Delegates at the workshop were provided opportunities that many larger conferences do not offer.

The growing body of work examining microvariation in African languages prompted Dr Kristina Riedel and Dr Hannah Gibson, from the University of Essex and research fellow, to work on a research project, “Variation in Sesotho and Setswana as spoken in the Free State”, to document the dialectal variation in the languages as it is spoken in the province. 

“Dr Gibson and I have a joint research project which is funded by a Newton British Academy mobility grant,” says Dr Riedel, Head of the Department of Linguistic and Language Practice at the University of the Free State (UFS).

The duo hosted a workshop on morphosyntactic microvariation (small structural differences that can be observed between closely related languages or dialects) on the UFS Bloemfontein Campus, as part of the Newton Fund research project.  

Research focus on dialectal variation 

Dr Riedel says there has been some linguistic work on both of these languages. “But for Sesotho, linguists have noted that there is no dialectal variation. This seems hard to believe given the size of the population who speak the language,” she says. 

They are looking at speakers in the Free State province for differences in both languages. Speakers themselves also report awareness of dialectal differences and variation between different regions. “We’re also interested in whether they have influenced each other – particularly in places where people speak both of these languages on a day-to-day basis, such as Thaba ’Nchu and Bloemfontein,” Dr Riedel says.

Dr Riedel believes that in the context of an African university it is important to contribute to the development, teaching and support of African languages. “Research on African languages can play an important part of this picture. Furthering our knowledge and understanding of African languages from a linguistic perspective also contributes to our understanding of the world’s languages and linguistic diversity.” 

Workshop creates space for training and skill sharing

The aim of the workshop was to bring together researchers, students and language practitioners to “provide them with some of the insights and training that is helpful when looking at morphosyntactic microvariation”, Dr Riedel says.

The workshop was conducted in two sets. At the first workshop the emphasis was on training and sharing of skills and the second part focused on more research-related presentations. 

The workshop, which took place on 19 July 2019, was attended by delegates from numerous local institutions (Rhodes University, University of the Western Cape and Stellenbosch University) as well as universities in the rest of Africa including the University of Malawi, Dar es Salaam University College of Education and Makerere University in Uganda.

Plant-strengthening agent enhances natural ability of plants to survive
2015-07-27

Drought, diseases, and fungi. These are factors that farmers have no control over, and they often have to watch despondently as their crops are damaged. In addition, the practice of breeding plants in special and strictly-controlled conditions, has resulted in crops losing the chemical ability to protect themselves in nature.

Researchers in the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS) have developed an organic agent that restores this chemical imbalance in plants. It enables the plant to build its own resistance against mild stress factors, and thus ensures increased growth and yield by the plant.

ComCat®, a plant-strengthening agent, is the result of extensive research by the German company, Agraforum AG, together with the UFS. Commercialisation was initially limited to Europe, while research was done at the UFS.

“Plants have become weak because they were grown specially and in isolation. They can’t protect themselves any longer,” says Dr Elmarie van der Watt from the department.

Dr Van der Watt says that, in nature, plants communicate by means of natural chemicals as part of their resistance mechanisms towards various stress conditions. These chemicals enable them to protect themselves against stress conditions, such as diseases and fungi (biotic conditions) or wind and droughts (abiotic conditions).

Most wild plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent.

The European researchers extracted these self-protection chemicals from wild plants, and made them available to the UFS for research and development.

“This important survival mechanism became dormant in monoculture crops. ComCat® wakes the plant up and says ‘Hey, you should start protecting yourself’.”

Research over the last few years has shown that the agent, applied mostly as a foliar spray, subsequently leads to better seedlings, as well as to growth, and yields enhancement of various crops. This is good news for the agricultural sector as it does not induce unwanted early vegetative growth that could jeopardise the final yield ? as happened in the past for nitrogen application at an early growth stage.

“The use of synthetic agents, such as fungicides which contain copper, are now banned. Nowadays, options for natural and organic agriculture is being investigated. This product is already widely used in Europe, but because farmers are often swamped by quacks, the South African market is still somewhat sceptical.”
