Other Research Themes

In cooperation with other research departments and divisions, we are also working on research topics such as, the role of urban (land use) planning to prepare for the increasing flood risk due to future climate change, and the planning process of the restoration plans from the Tsunami damage due to the Great East Japan Earthquake.

Study of Methods to Reduce Risks of Flood Damage Integrated with Urban Planning under Climate Change

As we face the risk of increased intensity and frequency of water-related disasters caused by climate change, it is expected not only to steadily promote infrastructure development but also to implement disaster reduction measures integrated with urban policy (example: responses in the Social Infrastructure Development Council, "Ways to adapt to climate change in the field of water-related disasters - To share the information of disaster risks and sense of crisis to build asociety to reduce disasters -" August 2015). Therefore, the NILIM Climate Change Adaptation Research Group in which Urban Planning Division participates, are carrying out studies, 1) to integrate urban overland flooding and river flooding risk evaluations, 2) to develop formulatation of low risk society taking into account the expected timeline of urban population reduction and aging, climate change progress, and time required until countermeasures are effective, and 3) to develop concrete procedures reflecting needs of inhabitants and firms.

Restoration Plans of the Tsunami Affected Cities and Tsunami-disaster Mitigation City Planning

The Great East Japan Earthquake of March 2011, was a cause of massive destruction by vast tsunami disaster beyond the scope of position at the time. Restoration planning of the affected cities had to deal with many issues, such as the necessity of selecting areas for reconstruction of communities, development of new preventive measures against tsunamis, development of plans for the utilization of land in coastal regions devastated by the tsunami, and provision of accommodation for tsunami victims, among other things. These and other issues have been intricately intertwined with one another, thereby making the current reconstruction project unprecedentedly large-scale and complex in the history of post-disaster reconstruction programs. We have investigated the process for the development of the reconstruction plan based on case studies.
Additionally, recent movements after the Earthquake towards tsunami-disaster mitigation city planning are summarized.
