Muthianzhele Ravuluma receives an award from Prof Sebastian Leuzinger from the Auckland University of Technology in New Zealand.

A PhD student from the University of the Free State (UFS) has won the International Society for Horticultural Science (ISHS) Young Minds award for the Best Paper and Best Poster Presentation during the 12th International Workshop on Sap Flow, which was held in Rotorua, New Zealand.

Muthianzhele Ravuluma from the Department of Soil, Crop, and Climate Science who is working on his PhD in Agrometeorology, presented a paper on “Sapflow Dynamics of Young and Mature Pomegranate Trees Under Irrigation” during the four-day symposium that took place between 30 October and 3 November 2023. Agrometeorology is the study of the soil, plant and atmosphere continuum. In simple terms, it is called agricultural meteorology, which is the study of the influence of weather and climate on agriculture.

Encourage do and learn more 

“I feel thankful to being given an opportunity like this, and winning the award was a surprise. Still, I am happy and grateful for the support from my promoters and the Pomegranate Water Use Project members. This encourages me to do more and to learn more about new technologies in the field of agriculture,” he says. 

Ravuluma travelled to New Zealand with his promotor Dr Phumudzo Tharaga to present his research and to learn from other researchers is the field. His research looks at the water use of pomegranate trees under irrigation in a Mediterranean climate. 

A proud Dr Tharaga says he is happy to know that the guidance he has been giving to Ravuluma is fruitful and improving his academic and research capabilities. “I feel proud as a supervisor, which makes my dream come true of ensuring that all postgraduate students can showcase their work on international stages,” says Dr Tharaga. 

Hosting next symposium 

Together with Prof Rob Skelton from Wits University, they also successfully bid to host in the 13th International Sap Flow Workshop in South Africa – beating China and the US in the process. All three colleagues will collaborate as conveners of the workshop in South Africa during October/November 2026. 

“It is an honour to be recognised and entrusted by the international community of scientists who would like to showcase their work in South Africa. As the convener of the conference, I am happy that it will be hosted in our country for the first time since the inception of the Sap Flow Working Group. Scientists and researchers in South Africa will be able to interact with their peers from different parts of the world,” concludes Dr Tharaga.

Dr Phumudzo Tharaga congratulates Muthianzhele Ravuluma on winning the  prestigious award.

Prof Melanie Walker, Senior Research Professor at the University of the Free State’s (UFS) Centre for Research on Higher Education and Development (CRHED) has received an A1 rating from the National Research Foundation (NRF). This rating acknowledges Prof Walker as a leading international researcher – her work unequivocally recognised by peers world-wide for its high quality and wide impact.

This is the first time in our institution’s history that two A-ratings are awarded simultaneously. Prof Maxim Finkelstein from the Department of Mathematical Statistics also recently received an A2-rating in Probability and Statistics from the NRF.

“Achieving this outstanding rating,” Prof Walker says, “is not just an individual achievement. I have had tremendous personal support and rich intellectual collaborations from wonderful colleagues on the way. The award also recognises the Rector’s project to build a dynamic research culture at UFS.”

Prof Walker has been researching and writing about issues in education and higher education for over 20 years. In particular she is interested in opportunities into, through and beyond education across dimensions of dis/advantage, and how higher education contributes to building a decent society by removing inequalities in its own policies and processes.

Through her focus on capacity building – around the common theme of higher education, human development and social justice – Prof Walker is developing a dynamic cohort of new-generation scholars. Her research group of graduate students and post-doctoral fellows is drawn from countries not only in Africa, but as far afield as Finland, India and Vietnam.

Her networks attract international scholars to the UFS, who contribute to research projects, engage graduate students, and add a considerable contribution to research at our university.

In addition, Prof Walker fulfils a host of roles, which includes:

• Tier One National Research Foundation (NRF) Chair in Higher Education and Human Development.
• Vice-President of the international Human Development and Capability Association (HDCA).
• Fellow of the Academy of Science of South Africa (ASSAf).
• Honorary professor, University of Nottingham, UK.
