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.

You have the knowledge, which is a big resource, and should use it to the benefit of South Africa. This was the overwhelming message to graduates obtaining their master’s and doctoral degrees at the University of the Free State (UFS).

Their responsibility was emphasised by the likes of Justice Mahube Molemela during the ceremonies in the Callie Human Centre at the Bloemfontein Campus on 26 June 2017. Justice Molemela, Judge President of the Free State Division of the High Court and Acting Justice of the Supreme Court of South Africa, was the guest speaker at the morning and afternoon ceremonies.

The UFS conferred 388 master’s and 72 doctoral degrees on the final day of its mid-year graduation ceremonies, which was the biggest set of ceremonies in the university’s history. The doctorates came from the Faculty of Natural and Agricultural Sciences (30), Faculty of the Humanities (15), Faculty of Economic and Management Sciences (9), Faculty of Education (8), Faculty of Health Sciences (5), and Faculty of Theology (5). A total of 5 258 degrees were conferred over six days from 19 to 26 June 2017.

Future dependant on youth

Justice Molemela said the master’s and doctoral graduates have the skills to make a difference. “The future of a nation is largely dependent on its youth playing a meaningful role in creating a strong economy, culminating in a good standard of living for everyone.”

She said they should plough back into their communities and give opportunities to others. “I am certain that if each one of you thinks innovatively in your respective fields, you will find solutions which will eradicate poverty, improve service delivery, and hence our education will advance gender equity, and promote public participation.”

Dr Khotso Mokhele, UFS Chancellor, said these graduates have every reason to hold their heads high, their shoulders square, and walk with a bit of an attitude, as they have distinguished themselves.

Generation of new knowledge
According to Prof Francis Petersen, Rector and Vice-Chancellor, the UFS strives to be a university that is research led. “For me, one of the important aspects about universities which set them apart from other training and vocational institutions is the generation of new knowledge,” he said at a lunch function for PhD graduates on 26 June 2017. He feels it is critically important for them to make a contribution to the country.

Dipiloane Phutsisi, Principal and Chief Executive Officer of the Motheo TVET College in the Free State, also emphasised this. Phutsisi was the guest speaker on 23 June 2017. “Your courage and eagerness to face the future and tell the truth in the midst of this confusion, is highly desired by South Africans.”

Justice Ian van der Merwe, Judge of Appeal at the Supreme Court of Appeal and former Chair of the UFS Council, was the guest speaker at the ceremonies on 22 June 2017. He encouraged graduates from a chapter in the book War and Peace by Leo Tolstoy.

“There is no greatness where there is not simplicity, goodness, and truth (according to Tolstoy). Or maybe more modernly translated: There is no greatness where simplicity, goodness, and truth are absent.”
