    Abstract PDF
    This study was conducted to obtain information relevant to resolving problems related to artificially introduced plants in ecological restoration projects. We investigated artificially introduced plants and plants growing naturally from its surroundings in the active restoration sites of the Ecosystem Conservation Fund Return Project (ECFRP) of the Ministry of Environment and the Civilian Control Zone Forest Restoration Project (CCZFRP) of the Korea Forest Service. We also analyzed the characteristics of native, exotic, and cultivated plants in addition to their Raunkiaer’s life forms. Furthermore, we compared the planted areas and inhabited areas, as well as the characteristics of the habitats of native plants among the planted plants. We found that among the plants planted in the ECFRP, 50.4% were native, 6.8% were exotic, and 42.9% were cultivated. Meanwhile, in the CCZFRP, 78.6% were native, 21.4% were exotic. We also noted that many native plants were found in the planted areas that were far from their habitats. In addition, we identified many native plants that were planted in areas judged to have characteristics different from that of their natural habitat. In the case of Raunkiaer’s life forms, the planted plants showed high ratios of megaphanerophytes (MM) and microphanerophytes (N), while the invasive plants showed high ratios of therophytes (Th) and hemicryptophytes (H). When restoring the ecosystem, the ratio of planting native plants should be higherthan that of exotic or cultivated plants. Moreover, the habitats and ecological characteristics should be considered when selecting native plants to enhance the effect of ecological restoration.

    Soonju Yu ORD ID , Jong-Kwon Im ORD ID , Lee Bo-Mi ORD ID | 2020, 29(5) | pp.323~337 | number of Cited : 1
    Abstract PDF
    Long-term continuous data were used to investigate changes in air and watertemperature and temperature hysteresis at Lake Paldang, the largest source of drinking water in South Korea. Based on the temperatures at Yangpyeong, near Lake Paldang, using a seasonal Mann-Kendall test, the rate of change of increase in temperature overthe last 27 years (0.060°C/yr, 1993-2019) was higher than that of during 47 years (0.048°C/yr, 1973-2019). The air and watertemperatures in Lake Paldang and its influent rivers had a high correlation (R > 0.9, p < 0.005); however, the water temperature increased atrate slowerthan the river watertemperature, and the watertemperature decreased slowly as the air temperature fell. The depth-averaged water temperature also changed more slowly than the surface water of the lake both when the air temperature was high and when it was low. This is likely because the lake has a larger area and a longer heat retention time than rivers, resulting in a greater hysteresis of water temperature at lake.

    Integrating Urban Planning and Environmental Impact Assessment for Enhancing Citizen Participation : Focusing on Official Development Assistance Project in Kenya

    Yeom Jae Weon ORD ID , Dong Oh, Ha ORD ID , Jung, Juchul ORD ID | 2020, 29(5) | pp.338~349 | number of Cited : 1
    Abstract PDF
    The importance of citizen participation, especially in urban planning, is increasing. Citizen participation is the sharing of control or influence on decisions and choices that affect stakeholders, and providing citizens with the opportunity to participate in the decision-making process. The paradigm of urban planning has also shifted from the rational planning model, which relied solely on the rationality of planners, to expand citizen participation. In fact, citizen participation in the process of establishing a vision for comprehensive plan is expanding, especially in metropolitan governments such as Seoul, Busan, and Daegu. However, there are criticisms that citizen cannot practically participate in urban planning due to limited participation methods and lack of participation in the pre-planning process. Accordingly, the necessity of institutionalization of citizen participation in the urban planning has been raised. According to literature reviews, foreign countries have integrated environmental impact assessment (EIA) into the urban planning to institutionalize citizen participation and pursue sustainability of the plan. In particular, the EIA actively includes citizen participation from the scoping stage to identify the issues. However, it was pointed out that there is a limitation to guaranteeing sustainability of the plan since EIA is carried out only at the urban project level. In other words, in order to expand citizen participation and ensure sustainability through the integrated approach, analysis of EIA in urban planning level is needed. Therefore, this study carried out a case study of EIA in the official development assistance of the Kenya multi-purpose dam construction to analyze the impact assessment in a wider scope than the urban project-level.

    Application of Nano Fe°-impregnated Biochar for the Stabilization of As-contaminated Soil

    Yu-Lim Choi ORD ID , Ganesh Kumar Reddy Angaru ORD ID , Ahn Hyeyoung ORD ID and 4 other persons | 2020, 29(5) | pp.350~362 | number of Cited : 1
    Abstract PDF
    In this study, nano Fe°-impregnated biochar (INPBC) was prepared using pruning residues and one-pot synthetic method and evaluated its performance as an amendment agent for the stabilization of arsenic-contaminated soil. Forthe preparation of INPBC, the mixture of pruning residue and Fe (III) solution was heated to 220°C for 3hr in a teflon-sealed autoclave followed by calcination at 600°C under N2 atmosphere for 1hr. As-prepared INPBC was characterized using FT-IR, XRD, BET, SEM. For the stabilization test of as-prepared INPBC, As-contaminated soils (Soil-E and Soil-S) sampled from agricultural sites located respectively near E-abandoned mine and S-abandoned mine in South Korea were mixed with different of dosage of INPBC and cultivated for 4 weeks. After treatment, TCLP and SPLP tests were conducted to determine the stabilization efficiency of As in soil and showed that the stabilization efficiency was increased with increasing the INPBC dosage and the concentration of As in SPLP extractant of Soil-E was lower than the drinking water standard level of Ministry of Environment of South Korea. The sequential fractionation of As in the stabilized soils indicated that the fractions of As in the 1st and 2nd stages that correspond liable and known as bioavailable fraction were decreased and the fractions of As in 3rd and 4th stages that correspond relatively non-liable fraction were increased. Such a stabilization of As shows that the abundant nano Fe° on the surface of INPBC mixed with Ascontaminated soils played the co-precipitation of As leaching from soil by surface complexation with iron. The results of this study may imply that INPBC as a promising amendments for the stabilization of As-contaminated soil play an important role.

    International Case Study on the Public Participation Procedure in Environmental Impact Assessment

    Jin-Oh Kim ORD ID , BYOUNG WOOK MIN ORD ID | 2020, 29(5) | pp.363~376 | number of Cited : 1
    Abstract PDF
    Various policies and institutional efforts are being made for mature democracy and more sustainable administration of our society. In this respect, the importance of civic participation, considered essential in environmental impact assessment, has been consistently emphasized in the relevant theories and practices. Although various methods and forms of public participation are taking place in Korea, criticism is widely understood that collecting citizens’ opinions in the decisionmaking process has become ineffective and formal. Starting from these issues, this paper seeks to learn lessons from the foreign cases in the international context. Extensive literature review was conducted to examine the meaning and objectives of public participation in EIA and the tactical principles. Based on this, the participatory systems and procedures in the United States, Britain, Germany, Japan, and Canada were critically reviewed, and the implications were derived through specific cases. The results are, first, the provision of specific public participation guidelines, second, the securing of transparency in the decision-making process, third, the expansion of procedural participation levels, and lastly, the guarantee of participation opportunities. This paperis meaningful as a basic study to enrich discussions on public participation in the domestic EIA hoping to help research through more diverse empirical cases in the future.

    A Study on Fauna Habitat Valuation of Urban Ecological Maps

    Min kyu Park ORD ID | 2020, 29(5) | pp.377~390 | number of Cited : 0
    Abstract PDF
    URBAN ECOLOGICAL MAPS must be created by local governments by NATURAL ENVIRONMENT CONSERVATION ACT, and the maps are generally called biotope map. So far, biotope maps study was a tendency to focus on the type of vegetation, naturalness, land use, landscape ecology theories. However, biotope related studies have not reflected the concept of animal habitat, which is a component of biotope, and that is the limitation of biotope map research. This study suggest a methodology to predict potential habitats forfauna using machine learning to quantify habitat values. The potential habitats of fauna were predicted by spatial statistics using machine learning, and the results were converted into species richness. For biotope type assessments, we classified biotope values into vegetation value and habitat value and evaluated them using a matrix for value summation. The vegetation value was divided into 5 stages based on vegetation nature and land use, and the habitat value was classified into five stages by predicting the species richness predicted by machine learning. This is meaningful because our research can positively reflect the results of field surveys of fauna that were negatively reflected in the evaluation of biotope types in the past. Therefore, in the future, if the biotope map manual is revised, our methodology should be applied.

    A Case Study on the Health Impact Assessment of Residential Development Projects

    Moonshik Shin ORD ID , Jong In Dong ORD ID , Jongsik Ha ORD ID | 2020, 29(5) | pp.391~402 | number of Cited : 1
    Abstract PDF
    Health Impact Assessment based on municipal law is performed and written in the sanitary and public health part in the current environmental impact assessment. Residential development projects such as housing site development etc., are not subject to health impact assessment under Article 13 of the Environmental Health Act. However, health impact assessment is conducted partially based on the review that health impact assessment targets which are identified among substances emitted from pollutants nearby industrial complexes should be assessed risk (including carcinogenic and non-carcinogenic) at the stage of the environmental impact assessment consultation. Although residential development projects do not have plans for pollutant emitting facilities that emit hazardous air pollutants, there is a possibility that residents might be affected by pollutants from industrial complex nearresidential area in the future. In this study, Health impact assessment was conducted to examine the impact on residents in planned areas by analyzing previous residential development projects. We predicted future impact by using the literature survey results on surrounding area (case1) and conducting contribution analysis (case2) and predicting exposure concentration of carcinogenic substances applying Atmospheric Diffusion Model (AERMOD). By this study, we concluded that applying on-site survey, contribution analysis and prediction of exposure concentration by using AERMOD complementarily will be effective to assess the health impact to the receptors by pollutants from industrial complexes near the planned zone.
