Exports of Korean non-timber forest products to the Japanese market decreased 46.3% from 17.54 million dollars in 2010 to 9.42 million dollars in 2014. This research aims to find the appropriate strategies for exporting Korean non-timber products, such as chestnut, shitake, persimmon, and wild ginseng. We applied conjoint analysis to investigate the preferences of Japanese homemakers for Korean non-timber products. The results are as follows: (1) There is a clear distinction in the preference for the attributes and levels of products; (2).Korean products are preferred to Chinese products, but have lower competitiveness than Japanese products; (3) Japanese homemakers responded sensitively, not to the forest product prices, but to changes in their specific attributes. These results can be used to promote the export of Korean non-timber products to the Japanese market.

Since forest trees form the basis of forest ecosystem, their prolong subsistence is crucial for various flora and fauna. The foremost challenges to sustain the forest ecosystem comprise of the declining forest tree population accompanied with structural changes due to afforestation and exploitation of forest area, environment changes, pests, pollution, and introgressive hybridization. For ex situ conservation approach, in vitro techniques encompass basic role for conserving tree genetic resources, predominantly where natural propagules like recalcitrant seed might not be appropriate for long-term conservation. The practice includes restricted growth techniques, conventional micropropagation, production and storage of synthetic seeds, and cryopreservation. Even though these practices have been applied chiefly to herbaceous species, but recently, woody species were also focused upon. Key conceptions, challenges and techniques for forest tree seed conservation are discussed briefly in this review with special emphasis on some successful cryopreservation approaches for long-term storage.

The purpose of this study is on monitoring complementary forest of village according to restoration project. Accordingly, this study was accomplished in case of Dubang complementary forest of village in Wanju-gun which was indicated as beautiful village forest by Korean government. This study describes the restoration project and identifies the change of species diversity and succession through monitoring. For this, vegetational survey was performed in 2003 and 2010. D(Dominant degree) and S(Sociability degree) was measured by Brown-Blanquet's method. The results demonstrate significant increase of species diversity and progress of natural succession. It means ecological structure and function have improved. Also ecological disturbance appears here and there on account of insufficient management.

This study is design to provide basic directions that Korea can take in forestry negotiation of Korea- Vietnam FTA. Trade trends and characteristics of forestry sector are figured out and the competitiveness of main products are analyzed. The trade amount between Korea and Vietnam is $207,260 thousand. Korea exports nontimber products to Vietnam, while she mainly imports wood products. The average import value of wood products during recent five years accounts for 88% of all value from Vietnam. The export items are not various, and the export value is small. The amount of imports, however, which are mainly composed of low price wood products, is relatively big. The results of analysis say that three items of Korean forest products have competitiveness, while Vietnam has eleven items. According to the study it is recommended that a sawn wood and a plywood should be classified as sensitive products to minimize and to take a long term tariff reduction.

During the COVID-19 pandemic, the online agricultural and food products market has experienced substantial expansion. This study aims to examine the factors influencing consumers' online purchasing behavior, their satisfaction levels regarding price and quality, the frequency of online transactions, and their future purchasing intentions concerning key short-term non-timber forest products. The analysis is based on survey responses obtained from 1,000 consumers across the nation. Results reveal that while online purchasing of non-timber forest products may not be as active compared to other sectors, various consumer behavior characteristics such as online purchase experience, socio-economic variables, online purchase dependency, and information utilization significantly influence purchasing decisions. These findings shed light on the understanding of consumer behavior through online platforms, particularly in non-timber forest products where analytical attempts have been relatively scarce compared to other agricultural products. The insights derived from this analysis could serve as fundamental data for understanding online consumption patterns, especially in sectors where research on consumer behavior remains limited. To expand the consumption of short-shelf-life perishable goods, which relatively have lower online consumption compared to other fresh agricultural products, it is necessary to conduct analyses that identify the socioeconomic characteristics and corresponding needs of consumers. Additionally, analyses should be conducted to explore the potential for developing and utilizing processed foods for online consumption. These analyses should be carried out in conjunction with an understanding the socio-economic characteristics identified in this study.

Considering irrigation facilities are currently insufficient and drought vulnerability due to climate change is high, efficient measures are required to secure water supply for field crops. This study, therefore, calculated the water shortage to secure water for representative field crops. An economic analysis was further conducted by comparing the production income to the input cost for each method. Here, five distinct regions were selected to represent each crop-Cheongyang-gun for chili peppers, Yesan-gun for apples, Dangjin-si for cabbages, Seosan-si for garlic, and Goesan for beans. The regions with insufficient water supply were estimated by calculating the water requirements and the supplied water from public groundwater wells for each area. A comprehensive set of four scenarios was presented as a strategy to ensure water security and manage irrigation facilities. These scenarios comprised the maintenance of existing groundwater wells, the construction of new water storage tanks, the installation of additional groundwater wells, and the utilization of surface water. B/C (benefit/cost) analysis was conducted for each scenario. As a result, the construction of water storage tanks was selected as a facility and water management plan in Cheongyang-gun, Dangjin-si, and Seosan-si. The analysis additionally indicated the economic viability of installing surface water utilization facilities in Yesan-gun and developing water storage tanks and groundwater (aquifer) wells in Goesan-gun. The results of this study are considered to serve as foundation data that may be utilized in the selection of water management plans for drought-prone areas in the future.

In this study, the economic feasibility of a local energy facility that uses forest biomass as an energy source was assessed. We analyzed profitability using data from the Forest Energy Self-sufficient Village Project financed by the Korea Forest Service. The energy facility has a cogeneration generator and wood chip boiler. Wood chip, which has lower heat value and is cheaper than wood pellets, is used as fuel. Revenue comes from the sale of electricity, heat, and renewable energy certificates. Additionally, we considered the sale of carbon credits as substitutes for fossil fuels. The expenditure consists of fuel costs and fixed costs, and the initial investment is treated as a sunk cost. Under the condition of a 55% operation rate and wood chip price of 95,000 KRW per ton, the annual net revenue is positive. Crucial factors for managing the facility sustainably are operation rate and fuel cost. A simulation in which two factors were changed showed that the annual net revenue is negative with a 50% operation rate and 100,000 KRW per ton of wood chip price. To improve net revenue, an increase in the operation rate or a decrease in the wood chip price is required. Additionally, selling carbon credits will make the operation of the facility more profitable. Furthermore, the payment required to procure wood chips could contribute to the rural economy. To foster the use of forest biomass for energy, the price for heat supplied from renewable energy sources should be subsidized.
