In this study, we investigated the effect of carbon sequestration and sink on the environmental impact assessment of a Bogeumjari Housing Project. Through the case study, we found that, if the project is implemented, the amount of carbon stock tends to decrease greatly whileas the amount of the carbon emission tends to greatly increase. Furthermore, we found that the future land use should be planned in detail in order to maintain the soil carbon stock prior to development. Also, enlargement of undeveloped forest land area would be more efficient than that of newly planted area in terms of carbon sequestration.

In general, carcass disposal causes environmental, economic, and social damages, which deteriorates the quality of life in rural areas. Contagious animal diseases such as foot and mouth disease and avian influenza havebeen occurring steadily until now, and it causes a burden on the ongoing construction and management of burial sites. However, in Republic of Korea, the current management of carcass disposal mainly focuses on the post-environmental monitoring, and there is not enough active measures to minimize the various damages. The objective of this project is to promote environmental welfare in therural areas by providing active alternatives in order to minimize diverse and complex environmental-economic-social damages. In this study, based on the results of environmental, socio-economic damages caused by carcass disposal derived in the first year, we analyzed the cause of each damage in details and analyzed the cause of damage. In addition, we have developed a management direction that minimizes damages from the carcass disposal with comprehensive diagnosis of damage-causes. According to the comprehensive causal map that compiles the harms and causes of environment, economy and social sector, the causes are simply based on the fact that the guideline is not appropriate or the guideline implementation is not enough, while the damage is complex and diverse. Therefore, we devised an assessment tool which can diagnose environmental-economic-social-potential damage in order to judge damage objectively and collectively. As a result of applying to the representative case area, the degree of damage in the adjacent villages was different when the same environmental conditions were used. In addition, the residents of livestock burial area showed significantly lower satisfaction on health, welfare, settlement life, environment, and landscape than the residents of other areas. In conclusion, we propose three directions of the carcass disposal management policy to improve the local residents’ quality of life by minimizing the damages of carcass disposal. First, the government should make a policy that fuses economic and social management centered on environmental management. Second, the potential damage management should be strengthened by developing policy measures to effectively manage the unexplained damage associated with the livestock environment, selection of burial sites, cultural tourism, and governance. Third, it is necessary to promote the hybrid policy that harmonizes the environmental and economic damage management policies led by the central government and the social damage management policies led by the municipalities Do The results of this study can be used for the future diagnosis of damage caused by carcass disposal, determination of local customized management priorities, and policy development for improvement of the buried area’s quality of life.

In this study, we investigated the effect of carbon sequestration and sink on the environmental impact assessment of a housing redevelopment project. Through the case study, we found that the amount of carbon sequestration and sink increased with the increase of the area of park and green space and, furthermore, the amount of carbon emission decreased slightly with implementation of district heating and renewable energy. Therefore, it is necessary for its land use plan to be established to minimize the amount of net carbon emission, taking account of both the amount of present carbon emission and the amount of the future carbon sink, sequestration, and emission.

To apply the Convention on Biological Diversity(CBD), Korea has developed the 3^rd NBSAP and applied relevant Aichi Targets so far. However, as CBD keep announces new tasks and decisions based on parties’ debate and consent,there is a need to follow-up those negotiations of international meeting and seek the ways to apply it at national scale. In this vein, our study developed and applied the ‘planning and operation of support programs for the implementation of the CBD’,which is consisted of four tasks. First of all, through participating and analyzing the SBSTTA21, this study identified main priorities and gap to apply the latest agenda for national implementation. In specific, SBSTTA21 suggests the ways to develop ‘follow-up strategy after 2020’. Issues including 2050 biodiversity vision and scenario, linkage between SDGs and Aichi Target, biodiversity mainstreaming in industrial health sector, GB05 and evaluation tool for policy effectiveness were discussed. In this report, main opinions and debates of participated parties were analyzed. To point out, parties decided to keep the 2050 vision ‘the harmony with nature’. Furthermore, the importance of scenario and its consideration on multiple policy strategies were emphasized. In addition, as for the biodiversity mainstreaming, which has been discussed in the production sectors, has been grounded in the industrial and health sectors. In this vein, new range of discussions on national and regional plans, environmental impact assessment, strategic environmental impact assessment, and spatial planning were posed. Moreover, evaluation tools for the assessment of policy effectiveness and preparation plans for GB05 were suggested. Such issues discussed at SBSTTA21 will serve as a milestone to develop the final decision at COP 14. Second, as our progress on biodiversity finance are still need some improvements, this report analyzed the trend on national biodiversity expenditure. In specific, the total national expenditure on biodiversity at 2015 was identified. The results indicated that size of biodiversity finance was increased compared to 2014. Furthermore, the characteristics of biodiversity finance on forest sector were evaluated. This report show that, as finance is generally planned at project-level, each project should be analyzed to examine positive and negative impact on biodiversity conservation and its sustainable use. Third, to promote technical and scienti五c cooperation and participation of diverse stakeholder, biodiversity network was developed and knowledge- exchange was facilitated. In specific, within ASEAN member countries, best practice and major national policy on bio-economy and natural resources management were discussed. In case of China, ‘the role of NGOs for the implementation of the Aichi Target5 and 6 follow-up strategies after 2020’ were discussed. Furthermore, main activities of major NGOs in Korea, China and Japan to implement CBD were introduced and the ways to expand the NGO’s role were suggested. Lastly, to promote diverse stake holder’s participation, this project also performed knowledge-exchange with several NGOs and biodiversity specialist of sub-national governments at national level. We expect that our project will provide the major information for the development of 4th NBSAP. The analysis on SBSTTA21 will offer the new directions and priorities to apply the latest decisions of CBD. Moreover, our analysis and activities on biodiversity finance and knowledge exchange will contribute to facilitate the national implementation. To further promote the biodiversity conservation and its sustainable use, and to facilitate transformational change and biodiversity mainstreaming, there is a need to keep planning and operation of various support programs for the implementation of the CBD.

먹이연쇄 생물축적 모형을 이용한 잔류유류오염물질의 생태위해성평가

황상일(Sang Il Hwang),권정환(Jung Hwan Kwon) 大韓環境工學會 2009 대한환경공학회지 Vol.31 No.11

유류 유출에 의한 잔류 석유계 오염물질들은 높은 소수성으로 인하여 해양 저서 생태계에 축적될 수 있다. 오염 피해를 입은 지역의 생태위해성평가를 위해서는 통상적으로 많은 모니터링 자료가 필요하다. 간단한 먹이연쇄 생물축적 모형을 이용하여 생태계의 잔류 유류오염물질에 대한 노출수준의 평가를 통해서 모니터링에 소요되는 시간과 비용을 크게 절약할 수 있다. 본 연구에서는 네 종류의 다환방향족탄화수소(페난트린, 안트라센, 피렌, 벤조[a]피렌)에 대하여 가상의 저서생태계를 대상으로 두 개의 노출 시나리오에 대하여 이들 오염물질의 잔류농도를 산정하였다. 해수 중 농도를 수용해도의 1/10에 이르는 것으로 가정한 극단적인 시나리오에서 체내 잔류농도는 영양단계에 따라 차이가 있으나, 5~250 mg/kg으로 예측되었다. 또한 대상 생물종들에 대하여 주어진 조건에서 생물농축계수(BCF)와 생물축적계수(BAF)를 평가하였다. 대사과정을 무시할 경우 로그 생물농축계수(log BCF)는 로그 옥탄올-물 분배계수(log KOW)가 7.0에 이를 때까지 log KOW의 증가에 따라 선형적으로 증가하였고 7.0 이상의 값에서는 점차 감소하였다. 대상생태계에서의 생물증폭 현상은 log KOW값이 5.0 이상인 물질에서 두드러졌으며, 이는 많은 석유계 오염물질들의 log KOW값이 5.0 이상이므로 오염피해를 입은 생태계내의 생물증폭현상을 예측하기 위해서는 먹이연쇄망의 구조가 매우 중요함을 나타낸다. 지역특이적 노출평가를 위해서는 추가적 연구가 필요하나, 현 상태의 모형은 스크리닝 수준에서의 저서 생태계의 잔류 유류오염물질에 대한 노출을 평가할 수 있을 것으로 사료된다. Residual petroleum hydrocarbons after an oil spill may accumulate in the marine benthic ecosystem due to their high hydrophobicity. A lot of monitoring data are required for the estimation of ecosystem exposure to residual petrochemicals in an ecological risk assessment in the affected region. To save time and cost, the environmental exposure to them in the affected ecosystem can also be assessed using a simple food-web bioaccumulation model. In this study, we evaluated residual concentrations of four selected polycyclic aromatic hydrocarbons (phenanthrene, anthracene, pyrene, and benzo[a]pyrene) in a hypothetic benthic ecosystem composed of six species under two exposure scenarios. Body-residue concentration ranged 5~250 mg/kg body depending on trophic positions in an extreme scenario in which the aqueous concentrations of PAHs were assumed to be one-tenth of their aqueous solubility. In addition, bioconcentration factors (BCFs) and bioaccumulation factors (BAFs) were evaluated for model species. The logarithm of bioconcentration factor (log BCF) linearly increased with increasing the logarithm of 1-octanol-water partition coefficient (log KOW) until log KOW of 7.0, followed by a gradual decrease with further increase in log KOW without metabolic degradation. Biomagnification became significant when log KOW of a pollutant exceeded 5.0 in the model ecosystem, indicating that investigation of food-web structure should be critical to predict biomagnifications in the affected ecosystem because log KOW values of many petrochemicals are higher than 5.0. Although further research is required for better site-specific evaluation of exposure, the model simulation can be used to estimate the level of the ecosystem exposure to residual oil contaminants at the screening level.

Selecting the Best Soil Particle-Size Distribution Model for Korean Soils

황상일 ( Sang Il Hwang ) 한국환경연구원 2003 환경정책연구 Vol.2 No.1

Particle-size distributions (PSDs) are widely used for the estimation of soil hydraulic properties. The objective of this study was to select the best model among the nine PSD models with different underlying assumptions, by using a variety of Korean soils. The Fredlund model with four parameters, the logistic growth curve, and Weibull distribution model showed the highest performance compared to the other models with the majority of soils studied. It was interesting to find that the logistic growth function with no fitting parameters showed a great fitting performance.
