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.”

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
