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.

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
