Extreme weather caused by global warming has caused an increase in the number and intensity of heavy rain disasters. Almost half the area of the Kofu Basin, Yamanashi Prefecture, Japan, is expected to be flooded by the largest expected rainfall in the basin. Approximately 310,000 people live in the inundation area, and the formulation of a wide-area evacuation plan in the event of a flood is an urgent issue. In the southern part of this area, where the estimated inundation depth is 5–10 m, a new station of the Linear Chuo Shinkansen Line, which will start operation in 2027, is planned, and urban development centered on the station is expected. In order to build a sustainable city that is resilient to floods in such a flood hazard area, the author established a study group on urban development consisting of knowledge brokers—professors at University of Yamanashi—and experts with the participation of local government observers. The group has proposed a future image of sustainable Kofu Basin under the initiative of knowledge brokers with the cooperation of experts. The group attempted to put into practice the concept of sustainable cities presented by the author. As a result, by the unusual town development activities of the study group, perspective drawings that provide the participants a common recognition of the city development were successfully created.

Pidie is one of the districts in Aceh Province that has been suffering from flooding. Frequent disasters, especially flooding associated with various causative factors, need mitigation efforts. An appropriate land use planning by considering the risk aspects especially in flood is an important step. Objectives of this study are to determine the factors influencing the flood hazard, to map the areal distribution vulnerable to flood, to analyze the relations of land use in the flood hazard area, and to analyze the relations between the planned spatial pattern and the flood hazard area. ,Multicriteria analysis was used to determine the factors influencing the flood hazard. Spatial analysis was used in mapping the class of flood hazard, the relations of land use in the flood hazard area, and the relations between the planned spatial pattern and the flood hazard area. The results show that the main factors influencing flood vulnerability are land use/cover (0.408), rainfall (0.266), and slope (0.184). Based on the classification of flood vulnerability, the area can be divided into more vulnerable (37.75 %), less vulnerable (30 %), and mildly vulnerable (22.76 %). The vulnerability classes of the land use/cover are: less vulnerable (99.99 %) and more vulnerable (97.57 %) dominated by forest cover; mildly vulnerable (51.07%) and vulnerable (92.65%) dominated by mixed farming; and very vulnerable (97%) dominated by settlement. The flood vulnerability of the planned spatial pattern can be classified as follows: 95.44 % of the conservation area is dominated by less vulnerable and more vulnerable, while 71.20 % of the cultivation area can be categorized into mildly vulnerable, vulnerable and very vulnerable.

The flood disaster has caused much harm to human life. Efforts to reduce the losses incurred by the policy directed the development of disaster-based residential areas based. The purpose of determining the direction of the policy of settlement development in the area of flood hazard in Limapuluh Kota District. To determine policy direction using AHP approach by involving 25 experts from related institutions. To determine the sustainability of development using the MDS approach. The result of policy analysis of the development of settlement area in the flood hazard area shows that there are three alternatives, namely a) disaster education; b) increased socialization in the flood hazard zone, and c) disaster-based space planning. In addition, the analysis of the sustainability of the development of residential areas shows that the institutional and legal dimensions are still low. Therefore, it is necessary to have the firmness and consistency of the government in spatial planning.

Regenerated hanoks, Korean-style vernacular houses in Bukchon (North Village) of Seoul, have been celebrated as the successful examples of a hybrid dwelling integrating modern facilities in a traditional house form. While the modernization project during the postwar era encouraged South Koreans to live in high rise apartments, hanoks became one of the alternative residential options as urban forest of concrete high rises were perceived to be aesthetically unappealing as well as ecologically unsustainable. Hopes are high that remodeled hanoks can ameliorate not only dreary urban landscape but over-competitive and harsh everyday life conditions. While preservation guidelines for regenerated hanoks provide residents with a possible stylistic model, it becomes questionable whether they are viable solutions given the proliferation of structures which seemingly adhere to the guidelines without considering local urban context. By pointing out the difference between the preservation guideline and its real life manifestations, this paper illustrates how imagined aspect of the vernacular architecture takes precedence over the experiential aspect. In this process of selective appropriation, various vernacular housing types are flattened into a standardized representation of upper class dwellings. This article concludes that it is possible to bring diversity by encouraging flexible interpretations of vernacular architecture and incorporation of residents' memories in the design process.

The development of strategies to adapt to and mitigate the potential adverse consequences of natural hazards requires support from risk assessment studies that quantify the impacts of hazardous events on our society. A comprehensive analysis of risk commonly evaluates the elements exposed to the hazard probabilistic scenarios and their vulnerabilities. However, while significant advances have been made in the assessment of direct losses, indirect impacts are less frequently examined. This work assesses the indirect consequences of two hydrologic hazards, i.e., pluvial and fluvial floods, in an urban context from a system perspective. It presents a methodology to estimate the services accessibility risk (SAR) that considers the accessibility of roads and the connection between providers and users of services in a city. The feasibility of the proposed approach is illustrated by an application to a pilot study in Monza city (northern Italy) considering pluvial and fluvial flood hazard with different return periods. The results in terms of the social and economic impacts are analyzed considering features of age, disability, and the different economic sectors.

New Jersey’s coastal zone has a long history of storm and flood hazard vulnerability, as documented by copious technical reports, historical maps and surveys, storm damage assessments and flood insurance claims. In the context of geologic time, this vulnerability can be attributed, in part, to increasing sea level rise resulting from melting of Pleistocene glaciers. In the context of human time, extensive development, redevelopment and urbanization of the New Jersey coast has contributed significantly to this vulnerability. At the same time, financial constraints at the state and federal level and increasing taxpayer liability for damage recovery costs will create challenges in long-term adaptation. A number of New Jersey academics have identified the magnitude of natural hazard vulnerabilities and the importance of mitigation to promote public safety, with James K. Mitchell of Rutgers University being one of the notable contributors to that effort. Current mitigation measures may be partially effective in protecting people and property in the short term. However, barriers to effective hazard area management and adaptation planning, including physical, financial, social, demographic and political constraints, need to be addressed. Understanding the scope and impact of these barriers is critical to developing the necessary long-term adaptation plans that will promote a safe and sustainable future for New Jersey.
