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.

Colloquium focuses on rural education

Some of the international delegates during the second annual colloquium on rural education recently held at the Qwaqwa Campus.
10 October 2012

 The second edition of the Sustainable Rural Learning Ecologies (SuRLEc) Colloquium was held at the University of the Free State's Qwaqwa Campus this week. This three-day international event provided the Faculty of Education's postgraduate students with a platform to present their research and to learn from experienced researchers from all over the world.

In his opening address, the Faculty's Programme Head, Dr Dipane Hlalele, challenged all delegates to translate their research into achievable goals to address all the challenges facing rural education.

"Excellence in teaching and learning in a rural context remains a challenge for all sectors and levels of the education endeavour," Dr Hlalele said.

"Urban and metropolitan schools, colleges and universities may unintentionally structure their learning programmes in such a manner that they neglect rural attributes. This results in the marginalising of learners and students from rural environments. To complete the loop, these institutions are more likely to fail in preparing graduates for decisive contributions to sustainable rural learning ecologies," Dr Hlalele added.

The colloquium was officially opened by the Vice-Rector: External Relations, Dr Choice Makhetha, who highlighted the fact that the UFS was already doing its bit in levelling the learning playfields in higher education.

"We are aware that many of our students who come from disadvantaged backgrounds find it hard to cope at university. As a result, we are not waiting for them to come through to us. We are already in partnership with a number of schools where we help learners to improve their results," Dr Makhetha said.

The crucial role played by rural teachers was celebrated during a gala dinner to honour and acknowledge their efforts despite a myriad of daily challenges.

Ms Jabulile Mabaso (The Mills Primary Farm School) was honoured for 'Excellence in multi-grade teaching in Foundation and Intermediate phases'. Ms Rekha Mathew (Sibonakaliso Primary Farm School) and Mr Andries Motsoere (Tshebedisano Primary Farm School) were awarded for 'Excellence in managing multi-grade curriculum'.

The 2012 SuRLEc Honorary Award went to Ms Motshedisi Damane for her valuable contribution to the development of rural education in the Thabo Mofutsanyana Education District. Last year's recipient was the Dean of the Faculty of Education, Professor Dennis Francis.

Delegates and keynote speakers came from Thailand, Malaysia, the Unites States of America as well as the SADC countries of Botswana, Zimbabwe and Lesotho. South Africa was represented by the Universities of the North-West, Limpopo, KwaZulu-Natal and CUT, amongst others.
