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.

UFS Alumni honours four
2007-02-19

 Mr Corrie van Zyl, former South African fast bowler and assistant coach of the national cricket squad, will be honoured by the Alumni of the University of the Free State (UFS) as Kovsie Alumnus of the Year 2006.
 
The award is made to Mr Van Zyl for his outstanding contribution to cricket. Under his guidance the Gestetner Diamond Eagles performed excellently and won five out of the six national one-day cricket tournaments they took part in.
 
The Cum Laude Award, awarded from time to time to any alumnus for outstanding service or achievement at local, national or international level in his/her specific career domain, will be awarded to Messrs Zingile Dingani and  Deon Meyer.
 
Mr Dingani will receive the Kovsie Alumni Cum Laude Award for his influential position in the government of South Africa as secretary of Parliament.  As former MEC for Finance in the Free State, he performed significant leadership roles in transforming the Free State economy. The Mail and Guardian described him “as a high performer who is likely to become the next Provincial Premier”.
 
Mr Deon Meyer, acclaimed South African suspense novel writer, will also receive a Kovsie Alumni Cum Laude Award for 2006.  Mr Meyer received numerous acknowledgements and awards for his contribution to literature on both national and international level.
 
Prof Helena Van Zyl, Director of the School of Management at the UFS, receives the Kovsie Alumni National Management Award for exceptional service during 2006.  Through her extraordinary abilities and leadership skills, Prof Van Zyl has managed to build the School of Management at the UFS to one of the most reckoned management schools countrywide.
 
The award ceremony will take place on Friday 9 March 2007 during a gala award banquet in the Reitz Hall of the UFS Centenary Complex on the Main Campus in Bloemfontein.  
 
All alumni of the UFS are welcome to attend the function. The guest artists will be various talented Kovsies and the entrance fee of R100 per person includes a three course meal.  
 
Those who are interested can contact Ms Annanda Calitz at 051 401 3382 or alumni@ufs.ac.za.
