Curiosity about environmental changes drives Dr Katlego Mashiane’s PhD research

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.

In this week of graduation ceremonies, the University of the Free State had more than its academic achievements to celebrate. The Shimlas’ brilliant triumph in the Varsity Cup as well as the achievements by KovsieTennis and Kovsie Netball was celebrated at a colourful event on the Bloemfontein Campus.

At the celebrations, which were well supported by the campus community, the Vice-Chancellor and Rector, Prof Jonathan Jansen, congratulated all three teams on their outstanding achievements. Not only did the Shimlas walk off with the Varsity Cup, they also won every game they played. AJ Coertzen, the Shimlas’ captain, said: “Although we were well prepared and physically fit, the fact that we played for one another contributed much to our success. As a team, we have grown from friends to brothers.”

KovsieTennis was congratulated on wearing the USSA tennis crown for the fourth consecutive year. In addition, they have the following triumphs to their name: 2007 – SASSU (South African Students Sports Union) (Ladies); 2008 – USSA (University Sport South Africa) (Ladies) and 2009 USSA (Men). Duke Munroe, captain of the KovsieTennis team took the opportunity to thank the team personnel. He believes that hard work behind the scenes by the coach, Marnus Kleinhans, and the team manager, Janine de Kock, contributed greatly to the team’s success.

KovsieNetball was also praised for their successes. In 2014, under the captaincy of Karla Mostert, they won gold at the Varsity Netball championships. They also won the National Premier League. The UFS is also proud of its netball players in various national teams: SA Under 19-23, the Protea groups, and the SA University team.

At the celebrations, Karla said: “The environment and the people you surround yourself with dictate how easily you achieve success. Our achievements and successes are evidence of the quality of the coaches, supporters, and facilities available to us.

After the event on the Red Square, the teams made an appearance in the Callie Human Centre, where they were enthusiastically congratulated by graduands, their families and the university management. Dr Khotso Mokhele, Chancellor of the UFS, also praised the teams for their achievements. “You are a team without individual stars. That is the sort of team I want to be part of.”
