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.

Research conducted on economic impact of recent international soccer and rugby matches for Bloemfontein

2004-09-09

The Centre for Development Support at the University of the Free State (UFS) recently conducted a survey on the economic impact of the international soccer and rugby games that were played in Bloemfontein earlier this year.

The research focused on the soccer match between Bafana Bafana and the Cape Verdic Isle and the rugby match between the Springboks and Ireland .

“The survey was done as a result of a research agenda about local economic development in Bloemfontein ,” said Dr Lochner Marais, researcher at the centre.

“We conducted the research by doing 402 interviews with soccer supporters and 376 interviews with rugby supporters from outside Bloemfontein ,” said Dr Marais.

The centre distributed questionnaires, collecting the following information on the soccer and rugby supporters: their age, gender and origin, the number of nights spend in Bloemfontein , their household expenditure in Bloemfontein and their rating on the quality of service.

“It is estimated that 10 800 soccer supporters and 27 000 rugby supporters came from outside Bloemfontein . Of the rugby supporters 14,4% were female and 85,6% were men. For the soccer international the percentage was 33% females and 67% males,” said Dr Marais.

The highest number of people who came to watch the soccer game in Bloemfontein (35,8%) was from the Northern Free State . The rugby supporters mainly came from Gauteng (21,8%) and the Northern Free State (18%).

When visiting Bloemfontein soccer supporters spend R912 per household, whilst rugby supporters reached deeper in their pockets and spent R1 807 per household.

“The survey indicated that the two international matches resulted in approximately R58 million been spent in Bloemfontein . Rugby supporters were accountable for the largest part (R48 787 205) spent. The largest chunk of the money spent was on accommodation (R14 593 279). On average soccer and rugby supporters from outside Bloemfontein spent 1,4 and 1,9 nights in Bloemfontein ,” said Dr Marais.

Rugby and soccer supporters were also asked to rate the quality of service received from amongst others hotels, guest houses, restaurants, and transport and entertainment facilities. Soccer supporters rated their satisfaction with services higher as rugby supporters. The rugby supporters gave the services at hotels a 3,9 rating, whilst soccer supporters awarded 4,6 rating out of a possible five.
