Prof Sue Walker is an Agrometeorology Specialist Researcher at the Agricultural Research Council, Pretoria, and Professor Emeritus in Agrometeorology at the University of the Free State,  Bloemfontein, South Africa. She supervised 21 Ph.D. students and published 113 peer-reviewed scientific articles. Her Ph.D. in Plant Physiology on sorghum water stress is from the University of California Davis, USA, following her studies at the University of KwaZulu Natal. Her research on under-utilized crops, using both field trials and crop modeling, continued at Crops for the Future on the University of Nottingham - Malaysia Campus leading the development of a CropBase information system for under-utilized crops. She develops climate services translating scientific results into useful operational messages, in Southern and East Africa as well as South East Asia. For many years, she worked together with farming communities using participatory methods to identify limiting factors in farming systems and co-develop interventions to address drought conditions and promote sustainable productivity. She applies evidence-based science to agricultural concerns using crop-climate modeling to develop and apply adaptation strategies addressing climate variability, and Agromet extension services for farmers, in semi-arid conditions using modern technologies. She is Project Leader for a Water-Energy-Food Nexus catchment-level project funded by the South African Water Research Commission.
