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.

UFS on energy-saving mode
2009-09-15

The University of the Free State (UFS) has undertaken several measures to reduce energy consumption on the Main Campus in Bloemfontein.

“Part of Eskom’s strategy is that all the main universities must reduce their electricity consumption. Because the university is the second biggest user of electricity in Bloemfontein we have to cut our consumption according to the new energy policy,” said Prof. Niel Viljoen, Chief Director of Operations at the UFS.

“Electricity is also expensive and if we look at global warming and everybody’s responsibility, I think we all have a moral obligation to save energy,” said Prof. Viljoen.

“The energy crisis of January 2008 and beyond, with its load-shedding limitations, was a major driver for the government to introduce the Power Conservation Scheme,” said Mr Anton Calitz, the UFS’s electrical engineer.

The measures put in place by the UFS include amongst others:

The introduction of a solar water-heating system in the residences, which is a first of its kind in Bloemfontein.
An investigation is also being launched into alternatives and the effective heating of rooms in the residences.

Feasibility studies are currently being conducted to determine whether energy saving can be achieved with radiation panels.

Energy-saving lights have been installed in the following buildings: the Architecture Building, Genmin Lectorium, Geology lecture halls, Winkie Direko Building, George du Toit Building, Sasol Library, Francois Retief Building, as well as in the residences. This measure has resulted in massive energy saving.

Energy meters for the Library, Computer Laboratory Building, François Retief Building and Steyn Substation are being planned as the first phase.

Real-time metering will result in every UFS computer user being aware of power consumption on the campus.

New lift motors and control systems that reduce energy consumption have been installed at the Agriculture and the George du Toit Buildings.

In the Computer Laboratory Building the temperature adjusting point for the venues is set at 22 °C and, in the case of new projects, green guidelines are applied.

It is expected that the government and local authorities will bring more pressure to bear on the UFS to save energy. Applications for increased capacity will possibly be linked to energy-saving targets.

This trend will continue until 2014 when additional power stations will be put into operation.

“Our aim is to save 10% on energy consumption,” said Prof. Viljoen.

“Heavy financial penalties will be imposed if a 10% saving is not achieved,” added Mr Calitz.

On average, our energy consumption per day this year is 128,964 kWh as compared to last year’s 119,752 kWh.
