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.

SRC raises over R1 million for UFS underprivileged students
2016-01-18

R1.2 million has been raised by the University of the Free State’s (UFS) Student Representative Council (SRC) under the Right to Learn (R2L) campaign banner.

The SRC launched the R2L campaign on 30 October 2015,following the first wave of the #FeesMustFall movement protests against a proposed increase in tuition fees. The campaign was initiated to ensure that academically-deserving underprivileged students do not have to bear the brunt of deregistration, food insecurity, and the lack of textbooks.

To date, the student leaders have taken it upon themselves to appeal to lecturers, businesses, the community, and students alike to support its campaign. Each SRC member pledged R500 from their own purses when the campaign was launched.

Looking back at the #FeesMustFall movement

To the #FeesMustFall movement, which had gained momentum and resulted in a shutdown of many campuses across the country, President Jacob Zuma responded with a statement announcing a 0 % increase.

At the launch of the campaign, Lindokuhle Ntuli, the UFS SRC President, made a commitment to source financial aid for needy students.

“Even though the president said no fees will increase this year, we are still faced with the same challenges. No students who qualify should be de-registered this year. It is up to us to raise funds for the poor students to ensure that they get their right to education.”

Forward to the future: #AccessMustRise

By 4 April 2016, the SRC’s goal is to accumulate financial relief worth R5 million to counter the growing financial aid demand.

Given that more South Africans are extending a helping hand, the SRC President is adamant about gathering the sponsorships in two months. “It is possible if we push to market the campaign to gather R4.8 million,” said Ntuli.
