Zama Zama
Michelle Goliath played a major role in establishing the first ethically sourced, fair, women-owned, artisanal diamond process.

Michelle Goliath, a PhD student in the Department of Urban and Regional Planning at the UFS, has a passion for helping the most vulnerable people in society who have run out of conventional employment options. 

“My research includes ‘Zamaism’ psychology, a philosophy which looks at the contestation of space and rules, how people navigate the illegal when they are faced with desperate choices,” she explains.  

Michelle has been working with approximately 3 000 diamond mining ‘Zama Zamas’ (criminal miners) over the past three years. Together, they negotiated an agreement with private sector mining and public sector stakeholders to include the Zama Zamas as legal artisan miners in the formal mining economy.

One of the highlights of her career so far was being part of a big first: the complete, ethically sourced, fair, women-owned, artisanal diamond process.

Michelle explains: “A rough stone includes the story of the women who dig it from the earth, legally (under permit), ethically sourced. Instead of being exploited, the same women now sell their diamonds for full value to a legal tender house through a legal buyer or directly to the cutter and polisher. The cutter and polisher also train the women to cut and polish the stones themselves. The women then sell the stones to jewellery gold- and silver-‘smiths’ who artisanally craft this into an engagement ring or ‘Wakanda gem spear’, to be sold in the open market locally and internationally.”

She believes these products will become priceless works of art. “Like Picasso paintings, they are each uniquely produced by hand with a story and Kimberley process certificates,” she adds.

The story of the women

This project had a big impact on Elisa Louw, a former street seller and domestic worker. She tells her story: “I was tired of domestic work and decided to work at the mines as a Zama Zama. I began with nothing and had to borrow tools and learn from others.”

Elisa started working in the mines in 2013; in 2014, she found her first 75-pointer diamond which she sold for R1 500 on the black market. “The black market was good then,” she said.

She later recruited other Zama Zamas to register and obtain legal permits for mining. Elisa mined from 08:00 to 12:00 and from 13:00 to 16:00 she recruited people to start a legal mining co-op. “It was difficult then. People did not understand what it meant to be legalised,” Elisa explains.

But she worked hard and at the end of 2016, the Batho Pele Primary Mining Cooperative was established.

However, it was a hard and difficult journey before they were given their permits early in 2017. The mines took their IDs and issued them with eviction letters. “They called us names – terrorists, robbers, rapists, etc. But in a meeting with the South African Police Service, the Department of Mineral Resources, the Sol Plaatje Municipality, and the international Swedish Housing Company, Michelle spoke for us.”

“She represented the Swedish Housing Company and we thank the Lord for sending her to us. She informed all parties that we did not want to fight, but that we were looking for a licence to work. She helped us to obtain our legal permit to mine.”

“It was such a relief when we received the permit. I could go home and sleep without worrying about the safety of the old people and children who are mining.

“The permit changed my life as a woman. My voice is heard; my words count. I am proud of myself,” says Elisa. 

The two cooperatives they created, Batho Pele Primary Mining Cooperative and the Women in Artisanal Scale Mining, have already signed agreements with Canada and the USA for the export of fair-trade-certified gem products.

Blood, sweat and tears

The journey towards this big achievement took two years of literally blood, sweat, and tears. “Society labels Zama Zamas negatively as terrorists. In a way, you become a Zama at heart once you live with people every day who are fighting for economic inclusion. You fight the illegal diamond trade that exploited people as digging slaves. You fight formal mining, which is a difficult sector to enter as a woman. You literally fight others with stones for territory. You fight political fights, land fights, the system at every level, to seek an existence,” Michelle explains.

She believes the mining industry can be a tough environment. “It is exploitative at many levels. It showcases rare talent, but under duress. At artisanal scale it is even worse. The only future women have, is to lead themselves, to create their own fairer system, to redesign a full value chain that allows broader participation,” states Michelle.

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
