ArticleImpacts of the national forest rehabilitation plan and human-induced environmental changes on the carbon and nitrogen balances of the South Korean forests
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The carbon (C) balance is a key to the climate regulation role of forests, and the nitrogen (N) balance affects forest productivity, ground and surface water quality, and the emission of N2O. Humans have impacted the C and N balances, but quantification of the responses of forests to human activities is limited. This study aimed to quantify the impacts of the long-term national forest rehabilitation plan and the contribution of the increase in air temperature, CO2 concentration, and N deposition on the C and N balance of the South Korean forests during 1973–2020 by using a biogeochemical model. The C and N balance increased from 0.20 to 4.30 Mg C ha–1 year–1 and from 0.20 to 17.4 kg N ha-1 year-1, respectively. This led to the whole South Korean forests to newly store 825 Tg C and 3.04 Tg N after the national forest rehabilitation plan. The increase in air temperature, CO2 concentration, and N deposition contributed –11.5, 17.4, and 177 Tg C for the newly stored C stock, respectively, and –25.4, 8.90, and 1,807 Mg N for the newly stored N stock, respectively. This study would provide references on the benefits of forest rehabilitation for the C and N balance and for future forest rehabilitation efforts. Moreover, our findings improve the understanding of the impacts of human activities on the C and N balance.

DocumentEffects of forest experience activities on the change of happiness and nature-friendly attitudes on young children
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Nowadays, environmental damage has reached a serious state due to urbanization and industrialization, and with rapid economic growth based on capitalism, infants are gradually moving away from nature and living in artificial structures. They have been suffering from physical, mental stress and psychological disabilities since infancy due to various problems such as parents' high intellectual desire, changes in family members, and collapse of family. The purpose of this study was to investigate the psychological effects of the forest experience activities of 10 sessions (one time a week/2 hours) for young children. Forty infants (6 to 7 years old) participated in the forest experience activities (10 sessions, once a week/2 hours, a total of 10 weeks) held at the National Center for Forest Education, Daejeon (Korea). To examine the psychological effects before and after the participation, the happiness (parent relationships, peer relationships, cognition and achievement, immersion, spirituality, emotion, health, life satisfaction) and nature-friendly attitudes of the children (interest and affection for animals and plants, respect for life, preference for the natural environment, protection of nature) were measured. As a result of analyzing psychological indicators, all nine sub-factors of infant happiness improved, and overall infant happiness increased statistically significantly from 85.12 before participation to 99.91 after participation. In the case of nature-friendly attitudes, the nature protection item improved statistically significantly from 9.50 before participation to 11.42 after participation. It was confirmed that the 10 sessions forest experience activities were effective in enhancing the happiness of infants and improving the nature protection item of nature-friendly attitudes. Therefore, forest experience activities can be usefully utilized as a method of psychological health care for infants. Keywords: Human health and well-being ID: 3481876 -
ArticleVulnerability assessment of Ukrainian forests to climate change as the base of nature-based solutions for mitigation and adaptation
XV World Forestry Congress, 2-6 May 2022

No results found.A wide range of climatic conditions in Ukraine causes significant regional differences in the vulnerability of forests to climate change. The mitigation/adaptation strategy should be based on assessments of their vulnerability at the regional level. Phytoindication model by prof. Y.P. Didukh (1994) was used to assess forest vulnerability. The model gives a quantitative estimation of climate as one of major environmental factors affecting the distribution, condition and productivity of vegetation on the base of climate-related indicators – continentality, humidity and frost. For these indicators climate suitability scales were calculated. Modeling was carried out for main forest species: Pinus sylvestris L., Quercus robur L., Fagus sylvatica L., Picea abies (L.) H.Karst, Betula pendula Roth., Alnus glutinosa (L.) Gaertn. and Robinia pseudoacacia L. Climate projections based on the Euro CORDEX time series (up to 2100) and 2 scenarios of the Representative Concentration Pathways (RCP 4.5, RCP 8.5) were used. By means of Q-GIS the maps containing zones of suitability to climate for each of studied species were created for current climate conditions and future time series. The directions for strengthening the mitigation and adaptive capacity of forests are considered. The mainstream for nature-based solutions is adaptive sustainable forest management, which provides: 1)optimization of land use structure and increasing the forested area; 2) development and implementation of a national forestry program considering the priorities of climate change and low-carbon development; 3) using wood to substitute greenhouse gas intensive-materials and fossil fuels; 4) best forestry practices through the introduction of modern Climate Smart Forestry principles.
