“I love working with children.” This is one of the first things Annemarie le Roux mentions when asked to describe herself. This love for children propelled Annemarie into the field of education and she graduated in 2006 with a BEd in Foundation Phase at the UFS. Annemarie immediately immersed herself in the Deaf community, enriching the lives of children at the Thiboloha School for the Deaf in Qwaqwa and the De la Bat School for the Deaf in Worcester.
The academic world enticed Annemarie back to the University of the Free State (UFS) and she was appointed as a junior lecturer in the Department of South African Sign Language (SASL) and Deaf Studies in 2013. Going from strength to strength, Annemarie completed her master’s degree in SASL in 2019, and published an
article earlier this year that she co-wrote with Marga Stander. In this article, they found that SASL “has become an increasingly popular language that hearing university students want to learn as a second language” and subsequently explored different teaching methods used for this emerging group of interested students.
Although now firmly established in academia, Annemarie is still committed to the practical application of SASL. “I am closely involved in student and community engagement through the
SIGNALS Sign Language student association that helps empower the Deaf community and South African Sign Language.” She also interprets for the Deaf community whenever she gets an opportunity, as well as for Deaf students in class and meetings.
On the importance of Sign Language and the recognition of the Deaf community in South Africa, Annemarie believes it will open greater opportunities for development. “More people will be able to learn SASL, and it might even become a subject in school for hearing children.”
Using sugar to make the world a sweeter place

Besides it mainly being used for sugar production, sugarcane has emerged as an important alternative for providing clean renewable energy. Dr Deepack Santchurn, who works in the sugarcane breeding department of the Mauritius Sugar Industry Research Institute (MSIRI), believes if he could contribute towards a more environment-friendly and renewable energy through the use of sugarcane biomass, he would consider himself having made a great leap towards a better world.
Sugarcane is mostly known and exploited for the sugar in its cane stem. According to Dr Santchurn it is not the only thing the crop does well. “Together with certain grasses, it is the finest living collector of sunlight energy and a producer of biomass in unit time. Sugarcane is now recognised worldwide as a potential renewable and environment-friendly bioenergy crop.”
Significantly more bioenergy can be produced from sugarcane if the production system is not focused on the production and recovery of sucrose alone but on the maximum use to the total above-ground biomass. Diversification within the sugarcane industry is of paramount importance.
He has been able to identify a few high biomass varieties that can be exploited industrially. One of the varieties is a commercial type with relatively high sugar and low fibre in the cane stem. Dr Santchurn explains: “Its sucrose content is about 0.5% less than the most cultivated commercial variety in Mauritius. Nevertheless, its sugar yield and above-ground biomass yield surpass those of the commercial varieties by more than 24%. The genetic gains compared to commercial varieties were around +50% for total biomass yield and +100% for fibre yield. Its cultivation is strictly related to bio-energy production and the extracted juice can be used as a feed-stock for ethanol and other high-value products.”
Dr Santchurn received his PhD at the UFS’s Department of Plant Sciences during the Winter Graduation Ceremonies in June this year. His study leader was Prof Maryke Labuschagne from the Department of Plant Sciences.
