Clarification of the relationship between storm surge damages and land use change accompanied by artificial terrain change in the affected areas of Typhoon 30 in the Philippines

Research grant

Project Description

Typhoon 30 occured on November 4 2013, causing serious damage to Tacloban, the central city of Leyte Island, Philippines. Tacloban is situated on the Eastern coast of Leyte Island and has a population of around 200,000 on the coastal plain. In this research, the relationship between urbanization of unplanned embankments and damage distribution intensity is verified by geographical information analysis. For mid-sized cities in developing countries, which lack geographical and statistical information, we established a process model for maintenance, analysis and mapping of high cost performance spatial information.

Graduated from the University of Tokyo School of Science in 2001 and entered the University of Tokyo Graduate School, Landscape Ecology and Planning Lab to begin research on Asian low wetland city development and flooding, conducting field research in Japan, Thailand and the Philippines. In 2005, withdrew from the doctoral course and became a special assistant professor at the University of Tokyo continuing to investigate the land environment towards a recylcing-oriented society in cities within Asia. In 2007, after compiling research results, received a doctoral degree in Agriculture. In 2009, transferred to Wakayama University and began research on rural metropolitan areas, which was connected to the research for this application.
