The Centre for Gender and Africa Studies (CGAS) and the UFS will host an Africa Day Webinar on the topic, Reflections on Africa amidst Covid-19, to be delivered by Prof. Sabelo J. Ndlovu-Gatsheni, renowned decolonial scholar. The title of his lecture is Revisiting the African idea of Africa during the moment of Covid-19 pandemic.

The crisis delivered by Coronavirus and Covid-19 invites Africans to rethink and even unthink the long-standing dependency on Europe and North America for help. What has dawned on Africa is the equally long-standing aspiration of self-reliance. What is emerging is a new African idea of Africa which takes responsibility for its own challenges. This new African idea of Africa challenges the Mudimbean idea of Africa embodied in the colonial library.

Thus this presentation reassesses how Africa has relied on its own historical experience, its own knowledge, and own people to confront Covid-19. What is of interest here is the proverbial wisdom of necessity being the source of invention. The presentation brings to the fore the decolonial turn as it gestures beyond crisis into post-Covid-19 world order. It ends with a call for decolonial love founded on new ethics of living together and new economies of care.

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.”
