Built-in Disaster Mitigating Urban Management of Hillside Towns

冈田和他的研究合作者为这个项目提出了一个新的视角，即对山坡城镇的内置减灾城市管理。根据山坡城镇的地理、环境和社会经济特征，建立了山坡城镇分类。基于这一观点，为案例研究城市长崎和神户确定了原型山坡城镇并建立了模型。冈田和杉曼在长崎市的实地调查中进行了合作，并收集了随后进行分析所需的信息和数据。Hagihara和Okada共同努力建立分析模型，以得出对长崎市管理的政策影响，并适当地纳入减灾措施。具体地说，为协调发展利益和减灾利益进行了冲突分析；作为相关研究，Okada等人发展了“稳健性分析”方法，该方法被证明是处理模型参数识别中涉及的不确定性的强有力的分析工具。人们注意到，我们的新研究视角也适用于这一地震灾区。Sugiman对该地区进行了实地调查，特别侧重于社区和志愿活动的作用。利用“群体动态”的办法有助于确定社区和减灾志愿团体管理所涉政策问题。

A new perspective of built-in disaster mitigating urban management of hillside towns has been proposed by Okada and his research collaborators for this project. A taxonomy of hillside towns has been created with reference to their geographical, environmental and socio-economic characteristics. Based on this perspective, prototype hillside towns have been identified and modeled for the case study cities of Nagasaki and Kobe.Okada and Sugiman have collaborated in the field survey of Nagasaki City and collected information and data needed for the analysis that followed. Hagihara and Okada jointly worked to build analytical models to derive policy implications for the management of Nagasaki City with disaster mitigation duly built in. Specifically, a conflict analysis has been made to coordinate developmental interests with those of disaster mitigation.As a related study, the method of "robustness analysis" has been developed by Okada et al and it has been shown to be a powerful analytical tool to deal with uncertainties involved in identifying model parameters.Further research has been conducted to study the Hanshin Region which suffered from the Great Hanshin Earthquake. It has been noted that our new research perspective also applies to this earthquake-stricken region. Sugiman has carried out a field survey of the region, with a particular focus on the roles of communities and voluntary activities. An approach by use of "group dynamics" helped identify policy implications for the management of community and voluntary groups for disaster mitigation.
