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 appoints a Dean of Education
2009-11-06

 Prof. Dennis Francis,   Dean of the Faculty of Education at the University of the Free State (UFS).


Prof. Dennis Francis from the University of KwaZulu-Natal has been appointed as Dean of the Faculty of Education at the University of the Free State (UFS) as from 4 January 2010. He is the first dean of this faculty since it was established at the UFS earlier this year.

Prof. Francis has worked at the University of KwaZulu-Natal since 2002. Prior to his appointment at the UFS he was a Professor in the Faculty of Education and Head of the School of Social Science Education at that institution.

“I am overwhelmed and excited at the same time. Mostly, I feel privileged and honoured to be joining the Faculty of Education,” he said of his appointment.
“The Faculty of Education is newly constituted and there are endless possibilities and potential. So I am really excited to be here.”

“What attracted me to the UFS is the leadership and vision of Prof. Jonathan Jansen, the emergent energy that is here, and the possibilities for transformation and change that exist. But also the warmth and graciousness of the people that I have interacted with,” he said.

Prof. Francis has taught and supervised Master’s and Doctoral students in the area of social justice education, identity studies and sexuality education. He has published numerous articles in refereed national and international journals, chapters in edited collections, and four edited journal special issues. He is also the author of Between Race; Beyond Race. Prof. Francis is the current guest editor of the South African Journal of Higher Education Special Issue on Transformation and Social Cohesion in Higher Education.

He has delivered conference presentations in his fields of research at international conferences in India, USA, Brazil, Thailand, Greece, Malaysia, Mauritius, UK and South Africa, as well as a further fifteen papers at national conferences. At three of these conferences he was an invited speaker. In 2008 he was granted researcher status by the National Research Fund.

Prof. Francis is currently on the editorial boards of two journals and an advisor on two international education conference committees. He also serves as the Chairperson of the Kenton Education Association.
