DocumentThe current situation and perception analysis of forest carbon offset scheme in Korea
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.As the international community pays attention to the absorption of carbon using forests, Korea has been operating the Forest Carbon Offset Scheme since 2013. However, monitoring performance to be performed for certification is sluggish, and it was found that there is a limit to sustainable operation. This study aims to analyze current situation and perception of Forest Carbon Offset Scheme in Korea to suggest problems and direction of improvement.
Through literature surveys and interviews, in-depth interview questions were selected, and people in charge of transaction-type projects were interviewed in-depth. The Survey was conducted on people in charge, and the characteristics of perception were analyzed through descriptive statistical and frequency analysis.
The main expected effect was profit generation, and the overall perception of the expected effect decreased. Hindrances were in the order of "Concern about transaction possibilities", "Complexity of certification procedure", "Lack of competent professionals", "Lack of support costs for project planning", "Administrative delay" and "Lack of project operators’ expertise". Also, there were some issues in need of improvement in three aspects. First, there were issues with “Complexity of certification procedure”, “Lack of competent professionals”, “Lack of support costs for project planning”, and “Administrative delay” in system and operation. Second, there were issues with “Concern about transaction possibilities” in profitability. Third, there were issues with “Lack of project operators’ expertise”, “Gap between business purpose and expectation” in participants’ characteristics and perception.
This study proposed "Providing guidelines and information on the project through periodic identification of the people in charge", "Emphasizing awareness as a project for social contribution", and "Encouragement of revenue generation from non-carbon revenue sources" for improvement of scheme.

ArticleComparative study on the efficacy of biobased wood preservative over conventional wood preservatives against fungi and termites
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The current focus of wood preservation research is on developing wood preservatives from natural and environmentally compatible compounds for industrial application. Liquefaction of wood is one of the promising approaches to utilize woody waste where the wood meal is converted into a chemically active liquid with the help of a liquefying agent like polyhydric alcohols, phenol, cresol, and plant-based solvent as CNSL and Cardanol. Conventional wood preservatives like CCA, ASCU, Creosote, Chlorpyriphos based temic and termisel as synthetic chemicals were in use for a long time, has also been used in prescribed proportion. The efficacy and economic suitability of liquefied wood as a wood preservative along with conventional wood preservative against termite and fungi have been studied. Wood samples were impregnated with both conventional and liquefied wood diluted with methanol and were subjected and evaluated as per Bureau of Indian Standards (BIS) in terms of its antifungal (IS4873, Part I:2008) and termiticidal activities (IS4833:1993) accelerated termite graveyard test and fungal resistance test. The level of impregnation of liquefied wood in wood was estimated by determining the weight percent gain. In the graveyard test, samples were periodically observed for 24 months. The results indicated that Samples treated with phenol-assisted liquefied wood, CNSL based wood polyols, Cardanol based polyols exhibited better results as compare to conventional synthetic wood preservatives both in visual observation and percentage weight loss as compare to initial condition and untreated control samples. The percentage weight loss of liquefied wood polyols (phenol, CNSL, and cardanol individually) treated wood sample was ranging from only 5-20% of its initial weight; wood treated with preservatives (CCA, ASCU, Creosote and chlorpyriphos) shows % weight loss varied from 40- 60% and did not exhibit better resistance against termite and fungi as compared to the untreated samples. The treated samples were also exposed to fungus for 16 weeks. The fungicidal traits of liquefied wood polyols (phenolated, CNSL, and cardanol individually) treated wood showed higher antifungal efficacy against both white rot and brown rot of wood, conventionally wood treated preservatives (CCA, ASCU, Creosote and chlorpyriphos) shows low efficacy against termite and fungus. Since wood residue is a byproduct of primary and secondary wood processing industry whereas CNSL and Cardanol are by-products of Cashewnut processing unit, so its utilization as wood preservatives will be a value-added product to the wood-based Industry...

DocumentIsolation of DNA from preserved woods for identification of wood species through genetic analysis regardless of the age of wood production
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
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.
