Her love of numbers and analysing data – to such an extent that she, just for the fun of it, did university Mathematics in her spare time in Grade 10. This not only resulted in an A for Maths in matric, but also contributed to Walena Anesu Marambakuyana’s success during her postgraduate studies, as she was announced the best honours student in her year group in the Faculty of Natural and Agricultural Sciences. 

Solutions to Africa’s challenges

For this prestigious achievement, she was presented the Dean’s Medal, which she collected during the faculty’s graduation ceremony on 21 April 2022. “I can't begin to say how much this means to me. I think of the struggles that I've faced, and it just proves to me that anything is possible if you set your mind to it,” says Walena, who believes this achievement will also motivate her little sisters to aim higher in life. 

Walena, who completed her undergraduate studies in Actuarial and Financial Mathematics at the University of Pretoria, continued with her honour’s degree in Risk Analysis at the UFS.

“Thinking back, it was always clear that I would take this route. Throughout primary school and high school, the Math teachers particularly liked me. I think it was because they saw that I really enjoyed Mathematics. I also remember that at the tender age of seven, my dad's colleagues would call me a mathematician,” recounts Walena.

She, like her aunt and role model, Dr C Gandidzanwa, is working towards obtaining a PhD. Currently, Walena is enrolled for the master’s degree in Risk Analysis at the UFS. “In my view, a PhD would enable me to contribute to innovative ideas that will provide solutions to the various challenges we are facing in Africa and the world at large. I specifically would like to inspire younger generations coming after us to safeguard against risks by anticipating, assessing, and taking the necessary steps to mitigate against risks,” she says.

“I believe risk assessment and mitigation not only contribute to my day-to-day activities; it also affects bigger global challenges such as climate change. Through my studies, I have a clear picture of what can be done to mitigate these risks. However, the challenge is always to ensure that this filters to practical action,” says Walena.

This is where I belong

Receiving the Dean’s Medal for the best marks in the group of master’s students in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS), was another mathematician, Elize Swartz. “Receiving the Dean's Medal is a great honour for me. It reminds me that hard work pays off and it encourages me to continue with my studies.”

She completed her honours degree, majoring in Mathematics and Applied Mathematics, in 2019 and her master’s degree in Mathematics in 2021. For both, her mini thesis was in the field of graph theory.

Currently a lecturer in the UFS Department of Mathematics and Applied Mathematics, she is looking forward to starting with her PhD later this year. Elize, who already knew in primary school that she wanted to be a teacher, is hoping to one day be a full-time lecturer at the UFS. “My passion is to work with young people. I hope to make a difference in their lives by teaching, sharing my knowledge, and helping them in such a way that they experience the love of Jesus Christ,” she says. 

She continues: “I cherish the instances when my lecturers gave me advice, encouraged me, and recognised my hard work. I want to share and continue that positive experience with other people and students by teaching them to work hard and be responsible, while treating them with kindness, patience, and love.”

Her favourite part of studying was the moment when she did homework and assignment problems and everything just started to fall into place. “For me, Maths problems are almost like a little game or puzzle. I also enjoyed receiving my marks after each assignment, test, or exam, knowing that this was the result of all my hard work,” says Elize, who also enjoys campus life, especially after the lockdown, “walking on campus – feeling safe, at home, and the sense of knowing this is where I belong”.

A great honour was bestowed on a researcher at the University of the Free State (UFS) when he was invited to the preview of the documentary film, Last of the Longnecks. Dr Francois Deacon, lecturer and researcher in the Department of Animal, Wildlife and Grassland Sciences at the UFS, who also has a role in the film, attended the preview at the Carnegie Institution for Science’s Smithsonian National Museum in Washington DC, in the US, in March this year. The preview formed part of the DC Environmental Film Festival.

The Environmental Film Festival in the US capital is the world’s leading showcase of films with an environmental theme and which aims to improve the public’s understanding of the environment through the power of film. During the festival, the largest such festival in the US, more than 150 films were shown to an audience of 30 000 plus. 

Dr Deacon was invited by the producer of Last of the Longnecks to be part of a panel handling a question-and-answer-session about the film directly after the show. He described it as the greatest moment of his life. 

Role in the film Last of the Longnecks

“My role in the film was as the researcher studying giraffes in their natural habitat in order to understand them better, so that we may better protect them, and be able to provide better education on the problem in Africa,” says Dr Deacon. 

“Together with Prof Nico Smit, also from the UFS Department of Animal, Wildlife and Grassland Sciences, Hennie Butler from the Department of Zoology, and Martin Haupt from Africa Wildlife Tracking, we were the first researchers in the world to equip giraffes with GPS collars and to conduct research on this initiative,” he says. This ground-breaking research has attracted international media attention to Dr Deacon and Prof Smit. 

“Satellite tracking is proving to be extremely valuable in the wildlife environment. The unit is based on a mobile global two-way communication platform, utilising two-way data satellite communication, complete with GPS systems.

“It allows us to track animals day and night, while we monitor their movements remotely from a computer over a period of a few years. These systems make the efficient control and monitoring of wildlife in all weather conditions and in near-to-real time possible. We can even communicate with the animals, calling up their positions or changing the tracking schedules,” says Dr Deacon.

The collars, which have been designed to follow giraffes, enable researchers to obtain and apply highly accurate data in order to conduct research. Data can be analysed to determine territory, distribution or habitat preference for any particular species.

Over a period of three years (2014-2016), the Last of the Longnecks team from Iniosante LLC captured on film how Dr Deacon and his team used the GPS collars in Africa to collect data and conduct research on the animals.

“With our research, which aims to understand why giraffes are becoming extinct in Africa, we are looking at the animal in its habitat but not only the animal on its own. If the habitat of these animals is lost, they will be lost as well. Therefore, our focus is on conservation and better understanding the habitat. The giraffe is only a tool to better understand the habitat problem,” says Dr Deacon. 

Since the beginning of his research Dr Deacon and his team have had six new collar designs, with animals in four different reserves being equipped with the collars. The collars use the best technology available in the world and make it possible to determine how giraffes communicate over long distances, and how their sleep patterns function. Physiological and biological focus is placed on the giraffe’s stress levels, natural hormone cycles, and milk quality in cows.

Experience at the film festival

“Absolutely amazing. Totally beyond our frame of reference as South Africans.” This is how Dr Deacon describes his experience of the three days in Washington DC during the film festival.

“It was an absolute honour to be part of the global preview of the film and to be able to work with Ashley Davison, the director of the film, and his team. I am just a rural farm boy who dreams big, and now this dream is known worldwide!” he says. 

The film, which will be launched in April, will be screened in South Africa on the National Geographic channel in May 2017. Meanwhile, the film will also be shown at eight other film festivals in the US. 

Work will start on a follow-up documentary in October and Dr Deacon is excited about the prospect. A mobile X-ray machine will be available from October. Internal sonars could also be performed on each of the animals. Researchers from around the world will form part of the team which will be led and co-ordinated by Dr Deacon and his co-workers at the UFS.
