Ken Giller is a professor of plant production systems in the Wageningen Centre for Agroecology and Systems Analysis (WaCASA) of Wageningen University. He leads a group of scientists who have profound experience in applying systems analysis to explore future scenarios for land use with a focus on food production. Dr. Giller’s research has focused on smallholder farming systems in sub-Sahara Africa, particularly problems of soil fertility and the role of nitrogen fixation in tropical legumes, with emphasis on the temporal and spatial dynamics of resources in crop–livestock farming systems and their interactions. He is the author of the standard text, Nitrogen Fixation in Tropical Cropping Systems, whose second edition was published in 2001. He leads a number of initiatives, such as N2Africa (Putting Nitrogen Fixation to Work for Smallholder Farmers in Africa), NUANCES (Nutrient Use in Animal and Cropping Systems: Efficiencies and Scales), and Competing Claims on Natural Resources. Dr. Giller joined Wageningen University as chair of plant production systems in 2001 after holding professorships at Wye College, University of London, and the University of Zimbabwe. He holds a PhD in ecology from Sheffield University.
