Personal Summary
Akoachere Richard Ayuk II is a Lecturer of Hydrogeology (1990- till date) with over twenty-six years of hydrogeology field experience. He has particular interest within African growing cities in Potable Water Access and Groundwater Characterization. He has pioneered projects across the Central and South African regions in this domain. With a great track record in post graduate research supervision and a good blend of research with impactful community based solutions, he has published widely on Hydrogeology, with over 14 peer-reviewed papers and two authored book chapter in the field.
His current research/consultancy is in; Rural Water Supply to Communities in Distress (RWSCD), Integrated Water resources Management (IWRM), Aquifer Characterization (AC), Fractured Rock Characterization (FRC) Environmental Impact Assessment (EIA). In Integrated water resources management (IWRM), His current research in this direction aims at giving new insights into practical solutions for tackling the problem of efficient and integrated management of water as a resource, especially in the water scarce and technically challenged environments in developing countries. Aquifer Characterization (AC) involves the complete determination of aquifer properties such as transmissivity, permeability, storage capacities, recharge, parameters that will enable a proper management of water as a resource since no one can manage what they don’t know. Fractured rock aquifer characterization (FRC). Cameroon is covered by over 80% of igneous and metamorphic rocks. Groundwater in these areas occurs mostly in fractured rock aquifers. A detailed studies of these aquifers is a prerequisite to the understanding of the hydro geology of Cameroun. He is committed to developing innovative and interdisciplinary action experimental research styles; invented two (02) new equipment in Hydraulics and Tracer testing and also invented five (05) new methods of carrying out field tests in Hydrogeology. He has been the Principal Investigator (P.I) for the “The Bulk Flow Project on the Karoo Aquifer South Africa (2006-2010); WRC/UFS Bloemfontein and has worked with external organizations, including the UNESCO-IHP (IRBM-Nigeria) and national government agencies. Since 2010 he has been a “Guest Professor” at Kumamoto University, Japan leading research and lecturing on African Hydrogeology. Over the past Twenty-six years he has lived and worked in Nigeria, Congo, South Africa, Japan and Cameroon speaking fluent English, French, Spanish.
