Farmers who depend on the Loskop Dam to irrigate their crops can breathe a sigh of relief after scientists found the water poses no immediate threat to human health, which means exports of fruit and vegetables are safe — at least for now.
CSIR warns that the water quality in the Loskop Dam is deteriorating rapidly
“It’s a great relief,” said the Loskop Irrigation Board’s Diek Engelbrecht yesterday.
Farmers have been so worried about the declining water quality in the heavily polluted Olifants River, which flows into the dam, that the irrigation board commissioned a study from the Council for Scientific and Industrial Research (CSIR) and the University of Stellenbosch. Farmers were concerned that if their crops became contaminated with heavy metals or pathogens, their produce would no longer make export grade.
The dam provides water to 16000ha of agricultural land, and supports a European export market worth about R1bn a year.
The Transvaal Agricultural Union (TAU) last year said its members were worried that polluted water would jeopardise their livelihood. If they lost their export markets, they would have to dump produce locally and prices would fall, with knock-on effects for farmers who rely on domestic customers, it said.

If SA was able to recycle its total national water resource 1,7 times over by 2035, the country’s unemployment problem would be solved, International Water Resources Association vice-president Anthony Turton said yesterday.

SA’s government is battling a 24% unemployment rate (4,1-million people), as measured by Statistics SA in the last quarter of last year, and has promised, in its New Growth Path economic plan, to create 5- million jobs by 2020.
While the ability to recycle water would not of itself create jobs, without this ability the necessary preconditions for the kind of economic growth that would create jobs would not be in place, Dr Turton told Business Day after his presentation to the inaugural Water and Energy Forum which ended in Sandton yesterday.
“We can incentivise and do whatever we like, but we will create jobs and lose them again if we don’t recycle our water…. In order to sustain growth we need 62-billion cubic metres of water and we have 3 8- billion cubic metres now,” he said.
However, for the first time in history SA’s economic and infrastructure development was constrained by environmental considerations, Dr Turton said in his presentation. SA’s water resources were increasingly compromised by growing demand and looming pollution problems from decades of mining that did not take the environment into consideration.

Professor Anthony Turton, vice-president of the International Water Resource Association, explains how to beat the water crisis.
The media is abuzz with talk about the developmental state so I have tried to understand this rhetoric in the context of water.
If we think of national economic growth as an “S” curve on a graph, on which the vertical axis represents value and the horizontal axis time, then we can see that early development is slow as technology is mobilised. This manifests as a flat part of the curve. As the economy kicks into overdrive, the curve climbs rapidly, such as happened in South Africa during the latter part of the 20th century. This growth slows down, either because of external constraints, such as reduced global commodity demand, or as a result of internal constraints. It is my hypothesis that the South African economy has reached the upper part of this first “S” curve, of which two limitations are the most apparent from a biophysical perspective.
The first constraint is energy, which we all know about. The second is water, which few of us know about, but which is starting to become manifest in the public domain. Significantly, water is our energy constraint, not coal. It takes 1kg of coal and 1.35kg of water to produce one kilowatt hour of electricity with the technology used by Eskom.
So what are we to do? Continue reading Water is our energy constraint, not coal
