We are pleased to host Bertus Jacobs in our second episode of the Voices of the Free State podcast series. As Chief Technology Officer at IoT.nxt. (Internet of Things), Bertus’ mind is constantly searching for new techniques, and imparting these to his team of developers. Evident from his ‘always on’ approach, Jacobs has optimised his passion for turning ideas into mainstream realities. He co-founded a successful software company, CSS Software, which saw its humble beginnings grow from Bloemfontein-based to an international-footprinted company. CSS Software is regarded as having some of the most innovative products in its market segment and was acquired by a JSE-listed group.

François van Schalkwyk and Keenan Carelse, UFS alumni leading the university’s United Kingdom Alumni Chapter, have put their voices together to produce and direct the podcast series.  Intended to reconnect alumni with the university and their university experience, the podcasts will be featured on the first Monday of every month, ending in November 2021.  Our featured alumni share and reflect on their experiences at the UFS, how it has shaped their lives, and relate why their ongoing association with the UFS is still relevant and important. The podcasts are authentic conversations – they provide an opportunity for the university to understand and learn about the experiences of its alumni and to celebrate the diversity and touchpoints that unite them.

While studying towards his BScHons (Computer Science) at the University of the Free State, Bertus developed an SDK (Software Development Kit) with low-level integration into various graphics hardware.  

Bertus has researched many ways of contributing to the growing IT industry – from developing point-of-sale systems that still run today, qualifying as MCP and MCSE, engineering telematic and biometric solutions for clients (UFS was one of them). After being approached to consult in developing a solution for the government, his search for a certain hardware problem and his expertise in the IT realm resulted in his invention of a controller and the birth of the RAPTOR.  Reports that took eight weeks to compile previously, are now at the fingertips of those who need it – all through data harvesting and dashboarding that combines software and hardware. The world-changing RAPTOR delivers a complete IoT solution, which has been internationally validated as being at the forefront of the emerging IoT wave.  IoT.nxt was named Best Commercial and Best Overall Winner at the MTN Business M2M Awards in 2017.  

Stay tuned for episode three to be released on 5 April 2021.

Fire as a management tool questionable in arid and semi-arid grassland areas

The influence of fire on the ecosystem in the higher rainfall ‘‘sour’’ grassland areas of southern Africa has been well established. However, less information is available for arid and semi-arid ‘‘sweet’’ grassland areas, says Prof Hennie Snyman, Professor in the Department of Animal, Wildlife, and Grassland Sciences, about his research on the short-term impact of fire on the productivity of grasslands in semi-arid areas.

Sour and sweet grassland areas can be defined as receiving either higher or lower than approximately 600 mm of rainfall respectively. In quantifying the short-term impact of fire on the productivity of grasslands in semi-arid areas, a South African case study (experimental plot data) was investigated.

“Burned grassland can take at least two full growing seasons to recover in terms of above- and below-ground plant production and of water-use efficiency (WUE). The initial advantage in quality (crude protein) accompanying fire does not neutralise the reduction in half of the above-ground production and poor WUE occurring in the first season following the fire.

“The below-ground growth is more sensitive to burning than above-ground growth. Seasonal above-ground production loss to fire, which is a function of the amount and distribution of rainfall, can vary between 238 and 444 kg ha -1 for semi-arid grasslands. The importance of correct timing in the utilisation of burned semi-arid grassland, with respect to sustained high production, cannot be overemphasised,” said Prof Snyman.

In arid and semi-arid grassland areas, fire as a management tool is questionable if there is no specific purpose for it, as it can increase ecological and financial risk management in the short term.

Prof Snyman said: “More research is needed to quantify the impact of runaway fires on both productivity and soil properties, in terms of different seasonal climatic variations. The information to date may already serve as valuable guidelines regarding grassland productivity losses in semi-arid areas. These results can also provide a guideline in claims arising from unforeseen fires, in which thousands of rands can be involved, and which are often based on unscientific evidence.”
