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.”

Africa the birthplace of mathematics, says Prof Atangana

Prof Abdon Atangana from the Institute for Groundwater Studies at the University of the Free State recently received the African Award of Applied Mathematics during the International conference "African’s Days of Applied Mathematics" that was held in Errachidia, Morocco. Prof Atangana delivered the opening speech with the title "Africa was a temple of knowledge before: What happened?” The focus of the conference was to offer a forum for the promotion of mathematics and its applications in African countries.

When Europeans first came to Africa, they considered the architecture to be disorganised and thus primitive. It never occurred to them that Africans might have been using a form of mathematics that they hadn’t even discovered yet.

Africa is home to the world’s earliest known use of measuring and calculation. Thousands of years ago Africans were using numerals, algebra and geometry in daily life. “Our continent is the birthplace of both basic and advanced mathematics,” said Prof Atangana. 

Africa attracted a series of immigrants who spread knowledge from this continent to the rest of the world.

Measuring and counting
In one of his examples of African mathematics knowledge Prof Atangana referred to the oldest mathematical instrument as the Lebombo bone, a baboon fibula used as a measuring instrument, which was named after the Lebombo Mountains of Swaziland. The world’s oldest evidence of advanced mathematics was also a baboon fibula that was discovered in present-day Democratic Republic of Congo.

Another example he used is the manuscripts in the libraries of the Sankoré University, one of the world’s oldest tertiary institutions. This university in Timbuktu, Mali, is full of manuscripts mainly written in Ajami in the 1200s AD. “When Europeans and Western Asians began visiting and colonising Mali between the 1300s and 1800s, Malians hid the manuscripts in basements, attics and underground, fearing destruction or theft by foreigners. This was certainly a good idea, given the Europeans' history of destroying texts in Kemet and other areas of the continent. Many of the scripts were mathematical and astronomical in nature. In recent years, as many as 700 000 scripts have been rediscovered and attest to the continuous knowledge of advanced mathematics and science in Africa well before European colonisation. 

Fractal geometry

“One of Africa’s major achievements was the advanced knowledge of fractal geometry. This knowledge is found in a wide aspect of Africa life: from art, social design structures, architecture, to games, trade and divination systems. 

“The binary numeral system was also widely known through Africa before it was known throughout much of the world. There is a theory that it could have influenced Western geometry, which led to the development of digital computers,” he said. 

“Can Africa rise again?” Prof Atangana believes it can.

He concluded with a plea to fellow African researchers to do research that will build towards a new Africa.
