Scientist within the Sustainable Intensification Program of CIMMYT based in Nairobi, Kenya. Leonard Rusinamhodzi holds a PhD in Production Ecology and Resource Conservation from Wageningen University and Research Center, The Netherlands. His work involves advanced analyses to study the effects of sustainable intensification on system productivity, soil quality, water and nutrient use efficiency across east and southern Africa. Leonard has extensive experience spanning more than a decade in participatory research in smallholder farming systems, with a deep understanding of the complex barriers to improved crop productivity. He has published extensively in the field of agronomy and targeting sustainable intensification options to the biophysical and socio-economic conditions of smallholder farmers. Leonard is particularly interested in learning and managing science that develops and uses tools that combine social, economic and bio-physical aspects of farmers to improve productivity and reduce hunger for smallholder farmers in Africa and beyond.
