Social justice is the promotion of just societies and treatment of individuals and communities based on the belief that we each possess an innate human dignity.

The power of research lies in the possibility to move from theory to practical outcomes that can change society for the better in some way. In essence, scholars have the ability to create the future in collaboration with government and civil society. At a recent international colloquium hosted by the University of the Free State (UFS) South African Research Chairs Initiative (SARChI) programme, researchers deliberated on social justice issues and possible resolutions.

Delegates from institutions across the UK, Zimbabwe, and Sweden presented findings from studies conducted around the world under the theme ‘Making Epistemic Justice: An international colloquium on narrative capabilities and participatory research’. The UFS SARChI Chair in Higher Education and Human Development Research Programme, under the leadership of Professor Melanie Walker hosted the colloquium from 21-22 November in Bloemfontein.

The importance of psychological liberation

In her welcoming address, Prof Walker quoted the late Black Consciousness activist, Steve Biko, who anticipated many of the current debates on epistemic power and exclusions when he wrote that “the most potent weapon in the hands of the oppressor is the mind of the oppressed”.

Prof Walker reiterated that epistemic justice matters, as affirmed by Kenyan writer, Ngũgĩ wa Thiong’o who in 1981 stated that, “colonialism imposed its control over social production of wealth through military conquest and subsequent political dictatorships. But its most important area of domination was the mental universe of the colonised, the control through culture, how people perceive themselves, and their relationship to the world”.

The relationship between storytelling and social justice

Dr Holly Henderson from the University of Nottingham in the UK was the first speaker to make a presentation, titled ‘Resisting the narrative conclusion in educational research’. According to Henderson, storytelling is an essential part of the long road to social justice.  

Henderson’s keen interest in the complexity of the narrative developed when she started working in further education many years ago. A significant part of her research focuses on the concept of ‘possible self’ which requires the art of storytelling in order to come to life. A study she conducted on university students delved deeper into this concept and found that environment plays a major role in the way individuals perceive the future. 

“The more detailed you imagine something, the more likely you are to achieve it,” said Henderson. However, the correct structures enable the future to be imagined. Hence, curriculum decolonisation, equal access to quality education, and social justice become all the more important in achieving future success among students globally.
 
The art of activism and advocacy 

The joint work of Dr Faith Mkwananzi from the UFS and Dr Tendayi Marovah from the Midlands State University in Zimbabwe looked at street art, otherwise known as graffiti, as a way to foster epistemic justice and collective capabilities among marginalised youth. 

According to Marovah, storytelling using art gives a voice to the voiceless and assigns dignity to the excluded. “Narrative offers an opportunity in which the unheard and unseen are heard and seen.”

Delegates of the colloquium unanimously agreed that researchers are in the business of providing much-needed direction on how to stop discrimination, challenging unjust government policies and the abuse of power, promoting peace instead of violence, eradicating poverty, opening access to quality education among other social justice issues. Therefore unity in research diversity provides fertile ground for manifesting social justice.

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
