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 newly elected Chairperson of the UFS Council, Mr Willem Louw, and Prof Francis Petersen, the incoming Vice-Chancellor and Rector of the UFS, were welcomed at this year’s official opening of the academic year which took place at the Bloemfontein Campus of the University of the Free State (UFS) on 3 February 2017.  

Prof Petersen, who will start his tenure at the UFS on 1 April 2017, was introduced to staff by the Acting Rector, Prof Nicky Morgan. Prof Petersen shared his future plans for the UFS with staff.

His vision for the UFS spells excellence. Among others, he seeks to establish an academic culture of excellence, underpinned by the pillars of diversity and inclusivity. “It is important that there should be respect for different convictions,” he said.

“The UFS should be a place where everyone feels welcome; a strong sense of belonging is needed. Staff and students should feel that they would like to make a contribution to make the UFS a strong university,” he said.

In order to address the institutional climate issue, Prof Petersen suggests that attention be given to the curriculum as well as transformation of the research culture. Research outputs should be expanded and diversified. Inclusivity from a community engagement perspective is also needed. “The things we are good at and in which we excel should be the anchors impacting our academic enterprise,” he said.

In terms of the physical environment, he said that spaces should be welcoming for students. “It is important that we sit with students to get their views and listen to their concerns,” Prof Petersen said.

To promote transformation at the university, the UFS management team is busy working on an integrated transformation plan to be submitted to Council in June 2017. As part of this process, consultations will be held with staff and students in order to incorporate their perspectives and convictions in the plan as well.

“It is important that there should be
respect for different convictions.”

Furthermore, it is important for Prof Petersen that the Qwaqwa and South Campuses should be more integrated with the Bloemfontein Campus. “The UFS is one university with three locations. The fact that it is one university should be reflected in our actions, attentions, and thoughts. Although there are geographical differences, all three campuses should receive the same resources and should deliver the same quality outputs,” he said.

Prof Petersen ended his speech by returning to the importance of academic excellence. “With the Academic Project we always strive for excellence. To achieve academic excellence, the focus is on both academic and support staff. In order to reach our goal, all staff should produce work of superior quality,” he said.

“I am a good listener who is outcome driven, with a vision that includes: diversity, inclusivity, academic excellence, and innovation”, Prof Petersen concluded.
