Dr Tafadzwa Clementine Maramura is a Senior Lecturer and NRF-Rated Researcher in the Department of Public Administration and Management at the UFS.

With roughly half the world’s population experiencing severe water scarcity for at least part of the year, according to the UN World Water Development Report 2024, a researcher from the University of the Free State (UFS) seeks to understand how South Africa and the rest of the African continent can ensure that every person has access to water.

Besides Dr Tafadzwa Clementine Maramura, Senior Lecturer and NRF-Rated Researcher in the Department of Public Administration and Management at the UFS, research focusing on service delivery, especially delivery of water to the most vulnerable and poorest households, her work also focuses on the water-health nexus. In February she was appointed the Secretary for the Institutional Governance and Regulations Framework – a sub-specialist group for the International Water Association (IWA), becoming the first black African female to be appointed to this position.

According to statistics quoted by Greenpeace, 5.52 billion people out of a population of 7.78 billion in 186 countries face water insecurity, of which, 1.34 billion are Africans, accounting for more than 90% of the continent’s population. The United Nations World Water Development Report 2024: water for prosperity and peace; facts, figures, and action examples state that as of 2022, 2.2 billion people were without access to safely managed drinking water.

 

Research focus

With this, and with the Sustainable Development Goals (SDGs) – especially Goal 6 (clean water and sanitation) – in mind, Dr Maramura seeks to understand how South Africa and the rest of Africa can ensure that everyone gets access to this particular resource. “My research focuses on water governance and sustainable service delivery, public policies, and the green economy in the African, as well as the South African, context. What I found is interesting and really saddening at the same time. When you break it down, you realise that one in every three people in Africa don’t have access to potable water.

“Water is a basic human right, you can survive without electricity and other luxuries, but not without water. Each time you brush your teeth or flush your toilet with at least 15 litres of clean water or you are watering your garden with clean water, there are people that actually don’t have access to basic drinking water,” says Dr Maramura.

She is also investigating what the government is doing to ensure it delivers on this service it is mandated to, as South Africa has all the policies in place, and the best constitution in the world, but still the poor and most vulnerable communities do not have water.

“Access to clean water is not just a basic need; it is a matter of dignity, equality, and survival. As a young African woman, through my research, I see first-hand how the burden of water scarcity falls disproportionately on women and girls, robbing us as women, of education, economic opportunities, and health.

“But we are not just victims – we are leaders in this fight. By empowering women and investing in sustainable water solutions, we can transform our communities and break the cycle of poverty. The time for action is now because water is life, and every African deserves it.”

 

The water-health nexus

Dr Maramura has book chapters coming out in June this year that focus on the water-health nexus in failed states, thereby merging SDG 3 and 6 on health and water respectively. Water plays an indispensable role in the world as it is important for accomplishing several other SDGs, such as zero hunger, poverty eradication, good health and well-being, and affordable and clean energy. It all depends on the achievement of goal 6.

Says Dr Maramura: “You cannot solve problems in isolation; you cannot look at the water problem in isolation. If you have a water problem, you have a health and education problem because kids can’t go to school if there is no water. Hospitals can’t function when there is no water.

“SDG 3 speaks to health and SDG 6 speaks to water and that is where the nexus is, nexus meaning connection between water and health. How can we ensure that we merge the two together and ensure researchers working on health and water can find common ground to address any challenges arising from the lack of water so that we don’t have these health issues?”

South Africa is an upper-middle-income country but still struggles to deliver potable water to everyone and many communities in the country still rely on ventilated pit latrines due to limited access to modern sanitation facilities. With the deadline for achieving the 17 SDGs only five years away, South Africa is at risk of failing to achieve the SDGs.

 

Solving the water problems

According to Dr Maramura, there is no magic wand that can be used to solve all the country's water problems, but a collaborative and comprehensive effort is needed. “There is work that needs to be done. The government, private sector, the communities, as well as other role players need to work together. South Africa is a water-stressed country with rainfall below the global average. We realised that we have scarce groundwater resources.

“The community needs to understand, participate, and be aware of how much damage we can do by just drilling boreholes and digging wells. The private sector needs to know what it is that they can do to ensure that they also play a part through their corporate social responsibility and philanthropic dimensions in assisting the community.”

From the government side, she says, the policies are there so the government needs to consult with the communities, the private sector, and all other relevant stakeholders. They need to involve affected communities and after consultations, they need to engage these communities because they understand their problem best.

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.”
