Our Relentless Water Dilemma
Dr Tseliso Ntili, HOD of the Free State Department of Water and Sanitation, warns that pollution caused by mismanagement of municipal water-treatment works puts severe pressure on the province’s water security.


“Despite our water challenges, Bloemfontein will never become a second Cape Town.” This firm assurance was given by Dr Tseliso Ntili, HOD of the Free State Department of Water and Sanitation, during his presentation at the recent regional seminar of the Faculty of Law’s Environmental Law Association.

The theme of the seminar was Water Quality and Water Security in Bloemfontein and was attended by staff and students from the Faculty of Law and the Faculty of Natural and Agricultural Sciences, as well as relevant role players from private, business, and government sectors.

Not enough water for city’s needs

Water restrictions in some form do seem to remain part of our future landscape though, as Dr Ntsili explained that the city’s current water yield of 218 megalitres per day still fell short of the demand of 259 megalitres per day.
 
Pollution and mismanagement at municipal level

He pointed out that a big cause for concern was that 75% of the Free State’s waste-water treatment works were dysfunctional. Housekeeping and security at these plants are often severely neglected. Yet, it is difficult for the Department of Water and Sanitation to act against offending municipalities.

“In intra-governmental disputes, the courts must be satisfied that organs of state have taken all reasonable steps to settle contentions – which can be a time-consuming process,” he explained.

Dr Ntsili said that the Caledon River System’s dwindling water levels due to low rainfall and siltation was also a concern, but that plans were underway to supplement the water supply to Bloemfontein via the Gariep Dam by 2026.

However, he warned that poor water management could drastically affect these long-term plans.

“If we can’t manage pollution, the cost will be high. Water security will be challenged, and we will have water shortages – not because of drought, but because of negligence.”

Plant-strengthening agent a result of joint effort between UFS and German company
2015-07-27

Research over the past few years has showed that the agent applied mostly as a foliar spray subsequently leads to better seedlings as well as growth and yield enhancement of various crops.

The application of a plant-strengthening agent in the agricultural industry has, until recently, been largely ignored, says Dr Elmarie van der Watt of the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS). The agent was co-developed by researchers at the UFS and a German company.

The product is moving into new markets, such as China, Vietnam, the USA, and Australia.

ComCat® was the result of extensive research by the German company Agraforum AG. Commercialisation was limited initially to Europe, while research was expanded to other parts of the world, with the University of the Free State as the main research centre.  ComCat® is a unique, non-toxic plant strengthening agent derived from wild plants. It enhances plant growth and yield, as well as resistance against abiotic and biotic stress factors.

Dr Van der Watt says that, in nature, plants communicate and interact by means of allelochemicals (the inherent silent tool of self-protection among plants) and other phytochemicals (chemical compounds that occur naturally in plants), as part of their resistance mechanisms towards biotic and abiotic stress conditions.

Most wild-plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent. “Active compounds contained in extracts from wild plants applied to monoculture crops can potentially supply the signal for the latter to activate their dormant resistance mechanisms.” 

Research over the past few years has showed that the agent applied mostly as a foliar spray subsequently leads to better seedlings as well as growth and yield enhancement of various crops.  A major advantage is that, despite its enhancing effects on root development and yield, it does not induce unwanted early vegetative growth that could jeopardise the final yield, as happened in the past for nitrogen application at an early growth stage. 

Dr Van der Watt says, “Physiological data on the effect of the natural bio-stimulant product on photosynthesis, respiration, and resistance towards biotic stress conditions indicate that it can be regarded as a useful tool to manipulate agricultural crops. Research also showed that the field of application for this natural product is never-ending, and new applications are being investigated every day.”
