Senior Researcher | International Water Management Institute | Ghana
Dr. Noah Adamtey is a distinguished Agronomist and Environmental Scientist, currently serving as Senior Researcher in Resource Recovery and Agri-food Systems at the International Water Management Institute (IWMI), Ghana. He earned his BSc in Agricultural Science and MPhil in Environmental Science from the University of Ghana, followed by a PhD in Environmental Science from the University of Ghana in collaboration with IWMI and Eawag-Sandec, Switzerland, and later pursued a Habilitation at the University of Giessen, Germany, focusing on resource recovery and use efficiency in farming systems. With over two decades of expertise, Dr. Adamtey’s research spans agroecology, bio-circular economy, soil fertility, nutrient cycling, sustainable water use, and climate-resilient agricultural systems. He has led and collaborated on several international projects, including long-term farming systems comparison trials across Africa, Asia, and Latin America, significantly advancing knowledge on organic versus conventional agriculture. His extensive publication record includes impactful articles in Applied Soil Ecology, Frontiers in Sustainable Food Systems, and Global Environmental Change, as well as contributions to book chapters, training manuals, and technical guides. Dr. Adamtey’s research has been recognized with prestigious awards such as the 2025 IWMI Board of Governors Award, the 2021 Louis Malassis International Scientific Award for Agroecology, and the 2019 Swiss Forum for International Agricultural Research Award. Beyond research, he contributes to academia as a lecturer at the University of Giessen and University of Hohenheim, Germany, and has been instrumental in curriculum development for agricultural institutions in Africa. He is also an active reviewer for leading journals, including Nutrient Cycling in Agroecosystems, Agronomy Journal, and Sustainability. Through his scientific leadership, teaching, and international collaborations, Dr. Adamtey continues to influence sustainable agriculture, environmental stewardship, and food security worldwide
