AEVGI advances Next-Generation Sequencing in Africa
Prof George Armah, Noguchi Memorial Institute for Medical Research, Ghana; Prof Carl Kirkwood, Bill and Melinda Gates Foundation, USA; Cornelius Hagenmeier, Director: Internationalisation, UFS; Prof Gert van Zyl, Dean: Health Sciences; Dr Martin Nyaga, Senior Lecturer in the NGS Unit; Prof Joyce Tsoka-Gwegweni, Vice-Dean: Health Sciences; Dr Glen Taylor, Senior Director: Research and Development; Prof Jeffrey Mphahlele, Vice-President, South African Medical Research Council.

The inaugural edition of the University of the Free State (UFS) Next-Generation Sequencing (NGS) Data and Bioinformatics Workshop, hosted by the UFS-NGS Unit in the UFS Faculty of Health Sciences, marked a new beginning for the advancement of NGS in Africa under the auspices of the African Enteric Viruses Genome Initiative (AEVGI), which was recently funded by the Bill and Melinda Gates Foundation.

The AEVGI will generate rotavirus genomes at the UFS-NGS Unit to investigate the long-term effects of the introduction of the monovalent RV1 vaccine in three African countries – Ghana, Malawi, and South Africa.

The workshop attracted over 90 participants from 15 national and international institutions, with organisations from seven different countries as well as company representatives attending the event. The workshop kicked off with a courtesy call to the Rector and Vice-Chancellor, Prof Francis Petersen, followed by a stakeholder meeting with the executive management of the UFS.

The funding was secured through an award to the principal investigator, Dr Martin Nyaga, and sub-awards to co-investigators, Dr Khuzwayo Jere, Dr Francis Dennis, and Dr Valentine Ndze. According to attendee evaluations of the workshop, the remarkable performance of the workshop instructors was outstanding. Through practical sessions, participants were equipped with knowledge on how to apply several tools of genetic data analysis, using the rotavirus genome as a model to construct and interpret different genomic datasets.

A total of 65 students attended the hands-on workshop, the majority of which were from South African higher-education institutions. The organisers are grateful to the sponsors, particularly to the Bill and Melinda Gates Foundation and the University of the Free State, for making the workshop a success. Whitehead Scientific and the South African Medical Research Council also played a major role in the success of the workshop. The local organising committee consisted of Dr Martin Nyaga (host, convener and chair), Dr Saheed Sabiu (secretary), and Mr Stephanus Riekert (principal ICT support).

Producers to save thousands with routine marketing strategies, says UFS researcher

Using derivative markets as a marketing strategy can be complicated for farmers. The producers tend to use high risk strategies which include the selling of the crop on the cash market after harvest; whilst the high market risks require innovative strategies including the use of futures and options as traded on the South African Futures Exchange (SAFEX).

Using these innovative strategies are mostly due to a lack of interest and knowledge of the market. The purpose of the research conducted by Dr Dirk Strydom and Manfred Venter from the Department of Agricultural Economics at the University of the Free State (UFS) is to examine whether the adoption of a basic routine strategy is better than adopting no strategy at all.

The research illustrates that by using a Stochastic Efficiency with Respect to a Function (SERF) and Cumulative Distribution Function (CDF) that the use of five basic routine marketing strategies can be more rewarding. These basic strategies are:
• Put (plant time)
• Twelve-segment pricing
• Three-segment pricing
• Put (pollination)(Critical Moment in production/marketing process), and
• Pricing during pollination phase.

These strategies can be adopted by farmers without an in-depth understanding of the market and market-signals. Farmers can save as much as R1.6 million per year on a 2000ha farm with an average yield.

The results obtained from the research illustrate that each strategy is different for each crop. Very important is that the hedging strategies are better than no hedging strategy at all.

This research can also be applicable to the procurement side of the supply chain.

Maize milling firms use complex procurement strategies to procure their raw materials, or sometimes no strategy at all. In this research, basic routine price hedging strategies were analysed as part of the procurement of white maize over a ten-year period ranging from 2002–2012. Part of the pricing strategies used to procure white maize over the period of ten years were a call and min/max strategy. These strategies were compared to the baseline spot market. The data was obtained from the Johannesburg Stock Exchange’s Agricultural Products Division better known as SAFEX.

The results obtained from the research prove that by using basic routine price-hedging strategies to procure white maize, it is more beneficial to do so than by procuring from the spot market (a difference of more than R100 mil).

Thus, it can be concluded that it is not always necessary to use a complex method of sourcing white maize through SAFEX, to be efficient. By implementing a basic routine price hedging strategy year on year it can be better than procuring from the spot market.
