Research informs about sustainable use of fresh water for food production

The fact that South Africa is a water-scarce country has been highlighted during the past couple of years, and even city dwellers were suddenly very aware of the drought due to the strict water restrictions. These are the words of Dr Frikkie Maré, Head of the Department of Agricultural Economics at the University of the Free State (UFS) and one of the graduates who received his PhD on water-footprint assessment studies at the recent June 2018 graduations.

The department is currently involved in various water-footprint and water-management research projects which assist in providing solutions for better water management in the future. “As department, we want to be at the forefront of research that will assist all agricultural producers with sustainable production practices to ensure economic, environmental, and social sustainable food and fibre products for the society at large,” said Dr Maré.

Research funded by Water Research Commission

The UFS recently conferred two PhD degrees (Drs Enoch Owusu-Sekyere and Frikkie Maré) and one master’s degree (Adetoso Adetoro) in the Department of Agricultural Economics. All three have been working in the field of water-footprint assessment. The research formed part of two different projects that were initiated and funded by the Water Research Commission.

According to Dr Henry Jordaan, Senior Lecturer in this department, four of his students already received their master’s degrees on the topic of water-footprint assessment, while two students are busy with PhDs and three more are working on their master’s degrees.

Topic gains momentum in research community
The water-footprint concept serves as a useful indicator to sensitise society about the impact of the food we eat on scarce freshwater resources – from agricultural producers using water to produce primary food crops and products on the farm, to the end consumer buying the food products in the retail store in town.

“Water-footprint assessment is a relatively new field aimed at informing the sustainable use of fresh water for food production. This topic is gaining momentum in the research community, given the substantial increase in the global population in the context of freshwater resources that is getting increasingly scarce. The challenge is to feed the growing population while still using the scarce freshwater resources sustainably.

Volume of water used to produce food

“In order to inform water users on how to use the resource sustainably, it is important to know the volume of water that was used to produce the required food products. Through our research, we are contributing to this knowledge by assessing the volume of water that was used to produce selected products, and to interpret the water use in the context of water availability to gain insight into the degree of sustainability with which the resource is used. The results are expected to inform water users, water managers, and policy makers regarding the sustainable use of fresh water for food production,” said Dr Jordaan.

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.
