Research ties between the University of the Free State, the University of Tokyo, and the International Christian University strengthened when the Japanese scholars visited the Afromontane Research Unit (ARU) on the Qwaqwa Campus. 

“The visiting delegation is part of the larger research group on sustainability studies that has been sharing research expertise with the Afromontane Research Unit’s researchers over the past three years,” said Dr Kudo Shogo, Assistant Professor from the University of Tokyo’s Graduate Programme in Sustainability Science – Global Leadership Initiative (GPSS-GLI).

Entrepreneurship in Qwaqwa
“Our focus this time is on entrepreneurs who have had exposure to megacities such as Johannesburg and Cape Town, and who are finding themselves back in places like Qwaqwa. We have discovered that they actually find Qwaqwa more resourceful than when they left. Two to three years of unstable living in the cities gave them a fresh view to see the many opportunities in Qwaqwa and they then start their businesses. Talking to the Qwaqwa entrepreneurs has been a great learning experience for all of us,” he added.

The visiting scholars conducted interviews with 10 local entrepreneurs to get a sense of how they use entrepreneurship for sustainability purposes.

“We are pleased by the local people’s understanding that local problems require local solutions. I would really like to contribute to these people’s understanding of how these solutions fit the problems better than solutions that come from outside. We have quite a number of voices talking about empowering Qwaqwa, with the emphasis on creating jobs for Qwaqwa, solving the problems that Qwaqwa is facing. I have found education to be a unifying factor through tutoring, after-school classes, mentorship, and the personal imperative of sharing,” said Emilie Jones, originally from the United States of America and now studying for a master’s degree in Sustainability Science focusing on water supply and resources.

Education and arts empower communities
“Most of the entrepreneurs we spoke to have experience of the big cities. For them, Qwaqwa is very close to the heart and is home. There are challenges, but they are doing their best to empower their community with ideas and skills from the big cities. They provide services such as education and arts to empower the community to come up with a local identity,” said a PhD candidate, Ven Paolo Valenzuela from the Philippines. 

“I was impressed with the people who realise the opportunities to identify problems and even come up with solutions themselves. A lot of communities can learn from this,” said Gema Carlota Cubelos Perez, a PhD candidate originally from Spain.

Their host, Dr Melissa Hansen, Lecturer from the Department of Geography, said the visit was part of the bigger study on migration and sustainable development. “This was a Global Field Exercise (GFE) for teaching research methods in the field. We found that Qwaqwa is overflowing with potential for entrepreneurship in a wide variety of fields and that there is a strong, vibrant network of young individuals brimming with talent. We are learning from each other, as Akita City in Japan and Qwaqwa are similar in more ways than one,” she said.

One of the entrepreneurs, Refiloe Seekane, is a self-taught fashion designer, choreographer, and event coordinator. “The interview has actually made me realise the gaps we have for business opportunities in Qwaqwa and the importance of implementing some of the projects I have been planning for years,” said Seekane, a second-year Education student and CEO of Evomind.

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
