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.

Law students triumph in Africa

A team of students from the Faculty of Law at the University of the Free State (UFS) has won the first prize at the 16th African Human Rights Moot Court Competition held in Senegal last week.

The UFS team consisted of three L.L .B. students, namely Ms Lucy Nthotso, Ms Qaqamba Vellem and Mr Johnny Modipa, and beat teams from numerous South African law faculties as well as from the rest of Africa.

The Moot Court Competition is an event where students from law faculties across Africa argue a hypothetical case on human rights issues pertinent to the continent. This year’s competition dealt with the issues of refugee status, nationality, HIV/AIDS and the right to education.

Over and above the UFS team’s success as the overall competition winners, the UFS team came first in the written memorials category (written substance of the argument of the particular party), beating seventy teams from both the English and French speaking African countries.

To further add to their splendid overall team performance, team members Ms Vellem and Ms Nthotso were selected amongst the top fifteen students for their oral arguments out of the hundred and forty who took part in the competition. Ms Vellem came tenth and Ms Ntshotso eleventh.

According to the Dean of the Faculty of Law at the UFS, Prof. Johan Henning, the faculty is extremely proud of this achievement of its students in such a highly regarded competition.

“This success shows that the quality of legal education and training we provide here at the UFS, both through the 4- and 5-year L.L.B. options is rated among the best in Africa, if not the world,” Prof. Henning said.

He said it also showed that the faculty is committed to producing black law graduates of substance who are second to none.

The three students were coached by Ms Thapi Matsaneng, a UFS law graduate who is completing her Ph.D. at the University of London and who was groomed by the UFS as part of its Grow Our Own Timber programme, aimed at producing black academics.

Prof. Loot Pretorius, head of the department of constitutional law and philosophy of law at the UFS, acted as a consultant to the team. Ms Matsaneng also accompanied the three team members to Senegal.

The panel of judges who determined the winners comprised of the commissioners of the African Commission on Human and Peoples’ Rights, a South African Constitutional Court judge as well as other respected members of the legal community.
