UFSAfricaWeek Make this Africa Day a day of reflection - Dr Stephanie Cawood

On 25 May 2018, we celebrate the 55th Africa Day since the Organisation of African Unity (OAU) was formed on this day in 1963. The conception of Africa Day, however, goes back to 1958 to the First Conference of Independent African States held in Accra, Ghana, hosted by Kwame Nkrumah. It was at that conference where Africa Freedom Day was first proclaimed and celebrated on 15 April to commemorate the progress of the African liberation movement as more and more African states gained independence. When more than 30 heads of state of independent African countries met in Addis Ababa, Ethiopia, to form the OAU (now the African Union) on 25 May 1963, African Freedom Day was dubbed African Liberation Day and moved to May. Today, known as Africa Day, it is commemorated across the African continent and the diaspora. 

What is the significance of Africa Day more than 50 years after its inception? African countries may have been liberated, but freedom is often qualified and limited by poverty persistent conflict, poor governance, neopatrimonialism, intolerance and other social injustices? Seen through a gender lens, one may well ask whether we have anything to celebrate when African women and sexual minorities carry such a heavy burden in daily struggles for survival and bear the brunt of persistent conflict. 

On this Africa Day, let’s rejoice in all the progress made since that very first commemoration. Let’s revel in all the vibrant cultural diversity in Africa and its diaspora, but let’s make this Africa Day a day of remembrance and reflection. As a day of remembrance, Africa Day should remind us of the liberation struggles that came before and it should prompt us to reflect on the struggles that remain in areas like gender equality and LGBTQI rights, poverty and sustainable livelihoods, social and environmental injustice, economic dependency, and conflict and what we can do to help effect change for the better. To quote an African proverb, “Use your tongue to count your teeth” for it is only through deep reflection that one will realise what needs to be done and how one should do it.

Scientists discover a water reservoir beneath the Free State
2009-12-09

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
