Since joining the UFS in 2008, Dr Grey Magaiza has worked extensively on approaches that can foster the socio-economic transformation of societies.
“The future should be one where communities can decide on their development agenda and futures. That’s the most important for me.” Dr Grey Magaiza, Deputy Director of the Centre for Gender and Africa Studies (CGAS) and Head of the Community Development programme on the Qwaqwa Campus, is passionate about capacitating communities to be agents of change and advancement. His vision for the future emphasises the empowerment of communities to take charge of their development by actively participating in decision making and the implementation of development projects that can improve their lives.
Since joining the UFS in 2008, Dr Magaiza has worked extensively on approaches that can foster the socio-economic transformation of societies. Over the years, he has crafted his research speciality into one that he is most proud of – being an interdisciplinary scientist immersed in the development of communities.
“I’m in a fortunate position of researching what I like. I say ‘fortunate’, because I’ve taken the time to understand what I’m passionate about, which is the overall field of rural livelihoods and livelihood futures – in short, community development. My research starts from an engaged university, understanding the elements that a university must use to enhance transformation and relevance to its immediate community in terms of development.”
One of the ways he has done this is by looking at social entrepreneurship as a development approach for young people in a rural setting. Through workshops with non-profit and civic organisations in Qwaqwa, Dr Magaiza has been helping these organisations to map out their needs and actively meet them through the involvement and support of external role players.
“We understand that communities are part of the national development agenda, but even that national agenda respects community knowledge and intentions and allows communities to shape their identity. A critical enabler of this is community organising. You bring back the capacity in communities to have dialogues on issues affecting them as spaces for engagement, knowledge exchange, and for people to just talk about their way forward.”
By enabling communities to define their development agenda, they can address their specific needs, challenges, and aspirations, he said. “When I look at livelihood futures, it’s quite an exciting aspect of my work – it’s like looking into a fortune tellers’ globe, because you’re not deciding for communities what they should do, but the communities themselves take those decisions.”
UFS researchers are producing various flavour and fragrance compounds

The minty-fresh smell after brushing your teeth, the buttery flavour on your popcorn and your vanilla-scented candles - these are mostly flavour and fragrance compounds produced synthetically in a laboratory and the result of many decades of research.
This research, in the end, is what will be important to reproduce these fragrances synthetically for use in the food and cosmetic industries.
Prof Martie Smit, Academic Head of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, and her colleague Dr Dirk Opperman, currently have a team of postgraduate students working on the production of various flavour and fragrance compounds from cheap and abundantly available natural raw materials.
Prof Smit explains that most of the flavours and fragrances that we smell every day, originally come from natural compounds produced mainly by plants.
“However, because these compounds are often produced in very low concentrations by plants, many of these compounds are today replaced with synthetically-manufactured versions. In recent times, there is an increasing negative view among consumers of such synthetic flavour and fragrance compounds.”
On the other hand, aroma chemicals produced by biotechnological methods, are defined as natural according to European Union and Food and Drug Administration (USA) legal definitions, provided that the raw materials used are of natural origin. Additionally, the environmental impact and carbon footprint associated with biotech-produced aroma chemicals are often also smaller than those associated with synthetically-produced compounds or those extracted by traditional methods from agricultural sources.
During the last four years, the team investigated processes for rose fragrance, vanilla flavour, mint and spearmint flavours, as well as butter flavour. They are greatly encouraged by the fact that one of these processes is currently being commercialised by a small South African natural aroma chemicals company. Their research is funded by the Department of Science and Technology and the National Research Foundation through the South African Biocatalysis Initiative, the DST-NRF Centre of Excellence in Catalysis and the Technology Innovation Agency, while the UFS has also made a significant investment in this research.
