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.

The field of Nuclear Medicine in South Africa and the rest of the world are expanding rapidly due to the development of hybrid cameras and new radiopharmaceuticals. These developments have a huge impact on the diagnosis and therapy of cancer.

The most advanced of these cameras, Positron emission tomography combined with normal CTs (PETCT), are not yet widely available in South Africa due to the cost of the cameras and the radiopharmaceuticals. A more cost-effective alternative can be of great benefit. To achieve this, the focus should be on developing new radiopharmaceuticals that can be used with the current cost-effective gamma cameras, according to University of the Free State researcher, Dr Je’nine Horn-Lodewyk from the Department of Nuclear Medicine.

Fluorodeoxyglucose (18F-FDG), a radiolabelled glucose analogue, is currently the radiopharmaceutical most commonly used in PET/CT imaging for mainly oncology indications. Although it is considered the gold standard for imaging in several malignancies, it does have certain disadvantages. An 18F-FDG PET/CT diagnostic imaging study can cost between R25 000 and R35 000 for a single patient in the private sector. The 18F-FDG is also more radioactive, which requires much stricter handling and shielding to avoid high radiation dosages to staff and patients.

Successful research potential innovative solution
In the search for the ideal radiopharmaceutical for tumour detection, the South African National Nuclear Energy Corporation (Necsa) developed a local synthesis process for ethylenedicysteine-deoxyglucose (EC-DG). EC-DG is also a glucose analogue similar to FDG. They succeeded in labelling the compound with Technetium-99-metastable-pertechnetate (99mTcO4-), the most common nuclear medicine isotope used for approximately 95% of nuclear medicine procedures, creating 99mTc-EC-DG.

In partnership with Dr Horn-Lodewyk, this compound was successfully used in various animal models and clinical scenarios, resulting in approval by the Medicine Control Council to use it in a human study. Research is also planned in order to investigate diagnostic accuracy in other cancers like lymphoma.  The end result of this research can produce a radiopharmaceutical that is cost effective, does not require the use of costly specialised equipment, has no significant side-effects, no special patient preparation, renders late imaging possible, and has decreased radiation risks.

Dr Horn-Lodewyk is grateful for the support of her mentor, Prof Anton Otto, as well as Dr Gert Engelbrecht, Head of the Department of Nuclear Medicine, Prof Jan Rijn Zeevaart from North-West University’s Preclinical Drug Development Platform and Necsa, and Judith Wagener from Necsa. This innovative research would also not have been possible without the financial assistance of Dr Glen Taylor and Eleanor van der Westhuizen in the Directorate of Research Development.
