Water Management: Contrasting approaches in Australia and South Africa

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.

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
