Geologist shares ground-breaking findings at Alex du Toit lecture

The Department of Geology at the University of the Free State (UFS) was recently the host of a lecture in the 2018 Alex du Toit Memorial Lecture series.

The speaker at this event was the A-rated NRF researcher, Prof Lew Ashwal from the University of the Witwatersrand. He addressed academics and geology students on ‘Wandering continents of the Indian Ocean’.

Lost continent found

In this talk he specifically shared the research he conducted on the islands of Madagascar (which he visited 30 times to conduct field work and says it is not for the faint-hearted), the Seychelles, and Mauritius. 

Two things stood out in his lecture: the way in which his findings on the three islands helped to refine details about the assembly of the Gondwana supercontinent, and the report of a ‘lost continent’ found under Mauritius. 

These discussions were linked by Prof Ashwal’s belief that the so-called lost continent he found under Mauritius is a leftover from the break-up of Gondwana,

The discovery was made when he and a team of researchers found zircon from 2000 million years ago on a 9-million-year-young island. He believes that the piece of crust (where the tested zircon probably formed), which was covered by lava during recent volcanic eruptions on the island, is a tiny piece of the ancient continent which broke off from Madagascar, when Africa, India, Australia and Antarctica split up and formed the Indian Ocean.

Media frenzy 

The fact that the team of researchers found these extremely old minerals proves that there are materials under Mauritius that originated from a continent under the island. 

Prof Ashwal is studying the break-up process of the continents in order to understand the geological history of the planet.

For his work Prof Ashwal has enjoyed coverage from publications as far apart in focus from each other as The New York Times and Cosmopolitan magazine.

MSc student plans to FEED our hungry planet

Since attending the 2014 Youth Ag-Summit in Canada, Lisa Coetzee – an MSc student in Plant Pathology in the Department of Plant Sciences at our university – developed a plan to address hunger:

FEED – Forum of Education, Empowerment and Development.

Coetzee, together with a junior lecturer at Plant Sciences, Marguerite Westcott, started this student association to tackle the issue of food insecurity head-on.

Education, empowerment and development “are keywords vital to the solutions to poverty. Hunger is an issue which is found in our own homes. One in every four South Africans is food insecure. Hunger kills more people every year than Aids, malaria and TB combined,” says Coetzee.

“This forum allows awareness to be raised about the hunger situation locally and globally. FEED is talking about hunger and it is assisting in reducing it by reaching out to communities which are in need.

“FEED is the generation which is going to make a difference in eradicating hunger,” Coetzee continues. “We want students to think about how they can feed the hungry through what they are studying”. For Coetzee it is a high priority to ensure that the youth are aware of the importance to feed our hungry planet in a sustainable way.

Her philosophy on relieving hunger and increasing food safety is to enhance the efficiency of crop production, ensure crop security and reduce mycotoxins in the food we eat.

During the 2014 summit, Coetzee was elected to represent the African delegates on the Youth Ag Summit Committee. Ever since, she has been enthusiastically active in the agricultural community. As 43% of the globe’s farmers are women, Coetzee also feels she acts as a voice for female farmers in South Africa.

An important lesson Coetzee has learned is that there is power in one person to make a change – that we should start small but think big.
