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 keeps the power on
2015-06-24

 

At a recent Emergency Power Indaba held on the Bloemfontein Campus, support structures at the university met to discuss the Business Continuity Intervention Plan to manage load shedding on the three campuses of the UFS.

Currently, 35 generators serving 55 of the buildings have already been installed as a back-up power supply on the three campuses of the university. According to Anton Calitz, Electrical Engineer at the UFS, the running cost to produce a kWh of electricity with a diesel generator amounts to approximately three times the cost at which the UFS buys electricity from Centlec.

Planned additional generators will attract in excess of R4 million in operating costs per year. For 2015, the UFS senior leadership approved R11 million, spread over the three campuses. Remaining requirements will be spread out over the next three years. University Estates is also looking at renewable energy sources.

On the Bloemfontein Campus, 26 generators serving forty-one buildings are in operation. On South Campus, two generators were installed at the new Education Building and at the ICT Server Room. Lecture halls, the Arena, the Administration Building, and the library will be added later in 2015. Eight generators serving 12 buildings are in operation on the Qwaqwa Campus. In 2015, the Humanities Building, Lecture Halls and the heat pump room will also be equipped with generators.

Most buildings will be supplied only with partial emergency power. In rare cases, entire buildings will be supplied because the cost of connecting is lower than re-wiring for partial demand. According to Nico Janse van Rensburg, Senior Director at University Estates, emergency power will be limited to lighting and power points only. No allowances will be made for air-conditioning.

“Most area lighting will also be connected to emergency power,” he said.

Where spare capacity is available on existing emergency power generators, requests received for additional connections will be added, where possible, within the guidelines. The following spaces will receive preference:
- Lecture halls with the lights, data projectors, and computers running
- Laboratories for practical academic work and sensitive research projects
- Academic research equipment that is sensitive to interruptions
- Buildings hosting regular events

According to Janse van Rensburg, all further needs will be investigated. Staff can forward all emergency power supply needs to Anton Calitz at calitzja@ufs.ac.za

Staff and students can also manage load shedding in the following ways:

1. Carry a small torch with you at all times, in case you are on a stairwell or other dark area when the lights go out. You can also use the flashlight app on your phone. Download it before any load shedding occurs. This can come in handy if the lights go out suddenly, and you cannot find a flashlight. Load-shedding after dark imposes even more pressure on our Campus Security staff. We can assist them with our vigilance and preparedness by carrying portable lights with us at all times and by assisting colleagues.
2. Candles pose a serious safety risk. Rather use battery- or solar-powered lights during load shedding.
3. Ensure that your vehicle always has fuel in the tank, because petrol stations cannot pump fuel during power outages.
4. Ensure that you have enough cash, because ATMs cannot operate without electricity.
5. The UFS Sasol Library has study venues available which students can use during load shedding.
6. When arranging events which are highly dependent on power supply, especially at night, organisers should consult the load-shedding schedule before determining dates and preferably also make back-up arrangements. If generators are a necessity, the financial impact should be taken into consideration.

The senior leadership also approved a list of buildings to be equipped with emergency power supplies.
