  • Cities in Korea have rapidly urbanized and they are not well prepared for natural disasters which have been increased by climate change. In particular, they often struggle with urban flooding. Recently, green infrastructure has been emphasized as a critical strategy for flood mitigation in developed countries due to its capability to infiltrate water into the ground, provide the ability to absorb and store rainfall, and contribute to mitigating floods. However, in Korea, green infrastructure planning only focuses on esthetic functions or accessibility, and does not think how other functions such as flood mitigation, can be effectively realized. Based on this, we address this critical gap by suggesting the new green infrastructure planning framework for improving urban water cycle and maximizing flood mitigation capacity. This framework includes flood vulnerability assessment for identifying flood risk area and deciding suitable locations for green infrastructure. We propose the use of the combination of frequency ratio model and GIS for flood vulnerability assessment. The framework also includes the selection process of green infrastructure practices under local conditions such as geography, flood experience and finance. Finally, we applied this planning framework to the case study area, namely YeonJe-gu an Nam-gu in Busan. We expect this framework will be incorporated into green infrastructure spatial planning to provide effective decision making process regarding location and design of green infrastructure.

  • 확률강수량은 하천, 하수도, 재해관련 시설 계획 등 각종 물 인프라를 계획하기 위한 기초 자료로 활용되고 있다. 최근의 기후변화 양상을 고려할 때, 지역적으로 다양하게 변화되는 강수패턴은 확률강수량 산정에 있어서도 영향을 미칠 것으로 예상된다. 이 연구에서는 현재 물 인프라 계획에 사용되는 확률강수량의 적용실태를 분석하였으며, 기후변화 영향이 점차 증가할 것으로 보이는 미래의 물 관련 인프라를 건설하거나 시설 개선에 사용되는 확률강수량이 미래 예측 강수를 고려하는 경우에 어떻게 변화되는지를 연구하였다. 인천관측소 지점을 대표 분석 지점으로 선정하여 연강수량, 일최대강수량을 제시하였으며, 기존 확률강수량을 검토하였다. 또한, 인천관측소 지점의 1961~2015년의 분단위 자료를 이용하여 임의시간에 따른 1440분 최대강수량을 산정하였으며, RCP 2.6, 4.5, 6.0, 8.5 시나리오에 따른 2016~2100년 기간의 미래 예측 강수자료에 고정시간-임의시간 환산계수를 적용하여 빈도별 확률 강수량을 산정하였다. RCP 기후변화 시나리오에 의한 미래 예측 강수를 적용한 경우와 과거 관측 자료만을 이용한 확률강수량의 차이를 분석한 결과, 편의보정 여부와 관측지점 및 확률빈도에 따라 결과에 상당한 차이가 발생하였다. 향후 물인프라 계획에 있어서는 미래 예측 강수의 패턴과 지역적 특성 등을 여러 측면으로 고려한 계획을 수립하는 것이 지속가능한 물 관리에 필요한 것으로 판단된다.

  • Green infrastructure planning represents landscape planning measures to reduce particulate matter. This study aimed to derive factors that may be used in planning green infrastructure for particulate matter reduction using text mining techniques. A range of analyses were carried out by focusing on keywords such as 'particulate matter reduction plan' and 'green infrastructure planning elements'. The analyses included Term Frequency-Inverse Document Frequency (TF-IDF) analysis, centrality analysis, related word analysis, and topic modeling analysis. These analyses were carried out via text mining by collecting information on previous related research, policy reports, and laws. Initially, TF-IDF analysis results were used to classify major keywords relating to particulate matter and green infrastructure into three groups: (1) environmental issues (e.g., particulate matter, environment, carbon, and atmosphere), target spaces (e.g., urban, park, and local green space), and application methods (e.g., analysis, planning, evaluation, development, ecological aspect, policy management, technology, and resilience). Second, the centrality analysis results were found to be similar to those of TF-IDF; it was confirmed that the central connectors to the major keywords were 'Green New Deal' and 'Vacant land'. The results from the analysis of related words verified that planning green infrastructure for particulate matter reduction required planning forests and ventilation corridors. Additionally, moisture must be considered for microclimate control. It was also confirmed that utilizing vacant space, establishing mixed forests, introducing particulate matter reduction technology, and understanding the system may be important for the effective planning of green infrastructure. Topic analysis was used to classify the planning elements of green infrastructure based on ecological, technological, and social functions. The planning elements of ecological function were classified into morphological (e.g., urban forest, green space, wall greening) and functional aspects (e.g., climate control, carbon storage and absorption, provision of habitats, and biodiversity for wildlife). The planning elements of technical function were classified into various themes, including the disaster prevention functions of green infrastructure, buffer effects, stormwater management, water purification, and energy reduction. The planning elements of the social function were classified into themes such as community function, improving the health of users, and scenery improvement. These results suggest that green infrastructure planning for particulate matter reduction requires approaches related to key concepts, such as resilience and sustainability. In particular, there is a need to apply green infrastructure planning elements in order to reduce exposure to particulate matter.

  • Recently, interest and financial investment in community infrastructure have been growing. Accordingly, Korean Ministry of Land, Infrastructure and Transport suggested a standard for community infrastructure planning. The standard was based on time distance which represents citizens' accessibility to infrastructure facilities. This paper presents a method to use the navigation application programming interface (API) to calculate travel time. Buffer analysis using Euclidean distance has been widely used so far to evaluate accessibility. However, this method has limitation in that it does not reflect situations in the real world such as crosswalks and slope ways. The infrastructure accessibility indices of local towns in Yeonsu-gu, Incheon were computed based on the time obtained by navigation API. Also, Yeonsu-gu was spatially analyzed to reveal the resident units that are marginalized from community infrastructure facilities. Using navigation API enables to compute realistic accessibility indices and to find unbenefitted residential areas. The method presented in this paper can help community infrastructure planners for their facility spatial plan and budget distribution.

  • This study suggests the method of green infrastructure (GI) application which helps proper distribution of structural GI and non-structural GI by using land characteristics assessment and performs the case study. Land assessment standard consists of land cover type, fragmentation degree, proximity degree to residential districts, and cluster degree of fragmented areas which represents the quality of green network. The result of assessment proposes the land suitability to preserve or develop and it can be utilized to choose the type of the green infrastructures.

  • Strategies for parks and open spaces in the 21st century have moved from focusing on specific elements, such as quantitative growth and ecological and recreational aspects, to green infrastructure, which refers to a multi-functional network of open and green spaces offering a range of benefits. In the case of London, green infrastructure is realised as an integral part of urban infrastructure, involving physical and social infrastructure as well as practical spatial planning at the local level within statutory urban planning as part of a continuously developing green infrastructure framework with a theoretical basis. Taking this perspective, the present study looks at alterations to and developments in green infrastructure policies in the London Plan, the green grid framework as detailed in the city's strategic implementation of green infrastructure. Various trends and characteristics of the policies adopted in the London Plan and some implications are deduced, with three main results being identified. The first is a clear division of roles among the national government, Greater London Authority and borough councils, with local plans established under the guidance of the National Planning Policy Framework (NPPF) and the London Plan. Green infrastructure policies in the London Plan have been applied at a high rate in the boroughs' local plans, which leads to another, linked point. Secondly, green infrastructure policies and the green grid as an implementation framework have been consistently extended and developed through consolidating the London Plan, despite the change of government. Finally, in order to achieve the London Plan, the Mayor of London implemented policies by partnership and supporting programmes for London boroughs. Recently, the Seoul Metropolitan Authority introduced a parks and green spaces development policy, but the London case remains a good example; this is because green infrastructure policies in London were not a manifesto pledge but rather have been continuously and consistently advanced regardless of party politics and thus realised as long-term planning.

  • 최근 전 세계는 급격한 기후변화와 도시화의 집중 등으로 인해 예상치 못한 수문학적인 문제, 특히 도시 내 홍수 피해 규모와 빈도가 매년 증가하고 있다. 기존의 도시 개발은 그레이 인프라(Gray Infrastructure)형을 중심으로 불투수 포장면의 증가를 가져왔다. 그 결과로 자연적 투수층이 감소하여 첨두유량 증가, 침투량 감소와 같은 도시물 순환의 문제점이 부각되기 시작했다. 이에 많은 국가들이 그린 인프라(Green Infrastructure)의 중요성과 필요성을 인지하고 그와 관련된 정책 마련에 나서고 있다. 그린 인프라는 모든 개발사업의 계획 이전에 고려되느냐 기타 기반 시설의 계획 후 입지를 결정하느냐에 따라 입지 선정 기준을 크게 두 가지로 구축할 수 있는데, 본 연구는 도시 내 물 순환을 관리하여 유출수를 지표로 침투시켜 도시의 회복력을 평가하는 것이기 때문에 후자에 해당된다. 자연과 분리되거나 별도로 적용하지 않으면서 기후변화에 대응할 수 있는 지속가능한 도시를 만들 수 있으며 소규모로도 물 순환을 가능하게 해 도시의 큰 구조적 변화 없이 적용 가능하다. 본 연구에서는 서울 신월지구에 선행 된 시험 관측 결과를 토대로 도시 내 그린 인프라의 설치에 따른 도시 회복력에 대한 정의를 내려보았다.

  • Community infrastructure contains national facilities that directly affect the quality of life of citizens. They need to be evenly supplied to every one of citizens. However, the services provided by infrastructure differ by region. In this paper, we propose a method to analyze the current status of the supply of community infrastructure consisting of accessibility and capacity. Accessibility can be evaluated by the time between residence blocks and facilities, which is an indicator of the convenience of citizens. Capacity is assessed by the area supplied for the local population, to assess whether facilities are being sufficiently supplied to the region. The method presented in this paper was applied on a case region to test the applicability. The analysis method of the supply status of community infrastructure in this study is considered to be used as a basic framework for regional supply plan of community infrastructure and urban planning.
