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.

UFS Centenary 2004/05 : October snippets

2004-10-06

CENTENARY CONFERENCE
The proposed Centenary Conference on Democracy, Diversity and Development : Towards a mature and robust society – A critical discourse, refers. Unfortunately many invited contributors are unable to attend on the proposed dates (12 to 15 October 2004) prompting the UFS management to reconsider the timing of the conference. The UFS management has therefore decided to postpone this conference until an appropriate time in 2005.

As a result of this postponement the SAUVCA activities will also no longer be part of the October programme in Bloemfontein.

CENTENARY COMPLEX
The rehabilitation of the existing Reitz Hall and adjoining residence into the Centenary Complex is almost complete.

The inauguration of the complex – Reitz Hall and DF Malherbe House – will take place on Tuesday, the 12th of October 2004. A special open day from 11:00 until 16:00 is planned to enable all staff and students to visit this prestige complex. More detail will be available early October 2004.

FILM PREMIERE
The premiere of an UFS commissioned documentary, as part of its Centenary celebrations, on the remarkable leadership, reconciliatory and nation-building role of King Moshoeshoe, the Basotho leader of the nineteenth century, will take place on Wednesday, the 13th of October 2004. The director of this commissioned documentary is the well-known Max du Preez. Although this event is open to invited guests only, the documentary will also be screened by the SABC later this year. It will also be screened at several other occasions to enable staff and students to experience and discuss this film.

With this film and other projects the University of the Free State wishes to celebrate the legacy of this extraordinary African leader for the Free State and for South Africa.

CENTENARY HONORARY DOCTORATE GRADUATION CEREMONY
A special Honorary Doctorate Graduation Ceremony will take place on the 14th of October 2004 at 19:00 in front of the Main Building on the UFS campus. Twelve honorary doctorate degrees will be awarded to a diverse group of outstanding South Africans and international scholars. The Rector requests the attendance of all staff and students in large numbers during this prestige event.

The following candidates will receive an honorary doctorate degree: Me Antjie Krog, Prof Jakes Gerwel, Mr Karel Schoeman, Dr Frederick van Zyl Slabbert, Prof Saleem Badat, Dr Khotso Mokhele, Prof Robert Bringle, Prof Leo Quayle, Prof Jack de Wet, Prof Kerneels Nel (posthumous), Prof Boelie Wessels en Prof Jaap Steyn .
