Following is a brief summary for each of the winners.
Ms. Grace Kanonge is a Master of Philosophy student at University of Zimbabwe Department of Soil Science & Agricultural Engineering (SSAE) in Harare, Zimbabwe. She is working towards completion of her thesis entitled “A Fertilizer Management Strategy for Enhanced Legume-Cereal Productivity under Smallholder Farming Systems of Zimbabwe” The study sought to enable resource constrained smallholder farmers to efficiently manage combinations of locally available organic nutrient resources and purchased mineral fertilizers [particularly (P)] to increase productivity and rotational benefits of N2-fixing grain legumes on staple maize. Under this management concept, targeted P fertilization of the legumes, to increase N inputs from the biological nitrogen fixation, was evaluated against a traditional fertilization option under which a subsequent legume is dependent on residual fertility. Ms. Kanonge is in the process of publishing results of her research in peer-reviewed journals, and hopes to develop her research capabilities further by pursuing a doctorate degree in soil fertility and plant nutrition.
Mr. Boaz S. Waswa is pursuing his Ph.D. at the Center for Development Research (ZEF) in Bonn, Germany. His dissertation is titled “Assessment of Land Degradation Patterns in Western Kenya: Implications for Restoration and Rehabilitation.” The study aims to assess long-term spatial and temporal patterns of land degradation using multi-scale satellite data sets. Detailed field observations and measurements along with a socio-economic survey will help understand the decision-making process for regional land management. The principles learned could be applied to derive a set of recommendations needed for sustainable land management in Kenya. Mr. Waswa aspires to be a technical advisor to government or other agencies working in the areas of food security and environmental conservation.
