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.

FS Premiers Documentary Film On Basotho King Moshoeshoe
2004-10-06

The University of the Free State (UFS) will premiere a documentary film on the legacy of King Moshoeshoe, Basotho leader of the nineteenth century for his role in nation-building and reconciliation on Wednesday 13 October 2004.

The hour-long documentary film, produced by the well-known journalist Mr Max du Preez, was commissioned by the UFS as part of its centenary celebrations.

“To us this film is a practical demonstration of the UFS’s commitment to the continued transformation of the campus, and its commitment to reconciliation and nation-building. It is seen as a contribution to one of the UFS’s key strategic priorities for this year, namely diversity, equity and redress,” says Prof Frederick Fourie, Rector and Vice-Chancellor of the UFS.

“Through these priorities, the UFS commits itself to developing a shared appreciation of the history of this country and to contribute to the establishment of the Free State Province as a model of reconciliation and nation building,” says Prof Fourie.

“King Moshoeshoe was a great African statesman and leader. He was born in this region of the country, but his influence and legacy extends way beyond the borders of the Free State, Lesotho and even way beyond the borders of South Africa,” says Prof Fourie.

Earlier this year the UFS launched a project to honor King Moshoeshoe. The project included among others the production of this documentary film, the possible presentation of an annual Moshoeshoe memorial lecture that will focus on African leadership, nation-building and reconciliation and PhD-level research into the life and legacy of King Moshoeshoe and a literary anthology including prose and poetry.

According to Prof Fourie the project will enable the UFS to give real meaning to words such as reconciliation, respect for the diversity of our languages and cultures, and the unity South Africans seek to build as a democratic nation through such diversity.

The documentary film on King Moshoeshoe will be screened on SABC 2 later this year.
