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 venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
