Dr Sevias Guvuriro from the Faculty of Economic and Management Sciences at the University of the Free State (UFS) is the first UFS candidate to participate in the University of Michigan African Presidential Scholarship (UMAPS) fellowship programme. Dr Guvuriro is also a member of the Future Professoriate Group participating in the Transformation of the Professoriate Programme.  

About the project 

Dr Guvuriro’s main project during his five-month stay at the University of Michigan was on hazardous drinking and economic preferences among urban youth in South Africa. The project recognises that lifestyle behaviours in early life are important drivers of chronic disease later in life, and that harmful use of alcohol is among the main risk factors for non-communicable diseases in the world. According to Dr Guvuriro, persuasive behaviour-change approaches could be useful, especially in the context of developing countries, where the World Health Organisation’s non-communicable diseases ‘Best Buys’ interventions on alcohol use could be ineffective. Behavioural economics and experimental economics techniques could also be beneficial. "With the assistance of my host, Prof Erin Krupka from the University of Michigan School of Information, academics and other staff members, I have made very strong progress in analysing my survey and experimental data on the subject, which I obtained here in South Africa,” said Dr Guvuriro.

Unpacking UMAPS 

UMAPS offers African scholars drawn from across Africa the opportunity to spend five months at the University of Michigan, working and interacting with faculty members who are leaders in their fields. Each year, applications for the fellowship open on 15 August and close on 15 October. The programme started in 2009, hosting a single cohort each year. From 2020, the programme hosted two cohorts of about 15 African scholars each. These scholars are selected annually from an application pool of about 600. 

"It was an amazing experience, one that I wish all of my colleagues in the faculty and the institution at large could have," Dr Guvuriro said. “Other than meeting the faculty staff at the University of Michigan – who are amazing – I got to meet and interact with world leaders in the economics subdiscipline of my interest.” 

He concluded by stating that this is a rare opportunity for scholars, and although competitive, he believes it is worth applying for. “Although I was the first from the UFS to attend, I know that the August to December 2022 cohort has another UFS staff member, which is great. My wish would be for our university to be represented annually.”

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.
