Name: FANTONG Wilson Yetoh
Nationality: Cameroonian
Institution: Institute of Geological and Mining Research
Activities-Monitor and evaluate quantity of water resources (rain, surface and groundwater) in the 05
hydrological basins in Cameroon-Monitor and evaluate chemistry and quality of water resources (rain, surface andgroundwater) in the 05 hydrological basins in Cameroon- Coordinate scientific works (limnology) of Lake Monoun in the Western Region of
Cameroon. The lake exploded in 1984 killing 34 people and we do conduct regularmonitoring of the lake to mitigate recurrence of the 1984 saga.
-Coordinate applied research on the suitability of water resources for agriculture in the
Sahelian Northern Regions of Cameroon-Chair of the scientific and technical committee for Global Water Partnership in Cameroon- Evaluate the interaction between marine and continental waters along the 420 km longcoastline of Cameroon-Teach Integrated Water Resources Management, hydrology and hydrogeology at the
University of Buea in Cameroon-Establishment of technical coorperation between my home institution (IRGM) with JICA,
University of Toyama-Japan, University of Hiroshima-Japan, and BGR-Germany.

My PORTRAITSMeasuring In Situ parameters during sampling of community drinking water
sources
Activities
Inter University academic exchange agreement: Still to be establish between
University of Toyama and Institute of Geological and Mining Research
MEXT scholarship cooperation: Yes, I coorperate with University of Toyama
within the framework of the MEXT scholarship, by encouraging Cameroonian
student to seek admission in the University of Toyama. Actually, there is one
Cameroonian student pursing her PhD now at the University of Toyama, throughmy guidiance.
Accepting faculty members and students from University of Toyama:
Within the framework of a project “ SATREPS-NyMo” that ran from 2011 to 2016,
with follow-up activities that continued till February 2024, I received thefollowing Professors from the University of Toyama: Professor Akira Ueda andProfessor Minoru Kusakabe.

Co-authorship of scientific papers with Researchers in the University of
ToyamaI have co-authored eighteen (18) scientific articles with Researchers from the
University of Toyama. See them hereafter listed.
