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.

Provisional registration period extended to 30 April 2012
2012-03-25

25 March 2012

After a week of intense negotiations between the senior leadership of the University of the Free State (UFS) and the Student Representative Council (SRC) of the Bloemfontein and Qwaqwa Campuses, the SRC has managed to persuade the senior leadership to extend the provisional registration period to Monday 30 April 2012.

This means that, until 30 April 2012, no students will be deregistered for not being able to pay their provisional registration fee. The initial deadline for students to register provisionally was 6 April 2012.

The SRC requested the extension of provisional registration and the senior leadership of the UFS agreed thereto for the following reasons:

  • To allow students more time to raise the money;
  • To allow the provincial and national government, as well as NSFAS more time to respond to students’ financial needs; and
  • To allow the SRC and the university more time to consult with students with strong academic records about financial aid options outside the university.

“The SRC is glad to note that the university management values our efforts in representing our students and we've been able to leverage that advantage to negotiate an extension of the deregistration date with management. We're happy that in this case management has responded to the appeal of students through the SRC and we're exceptionally proud of our ability to push student interests to unprecedented heights,” says Mr Richard Chemaly, SRC President of the Bloemfontein Campus.

According to Mr Chemaly, the SRC is confident in their negotiation abilities. “While others might strike and protest, it is in the best interests of our students to talk to the senior leadership about important issues that are in the interests of students,” he says.

“Since our request to extend the provisional registration period was approved by the university management, the SRC has been working tirelessly to ensure that no deserving student gets deregistered. This includes setting up external funds, approaching the Premier’s office for assistance and setting up the most extensive bursary database any SRC has ever had,” Mr Chemaly says.

If there are any parents or students in need of help for provisional registration, please contact Mr Chemaly at  chemalyra@ufs.ac.za.
