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.”

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
