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.

2014 Winter Graduation
2014-06-27

 
It is time for the 2014 Winter Graduation on our Bloemfontein Campus. From 2 – 4 July 2014 Masters and Doctoral degrees will be bestowed on graduates from across all seven faculties as well as the School of Open Learning. These include the conferral of Medicine degrees on the South African Cuban trainees.

Wednesday 2 July 2014 at 14:30: School of Open Learning
The School of Open Learning will confer a total of 609 degrees this year – almost double compared to the 320 of last year.

Thursday 3 July 2014 at 09:30: Faculty of Natural and Agricultural Sciences
Prof Magdalena Blum will receive an Honorary Doctorat, DPhil honoris causa, at this event. Prof Blum is an Extension Systems Officer in Rome. She works for a specialised agency of the United Nations called the Food and Agriculture Organization. This organisation’s mandate is:
• to improve nutrition,
• increase agricultural productivity,
• raise the standard of living in rural populations and
• contribute to global economic growth.

Her position serves to modernise and strengthen rural advisory services, their systems and networks worldwide. She has filled this position for almost nine years.

Prof Blum is driven by a passion for development, humanitarian work and female upliftment, but most of all, to enable people to help themselves.

Blum’s life has taken her from a small German village to Africa, Asia and Europe – and she has made an impact wherever she went.

Thursday 3 July 2014 at 14:30: Faculties of Economic and Management Sciences, Humanities, Education, Health Sciences, Law and Theology
At this ceremony, Faculty of the Humanities will award an Honorary Doctorate, DPhil honoris causa, on Prof Laura Mulvey. She is a feminist film theorist and worked at the British Film Institute for many years. She is currently a professor at Film and Media Studies at Birkbeck, University of London.

Prof Mulvey was prominent as an avant-garde filmmaker in the 1970s and ‘80s. In collaboration with her husband, Peter Wollen, she co-wrote and co-directed:
• Penthesilea: Queen of the Amazons (1974),
• Riddles of the Sphinx (1977, perhaps their most influential film),
• AMY! (1980),
• Crystal Gazing (1982),
• Frida Kahlo and Tina Modotti (1982), and
• The Bad Sister.

In 1991, she returned to filmmaking with Disgraced Monuments, which she co-directed with Mark Lewis.
