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 Centre for Financial Planning Law (CFPL) in the Faculty of Law at the University of the Free State (UFS) awarded 342 Postgraduate and Advanced Postgraduate Diplomas in Financial Planning at this year’s graduation ceremony. The ceremony was held at the Sandtion Conference Centre in Johannesburg on 19 June 2012.

Some of the distinguished guests who attended were Dr Khotso Mokhele, Chancellor of the UFS, Dr Derek Swemmer, Registrar of the UFS, Prof. Nicky Morgan, Vise-Rector: Operations at the UFS, Prof. Helena van Zyl, Director of the UFS’s Business School, Prof. Rita-Marie Jansen, Acting Dean of the Faculty of Law and Adv. Wessel Oosthuizen, Director of the CFPL. The Chief Executive Officer of the Financial Planning Institute of Southern Africa, Mr Godfrey Nti, and the Chairperson of the Board, Mr Solly Keetse, were also present at the graduation ceremony.

Marilize Putter was named as the top student in the Advanced Postgraduate Diploma in Financial Planning Law, with Jenny White the top student in die Postgraduate Diploma in Financial Planning Law.

The UFS remains the largest institution in this field. The UFS’s Centre for Financial Planning Law is also the only institution in South Africa that presents the Postgraduate Diploma in Financial Planning Law as a pure specialisation diploma.

Donors who made the event possible include:

  •  Craig Bentley of Alexander Forbes
  •  Dev Chetty of Liberty Life
  •  Henry van Deventer of Acsis
  •  Tessa Pappenfuss of Lexis Nexis
  •  Bertie Nel of Momentum
