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.

Making a difference is the most important thing for Gary Kirsten

“Can I make a difference in someone’s life?” This was the central driving force for Gary Kirsten, head coach of the 2011 World Cup winning Indian cricket team. He currently coaches the Proteas.

Gary was the first guest speaker at a new series of lectures at our Business School. Challenges and solutions in management will be highlighted in the series. In his lecture, Gary was interviewed by Prof. Johann Coetzee, Extraordinary Professor at the Business School. The audience got a glimpse of the person often seen on television screens and they travelled with him from his childhood days at the Newlands Cricket Ground to his days in New Delhi as head coach of the Indian team.

His challenge in India was to develop a new culture in a team with very valuable and expensive brands. His light-bulb moment occurred on a team-building visit to Australia. His question to the team was what he could do for them and what they would expect from him. The turning point was Sachin Tendulkar’s answer: I would like you to be my friend. Tendulkar’s wife’s comment on the winning night was the proof of his success. She said: “The last three years were the happiest in my husband’s life.”

Gary said it was an incredible privilege to make a difference in people’s lives. “I wake up asking myself where I can make a difference in someone’s life. You must create an environment for people to enjoy the game, challenge one another and thrive.”

He is confident that the Protea team has the potential to be a great cricket team. He said the upcoming England tour is a test. “This tour will test us to be the top team in the following years. I would like to set them up for the best chance to win.”
