The late Prof Jaap Durand.
The management of the University of the Free State (UFS) is saddened to learn of the passing of Prof Jaap Durand, revered theological academic and author. Prof Durand obtained his master’s degree from the UFS and received an honorary doctorate in Philosophy from the UFS in 2004.
Prof Durand has had a colourful career as academic, writer, and struggle activist: from Professor of Systematic Theology and Dean of the Faculty of Theology at the University of the Western Cape to Deputy Vice-Chancellor of the same university. He also served as the ombudsman of Stellenbosch University from 2002 to 2003.
During his life, Prof Durand was a unifier and a critical voice, speaking out against injustice. He has also authored several books, including Dit is amper dag; Evolusie, wetenskap en geloof, and Protesstem.
The UFS joins the higher education community in mourning and is deeply saddened by the loss of such a great theologian and academic. We wish to convey our deepest condolences to Prof Durand’s family, friends, and loved ones during this time.
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.
