Prof Oliver Mutanga, a University of the Free State (UFS) alumnus with a PhD in Development Studies and an experienced researcher focused on matters pertaining to disability, education, equality, and health issues, recently took up the position of Assistant Professor in the Graduate School of Education at the Nazarbayev University in Astana, Kazakhstan.

Prof Melanie Walker, Director of the SARChI Chair in Higher Education and HumanDevelopment (HEHD) at the UFS, invited Prof Mutanga to discuss his own research via an open webinar and to engage with members of her research group.

Prof Walker explained that she was delighted to host Dr Mutanga at the university, given his profile as an outstanding and internationally mobile early career researcher, from whom others in her group could learn. “Further, I very much wanted Dr Mutanga to speak about his own research, given its overall academic excellence, quality, and impact. Going forward, I am looking forward to developing this link with Dr Mutanga and his colleagues abroad around critical diversity studies,” she states.

Profs Walker and Mutanga have collaborated in the past to write articles for academic journals arising from his doctoral research. Examples include, ‘Towards a disability-inclusive higher education policy through the capabilities approach’ (published in the Journal of Human Development and Capabilities) as well as ‘Exploration of the academic lives of students with disabilities at South African universities: Lecturers’ perspectives’ (published in the African Journal of Disability).

Prior to joining Nazarbayev University, Prof Mutanga gained valuable research and development experience in various countries, including Zimbabwe, Botswana, South Africa, Norway, and the United Kingdom.

He has also received several accolades for his work, including the prestigious Marie Sklodowska Curie Postdoctoral Fellowship at the University of Oslo, Norway, and the Global Challenges Research Fellowship at University College London's Institute of Education.

A unique outlook on disability

In 2013, Prof Mutanga was part of the first cohort of PhD students under the SARChI Chair in Higher Education and Human Development. Recently, during his three-day visit to the UFS, he addressed the HEHD research group and an international academic audience during a hybrid seminar on the perceptions and experiences of disability within the Tembo Mvura communities of Northern Zimbabwe.

In his research for this paper, Prof Mutanga uses storytelling and in-depth interviews to offer a distinctive, community-based, and Southern interpretation of disability. By applying the capabilities approach and the ubuntu philosophy, his study presents a contrast to Western perceptions of disability that often emphasise individual limitations and differences based on physical and mental characteristics, which have the potential to both result in isolation and to understanding people as autonomous but isolated beings.

Within the Tembo Mvura communities, he discovered that disability is viewed through a lens of interconnectedness between individuals, their environment, and the spiritual world: “They recognise the inherent worth and dignity of all individuals, irrespective of their impairments,” found Prof Mutanga. Indeed, impairment of full personhood is understood as lacking in any of the three dimensions outlined above.

Thus, Prof Mutanga explored the complex interaction of identity, access to land, laws, and language, as well as labelling, highlighting how these factors shape perceptions and experiences of disability within these communities.

He is of the view that these findings will have implications for North-dominated disability discourse and for policy, practice, and research within indigenous contexts, such as the Tembo Mvura, where disability is uniquely perceived and experienced.

In addition to the hybrid seminar, Prof Mutanga led valuable sessions with the HEHD Research Group, where the PhD and postdoctoral fellows had the opportunity to workshop and refine various aspects of their current research papers and to engage in discussions around building their academic careers.

UFS PhD student receives more than R5,8 million to take agricultural research to African farmers

Bright Peprah, a Plant Breeding PhD student from Ghana in the Department of Plant Sciences at the University of the Free State received an award from the competitive Program for Emerging Agricultural Research Leaders (PEARL) of the Bill and Melinda Gates Foundation (BMGF) for one of his projects.

From the more than 750 proposals for funding that were received from African researchers, only 19 received funding from PEARL. PEARL is an agricultural initiative by the BMGF to take agricultural research products to African farmers. It also aims at involving the youth and women in agriculture.

Peprah’s proposal to introgress beta carotene into farmer-preferred cassava landraces was part of the final 19 proposals funded. The project is being led by the Council for Scientific and Industrial Research (CSIR)Crops Research Institute (CRI), and has the International Institute of Tropical Agriculture (IITA) and the International Centre for Tropical Agriculture (CIAT) as international partners with Peprah as the principal investigator.

He received $473 000 (R5,8 million) for his project on the improvement of beta-carotene content in cassava.

Peprah decided on this project because the populations of underdeveloped and developing countries, such as Ghana, commonly suffer undernourishment and/or hidden hunger, predisposing them to diseases from micronutrients deficiencies. “Vitamin A deficiency constitutes an endemic public health problem which affects women and children largely,” he says.

“In Africa, cassava is widely consumed by the populace. Unfortunately, in these areas, malnutrition is endemic to a significant extent, partly due to the low micronutrients in this tuberous root crop, which is a major component of most household diets. It is for this reason that the development of nutrient- dense cassava cultivars needs much attention to eliminate the ramifications of malnutrition among the poor in an inexpensive and more sustainable way.

“To date we have selected top eight genotypes from germplasm collected from the International Institute of Tropical Agriculture (IITA) which are high in carotenoids and also poundable, a key trait to Ghanaian farmers. These eight genotypes have been planted at different locations in Ghana, and being evaluated by different stakeholders (consumers, researchers, producers, commercial farmers, processors, etc.). If found suitable, the genotypes will be released to farmers, which we hope will solve some of the micronutrient problems in Ghana.

“My projects seek to develop new cassava varieties that will have both high dry matter and beta carotene which has been reported to be negatively correlated (as one increase, the other decreases). The breeding method will be crossing varieties that are high in beta carotene with those with high dry matter, and checking the performance of the seedlings later. Developing such new varieties (yellow flesh cassava) will increase their adoption rate by Ghanaian farmers,” he said.

Prof Maryke Labuschagne, Professor in Plant Breeding in the Department Plant Sciences and Peprah’s study leader, said: “This project has the potential to alleviate vitamin A deficiency in the West African region, where this deficiency is rampant, causing blindness in many people, especially children."
