Zama Sithole, a master’s student in Environmental Managementat the University of the Free State (UFS), would one day like to assist communal artisanal small-scale miners (ASM) to legalise their work. Although the ASMs are not involved in turf wars or criminality as in the case of zama-zamas, they are deemed illegal workers.

The prime mining legislation, the Mineral and Petroleum Resources Development Act, makes no provision for subsistence or communal ASM activities. Such miners are therefore considered illegal miners.

“ASM employs more than 20 million people globally and a country such as South Africa, with an unemployment rate of 30,1%, should assimilate this type of mining as a legal form of employment,” says Zama.

“Their only client base is the surrounding communities. Mining, besides government grants, is their only source of income.”

Zama aspires to assist the illegal miners to become legal and reap the benefits of skills and funding to increase their income.

“And guidance from the regulatory authorities will ensure that the communal ASM miners become more aware of environmental management,” she adds.

Zama recently presented her research, titled: Shortcomings of the South African Legislative Framework in Addressing Communal Artisanal Small-scale Mining: A Blaauwbosch Case Studyat the 2020 Environmental Law Association (ELA) Annual Student Conference.

She also received the award for Best Speaker at the conference.

In her research, Zama focuses on Blaauwbosch, a rural township area located south-east of Newcastle in northern KwaZulu-Natal, where subsistence coal and clay opencast mining by community members has been going on for more than four decades.

Environmental degradation

According to the Mineral and Petroleum Resources Development Act, mining is only deemed legal if there is a mining permit, mining right, production right or preferent mining right authorised by the Department of Mineral Resources. Since communal ASMs are unregulated, environmental degradation is rife.

According to her investigation, environmental hazards such as traces of acid mine drainage and poor air quality (due to spontaneous combustion), are localised in the area. This is a deterrent to the surrounding community that has minimal health and safety awareness.

Owing to the fact that communal ASM miners are not assimilated into the legislation, the competent authorities such as the Department of Mineral Resources and Energy and the Department of Water and Sanitation cannot offer mineral regulation and environmental guidance support.

Losing revenue

Zama says government is also losing revenue by not legalising this unique sector. She believes it is important to differentiate between communal ASMs and the ‘zama-zama’ type of mining.
 
She also found that according to the Mining and Minerals Policy (1998), “regulations in respect of mining should be relevant, understandable and affordable to the small-scale miner and should be enforced in a site-specific manner.” ... “Tax and royalty rates, levies, and financial guarantees for rehabilitation should not constrain the development of small-scale operations.”

“However, to date, this has not been realised,” Zama states.

Communal ASM miners thus cannot benefit from government-funded initiatives to upskill them in terms of mining and environmental management.

Making a difference

Zama plans to conduct more research to understand the dynamics of how other countries have legalised this sector and draw learnings from this to determine how it can be applied in the South African context.

“In our country, there is very limited data and hence understanding on communal ASM. This could be one of the reasons why the government cannot make an informed decision on how to legalise this sector,” she says.

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.
