Citrus research in southern Africa, largely funded by a levy on export cartons, is divided into three portfolios.
Within each focused portfolio are several programmes on particular problem areas identified by the citrus industry. A Programme Coordinator oversees the research conducted within each programme and this may be conducted at various institutions. Programme Coordinators can also belong to different institutions. Within Citrus Research International (Pty) Ltd, Dr. Tim Grout manages the Research Division and serves as deputy to the Chief Executive Officer, Dr. Vaughan Hattingh who is based at the University of Stellenbosch.
