To inform, inspire, motivate, and connect!
These are the outcomes that the UFS Department of Alumni Relations wants to achieve through its Alumni Career Connect engagement series.
The series connects pre-alumni with leading alumni who have experience as leaders in various careers, entrepreneurship, personal and professional success.
The content and themes further aim to prepare pre-alumni for the world of work and life beyond graduation.
Dr Roy Jankielsohn is the Leader of the Official Opposition in the Free State Legislature and the DA Free State Provincial Leader. Formerly a Lecturer in the Department of Political Science at UFS (1995-2000), he was a Member of Parliament (2000-2006) during which he served as the DA’s Spokesperson on Defence and Safety and Security (Policing).
Join us as we experience Dr Jankielsohn’s personal and professional success.

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.
