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.

Machinery and equipment to the value of R6 million acquired by UFS Instrumentation Division

At an information session held on the Bloemfontein Campus, the Instrumentation Division in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) introduced its new Computer Numeral Control (CNC) machines to the value of R6 million.

Initially, the primary aim of the Instrumentation workshop was to design, produce, and maintain special research equipment which is unavailable on the market, mainly for academic departments. The small-scale production focused on producing support material and equipment for research work.

However, with new equipment and machinery the Division now also can deliver a service to corporate companies and external associates.
 
The CNC machines include a 5-axis Vertical Machining Centre from Haas imported from America. This is one of only four in South Africa, with two in Johannesburg and one in Cape Town.  The lathe makes it possible to produce sophisticated parts, which were previously cumbersome and difficult to make. The machines also cover a wide spectrum in the mechanical field such as the the FLOW Water Jet, which cuts a wide variety of material ranging from titanium to wood without utilising heat, thus saving electricity. This makes it possible to cut a wide variety of materials.

With the new machinery now available, the Instrumentation Division is able to perform high quality and quantity production with precision.

“The advantage of the machinery is that it stimulates production, and is much faster and more accurate than the conventional way of doing things,” said Pieter Botes, Head of the Division.

Botes explained that, by having students and professional artisans at the university design and manufacture equipment, costs are reduced when compared with the expensive nature of equipment and tools found in the market. In addition, “the machines broaden the scope of research conducted” said Botes. The technical dynamics of the machinery advances the scientific knowledge needed to operate it, so bridging the gap between theory and practice.

The Central University of Technology, Signs Division Bloemfontein, Product Development Technology Station (PDTS), Maizey’s, and Knottco Truckparts are some of the university’s trade partners.

The workshop collaborates with the Chemistry, Physics, Microbiology, Botany, Agriculture, and Electronics departments, as well as the Institute of Groundwater Studies at the UFS, and others. These departments receive services in the form of pipette stands, containers for test tubes, bottles, laboratory trolleys, stands for cadavers for Anatomy, pump repairs, stainless steel bailers, filaments, and heaters.

The Instrumentation Division is, therefore, a vital support unit for the Faculty of Natural and Agricultural Sciences as well as the university at large.
