The research on Customary Forest (CF) has become more widely discussed after the implementation of Constitutional Court Determination (CCD) 2012. The related research is discussed in not only the forest science field, but also in anthropology, economic development, and geography. This poster aims to review the literature on the CF development and discusses the main issues studied, including lesson learned from institutional and social perspectives. The results shows that the studies mostly focused on the institutional dynamic on CF development. It is including the actor’s connection, supporters, and inhibitors on its development process. Those studies mainly focus on western region in Indonesia. The main benefit of CF recognition is the authority to regulate its own traditional territory. While the barriers come from the absence of national regulation, dependence on the presence of indigenous NGOs, and the weakness of the issue of customary forests urgency at the regional and local level.
The study tries to identify the major challenges of the agroforestry products supply chain in Bangladesh and offer a good solution within the experiences of the Japanese cooperative model. The results clearly showed that the involvement of many intermediaries in the agroforestry products supply chain was one of the main obstacles in Bangladesh. The intermediaries have maximized their profit by buying the farmers' products at a lower price and selling them back at a higher price and resulting high marketing margin. On the contrary, the Japanese case study had articulated that the farmer-driven cooperative approach with good marketing strategies and service functions can successfully eliminate the intermediaries’ involvement in farmer products and make the cooperative a strong economic organization. So, the farmer-driven Japanese cooperative approach would be a good solution to tackle the middleman problem and make agroforestry a sustainable production system in Bangladesh.
The 2019 IPCC report approved that global warming of 1.5℃ will be exceeded between 2021 and 2040 if the current level of greenhouse gas emissions is maintained until the middle of this century. As global warming accelerates, climate change rapidly and frequently occurs. It also contributes to the plant extinction and loss of biodiversity. Recently, Diabelia spathulata is a critically endangered (CR) species designated by The National Arboretum of the Korea Forest Service and the habitat of D. spathulata is Cheonseongsan Mountain in Yangsan-si, Gyeongsangnam-do, where is the only native habitat site in Korea. In addition, the number of populations is very small, so it is necessary to conserve their habitats and germplasm. Various ecological researches including environmental conditions, distribution range, and vegetation structure of D. spathulata have been conducted. However, there are few reports of propagation by cuttings and micropropation of D. spathulata. Development and establishment of propagation and in vitro regeneration systems is essential for clonally and mass propagation. Thus, the purpose of this study was to find and optimize the best cutting propagation and regeneration conditions of an endangered D. spathulata.
This study was conducted to prevent land creeping by examining various features such as geology, topography, and physical characteristics, using the case of a land-crawled region. The first land creeping occurred in Seomyeon Suncheon-si in 2000, and the second occurred in 2020; the damaged surface area of the second event was approximately 21.7 times that of the first, and it was discovered Sunchoen-si Landcreep occur because of forest road cut affected. and the clay soil between the bedrock was mild to severe, and it was determined to be severe in locations where groundwater was leaching. The objective study area was a typical land creeping-type landslide caused by weathered rocks, and this area belonged to a type of convex terrain ground (凸) form. The land creeping occurred in the convex area (凸). As a result of analyzing the landslide hazard grade(Using Gis Arc map Ver. 10.8), the creeping land area is found to be different from ordinary landslides because it includes most areas of landslide hazard grade 3–5 and out of the grade. Results show that the land creeping has proceeded in the directions of S15°E, S20°E, S25°E, and S30°E.
This study was conducted to establish basic data for calculating the risk grade of land push in the future by comparing and analyzing landslide disasters and land push that generally occur using the landslide risk determination standard table. Among the factors influencing 57 landcreep areas nationwide, slope length, slope location, clinical, slope type, soil depth, slope, etc. were selected and classified according to the landslide risk determination standard table, and then correlation between slope type and rock was significant at 5%. Excluding this, there were statistically insignificant results among factors, and judging by these results, it is considered that the landslide risk determination standard table is not suitable for applying to the ground push. Of the 57 landcreep sites in Korea, 35 areas (about 61.4%) are unlikely to have landslides or are not likely to have landslides, making it difficult to accurately determine if landcreep is judged as a landslide risk determination standard. In 57 land forests, the largest number of areas were classified as areas other than landslide risk grades that were not included in landslide risk grades 1 to 5, indicating that many areas were not included in the landslide risk grade.
Kudzu is an invasive vine and has raised a serious concern by stealing sunlight from its neighboring plants in forest plantation. Salt treatment was conducted to evaluate its efficacy for kudzu removal. A total of 157 kudzu crown roots were cut in half in Danyang, Sangju, and Yanggu in July 2020. Different amounts of sodium chloride (0, 20, 40, 60, 80, and 100 g) were added to the cut surface of crown roots according to crown diameters. Three months after salt treatments, the cut crown roots were revisited to check the vine growth. Average mortality percents of non-treatment (0 g) and salt treatments were 74.1% and 89.2%, respectively. There was an increase in mortality of kudzu as the salt amounts treated in the crown roots increased. Meanwhile, the mortality was negatively correlated with diameter of the crown roots. No further growth was observed in the crown roots at the diameter of 8 cm or less treated with 40 g of salt. The crown roots with salt treatment showed extensive tisse disruption and blackening compared with those of non-treatment. These results suggest that the salt treatment may be a chemical method that could be combined with physical removal of kudzu vines in plantation.
The COVID-19 pandemic has created an enormous disruption to human lives, social activities and economic systems worldwide. The Korean Society of Forest Science (KSFS) has organized virtual or hybrid meetings to share science and out of state-of-the-art technology in the forest or related fields. The topics of monthly virtual seminars were Introduction to dendrochronology, decreasing the number of forest birds in Korea, ecosystem management in USA, smart agriculture: technical trends and model for dissemination to farm field, trends of agriculture, forestry and fishery ODA and plan to expand participation in the forestry sector, climate change story, understanding of biogeography, current situation and challenges on mechanized forestry while a special hybrid seminar on results of UNFCCC COP 26 and response strategy on forest sector was held hybrid. The hybrid annual meeting of KSFS entitled The Value of Forests in the New Normal Era: Peace and Carbon Neutral including a virtual international symposium on Ecosystem Restoration for Green and Peace Asia with the participation of Korea, Philippines, Vietnam, Indonesia, Mongolia, CIFOR, Asian Forest Cooperation Organization (AFoCO), Mekong Institute, and ASEAN Center for Biodiversity (ACB). The 15th World Forestry Congress (theme: Building a Green, Healthy and Resilient Future with Forests) which will be held in Seoul, Korea on 2-6 May 2022 will be an opportunity to strengthen international exchange and cooperation for KSFS.
Learning about the concept of forest ecosystem services (FES) from early childhood will help future generations grow to value and manage forests that are deteriorating globally. This study was developed based on the perspective that picture books about forests can facilitate children’s knowledge about the forests, form positive emotions with them and feel connected, and function as a triggering source to make children act sustainably toward forests. The study employed content analysis to explore the presence and association between environmental themes and FES categories depicted in 169 picture books about forests. The study revealed that compared to other environmental themes and FES categories, themes related to the behavioral domain (e.g., ‘conservation effort’) and regulating services category were less depicted, respectively. In addition, the depiction of regulating, cultural, and supporting services categories were both positively and negatively associated with the depiction of some particular environmental themes. In the following, we discuss several trends that emerged from the analysis and their implications for research and practice.
産業革命以来長期に渡り放出された、化石燃料燃焼等に由来する大気汚染物質は、酸性雨や越境大気汚染問題を引き起こし、その沈着による森林生態系への悪影響が懸念されてきた。物質によっては、大気汚染が改善した後も生態系内で長く循環・保持されており、そのようなレガシー（遺物）が、気象変動により可動化し、物質循環系を撹乱し生態系の回復（例えば酸性化から）を阻害する可能性がある。特に硫黄（S）は、近年まで続いた国内及び越境大気汚染による長期的かつ大量な負荷に加え、土壌に吸着・保持される性質から、大気汚染レガシーが大きいと考えられる。中部日本の太平洋側（伊自良湖）と日本海側（加治川）の森林集水域において、その蓄積と流出の可能性を検討した。伊自良湖では、地質由来のSの影響が大きいが、大気沈着由来のSは土壌・植生系に蓄積しており（Sase et al. 2019, Biogeochemistry）、有機態Sがその多くを占めることが明らかになった（Tanikawa et al. 2022, Geoderma）。1990年代半ばに極端気象とともに見られた河川への急激なS流出は、有機態Sの無機化によると考えられ、今後も同様の現象が生じる可能性とともに、さらなる研究の必要性を示唆した。
