genetically appropriate materials to adapt well to future environmental conditions. Korean fir (Abies koreana E.H.Wilson), which is a Korean endemic species that has been designated as an endangered species by the International Union for Conservation of Nature. There are three large and six small populations with a relatively large and small number of individuals, respectively. According to the genetic analysis of the large-scale population of A. koreana, the genetic diversity of each group is relatively high and remains stable to date. According to the spatial genetic structure analysis for selecting the restoration materials to avoid inbreeding depression, it is appropriate to select Mt. Jirisan population at intervals of about 30 meters between individuals and Mt. Hallasan group of about 15 meters. A total of six small populations of A. koreana in Korea, have a distribution area of less than 1ha. Small population with a restrict distribution has high risk of extinction due to low number of individuals, low genetic diversity and low seedlings in the population, so it is necessary to restocking method. Selecting the restoration materials for the small population needs to consider the genetic diversity and uniqueness of the natural population while enhancing their adaptability and resilience against environmental change. In order to restore genetic diversity of small populations to maintain the resilience, an approach is needed to evaluate the genetic similarity between the populations in Korea and to introduce appropriate restoration materials considering genetic diversity.
