South Africa is facing increasing water stress due to a variety of factors.

South Africa, like the rest of Africa, is facing increasing water stress due to a variety of factors, including inadequate maintenance and investment in water and sanitation infrastructure, unequal access to water, poor water quality, and increasingly unsustainable water demand. Flooding and drought disasters and disruptions in water and sanitation services have become more frequent in recent years amidst a growing population in a semi-arid country.

In addition to the ongoing load shedding crisis we are facing, South Africa is rapidly approaching a situation where “water shedding” is becoming a tangible issue. Although it hasn’t reached a nationwide scale yet, the occurrence of disruptions in water supply systems due to shortages and a combination of other factors is growing significantly.

This situation is detrimental, not only to South Africa’s developmental goals but also to its socio-economic position within the Southern African development community region and the continent as a whole.

This is according to academics from the University of the Free State (UFS) and the University of Pretoria (UP) who were part of a group of academics and industry experts who did an independent assessment of Operation Vulindlela’s impact on South Africa. Pres Cyril Ramaphosa unveiled Operation Vulindlela – a joint initiative of the Presidency and National Treasury that aims to modernise and transform network industries – in 2020 as the vehicle to “fast-track the delivery of economic reforms”.

Prof Paul Oberholster, Director of the UFS Centre for Environmental Management and an expert in wastewater treatment, and Dr Yolandi Schoeman, his Postdoctoral Fellow, together with Prof Emma Archer, Professor in Geography and Environmental Studies at the University of Pretoria were asked by Rand Merchant Bank (RMB) to focus on water.

Bring about the structural change

RMB states in the report that it commissioned a body of work by academics and industry experts to independently evaluate whether the execution of policy initiatives set out by Operation Vulindlela, would bring about the structural change that is necessary to accelerate SA’s growth and employment. The subsequent parts of this report focus on three of the five network industries identified by Operation Vulindlela – electricity, water and transport (ports and rail).

“It was an honour to have been part of this project with RMB and to unpack and strategically assess the water sector in South Africa. We know that there are plenty of challenges, but there are also remarkable opportunities where we can implement solutions and demonstrate impact, bring about change and work hard in turning the situation around as a joint constructive collaborative approach.

“They are very keen on working with leaders in the water space with qualities of strategic thinking, innovation, collaboration, inclusivity, and a strong commitment to sustainable development. It is an impactful contribution indeed,” says Prof Oberholster.

In their sections of the report, under heading South Africa's Blue Revolution: Investing in a thriving water future South Africa, Prof Oberholster, Dr Schoeman and Prof Archer, focused on five themes, namely Water for planetary health, Water for development, Water for climate, resilience and the environment, Water for cooperation and The Water Decade of Action.

“We were asked to evaluate the viability of what is still left to be done in the water sector in South Africa. We were asked to contribute our thinking to the RMB handbook for the purpose of distribution to corporate and institutional clients. As part of our outcome we provided clear and unbiased direction to RMB’s clients on the joint initiative the likely impact of Operation Vulindlela on economic growth and what still needs to be done to turn the water sector around,” according to Prof Oberholster.

Guidelines to improve the country’s water situation

He says their aim was to give guidelines on how to improve the country’s water situation. He believes the work they have done with this assessment and on other occasions, will help the UFS in its goal to be a university that impactfully supports societal development as set out in Vision 130, which states: Our knowledge will continue to contribute to the development of the Free State, South Africa, and the African continent and to advance global knowledge and understanding.

As clean water and sanitation is Goal 6 of the 17 Sustainable Development Goals (SDGs), it is a further indication of the importance of this research and work.

According to Dr Schoeman, reports like these are important because they help raise awareness of the challenges and opportunities for achieving water security and sustainable development. They identify problems and bottlenecks within the industry, helping to target areas that require immediate attention and action. They provide potential solutions and enable dialogue to the problems identified, giving stakeholders a roadmap for action and providing essential background that can enable investment and further inform investment priorities.

“Such reports help to inform planning and decision-making processes by providing data, evidence, and recommendations based on research and analysis.  They encourage collaboration and coordination among stakeholders by providing a common understanding of the issues and potential solutions.

“They also provide guidance and recommendations for decision-makers to improve water resources management and governance. Water is a vital resource for human health, food security, energy production, environmental protection and more, so it is essential to recognise its worth and incorporate it into planning and policies,” says Dr Schoeman.

Blue Revolution

The academics also talks about the Blue Revolution – essential blue solutions – in supporting Operation Vulindlela which can enable a sustainable future for South Africa's water management system. The Blue Revolution in South Africa, write the academics, refers to a comprehensive strategy and functional implementation for modernising and transforming the country’s water sector. It aims to improve water management practices and enhance the water sector’s overall efficiency, effectiveness, and sustainability in enabling planetary health.

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.
