Dr Mutana and Prof Mukwada
Many people enjoy spending time in the mountainous Drakensberg region. Prof Geofrey Mukwada’s involvement with the UFS Afromontane Research Unit (ARU) sparked an interest in sustainable tourism in the area. Pictured here are Dr Sarudzai Mutana with Prof Mukwada.

Not only is the Qwaqwa Campus situated in a beautiful region – its researchers also contribute to keeping the area pristine. Recent research by Prof Geofrey Mukwada and his PhD student, Dr Sarudzai Mutana, focused on indicators monitoring sustainable tourism development in the Drakensberg region.

Dr Mukwada is an Associate Professor in the Department of Geography on the University of the Free State (UFS) Qwaqwa Campus. 

Our majestic mountains are fragile

Many people enjoy spending time in the mountainous Drakensberg region – either as adventure seekers exploring the many trails, or just relaxing and reconnecting with nature. Prof Mukwada’s involvement with the UFS Afromontane Research Unit (ARU) sparked an interest in sustainable tourism in the area. “Mountains are fragile but attractive environments which continue to attract tourists,” he said. “Tourism is one of the major business sectors in the Drakensberg region, with promising growth opportunities and proving to be an anchor of green economy in the future – if practiced correctly.” Unfortunately, the issue of monitoring sustainable tourism has not been widely researched in African mountains. 

According to international standards

“We specifically looked at the Global Sustainable Tourism Criteria (GSTC), which is an international best-practice framework to help destinations monitor and ensure that tourism is developed in a responsible manner,” Prof Mukwada explained. “South Africa’s Manual for Responsible Tourism was designed according to some of the recommendations of the GSTC. But we found that, while the tourism and hospitality operators in the Drakensberg region appreciates the need to monitor and ensure sustainable tourism in the area, there is limited use of indicators as a tool for monitoring.” 

Forward together

There are competing demands between land-use and development practices and alternatives in the region – unless the focus shifts to sustainable practices, the short-term gains could be followed by dire consequences. “We suggest an integrated monitoring of tourism development, with a pro-poor focus that involves more local community leaders. Going forward, we would like to see the industry adopt the indicators proposed in our study.”

UFS researcher engineers metal surfaces

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
