Research Interests

Water issues and disaster risk reduction are closely linked with most SDGs including SDG6 and SDG11. Natural disasters have occurred all over the world, and the economic damage has reached 3.5 trillion dollars (about 400 trillion yen) and the death toll has reached 2.3 million in the past 30 years. The damage continues to increase further due to population growth, urbanization, and climate change. The international organizations such as UNESCO, the World Bank, the Asian Development Bank, and JICA are addressing to reduce this damage, especially in developing countries, because disaster risk reduction is a foundation of their social and economic development. Japan has recently launched a new initiative,‘River Basin Disaster Resilience and Sustainability by All.’

Under these contexts, we are leading the research and development on the following themes using cutting-edge technologies including AI and advanced analysis models in collaboration with international organizations, governmental agencies, private sectors, other universities, and research institutes:

  • Development of risk assessment methods supporting ‘River Basin Disaster Resilience and Sustainability by All.’
  • Development of green infrastructure technologies for disaster resilience and sustainability.
  • Policy analysis and technological development on integrated water resources management, integrated flood risk management, and disaster risk management from the natural, social, and economic aspects.
