Dr Katlego Mashiane
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.

Zakes Mda honoured at UFS Summer Graduation
2013-11-21

 
The awarded author, Dr Zakes Mda, received his honorary doctorate at the University of the Free State at the December Graduation Ceremony. Pictured here with him is Dr Khotso Mokhele, Chancellor of the UFS.

On Thursday 5 December 2013, the University of the Free State (UFS) will award more than 300 degrees and qualifications during the Summer graduation at the Bloemfontein Campus.

The graduation will take place during two ceremonies in the Callie Human Centre, where master’s and PhD degrees will be awarded during the first ceremony at 10:15 and diplomas, certificates and undergraduate qualifications awarded to students from the School of Open Learning and the Faculty of Health Sciences at 14:30.

An honorary doctorate from the UFS will also be bestowed on the author, Dr Zakes Mda, during the morning ceremony.

Dr Mda is a South African literary icon and public intellectual with extraordinary local and international influence. Mda’s contribution to world literature and contemporary South African public life resonates powerfully with some of the fundamental principles of the Academic and Human Projects articulated in the strategic thrust of the University of the Free State, which makes him an ideal candidate for an honorary doctorate from our university.

Some of his most famous works include Ways of Dying, Heart of Redness, The Madonna of Excelsior, The Whale Caller, Cion, Black Diamond and his recent memoir: Sometimes There is a Void: Memoirs of an Outsider.

The Springbok rugby player, Jannie du Plessis, will address graduandi during both ceremonies.
