Abstract
Toshio Koike received the Bachelor, Master, and Doctor of Engineering, in 1980, 1982, and 1985,
respectively, from the University of Tokyo, Japan. He was at the University of Tokyo, as a research associate
in 1985 and a lecturer from 1986 to 1987, and at the Nagaoka University of Technology, Japan as an
associate professor from 1988 to 1999 and a professor in 1999. In 1999, he joined the Department of Civil
Engineering, the University of Tokyo, where he held the position of Professor until 2017. He is also working as
Advisor to the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT). Since
October 2014, he has been appointed as Director, International Centre for Water Hazard and Risk
Management under the auspices of UNESCO (ICHARM), Public Works Research Institute (PWRI) in Tsukuba,
Ibaraki, Japan.
His research interest includes the water cycle and climate sciences and their applications to water resourcesmanagement, which can be classified into the following three components, establishment of satellite remotesensing, development of the data integration and information fusion system, and development of thehydrological down-scaling methods including satellite-based data assimilation. Aside from his scientificcontributions to water cycle and climate sciences and water resources management, he has been leading theinternational water cycle science projects and the inter-governmental science and technology cooperation.
He implemented the Coordinated Enhanced Observing Period (CEOP), which was an element of World
Climate Research Programme (WCRP) initiated by Global Energy and Water Cycle Experiment (GEWEX), as
Lead Scientist. He was Co-Chair of Coordinated Energy and Water Cycle Observations Project (CEOP) of
GEWEX from 2008 to 2010 and has been working as Co-Chair of WCRP Data Advisory Council (WDAC)
since 2012. To give some more breakthroughs in his global data integration activities, he has initiated the
project, Data Integration Analysis System (DIAS) supported by the Japanese government in 2006, and he has
been leading it domestically and internationally since then. With his much passion for solving the water
problems in the Asian region by utilizing the cutting-edge science and technologies, he has been leading the
Asian Water Cycle Initiative (AWCI) contributing to the Group on Earth Observations (GEO) since 2005 andthe similar water cycle initiative activities are now launched into the African continent (AfWCCI). He also
contributed to development of the “GEO Strategic Plan 2016-2025” as Co-Chair of the Implementation Plan
Working Group (IPWG). He is also chairing River Council of Japan and the Asia-Pacific Water Forum (APWF)
Steering Group on Water and Climate Change.
Some of the prominent awards he has won recently include the following: "Award for Contribution to the IPCCNOBEL Peace Prize" from WMO and UNEP" in 2008, "Einstein Lecturer Award" in 2009 from Chinese
Academy of Sciences, China, "Japan Water Award -International Contribution" in 2010, "Science Award"
from by the Japan Society of Hydrology and Water Resources in 2015.
