A new research chair at the University of the Free State (UFS), led by Prof Maryke Labuschagne, a Professor of Plant Breeding in the UFS Department of Plant Sciences, hopes to increase food and nutritional security in South Africa through crops that have intrinsic high nutritional value.

The Breeding Climate-Resilient Vegetables and Grains research chair was established in partnership with the Agricultural Research Council (ARC) and the Department of Agriculture, Land Reform and Rural Development (DALRRD). It will be hosted within the Faculty of Natural and Agricultural Sciences (NAS) alongside the other ARC-DALLRD-UFS research chairs, namely Climate Change and Agriculture, Innovative Agro-processing for Climate-smart Food System, Agriculture Risk Financing and Sustainable Livestock Production.

The aim of the new ARC-DALLRD-UFS research chair, explains Prof Labuschagne, who is also leading the National Research Foundation (NRF) SARChI Chair in Diseases and Quality of Field Crops, is to breed climate resilient crops with high levels of nutrients such as iron, zinc, provitamin A and essential amino acids, as well as disease resistance, in collaboration with the ARC.

Breeding of climate resilient crops

“We are all aware of the need for food security in South Africa. Climate change is already negatively impacting food production. With this research chair, in collaboration with the ARC, we hope to increase food security through crops that have intrinsic high nutritional value, for example, high levels of iron and zinc and provitamin A, of which there are high levels of deficiency in our population, and at the same time increase climate resilience (such as heat and drought tolerance) in these crops.

“We will be working on breeding climate-resilient, nutrient-rich and disease-resistant pigeon pea and cowpea cultivars; maize rich in provitamin A, iron and zinc; highly nutritious sweet and bitter sorghum; rust-resistant and good-quality wheat; high-yielding and nutritious indigenous vegetables such as amaranth and amadumbi; and research on potato, sweet potato and cassava for human and industrial uses,” says Prof Labuschagne.

The new chair will complement the research that is already being done for the SARChI chair, but with the ARC as partner. It will combine the expertise and resources of Plant Breeding at the UFS with that of the ARC-VIMP (Vegetable, Industrial and Medicinal Plants), ARC-GC (Grain Crops) and ARC-SC (Small Grains). The chair research will include orphan crops such as cowpea, pigeon pea and indigenous vegetables, as well as root and tuber crops such as potato and cassava, and cereals such as wheat, maize and sorghum.

Collaborative research

“The focus of this chair is on collaborative research and student training with the ARC, but the research area will still focus on the development of nutrient-rich and disease-resistant food-security crops. It will also have an additional focus of climate resilience, and the inclusion of orphan crops indigenous to Africa and South Africa.”

Prof Labuschagne says it is exciting that collaborative research can now be done with the unique expertise and resources (laboratory equipment, fields, greenhouses etc.) of several research institutes for the benefit of food and nutritional security in South Africa. Doing this research in a large team with lots of expertise in different areas will certainly yield more and better results with a larger impact on food security.

“This is a very exciting development in agricultural research now that we are part of a large team all working towards the same goal of improving food security, sharing expertise and resources and also doing collaborative training of MSc and PhD students who will become the scientists of tomorrow, taking this quest into the future.”

Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, says this chair is aligned to the UFS Vision 130 strategy, shaped by excellence and impact, sustainability and society. “This distinguished chair led by Prof Labuschagne recognises exceptional achievement and pre-eminence in the field to catalyse and ignite new talent and new knowledge. It marks an exciting opportunity to deepen our understanding of breeding climate-resilient vegetables and grains aligned to our expertise in agriculture.”

Power interruptions: Information for internal communication

2008-01-31

As part of the UFS’s commitment to address load shedding, the management would like to communicate the following:

The UFS mainly deals with the power interruptions by way of (a) the possible installation of equipment (e.g. generators) and (b) operational arrangements to ensure the functioning of the UFS in spite of power interruptions.

During the past week progress was made on both fronts. The information that follows resulted from a meeting of a task team of Physical Resources led by Mr Nico Janse van Rensburg, which took place on Monday 28 January (this task team naturally focuses on physical solutions) and a discussion by Exco on Wednesday 30 January 2008. Exco discussed the recommendations of the mentioned task team in respect of physical aspects, as well as the operational arrangements proposed by faculties.

Physical solutions

A Main Campus

1. New emergency power installations already approved:

Last week Exco gave its approval for the design and installation of emergency power equipment in all the large lecture-hall complexes to proceed immediately.

In all these cases

load surveys have been completed and a start has been made with the ordering of equipment and the process of appointing contractors. (Exco approved the adjustment of normal tender procedures in an attempt to expedite completion.)
generators with 20-30% more capacity than required for the current load are being ordered.
provision is being made for the connection of lights and at least one wall plug to the emergency power.
the expected construction time is 16 weeks (except in the case of the Flippie Groenewoud Building where it is 6 weeks).

The above-mentioned concerns lecture halls/ venues in the following buildings: Examination Centre, Flippie Groenewoud Building, Stabilis, Genmin and the Agriculture Building.

As far as the Agriculture Building is concerned, a larger generator (larger than required for lecture venues only) is being ordered in view of simultaneously providing essential research equipment (refrigerators, ovens, glasshouses) with emergency power within 16 weeks.

2. Investigation into the optimal utilisation of present emergency power installations

All the emergency power systems are being investigated on the basis of a list compiled in 2006 to determine whether excess capacity is available and whether it is possible to connect additional essential equipment or lights to it.

The electrical engineer warns as follows:
“Staff members must under no circumstances overload present emergency power points.

A typical example of this is a laboratory with 10 power points of which 2 points are emergency power outlets. Normally a fridge and freezer would, for example, be plugged into the two emergency power points, but now, with long load-shedding interruptions, a considerably larger number of appliances are being plugged into the power point by means of multi-sockets and extension cords. In the end the effect of such connections will accumulate at the emergency generator, which will then create a greater danger of it being overloaded and tripping, in other words, no emergency power will then be available.”

3. Requests and needs addressed directly to Physical Resources or reported to Exco via the line managers.

All the physical needs and requests addressed directly to Physical Resources or submitted to Exco via the line managers are being listed, classified and considered technically in view of their being discussed by the task team on Monday 11 February.
The information will (a) lead to recommendations to Exco regarding possible additional urgent emergency power installations, and (b) be used in the comprehensive investigation into the UFS’s preparedness for and management of long power interruptions.

Requests that can easily be complied with immediately and that fit into the general strategy will indeed be dealt with as soon as possible.

4. Purchase of loose-standing equipment: light, small, loose-standing generators, UPSs as solutions to/ aids during power interruptions

Exco approved that

a) faculties and support services accept responsibility themselves for the funding and purchase of loose equipment such as, for example battery lights, should they regard these as essential.
b) UPSs (uninterruptible power supplies) that faculties and support services wish to purchase to combat the detrimental effect of unexpected power interruptions on computer equipment) can (as at present) be purchased from own funds via Computer Services.
c) UPSs (uninterruptible power supplies) that faculties and support services wish to purchase to combat the detrimental effect of unexpected power interruptions on other types of equipment can normally be purchased from own funds with the consent of the line manager concerned.
Note: Please just make sure of the appropriateness of the equipment for a specific situation: it is not a power supply that can bridge a two-hour power interruption.)
d) small, loose-standing generators can be purchased from own funds via Physical Resources and installed under their supervision.
e) laptop computers can , where necessary, be purchased from own budgets. The availability of second-hand laptop computers must be taken into account.

B Vista

No major problems have been reported to date. The situation is being monitored and will be managed according to need. The same guidelines that apply to the Main Campus will naturally also apply to the Vista Campus.

C Qwaqwa

The situation is receiving attentions and solutions have already been found for most problems.

D General

1. All-inclusive project
A comprehensive investigation into the UFS’s preparedness for and management of long power interruptions will be launched as soon as possible. Available capacity will be utilised first to alleviate the immediate need. The needs assessment to which all faculties and support services have already contributed is already an important building block of the larger project.

2. Building and construction projects currently in the planning and implementation phase
The need for emergency power for projects such as the new Computer Laboratory is being investigated proactively and will be addressed in a suitable manner.

3. Liaison with Centlec
Attempts at direct and continuous liaison are continuing in an attempt to accommodate the unique needs of the UFS.

4. HESA meeting and liaison with other universities
A representative of the UFS will attend a meeting of all higher education institutions on 11 February. The meeting is being arranged by HESA (Higher Education South Africa) to discuss the implications for the sector, the management of risks and the sector’s response to government.

5. Internal communication
It is the intention to communicate internally after every meeting of the task team, which will take place on Mondays. Strategic Communication will assist in this regard.
