  • Forest ecosystem provides variety goods and services for human being. Unlike goods, forest ecosystem services could not be easily priced by market mechanism. This uncertainty has been caused to conflict in decision-making related forest ecosystem services. Quantification of forest ecosystem services is required to understand the importance of ecosystem services and their contribution to decision-making. As a growing concern of climate change, it is necessary to quantify and calculate carbon storage and sequestration in forest. In this study, for quantifying carbon storage and sequestration, we compared scale, output, input data availability of the models and analyzed the applicability of the models to Korea. The results of this study show that most models are applicable for quantifying carbon storage and sequestration. However, relatively few models are applicable for other regulating services (air quality regulation, flood mitigation, erosion control, water quality, etc.) of forest. This study would be helpful for quantifying regulating services of forest ecosystem research.

  • This study assessed the water provisioning and climate mitigation ecosystem services of the urban forest in Seoul and Gyeonggi-do. The ecosystem service assessment is conducted based on natural function, natural function and population, and natural function and the beneficiary of the ecosystem service. Then, the impact of climate change on ecosystem services is analyzed to figure out the sensitivity of the impact on the beneficiary when the natural function of forest destroys under climate change. Gyeonggi-do has higher function-based water provisioning ecosystem service than Seoul. And population-based water provisioning ecosystem service appears to be higher in the densely populated area. On the other hand, beneficiary-based water provisioning ecosystem service by applying both natural water supply function and beneficiary distribution appears different with the result of population-based water provisioning service assessment. In other words, regions with high beneficiary population show higher ecosystem service than those with a low beneficiary population even though they have the same water storage function. In addition, climate change has a negative impact on the water provisioning ecosystem service. Under climate change, water provisioning service is expected to decrease by 26%. For climate mitigation service, regions close to the forest seem to have a low temperature, which indicates their high climate mitigation service. The center of the city with high beneficiary population shows high beneficiary-based ecosystem service. The climate change impacts the forest growth to decrease which affect the beneficiary-based climate mitigation ecosystem service to decrease by 33%. From this study, we conclude that beneficiary-based function and ecosystem service assessment is needed as well as the supply-based classification of forest function suggested by Korea Forest Service. In addition, we suggest that not only supply-based function classification and ecosystem service assessment but also beneficiary-based function classification and ecosystem service assessment is needed for managing the urban forest, which has been destroyed by climate change. This will contribute to revaluing cases where a forest with low natural function but high beneficiary-based ecosystem service, which is not considered under the current forest function-based assessment system. Moreover, this could assist in developing a suitable management plan for the urban forest.

  • Using the structural equation model (SEM), this paper investigated the relations between the recognition of forest ecosystem services and the pro-environmental behavior with personal environmental commitment and environmental consciousness. The research data was collected from April 11 to 21, 2019, as an online survey by residents in Korea. 425(91.4%) of the total 465 copies were used as final analysis data, excluding insincere responses. Results showed that most respondents recognized forest ecosystem services as positive and recognition of forest ecosystem services has a positive impact on both environmental commitment and environmental consciousness. Moreover, cultural services positively affected both constructs more than supply and control services. The most significant total effect was the path of 'cultural services-environmental commitment-pro-environmental behavior'. Environmental commitment is more effective in inducing the behavior than environmental consciousness to those who consider forest ecosystem services significant. Even if forest ecosystem services are recognized as important, those with experience of commitment to the natural environment would have more intention of pro-environmental behavior. In conclusion, this study is meaningful in that it identified the hypothesized path relationship between the recognition of forest ecosystem services and the pro-environmental behavior and analyzed the antecedent factors.

  • Ecosystem services provide various benefits to human beings, but are considered to be free of cost. To protect ecosystems in an economically sustainable way, several developing countries have adopted a policy known as the Payment for Ecosystem Services (PES) that compensates upstream services with monetary incentives collected from service users. Vietnam is one of the countries that have enacted a nationwide PES policy. However, the policy in Vietnam requires further development in order to evaluate the spatial priority zones based on the quantification of ecosystem services. To obtain a recent and high-quality land cover map, we first classified the land cover in the Da River basin, in northern Vietnam, using Landsat dataset. We then applied a water balance theory and an USLE equation to assess hydrological ecosystem services concerning water supply and sediment retention. Following the assessment, we identified the priority areas for hydrological ecosystem services exclusively for forest environments. We found that the quantity and distribution of services from forests varied, due to the topography, climate, and land cover. According to a quantile distribution, Mt. Phu Luong, Mt. Fansipan, and Hoang Lien National Park were evaluated as high service areas in terms of both water yield and sediment retention. As a result, this assessment method can help construct spatial priority zones concerning ecosystem service distribution, and can also contribute to benefit sharing by indicating which forest and landowners require compensation.

  • The concept of ecosystem services is important for the effective management of regional ecological resources. Multiple ecosystem services provided by regional ecosystems are represented as ecosystem service bundles, which define the co-occurrent ecosystem services in a specific region. Bundles provide useful information to identify regional characteristics of ecosystem services and categorize sub-regions with similar patterns of ecosystem service provision. We assessed eleven ecosystem services using modeling approaches and statistical data and produced bundles of cities in Gyeonggi-do.We also conducted principal component analysis and cluster analysis to categorize these cities according to the characteristics of ecosystem services. The results indicated that the cities in Gyeonggi-do were categorized into three groups depending on the types of provision,regulation, and cultural services, and were designated as urbanized, urban-forest, agriculture, or forest cities. These groups were influenced by land use patterns reflecting regional social-environmental features. The results provide useful information for identifying regional ecosystem services and facilitate decision-making in regional ecosystem service management.

  • The aim of this study is 1) to design an auction-type and area-based payments for ecosystem services (PES) in application to private forest in Korea, 2) to develop the framework of index to implement the PES program proposed, and 3) to examine the feasibility and validity of the index framework by conducting a case study. The index framework measures quantities of ecosystem services currently supplied, improvement of ecosystem services anticipated from the proposed management activities, and real implementing costs of the program. The total scores from the case study vary from 301 to 501 for site 1, Goesan-gun and 273 to 460 for site 2, Pyeongchang-gun, respectively, indicating that total index score - measurement of cost-effectiveness - can be varied by the levels of management and real cost even if the scores from ecosystem service indicator group are the same. The index framework which can locate a cost-effective program has significant policy implication given the budget constraints in biodiversity/ecosystem services policy arena.

  • As biodiversity and climate change have become main issues in recent times, the role of the forest ecosystem has been more important and forest conservation has been highlighted. The purpose of this study is to estimate forest area with high conservation values in Gapyung-gun by considering forest ecosystem services. The indicators of biodiversity, climate regulation, and water regulation were selected for assessment in this study. To assess biodiversity, habitat structural features and distribution characteristics of species were analyzed. Climate regulation and water regulation were assessed through analysis of carbon absorption volume and water storage. The result showed that, 50.1% of the forests in Gapyung-gun had high conservation values. The results were verified by comparing them with distribution tendencies of other environmental maps, which represent forest ecological values, and showed similar distribution tendencies. The study was conducted on only Gapyung-gun in Korea; however, the methods used in this study could be utilized for assessment of other areas to identify forests with high conservation values.
