Biography

Abdulai Salifu is a Civil and Environmental Engineer, and obtained his BSc. degree (Civil Engineering) from the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana. He obtained his Post-Graduate diploma degree (passed with distinction) in Community Water Supply and Sanitation, from Loughborough University of Technology (LUT), England (U.K) and his MSc. degree in Environmental Engineering from the University of Newcastle upon Tyne, England (U.K). He worked for several years in the water sector in Ghana as a Water and Sanitation Engineer, where he worked in multi-disciplinary team professionals comprising of; Hydrogeologist, Sociologists, Health and Hygiene Education Specialist, IT Specialist and Planners, involved mostly in the provision of water supply and sanitation facilities as well as health/hygiene education to rural communities and small urban towns. He was involved in the planning and implementation of several water and sanitation projects in the Northern region of Ghana, financed by several External Support Agencies (ESAs), including the World Bank, European Union (EU), Agence Francais de Developpment (AFD), UNICEF, Japanese International Corporation Agency (JICA) and the Canadian Development Agency (CIDA).
