  • Green Infrastructure has been considered as one of strategies for flood mitigation in cities. Although, the diverse benefits of green infrastructure implementation are studies, there is a lack of research on the relationship between spatial composition and configuration of green infrastructure and urban flood mitigation. To address this gap, this study 1) utilized high-resolution satellite imagery to analyze spatial composition and configuration of green infrastructure in highly developed seven cities in South Korea, and 2) conducted an empirical analysis to find the relationship between economic losses from flooding and spatial patterns of green infrastructure and development patterns. The results of this research will be helpful for urban planners to prepare green infrastructure implementation guidelines for effective urban flood mitigation.

  • Urban forests provide great ecosystem services to population in metropolitan areas even though they occupy little green space in a huge gray landscape. Unfortunately, urbanization inherently results in threatening the green infrastructure, and the recent urbanization trends drew great attention of scientists and policy makers on how to preserve or restore green infrastructure in metropolitan area. For this reason, mapping the spatial distribution of the green infrastructure is important in urban environments since the resulting map helps us identify hot green spots and set up long term plan on how to preserve or restore green infrastructure in urban environments. As a preliminary step for mapping green infrastructure utilizing multi-source remote sensing data in urban environments, the objective of this study is to map vegetation volume by fusing LiDAR and multispectral data in urban environments. Multispectral imageries are used to identify the two dimensional distribution of green infrastructure, while LiDAR data are utilized to characterize the vertical structure of the identified green structure. Vegetation volume was calculated over the metropolitan Chicago city area, and the vegetation volume was summarized over 16 NLCD classes. The experimental results indicated that vegetation volume varies greatly even in the same land cover class, and traditional land cover map based above ground biomass estimation approach may introduce bias in the estimation results.

  • The purpose of this study is to propose the methodology for introducing green infrastructure that can improve the health of citizens by promoting walkability. The methodology is composed of the following three phases: classification of the types of green spaces, selection of core green spaces with two separate analyses, and introduction of the framework of green infrastructure to promote walkability. In the first phase, the classification of the types of green spaces was carried out in order to understand existing distribution pattern of green spaces in study site. In the second phase, walkable blocks were selected by such methods as walkability value. Through these two analyses, all the blocks were divided into three groups according to the ranking figured up the second analyses' results. The blocks in the first group, the group involved in the top 30% and having the greatest ranking, were defined as walkable blocks. In the last phase, a basic frame of the green infrastructure in study site was introduced by connecting the walkable blocks with using other blocks and the green spaces over 1ha. In case study, 28 important green spaces and 35 walkable blocks were selected through the two analysis process. Then, the basic framework of green infrastructure based on the selected 28 important green spaces and 35 walkable blocks was introduced. The methodology applied to this study can be used to get the best selections of the proper green infrastructure in accordance with the purpose of the ecological and recreational local development. In particular, this study will suggest a specific analysis model to use for the ecological and walkable urban planning with green spaces existing in the city.

  • The "Green Policy" of Korean government is classified as three categories, the first is 'reduction of fossil fuel use', the second is 'clean energy development' and the last is 'sustainable green property which has a continuous value in the use'. In this matter, this study provides how the green property concept include green infrastructure and how to link the green infrastructure to effective geo-spatial management by cadastre system. The establishment of green infrastructure is not a simple procedure, but definitely starts from the cadastre system. If the green policy includes sustainable way of land/marine use, the green cadastre is significant because of its possibilities to be used as a powerful implementation.

  • 녹색 인프라 구축이란 정원, 공원, 녹지, 하천, 습지, 농경지, 그린벨트 등을 녹색길로 연결하여 네트워크를 형성하는 것을 의미한다. 녹색 인프라는 인간은 물론 환경에도 유익한 기능과 편익을 제공하고, 건강하고 활기찬 지역사회를 만드는데 기여한다. 수질관리 측면에서도 녹색 인프라는 강우유출수를 저류하고, 비점오염물을 저감시키는 장점이 있다. 녹색 인프라에 대한 이런 장점과 편익이 알려지면서 환경 선진국에서는 도시 및 지역 개발에 녹색 인프라를 적극적으로 활용하고 있다. 국내의 경우 회색 인프라 위주의 국가 건설정책으로 가뭄, 홍수, 산사태 등 자연재해 발생, 수질과 대기 질 악화, 생물다양성의 저하, 지역경제 활성화 저해 등 다양한 환경적 경제적 문제를 야기하고 있다. 이들 문제를 해결하기 위해서는 정부 차원에서 녹색 인프라 구축에 대한 정책의 수립과 수행이 필요하다. 녹색 인프라 구축에 관한 미국의 사례와 국내의 상황의 분석을 통하여, 녹색 인프라를 구성하는 40개의 항목을 추출하였고, 국내에 적용 가능한 녹색 인프라 구축 정책수단으로 공공부문 5개와 민간부문 4개를 제시하였다. 녹색 인프라 구축을 위한 법안과 관련법의 개정안을 제안하였고, 녹색인프라를 확충할 수 있는 방안들을 제시하였다.

  • The accelerated pace of climate crisis due to continuous industrialization and greenhouse gas emissions necessitates sustainable solutions that simultaneously address mitigation and adaptation to climate change. Naturebased Solutions (NbS) have gained prominence as viable approaches, with Green Infrastructure being a representative NbS. Green Infrastructure involves securing green spaces within urban areas, providing diverse climate adaptation functions such as removal of various air pollutants, carbon sequestration, and isolation. The proliferation of Green Infrastructure is influenced by the quantification of improvement effects related to various projects. To support decision-making by assessing the climate vulnerability of Green Infrastructure, the U.S. Department of Agriculture (USDA) has developed i-Tree Tools. This study proposes a comprehensive evaluation approach for climate change adaptation types by quantifying the climate adaptation performance of urban Green Infrastructure. Using i-Tree Canopy, the analysis focuses on five urban green spaces covering more than 30 hectares, considering the tree ratio relative to the total area. The evaluation encompasses aspects of thermal environment, aquatic environment, and atmospheric environment to assess the overall eco-friendliness in terms of climate change adaptation. The results indicate that an increase in the tree ratio correlates with improved eco-friendliness in terms of thermal, aquatic, and atmospheric environments. In particular, it is necessary to prioritize consideration of the water environment sector in order to realize climate change adaptive green infrastructure, such as increasing green space in urban areas, as it has been confirmed that four out of five target sites are specialized in improving the water environment.

  • Fine particulate matter (PM2.5) has been the biggest environmental problem in Korea since the 2010s. The present study considers the value of urban forests and green infrastructure as an ecosystem service (ES) concept for PM2.5 reduction based on satellite and spatial data, with a focus on Seoul, Korea A method for the spatial ES assessment that considers social demand variables such as population and land price is suggested. First, an ES assessment based on natural environment information confirms that, while the vitality of vegetation is relatively low, the ES is high in the city center and residential areas, where the concentration of PM2.5 is high. Then, the ES assessment considering social demand (i.e., the ESS) confirms the existence of higher PM2.5 values in residential areas with high population density, and in main downtown areas. This is because the ESS of urban green infrastructure is high in areas with high land prices, high population density, and above-average PM2.5 concentrations. Further, when a future green infrastructure improvement scenario that considers the urban forest management plan is applied, the area of very high ESS is increased by 74% when the vegetation greenness of the green infrastructure in the residential area is increased by only 20%. This result suggests that green infrastructure and urban forests in the residential area should be continuously expanded and managed in order to maximize the PM2.5 reduction ES.
