Senior Research Fellow


Dr. Benedicta Yayra Fosu-Mensah is an Ecology and Natural Resources Management scientist technically competent in applying the latest research methods and tools in modelling environmental issues, food crops production and environmental quality analysis (pollution). She has 10 years’ experience in research, teaching, workshop facilitation, student supervision and mentoring. Dr. Fosu-Mensah authored several peer-reviewed journal publications and co-authored a number of book chapters. Her research interest areas are climate change impact assessment and adaptation, environmental quality assessment (environmental pollution), site specific nutrient management, Land-use / land-cover change, and sanitation. She has worked on several community based and regional research projects, some with local and International Institutions.
