Curiosity about environmental changes drives Dr Katlego Mashiane’s PhD research

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.

It’s Rag Time!

Kovsie Rag Community Service will start 2014 off with the well-known Rag festivities, with enthusiastic students already starting with float building in January. The theme for Rag CS 2014 is ‘Movies.’

As from 20 January, a cheerful atmosphere will be present at the Kovsie Rag farm, with senior and junior students working hard, while social cohesion is developing between them. Great entertainment will be part of these festivities, with the likes of DJ Euphonik and Adam performing on 31 January.
In the midst of all these activities, the annual ‘Chicken Run’ evening collections will take place on 21, 23 and 28 January, as well as the Ritsim sales in Bloemfontein and surrounding areas on 24-25 January.

The hard work will reach its peak with the judging of the floats on the morning of 1 February, after which the floats will depart at 09:00 for the first procession of the day. This route will end at Twin City Mall at 11:00, where 10 000 meals will be distributed to communities in Heidedal and Mangaung. Learners from Heidedal schools will entertain the public with their talents.

Our very popular family festival will already start at 16:00 with the opening of the gates at Chevrolet Park Cricket Stadium. Young and old will be entertained by well-known and vibrant artists, such as Robbie Wessels, Mango Groove, Zakes Bantwini, as well as a spectacular firework show. Come early to ensure a great spot on the grass.

The float winners will be announced at 17:00, whereafter the main procession of the day will depart from the Tempe robot in Nelson Mandela Drive at 18:00. The public can look forward to this ever popular procession through the streets of Bloemfontein, with decorated floats and students cradling collection tins proceeding to Chevrolet Park. The 2012/2013 UFS Rag queen, Mr Rag and their retinue will greet the public from the main float. Finalists for the 2013/2014 UFS Rag queen and Mr Rag titles, as well as drum majorettes, will also accompany the procession.

Do not miss out on this wonderful family festival – come early, bring your family and picnic blanket/chairs to ensure a great spot on the grass – a variety of refreshments will be on sale.

Tickets available from Computicket and entrance gates.

Tickets: R60 per person
R30 per child under 12

We would also like to make use of this opportunity to remind you of our vibrant 2013/2014 UFS Rag coronation ball, where the UFS Rag queen and Mr Rag CS for 2014 will be crowned on 14 February 2014 in the Callie Human Centre, UFS Campus.

Limited tickets will be available at R500 per couple and can be bought from the Rag Community Service office from 5 February 2014.
