Opinion article by Prof Anthony Turton, Centre for Environmental Management, University of the Free State. 


South Africa and Australia, both arid countries with historical ties to the British Empire, face significant water management challenges. Despite common legal and parliamentary systems, the two nations diverge in their approaches to water sector governance, leading to markedly different outcomes in economic prosperity.

In examining the disparities, it becomes evident that contemporary South Africa is grappling with a scenario resembling a failed state, particularly evident in the breakdown of the electricity and water services sector. This raises a fundamental question – why is the South African water sector faltering while its Australian counterpart thrives? 

Why is the South African water sector collapsing?

Addressing the collapse of the South African water sector requires a nuanced understanding rooted in historical context. The origins of the issue can be traced back to the British Empire’s consideration of federalism during the Anglo-Zulu War. While federalism found success in Canada and Australia, it failed to take root in South Africa.

Fast forward to the present, South Africa operates as a unitary state with a centralised water policy and national water law. This uniform approach leaves little room for local variation, resulting in a cookie-cutter model applied nationwide. Despite water being a constitutional right and given that free basic water is guaranteed to all, the sector faces challenges such as high levels of unaccounted-for water, leakages, and poor management. The absence of justiciable water rights and the separation of water from land ownership hinder private sector involvement. Consequently, utilities are reliant on government bailouts, a situation exacerbated by failing water and electricity grids, diminishing the tax base, and escalating unemployment. 

Australia’s flourishing water sector: A model of innovation 

Australia’s federal structure facilitates a diverse array of state policies and laws, promoting adaptability to local conditions. Boasting over 30 distinct water authorities, each tailored to meet local needs, Australia thrives on a justiciable water right system that allows private ownership. Market forces drive water to its most productive use, and investor confidence is a cornerstone in decision-making. 

Australia’s innovative and market-oriented approach has resulted in well-managed utilities with robust balance sheets. The ability to raise capital from the bond market reduces reliance on public funds for bailouts. Groundwater plays a vital role, accounting for around 40% of the total resource, while innovative technologies, such as seawater desalination, are embraced at the utility scale.   

South Africa’s water sector: uninvestable and facing challenges 

Contrastingly, South Africa’s water sector faces challenges. A lack of innovative approaches, coupled with a rigid, cookie-cutter methodology has stifled local imagination. The state’s hostility towards private capital has rendered the water sector generally uninvestable. While some large water boards still maintain strong balance sheets, the growing debt burden from non-payment by municipalities poses a threat. Limited development of groundwater at utility scale, coupled with a reluctance to replicate successful initiatives, further compounds the challenges. Sea water desalination, where it exists, is confined to small package plants in distressed municipalities along the coast, often seen as unsustainable. 

Australia’s innovative solutions: integrating technology and conservation

Australia stands out for its innovative solutions. With a vibrant private sector driving constant technological advancements, groundwater is a key element in most utilities, actively integrated into the grid and accounting for around 40% of the total resource. Building codes align with water conservation, ensuring rainwater harvesting and aquifer recharge are actively pursued at various levels, including suburb and city. The management of sewage, increasingly sophisticated water recovery from waste, and seawater desalination at utility scale funded by private capital showcase Australia’s forward-thinking approach.  

Centralisation versus decentralisation  

In conclusion, the weakness of South Africa’s water sector lies in the highly centralised approach, resulting in ineffective, one-size-fits-all solutions. Local authorities often lack imagination, relying heavily on taxpayers and hindering innovation. Suspicion towards capital and technology further limits the sectors development. In contrast, Australia’s decentralised approach fosters vibrant water utilities capable of attracting both capital and technology. Entrepreneurs’ initiatives in desalination and water recovery programmes inspire investor confidence, leading to capital influx and secure, water-efficient local economies.

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.
