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 Disaster Management Training and Education Centre for Africa (DiMTEC) at our university, recently launched its Art on Disasters initiative at the Gallery on Leviseur in Bloemfontein. 

Disasters have a devastating effect on societies and are accompanied by fear, uncertainties and often post-traumatic stress disorders. The creative arts have the ability to comfort survivors and those affected by tragedy. Amid disaster, art serves as a memorial, aids in the healing process and helps these communities to interpret their emotions. 

This is precisely the main focus of the Art on Disasters project. It aims to develop paintings, sculptures, dramas, theatre productions, poetry and music in collaboration with artists. These productions will then be presented to communities at risk of, or affected by, disasters, to create awareness and foster healing. 

Furthermore, the initiative will conduct research on art as a form of therapy and co-ordinate rehabilitation experts to assist the relevant communities. The artworks collected by the project, will be sold or auctioned to help raise funds. The proceeds will then be donated to a worthy cause as part of DiMTEC’s commitment to community service. 

The project will help console and heal communities and aspire to generate greater resilience to trauma. It will also give humanitarian workers the opportunity to advocate for disaster risk reduction and offer them an opportunity for psychological debriefing after attending to affected communities. 

“We will collect different categories of art related to all forms of disasters. These include paintings, photography, sculptures, poetry, music, theatre productions and short stories,” said Dr Andries Jordaan, Director of DiMTEC. “Stephanie Peters, Thomas Hart Benton, Tania Kovats and Medhi Naimi are just a few of the many artists that paint on man-made and natural disasters. They are artists that believe in art therapy as a form of self-expression, well-being and recovery,” he added. 

For more information about this initiative, or to possibly contribute as an artist, please contact Olivia Kunguma from DiMTEC on +27(0)51 401 9699 or kungumao@ufs.ac.za .
