WomenofKovsies Dr Lize Joubert on flowers and their favourite insects
Pollination is important to maintain diversity in our natural ecosystem and maintain ecosystem health

“Pollination is important to maintain diversity in our natural ecosystem and maintain ecosystem health.” So says Dr Lize Joubert, lecturer in the Department of Plant Sciences at the University of the Free State. “Research helps to understand the interaction between insects and flowers and their many implications on real-world problems.”

Plant systematics and pollination biology, Dr Joubert’s research field, looks at how plants diversify, adapt to environmental changes and how their flowers evolve to keep attracting insects to pollinate them for reproduction. 

Dependency on pollination

Crop production is, in many cases, dependent on pollination. About 75% of the world’s crops are to some extent dependant on pollination. “Pollination is really important for us as human beings, but it is also important to maintain diversity in our natural ecosystem and maintain ecosystem health.”

Dr Joubert obtained her PhD in plant systematics in 2013 and was subsequently awarded the EM van Zinderen-Bakker Prize for an outstanding PhD dissertation in Botany.

She is also the curator of the Geo Potts Herbarium in Bloemfontein, the internationally accredited herbarium housing over 30 000 plant specimens, mainly representing the flora of central South Africa and several special collections from Marion Island, the Okavango Delta, and KwaZulu-Natal. 

Learning from the experts

As a young researcher Dr Joubert became part of the Prestige Scholars Programme (PSP) at the UFS which led her to Cambridge University where she became part of a research group for nearly two years under an expert in her field, Prof Beverley Glover. The PSP at UFS identifies and promotes promising young academics at the university to become full professors with excellent research accomplishments. 

Dr Joubert views the PSP Programme to a large extent as her academic home. She is proud to be part of the programme that has brought her closer to other experts in her field and resulted in collaborations in which she is involved in cutting-edge research.

Successful conviction on edible oil adulteration
2009-03-28

A successful conviction in the South African food industry for selling diluted olive oil under the guise of virgin olive oil was handed down in the Special Commercial Crimes Court in Durban this week.

Salvatore Pollizi, owner of the company Ital Distributors, pleaded guilty in terms of Section 105A of the Crime Prosecuting Act to selling fake virgin olive oil under the names of Antico Frantoio and Ulivo.

He was sentenced to a fine of R250 000 or three years’ imprisonment, of which R130 000 or 18 months imprisonment is suspended for five years, on condition that he is not found guilty of fraud or theft or an attempt to commit such crimes during the period of suspension.

The offence was committed in 2001 when the scandal involving olive oil being mixed with a cheaper edible oil and being sold as the more expensive virgin olive oil was uncovered by scientists from the University of the Free State (UFS) in Bloemfontein, in collaboration with Mr Guido Costas, The Olive Growers’ Association, AgriInspec and the South African Police Services.

According to Prof. Lodewyk Kock, Head of the South African Fryer Oil Initiative (SAFOI) that is based at the UFS, the conviction is to his knowledge the first successful conviction of this kind in the South African food industry.

Prof. Kock said, “The court’s decision on Monday, 23 March 2009 is good news to our country and sends out a dire warning to all fraudsters in the food industry.”

He attributed the successful conviction to the active and enthusiastic participation by Advocate Joanna Bromley-Gans from the Special Commercial Crime Unit (SCCU) in Durban, Captain Pragasen Govender from the Serious Economic Offences Unit (SEOU) in Pretoria and the team from SAFOI.

Prof. Kock said that in 2003 some of the prominent members of the edible oil industry took responsibility for the authenticity of their own oils by appointing outside laboratories for routine monitoring.

In some cases a seal of approval from such laboratories is displayed on the monitored oil containers. This is an attempt to inform oil distributors, shop buyers and consumers that these oils have been monitored by an outside laboratory for authenticity.

This “policing” has been supported by major role players in the fast-food sector like Nando’s, Spur, Captain Dorego’s, King Pie Holdings, etc. and various oil distributors like Felda Bridge Africa, Willowton Oil & Cake Mills, Refill Oils, etc.
