Dr Katlego Mashiane
Striving to make a difference in the field of biodiversity conservation, Dr Katlego Mashiane decided to pursue a PhD in Geography, focusing on the spatial modelling of grassland diversity and nutrients in subalpine environments. He received his PhD during the recent April graduation ceremonies on the Qwaqwa Campus.

In the small village of Ga-Mabotia about 25 km outside of Polokwane, Dr Katlego Mashiane grew up, surrounded by rocky mountains characterised by boulder outcrops, where he interacted with nature from an early age. 

He recently obtained his PhD, majoring in Geography, from the University of the Free State (UFS), which was conferred on him during the April graduation ceremonies that took place on the UFS Qwaqwa Campus. The title of his dissertation is Grass nutrients estimation as an Indicator of rangeland quality using satellite remote.

Predicting the presence of biodiversity and nutrients in an area

Based on the principle that diverse grasslands tend to perform better, environmental changes threaten the resilience and services these grassland ecosystems provide. The study examined how many different types of plants and animals can be found at a particular place to enhance our understanding of the ecosystem’s value to humans, and that biodiversity loss will reduce these ecosystem services. Focusing on spatial modelling of grassland diversity, Dr Mashiane specifically investigated the influence of topography and remotely sensed satellite data on species richness and diversity in subalpine environments, and how they are affected by the availability of grass species. To determine this, he used a random forest machine-learning algorithm to find the best information in the data that could be used to estimate the levels of species richness, diversity, and nitrogen in a protected national conservation park. 

His study discovered that some data types – such as the near-infrared variable and certain vegetation data (EVI and SAVI) – were especially useful for determining the number and variety of species in a certain area. With this information, scientists can create models that predict the presence of different types of biodiversity and nutrients in an area.

Playing a key role in protecting our natural assets

Equipped with this knowledge, one will be able to understand how to protect and preserve different types of biodiversity and promote the nutritional value of both plants and animals in the environment. “Land managers could use this information for conservation strategies,” states Dr Mashiane, who decided to pursue this study because he was curious about how environmental changes will affect species.

“Grasslands provide important ecosystem services underpinning human well-being, and therefore warrant our protection; I would like to play a role in protecting our natural assets and contribute to understanding our biomes, especially in the context of global change,” he says.

In the next five years, Dr Mashiane plans to pursue further research and mentor other students in his field of study.

There is a need among visiting international students and foreign visiting lecturers and researchers to be able to speak Afrikaans. According to Prof Angelique van Niekerk, this is the reason why the Department of Afrikaans and Dutch, German and French at the University of the Free State (UFS) has been offering short courses in Afrikaans on campus for more than 15 years.

As from January 2018, those people wishing to learn Afrikaans outside of the UFS campus will be able to do so fully online. This is the first time that Afrikaans can be learnt fully online. The course is part of a short learning programme, Gesellig Afrikaans 1 and 2, which has been presented at the UFS since 2007. It is presented with the support of the Virtual Institute for Afrikaans (VivA), and Afrikaans can now be learnt as foreign language globally.

Need to speak Afrikaans
 
Prof Van Niekerk, Head of the Department of Afrikaans and Dutch, German and French, believes people who come in contact with the language have a need to learn to speak Afrikaans. “Afrikaans is a vernacular in the workplace, education, and social circles, especially in Bloemfontein, the Free State, and South Africa,” she says.

On average, 15 students per semester are enrolling for the existing contact-based course. Prof Van Niekerk says these students are from countries such as The Netherlands, Belgium, Germany, France, Poland, Lesotho, Zimbabwe, and some are from the East.

English used as teaching medium 
In 2018, the 20-week course will be taught online via the VivA website or on campus through contact sessions (within 13 weeks). “The online course for international students is currently being marketed for the first time, and in 2018 we will officially be enrolling international students for the online course from beyond UFS borders,” says Prof Van Niekerk.

The teaching medium will be English, with all the information and explanations taking place in Afrikaans and English. Supporting material such as Afrikaans films, music, pronunciation guidelines, and continuous self-assessment are part of the online course material.
