International Strategy
東北大学災害科学国際研究所／
Ten years have passed since the Sendai Framework for Disaster Risk Reduction (SFDRR) was adopted by the United Nations Member States as one of the three major global agendas in 2015, the world has been facing more diverse and complex threats such as infectious diseases, conflicts, and disparities including poverty. However, the SFDRR's "pre-disaster investment in DRR" and "Build Back Better", which are the fundamental basis of Japan's development philosophy, are also imperative for not only DRR but also Sustainable Development Goals (SDGs) and climate change countermeasures, and there is a growing need to further strengthen its practice.
Tohoku University has been actively applying knowledge gained from disaster science to the actual betterment of our society including the regional recovery from the Great East Japan Earthquake. At our Green Goals Initiative, we are collaborating externally with other universities and relevant organizations in and out of Japan, and also internally with the International Research Institute of Disaster Science (IRIDeS) and other departments of Tohoku University to formulate international DRR strategies and practices. To this end, we will promote sharing and co-creating knowledge and information archives that will have substantial impacts on international DRR policy implementation and decision making, and global transdisciplinary DRR practitioner education. We will continue to use and enhance the circle/platform among like-minded DRR needing countries and entities such as the World BOSAI Forum where various people from industry, government, and academia can participate. By interconnecting those various actors, we will concretely contribute to the global DRR including the SFDRR mid-term review and the discussion towards the next framework.
国連の場で三大アジェンダの一つとして仙台防災枠組（SFDRR）が採択されてから10年が経過し、感染症や紛争の脅威は高まり、貧困等の格差拡大など、世界はさらに多様で複雑な課題に直面しています。しかし、仙台防災枠組の「事前防災投資」や「よりよい復興（Build Back Better）」といった、日本の開発理念にも通底する考え方は、防災だけでなく持続可能な開発（SDGs）や気候変動対策（パリ協定）の観点からもさらに重要になっており、より一層実践強化する必要が高まっています。
本学では，東日本大震災での支援や災害科学による知見を活かした連携活動を実施しており，グリーン未来創造機構では、災害科学国際研究所はじめ学内外の関連部局とも連携し、国際防災戦略の策定と実践を先導していきます．そのため，国際的な政策形成にインパクトを与える研究・実践成果の発信とグローバルな人材育成，実践的防災学を推進し、世界BOSAIフォーラムなど産官学の多様な関係者が参加出来るプラットホームを継続し，関連のプロジェクトを実施していきます．SFDRR中間評価や次期戦略の議論にも具体的に貢献し、防災知見や情報（アーカイブ）も積極的に発信していきます。

Research priority is “development and disaster risk reduction (DRR)”:
how DRR should be addressed within broader development challenges, rather than “DRR for the sake of DRR.”
「防災のための防災」ではなく、総合的な開発課題の中で災害リスク削減にどう取り組むべきかという「開発と防災」を最重要研究テーマとしています。

Water is the most abundant substance on the earth, the principal constituent of all living things, and a major force constantly shaping the surface of the earth. It is also a key factor in air-conditioning the earth for human existence and in influencing the progress of civilization. Changes in the distribution, circulation, or temperature of the earth’s waters can have far-reaching effects; the ice ages, for instance, were a manifestation of such effects. Changes may be caused by human activities, in particular, since the latter half of the 20th century. People cultivate the soil, irrigate crops, fertilize the land, clear forests, pump groundwater, build dams, dump wastes into rivers and lakes, and do many other constructive or destructive things that affect the circulation and quality of water in nature. Besides, an expanding population and a rapidly growing economy especially in Asia and Africa are hindering sustainability on the globe.
Our studies and challenges have been focused on solving the world water issuers by understanding water circulation, along with the following subjects: (1) Impact assessment on the hydrological change under the changing climate and the land use change at a global and local scale; (2) Mechanism of slope failure and wood debris by torrential rains; (3) Socio-hydrology: trade-offs between urban flood resilience and urbanisation; (4) Numerical study on water pollution in the inundation areas; (5) Long-term heat, vapour and carbon dioxide fluxes observation for an impact assessment on the interaction between land and atmosphere.
Furthermore, the following inter-/trans-disciplinary research has been focused on achieving local sustainability: (6) Understanding requirements for sustainability of community-based programs; (7) Value-based co-creation of technology and lifestyle for a society based on a virtuous materials cycle.

Climate change is intensifying hydro-meteorological extremes such as droughts, floods, and heatwaves, creating complex challenges for disaster risk reduction and sustainable development. My research focuses on understanding these evolving hazards and their interactions with human systems, particularly in vulnerable and rapidly developing regions.
In particular, I have been working on disaster risk assessments under a changing climate, with a primary focus on agricultural drought, as well as flood and heatwave hazards. My approach combines observed data with satellite-based and remote sensing datasets to enable high-resolution spatial and temporal analyses. This integration allows for assessments at the community level, where the impacts of climate extremes are most acutely felt, and where adaptation measures must be effectively targeted.
By integrating hazard characterization, exposure mapping, and vulnerability analysis, my work aims to identify risk hotspots and provide scientific evidence to support adaptation and disaster risk reduction strategies. Through this research, I seek to contribute to the development of methodologies and insights that can bridge the gap between large-scale climate information and local-scale decision-making.
