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.

Link between champagne bubbles and the UFS?

What is the link between the bubbles in champagne and breakthrough research being done at the Mayo Clinic in America? Nano research being done at our university.

Prof. Lodewyk Kock of Biotechnology says a human being consists of millions of minute cells that are invisible to the eye. The nano technology team at the UFS have developed a technique that allows researchers to look into such a cell, as well as other microorganisms. In this way, they can get an idea of what the cell’s “insides” look like.

The UFS team – consisting of Profs. Kock, Hendrik Swart (Physics), Pieter van Wyk (Centre for Microscopy), as well as Dr Chantel Swart (Biotechnology), Dr Carlien Pohl (Biotechnology) and Liza Coetsee (Physics) – were amazed to see that the inside of cells consist of a maze of small tunnels or blisters. Each tunnel is about 100 and more nanometres in diameter – about one ten thousandth of a millimetre – that weaves through the cells in a maze.

It was also found that these tunnels are the “lungs” of the cells. Academics doing research on yeast have had to sit up and take notice of the research being done at the UFS – to the extent that these “lungs” will appear on the front page of the highly acclaimed FEMS Yeast Research for all of 2013.

The Mayo Clinic, in particular, now wants to work with the UFS to study cancer cells in more detail in order to fight this disease, says Prof. Kock. The National Cancer Institute of America has also shown interest. This new nano technology for biology can assist in the study and development of nano medicine that can be used in the treatment of cancer and other life threatening diseases. Nano medicine uses nano metal participles that are up to one billionth of a metre in size.

Prof. Kock says laboratory tests indicate that nano medicine can improve the efficacy of anti-cancer medicine, which makes the treatment less toxic. “According to the Mayo Clinic team, nano particles are considered as a gold cartridge which is being fired directly at a cancer tumour. This is compared to fine shot that spreads through the body and also attacks healthy cells.”

“This accuracy implies that the chemotherapy dose can be lowered with fewer side effects. The Mayo Clinic found that one-tenth of the normal dosage is more effective against pancreas cancer in this way than the full dosage with a linkage to nano particles. According to the clinic, this nano medicine could also delay the spread of cancer,” says Prof. Kock.

The nano particles are used as messengers that convey anti-cancer treatment to cancer cells, where it then selectively kills the cancer cells. The transport and transfer of these medicines with regard to gold nano particles can be traced with the UFS’s nano technology to collect more information, especially where it works on the cell.

“With the new nano technology of the UFS, it is possible to do nano surgery on the cells by slicing the cells in nanometre thin slices while the working of the nano medicine is studied. In this way, it can be established if the nano medicine penetrates the cells or if it is only associated with the tiny tunnels,” says Prof. Kock.

And in champagne the small “lungs” are responsible for the bubbles. The same applies to beer and with this discovery a whole new reach field opens for scientists.
