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.

UFS provides support network in each faculty

Faculties at the University of the Free State (UFS) have been affected differently by the interruption of teaching time over the past few weeks.

Some faculties, like the Faculty of Law, have completed their curriculum, while other faculties like the Faculty of Natural and Agricultural Sciences require more teaching time. The Faculty of Health Sciences, for instance, cannot do teaching through alternative modes of delivery.

According to their needs, each faculty has prepared all the necessary learning material and instructions to support student learning. The standard and quality will be the same as if students have been attending classes. Some faculties require practical laboratory work as part of their curriculum and the necessary arrangements and adjustments have been made per department/faculty.

Constantly check official platforms
In order to assist with successfully completing the 2016 academic year, the UFS has launched the Academic Reboot Pack 2.0. It provides information around the carefully-crafted UFS academic rescue strategy and how to go about completing your work.

It is paramount to constantly check your faculty’s Blackboard organisation, the university’s main page, and your ufs4life emails to stay informed with emerging information regarding the state of the campus.

Faculties communicate work directly
Faculties at the UFS will communicate all outstanding academic work directly to the students registered in the faculty. For this, the university has created a UFS Support Network. Students should not hesitate to email or call if they need support.
