The late Prof Jaap Durand.
The management of the University of the Free State (UFS) is saddened to learn of the passing of Prof Jaap Durand, revered theological academic and author. Prof Durand obtained his master’s degree from the UFS and received an honorary doctorate in Philosophy from the UFS in 2004.
Prof Durand has had a colourful career as academic, writer, and struggle activist: from Professor of Systematic Theology and Dean of the Faculty of Theology at the University of the Western Cape to Deputy Vice-Chancellor of the same university. He also served as the ombudsman of Stellenbosch University from 2002 to 2003.
During his life, Prof Durand was a unifier and a critical voice, speaking out against injustice. He has also authored several books, including Dit is amper dag; Evolusie, wetenskap en geloof, and Protesstem.
The UFS joins the higher education community in mourning and is deeply saddened by the loss of such a great theologian and academic. We wish to convey our deepest condolences to Prof Durand’s family, friends, and loved ones during this time.
Researcher works on finding practical solutions to plant diseases for farmers

Plant disease epidemics have wreaked havoc for many centuries. Notable examples are the devastating Great Famine in Ireland and the Witches of Salem.
Plant diseases form, due to a reaction to suitable environments, when a susceptible host and viable disease causal organism are present. If the interactions between these three factors are monitored over space and time the outcome has the ability to form a “simplification of reality”. This is more formally known as a plant disease model. Lisa Ann Rothman, a researcher in the Department of Plant Sciences at the University of the Free State (UFS) participated in the Three Minute Thesis competition in which she presented on Using mathematical models to predict plant disease.
Forecast models provide promise fighting plant diseases
The aim of Lisa’s study is to identify weather and other driving variables that interact with critical host growth stages and pathogens to favour disease incidence and severity, for future development of risk forecasting models. Lisa used the disease, sorghum grain mold, caused by colonisation of Fusarium graminearum, and concomitant mycotoxin production to illustrate the modelling process.
She said: “Internationally, forecasting models for many plant diseases exist and are applied commercially for important agricultural crops. The application of these models in a South African context has been limited, but provides promise for effective disease intervention technologies.
Contributing to the betterment of society
“My BSc Agric (Plant Pathology) undergraduate degree was completed in combination with Agrometeorology, agricultural weather science. I knew that I wanted to combine my love for weather science with my primary interest, Plant Pathology.
“My research is built on the statement of Lord Kelvin: ‘To measure is to know and if you cannot measure it, you cannot improve it’. Measuring the changes in plant disease epidemics allows for these models to be developed and ultimately provide practical solutions for our farmers. Plant disease prediction models have the potential ability to reduce the risk for famers, allowing the timing of fungicide applications to be optimised, thus protecting their yields and ultimately their livelihoods. I am continuing my studies in agriculture in the hope of contributing to the betterment of society.”
