Curiosity about environmental changes drives Dr Katlego Mashiane’s PhD research

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.

The Council of the University of the Free State (UFS) unanimously re-elected Judge Ian van der Merwe as its Chairperson for the next three years at its last meeting for this year on Friday, 16 November 2012.

Judge Van der Merwe is a Judge of the Free State High Court. He is an alumnus of the UFS and has been a member of the Council since 9 March 2007.

In accepting his appointment, Judge Van der Merwe said that he was honoured and humbled to lead a Council of this calibre for a second term. “The Council is setting a good example of what good governance at a higher education institution should look like. Meetings are conducted in good spirit and decisions made in the best interest of the university,” he said.

“Having sat on councils of many universities before, I can say with great surety that, on balance of expertise and backgrounds, the UFS has one of the most effective councils in the country and, to have a Chairperson of Judge Van der Merwe’s stature, is a privilege. His leadership and guidance is greatly appreciated,” said Prof. Jonathan Jansen, Vice-Chancellor and Rector.

Mr Edward Kieswetter, Group CEO and Executive Director of Alexander Forbes and Deputy Chairperson of the UFS Council, and Mr Jonathan Crowther (former editor of Volksblad) have been re-elected for a further term of four years in the category: "Appointed by the Council".

External Council members were given a tour of the Bloemfontein Campus after the meeting, followed by an induction session for new council members.

New Council members who joined this year are:

Derek Foster, in the category appointed by the Council
Ruben Gouws, elected by the non-academic staff
Lorraine Kriek, elected by the Alumni
Themba Mmabi, representative of the Minister of Higher
Education and Training
Sabelo Khumalo, SRC President, Qwaqwa Campus
William Clayton, SRC President, Bloemfontein Campus
Suraya Jawodeen, representative of the Minister of Higher
Education and Training
Mr Dan Mosia, representative of the Minister of Higher Education and Training
