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.

Any phase in a learner’s life can be the right time to explore science. As for Grade R learners at Nzame Primary School in Mangaung, it all started when their Deputy Principal, Charles Busack, attended the Global University for Lifelong Learning (GULL) workshop coordinated by the university’s Community Engagement in October 2016. The GULL network enables its affiliated organisations to recognise the individual and collective efforts of those who are creating progressive transformation in communities and in the workplace. Consequently, a community-based initiative, Science4Fun, was developed and launched at the primary school, where learners would start to experiment with science through play.

University students instrumental in teaching
Every Tuesday morning, these fun science activities form part of the foundation phase programme, in which Dr Elizabeth Conradie of the Central University of Technology (CUT) and four postgraduate Science students from the UFS, engage teachers and learners in exciting experiments and demonstrations. 

Most people just know pyramids as big, impressive structures built a long time ago in Ancient Egypt. However, for Grade R learners at Nzame Primary, their basic Geometry insight about shapes advanced to engineering skills when they built modern pyramids, connecting jelly sweets and sosatie sticks.

Laying a foundation for the future
According to Dr Conradie, more fun exercises are lined up for curious minds, exploring other sciences such as Chemistry and Mathematics, combined with music. The initiative will assist to equip learners with the basics of Science into more advance learning phases of the schooling years, giving them an advantage.
