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.

The launch of a unique conservation project
2011-06-06

 

Our Department of Animal, Wildlife and Grassland Sciences launched a very special pilot project at Woodland Hills Wildlife Estate in Bloemfontein on Friday 03 June 2011, which aims to eventually aid in the conservation and study of one of Africa’s most graceful animals.

The project aims to provide the scientific basis needed for making future decisions in the best interests of the giraffe in the Kgalagadi Transfrontier Park in the Northern Cape and involves collaring and monitoring the behaviour and movement of these animals via GPS.

Based on the public interest in the giraffe and the increased impact of the growing giraffe population on the vegetation in the area, SANParks has been considering the translocation of a number of Kgalagadi giraffe. Due to limited information regarding their adaptation success and potential impact on their new environment, thorough planning and subsequent monitoring of the species is required.

Mr Francois Deacon from our university decided to undertake a PhD study to address the existing challenges. This will be the first study of its kind, undertaken on giraffe.

He says he decided on this project because of his love for animals and conservation. “There are nine sub-species of giraffe and seven of these are already endangered. I want to involve people and make them aware of the plight of the animals and the need for conservation,” he said.

The project kicked off on Friday morning, with a group of students and curious nature-lovers tracking a herd of giraffe at Woodland Hills. The challenge laid in identifying one of the animals which could easily be collared with a GPS device, tranquilising it, and applying the device, without harming the animal.

After a young bull was identified, it was up to Dr Floris Coetzee, a veterinarian, to get close enough to the animal to tranquilise it, and to the group of students to catch it and hold it down. All this was done perfectly and the animal was fitted with its new collars. The collars were designed and made by Mr Martin Haupt, who gained extensive experience in the design of similar collars for other research studies.

Mr Deacon will spend the following two weeks personally monitoring the animal constantly, to ensure that the collars do not cause any discomfort or injury and to determine whether it should be removed or adapted.

It has taken Mr Deacon over a year to plan the collaring process and the associated study. He says the main challenges in the project are financial, since it will cost approximately R500 000 to run over five years.

Thus far he has been supported by Mr Pieter Malan of Woodland Hills, Mr Cas Kempff of Cas Kempff Consulting Engineers and Prof. Frans Swanepoel of the UFS’ Directorate of Research Development, all of whom have been benefactors of the project.
Information gathered from the pilot project will provide the data to assess how to best fit the collar onto the giraffe to ensure that the animal is comfortable and that the collar will last in the wild.  Scientific data will be generated and processed for use by the Woodland Hills Wildlife Estate management.

Should the pilot project be successful, between four and eight giraffe in the Kgalagadi will be tracked using the satellite GPS collars. The GPS collars will enable the constant recording of the location of individual giraffe for up to 2 years. This will allow control and monitoring of the animals in real-time.

The main benefits of the project include, amongst others, improved decision-making, informing tourism development, education and community involvement, improved sustainability and improved cross-border collaboration between South Africa and Botswana.
