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.

With the recent procurement of SAB by Anheuser-Busch InBev SA/NV (AB InBev), a Belgian transnational beverage and brewing company, the 500L educational brewery located at the SAB Cyril Ramaphosa World of Learning, became available for donation. After an initial shortlisting of three universities, the SAB World of Learning Brewery was awarded to the University of the Free State (UFS) to be managed by Kovsie Brewing.

Prof Corli Witthuhn, Vice-Rector: Research at the UFS, approved the application for a micro-manufacturing liquor licence right in the middle of campus, which effectively put the UFS bid in a class of its own. It is part of her vision that entrepreneurial activities must be visible on campus”

Sixteen universities were approached to obtain the brewery for their respective campuses.

Kovsie Brewing is an initiative started by postgraduate students at the UFS Department of Microbial, Biochemical and Food Biotechnology in 2012. The main objective of this initiative was to expose BSc students to brewing as a practical application of the scientific fields presented at the department.

Kovsie Brewery entered into
the yearly  SAB Intervarsity
Brewing Competition. Kovsie
Brewing has won the best label
competition in 2013, 2014 and 2015
and was placed in the top three in
2016 and 2017.


First brewing and fermentation school
Dr Errol Cason, project leader at Kovsie Brewery, said: “Over the past five years the small-scale experimental brewery has steadily grown to the point where we obtained institutional support to establish the first Brewing and Fermentation School at the university.

Dr Cason explains that the primary role of Kovsie Brewing is to establish an accredited fermentation-based curriculum at the UFS to educate undergraduate and postgraduate students in the scientific process involved in the production of beer. “In addition, the donation enables Kovsie Brewing to provide practical job-related training and skills development on industrial grade equipment,” he said.

Emphasis on entrepreneurship
The secondary role is for Kovsie Brewing to function as a multi-disciplinary platform to stimulate the interaction between students from various fields of study. Currently Kovsie Brewing has well-established cooperative projects with both Marketing and Entrepreneurship programmes.

“In the future, Kovsie Brewing will expand on these multi-disciplinary interactions by incorporating other departments of the UFS with the focus on product development, logistics, as well as the legal aspects concerned with brewing,” Dr Jan-G Vermeulen from the Kovsie Brewery team said.

Corporate social investment representatives from AB InBev recently visited the university. Among others they met Drs Vermeulen and Cason. During their visit they also looked at other university projects, including the Department of Paediatric and Child Health and the Universitas Hospital, the Engineering Sciences Department and the Naval Hill Planetarium.

Khosi Mogotsi from AB InBev said: “It was wonderful to experience the passion with which UFS staff do their work.”
