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.

Prof Annie van den Oever envisions the future of film and visual media in her inaugural lecture
2014-02-07

The university formally welcomed Prof Annie van den Oever, an internationally-recognised film and media scholar, within its academic ranks. Her association with the UFS forms part of an exciting new postgraduate programme in film and visual media being created by the Faculty of the Humanities.

Prof Annie van den Oever delivered her inaugural lecture, “Foundational Questions for a Film and Visual Media Programme”, sharing her extensive knowledge in the field. The lecture attracted an international audience with people following the talk via live streaming from places such as Oslo, Berlin and London.

“Annie is quite a connected person through the film and visual media world,” Prof Lucius Botes, Dean of the Faculty of the Humanities, told the audience in the CR Swart Auditorium. He also referred to the fact that, under the auspices of Prof Van den Oever, two staff members from the faculty completed their master’s degrees at the University Groningen where she also teaches. “I am happy to announce that through Annie’s network we can invest in these young people.”

Prof Suzanne Human, Head of the Department History of Art, applauded the senior leadership for its vision to appoint Prof Van den Oever as extraordinary professor. “We have profoundly benefited and will still benefit from Annie’s obvious enjoyment in sharing her considerable experience and expertise in the design of a programme of film and media studies.”

The new postgraduate programme in film and visual media is being developed in partnership with the departments of Art History and Visual Culture Studies, Drama and Theatre Arts, English and the Department of Afrikaans, Dutch, German and French. The university aims to have the first film students enrol in 2015.
