  • Facing the global crisis of climate change, waterfront areas are experiencing a significant increase in property damages and casualties. In light of the climate change era, this paper aims to identify resilience strategies against rising sea levels and associated natural disasters. A comparison and analysis of resilience plans and strategies have been conducted for five waterfront cities. In conclusion, three key points are suggested. Firstly, establishing partnerships locally and globally is an emerging trend to effectively and collaboratively address climate change. Secondly, resilience is a fundamental concept in designing social, built, and cyber infrastructure, requiring attention from stakeholders. Lastly, designing a well-operating system is critical to respond effectively when external shocks or stress occurs.

  • Purpose: This study aims to suggest new strategy of planning water management and land use in response to abnormal weather which allow waterfront to be the cities through the experience of Netherlands resilient project. Method: A planning direction is developed based on Dutch national resilient policy and strategy as well as resilient theory of technical and social aspects, focusing on a new waterfront development that responds to abnormal weather. Results: The water control strategy, for flexibly responding to the sea level rise and flooding caused by the climate change through the experience of Dutch resilience, is as follows: 1)Customized prevention plan according to the local property 2)Creating spatial planning by considering disaster risk level and fragility 3)Establishing urban planning by considering the flood risk level. Conclusion: A new urban development method, particularly a resilience strategy based on the waterfront space where is most vulnerable to climate change, is required to cope with the abnormal climate beyond the conventional planning.

  • As the damage caused by the abnormal climate due to climate change is increasing, the interest in resilience is increasing as a countermeasure to this. In this study, the resilience of Suwon city was examined and the plan to improve the resilience were derived against climate impacts such as drought, heatwave, and heavy rain. Urban resilience is divided into social resilience (e.g. vulnerable groups, access to health services, and training of human resources), economic resilience (e.g. housing stability, employment stability, income equality, and economic diversity), urban infrastructure resilience (e.g.residential vulnerability, capacity to accommodate victims, and sewage systems), and ecological resilience (e.g. protection resources, sustainability, and risk exposure). The study evaluated the urban resilience according to the selected indicators in local level. In this study, the planning elements to increase the resilience in the urban dimension were derived and suggested the applicability. To be a resilient city, the concept and value of resilience should be included in urban policy and planning. It is critical to monitor and evaluate the process made by the actions in order to continuously adjust the plans.

  • Current cities encounter various types of water problems due to rapid urbanization and climate change. The increasing significance of urban water problems calls for the establishment of resilient alternatives to prevent and minimize social loss that results from these phenomena. As a background research for establishing resilient infrastructures for the mitigation of urban water problems, we evaluated the robustness of structural alternatives for urban flood as a representative case. Combining the robustness index (RI) and the cost index (CI), we suggested the robustness-cost index (RCI) as an indicator of the robustness of structural alternatives, and applied the index to assess the existing infrastructures and structural alternatives (i.e., sewer network expansion, additional storage tank construction, and green roof construction) at a site prone to floods located around Gangnam-station, Seoul, Korea. At a rainfall intensity frequency range of 2 to 20 years, the usage of a storage tank and a green roof showed relatively high RCI value, with a variation of an alternative showing greater RCI between the two depending on the size of design rainfall. For a rainfall intensity frequency of 30 years, installing a storage tank with some green roofing was the most resilient alternative based on the RCI value. We proposed strategies for establishing resilient infrastructures for the mitigation of urban floods by evaluating the robustness of existing infrastructures and selecting optimal structural alternatives with the consideration of scales of design disaster.

  • This study is a case study that applied 'UNDRR's Urban Disaster Resilience Scorecard', an evaluation tool necessary for Incheon Metropolitan City to be certified as an international safe city. I would like to present an example that the results derived from this scorecard contributed to the Incheon Metropolitan City Disaster Reduction Plan. Of course, the Disaster Resilience Scorecard can't provide a way to improve the resilience of every disaster facing the city. However, it is to find the weakness of the resilience that the city faces, and to propose a solution to reduce the city's disaster risk. This is to help practitioners to recognize the disaster risks that Incheon Metropolitan City faces. In addition, the solution recommended by UNDRR was suggested to provide resilience in areas vulnerable to disasters. It was confirmed that this process can contribute to improving the disaster resilience of Incheon Metropolitan City. UNDRR has been spreading 'Climate Change, Disaster-resistant City Creation Campaign', aka MCR (Making Cities Resilient) Campaign, to cities all over the world since 2010 to reduce global cities' disasters. By applying the disaster relief guidelines adopted by UNDRR, governments, local governments, and neighboring cities are encouraged to collaborate. As a result of this study, Incheon Metropolitan city's UN Urban Resilience Scorecard was evaluated as a strong resilience field by obtaining scores of 4 or more (4.3~5.0) in 5 of 10 essentials; 1. Prepare organization for disaster resilience and prepare for implementation, 4. Strong resilience Urban development and design pursuit, 5. Preservation of natural cushions to enhance the protection provided by natural ecosystems, 9. Ensure effective disaster preparedness and response, 10. Rapid restoration and better reconstruction. On the other hand, in the other five fields, scores of less than 4 (3.20~3.85) were obtained and evaluated as weak resilience field; 2. Analyze, understand and utilize current and future risk scenarios, 3. Strengthen financial capacity for resilience, 6. Strengthen institutional capacity for resilience, 7. Understanding and strengthening social competence for resilience, 8. Strengthen resilience of infrastructure. In addition, through this study, the risk factors faced by Incheon Metropolitan City could be identified by priority, resilience improvement measures to minimize disaster risks, urban safety-based urban development plans, available disaster reduction resources, and integrated disasters. Measures were prepared.

  • Landscapes and gardens have emerged as an important medium of practice in contemporary cities. Among them, this paper examines the city through the frame of gardens. This is because gardens are being reconceptualized as a medium of activity for urban residents and have become an important subject of action in urban regeneration and the creation of urban villages. From this perspective, this paper examines and proposes an "integrated garden city theory" as a landscape theory suitable for the contemporary era by focusing on the urban structure and the behavior of urban residents through the medium of gardens, as well as the process and results. This is both a process and a result of looking back at the evolution of landscape for over a century and rethinking the identity of landscape. We first examined garden city theory, noting that Ebenezer Howard and Frederick Law Olmsted's positions on the relationship between gardens and cities were not so different, and that "working and responsive landscapes" were fundamental to cities and the beginning of landscape theory. We also examine how their ideals have not been fully realized in cities over the past century, but the prototype of gardens based on traditional garden culture is now being formed in East Asian cities, and the evolution of landscape theory in response. The conclusion is that a new version of the garden concept should be reestablished as a living infrastructure in our cities, and a new garden city theory is needed to make it work. To this end, each chapter examines three arguments, as follows First, the values of gardens and East Asian garden cultures in contemporary cities are shaped by the themes of community and integrity. Second, Korean communality, represented by apartments, is expressed through gardening and requires the reconciliation of city and life and the role of landscape architecture as a specialized field to support it. Third, we examine and consider an integrated garden city theory as a theory of practice in which city-based, everyday life, and garden mediums, i.e., city, life, and garden, are organic, based on an oriental view of nature. As a result, it is confirmed that contemporary gardens and cities are looking for important elements and values that still need to be rediscovered in East Asian landscape and garden cultures. Although the proposal of an integrated garden city theory cannot guarantee the continuation of landscaping, it can be an opportunity for all fields related to cities, not just landscaping, to collaborate and consider garden cities. Through this, it is hoped that "the concept of garden and city suitable for metropolitan or dense cities, ways to spread and support garden culture based on community, evolution of landscape theory/design theory suitable for lifestyle and terrain conditions, search for sustainable/resilient garden city theory that can respond to climate change, and establishing a new role for landscape in the 21st century" will be seriously considered.

  • 최근 기후변화로 인한 수문기상학적인 극한 사상들은 점점 대형화되고 있고, 그 발생빈도 또한 잦아지고 있다. 인구의 증가와 급격한 도시화, 자산 가치의 증가 등으로 물과 관련된 재해로 인한 피해는 점점 더 규모가 커지고 있다. 홍수와 가뭄, 허리케인, 쓰나미와 같이 물과 관련된 재해는 그 영향을 받는 사람들의 수로 본다면 지구상의 재해 중 90%를 차지하고 있을 만큼 그 규모가 크다 할 수 있으며, 전세계적으로 물관련 재해로 인한 재산상의 피해를 약 1,000억 달러 규모로 추산하고 있는데, 2030년에는 그 현재의 두 배가 될 것으로 예측하고 있다. 이와 같은 재해로 인한 피해는 개도국이나 최빈국뿐만 아니라 관련 인프라가 잘 구축되어 있는 선진국 또한 예외는 아니다. 2015년 9월 UN 세계지속가능 정상 회의에서 각국의 수반들 또한 17개의 "지속가능개발목표(Sustainable Development Goals; SDGs)"를 채택함으로서 post-2015 아젠다가 세계를 지속가능하고 균형 있게 바꾸어 나가기 위해서 취해야 하는 가장 시급하고 필요한 과감한 혁신적인 조치임을 인식하였다. 재해경감과 지속가능개발은 2005년 채택된 "효고프레임웍(Hyogo Framework for Action) 2005-2015"에서 도 중요하게 다루어 졌다. 2015년 3월 제3차 세계재해경감대회에서 채택된 "센다이 프레임웍(Sendai Framework for Disaster Risk Reduction) 2015-2030"은 Post-2015 개발의제의 첫 번째 합의 결의안이라 할 수 있으며, 인명피해의 실질적인 감소와 재해에 의한 영향으로 피해 보는 사람들의 수를 줄이고, 경제적 손실과 대형 인프라 피해의 경감을 주요 타겟으로 하고 있다. 이와 같은 리질리언스의 중요성은 SDGs의 Goal 11인 "안전하고 지속가능한 도시와 정주지 조성(Make cities and human settlements inclusive, safe, resilient and sustainable)"에서 강조되고 있을 뿐만 아니라 다양한 골에서 재해로 부터의 리질리언스 확보에 대한 필요성을 강조하고 있다. 재해 위험을 경감시키기 위해서 국제적으로, 지역적으로 또는 국경을 넘어서는 협력 관계의 구축이 중앙정부나 지방정부를 비롯한 국가적으로 절대적으로 필요한 노력이라 할 수 있다. 특히나, Post-2015 개발 아젠다에 대한 기후변화와 재해경감을 위한 금융지원을 포함한 최빈국, 개도국, 군소 도서국가들과 중견국 선진국들의 양자간이나 다자간 협력 채널을 통한 역량 강화가 필요하다.

  • In this study, the weather conditions corresponding to the increase in the environmental concentration of fine dust (PM10) and ultrafine dust (PM2.5) from 2001 to 2019 in Jeju and Seogwipo cities were analyzed. The increase in the levels of PM10 and PM2.5 was observed in the order: spring > winter > autumn > summer. In both cities, PM10 and PM2.5 levels increased more frequently during the day in spring and summer and at night in autumn and winter, with PM2.5 showing a greater increase in concentration than PM10. The air temperature and wind speed corresponding with increased levels of PM10 were higher than their respective seasonal averages in spring and winter, but lower in summer and autumn. Relative humidity was lower than the seasonal average during all seasons. The air temperature variation corresponding with increased levels of PM2.5 showed the same seasonal trend as that observed for PM10. The relative humidity was higher than the respective seasonal averages in spring and summer, and lower in winter. The wind speed was lower than the seasonal average in both the cities. When the PM10 and PM2.5 levels increased, the wind direction was from the north and the west during the day and varied according to the season at night. The rate of the increase in the PM10 concentration was the highest in both cities at the wind speed of 1.6 - 3.4 ms-1 during the day and night except during night in the summer. The highest concentration of PM2.5 was observed with the wind speed range of 1.6 - 3.4 ms-1 in Jeju, and 0.3 - 1.6 ms-1 in Seogwipo. The results of this study applied to urban and landscape planning will aid in the formulation of strategies to reduce the adverse effects of fine particular matter.
